188.12. Where a lock is forgotten or a key is lost, the employer who has authority over the establishment may, with the agreement of the person who carried out lockout, authorize the lock to be removed after ensuring that it does not involve any danger for the health, safety and physical well-being of that person.
Where the agreement of the person who carried out lockout is not obtained, the employer who has authority over the establishment must, before authorizing the lock to be removed, inspect the danger zone of the machine accompanied by a representative of the certified association of which the person is a member, if he or she is available on the work site or, failing that, by a worker present on the work site designated by the employer.
Every instance of a lock being removed must be entered in a written document kept by the employer for at least one year following the day on which the applicable energy control method is altered.
