Work out lockout tagout point count instantly with clear inputs, formula shown and shareable results.
Lockout requires every energy source to be isolated at every point and every worker to have personal control over the isolation. Locking each point individually multiplies locks by workers and becomes impractical quickly. A group lock box holds the keys to the point locks and each worker fits a personal lock to the box, so the count becomes points plus workers.
Individual method
Locks = isolation points x workers
Group lock box
Locks = isolation points + one personal lock per worker
Preliminary estimate only. Energy isolation procedures must be developed for each machine and comply with the applicable lockout regulations.
Locks = isolation points x workers. Lockout requires every energy source to be isolated at every point and every worker to have personal control over the isolation.
So that no one else can restore energy while that worker is exposed. A shared or supervisor-held lock removes the individual protection that is the entire point of the system.
This calculator takes 4 inputs: Energy sources to isolate, Isolation points per source, Workers requiring personal locks, Group lockout method. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
