The CDN Danger Open Hole safety sign (Ref: ECD418) is a critical hazard communication tool designed to prevent falls and serious workplace injuries. Engineered to meet CSA Z321 standards and OSHA safety requirements, this sign ensures immediate identification of unprotected openings in industrial floors, construction sites, and maintenance areas.
Ensuring workplace safety requires more than just a warning; it requires high-visibility signage that stands up to harsh environments. Our signs are built for durability and regulatory compliance.
This sign adheres to the CSA Z321 standard for color coding and symbols, ensuring your facility remains compliant with CNESST and Canadian safety inspections. The clear "Danger" header alerts workers to high-risk hazards that require immediate attention.
Select the best material for your specific working conditions:
Adhesive Vinyl (4 mil): Best for smooth surfaces, indoor use, and quick application.
Rigid Plastic (60 mil): Impact-resistant and versatile for general industrial use.
Heavy-Duty Aluminum (40 mil): The premium choice for outdoor environments, offering maximum resistance to corrosion, UV rays, and extreme temperatures.

Expert Insight: "To meet safety standards, signs should be mounted at eye level (approx. 5 feet or 1.5m from the floor) in a well-lit area. For construction sites where dust and debris are common, we strongly recommend the aluminum version with a protective laminate. This allows for easy cleaning of concrete dust or grease without damaging the safety graphics, extending the sign's lifespan significantly."
Installation depends on the chosen material. Vinyl models adhere easily to clean, smooth surfaces, while plastic or aluminum versions can be screwed or suspended. L-shaped formats are perfect for hallways, and V-shaped formats offer 180-degree visibility in open zones. It is recommended to place the sign at eye level, directly near the opening to be marked.
Use the CDN danger open hole sign in all areas where an unprotected opening may pose a danger to workers or visitors. Make sure it is clearly visible and not obstructed. Complement your signage with other CDN signs to cover all existing risks. Coherent and well-positioned signage helps reduce accidents and strengthens workplace safety.
