Study Notes
Standard Operating Procedure (SOP) for Deenergizing Machinery
- Systematic deenergizing is essential for protecting personnel during maintenance or repair work.
- This procedure addresses unintentional machine operation while space is shut down.
- Unit Officers-in-Charge (OICs) can modify procedures based on special or unusual circumstances.
Equipment Usage
- Lock out/tag out (LOTO) equipment must be maintained on designated Technical Rescue Technician units.
- Specific units with LOTO equipment include:
- Aerial 43 (South Miami-Dade County)
- Ladder 46 (Northwest Miami-Dade County)
- Aerial 19 (Northeast Miami-Dade County)
- Squad 69 (Central Miami-Dade County)
- Additional LOTO equipment available on Hazmat Support units:
- L-17
- E-56
- E-63
- L-59
- Hazmat 69
Isolation and Safety Guidelines
- Prior to entry into hazardous spaces, proper isolation using the LOTO system must be performed.
- If locking is not possible for environmental control devices, physical security must be ensured.
Responsibilities
- The Incident Commander (IC) bears ultimate responsibility for isolating all spaces before entry.
- The TRT Group Safety Officer and Entry Officer must individually verify isolation and apply locks.
- A minimum of two locks are required on each device to prevent unauthorized re-energization.
- Entrants can place their own locks on devices to ensure personal safety.
Prohibited Device Operations
- All types of devices must be disconnected, restrained, and locked in the "off" position:
- Electric
- Pneumatic
- Hydraulic
- Mechanical
- Spring wound
- Gravity controlled
- A minimum of two padlocks must secure each device, along with appropriate tagging.
Team Procedures
- Entry Team retains possession of the Entry Officer's key until they exit the confined space.
- Ensures entry team exit before removing any LOTO devices.
- Collaboration with experts (plant managers, utility services) is crucial for effective isolation.
Post-Work Evaluation
- After work completion, the IC, TRT Group Safety Officer, and Entry Officer evaluate safety before removing locks.
- Area must be deemed safe before returning control to the responsible party.
- Completion of MDFR National Fire Incident Reporting System (NFIRS) report necessary before shift end.
