Lockout/Tagout (WAC 296-803)
A Lockout/Tagout program applies to employees who may be exposed to the potential release of hazardous energy from machines or equipment during activities that require bypassing safeguards to fix or maintain equipment. Hazardous energy may include electrical, mechanical, hydraulic, pneumatic, thermal, gravity, and other forms of energy. Lockout/tagout devices render machines and equipment inoperative, to enable employees to set-up, maintain and clean them without exposure to the hazards associated with the unexpected, inadvertent, or accidental operation of the equipment.
In wineries Lockout/Tagout procedures are often implemented when an employee, during set-up and maintenance activities, must bypass a machine guard or other safety device or must place a part of their body into the point of operation of the equipment. Examples of winery activities that may require Lockout/Tagout include:
- Bottling line maintenance
- Entering wine presses for maintenance or cleaning
- Entering wine tanks containing fixed mechanical devices
- Maintenance and trouble-shooting of electrical panels
A Lockout device uses a positive means, such as a key or combination lock, to hold an energy-isolating device in the "safe" or "off" position. A Tagout device is a prominent warning device, such as a tag and a means of attachment. It can be securely fastened to an lockout device to indicate warnings and who is working on affected equipment.
Exemptions to Lockout/Tagout include equipment that has a single energy source that can be controlled by the authorized employee (e.g. unplugging equipment and draining any stored energy before any maintenance or cleaning is done).
