Confined spaces have a way of looking completely harmless from the outside. A manhole, a storage tank, a utility vault, none of them look particularly threatening until you understand what can be happening inside them. Oxygen deficiency, toxic gas accumulation, and engulfment hazards are all real and all invisible, and by the time someone inside realises something is wrong, it can already be too late to act. Confined Space Signs exist to make that invisible danger impossible to ignore before anyone gets to the entry point, marking every confined space clearly so that no worker approaches without knowing exactly what they are dealing with.

Right at the entry point of every space that qualifies as a confined space in your facility. Manholes, utility vaults, storage tanks, silos, tunnels, boilers, pipelines, and crawl spaces all need clearly posted Confined Space Signs that are visible before someone reaches the entry point. In industrial, construction, municipal, and utility environments where confined space entry is a regular part of the operation, these signs should be permanently in place and never taken down between entries.

Yes. Confined Space Signs fall under both OSHA 29 CFR 1910.145 for accident prevention signs and tags and OSHA 29 CFR 1910.146 for permit-required confined spaces, which lays out specific, detailed requirements for identifying, marking, and managing every confined space entry. Posting proper Confined Space Signs is not just responsible practice. It is a regulatory obligation, and failing to have them in place can result in significant OSHA penalties and consequences that are far more serious than a fine.

No. Confined Space Signs mark where the hazard is. They do not control what the hazard does to someone who enters unprepared. A full written confined space program covering atmospheric testing, ventilation procedures, permit-to-enter requirements, rescue planning, and comprehensive training for every worker who enters or works near a confined space is non-negotiable.

Yes. Confined Space Signs are made from durable waterproof vinyl built to hold up in the tough outdoor and industrial environments where confined spaces are most commonly found. They stay clearly legible and firmly in place without peeling, fading, or becoming difficult to read over time, which matters enormously in environments where these signs need to be doing their job reliably every single day of the year.

Yes. Several Confined Space Signs in this collection are available in both English and Spanish. In industrial, construction, and utility environments where multilingual teams are the norm and the hazards of confined space entry are genuinely life-threatening, having the warning clearly communicated in both languages is essential.

Every order comes with 5 Confined Space Signs per pack, made in the USA. For large facilities, operations with multiple confined space entry points, or multi-site setups, reach out at orders@stickerjet.com and the team will take care of the rest.

The signs come in different sizes. Some common sizes for hazard signs are 3.5" x 5", 5" x 7", 7" x 10", 10" x 14". These sizes ensure that the signs are visible and easy to read. These signs need to be big enough to grab people's attention and small enough to fit in the space available.
