Personal Protective Equipment
Respiratory – If respirators are selected, use and maintain in accordance with ANSI
Standard (Z88.2) for particulate respirators. Select respirators based on the level of
exposure to crystalline silica as measured by dust sampling. Use respirators that offer
protection to the highest concentrations of crystalline silica if the actual concentrations
are unknown. Put in place a respiratory protection and monitoring program that
complies with MSHA or OSHA (e.g. 29CFR1910.134) standards, which include provisions
for a user training program, respirator repair and cleaning, respirator fit-testing and
other requirements. Comply with all other applicable federal and state laws.
Eye – When cutting material, dust resistant safety goggles / glasses should be worn and
used in compliance with ANSI Standard Z87.1 and applicable OSHA (e.g. 29CFR1910.133)
standards.
Skin – Loose comfortable clothing should be worn. Direct skin contact with dust and
debris should be avoided by wearing long sleeved shirts and long trousers, a cap or hat,
and gloves. Work clothes should be washed regularly.

Section 10. Stability and Reactivity
Stability:
Crystalline silica and limestone are stable under ordinary conditions
Conditions to Avoid:
Excessive dust generation during storage and handling
Materials to Avoid:
Hydrofluoric acid will dissolve silica and can generate silicon tetrafluoride,
a corrosive gas. Contact with strong oxidizing agents such as fluorine,
boron trifluoride, chlorine trifluoride, manganese trifluoride or oxygen
difluoride may cause fires and /or explosions. Furthermore, limestone is
incompatible with acids and ammonium salts.
Section 11. Toxicological Information
Routes of exposure:
Fiber-cement is not toxic in its intact form. The following applies to dust
that may be generated during cutting, rebating, drilling, routing, sawing,
crushing or otherwise abrading fiber cement.
