Who is the approver for the Interlock Bypassed for a duration of less than 24 hrs?
- A.
Plant HOD
- B.
Shift Incharge
- C.
Production Manager
- D.
None of the above
Correct Answer
A. Plant HODExplanation
The Plant HOD is the approver for the Interlock Bypassed for a duration of less than 24 hrs. This means that the Plant Head of Department has the authority to approve the bypassing of the interlock system, which is a safety mechanism used to prevent accidents or malfunctions. The other options, Shift Incharge and Production Manager, do not have the same level of authority as the Plant HOD in approving such bypasses. Therefore, the correct answer is Plant HOD.Rate this question:

Prior to entering a confined space, all Mechanical Hazards must be:
- A.
Controlled by locks and tags
- B.
Identified
- C.
Painted red
- D.
None of the above
Correct Answer
A. Controlled by locks and tagsExplanation
Before entering a confined space, it is important to control all mechanical hazards by using locks and tags. This ensures that any machinery or equipment within the confined space is properly shut down, isolated, and secured to prevent accidental activation or release of energy. Locks and tags provide a visual indication that the equipment is not to be operated and serves as a safety measure to protect workers from potential harm. Identifying the hazards alone is not sufficient; controlling them through locks and tags is necessary to ensure a safe working environment. Painting the hazards red is not a recognized or effective method of hazard control.Rate this question:

Work at height means:
- A.
To work above 3.5 Mtr. from floor level
- B.
To work above 1.0 Mtr. from floor level
- C.
To work above 1.5 Mtr. from floor level where permanent working platform is not there
- D.
None of the above
Correct Answer
C. To work above 1.5 Mtr. from floor level where permanent working platform is not thereExplanation
Work at height refers to working at a height of more than 1.5 meters from the floor level when there is no permanent working platform available. This means that individuals are required to perform tasks at an elevated position where there is no fixed structure or platform to support them. It emphasizes the need for safety precautions and measures to prevent falls or accidents in such situations.Rate this question:

Which is an appropriate anchor point for the lanyard of full-body harness?
- A.
Sprinkler water pipeline
- B.
Permanent Structure
- C.
Impulse tube
- D.
None of the above
Correct Answer
B. Permanent StructureExplanation
An appropriate anchor point for the lanyard of a full-body harness is a permanent structure. This is because a permanent structure, such as a sturdy beam or column, is designed to support heavy loads and is less likely to fail or collapse under the weight and force applied by the harness. Using a permanent structure as an anchor point ensures the safety and stability of the person wearing the harness, reducing the risk of falls or accidents. Anchoring the lanyard to a sprinkler water pipeline or impulse tube may not provide the necessary strength and stability required for fall protection.Rate this question:

Shell of Helmet: The hard smoothly finished material that provides the general outer form of the helmet is made by which material.
- A.
Glass
- B.
Suitable plastic
- C.
HDPE (High density poly ethylene)
- D.
All of above
Correct Answer
C. HDPE (High density poly ethylene)Explanation
The correct answer is HDPE (High density poly ethylene). HDPE is a suitable material for making the hard smoothly finished shell of a helmet. It is a strong and durable plastic that provides protection and impact resistance. Glass is not a suitable material for making the helmet shell as it is fragile and can easily break. While suitable plastic can be used, HDPE is specifically mentioned as the correct answer, indicating that it is the preferred material for this purpose.Rate this question:

In SCBA set Warning whistle should start blowing at:
- A.
10 bars
- B.
45 bars
- C.
200 bars
- D.
0 bars
Correct Answer
B. 45 barsExplanation
The correct answer is 45 bars because in an SCBA set, the warning whistle is designed to start blowing when the pressure inside the cylinder reaches 45 bars. This serves as an alert to the user that the air supply is running low and they need to exit the hazardous environment or replace the cylinder to ensure their safety.Rate this question:
-
- 14.
Which type of Air compressor to be used for SCBA Set filling?
- A.
Non-lubricated Air compressor
- B.
Lubricated air compressor
- C.
Both
- D.
None of above
Correct Answer
A. Non-lubricated Air compressorExplanation
A non-lubricated air compressor should be used for filling SCBA (Self-Contained Breathing Apparatus) sets. This is because the compressed air that is used to fill the SCBA sets should be free from any contaminants, including oil or lubricants. Lubricated air compressors use oil to lubricate the moving parts, which can contaminate the compressed air. Therefore, a non-lubricated air compressor is the appropriate choice to ensure the purity of the compressed air used for filling SCBA sets.Rate this question:

How is Risk calculated?
- A.
Exposure x Severity x Probability
- B.
Exposure x Hazard
- C.
Exposure x Severity
- D.
None
Correct Answer
A. Exposure x Severity x ProbabilityExplanation
Risk is calculated by multiplying the three factors: exposure, severity, and probability. Exposure refers to the level of vulnerability or potential harm that exists in a given situation. Severity represents the extent of the potential consequences or damage that could occur. Probability refers to the likelihood or chance of the risk event actually happening. By multiplying these three factors together, the overall risk level can be determined, taking into account both the potential harm and the likelihood of it occurring.Rate this question:
-
- 18.
How is Hazard calculated?
- A.
Exposure x Severity x Probability
- B.
Exposure x Hazard
- C.
Exposure x Severity
- D.
None
Correct Answer
C. Exposure x SeverityExplanation
Hazard is calculated by multiplying the exposure, severity, and probability of an event occurring. This formula takes into account the level of exposure to the hazard, the potential severity of the event, and the likelihood of it happening. By multiplying these factors together, we can obtain a measure of the overall hazard level. The answer "Exposure x Severity" is correct because it only includes these two factors, while the other options either exclude the probability or include an incorrect factor.Rate this question:
