Compressor Maintenance Hazards & Controls

Review the key hazards, consequences and control measures for Compressor Maintenance in a structured professional HSE format.

01
Hazard

Stored pressure

Potential Consequence

High-energy release

Persons at Risk

Maintenance personnel

Existing Controls

Depressurization and isolation

Additional Controls

Verify pressure indication at zero

02
Hazard

Contact with rotating parts

Potential Consequence

Entanglement or amputation

Persons at Risk

Maintenance workers

Existing Controls

Energy isolation and guarding

Additional Controls

Prevent re-energization while guards are removed

03
Hazard

Oil or process leakage

Potential Consequence

Slip, fire or exposure

Persons at Risk

Maintenance and nearby personnel

Existing Controls

Draining and spill control

Additional Controls

Verify leak source is eliminated after maintenance

04
Hazard

Residual pressure in compressor system

Potential Consequence

High-energy gas release

Persons at Risk

Maintenance workers

Existing Controls

Isolation and venting

Additional Controls

Verify zero pressure in all stages and receivers

05
Hazard

Hot compressor surfaces

Potential Consequence

Thermal burn

Persons at Risk

Maintenance personnel

Existing Controls

Cooling period and temperature verification

Additional Controls

Verify equipment has cooled to a safe temperature

06
Hazard

Automatic restart

Potential Consequence

Crushing or serious injury

Persons at Risk

Maintenance personnel

Existing Controls

LOTO and control-signal isolation

Additional Controls

Include remote and automatic start signals in isolation

07
Hazard

Residual compressed gas inside compressor

Potential Consequence

High-energy gas release

Persons at Risk

Maintenance personnel

Existing Controls

Venting and isolation system

Additional Controls

Existing Controls

Cooling period and temperature check

Additional Controls

Verify surface temperature has reduced to a safe level before maintenance

09
Hazard

Remote start signal remaining active

Potential Consequence

Unexpected startup and crushing

Persons at Risk

Maintenance personnel

Existing Controls

LOTO and control-signal isolation

Additional Controls

Include DCS and automatic start signals in the isolation scope
