This OSHA Safety Lockout/Tagout (LOTO) Padlock features a heavy-duty metallic shackle and is equipped with a Master Key (MK) System, meaning each padlock has its own unique key, but a single Master Key can open ALL padlocks in the set. This is ideal for supervisors, safety officers, or managers who need override access during emergency situations or audits — without compromising individual worker lock ownership.
Designed and built to comply with OSHA Standard CFR 29 Part 1910.147 for the Control of Hazardous Energy (Lockout/Tagout).
