• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed
to filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction
activities. Wear protective clothing and wash exposed
areas with soap and water. Allowing dust to get into your
mouth, eyes, or lay on the skin may promote absorption of
harmful chemicals.

which may cause serious and permanent respiratory or other
injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face
and body. Always operate tool in well-ventilated area and provide
for proper dust removal. Use dust collection system wherever
possible.
