What does HIRA stands for
- A.
Hazard Identification & Risk Assessment
- B.
Hazard initial Risk Analysis
- C.
Hazard Identification & Record Analysis
- D.
Hazard initial Risk Assessment
Correct Answer
A. Hazard Identification & Risk AssessmentExplanation
The correct answer is Hazard Identification & Risk Assessment. HIRA is an acronym that stands for Hazard Identification & Risk Assessment. This process involves identifying potential hazards in a given environment or situation and assessing the associated risks. It is an essential step in ensuring the safety and well-being of individuals and preventing accidents or incidents. By identifying hazards and assessing their risks, appropriate measures can be taken to control or mitigate these risks and prevent potential harm or damage.Rate this question:

Risk Priority Number (RPN) for Substantial Risk is between
- A.
73 to 130
- B.
131 to 250
- C.
37 to 72
- D.
251 to 625
Correct Answer
B. 131 to 250Explanation
The Risk Priority Number (RPN) for Substantial Risk falls between 131 to 250. This means that when assessing the risk level of a particular situation, if the RPN falls within this range, it indicates a significant level of risk that requires immediate attention and action. RPN is calculated by multiplying the severity, occurrence, and detection ratings of a risk, and a higher RPN indicates a higher level of risk. Therefore, an RPN between 131 to 250 signifies a substantial risk that needs to be addressed promptly.Rate this question:

What does ALARP stands for
- A.
As Less as Reasonable Practicable
- B.
As low as Reasonable Permissible
- C.
As low as Practicable Reasonable
- D.
As low as Reasonably Practicable
Correct Answer
D. As low as Reasonably PracticableExplanation
ALARP stands for "As low as Reasonably Practicable." This principle is commonly used in risk management to determine the acceptable level of risk or harm in a given situation. It means taking all reasonable steps to minimize risks and hazards to the lowest possible level, considering factors such as feasibility, cost, and available resources. The aim is to achieve a balance between the level of risk reduction and the effort or cost required to achieve it.Rate this question:

Road Safety warning signs should be located approximately ________ meters in advance of Hazard
- A.
75 – 100 meters
- B.
25 – 50 meters
- C.
50 – 75 meters
- D.
100 – 125 metes
Correct Answer
A. 75 – 100 metersExplanation
Road safety warning signs should be located approximately 75-100 meters in advance of a hazard. This distance allows drivers enough time to react and adjust their speed accordingly to ensure their safety. Placing the signs too close to the hazard may not give drivers enough time to respond, while placing them too far away may not effectively communicate the potential danger ahead. Therefore, the optimal distance for road safety warning signs is between 75 and 100 meters.Rate this question:

Why grease or oil shall not be used in Oxygen cylinder valves
- A.
Because it will reduce the flammability of oxygen
- B.
Because it will easily actuate the regulator
- C.
Oxygen burst once it get in touch with oil or grease
- D.
None of the above
Correct Answer
C. Oxygen burst once it get in touch with oil or greaseExplanation
Grease or oil should not be used in oxygen cylinder valves because when oxygen comes into contact with oil or grease, it can cause a chemical reaction that leads to a burst or explosion. This is due to the highly reactive nature of oxygen, which can react with flammable substances and cause combustion. Therefore, it is important to keep oxygen cylinders and valves clean and free from any oil or grease to ensure safety.Rate this question:

Allowed frequency of manual lifting of objects
- A.
2 lifts per 10 minutes
- B.
3 lifts per 10 minute
- C.
2 lifts per 5 minutes
- D.
3 lifts per 5 minutes
Correct Answer
A. 2 lifts per 10 minutesExplanation
The allowed frequency of manual lifting of objects is 2 lifts per 10 minutes. This means that a person is permitted to lift objects twice within a 10-minute time frame. This restriction is likely in place to prevent excessive strain on the body and reduce the risk of injury from repetitive lifting tasks.Rate this question:

Class A Petroleum is having a flash point
- A.
Between ≥ 23 ° C < 65 ° C
- B.
Below < 23° C
- C.
Between of ≥ 65 ° C < 93 ° C
- D.
None of above
Correct Answer
A. Between ≥ 23 ° C < 65 ° CExplanation
The flash point of Class A Petroleum is between 23 °C and 65 °C. This means that the petroleum will not ignite or produce a flame when exposed to an open flame or heat source below 23 °C. However, it will ignite and produce a flame when exposed to an open flame or heat source above 65 °C. Therefore, the correct answer is "Between ≥ 23 °C < 65 °C".Rate this question:

According to OSHAS HAZCOM a gas in cylinder is called compressed gas if
- A.
If absolute pressure is greater than 1 bar at 21 degree celcius
- B.
If absolute pressure is greater than 40 psi at 21 degree celcius
- C.
If absolute pressure is greater than 1 bar at 30 degree celcius
- D.
If absolute pressure is greater than 40 psi at 30 degree Celcius
Correct Answer
A. If absolute pressure is greater than 1 bar at 21 degree celciusExplanation
According to OSHAS HAZCOM, a gas in a cylinder is called a compressed gas if the absolute pressure is greater than 1 bar at 21 degrees Celsius. This means that the gas inside the cylinder is under high pressure, which is necessary for it to be classified as a compressed gas. The specific temperature and pressure conditions mentioned in the other options do not meet the criteria for classifying a gas as compressed.Rate this question:

While transporting hazardous material, driver must carry
- A.
TREM card
- B.
MSDS
- C.
RCFA
- D.
Explosive meter
Correct Answer
A. TREM cardExplanation
When transporting hazardous materials, it is important for the driver to carry a TREM card. A TREM card, also known as a Transport Emergency Card, provides essential information about the hazardous material being transported, including its identification, potential hazards, and emergency response procedures. This card helps to ensure that the driver and emergency responders are aware of the necessary precautions and actions to take in case of an accident or spill during transportation. The MSDS (Material Safety Data Sheet) provides detailed information about the specific hazardous material, RCFA (Root Cause Failure Analysis) is a problem-solving technique used in industrial settings, and an explosive meter is not directly related to transporting hazardous materials.Rate this question:

While entering LPG yard storage, vehicle silencer must have
- A.
Flashback arrestor
- B.
Flame arrestor
- C.
Spark arrestor
- D.
All of the above
Correct Answer
C. Spark arrestorExplanation
A spark arrestor is necessary while entering LPG yard storage to prevent any sparks or flames from the vehicle's silencer. This is important because LPG is highly flammable and any ignition source can cause a fire or explosion. A spark arrestor is designed to trap and extinguish sparks, thus reducing the risk of ignition and ensuring safety in the storage area. Additionally, a flashback arrestor and flame arrestor may also be required in certain situations, but the spark arrestor is specifically mentioned in this context.Rate this question:

With increase in speed, the angle of vision
- A.
Remains same
- B.
Increases proportionately
- C.
Depends on type of the vehicle
- D.
Reduces proportionately
Correct Answer
B. Increases proportionatelyExplanation
As the speed increases, the angle of vision also increases proportionately. This means that as the speed of a vehicle increases, the range of vision expands, allowing the driver to see a wider area in front of them. This is important for safety reasons, as it allows the driver to have a better awareness of their surroundings and potential hazards on the road.Rate this question:
