Individually keyed lock and information tag
Lockout: Individually keyed lock and information tag
The ROHS define the “individually keyed” concept in the section 188.1 as a special layout of the components of a lock making it possible to open it with a single key.
The safety lock is the centrepiece of any lockout tag out procedure used to keep, mechanically, the energy isolating devise or lockout device in a safe position.
It is right that the definition of “individually keyed” and “safety lock ” seems to be obvious, however, is becomes more complicated to assimilate in a real work environment context.
With several types of locks and different uses, locks management should be considered as an essential task to reach an optimal efficiency of a lockout program.
- Used by a worker to ensure personal lockout protection such that each lock when applied is operable only by a key in the worker’s possession
- The name of the person must be clearly indicated on the individually keyed lock
- If the employer provides locks with no name indication, then he must keep a record containing lock information
Information on tag
- The tag, eventually, attached to the personal lock.
- The reason for the lockout.
- The name of the person who applied the lockout.
- The date that the lockout was applied.
- May contain the name of the equipment in lockout.
- Indications like “Danger Do Not Start” or “Danger Do Not Operate” are usually written on the tag.
Group or multiple lockout locks
- It’s a set of “keyed alike” locks (set of locks with a single key) used in group lockout situations, so workers can put their locks on the box containing the key (lockout box) instead of locking each energy-isolating device separately.
- Number of locks in the set should be indicated on the locks or the attached tags.
Control, transition or departmental lock
- This type of lock replaces a personal lock when the worker must leave the worksite at the end of the shift or to lockout a piece of equipment for one or more days, it is also used by a supervisor to keep the equipment locked out to control and supervise the unlocking operation.
- In all cases, the reason for using this lock must be indicated on the attached tag
- Used when workers need more locks than they have as personal, or borrowed to external contractors.
- Borrowing locks must have a distinct color.
- It is also mandatory to keep a record containing name of the person, time and date at which the lock is given and returned and the reason of the borrowing.
