Air Compressor Permits
California requires permits for almost all air compressors used by businesses. The regulation, CCR 8 Section 450 et seq., (www.dir.ca.gov/title8/sub1.html.) is not specific to dentistry.
Inspectors from the Cal/OSHA Pressure Vessel Unit (www.dir.ca.gov/dosh/pressure.html) conduct safety checks on compressors for the purpose of issuing and renewing permits only. They do not inspect the workplace for compliance with other Cal/OSHA regulations. The safety inspection of the compressor should not interfere with the normal operations of a dental office. Inspectors use an ultrasonic device to measure thickness of the steel and compare it with the information on the name plate. If drain and dryer on a compressor are not working properly, the steel on the tank can rust. Inspectors ensure the compressor and all its parts function. They ensure safety relief valve, manual drain, and pressure gauge are present and functioning. They check for leaking, cracked, or defective tanks and ensure there are no electrical problems. Schedule 80 pipe is required from tank to the first stop valve in both directions. PVC piping not allowed; oil and sunlight make the plastic brittle.
The stated cost is $135/hr for inspection, travel and administration. In practice, inspectors schedule visits to several businesses in a day, then charge each business an equal share of the day’s inspection, travel and administrative charge. Each tank permit is $15 for a term of 5 years. Inspections can be scheduled by calling the Northern California office in Oakland, 510.622.3066, or Southern California office in Santa Ana, 714.567.7297, of the Cal/OSHA Pressure Vessel Unit. Due to a staff shortage in the department, inspections may not occur on a timely basis. The Pressure Vessel Unit does send out letters confirming a business’ request for inspection. This letter is adequate proof of intent to comply with the regulation, should a business be inspected by Cal/OSHA Enforcement staff.
Inspections of air compressors can be conducted by other state-certified inspectors. However, these other inspectors are usually employed by risk insurance companies who offer the inspection service to their clients. Dental practices do not typically carry risk insurance, and it is unlikely that an insurance company would provide a service to a non-client.
