Workers who service or maintain industrial machines are at significant risk if energy sources are not properly controlled. 

Hazardous energy can come from multiple sources, including electrical, mechanical, hydraulic, pneumatic, chemical, and thermal energy. 

If a machine unexpectedly starts while a worker is inside or near a hazardous area, it can result in amputations, electrocution, burns, crushing injuries, or even death.

In Canada, energy-related workplace injuries remain a serious concern. Many injuries result from improper lockout/tagout procedures, emphasizing the need for strict adherence to LOTO protocols.

OSHA and LOTO Regulations

In the U.S., the Occupational Safety and Health Administration (OSHA) has established a comprehensive standard for controlling hazardous energy, known as 29 CFR 1910.147.

This regulation outlines the minimum requirements for protecting employees from hazardous energy in general industry settings. 

While Canada follows its own occupational health and safety standards, many principles align with OSHA’s guidelines to ensure worker protection.

Key provisions of OSHA’s LOTO standard (29 CFR 1910.147) include:

• Developing and enforcing a written energy control program.
• Training employees on proper lockout/tagout procedures.
• Identifying and labeling all hazardous energy sources.
• Using appropriate lockout devices and tags to secure machinery.
• Conducting periodic inspections to ensure compliance.

LOTO in the Canadian Workplace

In Canada, each province has its own workplace safety regulations, but all emphasize the importance of lockout procedures for hazardous energy control. 

Organizations like the Canadian Centre for Occupational Health and Safety (CCOHS) and provincial regulatory bodies set LOTO guidelines to protect workers.

Employers must implement energy control programs that align with these regulations to maintain compliance and reduce workplace risks.

By following OSHA’s standards and Canadian occupational safety regulations, companies can create safer work environments and prevent life-threatening incidents.
