Why construction workers are at risk

Construction combines several of the most serious occupational hazards in one workplace. OSHA identifies falls as a leading cause of death in construction, and long-term exposure to respirable crystalline silica from cutting concrete, brick and stone can cause silicosis, lung cancer and other diseases. Noise and vibration damage builds up slowly and is permanent.

Outdoor work adds ultraviolet exposure and heat illness. These are not risks to accept as part of the job; they are risks that can be controlled.

01Falls from height

Falls from ladders, scaffolds, roofs and openings cause serious injuries and deaths every year. OSHA's fall prevention campaign summarises the approach as plan, provide the right equipment, and train everyone to use it safely.

What helps

  • Do not work at height without edge protection, a safe platform or fall arrest that is set up and checked.
  • Use ladders only for short tasks, secured, on firm ground, with three points of contact.
  • Cover or guard floor openings and skylights.
  • Stop and report if equipment is missing or damaged.

02Silica dust and lung disease

Cutting, grinding and drilling concrete, stone, brick and tiles produces fine silica dust that can be breathed deep into the lungs. The NHS describes silicosis as a long-term lung disease caused by inhaling silica, which can keep worsening after exposure stops. It has no cure, which is why controlling dust matters.

What helps

  • Use tools with water suppression or on-tool extraction when cutting or grinding.
  • Wear correctly fitted respiratory protection (face-fit tested) where dust controls are not enough.
  • Never dry-sweep or use compressed air to clean silica dust.
  • Take part in health surveillance offered by your employer.

03Noise, vibration, sun and heat

Loud tools and machinery cause permanent hearing loss and tinnitus over time. Regular use of vibrating tools can cause hand-arm vibration syndrome, with tingling, numbness and white fingers. WHO warns that ultraviolet exposure causes skin cancer, and OSHA notes that heat illness can be fatal and that new workers are especially vulnerable.

What helps

  • Use quieter methods and tools, and wear hearing protection in noisy areas.
  • Limit time on vibrating tools, keep tools maintained and keep hands warm.
  • Cover up, wear a hat with a neck flap and use sunscreen; seek shade at midday.
  • Drink water often, take rest breaks in shade and build up gradually to working in heat.

Weekly checklist for construction workers

  • Check edge protection, ladders and harnesses before work at height.
  • Confirm dust controls are working before cutting or grinding.
  • Carry hearing protection and use it every time noise is high.
  • Cover skin and drink water regularly on hot or sunny days.
  • Record time on vibrating tools.
  • Check your skin for new or changing moles once a month.

When to see a professional

  • A cough, breathlessness or chest tightness that lasts for weeks.
  • Ringing in the ears or difficulty following conversation.
  • Tingling, numbness or white fingers, especially in the cold.
  • A new or changing mole or skin patch, or a sore that does not heal.

Heat stroke is an emergency: call for help if someone is confused, collapses, stops sweating or has a very high temperature, and cool them while you wait.

Where ONU fits

ONU brings your sleep, activity and recovery trends together, so you can see how long, hot or physically heavy weeks affect your sleep and recovery. It does not measure dust, noise or heat exposure and cannot detect lung or hearing damage. Use site health surveillance and your doctor for that.

Common questions

Is a dust mask enough for cutting concrete?

A simple paper mask is not adequate for silica dust. The priority is water suppression or extraction on the tool, with properly rated and face-fit-tested respiratory protection as an additional layer.

Can hearing damaged by noise recover?

Noise-induced hearing loss is permanent. Temporary dullness after a loud day is a warning sign that exposure is high enough to cause lasting damage.

What are the early signs of heat illness?

Heavy sweating, headache, dizziness, nausea, cramps and weakness can signal heat exhaustion. Move to shade, drink water and cool down. Confusion or collapse is an emergency.
