ANSI Warning Automated Machinery Stay Clear Lockout Tagout Before Servicing Sign Stickers

This sign communicates two critical safety messages: the machinery is automated and workers should stay clear during operation; and full lockout/tagout procedures must be completed before any servicing or maintenance work begins. The combination makes this sign especially valuable at control panels and service access points where both hazards are simultaneously present.

OSHA 29 CFR 1910.147 (Control of Hazardous Energy / Lockout Tagout) requires employers to develop and implement an energy control program for all equipment where unexpected energization could cause injury. On-equipment lockout/tagout signs are a recognized administrative control reinforcing the written program at the point of service. ANSI Z244.1 (Control of Hazardous Energy) provides additional industry guidance supporting this sign's message.

Post at all service access points on automated machinery including control panel covers, maintenance doors, electrical enclosures, and any point where a worker would open or access the machine for servicing. This sign is most effective when posted directly at the service access point so the lockout/tagout reminder is seen immediately before access is opened.

Lockout involves physically locking an energy isolation device in the safe position using a lock, preventing re-energization. Tagout involves attaching a warning tag to the isolation device. OSHA 29 CFR 1910.147 requires lockout wherever possible, with tagout only as an alternative where lockout is not feasible. Your facility's written energy control program should specify which method applies to each piece of automated equipment.

Yes. The Lockout/Tagout message applies to all types of hazardous energy electrical, mechanical, hydraulic, pneumatic, thermal, and chemical as covered under OSHA 29 CFR 1910.147. The Automated Machinery Stay Clear message applies to all automated equipment regardless of energy type.
