Air Compressor Safety Inspection Template

What an air compressor safety inspection is

An air compressor safety inspection is a systematic periodic evaluation of a compressor system. You work through a defined set of checks to verify that the equipment is still operating safely, to identify hazards before they cause harm, and to keep the required compliance records in order. This template is built around a 31-point audit that you complete every time the compressor is due for review, so each inspection follows the same structure. Because compressed air systems run under pressure and involve moving components, leaks, and stored energy, a periodic review is the practical way to catch deterioration between services. The template covers four areas: equipment guarding and physical safety, leakage and equipment condition, maintenance and compliance records, and routine operations and environmental checks. Each question is answered **Yes**, **No**, or **N/A**.

Why it matters

A compressor that is not inspected can fail in ways that are easy to miss: a guard left off after maintenance, a pressure creeping above the safe working range, a slow oil leak, or an expired pressure test certificate. Each of these is a hazard to the people working near the unit and, in the case of expired certification, a compliance problem for the site. The inspection also protects continuity of operation. Daily draining of the air receiver and condensate lines, weekly checks of air leaks, oil levels, the belt guard, and water drainage, and a live operation log book are the routines that keep a compressor serviceable. The inspection is where you confirm they are actually happening. Keeping results consistent matters too. When every inspection follows the same numbered questions and the same answer options, you can compare one review against the next and see whether a problem was fixed or has returned.

What the inspection covers

**Equipment guarding and physical safety** - Protective guards and safety enclosures around moving components are properly secured in place. - The compressor is operating within its designated safe working pressure, as shown on the pressure gauge. - The compressor is housed in a secure, lockable area to prevent unauthorised access. - Combustible and flammable materials are stored outside the compressor's secure area. - The compressor is installed outside designated hazardous or explosive atmosphere zones. - The current operating pressure reading is recorded from the gauge. **Leakage and equipment condition** - The compressor unit, piping system, and fittings are free from oil leakage. - The compressor is in overall safe and serviceable working condition. - The manufacturer's identification plate is clearly visible and fully legible. - The overall physical condition of the compressor unit is rated. **Maintenance and compliance records** - The compressor is maintained in accordance with the manufacturer's specifications and guidelines. - It is serviced annually by a qualified technician. - Certificate of Compliance (COC) records are maintained for the annual and three-year pressure tests. - The three-year pressure test was conducted by a certified and licensed contractor. - The contractor's pressure vessel certification number (PV#) is kept on file. - The three-year pressure test certification is currently valid and not expired. - The certified contractor's name and licence number are recorded. **Routine operations and environmental checks** - The air receiver and condensate lines are drained daily. - Weekly checks cover air leaks, oil levels, belt guard, and water drainage. - Noise emission levels at the site boundary are within acceptable limits, with 45 dBa noted for built-up residential areas. - The compressor operation log book is available, current, and actively in use. - The measured noise level at the site boundary is recorded in dBa. A closing section captures the overall inspection result, any additional observations or recommended corrective actions, a signature, and the real start and end times of the inspection.

How to carry out the inspection

1. **Set up the record.** Record the date of the inspection, who is preparing it, and the location. This ties the completed audit to a specific machine and site. 2. **Start with guarding and pressure.** Before anything else, confirm the guards and enclosures are secured and that the compressor is running within the safe working pressure on its gauge. Note whether the unit is in a secure, lockable area, that no combustible or flammable materials are stored inside it, and that it is not sitting in a designated hazardous or explosive atmosphere zone. Write down the current pressure reading. 3. **Check condition and leakage.** Look over the compressor, its piping, and its fittings for oil leaks, and judge whether the unit is in safe and serviceable condition overall. Confirm the manufacturer's identification plate can be read clearly, and give the unit an overall condition rating. 4. **Review the paperwork.** Check that maintenance follows the manufacturer's specifications and that annual servicing by a qualified technician has taken place. Confirm Certificate of Compliance records exist for both the annual and three-year pressure tests, that the three-year test was done by a certified and licensed contractor, that the contractor's pressure vessel certification number (PV#) is on file, and that the certification has not expired. Record the contractor's name and licence number. 5. **Verify the routine checks.** Confirm the air receiver and condensate lines are drained daily and that weekly checks are being carried out for air leaks, oil levels, the belt guard, and water drainage. Check the operation log book is available, current, and in use. Measure and record the noise level at the site boundary in dBa, comparing it against the acceptable limit. 6. **Close the inspection.** Record the overall result, note any additional observations, concerns, or recommended corrective actions, sign the record, and enter the real start and end times. Answer **N/A** only where a question genuinely does not apply to the unit or site you are inspecting.

Frequently Asked Questions

A good air compressor safety inspection covers four broad areas. First, guarding and physical safety: protective guards and enclosures around moving components are checked to confirm they are secured, the compressor is confirmed to be operating within the safe working pressure shown on its pressure gauge, it is housed in a secure, lockable area to prevent unauthorised access, and combustible or flammable materials are kept outside that area. Second, leakage and equipment condition: the unit, piping, and fittings are checked for oil leaks, the compressor's overall safe and serviceable condition is assessed, and the manufacturer's identification plate is checked for clear visibility and legibility. Third, maintenance and compliance records: maintenance against the manufacturer's specifications is verified, annual servicing by a qualified technician is confirmed, and Certificate of Compliance records covering the annual and three-year pressure tests are checked, including the certified and licensed contractor who carried out the three-year test, the contractor's pressure vessel certification number (PV#), and whether the current three-year test certification is valid and unexpired. Fourth, routine operations and environmental checks: daily draining of the air receiver and condensate lines, weekly checks for air leaks, oil levels, belt guard condition and water drainage, noise levels at the site boundary, and a compressor operation log book that is available, current and in active use.

The template asks for a pressure test certificate. Specifically, it checks that Certificate of Compliance (COC) records are maintained for the annual and three-year pressure tests, that the three-year pressure test was conducted by a certified and licensed contractor, that the contractor's pressure vessel certification number (PV#) is recorded and kept on file, and that the certification is currently valid and not expired. It also records the certified contractor's name and licence number.

Write down each answer as you go. The template begins by recording the inspection date, the person preparing it, and the location. You then work through the questions covering guarding and physical safety, leakage and equipment condition, maintenance and compliance records, and routine operations and environmental checks, ticking Yes, No or N/A against each and recording the current pressure gauge reading. At the end you record the noise level at the site boundary, the overall inspection result, any additional observations or recommended corrective actions, your signature, and the real start and end times of the inspection.

Yes. Daily draining of the air receiver and condensate lines is part of the inspection, as are weekly maintenance checks for air leaks, oil levels, the belt guard, and water drainage. The compressor operation log book is also checked to confirm it is available, current, and actively in use. This means the record is a continuous one, not something put together only when an inspection is due.
