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.
