Observe and follow safety instructions such as NO SMOKING, HIGH VOLTAGE and
DANGER in your working area.
Accidents can occur that result in serious injury to you or others due to clothing and
other articles becoming entangled or in contact with revolving parts, levers and
electrical equipment.
a.
Do not wear neckties, scarves or loose-fitting clothing.
b.

Use safety protective equipment. An OSHA-NIOSH approved respirator must be worn
at all times while blasting, changing filter cartridges, emptying dust collection drawers,
and when handling media that contains free levels of silica and toxic material that are in
excess of those allowed by applicable OSHA, USEPA, ACGIH or NIOSH regulations
and recommendations. Wear clean, approved eye or face protection. Keep your
protective equipment in good condition. Wear sturdy safety-toe shoes with slip-proof
soles.
