Construction is one of the industries that keeps the country moving. Roads are built, homes are repaired, factories are expanded and new workplaces appear across our towns and cities. Yet behind the finished buildings is a workforce that can spend decades exposed to dust, noise, vibration and chemicals.
The direct health risks
Construction workers can encounter a wide range of hazards depending on their trade and working environment. A bricklayer, welder, groundworker and plant operator will not necessarily face the same exposures, but there are common risks across the industry.
Cancer, silicosis and lung disease
Respirable crystalline silica is found in materials such as concrete, mortar, bricks and stone. When these materials are cut or drilled, very small particles can enter the lungs. Repeated or high exposure can cause serious respiratory disease, including silicosis and chronic obstructive pulmonary disease.
Construction workers can also be exposed to substances that are known or suspected to cause cancer. The risk depends on the material and level of exposure, but asbestos remains one of the most dangerous. Some older buildings contain asbestos, meaning workers involved in refurbishment and demolition may encounter it unexpectedly if the appropriate checks have not been carried out.
Skin problems
Construction workers regularly come into contact with cement, oils, solvents, resins and other substances that can irritate the skin. These materials can cause dermatitis and, in some circumstances, serious chemical burns. Repeated exposure can gradually damage the skin’s natural protective barrier. Once that barrier has been compromised, everyday substances can cause further irritation.
Noise induced hearing loss
Construction sites can be extremely noisy. Power tools, compressors, generators, drilling equipment and heavy machinery can produce levels of noise capable of damaging hearing. Noise induced hearing loss tends to happen gradually. There may be no obvious warning that damage is happening until a worker starts struggling to follow conversations or notices persistent ringing in their ears.
Hand Arm Vibration Syndrome
Regular use of vibrating tools such as breakers, grinders and power drills can expose workers to hand arm vibration. Over time, this can contribute to Hand Arm Vibration Syndrome, commonly known as HAVS. Symptoms can include tingling, numbness, reduced grip strength and problems with circulation in the fingers. Cold conditions can make symptoms worse.
Whole body vibration
Vibration doesn’t just affect the hands. Plant operators can experience whole body vibration when regularly operating vehicles and machinery, particularly over uneven surfaces. Long term exposure can contribute to back pain and musculoskeletal problems. Seat condition, vehicle maintenance, working surfaces and driving time can all influence exposure, so managing the risk requires more than simply telling workers to sit correctly.
The indirect health risks
Not every workplace health problem comes directly from a hazardous substance or piece of machinery. Construction can impact health through working patterns and lifestyle. Long shifts and physically demanding work can make it difficult to maintain regular sleep, exercise and healthy eating habits. Early starts might encourage workers to rely on convenience food and caffeine, while fatigue could become normalised as part of the job.
Mental health is another consideration. Construction workers may experience stress caused by workload, financial pressure, job insecurity, long periods away from home or concerns about performance and deadlines. There could also be a reluctance to talk openly about mental health in an industry where people may feel pressure to appear resilient.
Physical and mental health are not separate issues. Poor sleep can affect concentration and mood, while stress can make it harder to maintain healthy habits. Improving occupational health therefore means looking at the worker as a whole rather than focusing solely on individual hazards.
What can workers do to improve their health?
Workers cannot control every aspect of a construction site, but there are some practical steps they can take to control their health. The first is to take workplace hazards seriously, particularly when they do not produce immediate symptoms.
Use the control measures and protective equipment provided, follow site procedures and report damaged equipment or unsafe conditions. If a worker is regularly exposed to dust, noise or vibration, they should understand what controls are in place and why they matter.
Away from the site, getting enough sleep, eating a balanced diet, staying physically active and moderating alcohol consumption can make a considerable difference. Most importantly, workers should feel able to speak to someone when their physical or mental health is deteriorating.
What should employers do?
Employers have a responsibility to manage risks rather than relying on workers to protect themselves. This begins with proper a risk assessment and identifying potential hazardous exposure.
Personal protective equipment has an important role, but it should not be the only control measure. Where possible, employers should eliminate or reduce hazards at source. Where exposure cannot be adequately controlled, health surveillance can provide an additional layer of protection.
Health surveillance can identify early signs of occupational illness or injury and provide useful information about whether existing controls are working. Just as importantly, employers need to create a workplace where workers can raise concerns about their health without feeling that doing so makes them appear weak or unreliable.
Looking after long term health
Construction will always involve some degree of physical risk. The aim is not to pretend otherwise, but to understand those risks and manage them properly. Good construction health is ultimately about making sure that people can do their jobs safely today without paying the price for them tomorrow. For an industry that builds the places in which the rest of us live and work, that is a responsibility worth taking seriously.
