Construction Site Accidents Prosecutions
1. Overview: Construction Site Accidents and Legal Context
Construction sites are high-risk environments. Accidents can lead to serious injuries or fatalities. Prosecutions arise when accidents occur due to negligence, breaches of health and safety regulations, or failure to follow proper procedures.
Legal Framework:
Health and Safety at Work etc. Act 1974 (HSWA 1974) – primary legislation for workplace safety.
Management of Health and Safety at Work Regulations 1999 – requires risk assessments and safe systems of work.
Construction (Design and Management) Regulations 2015 (CDM 2015) – specific duties for construction projects.
Workplace (Health, Safety and Welfare) Regulations 1992
Offences can be criminal, with fines or imprisonment, and may also lead to civil claims.
