® testing will be conducted with isoamyl acetate for organic vapor cartridges and <br /> ® irritant smoke (stannic chloride) for particulate filter cartridges prior to respirator <br /> use on site. The above notwithstanding, these provisions should not be <br /> ® intended to preclude otherwise unauthorized personnel from emergency use of <br /> respirators or voluntary upgrading. Documentation for compliance with these <br /> ® provisions should be maintained. <br /> ® 2. Persons with interfering facial hair shall not be permitted in areas where <br /> ® respiratory protection equipment is required; i.e., beards are prohibited_ <br /> 3. Permanent damage to the eyes (cornea) from acid gases and particulates may <br /> ® result if contact lenses are worn. Therefore, wearing contact lenses on site <br /> shall be prohibited. Those persons shall have prescription' spectacle inserts <br /> ® installed in their respiratory protective equipment. <br /> 4. All NIOSH procedures and guidelines for respirator selection and use should be <br /> adhered to. Only equipment certified by NIOSH in its most recent certified <br /> equipment list will be used. APRs with chemical cartridges can only be used <br /> ® for acid gas/organic solvent vapors under the following conditions: <br /> ® ♦ If the oxygen concentration is satisfactory. <br /> ® ♦ If the chemical contaminants have been identified. <br /> ® ♦ The concentrations are monitored_ <br /> ® ♦ The chemical filter cartridges are effective in removing the contaminants. <br /> ♦ The cartridges are approved for such use (by NIOSH). <br /> ® ♦ The contaminants have good warning properties. <br /> If all of the above conditions cannot be satisfied, then Level B protection using <br /> ® pressure-demand SCBAs or supplied air is required. APRs with chemical <br /> ® cartridges/canisters will not be used for protection in environments containing <br /> ® constituents which have poor warning properties, and which are at or above, <br /> ® or can reasonably be expected to be near, at, and/or above the limitation of the <br /> ® protection factor (PF) for the respirator. The maximum working environment <br /> shall be determined by multiplying the PF for the type of respirator by the TLV <br /> ® for the chemical substance under consideration, (MUC = PF X TLV)_ A list of <br /> PFs is shown in TABLE 2. <br /> ® 1:23 <br />
