Accident and Near-Miss Reporting Procedures for Site Security Officers

A practical guide to responding to and reporting accidents and near misses on UK sites, with a report checklist, RIDDOR explained and near-miss examples.
This article is general guidance and is not legal advice. Always follow your employer’s policy and your site’s assignment instructions.
On construction sites, warehouses, logistics hubs and industrial premises, security officers are often the first people to see something go wrong. You might be the only person on site at night, the one watching the gate when a vehicle clips a pedestrian, or the officer on patrol who notices a scaffold board hanging loose.
What you do in the next few minutes, and what you write down afterwards, can save lives, prevent repeat incidents and protect your employer. This guide explains how to respond to and report accidents and near misses clearly and correctly.
RIDDOR applies in England, Scotland and Wales. Northern Ireland has its own version, so check local guidance if you work there.
Key Takeaways
- Make the scene safe and get help before you think about paperwork.
- Near misses are free lessons, so report every one.
- A good report is factual, timed and written while details are fresh.
- RIDDOR requires certain injuries, diseases and dangerous occurrences to be reported to the HSE.
- Security officers support RIDDOR reporting, but the responsible person usually submits it.

Accidents, near misses and dangerous occurrences explained
These terms are often mixed up, so it helps to be clear:
| Term | Meaning | Example |
|---|---|---|
| Accident | An unplanned event that causes injury, ill health or damage | A worker slips on a wet ramp and breaks a wrist |
| Near miss | An event that could have caused harm but did not | A reversing lorry stops a metre from a pedestrian |
| Dangerous occurrence | A specific serious event listed in RIDDOR, whether or not anyone is hurt | A scaffold collapse or a crane overturning |
| Unsafe condition | A hazard that has not yet caused an event | A missing edge barrier or a broken light in a stairwell |
Safety professionals often talk about the “accident pyramid”: for every serious injury, there are many minor ones and many more near misses. Tackling the near misses at the bottom of the pyramid is how you prevent the serious incidents at the top.
Your immediate actions at an accident scene
1. Check for danger
Do not become a second casualty. Look for moving vehicles, falling objects, live electricity, fire, gas or chemicals before you approach.
2. Get help
Call 999 for serious injuries, and alert site first aiders and the site manager by radio. If you are the only person on site, follow your lone worker procedure and tell your control room.
3. Give first aid if trained
Use your first aid training and the site’s first aid kit and defibrillator. Stay with the casualty until help arrives.
4. Control the area
Stop vehicles, set up a cordon, and keep people away. Guide the ambulance to the right gate and meet the crew.
5. Preserve evidence
Leave tools, equipment and materials where they are unless moving them is necessary for safety. Take photographs if site policy allows. Secure CCTV and vehicle camera footage before it is overwritten.
6. Identify witnesses
Take names, employers and contact numbers. Ask witnesses to write down what they saw as soon as possible, in their own words.
Responding to a near miss
Near misses do not need an ambulance, but they still need action:
- Stop the activity if the hazard is still present.
- Make the area safe, for example with cones or barriers.
- Tell the site supervisor straight away.
- Record the near miss on the site’s reporting system before the end of your shift.
Near-miss examples security officers commonly see
- Pedestrians walking through vehicle-only routes at the gate.
- Materials falling from height into an exclusion zone.
- Plant reversing without a banksman or traffic marshal.
- Blocked fire exits or propped-open fire doors.
- Damaged fencing that lets the public onto site.
- Unsecured gas cylinders or fuel stores.
- Trip hazards from cables across walkways.
Licence expiring? You need refresher training first
Door supervisors and security guards must complete SIA refresher training before they renew. One and two-day courses run across London and in Birmingham, Liverpool and Manchester, from £200.
Centres include Stratford, Aldgate and Bethnal Green.
How to write an accident or near-miss report
Your report may be read by site managers, insurers, the Health and Safety Executive (HSE), solicitors or a coroner. It needs to be accurate, clear and complete. Remember that you report twice. The site manager needs your report for the site’s records and any RIDDOR submission. Your own employer, the security company, also needs a copy for its incident log and insurers. Send both before the end of your shift, and keep a note of who received them.
Report checklist
- When: date and exact time of the event, and when you were informed.
- Where: precise location, such as “Gate 2, pedestrian crossing”.
- Who: names, roles and employers of people involved and witnesses.
- What happened: events in order, in plain language.
- Injuries: what they were, and what first aid or treatment was given.
- Equipment and vehicles: type, registration or plant number.
- Conditions: weather, lighting, ground surface and noise.
- Actions taken: who was called, cordons set, activity stopped.
- Evidence: photo references, CCTV camera numbers and times.
Writing tips
- Write in the first person: “I saw”, “I heard”.
- Record facts, not guesses about blame.
- Quote what people said where it matters.
- Use the 24-hour clock.
- Do not change your notes later. If you need to add something, add a dated, signed note.
RIDDOR explained for security officers
The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013, known as RIDDOR, require the “responsible person” to report certain incidents to the HSE. The responsible person is usually the employer, the site manager, or the person in control of the premises. The HSE’s RIDDOR pages give full details and the online reporting forms.
Reportable incidents include:
- Deaths of workers or non-workers arising from a work-related accident.
- Specified injuries to workers, such as most fractures (other than fingers, thumbs and toes), amputations, serious burns, loss of consciousness from a head injury or asphyxia, and certain crush injuries.
- Over-seven-day injuries, where a worker cannot do their normal work for more than seven consecutive days, not counting the day of the accident.
- Injuries to members of the public who are taken directly from the scene to hospital for treatment.
- Certain occupational diseases, such as occupational dermatitis or hand-arm vibration syndrome.
- Dangerous occurrences, such as the collapse of scaffolding or the failure of lifting equipment.
As a guide, deaths and specified injuries must be reported without delay, and over-seven-day injuries within 15 days of the accident. Injuries that keep a worker off normal duties for more than three days must be recorded, even though they do not need to be reported.
Security officers do not normally submit RIDDOR reports themselves, but your notes are often the main source of information. Tell your supervisor immediately about any serious injury or dangerous occurrence so the deadline is not missed.
The accident book
Employers with ten or more employees must keep an accident book, and many smaller employers keep one as good practice. Entries contain personal information, so they must be stored securely in line with UK GDPR. Tear-out record pages, rather than open books where everyone can read previous entries, help protect privacy.
Building a positive reporting culture
People often fail to report near misses because they worry about getting themselves or a colleague into trouble, or because reporting seems like a waste of time. Security teams can help change that:
- Thank people who report hazards.
- Make reporting quick, for example with a QR code or short form at the gate.
- Share what changed as a result of reports.
- Keep reports focused on learning, not blame.
- Include near-miss trends in your shift handover.
Using near-miss data to prevent accidents
When near-miss reports are reviewed together, patterns appear. Repeated reports of pedestrians near the gate might lead to a new barrier. Several falling-object reports might trigger a review of exclusion zones. Your observations as a security officer, on nights, weekends and at the gate, fill gaps that daytime managers often miss.
