Confined Space Signs

LEM manufactures durable Confined Space signs to inform of practices and procedures to protect employees in general industry from the hazards of entry into permit-required confined spaces.

Confined spaces are such that they are large enough and configured so that an employee can bodily enter and perform assigned work; has limited or restricted means for entry or exit; and is not designed for continuous occupancy. Some examples of confined spaces are tanks, vessels, silos, storage bins, vaults, pits, sewer ducts and chambers.

OSHA rule 1910.146(c)(2) states that “If the workplace contains permit spaces, the employer shall inform exposed employees, by posting danger signs or by any other equally effective means, of the existence and location of and the danger posed by the permit spaces. A metal or plastic sign reading DANGER — PERMIT-REQUIRED CONFINED SPACE, DO NOT ENTER or using other similar language would satisfy the requirement for a sign.”
