Moreover, Article 186 of the RSST provides an
alternative to lockout under specific circumstances:
Article 186. Adjustment, repair, unjamming, maintenance
and apprenticeship: When a worker must access a machine’s danger zone for adjustment, unjamming, maintenance, apprenticeship or repair purposes, including for detecting abnormal operations, and to do so, he must move or remove a protector (guard), or neutralize a protective device, the machine shall only be restarted by means of a manual control or in compliance with a safety procedure specifically provided for allowing such access.
