Appendix 3 Quality of air for breathing apparatus 

 

 
Air quality 
 

1.

 

 Air supplied to breathing apparatus (BA) should be clean and safe to breathe, whether it is 
supplied via a fresh air hose or a source of compressed air.  

 
Fresh air hose 
 

 You should securely anchor the inlet for fresh air hose BA in an area that is free of contaminant. This 
can usually be achieved by siting the inlet well away from the work area (eg in free air outside the 
building), and upwind of any local sources of airborne contamination (eg vehicle exhaust).

 

 
 

Compressed air  

2.

 

 Compressed air for BA normally originates from a compressor system. The maintenance, 
examination and testing of compressors should be carried out according to the manufacturer’s 
instructions. The siting of air inlets to compressors should follow the same principles as for 
fresh air hose. However, because compressors themselves can generate and concentrate a 
wide range of contaminants, you should take extra care in assuring air quality.  
 

3.

 

As the BA wearer’s life and health depend on the air supplied by the compressor, you should 
ensure that the air supplied meets the quality requirements in British Standard BS EN 12021 
Respiratory protective devices. Compressed air for breathing apparatus,* in addition to the 
pressure and airflow rate requirements of the BA manufacturer.  
 

4.

 

Compressors which are moved from site to site, such as those used by the emergency services 
or on construction sites, will require a higher standard of maintenance and should be sited so 
that the quality of air they provide is not compromised by nearby contaminants.  

 
* BS EN 12021 states: ‘Compressed air for breathing apparatus shall not contain any contaminants at 
a concentration which can cause toxic or harmful effects. In any event all contaminants shall be kept 
to as low a level as possible and shall be far below the national exposure limit. Combination effects of 
more than one contaminant shall be taken into account.’ (1999)Respiratory protective equipment at 
work Page 48 of 59  
 

Periodic testing of air quality  

5.

 

 The purpose of periodically testing air quality is to make sure that the control measures you 
have put in place are delivering the air quality required by BS EN 12021. You should base the 
frequency of such tests on a risk assessment, but they should take place at least every three 
months, and more often when the quality of air cannot be assured to these levels.  

 

6.

 

 As part of the risk assessment, if a mobile compressor is being used consideration should be 
given as to how often the air supply should be checked when the compressor is moved. Testing 
for these components may be carried out using any appropriate method, eg:  

 

simple colour change tubes; 

 

on-line gas testers; 

 

sample collection for laboratory analysis elsewhere.
