Questions and Answers

1.

Lowest temperature of flammable liquid at which it gives sufficient vapour to form ignitable mixture.
- A.
  
  Ignition point
- B.
  
  Flammable Point
- C.
  
  Flash point
- D.
  
  Explosive limit
Correct Answer
C. Flash point

Explanation
The flash point is the lowest temperature at which a flammable liquid can emit enough vapor to form an ignitable mixture with air. This is the temperature at which the liquid can produce a flash of fire when exposed to an ignition source. The flash point is an important safety parameter as it helps determine the potential for fire and explosion hazards.

Ladder to wall ratio is
- A.
  
  1:1
- B.
  
  1:2
- C.
  
  1:3
- D.
  
  1:4
Correct Answer
D. 1:4

Explanation
The correct answer is 1:4. This means that for every 1 unit of ladder height, there are 4 units of wall height. This ratio indicates that the ladder is leaning at a steeper angle compared to the wall. A 1:4 ratio suggests that the ladder is inclined at a 75-degree angle from the ground, making it more vertical and less steep. This ratio provides stability and ensures that the ladder is securely placed against the wall.

The purpose of Electric Fuse is to arrest
- A.
  
  Electric Shock
- B.
  
  Current flow
- C.
  
  Excess Voltage
- D.
  
  Low voltage
Correct Answer
C. Excess Voltage

Explanation
An electric fuse is designed to protect electrical circuits from excessive voltage. When the voltage exceeds a certain limit, the fuse will melt and break the circuit, preventing further damage to the electrical components. This is important because excessive voltage can cause overheating, fires, and damage to appliances or devices connected to the circuit. By breaking the circuit, the fuse acts as a safety measure to prevent these potential hazards.

LPG gas smells because of
- A.
  
  Ethyl Mercaptan
- B.
  
  Butyl Mercaptan
- C.
  
  Methyl Mercaptan
- D.
  
  Non of them
Correct Answer
C. Methyl Mercaptan

Explanation
Methyl Mercaptan is the correct answer because it is a chemical compound that is added to LPG gas to give it a distinctive smell. LPG gas itself is odorless, but the addition of Methyl Mercaptan allows people to easily detect gas leaks by the strong and unpleasant odor it produces.

Hearing Protection shall be worn when noise level exceeds
- A.
  
  50 dB
- B.
  
  60 dB
- C.
  
  70 dB
- D.
  
  80 dB
Correct Answer
D. 80 dB

Explanation
Hearing protection should be worn when the noise level exceeds 80 dB. This is because noise levels above 80 dB can cause damage to the ears and lead to hearing loss over time. Therefore, it is important to wear hearing protection in environments where the noise level exceeds this threshold to prevent any potential harm to the ears.

Which Body Part affects due to improper Manual Handling
- A.
  
  Legs
- B.
  
  Ribs
- C.
  
  Spinal Cord
- D.
  
  Shoulders
Correct Answer
C. Spinal Cord

Explanation
Improper manual handling can result in strain or injury to the spinal cord. The spinal cord is responsible for transmitting signals between the brain and the rest of the body, and any damage to it can lead to serious consequences. Lifting heavy objects incorrectly or using improper techniques can put excessive strain on the spinal cord, leading to back pain, herniated discs, or even more severe conditions such as spinal cord compression. Therefore, it is important to practice proper manual handling techniques to protect the spinal cord and prevent potential injuries.

For electrical fire what type of fire extinguisher is appropriate for use ?
- A.
  
  CO2.
- B.
  
  DCP
- C.
  
  Foam type
- D.
  
  Chemical type
Correct Answer(s)
A. CO2.
B. DCP

Explanation
CO2 (carbon dioxide) fire extinguishers are appropriate for use in electrical fires because they do not conduct electricity. When CO2 is discharged, it displaces oxygen, suffocating the fire. DCP (dry chemical powder) extinguishers are also suitable for electrical fires as they create a barrier between the fuel and oxygen, interrupting the combustion process. Foam type and chemical type extinguishers, on the other hand, are not recommended for electrical fires as they can conduct electricity and potentially cause harm to the user.

In three core cable, what is the color code of earthling wire?
- A.
  
  Green
- B.
  
  Red
- C.
  
  Blue
- D.
  
  Black
Correct Answer
A. Green

Explanation
The color code for the earthling wire in a three core cable is green. This is a standard color used in electrical wiring to indicate the grounding or earthing connection. The green wire is connected to the earth to provide a safe path for electrical currents in case of a fault or surge. It helps to protect against electric shock and ensures the safe operation of electrical devices.

  Risk Assessment
- B.
  
  Job safety Analysis
- C.
  
  Audit
- D.
  
  HSE Plan and Procedures
Correct Answer
C. Audit

Explanation
An audit is a systematic, independent evaluation that assesses whether a health, safety, and environment management system complies with planned arrangements and if it is implemented effectively. It also determines if the system is suitable to fulfill the company's health, safety, and environmental policy and objectives. Therefore, an audit is the most appropriate choice for evaluating the effectiveness and compliance of the management system in relation to health, safety, and environmental concerns.
