Respirable crystalline silica may cause cancer - silica danger sign
Osha silica standards require employers to mark-off regulated areas of the workplace where exposures to respirable crystalline silica are, or can reasonably be expected to be, above the pel. Employers must post a sign at each entrance to regulated areas informing employees of the hazards associated with the area as well as the need for respiratory protection. Our plastic signs are constructed using an economical, durable, . 040 polystyrene plastic - they are moisture and weather resistant. Ideal for both indoor and outdoor use. Signs come standard with pre-drilled mounting holes and radius corners.
