,Which type of respiratory protection does not require fit testing and provides loose-
fitting, lightweight protection to the user? - CORRECT ANSWER Supplied air-
hood.
Chemicals absorbed into clothing: - CORRECT ANSWER can cause repeated
exposure or later reaction with another chemical.
What PPE protects a responder while working in a total flame environment for a short
period of time? - CORRECT ANSWER Fire-entry suit.
Which type of protective clothing should responders use when handling cryogenic
materials? - CORRECT ANSWER Low-temperature protective clothing
Which class of ensemble provides the wearer the highest level of skin and respiratory
protection from vapors and liquid-spray? - CORRECT ANSWER Class 1.
Ideally, which statement regarding doffing procedures for a responder exiting the hot
zone is accurate? - CORRECT ANSWER Assisting personnel doff PPE and
equipment from exiting responders.

hazardous, corrosive, and/or toxic vapors or gasses
When selecting PPE, why is it important to consider the duration of exposure? -

material's chemical resistance.
, Permeation occurs when: - CORRECT ANSWER a chemical passes through a
fabric on a molecular level.
The rate at which a compound permeates chemical protective clothing (CPC) depends
on: - CORRECT ANSWER the concentration of the chemical on the surface of the
CPC.

CORRECT ANSWER Decreased ability to communicate
What is a limiting factor of using self-contained breathing apparatus (SCBA) at a
hazardous materials incident? - CORRECT ANSWER SCBA has a finite air-
supply, limiting work duration.
Why should supplied-air respirators (SARs) NOT be used in fire fighting operations? -
CORRECT ANSWER Heat, fire, or debris can damage the SAR airline
What is an advantage of using a supplied-air respirator (SAR) compared to using self-
contained breathing apparatus (SCBA) in a hazardous environment? - CORRECT
