Industrial Air Compressor Plant Safety Checklist

Verify air receiver ASME nameplate indicates a pressure rating exceeding the compressor's maximum discharge pressure.

Confirm the air receiver has undergone a hydrostatic test within the last 5 years, documented with a valid test certificate.

Inspect the air receiver exterior for signs of corrosion, pitting, or damage; document findings with photos.

If accessible, perform an internal inspection of the air receiver for corrosion and scale buildup; document findings.

Check the air receiver supports for structural integrity, ensuring they are securely anchored and free from corrosion.

Verify the air receiver drain valve operates freely and completely drains accumulated condensate.

Confirm the air receiver pressure gauge is accurate within +/- 2% of the actual pressure, using a calibrated test gauge.

Ensure the pressure relief valve (PRV) has sufficient CFM capacity to relieve the compressor's maximum output.

Verify the PRV setpoint is at or below the air receiver's maximum allowable working pressure (MAWP).

Confirm the PRV has been tested within the last 12 months and is documented with a valid test certificate.

Ensure the PRV discharge is piped to a safe location, away from personnel and equipment.

Check the air compressor oil level and ensure it is within the manufacturer's recommended range.

Inspect the air compressor for oil leaks around seals, fittings, and gaskets; repair as needed.

Examine the air compressor air filter and replace if dirty or clogged.

Verify the air compressor cooling system (air or water) is functioning correctly and free from obstructions.

If applicable, check the air compressor belt tension and adjust as needed to prevent slippage.

Monitor the air compressor discharge temperature and ensure it is within the manufacturer's recommended range.

Verify the aftercooler is functioning correctly to reduce air temperature and moisture content.

Inspect condensate traps for proper operation; ensure they are discharging condensate effectively.

Monitor air compressor vibration levels; investigate and correct any excessive vibration.

Inspect all electrical connections for tightness and signs of corrosion; tighten or replace as needed.

Test the air compressor emergency shutdown system to ensure it functions correctly.

Verify all air lines are rated for the maximum operating pressure of the system.

Ensure air line materials are compatible with the compressed air and any additives (e.g., oil).

Inspect all air lines for leaks using a soap solution or ultrasonic leak detector; repair leaks immediately.

Verify air lines are properly supported with adequate spacing to prevent sagging or stress.

Ensure all air lines are clearly identified with their contents and pressure rating.

Inspect flexible air line connections for wear, damage, or kinks; replace as needed.

Check quick-disconnect fittings for proper locking and sealing; replace if damaged.

Ensure safety whips are installed on all air hoses to prevent whipping in case of hose failure.

Verify all metallic air lines are properly grounded to prevent static electricity buildup.

Ensure air lines are routed to avoid physical damage from traffic, equipment, or other hazards.

Verify air lines are sloped to allow for proper drainage of condensate.

Conduct noise level monitoring around the air compressor plant to ensure compliance with OSHA permissible exposure limits (PELs).

Ensure appropriate hearing protection (earplugs or earmuffs) is readily available for personnel working in high-noise areas.

Verify personnel are using hearing protection correctly in designated high-noise areas.

If noise barriers are in place, inspect them for damage or deterioration and ensure they are effectively reducing noise levels.

Check vibration dampening mounts on the air compressor to ensure they are in good condition and effectively reducing vibration transmission.

Verify adequate ventilation is provided to prevent the buildup of heat or fumes in the air compressor plant.

Ensure oil spill containment measures are in place to prevent environmental contamination in case of leaks or spills.

Verify waste oil is being disposed of properly in accordance with environmental regulations.

If the air compressor is enclosed, check the enclosure for proper ventilation and access for maintenance.

Ensure appropriate signage and warnings are posted in the air compressor plant, including noise hazard warnings and PPE requirements.

Verify up-to-date operating procedures for the air compressor plant are readily available and accessible to all personnel.

Review maintenance records to ensure regular maintenance is being performed on the air compressor and associated equipment.

Review previous inspection reports to identify any recurring issues or trends.

Verify all personnel working in the air compressor plant have received adequate training on safe operating procedures and emergency response.

Ensure an emergency response plan is in place for the air compressor plant, including procedures for responding to fires, leaks, and other incidents.

Verify lockout/tagout procedures are in place and being followed for all maintenance and repair work on the air compressor and associated equipment.

Confirm that pressure vessel inspection records are current and readily available for review.

Verify that pressure relief valves have current certifications and are properly documented.

Ensure that Material Safety Data Sheets (MSDS) or Safety Data Sheets (SDS) are readily available for all chemicals used in the air compressor plant.

Verify that the air compressor plant is adequately secured to prevent unauthorized access.
