What type of hazard does a lockout/tagout (LOTO) procedure address?

Lockout/tagout (LOTO) procedures are specifically designed to address hazardous energy control. The purpose of LOTO procedures is to ensure that machinery and equipment are properly shut off and not able to be started up again before maintenance or repair work is completed. This is crucial in preventing the unintended release of energy – whether it's electrical, mechanical, hydraulic, pneumatic, thermal, or other forms of energy – that could cause harm to workers.

Implementing LOTO procedures involves identifying and isolating hazardous energy sources, locking or tagging the controls to prevent accidental re-energization, and ensuring that only authorized personnel may remove the locks or tags. This method not only protects workers from potential injuries caused by unexpected machine operation but also reinforces the importance of following safe operating procedures.

Other types of hazards listed in the options, such as chemical, physical, or biological hazards, do not specifically relate to the overarching goal of LOTO procedures. While these hazards may be present in the workplace, LOTO primarily focuses on controlling the risks associated with hazardous energy during maintenance activities.
