How to Prepare for a HSE Visit Related to Air Quality

Preparing for a visit from the Health and Safety Executive (HSE) can feel daunting - particularly when air quality is involved. The reassuring part is that most issues arise from missing paperwork, unclear procedures, or minor oversights, all of which can be addressed before an inspector arrives.

This guide explains how to prepare for a HSE air quality inspection in a clear, practical, and manageable way.

What Does the HSE Actually Check During an Air Quality Visit?

Many businesses assume the HSE focuses primarily on equipment, but that’s rarely the full picture. Inspectors are looking for evidence that you understand your risks and are managing them effectively.

Typical checks include:

• Whether airborne contaminants have been properly identified

• Whether exposure levels are being monitored

• Whether staff understand safe working practices

• Whether control measures are being maintained

• Whether documentation is complete and accessible

In addition to this, HSE inspectors, Occupational Health professionals, and ISO auditors will often expect to see air quality testing and examination reports produced to recognised standards, such as P601.

Understanding what the HSE checks for air quality compliance allows you to prepare confidently, avoid guesswork, and reduce the risk of issues during inspection.

Step 1: Make Sure Your COSHH Assessment Is Clear and Current

Your COSHH assessment is usually the first document an inspector will request. It should clearly outline:

• The substances used or generated

• The tasks that create exposure

• Who may be affected

• The control measures in place

• How those controls are monitored and reviewed

If your assessment is vague, outdated, or missing key information, update it ahead of the visit. This is a critical part of how to prepare for a HSE air quality inspection.

Step 2: Gather All Air Quality Documentation in One Place

Disorganised paperwork is one of the most common challenges businesses face during inspections.

Before the visit, ensure you have easy access to:

• COSHH assessments

• Air monitoring results

• Maintenance logs

• Training records

• Safe operating procedures

• LEV examination and test reports (e.g. P601 standard)

Having everything organised and readily available demonstrates that you understand HSE requirements for air quality documentation and take compliance seriously.

Carn Engineering carries out thorough examinations and produces reports in line with the P601 standard, ensuring your documentation meets the expectations of regulators and auditors.

Step 3: Check That Your Control Measures Are Working as Intended

Inspectors are not just looking for installed controls—they want proof that they are effective.

Review:

• Airflow checks

• Filter replacements

• Ductwork condition

• Any recent repairs

• Records from daily or weekly checks

  
  

If anything is overdue, incomplete, or unclear, address it before the inspection. Strong systems here directly support what the HSE checks for air quality compliance.

Step 4: Make Sure Staff Know What to Do (and Why)

HSE inspectors often speak directly with employees. They may ask:

• What hazards they work with

• How they minimise exposure

• How they use extraction or ventilation systems

• What actions they take if something goes wrong

  
  

A short refresher briefing before the visit can significantly improve confidence and consistency across your team - another key element in how to prepare for a HSE air quality inspection.

Step 5: Walk the Workspace Like an Inspector

Before the visit, carry out a quick visual check of your workspace from an inspector’s perspective.

Look for:

• Dust build-up on surfaces

• Blocked vents or poor airflow

• Blocked or clogged filters

• Overfilled dust collection pots

• Damaged ducting

• Damaged, missing, or unreadable gauges

• Incorrect use of equipment

• Missing signage

• PPE not being worn

These are the kinds of visible issues that often trigger deeper questions and are a key part of what the HSE checks for air quality compliance. Fixing them early can make a significant difference during an inspection.
