Construction workers regularly use and are exposed to hazardous substances including cement, solvents, adhesives, paints, and fuels. COSHH requires employers to assess the risks from these substances and put control measures in place. Skin contact, inhalation, and ingestion can all cause serious health effects ranging from dermatitis to occupational asthma and cancer. Understanding your exposure risks and the controls available protects your long-term health.
Key Hazards
Skin damage and occupational dermatitis from chemical contact
Respiratory illness from inhaling dust, fumes, and vapours
Poisoning through ingestion from poor hygiene after handling chemicals
Long-term health conditions including asthma and cancer from repeated exposure
Control Measures
Read the safety data sheet for every substance before you use it on site.
Ensure a COSHH assessment has been completed for each hazardous substance used in your task.
Use the least hazardous alternative product wherever one is available for the same job.
Wear the correct PPE specified in the COSHH assessment including gloves, goggles, and RPE.
Use local exhaust ventilation or work in well-ventilated areas when handling volatile substances.
Store all hazardous substances in designated, labelled, and bunded storage areas when not in use.
Wash your hands and exposed skin thoroughly before eating, drinking, or using the toilet.
Report any skin irritation, breathing difficulties, or other symptoms to your supervisor immediately.
Attend health surveillance appointments when required for your role and the substances you handle.
Remember
Every hazardous substance on site must have a COSHH assessment completed before use.
Always read the safety data sheet to understand the risks and required protective measures.
Skin disease is the most common occupational illness in UK construction workers today.
Poor hand hygiene allows chemical contamination to be ingested during breaks and mealtimes.
RPE only works if it fits properly, so ensure you have had a face-fit test.
Report any symptoms early because occupational diseases are much harder to treat once advanced.
