What should be done to ensure power to the machine is isolated during maintenance?

To ensure power to the machine is isolated during maintenance, employing a physical lockout method is essential. The lockout method involves using lockout devices that physically prevent the machine from being energized. This is a fundamental component of the Lockout/Tagout (LOTO) standard, which is designed to protect workers from unexpected machine startups or releases of hazardous energy while they are servicing or maintaining equipment.

Physical lockout devices, such as locks and tags, create a clear and secure indication that work is being performed on a specific piece of equipment. This approach not only prevents the accidental re-energization of the machine but also provides a means for personnel to clearly see that the machine is not safe to operate. Such measures are critical in preventing workplace accidents and ensuring the safety of maintenance personnel.

While visual warning signs, verbal communication, and other methods may play roles in raising awareness about ongoing maintenance, they do not provide the same level of security as a physical lockout. Visual signs can be ignored, and verbal communication may not be sufficient if other personnel are present or if distractions occur. Increasing the machine's speed is contrary to safe maintenance practices and poses significant risks. Thus, employing a physical lockout method is the most reliable means of safeguarding workers during maintenance
