DANGER Confined Space CO2 Hazard Sign – Permit Required – 8x12 Aluminum

Confined spaces that are subject to CO2 enrichment or have the potential for CO2 accumulation present an extremely high risk of oxygen deficiency, leading to severe injury or fatality. This DANGER sign is engineered to clearly mark such hazardous areas, enforcing strict permit-required entry procedures. This is a critical measure for safeguarding personnel from asphyxiation and other atmospheric hazards inherent to these restricted environments.

The explicit 'Permit Required' directive on this sign is vital for compliance with occupational safety regulations, ensuring that all necessary precautions—such as atmospheric testing, ventilation, and rescue plans—are in place before any personnel access. It serves as an indispensable visual reminder to maintain rigorous control over entry into tanks, pits, vaults, or other enclosed spaces where CO2 concentrations could rapidly become lethal.

Common placements:

• Entrances to fermentation tanks in breweries or distilleries.
• Access hatches for underground CO2 distribution vaults.
• Doors to walk-in humidors or controlled atmosphere storage units.
•  Access panels for large sealed environmental chambers.
• Maintenance points for CO2 scrubbing or recovery systems.

Construction features:

• Rust-resistant aluminum construction.
• UV-resistant graphics for fade prevention.
• Pre-drilled holes for easy mounting.
• Rounded corners for safe handling.

Operational note: Ensure all personnel involved in confined space entry are trained in gas monitoring, rescue procedures, and the specific hazards associated with CO2 accumulation.

• Control access to confined spaces with CO2 enrichment hazards, unequivocally stating the mandatory requirement for a permit before any entry is attempted.
• Support safer confined space operations by providing a visible warning of oxygen displacement risks and enforcing critical permit-to-enter protocols.
• Built for harsh conditions: Made from rust-resistant aluminum with UV-resistant printing for long-term outdoor and indoor durability in heat, rain, and humidity.
• Fast, clean installation: Pre-drilled mounting holes and rounded corners support quick mounting on gates, fences, doors, walls, and equipment areas.
• Made by CGAP Safety: CGAP Safety is an American safety manufacturer focused on durable, professional-grade facility and jobsite signage.
