Hazard Identification & Assessment Flashcards

Which factor is MOST critical when assessing the hazard level of a crowd that is becoming hostile?

Answer: Crowd size, density, and emotional state

Crowd size, density, and emotional state directly determine the potential for violence and the officer's ability to maintain control.

A subject is found unresponsive in a vehicle with the engine running in a closed garage. What is the PRIMARY chemical hazard present?

Answer: Carbon monoxide poisoning

Carbon monoxide from engine exhaust is colorless and odorless, making it a deadly and invisible chemical hazard.

When assessing a suspicious package left in a public area, which characteristic is LEAST reliable as a sole indicator of danger?

Answer: Package size and weight

Size and weight alone are unreliable indicators; improvised devices can be very small or very heavy without being dangerous.

In hazard assessment, 'likelihood' refers to which component of risk?

Answer: The probability that a hazard will result in harm

Likelihood measures the probability of occurrence, which combined with severity determines overall risk level.

An officer is dispatched to a report of a person with a knife. Which environmental factor MOST increases officer hazard?

Answer: Confined space with limited exit routes

Confined spaces remove the officer's ability to create reactionary distance, dramatically increasing the danger from an edged weapon.

What is 'secondary device' awareness in the context of explosion scenes?

Answer: The possibility of a second explosive device targeting first responders

Secondary devices are intentionally placed to injure or kill first responders who respond to the initial explosion.

Which of the following best describes a 'dynamic hazard' as opposed to a 'static hazard'?

Answer: A hazard that changes or moves over time, such as a fleeing armed suspect

Dynamic hazards evolve over time and require continuous reassessment, unlike static hazards that remain constant.
