Introduction To Oil and Gas Safety Health Environment
Dear readers,
Let learn new things about the oil and gas sector.
As we all know, safety is the heart and slogan of oil and gas industry.
So, Why HSE is so Important In Oil and Gas?
Here are reasons.
- The oil and gas industry Involve high risk activities, including exploration ,drilling production, processing of highly flammable and exclusive material.
- Massive man power, heavy-complicated-expensive machinery and extensive support system.
- High investment(Could be >1 Billion USD) and long pay back period (Could be >10 years)
- Strategic and vital environment
- Remote and harsh environment
- Accident consequences could be catastrophic in term of number of casualties, environment pollution, lost of investment, and reputation damage.

UNDERSTANDING HAZARD AND RISK
O A hazard is any source having potential to damage, harm, or adverse health effects on something or someone under certain condition at work.
O A hazard can cause harm or adverse effects (to individual as health effects or property losses)
Example :
| Source | Hazard | Harm Caused |
| Object | Knife (sharp edge) | Cut |
| Material | Benzene | Leukemia |
| Energy source | Electricity | Electrocution |
| Condition | Wet floor | Slip, fall |
| Process | Welding | Metal fume fever |
RISK
O Risk is the chance or probability that a person will be harmed or experience an adverse health effect if exposed to a hazard. It may also apply to situations with property or equipment loss.
O Risk is the combination of likelihood and severity of a specified hazardous event occurring. In mathematical term, risk can be calculated as :
RISK = LIKELIHOOD X SEVERITY, where :
O Likelihood is an event likely to occur within specific period or in specified circumstances
O Severity is the outcome from an event such as injury or health of people, or damage to property, or environment pollution, or any combination of those.
