Study Notes

The injury pyramid consists of four levels: death, permanent total disability, permanent partial disability, and first aid cases
The majority of incidents result in first aid cases, with fewer incidents resulting in more severe outcomes

Horseplay: engaging in playful but potentially dangerous behavior, such as roughhousing or joking around, while on the job
Not following lockout/tagout procedures: failing to properly shut down and lock out equipment during maintenance, leading to potential injury or death

Oxygen deficiency: insufficient oxygen in the confined space, which can lead to asphyxiation
Toxic substances: presence of harmful gases or chemicals in the confined space, which can cause illness or death

Release: sudden release of flammable vapor into the air
Dispersion: the vapor cloud spreads and mixes with air
Ignition: the vapor cloud is ignited, often by an ignition source such as an open flame or spark
Explosion: the rapid expansion of gases, resulting in a blast wave and heat

The process of identifying and evaluating potential hazards in the workplace
Identifying hazards allows for the implementation of controls to mitigate or eliminate the risk of injury or illness

Job Safety Analysis (JSA): a systematic approach to identifying and mitigating hazards associated with specific tasks or jobs
Hazard and Operability Study (HAZOP): a structured approach to identifying potential hazards and operational problems in a process or system
