Let’s dive into practical solutions that’ll help you create a safer welding environment. We’ve gathered proven techniques and best practices to help you meet UK safety regulations whilst protecting your team’s wellbeing.
Welding fumes create a complex mixture of airborne particles metals gases that pose significant health risks to workers. These hazards vary based on the welding process type of metals involved.
Welding operations generate several types of harmful fumes:
| Welding Process | Primary Fume Components | Concentration Level (mg/m³) |
|---|---|---|
| MIG/MAG | Iron Oxide, Manganese | 5-10 |
| TIG | Tungsten, Argon | 2-5 |
| Stick | Iron, Silica | 10-15 |
The HSE identifies specific health impacts from welding fume exposure:
| Health Effect | Time Frame | Required Action |
|---|---|---|
| Metal Fume Fever | 4-12 hours | Immediate ventilation |
| Respiratory Issues | Long-term | Regular health surveillance |
| Cancer Risk | 10+ years | Prevention through control measures |
Engineering controls form the primary defence against welding fume exposure in UK workshops. These measures create systematic barriers between workers and hazardous fumes through targeted extraction methods.
Local Exhaust Ventilation (LEV) systems capture welding fumes at their source before they reach the welder’s breathing zone. These systems include fixed extraction arms mounted near welding stations, downdraft tables for bench work, and portable extraction units for mobile welding tasks. The extraction hood placement sits 200-300mm from the welding point to maximise fume capture efficiency.
Key components of an effective LEV system:
On-torch extraction integrates fume capture directly into the welding torch design. These systems remove fumes within 100mm of their generation point, providing immediate protection for welders.
Essential features include:
Performance indicators:
| Feature | Specification |
|---|---|
| Capture velocity | 0.5-1.0 m/s |
| Operating distance | 50-100mm |
| Extraction rate | 80-150 m³/h |
| Filter efficiency | 99.9% at 0.3μm |
At Norsemen safety we stock the MIG air cooled fume extraction by Holch.
This torch keeps the air in the workspace clean and safe, it eliminates harmful fumes, gases and particles created during welding allowing for a safer and healthier work environment.
Personal protective equipment (PPE) forms an essential layer of protection for welders against harmful fumes and particulates. The Health and Safety Executive (HSE) mandates specific PPE requirements for welding operations in the UK.
Powered Air-Purifying Respirators (PAPRs) provide the highest level of respiratory protection for welders. These systems include:
Traditional respirators offer alternative protection options:
Comprehensive welding protection extends beyond respiratory equipment:
Protective Clothing:
| PPE Type | Protection Level | Replacement Frequency |
|---|---|---|
| PAPR | 99.95% (P3) | Filters: 3 months |
| Half-mask | 94-99% (P2-P3) | 6 months |
| FFP3 | 99% | Single use |
| Welding Helmet | UV/IR Grade 11-13 | 2 years |
Effective workplace design coupled with proper ventilation systems creates a safer welding environment by controlling fume exposure at the source. Strategic layout planning maximises natural airflow while mechanical ventilation supplements air circulation in enclosed spaces.
Natural ventilation leverages outdoor air movement through strategically placed openings to disperse welding fumes. Opening windows at opposite ends of the workspace creates cross-ventilation patterns that direct fumes away from welders’ breathing zones. High-level roof vents or skylights encourage the stack effect, allowing hot fumes to rise naturally upward. We recommend positioning welding stations near building openings while maintaining appropriate distances from walkways to prevent fume drift into occupied areas.
Mechanical ventilation systems provide controlled air movement when natural ventilation proves insufficient. Down-draft tables pull fumes downward through perforated surfaces, ideal for small component welding. Ceiling-mounted extraction arms offer flexible positioning with 3-4 metre reach to capture fumes directly above welding points. Push-pull systems combine supply air with exhaust ventilation to create directional airflow patterns across large work areas. Key specifications for mechanical systems include:
| Component | Specification |
|---|---|
| Minimum Air Changes | 6-10 per hour |
| Capture Velocity | 0.5-1.0 m/s |
| Duct Transport Velocity | 10-20 m/s |
| Filter Efficiency | 99.5% at 0.3 microns |
| Fan Power | 1.1-2.2 kW per station |
At Norsemen Safety we recommend the Portable Welding Fume extractor for your mechanical Ventilation needs.
This Portable Welding Fume Extractor is ideal for environments with medium to low concentrations of airborne pollutants, it is specifically designed for enclosed or hard-to-access areas where traditional systems don’t suffice.

Welding fumes are complex mixtures of airborne particles, metals, and gases produced during welding processes. They’re dangerous because they contain toxic substances like metal oxides, carbon monoxide, and nitrogen oxides that can cause both immediate health issues (eye irritation, breathing problems) and long-term conditions (occupational asthma, lung cancer).
LEV systems are engineered solutions that capture and remove welding fumes at their source before workers can breathe them in. They consist of capture hoods, ducting networks, air filters, and exhaust fans. When properly maintained, LEV systems are the most effective engineering control for protecting welders from harmful fumes.
Powered Air-Purifying Respirators (PAPRs) offer the highest level of protection, featuring filtered air delivery units and full-face masks with P3 filters that capture 99.95% of airborne particles. Alternative options include half-mask respirators and disposable FFP3 masks, all of which require proper face-fit testing.
Safety equipment should undergo regular inspections: daily checks for PPE, monthly testing for air quality and respirators, and annual thorough examinations for LEV systems. Equipment maintenance schedules should be documented and followed strictly to ensure optimal protection for workers.
Welders require comprehensive training in hazard recognition, PPE selection and use, LEV operation, and emergency response protocols. They must complete COSHH awareness training and face-fit testing certification. Regular refresher courses are essential to maintain safety standards and competency.
Effective workplace design incorporates proper ventilation systems, including natural cross-ventilation and mechanical solutions like down-draft tables and ceiling-mounted extraction arms. The layout should facilitate good air flow and include dedicated welding areas with appropriate fume control measures.
Essential PPE includes respiratory protection (minimum FFP3), flame-resistant clothing, heat-resistant gloves, steel-toed safety boots, and auto-darkening welding helmets with UV-protective face shields. All PPE must meet current HSE standards and be properly maintained.
Regular air quality monitoring, including monthly air sampling for respirable particulates and specific gas detection, helps assess the effectiveness of control measures. Visual inspections of LEV systems, along with worker feedback and exposure monitoring, provide comprehensive evaluation of control measures.
