Industrial Fume Testing UK

UK manufacturers must comply with several key regulations governing indoor air quality and workplace safety:

• Health and Safety at Work Act 1974: Legal duty to ensure safe working conditions
• COSHH Regulations: Control of substances hazardous to health
• Workplace Exposure Limits (EH40/2005): Maximum concentrations of airborne substances
• Building Regulations Part F: Ventilation requirements for buildings
• BESA TR19: Ductwork cleaning and hygiene standards

Manufacturers must conduct regular air quality assessments, maintain ventilation systems, and document compliance to protect workers and avoid enforcement action.

Manufacturers face specific air quality challenges that require specialist expertise:

• Process emissions: Fumes, dust, and chemical vapours from production activities
• Local Exhaust Ventilation (LEV): Systems that capture contaminants at source
• Industrial ventilation: High-volume air handling for large facilities
• Workplace Exposure Limits: Regular monitoring to ensure compliance with EH40 standards
• Equipment maintenance: Scheduled servicing to maintain extraction performance

We provide testing, validation, and maintenance services designed specifically for industrial environments to ensure regulatory compliance and worker safety.

Manufacturing facilities must conduct regular air quality testing to demonstrate compliance:

• Workplace Exposure Limit (WEL) testing: At least annually, or when processes change
• LEV examinations: Every 14 months under COSHH regulations
• TM44 inspections: For air conditioning systems over 12kW, every five years
• Ductwork cleaning: According to TR19 guidance, typically every 12-24 months
• Fire damper testing: Annually under BS 9999 requirements

We recommend continuous monitoring in high-risk areas to identify issues before they affect compliance or worker health.

Failure to maintain compliant air quality can result in significant consequences:

• Enforcement notices: HSE improvement or prohibition notices halting production
• Financial penalties: Fines for breaches of health and safety legislation
• Worker health issues: Respiratory conditions, reduced productivity, and increased absence
• Legal liability: Claims for occupational illness or injury
• Reputational damage: Loss of contracts and difficulty recruiting skilled workers

Regular assessment and maintenance of ventilation systems protects both your workforce and your business operations.

We support manufacturers through our Assess, Remediate, and Maintain framework:

• Assessment services: WEL (EH40) Testing, LEV Examinations, IAQ Monitoring, TM44 Inspections, Airflow Testing
• Remediation services: LEV Installation and Upgrades, HVAC Repairs, AHU Servicing, Ventilation System Design
• Maintenance services: Ductwork Cleaning (TR19), Fire Damper Testing (BS 9999), Filter Replacements, Scheduled LEV Maintenance

This comprehensive approach ensures no gaps in compliance, protecting your workers and maintaining uninterrupted production.

Yes, fumes produced when welding are toxic, containing pollutants such as ozone, nitrogen oxides, and particulate matter, which can cause irritation to the respiratory tract and cause headaches. 

Working in poorly-ventilated spaces can heighten this effect and lead to increased personal exposure. Heat produced from welding can also contribute towards nausea and headaches, if temperatures are not properly managed.

Some metalworkers report 'metal fume fever' due to inhalation of metal particles, leading to various health complications.

Welding fumes are limited by HSE in EH40 (WELs), but it is the responsibility of the employer to identify the relevant pollutants individually and assess the concentrations.

Indoor air quality monitors can be deployed within your metalworking space to check whether workers are exposed to dangerous levels of pollution from welding fumes. If you're worried about the exposure of metal welding fumes to you or your staff, get in touch as soon as possible to avoid further health risks.

Health symptoms from inhalation of exhaust fumes depend on the mixture and concentration of pollutants present. Exposure to car or generator exhaust can cause symptoms such as headaches, dizziness, nausea, and fatigue. These effects are primarily associated with gases such as carbon monoxide (CO) and nitrogen oxides, as well as fine particulate matter.

If you're worried that inhaling exhaust fumes is having an effect on the health of you or your workers, get in touch immediately to book an air quality assessment. This will tell you exactly what you're breathing, where the source is located, and what you should do next to reduce the risk.

Risks to worker health should always be a top priority. If you believe that indoor air quality is causing harm to staff, the first step is to cease all operations which could put worker health in jeopardy.

The next step is to assess your air quality. This can be conducted over the course of a day or up to a few weeks with indoor air quality testing. This will tell you exactly what's in your air, what the concentrations are, and where the pollutants are coming from.

The recommended long-term solution is to install professional air quality monitors which measure and record your indoor air quality hour-by-hour and stream that data directly to a live dashboard — making it easier to spot issues before they become health risks. This is particularly important in high-risk businesses, like welding or plastics manufacturing.
