- 1.
Identify the symbol given below
- A.
No flow switches
- B.
Pressure guage
- C.
Safety relief valve
- D.
Rapture disc
Correct Answer
C. Safety relief valveExplanation
The symbol given represents a safety relief valve. This valve is used to release excessive pressure in a system to prevent any damage or explosion. It acts as a safety measure by allowing the fluid to escape when the pressure exceeds a certain limit. It is designed to automatically open and close, ensuring the system remains within safe operating conditions.Rate this question:

PVRV stand for
- A.
Pressure valve relief valve
- B.
Pressure relief valve
- C.
Pressure vaccum relief valve
- D.
None of them
Correct Answer
A. Pressure valve relief valveExplanation
The correct answer is "Pressure valve relief valve." This is because PVRV is an acronym that stands for "Pressure Valve Relief Valve." This valve is designed to relieve excess pressure in a system, preventing any potential damage or failure.Rate this question:

PVRV is fixed on the storage tank for
- A.
Their primary purpose is to protect the tank against rupturing or imploding.
- B.
Allowing gas to pass through it but stops a flame in order to prevent a larger fire or explosion
- C.
All of them
- D.
None of them
Correct Answer
A. Their primary purpose is to protect the tank against rupturing or imploding.Explanation
The correct answer is "Their primary purpose is to protect the tank against rupturing or imploding." This explanation is supported by the statement that PVRV (Pressure Vacuum Relief Valve) is fixed on the storage tank. The purpose of the PVRV is to prevent the tank from rupturing or imploding, which could occur due to excessive pressure or vacuum inside the tank. By allowing gas to pass through but stopping a flame, the PVRV helps to prevent a larger fire or explosion. Therefore, the primary function of the PVRV is to protect the tank from potential damage or failure.Rate this question:

………… device which prevents the emission of flammable debris from combustion sources
- A.
Flame arrestor
- B.
Spark arrestor
- C.
PVRV
- D.
None of above
Correct Answer
B. Spark arrestorExplanation
A spark arrestor is a device that prevents the emission of flammable debris from combustion sources. It is typically used in exhaust systems to prevent sparks or hot particles from escaping and potentially causing fires or explosions. This device is commonly found in outdoor equipment such as chainsaws, lawnmowers, and generators, where the risk of sparks and debris is high. By trapping and extinguishing these sparks, a spark arrestor helps to ensure the safety of both the equipment and the surrounding environment.Rate this question:

At LPG yard, if LPG gas leaked, for detection purposes the alarm level is set as low as practicable, preferably no higher than ……… of the lower explosion limit (LEL).
- A.
20%
- B.
10%
- C.
LEL of LPG
- D.
100% of LEL
Correct Answer
B. 10%Explanation
The correct answer is 10%. When LPG gas leaks, it is important to detect it quickly to prevent any potential explosions. Setting the alarm level at 10% of the lower explosion limit (LEL) ensures that even a small amount of leaked gas can be detected. This allows for prompt action to be taken to mitigate the leak and prevent any accidents or hazards. Setting the alarm level any higher than 10% of the LEL may delay the detection of the leak, increasing the risk of a potential explosion.Rate this question:

IP65 is waterproof
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because IP65 is not completely waterproof. IP65 is a rating that indicates the level of protection provided by an enclosure against the ingress of dust and water. IP65 means that the enclosure is dust-tight and protected against water jets from any direction, but it is not fully waterproof and cannot be submerged in water.Rate this question:

Why we should clean the packed column once in a month at RH?
- A.
Improve the quality parameter of the batch
- B.
To avoid the pressurization of the reactor
- C.
To reduce the VOC level
- D.
To avoid the red hot condition
Correct Answer
D. To avoid the red hot conditionExplanation
Cleaning the packed column once in a month at RH is necessary to avoid the red hot condition. A red hot condition can occur when there is a buildup of contaminants or impurities in the column, which can lead to excessive heat generation and potentially cause damage to the equipment. Regular cleaning helps to remove any accumulated deposits and maintain the proper functioning of the column, preventing the occurrence of a red hot condition.Rate this question:

The only hazard of batteries is battery acid that can burn skin or eyes and eat holes in clothing.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because batteries can pose other hazards besides battery acid. For example, lithium-ion batteries can explode or catch fire if they are damaged or exposed to extreme temperatures. Additionally, if batteries are not disposed of properly, they can release harmful chemicals into the environment. Therefore, it is incorrect to say that the only hazard of batteries is battery acid.Rate this question:

In combination unit of emergency shower, min. water pressure should be …
- A.
5 kgf/cm2
- B.
10 kgf/cm2
- C.
1 kgf/cm2
- D.
3 kgf/cm2
Correct Answer
C. 1 kgf/cm2Explanation
The minimum water pressure required in a combination unit of an emergency shower is 1 kgf/cm2. This pressure is necessary to ensure that an adequate amount of water flows out of the showerhead to effectively rinse off any hazardous substances or chemicals from the person using the shower. A lower pressure may result in insufficient water flow, which could compromise the safety and effectiveness of the emergency shower.Rate this question:
