Proper lockout tagout practices safeguard workers from the release of hazardous energy. Workers must be trained in the function of the energy control program and have the skills required for safe application usage and removal of the energy control devices.
the placement of both a lock and tag by an authorized worker on an energy isolating device in accordance with AFOSH 91-502 Chapter 21 to ensure that the energy-isolating device and the equipment being controlled cannot be operated until the lock is remove
Isolation and lock-off procedures involve shutting down equipment, disconnecting energy sources (such as electrical, hydraulic, or pneumatic), and securing them to prevent accidental re-energization. A Permit to Work (PTW) system ensures that all hazards are assessed, and necessary safety measures are implemented before maintenance begins. This includes clearly labeling isolation points, using lockout/tagout devices, and obtaining authorization from a responsible supervisor. Documentation of the procedures and verification that the equipment is de-energized are critical steps to ensure worker safety during maintenance activities.
that is the key code for that particular type of lock or cylinder. So if you see that code on the cylinder lock that is the key for it.
A lock washer overlaps itself when it is new so that when you tighten the nut down the pressure causes it to flatten out and in turn put pressure against the nut and whatever it is against. The pressure plus the gap in the washer helps prevent the nut from turning.

Lockout/Tagout (LOTO) is a safety procedure used to ensure that machinery is properly shut off and not able to be started up again before maintenance or servicing work is completed. It involves placing a lock (lockout) on the energy-isolating devices and a tag (tagout) to warn others that the machinery should not be operated. This practice is critical for preventing accidental machine startup, protecting workers from injuries, and ensuring a safe working environment. Compliance with LOTO regulations is essential in industries where machinery poses potential hazards.

The isolation and lock-off procedure, also known as the permit to work procedure, involves several key steps to ensure safety during maintenance. First, all energy sources to the equipment must be identified and isolated using appropriate lockout/tagout (LOTO) devices to prevent accidental re-energization. Next, a work permit is issued, detailing the scope of work, potential hazards, and safety measures required. Finally, the area is secured, and only authorized personnel are allowed to access the equipment until maintenance is completed and the permit is closed.

locks and tags must clearly indicate that the operation of the energy- isolating device is prohibited
Only authorized personnel who have been trained in lockout/tagout procedures can remove a lockout/tagout from a machine. This typically includes maintenance workers or operators who have the authority and knowledge to ensure that the machine is safe to operate. The removal should only occur after confirming that all personnel are clear from the machine and that it is safe to restore power. Additionally, the person who applied the lockout/tagout should ideally be the one to remove it, unless they are unavailable, in which case specific procedures should be followed.
