Communication is a vital component to any lockout-tagout (LOTO) program. OSHA essentially mandates this with a list of recommended procedures to be followed, but not all LOTO safety programs are the same. The most effective companies use dedicated signage and identification on specifically designated lockout devices and padlocks to keep workers informed and provide them with a safer environment.
Visual communication that accurately and precisely informs your personnel of potentially dangerous conditions should be your goal. This can be accomplished by using signs and tags that are tested to withstand extreme conditions and provide clear, consistent messages to describe situations so workers can do their job and maintain equipment.
