About this file
This document is a Job Hazard Analysis (JHA) for a pump changeout activity at Lake Mead National Recreation Area, prepared by Arthur Samons and certified by Ben R. Smith on 5/9/2025. The JHA details safety procedures for disconnecting electrical sources, isolating hydraulic energy, and removing old pumps, with specific focus on preventing electrocution, shock hazards, and tripping risks. Required personal protective equipment includes safety glasses and gloves, and personnel must be trained in proper Lockout/Tagout (LOTO) procedures.
The JHA outlines three primary job steps: disconnecting power from the electrical source, closing valves to isolate pump hydraulic energy, and removing pumps from their location. Each step includes identified hazards and corresponding safe job procedures, such as using electrical breakers, checking voltage with a meter, shutting control valves, and removing old pumps to eliminate tripping hazards. The document is part of a federal contract opportunity (Solicitation Number 140P8125Q0016) for replacing pumps at multiple locations within Lake Mead NRA, involving a total of twelve pumps across Katherine Landing, Callville Bay, and Echo Bay.

CERTIFIED BY: Ben R. Smith
PERSONAL PROTECTIVE EQUIPMENT REQUIRED: List Type
Safety glasses, gloves.
QUALIFICATIONS, EXPERIENCE, OR TRAINING REQUIRED:
Must be trained in proper LOTO procedures.
BASIC JOB STEPS HAZARDS SAFE JOB PROCEDURE
Break work down to basic elements (such as remove, lift, carry, stop, start, apply, return, squeeze, weld, saw, walk, hold, grind, place, etc.). Describe what is done, not how it is done.
For each job step, state what accident could occur and/or what hazard is present. To determine this, ask yourself, “can the person fall; overexert; be exposed to burns, fumes, rays, gas, etc.; hit against; be struck by; in contact with; be caught in, on, or between?”
State how each element of work should be performed to prevent the accident or avoid the hazard. What should the person do or not do? Be specific. What precautions should be taken? Ask yourself, “What can I do to eliminate, modify, guard, identify, or protect against the potential hazard or accident, including such things as how the worker stands, holds, uses, carries, dresses, etc.?”
Disconnect power from electrical source.
Close valves to isolate pump from hydraulic energy.
Remove pump from location.
Electrical must be disconnected to prevent electrocution and shock hazards.
Valves must be closed to prevent the possibility of injury from water pressure being released unexpectedly.
Old pumps must be removed from area to prevent tripping hazard.
Use electrical breaker or disconnect to isolate pump motor from electrical current. Must be checked with voltage meter to be sure. LOTO
Ensure pumps are isolated from hydraulic energy be shutting control valves on piping connected to pumps. Use LOTO.
Remove old pumps from plant floor to ensure the work area is clear and free of tripping hazards.
