What?
- A needle stick injury occurs when a hypodermic needle or sharp object punctures the skin unexpectedly.
- Discarded needles and sharps are found on construction sites, especially during demolition and land clearance.
- Contaminated needles can transmit blood-borne viruses including Hepatitis B, Hepatitis C, and HIV.
- Wastewater treatment works, public realm projects, and brownfield sites carry the highest needle stick risk.
- COSHH 2002 classifies blood-borne viruses as biological hazards requiring assessment and control measures.
- The risk of Hepatitis B transmission from a single contaminated needle stick is approximately one in three.
- Needles may be hidden in overgrown vegetation, rubble, soil, inside walls, and under floorboards.
- Sharps bins must be available on site wherever needle finds are anticipated or have occurred previously.
- Post-exposure treatment must begin within one hour for maximum effectiveness against blood-borne infections.
- Hepatitis B vaccination is recommended for all construction workers likely to encounter sharps on site.
Why?
| Blood-borne infection | A single needle stick can transmit Hepatitis B with a 30% probability — this is a life-changing infection. |
| Hidden hazard | Discarded needles are invisible in rubble, soil, and vegetation until they puncture skin during manual work. |
| Time-critical treatment | Post-exposure prophylaxis must start within one hour — delays reduce effectiveness against HIV and Hepatitis B. |
| Legal duty | COSHH 2002 requires employers to assess biological risks and provide vaccination where workers are at risk. |
