HSE Officer Interview Questions with Answer
Q1. Suppose You are doing daily site activity monitoring and you saw one person doing an unsafe act, you intervened and advise him but he didn’t listen to you then what action will you take?
Ans- First I will stop him and tell him that he is doing unsafe and this can cause severe injury to him, if he listens then the issue is rectified, if he didn’t care about my advice then I will call his line supervisor, and will ask him why he’s one of a crew member is doing unsafe in his control?
Then again, I will talk to the violator in front of his supervisor and will inform his supervisor to talk to him about the correct way of safe work, if the violator agrees to do it safely and never repeat it again in the future then the matter is rectified.
If he still not listens then consequence management will be applied and 1st warning letter to be issued against the violator.
Q2. Why Mobile is not allowed in the Refinery or Oil & Gas Plant?
Ans- As normal Mobile phones are not intrinsically safe, meaning that they have the potential to produce a spark of such intensity that could ignite vapor mixed in the air, it makes sense to keep potential sources of ignition away from these areas.
Q3. How is Arc blast caused?
Ans- Due to discharge of high electrical current through open air.
Q4. Why Current measurements are more dangerous to make with a multimeter than voltage measurements?
Ans- The fuse protects the voltage measurement ranges, but not the current.
Q5. What is the difference between ELCB and RCCB?
Ans- Both are used for one purpose to protect equipment from damage and electric shock. Before people used ELCB but now RCCB is an updated version of ELCB.
Q6. Why ELCB is very rarely used?
Ans– ELCB can not be used without earthing but RCCB can be used without earthing, second difference is that RCCB ensures 100% of leakage current & is available to sense the AC as well as DC leakage current. ELCB is not preferable as it can only detect current that flows back through the main earth wire.
Q7. What is the difference between D Shackles and Bow Shackles?
Ans- A “D” Shackle is shaped like a D with straight sides and designed to take loads in line with sides, not at an angle to them.
A “Bow” shackle is similar but with rounded sides and can take loads at a variety of angles to the shackle Centre line.

Q8. How many types of drills?
Ans- There are many types of drill but it depends on plant activities, for example. Mock Drill, Spill Drill, Confined Space Drill, etc.. five types of drill are in maximum places.
1) Man down rescue drill
2) H2S drill
3) Muster drill
4) fire drill
5) Evacuation drill
Q9. How many types of SAFETY NET?
Ans- There are two types:-
1) Man arrest
2) Material arrest
Man arrest safety net hole Diameter Std is 100 mm, Rope outline Dia 8 mm
Material arrest safety net hole Dia is 25 mm, Outline Rope Dia is 12 mm
Q10. Which units are used in pressure tests?
Ans- Units of pressure are Bar, PSI, Kg/Cm², KPA
100 Kilo Pascal means 1 bar
1 bar=14.504 PSI( 14.5 pounds-force per square inch)
1 bar means 10197.16 Kg/Cm (you can say 1.01 Kg/Cm ²
1 PSI = how many KPA so 100÷14.5
6.895 Kilo Pascal
Q11. What steps you would take for those employees who are involved in doing violations again and again? How will you motivate them to follow safety procedures or compliance
Ans- First of all I will monitor and try to find out the root cause that why they do so and what’s the reason behind the violation. If anything is lacking or a behavioral issue, then I will make them understand the advantages of following the safety and the disadvantages of not following.
I will motivate them emotionally that if they don’t work safely then they may face injury and even death if got injured then their family will be affected even they will lose their life. Once you lose your life who will take care of your family? You are here to earn money not to lose any body parts so” Think about your family, you came here to earn money and you have to go back home safely.
Q12. Name equipment those are used for work at height activities.
Ans- 1) Fixed Scaffolding.
2) Tower scaffolding
3) Mobile Elevated Working Platforms (MEWPs)
4) Ladders and stepladders.
5) Swing stage scaffolding Or cradles.
6) Rope access.
7) Robotics, can reduce or even eliminate the need for workers to operate aerial lift equipment. Robots can reduce the risk of falls from height.
Q13. Can employees wear a respirator with high blood pressure or asthma?
Ans- Before wearing a respirator must first have a medical check-up. If people have breathing problems such as asthma, a heart condition, severely high blood pressure, or are extremely sensitive to heat, they may not be able to work wearing a respirator.
Q14. Can you explain SIMOP (Simultaneous activities) activities and their precautions? How can you control safety?
Ans- SIMOPS is defined as performing two or more operations concurrently. It’s a very challenging job for a safety person to tackle such situations. Identify all operational activities that may be concurrently undertaken at the same time.
Identify if there is a potential hazard associated with the two operations occurring simultaneously. Describe the normal safeguards required by the safety management systems that are applicable before any particular operation can be performed, for example- PTW.
Q15. How to Calculate the Safe Working load of a wire rope sling?
Ans- To calculate the SWL of fiber rope in kilograms, square the rope diameter (D) in millimeters (mm)
Now the question is the lifting capacity of 20 mm Dia of fiber rope?
Formula: SWL (kg) = D2 (mm)
Diameter = 20 mm
SWL (Kg) = D2 (mm)
SWL (kg) = D (mm) x D (mm)
= 20 x 20
= 400 kg
SWL (t) = 0.4 tones.
Now how we can turn Kg into mm? The equation can be reversed to calculate the diameter (D) in millimeters of fiber rope needed to lift a given load. To do this, find the square root of the load in Kilograms.
Formula: D (mm) = √Load (kg)
Load = 200 kg
D (mm) = √200
= 14.14 mm
Therefore a 15 mm diameter fiber rope sling is required
Q16. What precautions must be followed when transporting storing and using CO2?
Ans- Always store CO2 cylinders upright, and always safely away from any overhead items that could potentially fall onto the tanks. Never place or store anything on top of your CO2 cylinders or micro-bulk containers. Never store your CO2 tanks near flames or anything that emits high heat
When CO2 increases in the air, like with a leak from a micro-bulk container, and accumulates in a confined enough space, it can cause suffocation and death.
CO2 is 1.5 times heavier than air, so any leaking gas will sink toward the bottom of the air column, accumulating around the floor or in trenches or sumps. leaking CO2 can mix with moisture in the air. When this happens, a weak acid known as carbonic acid forms, and this can actually eat away at carbon steel pipes.
Q17. What is a Shutdown in an Oil and Gas Plant? Or what is the purpose of the Shutdown in Oil and Gas?
Ans- We can answer differently on the above question. I explain to you simply that Shutdown is a term often used in Oil & Gas to conduct planned maintenance on process equipment for which normal routine operations have to be suspended or can be stopped (in an interview you can only explain the above sentence).
(Below lines for understanding)
A shutdown is normally planned for 30–45 days on average. When the ZERO day starts, all the operations are closed, equipment is internally cleaned with flush, steam, or inert then allowed to cool, manholes are opened, preliminary equipment internal & external inspections are carried out Shut down purpose is the maintenance of equipment. For installation of new equipment and for cleaning of piping (piping cleaning is done through flushing, steaming, or purging).
Q18 What are the hazards of Plant Shutdown? activities and safety precautions?
1) Fire and explosions
2) Toxic gases
3) Slips or trips or Falls and Falling Objects.
4) Chemical Exposure.
5) Electrical Hazards. ( Due to not following LOTO)
6) Repetitive Motion Injury
7) Using damaged tools
8) Confined space( mostly activities in shut down are in confined space)
9) Improper functioning of safety devices
Activities in Shutdown-
1) Hot work
2) Erection of piping and equipment
3) Confined space
4) Electrical work
5) Work at a height
6) Mechanical shutdown activities on columns, heat exchangers, air coolers, furnaces, tanks, and fittings, etc.
7) Cleaning of piping and Exchangers
Before starting shut down job take the following precautions:-
1) Proper planning. Before starting a job plan properly
2 Distribute jobs to concerned workers. Workers must know their role in activities. There shouldn’t be a misunderstanding
3) Proper guidance or supervision
4) Training to workers including activities hazards, plant
5) Fire safety and safety devices etc.
Q19. How many options of ventilation are there in Confined Space and how long you should Ventilate confined space?
Ans- There are two options for ventilating in a confined space:
1) Forced-air ventilation: Uses fresh, forced air to ventilate a confined space by displacing and diluting air.
2) Exhaust ventilation: Uses an exhaust to continuously remove contaminants at the source point.
Ventilation of confined space depends on:-
1) The size and configuration of the confined space
2) The size of the entrance into the space
3) The gas present within the space and the amount
Ventilate the space for a minimum of 30 minutes, up to 60 minutes, and Conduct the gas test again to check the atmosphere.
Q20. What is the Purpose of a Work Permit?
Ans- The work permit eliminates accidents, controls work, and people, and communicates.
To do Restricted Activity (Hazardous Activity) Safely.
To do specific work on a specific location or equipment.
Restricted areas require permission to enter. (e.g. cannot enter in Confined Space
By issuing a permit, the Issuer knows where and who is working in his area of
responsibility and at the end of the job, by closing permit he came to know about the status of the job and/or equipment.
Q21. What is the difference between CO and CO2?
Ans- Both CO2 and CO are odorless and tasteless. Elevated levels of both gases can cause health problems and even death. The critical chemical difference is that CO2 contains one atom of carbon and two atoms of oxygen, whilst CO has one carbon and one oxygen atom. Carbon dioxide(CO2) is non-flammable, while carbon monoxide is flammable.
Carbon monoxide is produced when energy is released from burning fossil fuels, natural gas, and oil. As well, carbon dioxide is emitted as part of both plant and human respiration. Once carbon dioxide is released it quickly mixes into the atmosphere. Humans and animals breathe in oxygen and exhale carbon dioxide – we can tolerate a small amount of it. However, carbon monoxide does not occur naturally in the atmosphere and can cause health problems even in low concentrations.
The source of carbon dioxide is smoke stove heaters etc. The most important difference between them is the density. Carbon dioxide is heavier than air and gas detectors should be put nearer the ground, whereas carbon monoxide is slightly lighter and detectors should be placed higher up.
Q22. How will you protect workers if any compressed gas cylinder leaks What is the best protection when approaching an acetylene leaking cylinder and the regulator is not working?
Ans- If it is necessary to move a leaking cylinder through populated portions of the plant or workplace. secure a plastic bag, rubber shroud, or similar device over the top of the cylinder to confine leaking gas. Keep flammable or oxidizing gases away from combustible materials.
Q23. What are the things HSE has to check in cranes before lifting?
Ans- Hot work permit or lifting permit before starting of job. If more than multiple cranes are using risk assessment shall be done.
- Crane third-party certificate (Plate number, Validity, any Remarks, and Number of falls).
- Operator Third Party & License.
- Rigger Third Party and its Validity
- Safety certificate and Fire Extinguishers of the Crane.
- Crane outriggers and mates.
- Crane computer function.
- Anti tube block/limit switch (it will stop the function of the crane hook once it touches and it will prevent the hook from hitting to top boom pulley.
- Lifting appliances like (wire rope sling, webbing sling, D shackle, and chain block)
- Third-party certificate (validity 6 months) and don’t use beyond its SWL.
- Damage and expired lifting tools and tackles shall not be used.
- Safety latch of a main and auxiliary hook.
- A hydraulic leak of oil.
- The cabin of the crane shall be free from a blind spot.
- PPE of working crew especially leather gloves for rigger and safety harness.
- Swing area clear or not
- The operating area should be no objections
All these things need to be checked and have a written checklist to carry out inspection and give the approval to operate.

Q24. Explain Control Measures with an example Answer Control measures include actions that can be taken to reduce the potential of exposure to the hazard, or the control measure could be to remove the hazard or to reduce the likelihood of the risk of exposure to that hazard being realized.
Ans- If workers sweep the floor and wear goggles to protect their eyes, that’s a control measure.
If you send staff on a training course to understand how to do something safely, that’s a control measure.
If you provide an item of equipment that makes the task safer, that’s also a control measure.
Q25. What is Carbon Monoxide and where it can lethal or dangerous? How can you recognize without a detector?
Ans- Carbon monoxide is a colorless, odorless, tasteless gas produced by burning gasoline, heaters, stove vehicles, wood, propane, charcoal, or other fuel. Improperly ventilated appliances and engines, particularly in a tightly sealed or enclosed space, may allow carbon monoxide to accumulate to dangerous levels. In these situations, carbon monoxide can be dangerous or lethal.
There are some signs of headache vomiting, and dizziness but remember these signs to recognize without a detector.
1) Brownish or yellowish stains around appliances.
2) A pilot light that frequently goes out.
3) The burner flame appears yellow instead of clear blue
HSE Officer Interview Questions with Answer / HSE Supervisor Interview Questions
Ans- The following are considered special scaffolds:-
- Any scaffold over 38 meters (125 feet) tall
- A tube and coupler scaffold that exceeds the maximum limits.
- Any scaffold cantilevered extended outward by more than 3 meters
- Any scaffold with a total platform area over 30 square meters (320 sq. ft.) that is supported by or hung from an existing structure (e.g., building, roof, pipe rack, offshore platform) or is within 3 meters (10 feet) of any other scaffold supported by or hung from the same structure.
- Any scaffold supporting loads greater than 240 kg/sq.m. (50 Psf), including piping,
equipment, masonry, new or existing structures, or loads other than workers and
- Any scaffold supported by or hung from one or more outrigger beams
- Any scaffold supported by or hung from wind girders or roofs of floating roof tanks.
Note:- Any scaffold whose height extends more than 40 feet then they will be considered a special scaffold and a special scaffold, and the plan is required by the scaffold engineer.
Ans- LUX’s Latin name is illumination. It’s the std unit of measurement lighting. As per IS 3646 of 1996 code practice for Lux for-
Canteen 150 Lux
Cloak/ store room 100 Lux
Stairs(especially) Entries, corridors 100 Lux
Assembly shop &Rough work 150 Lux
Medium work. 300 Lux
Fine work 700 Lux
Bedroom (General) 300 lux for children 500 lux
Bathroom 150 Lux
Kitchen 300 Lux
Note:- It’s only lightning whose hazards are the same in both conditions
Poor lighting at work can lead to eye strain, fatigue, headaches, stress, and accidents. On the other hand, too much light can also cause safety and health problems such as “glare” headaches, strain, and stress.
Q28. What are the sources of Hydrogen Sulfide in air, plants, and at home?
Ans- Most Hydrogen Sulfide (H2S) in the air comes from natural sources. It is produced when bacteria break down plant and animal material, often in stagnant waters with low oxygen content such as bogs and swamps. Volcanoes, hot springs, and underwater thermal vents also release hydrogen sulfide.
Industrial sources of Hydrogen Sulfide include petroleum and natural gas extraction and refining, pulp and paper manufacturing, textile production, chemical manufacturing, and waste disposal.
At our Home, Hydrogen sulfide gas is a natural product of decay, and in a residential area, is most commonly a result of decomposition in septic or sewer systems.
Q29. Explain symptoms you could experience if you are exposed to Hydrogen Sulfide (H2S)?
Ans- Symptoms of acute exposure include nausea, headaches, delirium, disturbed equilibrium, tremors, skin and eye irritation, and convulsions. Inhaling high concentrations can produce extremely rapid unconsciousness and death. Dermal exposure to liquefied gas can cause frostbite injury.
Q30. Being an HSE Officer What would you do if a project fell behind schedule and it was your fault?
Ans- Several problems can set a project back, but in a high-hazard industry like construction, accidents remain a too-frequent cause of delays and a danger to workers. Serious accidents cause significant delays and even can shut a project down while an incident investigation takes place.
Because accidents can affect construction project timelines, construction superintendents need to bring safety to the forefront to help ensure that a project stays on schedule. When safety is viewed on an equal footing with budget and schedule, it helps to reinforce those elements.
The focused planning and performance necessary to ensure that a project is completed safely are crucial in keeping it on schedule and budget.
Q31. Which Fire Extinguisher can be used in Confined Space, Why not DCP?
Ans- When a CO2 extinguisher is used in a confined space there is a danger that the user may become overwhelmed by the sudden increase in carbon dioxide emissions. This occurs as CO2 is an asphyxiant, and the confined space means oxygen will be replaced by CO2 much faster.
Care must also be taken when using (DCP) powder extinguishers, When the powder is discharged it can impair visibility and impact the breathing of the user, possibly jeopardizing their escape (exit). The possibility of the powder being inhaled or impairing visibility is increased when this type of extinguisher is used within a confined space.
Q32. Which Fire extinguishers are liquid and gas? Which fire extinguisher is toxic powder?
Ans- Foam fire extinguishers contain liquid and are suitable for both class A type and B type fire. For example petrol or diesel.
Three types of extinguishing agents are typically used— Carbon dioxide, Dry chemicals, and Foam water for fires involving flammable liquids, greases, and oils. Carbon dioxide is a compressed gas agent that prevents combustion by displacing the oxygen in the air surrounding the fire.
No fire extinguisher is toxic. The dry powder in ABC fire extinguishers is non-toxic but can cause skin irritation.
Q33. What are Hot tapping and pressure tapping? When to avoid Hot Tapping and what precautions should be taken?
Ans- Hot tapping, or Pressure tapping, is the method of making a connection to existing piping or pressure vessels without interrupting or emptying that section of pipe or vessel.
This means that a pipe or tank can continue to be in operation whilst maintenance or modifications are being done.
Hot tapping is not recommended under any of the following conditions:-
- Piping containing a combustible or flammable mixture.
- Piping contains acids, chlorides, peroxides, or other chemicals that are likely to decompose or become hazardous from the heat of welding (e.g., sulfuric acid or acetylene).
- Piping containing caustic.
Piping that contains pure oxygen or chlorine.
- Airlines where the absence of hydrocarbon cannot be assured.
- Monel piping handling sulfur compounds.
- Stainless steel piping containing catacarb solution
Q34. Why should we cover compressed gas from Direct Sunlight or heat?
Ans- The heat causes the content will become more reactive. The safety valve of the compressed gas will be activated the gas inside the cylinder will cause the pressure to increase. The high temperatures will cause the cylinder to explode.
Q35. How to calculate load percentage in a crane?
Ans- Crane % capacity = Hook block + Material weight / SWL × 100
Just an Example:-
Crane capacity = 100 ton
Hook block = 4 ton
Material weight = 8 ton
SWL = 15.5 tons (By using Crane Load Chart )
= 4 + 8/ 15.5 ×100
= 77.41 %.
Q36. How to calculate Crane boom radius?
Ans- Radius= 360 ÷ boom length + boom height
Example- 360÷ 15mtr + 10mtr ?
360÷ 25= 14.4
Radius = 14.4mtr
Q37. What is immediate action required during the failure of the Hydrotest?
Ans- In the event of a failure during the pressure test, the system will be immediately depressurized by cracking the vent on the test pump manifold.
After the pressure has been released, the vent valves shall be opened. The cause of failure shall be determined and rectified before any further pressure testing is undertaken.
Q38. What are chemicals which don’t impact the environment but impact health?
Ans- A common one is Nitrogen (N2) which is available in the atmosphere at 78% but getting directly exposed to pure nitrogen could be dangerous also oxygen is good for the environment and excess oxygen is good for the environment but getting pure oxygen could lead to organ failure in the human body.
Q39. How many types of heavy equipment or machinery are in construction?
Ans- Types of Heavy Equipment or Machinery Used in Construction. Heavy Duty Equipment means high-capacity mechanical devices for moving earth or other materials.
- Excavators are also called diggers, mechanical shovels, or 360-degree excavators.
- Skid loader
- Crawler loaders
- Wheeled loading shovels
Material Handling Equipment-
- Concrete Mixture
- Road Rollers
- Road Headers
- Tunnel Boring Machines (TBM)

Q40. What can be dangerous due to a Fire Extinguisher being overcharged? What action should we take immediately?
Ans- A fire gauge extinguisher can be “overcharged” meaning the contents are under too much pressure, “discharged” meaning that there is not enough pressure to work correctly, or “in the green” means that the unit is properly charged.
An overcharged fire extinguisher can cause leakage or worse, a cylinder explosion.
Action:- Immediately removed from the site forward the cylinder to the manufacturer for replacement.
Q41. What are safe procedures to weld on a vehicle?
Ans- When it comes to replacing panels and other body components, there are a few precautions to take to protect the vehicle while welding. Avoid welding near electrical systems or with the battery connected. Make sure the battery is disconnected and all systems are shut down before the welding process.
Be careful of burning painted surfaces, glass, moldings, and the interior. Remove all moldings in the area to be welded and remove glass if possible. If unable to remove the glass, make sure it is covered with a spark-resistant material. Also, cover painted surfaces and exposed interiors to prevent a fire.
Avoid welding near NVH and other foams/sealers. Remove foams, sealers, adhesives, and inserts from the welding area. Products like those previously listed are highly flammable and can ignite rapidly and travel to other parts of the vehicle.
Q42. What do you mean by NVH?
Ans- Noise, Vibration, and Harshness also known as noise and vibration, is the study and modification of the noise and vibration characteristics of Vehicles, Particularly cars and trucks.
Q43. What is hazardous energy? How can they be controlled?
Ans- Any Electrical, Mechanical, Hydraulic, Pneumatic, Chemical, Nuclear, Thermal, Gravitational, or Other energy that can harm workers, Hazardous energy is controlled by LOTO and other methods. For Example:- Barrier or guard system to the machine Stored energy can be controlled or protected by allowing a blade to completely stop rotating before servicing; Releasing pressurized steam and/or water lines by opening the proper relief valve.
Q44. How to clean the tank or drum of oil before welding?
Ans- There are three important points to remember before cleaning oily tanks or drums.
- If the substance is soluble use the washing method. For nonsoluble substances use either the boiling or steaming method.
- Cleaning must be thorough. DO NOT try to take shortcuts. If the CLEANING must be done by someone else, it’s to ensure that the person is fully aware of the hazards.
- You must check the presence of residues in the tank or drum after carrying out the cleaning procedures. If the residues are present you must take additional steps.
How to clean an Oily Tank or Drum?
If the tank or drum is oily with petrol, diesel, or grease must use the boiling or steaming methods. When the tank is immersed in the boiling water completely, it is essential to add a proprietary degreasing detergent (Not a household detergent) to the water.
Commercially available products usually contain substances metasilicate such as sodium hydroxide (Caustic soda) or (Sodium carbonate soda) and emulsifying agents.
Strong alkalis Such as caustic soda will attack Aluminum and its alloys producing hydrogen. If you are cleaning such a tank or container then use one of the weaker alkaline cleansers.
Checking after Cleaning-
After cleaning the inside of the containers must be checked for residual vapors or solids.
During welding surface becomes hot and any oil or grease present will be vaporized, forming an explosive atmosphere.
If flammable vapors or sludge deposits are detected in the vessels after cleaning, you must repeat the cleaning or make sure the vessel is inert before you carry out hot work.
You can also use one substance named trichloroethylene to wash out stubborn sludge but this substance has a narcotics effect and must be used with caution and only well-ventilated area are allowed.
If you follow this method it must be followed by a further, Cycle of steaming because of the possible fire or toxic hazards.
Q45. Explain the procedure of safety measures and components used for Hydrotest.
Ans- The procedure of the Hydro test involves filling the test system with a liquid (Water) and pressurizing it to a specified test pressure:-
1) First, fill the pipe little by little, previously calculating the amount of water that needs to fill the line.
2) Expel the air from the line when the filling is going on since its presence can cause excessive pressure.
3) Removing the water or liquid in the appropriate places that do not affect the environment
Safety measures for hydro tests are:-
- Barricade the hydraulic test area and provide warning signage to prevent unauthorized entry of personnel
- Use only calibrated pressure gauges and pressure relief valves.
- The rating of fittings, gauges, vents, and valves must be adequate for the test pressure.
- Mani fold also should be calibrated by 3rd party.
The following components are used for the hydro test:-
- Hydrostatic test pumps
- Test manifolds
Q46. What are the 3C’s of an Emergency?
Ans– The Three C’s of Emergency are:-
Check means checking for anything unsafe. If the emergency is surrounded by danger, assistance may be needed. Rushing into a scene without taking in present dangers may lead to more harm for yourself or others.
For example, if a car wreck happens in a high-traffic area or there is someone in need of help in a fire, you will need to seek assistance. Check the scene before entering it. Take the evolution of the scene. Next check if the victim is breathing. You may need to give specific care such as CPR.
In emergencies, it’s important to call 911 immediately. As a first responder, act right away to get help from professionals. Inspect the scene, and gather needed information—check for breathing and pulse from any victims, and any other helpful information. Provide correct information for local authorities and get them involved as soon as possible.
After checking the scene and calling for help, provide care until medical professionals arrive on the scene. Monitor the victim’s breathing. You may need to stop bleeding or perform CPR. Follow the circulation-airway-breathing of first aid.
Q47. What is the precaution during scaffolding erection?
Ans- The following precautions are required during scaffolding erection:-
- Scaffolding erection and dismantling should be done under the supervision of a
COMPETENT PERSON (Scaffolding Supervisor).
- The Red Tag means Danger “do not use” and Green Tag means “scaffold completely ready
for use” when completed.
- The gap between boards/planks should be 1 inch (25mm).
- The top guardrail, mid rail, and toeboard should be provided.
- Guard rails and Toeboards shall be fitted to the inside of standards.

emergency equipment, operating area equipment, instrument and control panels,
ladders, stairways, etc.
- The scaffold platform opening should be secured with a guardrail and a sign board.
- All scaffolding couplers should be tightened properly.
Q48. What is the difference between Calibration and 3rd party Certification?
Ans- Third-party Certification simply involves verifying the performance accuracy of a machine at a given point in time. Calibration involves making adjustments to the machine and doing whatever is necessary to correct geomatic errors and restore the machine to its original performance accuracy parameters.
Relevant information about the calibration, such as equipment used, environmental conditions, signatories, date of calibration, certificate number, the uncertainty of the calibration, etc.
Q49. When and how long should an eyewash station be flushed?

Q50. What is the difference between a fire blanket and a tarpaulin?
Ans- A fire blanket is a specially made cloth that is used to cover the fire while tarpaulin is to cover goods or materials from Dust or water.
Q51. What can be the reason for insulation from a safety point of view? What are the health hazards?
Ans- From a safety point of view, Industrial applications piping can be operating at extremely low or high temperatures. There is a potential danger of touching the piping if it is too hot or too cold. Insulation protects workers against burns from inadvertently coming in contact with the piping. Insulation brings a piping and valve system into a safe range for workers.
The second safety reason is NOISE. Noise has a sneaky way of traveling through the pipework. insulating the piping and valves is a valid method to reduce noise. It acts as an acoustic decoupler by preventing noise transfer when pipes pass through a fixed structure such as a floor or wall and lowers the noise of the materials moving through the systems. Hope you understand
1) Improperly Installed Attic Insulation Can Make You Sick, They have a sickening odor that can make people ill after long exposure.
2) Insulation includes fiberglass, a common plastic that contains resins and fibers. As a result, people who handle or are exposed to this insulation can breathe in tiny bits of glass. After a while, those bits can get stuck in a person’s lungs, leading to respiratory problems.
Q52. What is the difference between the HSE manual and the HSE plan?
Ans- The HSE Plan can be referred to as an HSE management program aimed to achieve any specific HSE objective and target/goal and should essentially define the objective. The HSE plan is all about the HSE activity (what you wish to achieve), program (what you plan to do), Action Plan (how it will be accomplished), responsibilities of persons at different levels, and the time frame within which the goal is to be achieved.
The HSE manual is simply a description of your Environment and OHS management system that contains the project-related information, HSE management structure, and issues. It describes risks and hazards related to the job, policy, arrangements, operational control measures & safe work procedures. The HSE manual provides guidelines for the effective management of the overall HSE system.
Q53. When can harnesses become deadly?
Ans- Harnesses can become deadly whenever a worker is suspended for durations over five minutes in an upright posture, with the legs relaxed straight beneath the body.
Q54. Difference between ISO 450001 and OHSAS 18001?
Ans- The now-defunct OHSAS 18001 was mainly focused on managing occupational health and safety hazards and issues related to them. However, ISO 45001 primarily focuses on the interaction between the working environment and the organization. This helps to minimize or eliminate the chance of any hazard.
The new ISO 45001:2018 standard is a process-based certification while the old OHSAS 18001 is a procedure-based certification. The first one focuses primarily on why the hazard happens rather than solely concentrating on the solution part.
The OHSAS 18001 is not dynamic, but the new ISO 45001 truly is. Besides addressing all the OH&S issues of any organization, it also gives it the much-required confidence in safety management for efficient productivity and improved working conditions for all the workers.
The OHSAS 18001 certification primarily focuses on the occupational risk of any organization while the ISO 45001 focuses on both the risk and opportunities. Doing so, not only eliminates the chance of future hazards and also finds opportunities to improve the overall safety standard.
OHSAS 18001 did not ever include the views of interested parties of any organization. However, the new ISO 45001:2018 contains all the aspects. With that inclusion, it not only creates the engagement of all the parties but also creates a better working environment.
Q55. What are line break activities, their hazards, and which permit is required?
Ans- Line breaking is the activity of the opening of a pipe, line, or duct that contains or has contained material capable of causing injury by hydrocarbon. Now the question is what’s the role of safety in the above-mentioned activities? Our role is to guide workers about potential hazards available inside pipes or ducts etc.
There are the following hazards in line-breaking activities in the hazardous pipelines:-
- Stored energy
- A hazardous substance refers to any chemical. Those are Toxic, Corrosive, or reactive state Human sensitivity and/or Explosive or combustible state
- Temperature less than 14° F (-10° C) cold
- Temperature more than 140° F (60° C) hot
Flammable or combustible materials, oxidizing materials, carcinogens, very cold materials, very hot materials, (as I mentioned temperature above) pressurized fluids and gases, steam, strong vacuum, etc.
A line Break Permit is Required for this type of activity, where pipework requires opening up and where hazardous contents may leak or where residual deposits may be present.
