Chapter 36 Hazardous Materials Response PPE Flashcards
A respirator that removes specific air contaminants by passing ambient air through one or more air purification components. (NFPA 1984)
Air-purifying respirator (APR)
Clothing (suit fabrics) specifically designed to inhibit or resist the passage of chemicals into and through the material by the process of penetration, permeation, or degradation.
Chemical-resistant materials
A chemical action involving the molecular breakdown of a protective clothing material or equipment due to contact with a chemical. (NFPA 1072)
Degradation
An excessive loss of body water. Signs and symptoms of dehydration may include increasing thirst, dry mouth, weakness or dizziness, and a darkening of the urine or a decrease in the frequency of urination.
Dehydration
Protective clothing designed to protect the wearer for short-term high temperature exposures. (NFPA 1072)
High temperature-protective clothing
Personal protective equipment that provides protection against vapors, gases, mists, and even dusts. The highest level of protection, it requires a totally encapsulating suit that includes a self-contained breathing apparatus.
Level A ensemble
Personal protective equipment that is used when the type and atmospheric concentration of substances require a high level of respiratory protection but less skin protection. The kinds of gloves and boots worn depend on the identical chemical.
Level B ensemble
Personal protective equipment that is used when the type of airborne substance is known, the concentration is measured, the criteria for using an air-purifying respirator are met, and skin and eye exposure are unlikely. A _____ _ ensemble consists of standard work clothing with the addition of chemical-protective clothing, chemically resistant gloves, and a form of respirator protection.
Level C ensemble
Personal protective equipment that is used when the atmosphere contains no known hazard, and work functions preclude splashes, immersion, or the potential for unexpected inhalation of or contact with hazardous levels of chemicals. A _____ _ ensemble is primarily a work uniform that includes coveralls and affords minimal protection.
Level D ensemble
Multiple elements of compliant protective clothing and equipment products that when worn together provide protection from some, but not all, risks of hazardous materials/WMD emergency incident operations involving liquids. (NFPA 1072)
Liquid splash-protective ensemble
The U.S. federal agency responsible for research and development on occupational safety and health issues.
National Institute for Occupational Safety and Health (NIOSH)
The movement of a material through a suit’s closures, such as zippers, buttonholes, seams, flaps, or other design features of chemical-protective clothing, and through punctures, cuts, and tears. (NFPA 1072)
Penetration
An air-purifying respirator that uses a powered blower to force the ambient air through one or more air-purifying components to the respiratory inlet covering. (NFPA 1984)
Powered air-purifying respirator (PAPR)
A respirator worn by the user that supplies a respirable atmosphere, that is either carried in or generated by the apparatus, and that is independent of the ambient environment. (NFPA 350)
Self-contained breathing apparatus (SCBA)
An atmosphere-supplying respirator for which the source of the breathing air is not designed to be carried by the user. Also known as an “airline respirator.” (NFPA 1989)
Supplied-air respirator (SAR)
Multiple elements of compliant protective clothing and equipment that when worn together provide protection from some, but not all, risks of vapor, liquid-splash, and particulate environments during hazardous materials/WMD incident operations. (NFPA 1072)
Vapor-protective ensemble

the
A. incident commander.
B. safety officer.
C. hazardous material technician.
D. crew captain.

B. degradation.
C. permeation.
D. vaporization.
A. penetration
The physical destruction of clothing due to chemical exposure is called
A. penetration.
B. degradation.
C. permeation.
D. vaporization.
B. degradation
Chemical resistance, flexibility, abrasion, temperature resistance, shelf life, and sizing criteria are
requirements that need to be considered when selecting
A. entry tools.
B. respirators.
C. testing equipment.
D. chemical-protective materials.
D. chemical-protective materials.
