1. What is Safety?

Safety can be defined as a state in which the risk of being harmed, injured or sustaining losses is kept at a tolerable level. It encompasses policies, protocols and controls designed to safeguard the people, the structures and the environment in an oil and gas facility from possible dangers associated with the refinery processes.

Why it’s asked: Employers also like to ask this question to make sure that you comprehend the concept of safety, which is believed to be a leading cause of accidents and incidents.

2. What is the Role of a HSE Officer?

A Health, Safety, and Environment (HSE) Officer’s primary responsibility entails the formulation, execution, and review of policies, processes and procedures that work towards maintaining a safe environment. This will include doing risk management, doing safety checks, educating personnel and making sure that safety regulations are obeyed.

Why it’s asked: This question gauges your understanding of the responsibilities associated with the position and your ability to ensure safety in a high-risk environment like an oil and gas refinery.

3. What Are the Common Hazards in an Oil & Gas Refinery?

Common hazards in an oil and gas refinery include fire and explosions, toxic gas releases (like H2S), electrical hazards, slips, trips, and falls, confined spaces, and exposure to harmful chemicals.

Why it’s asked: Interviewers want to know if you can identify potential dangers in the workplace and understand how to manage these risks effectively.

4. H2S Gas: What is it exactly?

Hydrogen Sulfide (H2S) is a poisonous, flammable gas that can be found in any oil and gas refinery. It is colorless but in smaller concentrations appears to have the odor of rotten eggs. However, high levels can be fatal.

5. What Are the Safety Measures for H2S?

H2S safety measures involve close watching of the level of H2S at the site, ensuring use of protective gear such as gas masks and varieties of PPE, proper room ventilation, and preparation of contingency plans.

Why it’s asked: This is the part in which you understand the necessity of safety protocols and potential exposure to hazardous materials.

6. What Should You Do When an H2S Gas Alarm Sounds?

In case of an H2S gas alarm, workers are required to put on their respirator immediately, leave that working place, and go to a safe area away from the wind. The situation should then be reported to the safety team for further action.

Why it’s asked: Employers would want to confirm that you are aware of what steps to take and in what time should these actions be taken if the hazard in the form of a gas leakage arises.

7. What is TLV?

The term TLV indicates Threshold Limit Value is the highest concentration of the chemical substance that a worker may be exposed to without developing negative health effects, only for an 8-hour duration.

The TLV for Benzene is 0.5 ppm over an 8-hour period workday. Violation of this limit could result in the risk of adverse effects such as Cancer.

Why it’s asked: Why do you need to know about TLVs in general? It is because they emphasize ways on how to avoid overexposure to dangerous chemicals at work.

8. What is TWA?

TWA, short for Time Weighted Average refers to the average amount on a certain substance that was absorbed for a certain time frame, usually an 8-hour working day. Besides, TWA is used in order to protect workers from the effect of harmful substances over a period of time.

Example: If a worker is exposed to 2 ppm of a solvent for 4 hours and 1 ppm for the remaining 4 hours of their shift, the TWA would be 1.5 ppm. This helps ensure that the worker’s overall exposure remains within safe limits.

Why it’s asked: This notion is very much important when determining the risks of long term exposures and insuring the rules of health protection at work are followed.

9. What is STEL?

An abbreviation of Short-Term Exposure Limit, STEL presents the maximum level of a hazardous substance which can be inhaled by the employee within brief intervals (usually not more than 15 minutes) without his being irritated, damaged in tissue or drugs effects, or whatsoever.

Example: Ammonia STEL limit is 35 ppm. This indicates that, workers should be limited to concentrations lower than 35 ppm for at most 15 minutes within which health conditions that allow individuals to breathe without irritating their lungs are supposed to be sustained.

Why it’s asked: This is important because the STEL needs to be determined when short time limits or short term exposures to hazard-favorable conditions occur.

10. What is IDLH?

The acronym IDLH which means Immediately Dangerous to Life or Health is often confused with the term defined in other classifications. Stating Situations where a person is exposed to a harmful substance for single minutes or less has a high probability of succumbing to the harmful substance nearly or totally unprotected.

Example: For example, the IDLH level for Carbon monoxide (CO) is 1200 ppm. Once workers are heady exposed to CO concentration at this level, there is no alternative to safe relocating from this zone because the mortal danger level is extremely high, e.g. the health effects from even single minutes stay would be severe.

Why it’s asked: Such questions are often posed by the employers in order to know if you are able to act where action is imperative to saving lives.
