- Confined Space Signage

Confined Space Signage.
Confined spaces pose serious risks—from toxic atmospheres to entrapment and low oxygen levels. Identimark’s Confined Space Signage is designed to clearly mark these hazards in line with Australian and New Zealand safety regulations, including AS/NZS 1319. Built using our industry-leading U3 material, these signs are made to withstand harsh environments for decades without fading or failure. Trusted by infrastructure, energy, water, and manufacturing sectors, our signage ensures that workers and responders are aware, informed, and protected before entry.
