Safety design of lockout padlocks - The front of the lockout device features a waterproof, corrosion-resistant high-quality label to remind personnel of hazards and help reduce safety incidents. The key retention function is designed so that the key cannot be removed unless the lockout is successfully applied. Durable construction - Made from impact-resistant stainless steel for exceptional durability and long-lasting performance. Warning and hazard communication - Use these labels to clearly mark scaffold conditions and warn others about potential hazards to protect your workers. OSHA compliant LOTO locks - Lockout/tagout locks meet OSHA requirements and undergo rigorous testing. The brass key-retaining cylinder prevents key removal when the lock is in the unlocked position, adding security and helping to limit key loss. Application - Designed exclusively for locking and tagging applications. Commonly used on power source keys, air source keys, pipeline valves, and mechanically fixed moving parts. Use scenarios - Electrical maintenance: apply to power source keys or electrical panel locks to prevent energization during servicing. - Pneumatic and hydraulic systems: secure air source controls to ensure maintenance can proceed safely. - Pipeline and mechanical equipment: lock pipeline valves or moving parts to prevent unintended operation during repair or adjustment. - Scaffold and elevated work: clearly mark scaffold status and hazards to protect workers on elevated platforms.
