Red Card Environmental Health & Safety 5

Question 1

What is the primary physiological mechanism by which heat stroke differs from heat exhaustion?

Accepted Answer

In heat stroke the body's thermoregulation fails and sweating stops, causing core temperature to rise dangerously

Answer

Heat stroke represents a failure of the body's cooling system — sweating ceases and core temperature can exceed 104°F, causing organ damage and death if untreated.

Question 2

When conducting a Lookout, Communications, Escape routes, Safety zones (LCES) briefing, who is responsible for verifying that all crew members understand the plan?

Accepted Answer

The crew supervisor or Division Supervisor before committing the crew to the assignment

Answer

The crew supervisor must brief and verify crew understanding of LCES before deploying them on any assignment.

Question 3

What environmental impact consideration must crews follow when establishing spike camps in wilderness areas?

Accepted Answer

Minimum impact practices must be used, including no-trace camping and avoiding sensitive riparian areas

Answer

Minimum impact camping practices are required on wildland fires to protect wilderness resources, including soil, water, and vegetation.

Question 4

A sudden wind shift on a wildland fire is most dangerous because it:

Accepted Answer

Can instantly turn the black (burned area) into the green (unburned fuel), trapping firefighters working the line

Answer

A wind shift can place firefighters who were safely in the black directly in the path of advancing fire from a new direction with no warning.

Question 5

Which of the following actions best reduces the risk of carbon monoxide (CO) poisoning at a fire camp with generator use?

Accepted Answer

Positioning generators downwind of sleeping areas and never operating them inside enclosed spaces

Answer

Generators must always be operated outdoors and downwind of sleeping or working areas because CO is odorless and can be lethal in enclosed or semi-enclosed spaces.
