Breathing Air Testing

Breathing Air Testing:

All employers have a duty of care to their employees to ensure that the breathing air they are supplied with is adequate for the respiratory protective devices (RPD) they are using and safe to breathe. We use the latest technology for testing, using the Factair F6000 safe air tester which ensures complete compliance with the relevant requirements of COSHH L5 in the UK. 

Breathing air testing to EN 12021 is required for all compressed air breathing applications. Compliance with EN 12021 ensures that the breathing air is safe and free from contaminants, protecting the health and safety of individuals who rely on it in their work.
