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
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.

A Welding Procedure Specification (WPS) is a document that provides variables and conditions of a welding procedure that is produced for a very specific application. To write one properly, experimentation and calculations must be done to find the correct parameters for the procedure. To generalize, a WPS must include all known parameters of the process; including process type, current, current type, voltage, shielding gas type, shielding gas flow rate, base metal, electrode type and size, filler metal type and size, joint design, and travel speed. There may be more variables than listed, depending on the application. One must also remember that on a WPS, ranges for variables are used that are adjustable by the welder or welding operator. Ex. Current (Amperage) 150-170 A instead of just saying 155 A. To find these ranges is where calculations are necessary.

locks and tags must clearly indicate that the operation of the energy- isolating device is prohibited
locks and tags must clearly indicate that the operation of the energy-isolating device is prohibited
locks and tags must clearly indicate that the operation of the energy-isolating device is prohibited
D. All of the choices are correct.
Some vehicles will not let you lock the door when it is opened. This is a safety procedure ensuring you don't lock your keys in the car, get locked out.
Notify.
an action performed by a second authorized worker that requires checking the position of an energy-isolating device for the application or removal of a lockout/tagout.
