What is Health & Safety in Construction?

Health & Safety in construction refers to the protocols, procedures, and measures put in place to keep your sites safe for workers and visitors. This includes planning, communicating and scheduling work safely to reduce overall risk.

Legally, employers and managers have a duty to provide a safe environment for workers, as well as any third parties and members of the public. This is an obligation backed by strict laws designed to protect workers, and failing to stay compliant can lead to hefty fines, legal action, and even imprisonment.

Why is Health & Safety important in construction?

The construction industry is sadly no stranger to accidents, which can have serious consequences. According to the Health and Safety Executive (HSE), there were 35 fatal injuries in 2024/25, highlighting why getting your business’s approach to Health & Safety right is so critical.

Along with the obvious legal requirements, there are plenty of other reasons to have a solid policy:

• The human cost — Accidents and ill health on site can range from minor cuts to life-changing injuries or even death in extreme scenarios. The physical and mental toll on an injured worker and their colleagues can last a lifetime and have a significant impact on their happiness and wellbeing.
• Financial impact — Accidents, ill health, and HSE investigations all come with a cost. You could be looking at potential compensation payments, legal fees, and higher insurance premiums.
• Project delays — An incident can shut down a site for days or even weeks while an investigation takes place. This impacts your timelines, makes projects overrun, and eats into your profits.
• Reputation — In this industry, your reputation is everything. A poor safety record can put off potential clients and make it harder to recruit skilled workers.

Key Health & Safety legislation to be aware of

Understanding the legal requirements for Health & Safety on your construction site can be tricky, but there are a few key pieces of legislation you need to be familiar with. These are:

• The Health and Safety at Work etc. Act 1974 (HSWA)

This is the big one. It outlines the responsibilities employers have to protect the health, safety, and welfare of their employees. It essentially says you should do everything “reasonably practicable” to keep people safe.

• Construction (Design and Management) Regulations 2015 (CDM)

These regulations are specific to construction. They make sure Health & Safety are considered at every stage of a project, from the initial concept and design right through to completion.

If you need help understanding this framework, our CDM support services can guide you through the process.

• The Control of Substances Hazardous to Health Regulations 2002 (COSHH)

Construction sites are full of hazardous substances, from dust and fumes to chemicals and cleaning products. COSHH requires you to assess the risks these pose and put measures in place to control them.

• Workplace (Health, Safety and Welfare) Regulations 1992

These cover the basics of a safe working environment, like ventilation, lighting, and employee welfare facilities like access to a break room and working toilet.

Who is responsible for Health & Safety on a construction site?

Safety isn’t just one person’s job. Under the CDM Regulations, responsibility is shared across several key roles:

1. The client — The person or organisation you’re doing the work for. They should set up the project safely from the start and allocate proper resources.
2. Principal Designer — Responsible for planning, managing, and monitoring Health & Safety during the pre-construction phase. They work to remove risks in the design itself.
3. Principal Contractor — Holds overall responsibility for safety during the construction phase. They create the Construction Phase Plan, manage site risks, and make sure all workers are trained and supervised.
4. Subcontractors — Must stick to the Principal Contractor’s safety guidelines and make sure their own teams work safely.
5. Workers — Everyone on site has a duty to take care of their own Health & Safety, use equipment correctly, and report any hazards they spot.

By working together under this structure, everyone involved helps to create a safer environment where fewer accidents are likely to happen.

What are the common safety hazards on a construction site?

Construction sites are made up of lots of moving parts, and hazards can pop up where you least expect them. Here are the big ones to watch out for:

1. Falls from a height

It’s an unfortunate reality that falls are the leading cause of fatalities in the industry. In 2024/25, falls from height accounted for 53% of fatal injuries in the construction industry. Whether it’s from scaffolding, ladders, or fragile roofs, working at height comes with a high risk of injury without strict planning and protection.

2. Handling hazardous materials

On construction sites, it’s common to handle hazardous substances such as asbestos, lead, solvents, chemicals, and even mould during refurbishments. Without the right protection, these can cause serious long-term health issues, from skin burns to respiratory diseases.

3. Machinery and equipment

Heavy plant machinery, power tools, and moving vehicles are essential for the job, but they’re also dangerous. Some of the risks include being struck by moving objects, getting caught in machinery, or vehicle collisions.

Of the 35 construction-related deaths in the last year, 10% were the result of being struck by a moving object. If not properly managed, the risk of accidents due to being struck by moving parts or caught in machinery significantly increases. It’s the responsibility of those in charge of a site to design a traffic management system to make sure vehicles are operating as far away from pedestrians as possible. 

4. Dusty conditions

Dust might seem like a minor nuisance, but it’s a silent killer that can leave your workers with long-term health conditions. There are several types of dust that can cause problems on a construction site, including:

• Silica dust — Created when working with concrete, brick, or stone. Cutting, grinding, drilling, or blasting these materials generates fine silica particles, and long-term exposure to breathing these particles can lead to serious health conditions like silicosis, lung cancer, and other respiratory diseases.
• Wood dust — Produced when working with saws, sanders, or routers, this can cause issues like eye and nose irritation, asthma, and other throat conditions.
• Lead dust — Activities involving lead-based paint, demolition, or renovation of older structures can all kick up lead dust. Exposure can cause severe health issues, especially affecting the nervous system, kidneys, and reproductive system.
• Cement dust — Cement dust is produced during activities like mixing, cutting, or grinding cement-based materials. Inhaling this dust can cause respiratory problems, including bronchitis, asthma, or a condition called cement pneumoconiosis.

Silica, wood, and cement dust are all covered by COSHH regulations, which require construction sites to provide PPE and suitable ventilation to reduce contact with dust particles.

Because it poses such a serious threat, lead dust falls under its own legislation, The Control of Lead at Work Regulations 2002. This requires employers to assess the risk of lead exposure, introduce measures to reduce exposure, provide PPE, keep up good hygiene standards on site, and keep an eye on the health of any workers who may be exposed to lead dust.

5. Electrical hazards

Contact with live wires — either overhead power lines or underground cables — is a major risk. Even lower voltage equipment can cause serious injury if it’s damaged or misused. 

In fact, according to the HSE, 7% of all construction-related deaths are the result of contact with a power source, so it’s vital to keep any electrical hazards under control. This includes regular inspections and maintenance of electrical tools, lock out and tag out procedures, and hiring competent electrical contractors.

6. Noise and vibration

Construction sites are loud, and long-term exposure to high noise levels can cause permanent hearing loss. Monitoring noise levels and implementing hearing protection zones, training, and proper instruction are crucial to preventing occupational hearing loss. 

Similarly, Hand Arm Vibration Syndrome, White Finger and Dermatitis all potential risks when operating vibrating power tools. Preventing these risks requires monitoring vibration exposure on site and providing health surveillance to those likely to be exposed.

How to carry out a construction health and safety inspection

To identify any potential hazards on site, you’ll need to carry out a health and safety inspection. This is more than just a glance around the site; it’s a way to check that your safety regulations are actually being followed and to spot risks before they cause harm.

You might choose to focus on specific, high-risk areas, like your work-at-height policy, or take a broader approach that analyses every corner of your site. Crucially, the inspection also involves watching your team in action to make sure they’re following the latest regulations, rather than just checking that the equipment is safe.

While you can handle this internally, it has to be carried out by a competent person. It can be helpful to bring in someone independent — like a third-party health and safety expert — to give you an unbiased, objective view of how your business’s policies are shaping up.

Here’s a simple process to follow:

1. Visit the site and assess risks

Start by walking the site perimeter to make sure security is maintained. Verify that access points are controlled and that no unauthorised personnel are on site. Once security is confirmed, move on to check the induction process to ensure all workers, contractors, and visitors are briefed on the site’s health and safety protocols.

Then, assess the following key areas:

• Vehicle and pedestrian segregation — Make sure vehicles and workers are clearly separated, using barriers or designated walkways.
• Contractors and subcontractors — Confirm that all external teams are complying with site rules and safety measures. Check their induction records so you know they’re aware of site hazards.
• Welfare facilities — Inspect the condition of welfare facilities (e.g. toilets, canteens, first aid stations) to make sure they meet legal requirements and are in good condition.
• Adherence to site rules — Ensure all workers are following the site’s health and safety procedures, including wearing PPE and using equipment correctly.

2. Make a note of on-site observations

Don’t just rely on your memory. Use a checklist or a tablet to record your observations immediately, and be specific. Instead of writing down “messy area”, give more detail, e.g. “trip hazard: loose bricks on walkway B”. This makes it easier to target specific issues when implementing fixes.

3. Identify strengths and weaknesses

It’s not just about finding faults. If you see something that’s working well, make a note of it. It’s important to identify what’s effective so you can replicate it elsewhere on site.

4. Rank issue severity

You can’t fix everything at once, so prioritise the risks that could cause the most harm. For example, a missing guardrail on a fourth-floor scaffold needs to be fixed immediately, whereas a flickering light in the canteen can wait until tomorrow.

5. Implement a performance review system

Inspections shouldn’t be one-offs. Set up a regular schedule (e.g., weekly or monthly) and use Key Performance Indicators (KPIs) alongside incident rates and occasional audits to track whether your site is getting safer over time.

6. Compile the inspection report

Put together a comprehensive inspection report that covers all of your findings, observations, and recommendations for improvement. The report should be clear, concise, and easily accessible to anyone within your business who needs it.

You might want to think about using health and safety software to manage and store any inspection reports, keeping a clear audit trail for future reference.

7. Take steps to remove hazards

This is the most important part of the process.

Create an action plan to fix any issues you found during the inspection, assign tasks to specific people, and set realistic deadlines. This might involve putting in corrective measures, providing additional staff training, updating safety procedures, improving health and safety policies, or investing in newer, safer equipment.

Prioritise actions based on the level of risk, taking care of anything that poses a danger to life immediately.

Practical tips for controlling hazards on a construction site

Knowing the risks is half the battle; the other half is controlling them. Here are some practical tips to keep your site safe:

1. Falls from a height

Working at height comes with the risk of falls, but the chances of this happening can be reduced with the right precautions:

• Plan ahead — Can you avoid working at height? If not, use the right equipment.
• Use protection — Install guardrails and toe boards on all scaffolding.
• Harness up — Provide personal fall arrest systems (and training on how to use them) where guardrails aren’t possible.
• Inspect ladders — Check them every time before use. They should only be used for short, low-risk tasks. For any tasks requiring ladders over 9 metres, you’ll need to provide safe landing areas or rest platforms where reasonably practicable. 

2. Handling hazardous materials

Hazardous materials are common on construction sites, but you can greatly reduce the risks associated with them if you apply the right control measures. Employers have a duty to make sure that hazardous substances are used safely and that the least hazardous option is chosen wherever practicable.

To handle hazardous materials safely, here are the control measures you should apply, prioritised according to the Hierarchy of Controls:

• 1. Eliminate the hazard — Where possible, replace harmful substances with safer alternatives. If a chemical isn’t essential, consider using a less hazardous product or eliminating its use altogether.
• 2. Substitute with a safer form — If the hazardous substance must be used, switch to a safer form of it. For example, use a paste instead of a powder to reduce airborne dust.
• 3. Modify the process — If possible, adjust the process to reduce the emission of hazardous substances. For instance, wetting materials or using closed systems during handling can minimise exposure.
• 4. Enclose the process — Use enclosures or barriers to prevent the escape of hazardous substances into the environment. For example, dust collection systems can be used during cutting or sanding.
• 5. Extract emissions at source — Install local exhaust ventilation to capture and remove hazardous substances from the air near their source, such as fume extraction units in welding or cutting areas.
• 6. Limit exposure to workers — Only allow essential workers to be exposed to hazardous materials. Reduce the number of people in areas where exposure is likely, and provide training on safety protocols.
• 7. Use PPE — Personal protective equipment, like gloves, coveralls, and respirators, should be used where other controls cannot completely eliminate the hazard. Make sure PPE fits properly and is suitable for the task.

3. Machinery and equipment

Working with heavy machinery is one of the biggest risks on any site, but it can be done safely, provided that the following precautions are taken:

• Training is key — Only trained and competent people should operate plant machinery.
• Segregate traffic — Keep vehicles and pedestrians separate with barriers and designated walkways. Check out our guide on workplace transport safety for more tips on this.
• Maintenance — Rigorous checks are vital. If it’s broken, tag it and take it out of use.

4. Dusty conditions

Dust is a real concern on building sites, but there are plenty of safe ways to handle it properly:

• Avoid dust creation — Opt for pre-cut materials wherever possible, and use a local exhaust and on-tool extraction to prevent dust getting in the air.
• Damp it down — Use water suppression systems to mist the air and stop dust from floating across your site.
• Vacuum it up — Use on-tool extraction systems to suck up dust particles rather than sweeping, which just kicks it back up into the air.
• Mask up — Provide suitable respirator masks for tasks where dust can’t be fully controlled.

5. Electrical hazards

The last thing you or anyone else on your site wants is an electric shock. Electrical hazards can be serious, even at lower voltages, so controlling the risk starts with preventing exposure wherever possible.

Here are some sensible ways to minimise electrical risks on site:

• Eliminate live working where possible — Carry out work on dead (non-energised) circuits wherever practicable. Use lock out and tag out procedures to make sure equipment can’t be accidentally re-energised while work is taking place.
• Use safer power sources — Use 110V electrical equipment on site where required and opt for battery-powered or cordless tools to reduce the risk of electric shock and cable damage.
• Inspect equipment regularly — Carry out visual checks on plugs, leads, and tools before use. Any damaged equipment should be reported immediately, taken out of service, and clearly labelled.
• Manage the environment — Avoid using electrical equipment in wet conditions unless it is specifically designed for that environment. Make sure cables are routed and protected properly to prevent damage, trips, or exposure to water.
• Control and manage cables — Keep cables tidy, secured, and away from walkways, sharp edges, and moving vehicles to reduce wear and accidental damage.
• Use PPE as a last resort — Where risks can’t be fully eliminated, provide suitable PPE, such as insulated gloves, alongside appropriate training and supervision.
