Breathing Air Quality Testing for Air Compressors

Is your compressed air system providing clean, safe breathing air for workers?

The air flowing through your compressors could contain dangerous contaminants which may be present in a workplace atmosphere, putting your team at risk.

Control Gear's Breathing Air Quality Testing for Air Compressors

Regular breathing air testing is not just a regulatory requirement – it is essential for protecting lives, preventing equipment damage, and avoiding costly penalties.

Control Gear delivers fast, accurate, quality-assured breathing air quality testing for air compressors.

Why Breathing Air Testing Matters

Breathing Air Quality Testing for Air Compressors
  • Worker Safety: contaminated breathing air can cause immediate health problems and long-term diseases. Regulations state that air for breathing shall not contain contaminants at concentrations that exceed exposure limits for a defined list of pollutants.
  • Legal Requirements: UK regulations (BS EN12021:2014) mandate regular air testing to ensure compliance. COSHH (Control of Substances Hazardous to Health) regulations identify the maximum exposure limits for harmful substances. Contaminants must be kept to as low a level as possible.
  • Business Protection: proper testing ensures the quality of compressed air, prevents equipment damage, reduces downtime, and avoids penalties.
  • Cost Efficiency: regular compressed air quality testing is more affordable than dealing with health incidents or equipment failure.
  • Peace of Mind: knowing your compressed breathing air meets safety standards provides confidence for both employers and employees.

The Hidden Dangers in Compressed Air Systems

Many people do not realise that compressed gas for breathing is not automatically safe. Your system might be pushing out invisible contaminants, which may cause toxic or harmful effects, harming or even killing workers. Regulations require UK employers to conduct breathing air quality tests to ensure a safe working environment. 

According to the British Safety Council, respiratory protective equipment-related incidents cause approximately 15 workplace fatalities each year in the UK, with many more suffering serious health complications from contaminated air exposure.

Risk Assessment of Common Contaminants That Threaten Worker Safety

Contaminant Source Health Risk Maximum Allowed
(BS EN12021:2014)
Carbon Monoxide (CO) Engine exhaust, combustion Poisoning, death 5 ppm
Oil Mist/Vapour Compressor lubrication Lung disease, respiratory issues 0.5 mg/m³
Water Vapour Ambient air, condensation Bacterial growth, freezing Pressure-dependent (typically <25 mg/m³)
Carbon Dioxide (CO₂) Ambient air, combustion Dizziness, headaches 500 ppm
Particulate Matter Dust, rust, pipe debris Lung irritation, system clogs Various classes based on particle size
Oxygen (O₂) Imbalance System issues Suffocation or fire risk 21% ±1% (volume)

Why Regular Breathing Air Quality Testing Is Non-Negotiable

Health and Safety Comes First

Workers using respiratory protective equipment connected to compressed air systems put their lives in your hands. Research published in the Journal of Occupational Health shows that even brief exposure to contaminated air can cause:

  • Immediate symptoms: headaches, dizziness, nausea.
  • Short-term health issues: respiratory irritation, decreased cognitive function.
  • Long-term concerns: chronic lung disease, neurological damage.

Regulations stipulate that breathing air shall have a dew point sufficiently low to prevent condensation and freezing, and contaminants shall be kept within specified levels to ensure a safe working environment.

Legal Requirements You Cannot Ignore

In the UK, compressed breathing air must comply with strict standards:

  • BS EN12021:2014: sets specific limits for contaminants in compressed breathing air.
  • HSE Guidelines: require regular testing and documentation.
  • ISO 8573: classifies air purity levels for different applications.

Failing to meet these standards can result in:

  • Fines up to £20,000 per violation.
  • Potential criminal charges for negligence.
  • Site shutdowns until compliance is achieved.
  • Increased insurance premiums.

Protecting Your Equipment Investment

Poor air quality does not just harm people – it damages your equipment, too. A study by the British Compressed Air Society found that:

  • Systems with properly tested air quality last 30–40% longer.
  • Maintenance costs decrease by up to 25% with regular testing.
  • Filter replacement frequency drops significantly when air quality is monitored.

Industries That Need Regular Compressed Air Testing

Several sectors rely on absolutely pure gas for breathing:

  • Healthcare: for medical air systems and patient care
  • Diving: for underwater breathing apparatus
  • Fire and Rescue: for emergency response teams
  • Chemical Manufacturing: for work in hazardous environments
  • Pharmaceutical Production: for clean room operations
  • Oil and Gas: for confined space entry work

How Often Should You Test Your Breathing Air?

The frequency depends on your specific industry and usage, but generally:

  • Every three months: minimum standard for most applications
  • Monthly testing: recommended for high-risk environments
  • After maintenance: any time the system is opened or modified
  • When location changes: if compressors are moved to new environments

According to data from the British Compressed Air Society (BCAS), facilities that implement air testing at least every three months reduce workplace air-related incidents by 87% compared to those testing annually.

The Testing Process: What to Expect

Our comprehensive breathing air testing follows a proven four-step process:

1. Site Assessment

  • Evaluate your entire compressed air system
  • Identify potential contamination sources
  • Map testing points for comprehensive coverage

2. Sample Collection and Testing

  • Use specialised equipment to capture air samples
  • Analyse for all regulated contaminants
  • Compare results against current standards

3. Compliance Reporting

  • Provide detailed documentation of all findings
  • Indicate pass/fail status for each contaminant
  • Document certification for regulatory compliance

4. Recommendations and Support

  • Suggest specific improvements if needed
  • Implement regular testing schedules
  • Offer monitoring solutions for continuous protection

Cost vs Benefit: Why Testing Makes Financial Sense

Some businesses hesitate to invest in regular air testing, but consider the cost comparisons below.

Average cost of quarterly testing
£800–£1,200 per year
Average cost
Workplace illness claim
£18,000+
Equipment replacement due to contamination
£6,000–£15,000
Regulatory fines
£5,000–£20,000 per violation

 

As these figures from the HSE and insurance industry data show, prevention is dramatically more cost-effective than dealing with the consequences of poor air quality.

Warning Signs That Breathing Air May Need Testing

Do not wait for scheduled testing if you notice:

  • Workers reporting unusual odours in the air supply
  • Increased moisture in the system
  • Unexpected filter discoloration
  • Unusual compressor noise or performance
  • Oil spots anywhere in the system
  • Worker complaints of headaches or respiratory issues
