Degradation - Correct Answer-Loss or change in chemical resistance due to exposure or ambient conditions Penetration - Correct Answer-Movement through zippers, seams, or imperfections in suit Factors affecting the rate of permeation of a suit. - Correct Answer-Concentration of the hazardous substance. Suit material type and thickness. Temperature. Level A suits (9.7.2.1) - Correct Answer-Highest level of respiratory, skin, eye and mucous membrane protection is required Level B Suits (9.7.2.2) - Correct Answer-Highest level of respiratory, but lesser level of skin and eye protection. (minimum level of protective suits in IDLH conditions or when haz material is unknown). When is using a level C suit appropriate? - Correct Answer-When type of airborne substance is known, its concentration has been measured and criteria for using APRs have been met. Essentially, what is a Level D suit (9.7.2.4) practically speaking? - Correct Answer-A work uniform. When should a decon plan be put in place in the site response process? - Correct Answer-Before any personnel or equipment enter potential hazardous areas What can improper decon procedures can lead to - Correct Answer-Chemical reactions due to incompatibility. Release of toxic or flammable vapors. Degradation of PPE. Some decon scenarios require personnel to wear PPE at the same level as those entering Exclusion Zone (EZ) exceptions to this rule allow for??? - Correct Answer- decon personnel to wear level just below those entering EZ.
