When an accident, injury, ill-health case or dangerous occurrence happens on site, you must know how to respond, who to tell and how it is recorded. Getting this right protects lives and is a legal requirement; getting it wrong can cost someone their life.
RIDDOR 2013 (the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations) places a duty to report serious work-related incidents to the enforcing authority (the HSE). The responsible person reports the most serious events; not every cut or bruise is RIDDOR-reportable, but the following are:
The site accident book records all injuries, however minor, plus near misses. Near misses are warnings: recording them lets the cause be fixed before someone is hurt. Always report hazards, near misses and accidents up the line to your supervisor.
Emergency and evacuation procedures: on arrival, learn the alarm sound, the escape routes, and the assembly point. If you discover an incident, raise the alarm first, then ensure the emergency services are called (999/112), giving the precise site address and access. Do not put yourself at risk.
The first aider gives immediate, limited help to preserve life, prevent worsening and promote recovery — they are not a doctor and stay within their training. The first-aid kit holds dressings, bandages, plasters, wipes and gloves, but no medication. Basic responses to know:
Under-reporting is dangerous and unacceptable: hiding accidents hides the hazard, denies the casualty proper care and breaches the law, so the same accident can happen again — with a worse outcome.

18. What is the main role of an appointed first aider on a construction site?
A first aider is trained to give immediate, basic help to a casualty and, where necessary, to summon further medical assistance, not to act as a doctor. Source: Health and Safety (First-Aid) Regulations 1981
19. A workmate collapses and you are not a trained first aider. What is the best action?

22. How should you be able to find out who the first aiders are on your site?
Employers must inform workers of first-aid arrangements, typically through induction and notices showing who the first aiders are and where to find first-aid facilities. Source: Health and Safety (First-Aid) Regulations 1981
23. An operative complains of crushing chest pain and looks unwell. The first aider suspects a heart attack. What is the most appropriate response?
