S06TION 5 (Continued) <br /> Chronic-Exp-gouty., Product may contain respirable crystalline silica In the forms of natural quartz, <br /> Prolonged exposure to high concentrations of respirable crystalline silica In the work place may cause <br /> sillcosis and related pulmonary dies**$. In addition, a cancer health risk has been essoo(gted with <br /> respirable crystalline silica. Until an exceptable method for evaluating that risk is developed the following <br /> warning Is required In the State of California. <br /> ifil[#:•''.

Adhere to MSHA and OSHA requirements for exposure and the use of <br /> respirators in the work place (see Sections 9 and 10). <br /> Eye protection; Avoid eye contact by wearing tight fitting goggles or Wety grasses with side shields when <br /> actively working with natural aggregate material. <br /> SECTION 9 • SPECIAL PRSCAUTIONS <br /> In confined areas vsntll*tian and dust collecting epulpment can, It necaaaery, be used to control and maintain <br /> airborne dust at required levels. These precautions are especially Important for sand bleating operations that <br /> use natured fine aggregate (see Section 10), <br /> SSCTIQN 10 - AIDDITIONAL INFORMATION <br /> MSHA work place threshold limit valvae (TLV's) continue to vary with % quartz in dust. It Is currently proposed <br /> to return OSHA personal exposure limits (PEL's) to previous variable formulas that are the some as that used <br /> by MSHA, <br /> msHATLV- 10 <br /> %epics+2 <br /> Currently proposed OSHA PEi_ standard will conform to the above MSHA formula for respirable quartz and 3 <br /> timas that value for total quartz In a sample of dust material. Rsvivlons to both MSHA And OSHA standards are <br /> expected in 1993, Contact OSHA or MSHA for latest regulations regarding worker protection from quartz- <br /> bearing dust. <br /> WDS, Neturol Fina end Coarse Apyregats Pea*2 of 2 <br /> V04721'd Eeez 998 cis 11,ia 9&:eo sGGT-9i+-Auw <br />
