Study Notes

Terms and Definitions

Body mechanics: Using the body efficiently to maintain balance and motion.
Carpal tunnel syndrome: A condition caused by nerve compression in the wrist leading to weakness and pain.
Circuit breaker: A device that interrupts electrical flow to prevent overload.
Flammable/Combustible: Terms describing materials that can ignite at specific temperature thresholds; flammable ignites easily, while combustible ignites at higher temperatures.
Ergonomic: Design approach ensuring equipment and workspace promote safety and efficiency.

Developing a Good Safety Attitude

Adopt a mindset that prioritizes safety to prevent accidents and save lives.
Stay focused on tasks and avoid distractions that can lead to accidents.
Avoid shortcuts; thoroughness ensures safety and quality of work.
Proactively prioritize tasks to manage time efficiently and address critical issues first.

- Blue for health hazards, red for fire hazards, yellow for reactivity, and black for special hazards.

Methods of Hazardous Material Entry into the Body

Ingestion: Swallowing harmful substances, like alcohol.
Absorption: Chemicals entering through skin contact, such as cleaners.
Inhalation: Breathing in harmful gases or vapors, such as anesthetics.

Principles of Body Mechanics

Good body mechanics involve maintaining proper posture and using proper lifting techniques to reduce the risk of injury.
