Lockout Tagout (LOTO)

Purpose

This Lockout Tagout (LOTO) training class covers specifics regarding the OSHA Standard (Control of Hazardous Energy) and information to assist the attendee in establishing and implementing a Lockout/Tagout program for their work place. The course objectives will also provide the attendees with information and an understanding of specific elements of a Lockout Tagout program.

OSHA Definition of “Lockout/tagout” refers to specific practices and procedures to safeguard employees from the unexpected energization or startup of machinery and equipment, or the release of hazardous energy during service or maintenance activities.1 This requires, in part, that a designated inpidual turns off and disconnects the machinery or equipment from its energy source(s) before performing service or maintenance and that the authorized employee(s) either lock or tag the energy-isolating device(s) to prevent the release of hazardous energy and take steps to verify that the energy has been isolated effectively. If the potential exists for the release of hazardous stored energy or for the reaccumulation of stored energy to a hazardous level, the employer must ensure that the employee(s) take steps to prevent injury that may result from the release of the stored energy.

Lockout devices hold energy-isolation devices in a safe or”off” position. They provide protection by preventing machines or equipment from becoming energized because they are positive restraints that no one can remove without a key or other unlocking mechanism, or through extraordinary means, such as bolt cutters. Tagout devices, by contrast, are prominent warning devices that an authorized employee fastens to energy-isolating devices to warn employees not to reenergize the machine while he or she services or maintains it. Tagout devices are easier to remove and, by themselves, provide employees with less protection than do lockout devices.

Target Audience 

This course introduces the importance of lock-out tag-out procedures as part of a safe system of work or permit to work. It’s a perfect overview for anyone new to LOTO and anyone with responsibility for the LOTO process

Course Content 

Outline the purpose and importance of LOTO:
• For controlling maintenance activities.
• Accident case studies.

Identify energy sources for common machinery and equipment:
• Stored vs residual.
• Electrical, mechanical, hydraulic, pneumatic, chemical, thermal.
• Capacitors, springs, elevated machine parts, flywheels, hydraulics, pneumatics, steam pressure, etc.

Outline common methods of isolation and LOTO devices:
• Isolators – electrical, mechanical, etc.
• Lock-out devices (where lockable energy isolator).
• Tag-out devices – where isolator cannot be locked.
• Single vs multiple LOTO.

Outline methods of dealing with stored energy: lockout tagout
• De-energise, restrain, disconnect, etc.

Outline the procedure for applying and removing LOTO: 
• The personnel/roles – authorised personnel (to assess, apply/remove LOTO).
• LOTO application – prepare for shut-down, shut-down, apply LO or TO devices to energy isolation
devices, treat stored energy, verify isolation.
• Consideration of isolation carried over several shifts (handover).
• LOTO release – inspect equipment, clear away essential personnel, remove LOTO devices, return to normal service.
