Perhaps you are wondering what kind of lock
should be usedkey or combination? What person
should have a lock? Who should be in possession of
the keys or combinations? How should the lock be
identified? The answers to these questions may vary
from one activity to another, but some guidelines are as
1. Key-operated padlocks are more commonly
used than combination locks. Supervisors can control
keys easier than combinations.
2. Locks should be issued to every person who
works on closed-down equipment. No key (or
combination) should fit more than one lock.
3. Only one key should be issued to a person
authorized to use the lock. At some activities, the
supervisor may be permitted to maintain a duplicate set
of keys for locks under his/her control, or a master key.
Some activities, however, may have only one lock-one
key. In an emergency, bolt cutters may be used to
remove a lock. As a word of caution: KEYS AND
LOCKS SHOULD NEVER BE LOANED.
4. Locks should identify the user by name, rate,
and shop. This information can be stamped into the lock
case, stenciled on, or carried on a metal tag fixed to the
shackle of the lock. In addition, locks may be color
coded to identify the skill or rating of the lock folder,
such as UT, CE, or CM. The colors could also follow the
hard hat color code.
