Why Is Welding Fume Testing Required?
Under the Control of Substances Hazardous to Health (COSHH) Regulations, employers are legally required to assess, monitor, and control exposure to welding fumes, which are classified as a cause of occupational lung disease and cancer.
Testing must verify that:
- Your LEV system captures fumes effectively
- Respiratory protection equipment is inspected and maintained
- Controls are in good working order and condition
- Exposure remains within the Workplace Exposure Limits (WELs)
What’s Included in Our Weld Fume Testing
Our welding fume testing service includes:
- On-site assessment of extraction (LEV) and filtration systems
- Capture velocity measurements (0.5–1 m/s range per HSE guidance)
- Flow rate testing for on-torch extraction (vs. manufacturer specs)
- Visual inspections for seal integrity and fume dispersion
- Testing and recording of RPE condition and function
- Detailed report and certification for compliance purposes
✅ Our engineers are trained to P601 and P602 standards.
Testing Methods for Different Welding Types
| Welding Type | Assessment Method |
|---|---|
| MIG/MAG, Stick | Capture velocity and qualitative observation (video if needed) |
| TIG | Dust lamp or tracer smoke to assess invisible fume behaviour |
| On-torch | Airflow/volume flow rate test (not velocity) |
| Enclosed Booths | Smoke clearance or LEV effectiveness test |
We tailor each test to match your specific process and layout.
How Often Should You Test?
According to HSE and COSHH guidelines, you must:
- Test LEV systems at least every 14 months
- Check RPE before each use and maintain regular records
- Carry out exposure monitoring when changes in process or ventilation occur
We offer one-off tests, multi-point system inspections, or bundled LEV + RPE + smoke clearance tests.

Would definitely recommend C-Air filtration for all LEV works. Thanks for the great service.

After struggling to source the filters for some time (with other companies) I tried C-Air Filtration. Their prompt service delivered me a quote for the filters very quickly, and gave me in-depth bespoke advice on filter change procedures for the specific filter in question such as dealing with the safe-change bags etc.
After processing the quote the filters came, well within the lead time. They were the correct specification and size.
Brilliant service, I would highly recommend.

Very good company to purchase our goods from. Quick responses and replies to any emails sent if updates on our order(s) are required. Turnaround time from order to delivery is very good (within just a couple of days from PO being sent) - fast service. Goods are well packed and securely strapped or wrapped to pallets upon arrival.
