Safety Flashcards
Type of electrical shock that is introduced inside the body that can be fatal at currents as low a .01 mA.
Microshock
Explosive vaporization of a metal conductor caused by an electrical short
Arc flash
Condition in the environment that could cause injury or death
Hazard
Likely hood and consequence of a hazard to cause harm.
Risk
What are the four behaviors that contribute to the likelihood and consequences of a hazard causing harm?
Rushing
Fatigue
Complacency
Frustration
What are the four types of hazard mitigation used to reduce the risk of an activity?
Engineering
Administrative
PPE
Behavior
What are some examples of administrative controls to reduce risk?
Lock-out, Tag-out procedures
Inspection checklists

Steel toed boots
What are examples of behavior controls used to reduce risk?
Behavior based observations
Hazard identification training
Safety meetings
Electric shock causes
