Manhole Cover Signs, Guards & Accessories

Yes, OSHA 29 CFR 1910.146 requires that permit-required confined spaces such as manholes be identified and marked to warn employees of the hazard and prevent unauthorized entry, and our danger confined space manhole cover sign satisfies the hazard identification posting requirement for workers, contractors, and the public near any marked manhole location.

Yes, our manhole cover signs collection includes both rigid plastic for post or wall mounting near the manhole and adhesive vinyl labels that apply directly to the cover surface itself, with adhesive labels being the most common choice because they mark the hazard exactly at the point of risk on the cover where anyone approaching will see the confined space warning before stepping close enough to be in danger.

Yes, our customizable templates from our manhole cover signs collection let you add permit-required confined space language, atmospheric testing requirements, authorized entry personnel, or emergency contact numbers, and our permit required confined space ANSI danger sign is one of our most commonly paired options for utilities and municipalities with specific confined space entry programs.

For outdoor manhole covers exposed to weather and foot traffic we recommend durable adhesive polyester labels from our manhole cover signs collection that bond firmly to metal and concrete cover surfaces and withstand rain, temperature changes, UV exposure, and the weight of foot and vehicle traffic, with the lid cover manhole guard also popular for high-visibility marking at road and sidewalk locations.
