Safety and Health Flashcards

What is the main purpose of an Incident Command System (ICS) at an emergency scene?

Answer: To provide a clear command structure and coordinate resources safely

ICS establishes organized command, control, and coordination, which improves firefighter safety and scene management.

What is the primary danger of heat stress (heat exhaustion or heat stroke) for firefighters?

Answer: Impaired judgment and potential collapse, which can be life-threatening

Heat stress degrades cognitive and physical function and can progress to deadly heat stroke if untreated.

When a "Mayday" is transmitted on the fireground, what does it signify?

Answer: A firefighter is in distress, trapped, lost, or injured

Mayday is the emergency call indicating a firefighter is in life-threatening trouble and needs immediate help.

Why is hearing protection important for firefighters operating power tools and riding apparatus?

Answer: Prolonged loud noise causes permanent hearing loss

Sirens, tools, and engines produce noise levels high enough to cause cumulative permanent hearing damage.

What is a key safety reason to perform a 360-degree size-up around a structure before entry?

Answer: To identify hazards, fire location, and additional access or escape points

A 360-degree walkaround reveals hazards, fire conditions, and exit options that protect the crew.

What practice helps prevent slips, trips, and falls inside a smoke-filled structure?

Answer: Maintaining contact with a wall or hoseline and probing the floor ahead

Keeping a reference (wall or hoseline) and probing ahead helps detect holes, stairs, and obstacles in zero visibility.

Why is annual medical evaluation and fitness testing important for firefighters?

Answer: The job's physical demands require detecting cardiac and health risks early

Given the cardiac and physical demands of firefighting, regular medical and fitness evaluations catch risks before they become fatal.
