HTM 2022 and Clinical Air Standards
Health Technical Memorandum 2022 (HTM 2022) sets high standards for the quality of clinical air used in Health Authority premises. Private dental practices are not legally required to conform, but proficient dentists should take on board and implement its recommendations to promote best practice and protect patients.
When a compressor is delivering adequate air, it is easy to become complacent and compromise clinical performance. Other high-profile items may take priority over regular air checking and routine maintenance, which in turn could increase the risk of harming a patient.
The Risks of Oil-Dependent Compressors
In many dental surgeries, an oil-dependent compressor sits at the centre of the compressed air system. Without regular specialist attention, the pressure chamber can be penetrated by up to 1% of oil over time. This oil reacts with moisture in the air, creating an emulsion that becomes an ideal breeding ground for dangerous bacteria.
Unless a specialist engineer is adhering to a fastidious maintenance programme, these bacteria can make their way into a patient's mouth, causing a range of infections from gastro-enteritis to Legionnaire's disease.
The key risks include:
- Oil contamination of the air supply, creating conditions for bacterial growth
- Moisture accumulation in pipework and receivers, compounding the contamination risk
- Inadequate filtration allowing particulates to reach clinical instruments
- Lack of regular air quality testing to identify problems before they reach patients
Modern Compressor Technology
Thankfully, these risks are now largely eradicated by the latest generation of compressors, which are no longer oil-dependent. Oil-free compressors deliver clean, dry air without the risk of oil carry-over into the clinical air supply.
New compressor technology, coupled with the HTM 2022 standards, makes now an ideal time for dental practices to review their compressed air system and associated dryers, filters, and pipework. Whether your practice is considering a new installation or simply needs to assess the quality of its current air supply, a thorough review can protect both patients and practitioners.
