Breathing Air Quality Maziak Compressor Services

Breathing Air

EN12021:2014 regulates the air quality requirement for air used in breathing apparatus. It is the employer’s responsibility under the Health and Safety Executive to ensure that the air fed to its employees complies with this standard. Please find attached a BCAS fact sheet relating to this standard.

Breathing air can be used for a variety of applications, notably:

- Paint spraying

- Shot and bead blasting

- Asbestos removal

- Tank cleaning

- Chemical transportation

- Clean rooms and ventilation chambers

- Tunnelling, demolition

The typical compressed air requirement per person is dependent on the type of work carried out and the type of breathing air equipment used.
