Cost-effective, certified breathing air quality testing for spraybooths, prep bays, and workshop compressed air lines across the UK. Available as standalone testing or integrated into an annual compliance management plan.

We provide comprehensive breathing air testing to ensure your air-fed respiratory protective equipment (RPE) delivers clean, safe, and breathable air at every outlet. Our service removes the compliance burden from your team: we conduct precision testing, handle remedial filter replacements, track statutory re-test deadlines, and supply full documentation to satisfy HSE inspectors and insurance audits.

Why Breathing Air Testing Is Mandatory (BS EN 12021 & COSHH)

Compressed air used for breathing apparatus must comply with the strict purity thresholds set out in BS EN 12021, alongside the Management of Health and Safety at Work Regulations, PPE at Work Regulations, and the Control of Substances Hazardous to Health (COSHH).

Under current guidance, breathing air quality tests must be completed at least once every 3 months (or more frequently if indicated by your site risk assessment). Our calibrated testing equipment evaluates critical contamination parameters on-site, including:

• Carbon Monoxide (CO) & Carbon Dioxide (CO₂): Detecting dangerous compressor combustion bypass or ambient intake contamination.
• Oil Mist & Particulates: Verifying coalescing filtration efficiency to prevent lung exposure to compressor lubricants.
• Water Vapour & Dew Point: Ensuring air lines are sufficiently dry to prevent condensation, regulator icing, and microbial growth.
• Oxygen Content: Confirming oxygen levels remain strictly within the compliant 20.9% (±0.5%) atmospheric range.
• Odour & Taste: Verifying delivered air is completely neutral and safe for continuous operator use.

Fast On-Site Testing with Minimal Workshop Downtime

Our experienced service engineers use dedicated electronic and chemical reagent test instruments to sample each air point in approximately 30 minutes. We schedule visits around your spray schedules to prevent operational bottlenecks. Testing multiple points allows us to immediately isolate line-specific filter failures or compressor issues. Following the test, you receive a full BS EN 12021 Certificate of Thorough Examination detailing all test readings for your statutory COSHH compliance records.

The All-in-One Compliance Visit

Avoid coordinating multiple contractors and paying separate call-out fees by bundling your legal safety checks into a single site visit. Our engineers can carry out your Quarterly Breathing Air Quality Check (BS EN 12021), Annual LEV Thorough Examination (COSHH Reg 9), and Spraybooth Smoke Clearance Time Test on the exact same day. We handle the scheduling, provide synchronized reminder alerts, and supply consolidated digital certification to keep your workshop audit-ready at lower overall cost.
