HSE officer interview questions and answers

Q. What is H2S?

Ans. H2S gas is the most common toxic and flammable gas in oil and gas

refinery, it produced by the decomposition of organic material and by

processing of chemical products in refinery.

H2S gas also Hydrogen sulphide smell very bad like a rotten egg at concentration of

1ppm, above 1ppm it cannot be smell by nose.

It is highly flammable between 4.3% to 45.5% by volume in air.

H2S gas is a colorless gas.

It is heavier than air.

Highly soluble in water.

It produced sulfur dioxide (CO2) by burning which is also a highly toxic and

colorless gas.

Its permissible exposure limit is 10ppm, at 10ppm person can exposed for 8

hours without any adverse health effect.

TLV-TWA of H2S – 10 PPM

STEL of H2S – 15 PPM

IDLH of H2S – 100 PPM

HSE officer interview questions

Note: - at 10ppm person can expose to h2s for 8 hours without any respiratory

PPEs, but no work will be allowed at 100ppm of h2s.

Q. Different in CO & CO2.

Ans. Carbon Monoxide (CO) & Carbon dioxide (CO2) both gases are colourless & odourless but carbon monoxide is flammable, CO2 above 5000 PPM and CO above 35 PPM is harmful to humans.

Q. What is TWA?

Ans. Threshold Limit Value (TLV) means the concentration of hazardous

substance in air, in which workers can be exposed day after day for a working

lifetime without adverse long term health effects.

Q. What is STEL?

Ans. Short Term Exposure Limit (STEL) means the maximum concentration of a

chemical or toxic gas at which workers can exposed for up to 15 minutes,

without any adverse health effects.
