Discount-Equipment.com
CALIFORNIA - Proposition 65 Warning
Engine exhaust and some of its constituents and some dust created by power sanding, sawing,

to cause cancer, birth defects and other reproductive harm.
Some examples of these chemicals are:-
Lead from lead-based paints
Crystalline silica from bricks
Cement and other masonry products
Arsenic and chromium from chemically
treated lumber
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals:
ALWAYS work in a well ventilated area, and work with approved safety equipment, such as dust
masks that are specially designed to lter out microscopic particles.
