HASP Central Plume — Mid Plume <br />531 S. Church Street, Lodi, CA <br />Selection Criteria <br />The EPA has classified personal protective equipment (PPE) ensembles into four categories for different <br />levels of hazards. They are as follows: <br />Level A <br />This type of protection should be worn when the highest level of respiratory, skin, <br />eye and mucus membrane protection is needed. <br />Level B <br />Level B protection should be selected when the highest level of respiratory <br />protection is needed, but a lesser level of skin and eye protection. <br />Level C <br />This level protection should be selected when the actual or potential airborne <br />substance(s) is known, the concentration(s) is measured, the criteria for using <br />air- purifying respirators are met, and skin and eye exposure is unlikely. Periodic <br />air monitoring is necessary. <br />Level D <br />Level D is primarily work clothing. <br />The PPE selection criteria for unexpected toxic hazards that may be encountered are based on <br />two major parameters: <br />Type(s) and measured concentration(s) of the chemical substance(s) in the atmosphere, <br />with its (their) associated toxicity. <br />Potential for exposure to high air concentrations of volatile substance, splashes of liquids, <br />or other types of direct contact with material due to work functions being performed. <br />PPE for activities where the identity of contaminants is available requires consideration of the <br />following. <br />Identity of either known or suspected contaminant <br />Actual or potential airborne concentration <br />Skin toxicity data <br />Potential for skin or eye contact <br />Contaminated Area PPE Requirements <br />Anticipated exposures by all occupationally relevant routes is not expected to be significant. <br />Therefore, the following (EPA level D) personal protective equipment shall be worn in <br />contaminated areas: <br />6 <br />water <br />11
