F-02 Hazardous Materials Awareness Practice Test Flashcards

What is the immediate action when someone is exposed to a corrosive chemical splash?

Answer: Flush the affected area with large amounts of water for at least 20 minutes while calling 911

Immediate flushing with large amounts of clean water for at least 20 minutes is the standard first aid for corrosive chemical exposure (acid or alkali burns). Do not try to neutralize the chemical. Remove contaminated clothing while flushing. Call 911 for medical evaluation and transport.

What does the GHS (Globally Harmonized System) pictogram of a flame indicate?

Answer: The material is flammable, pyrophoric, self-heating, or a self-reactive substance

The GHS flame pictogram indicates materials that are flammable (liquids, gases, solids, aerosols), pyrophoric (ignite spontaneously in air), self-heating, or self-reactive. This is the most commonly encountered hazard pictogram on chemical products in shelters.

Why should certain cleaning chemicals never be mixed together?

Answer: Mixing incompatible chemicals can produce toxic gases, heat, fire, or explosion

Mixing incompatible chemicals can cause dangerous reactions including the production of toxic gases (bleach + ammonia = chloramine gas), generation of heat that can cause boiling and splashing, fires, or even explosions. This is a common cause of chemical injuries in buildings.

What is the proper way to handle a small gasoline spill in a shelter's maintenance area?

Answer: Ventilate the area, eliminate all ignition sources, contain the spill with absorbent material, and dispose of properly

For a small gasoline spill: ventilate the area to disperse explosive vapors, eliminate all ignition sources (including pilots lights and electrical equipment), contain the spill with approved absorbent material, place used absorbent in a covered metal container, and arrange for proper disposal.

What type of fire extinguisher should be used on a fire involving flammable liquids?

Answer: Class B rated extinguisher (CO2, dry chemical, or foam)

Fires involving flammable liquids (Class B fires) require Class B rated extinguishers such as CO2, dry chemical (ABC or BC), or foam. Water should never be used on flammable liquid fires as it can spread the burning liquid and cause the fire to grow.

What is the health hazard of carbon monoxide in a shelter?

Answer: It is an odorless, colorless gas that binds to hemoglobin, preventing oxygen transport, leading to suffocation

Carbon monoxide (CO) is an invisible, odorless gas that binds to hemoglobin in the blood 200 times more strongly than oxygen, preventing oxygen delivery to the body. Exposure can cause headaches, confusion, unconsciousness, and death. Sources include malfunctioning heating equipment and vehicle exhaust.
