When it comes to working in construction, safety should always be at the forefront of everyone’s mind.

It doesn’t matter what task you’re doing – from working at height to handling heavy machinery, to something as mundane as filling out paperwork – every project brings its own challenges and risks. But while we often focus on the obvious hazards, there’s one that’s a bit more hidden, yet just as dangerous. And that’s respiratory risks.

Dust, fumes, gases, and vapours are a common part of many construction tasks. According to the Health & Safety Executive (HSE), 12,000 deaths from lung disease each year are estimated to be linked to past exposures at work. Left unmanaged, these invisible hazards can cause serious long-term health problems down the line.

In this blog, we’ll break down what respiratory risks in construction are, why they matter, and the practical steps you can take to keep your workforce safe.

What are the respiratory risks in construction?

When we talk about respiratory risks in construction, we’re referring to any hazards that can damage the lungs, airways, or the ability to breathe. The biggest culprits are:

  • Dust: From cutting, grinding, or drilling materials like concrete, wood, plasterboard, and bricks.
  • Fumes: Produced by welding, soldering, or using certain chemicals.
  • Gases and vapours: Released from paints, solvents, adhesives, and some machinery exhausts.

The particles don’t just disappear: they linger in the air long after the work’s finished. Breathe them in, and they can cause a range of health issues, from short-term irritation to long-term, life-threatening diseases like chronic obstructive pulmonary disease (COPD), occupational asthma, silicosis, and even lung cancer.

According to the HSE, in the UK, there are currently 20,000 new cases each year of work-related breathing or lung problems (averaged over the last three years).

Why is managing respiratory risks so important?

It’s easy to think of safety in construction as primarily about preventing accidents like falls, cuts, and collisions. But health risks can be just as severe, even if they’re slower to appear.

Respiratory diseases often develop over time, sometimes after decades of exposure. By the time symptoms show, the damage may already be done. That’s why prevention is so critical.

There’s also a legal angle. Under the Control of Substances Hazardous to Health (COSHH) Regulations 2002, employers have a legal duty to assess and control exposure to substances that can cause ill health. Failure to do so can result in hefty fines, legal action, and reputational damage.

But even moreso, it’s about creating a culture of care.

We say it a lot, but it’s true: your people are your greatest asset. Keeping them healthy doesn’t just help you stay on the right side of the law. It boosts morale, reduces absenteeism, and helps you build a reputation as a responsible, trustworthy business.

So, how can you tackle respiratory risks in construction head-on? Let’s take a look.

1. Identify the risks

First things first: you can’t manage what you don’t know. A thorough risk assessment is your starting point.

Look at the tasks your team carries out daily:

  • Are they cutting materials that create dust?
  • Are they welding, painting, or using solvents?
  • What equipment is in use?
  • Are there emissions or exhausts to consider?

Don’t just focus on the obvious. Think about the entire work environment, too:

  • Is there good ventilation?
  • Are tasks happening in confined spaces?
  • Are there nearby activities that could create airborne risks for others on site?

Be methodical. Involve your team. And remember, the more detailed your risk assessment, the better placed you’ll be to implement effective controls.

2. Use the hierarchy of controls

Once you’ve identified the risks, it’s time to tackle them. The hierarchy of controls is a simple but powerful tool for managing risks, with a clear order of priority:

  1. Eliminate the risk entirely. For example, can you use prefabricated materials to avoid cutting on-site? Eliminating hazards is the most effective control because it stops the risk at its source before it can cause harm.
  2. Substitute hazardous materials for less harmful alternatives. Could you swap solvent-based paints for water-based ones? Substitution helps to lower risks, even if it doesn’t cut them out completely.
  3. Engineer controls to reduce exposure. This might involve using local exhaust ventilation (LEV) systems, on-tool dust extraction, or setting up a barrier around activities that kick up dust. Engineering controls reduce the likelihood and level of exposure.
  4. Implement administrative controls. This includes setting up safe systems of work, training, clear signage, and job rotation to limit any one person’s exposure time. Administrative controls rely on human behaviour, making them less reliable than physical controls, but still important for risk management.
  5. Provide personal protective equipment (PPE). PPE, such as respiratory protective equipment (RPE), is the last line of defence. It doesn’t eliminate the hazard, but helps protect the individual when other controls can’t fully remove the risk.

Many sites jump straight to masks and respirators, but relying on PPE alone isn’t enough. After all, a face mask can only do so much!

3. Invest in the right equipment

When it comes to controlling respiratory risks in construction, the right equipment makes all the difference. Here are a couple of items you can use to make the job safer and easier:

  • Dust extraction tools: Use power tools with integrated dust extraction systems. This captures dust at the source, before it can spread into the air.
  • Vacuum systems: For clean-up, use industrial vacuum cleaners (with a HEPA filter) rather than sweeping, which can kick dust back into the air.
  • LEV systems: In workshops or enclosed areas, local exhaust ventilation systems can surround a work environment and suck up dust, filtering it out.
  • High-efficiency masks and respirators: Where RPE is needed, make sure it’s appropriate for the hazard (e.g., FFP3 masks for silica dust) and that it fits properly. Face-fit testing is a must!

Equipment is only effective if it’s well-maintained. Make sure to take part in regular inspections, servicing, and filter replacements to keep your employees safe.

4. Train your team

Knowledge is power, and when it comes to respiratory risks, it can be life-saving.

Your team needs to understand:

  • What the risks are and why they matter.
  • How to use equipment and controls properly.
  • How to maintain and care for their PPE.
  • How to spot signs of exposure or ill health.

Training should be part of your induction process for new starters and refreshed regularly for all staff. This is where Health & Safety Awareness training can make a real difference. It helps your team understand not just the risks they face, but how to work safely, confidently, and in line with best practices.

5. Monitor, review, and adapt

Managing respiratory risks in construction isn’t a one-and-done exercise. It’s an ongoing process.

Regular site inspections and air monitoring (where needed) can help you spot problems early, make adjustments, and make sure your controls remain effective.

Keep communication open. Encourage workers to report any issues, near misses, or concerns. Remember, your team’s on the front line – they’re the ones who will see if anything’s wrong first, so their feedback is invaluable.

6. Foster a culture of safety

Finally, creating a culture where safety is everyone’s business makes all the difference. Real change happens when:

  • Workers feel empowered to speak up
  • Workers see leadership taking respiratory risks seriously
  • Safe working practices are the norm

It’s not just about rules and regulations. By showing that you care about your team’s health, not just today, but for years to come, you build trust, loyalty, and a stronger business.

This is where SSIP certification can really help demonstrate your commitment. It’s a recognised standard that shows you’re serious about Health & Safety. If you’re tendering for contracts or working with larger clients, having that certification can give you a real competitive edge. It also helps with:

  • Streamlined pre-qualification processes, reducing paperwork and duplication
  • Increased trust and credibility with clients and contractors
  • Access to a wider range of contract opportunities
  • Evidence of compliance with legal and industry Health & Safety requirements
  • Improved workplace safety culture through adherence to best practices
