Terms Related to Industrial Hygiene
All of these terms are based on a Discipline called Industrial Hygiene. Define the following terms. You must provide an APA citation for the sources in which you found the information
Degradation- a chemical action involving the molecular breakdown of a protective clothing material or equipment due to contact with a chemical. The molecular breakdown of the spilled or released material to render it less hazardous during control operations.
Penetration- the flow or movement of a hazardous chemical through closures, seams, porous materials, and pinholes or other imperfections in the material.
Permeation- the process by which a hazardous chemical moves through a given material on the molecular level. Permeation differs from penetration in that permeation occurs through the clothing material itself rather than through the opening in the clothing material.
Breakthrough time- the time elapsed between initial contact of the hazardous chemical with the outside surface of a barrier, such as protective clothing material, and the time at which the chemical can be detected at the inside surface of the material.
Permeation rate- the rate at which a chemical passes through a given chemical protective clothing material. Expressed as micrograms per square centimeter per minute.
Air purifying respirators (APR)-respirators or filter devices that remove particulate matter, gases, or vapors from the atmosphere. These devises range from full- face piece, duel cartridge masks with eye protection.
Powered air purifying respirators (PAPR)- air purifying respirators that use a blower to force the ambient air through air-purifying elements to a full
