What signs are required for silica hazard areas?

Areas with respirator crystalline silica must be marked to prevent unauthorized entry.  The requirement for signs are different for construction and general industry.

Silica Signs for General Industry

1910.1053(j)(2) requires that silica regulated areas be marked with a sign that reads:

DANGER
RESPIRABLE CRYSTALLINE SILICA
MAY CAUSE CANCER
CAUSES DAMAGE TO LUNGS
WEAR RESPIRATORY PROTECTION IN
THIS AREA
AUTHORIZED PERSONNEL ONLY

You can find the respirable crystalline silica danger sign here.

 Silica Signs for Construction

 Silica construction regulations have no specific requirements for signs.  1926.1153(g)(1)(iv) does require the employer to include the method for restricting access to silica hazard areas as part of the exposure control plan.  This would include signs or markings of some sort, but the method of communication is up to the employer.
