Confined Space Manhole Covers keep your confined spaces and workers safe. They are placed directly under the manhole cover so they are visible when the manhole cover is removed from the confined space entry to prevent unauthorized entry and remind workers to follow proper confined space procedures. The label that is affixed to the manhole cover is made of indoor/outdoor grade over-laminated polyester.
This label reads:CAUTION. Confined Space. Do not enter without obtaining permit.
Available in two sizes: 21"-30" diameter manhole or 30.5"-42" diameter manholes. See items #08510-08516 for additional legend choices. Custom legends are also available.
