1.1 This practice is designed to protect the health and safety of workers exposed to the specific synthetic amorphous silica dusts, or mixtures thereof.
1.2 Actions recommended in subsequent sections of this practice apply where the time-weighted average (TWA) occupational exposure to the silicas is in excess of the permissible exposure limit (PEL) of 5 mg/m of respirable dust (see 5.1.1), as determined by monitoring in 5.7.
1.3 Nothing in this practice shall be interpreted as requiring any action that violates any statute or requirement of any federal, state, or other regulatory agency.
1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. It is the responsibility of the user to consult all material safety data sheets and labels pertaining to any hazardous materials used in this standard.
