Study Notes
Lockout Tagout Overview
- Lockout tagout (LOTO) ensures machines are disabled during servicing to prevent injury.
- Involves isolating machinery from its energy source using locks, tags, and devices.
- Situations for LOTO include repairs, cleaning, lubrication, and maintenance tasks.
OSHA Regulations
- OSHA mandates energy control programs in all facilities to include written LOTO procedures.
- Programs must detail procedures for all powered equipment and machinery.
- Employee training on LOTO procedures is essential.
Equipment and Devices
- Common LOTO devices include padlocks, chains, valve clamps, wedges, and pins.
- Tag devices provide visual warnings but should not replace locks for securing energy isolation.
- LOTO devices must be clearly identifiable and durable for harsh conditions.
Authorized Personnel
- Only specific employees are authorized to install LOTO devices.
- Employees must recognize hazardous energy sources and understand control procedures.
- Affected employees must be informed of ongoing LOTO operations but cannot restart machines.
Lockout Procedures
- Notify all necessary personnel before starting LOTO.
- Lock out and tag energy sources using proper mechanisms for electrical panels and valves.
- Central storage for LOTO equipment may exist in facilities, with a sign-in log for accountability.
Energy Types
- Common energy sources: electrical, hydraulic, and pneumatic.
- Each energy source has active (in use) and stored (awaiting use) states.
- Safe procedures often involve dissipating stored energy, such as draining hydraulics or grounding electrical systems.
Testing and Verification
- After LOTO, test machines to ensure they do not operate using voltmeters and operational tests.
- Return all controls to off positions before beginning maintenance.
Special Situations
- For personnel changes, incoming shift workers must install their LOTO devices before removing those of the outgoing shift.
- Consult supervisors for LOTO when multiple machines share the same energy source or when essential equipment cannot be deactivated.
Arc Flash Awareness
- Arc flashes are explosive electrical incidents caused by short circuits; they pose severe risks.
- Work areas with arc flash potential are marked with warning labels.
- Proper supervision and established procedures are required when working in these high-risk areas.
Group Lockout and Contractor Involvement
- The buddy system is recommended for monitoring LOTO procedures when power sources are out of sight.
- Group lockout devices must be used for multiple workers, ensuring each member has their own lock.
- Contractors must be informed of ongoing LOTO activities and keep communication open if they partake in such operations.
Lockout Tagout Release Procedures
- Before resuming operation, remove tools from the area and ensure all employees are clear.
- Each worker who attached a lock must remove their own before the machine can return to service.
- In emergencies, management can remove devices if original employees cannot be contacted.
Electrical, Hydraulic, and Pneumatic Systems
- For electrical systems, identify energy sources and shut off equipment at operation points to prevent explosions.
- In hydraulic and pneumatic systems, use pads, chains, and blinds to isolate valves and prevent high-pressure releases.
- Secure heavy moving parts to prevent movement during lockout from external disturbances.
Summary of Best Practices
- Always identify all energy sources before beginning work.
- Each worker must apply their own lockout device.
- Test equipment post-lockout to ensure safety before operation.
- Effective communication and understanding of LOTO procedures are critical for safety in powered equipment servicing.
Lockout Tagout Overview
- Lockout tagout (LOTO) is crucial for disabling machinery during service to prevent injuries.
- Process involves isolating machinery from energy sources using locks and tags.
- Applicable in various situations such as repairs, cleaning, lubrication, and maintenance tasks.
OSHA Regulations
- OSHA requires all facilities to implement energy control programs that include written LOTO procedures.
- Procedures must be comprehensive, covering all powered equipment and machinery.
- Training for employees on LOTO protocols is mandatory for safety compliance.
Equipment and Devices
- Typical LOTO devices include padlocks, chains, valve clamps, wedges, and pins.
- Tag devices indicate hazards but do not replace locks for securing energy isolation.
- Devices used must be identifiable and designed to withstand harsh conditions.
Authorized Personnel
- Only designated employees are permitted to install LOTO devices.
- Authorized personnel must be aware of hazardous energy sources and control procedures.
- Affected employees must be informed of LOTO operations but are not authorized to restart machinery.
Lockout Procedures
- Inform necessary personnel before initiating LOTO procedures.
- Proper locking and tagging of energy sources are essential for safety.
- Facilities may have central storage for LOTO equipment with a sign-in log.
Energy Types
- Common energy sources include electrical, hydraulic, and pneumatic.
- Energy sources can be categorized as active (in use) or stored (awaiting use).
- Safe practices often require dissipating stored energy, such as draining hydraulics or grounding electrical systems.
Testing and Verification
- Post-lockout, test machines to confirm they do not operate, utilizing voltmeters and operational checks.
- Ensure all controls are returned to the off position prior to maintenance activities.
Special Situations
- Incoming shift workers must apply their own LOTO devices before removing those from outgoing workers.
- Supervisors should be consulted for LOTO procedures involving multiple machines sharing energy sources or for essential equipment that cannot be deactivated.
Arc Flash Awareness
- Arc flashes are dangerous electrical incidents caused by short circuits, resulting in severe risks.
- Areas where arc flash potential exists should be clearly marked with warning labels.
- Proper supervision and adherence to established procedures are critical in these hazardous environments.
Group Lockout and Contractor Involvement
- The buddy system is recommended to monitor LOTO when power sources are out of sight.
- Group lockout devices are required for teams, allowing each member to attach their own lock.
- Contractors must be informed of LOTO activities and maintain open communication about safety procedures.
Lockout Tagout Release Procedures
- Before machine operation resumes, remove tools and ensure all personnel are clear from the area.
- Each worker must remove their own lock for the machine to be operational again.
- In emergencies, management can remove locks if original workers cannot be reached.
Electrical, Hydraulic, and Pneumatic Systems
- For electrical systems, clearly identify energy sources and shutdown equipment at control points to prevent hazards.
- In hydraulic and pneumatic systems, utilize devices like pads and chains for valve isolation to prevent pressure releases.
- Secure heavy moving components to prevent unintended movements during lockout situations.
Summary of Best Practices
- Identify all energy sources prior to work commencement.
- Each worker must individually apply their lockout device.
- Ensure thorough testing of equipment after lockout for safety before operation.
- Effective communication and comprehension of LOTO procedures are critical for safe equipment servicing.
