Event Risk Assessment

How do you run an event risk assessment?

An event risk assessment is a structured look at what could go wrong at your event, how likely each problem is, how bad it would be, and what you will do to prevent it or cope with it. The result is a risk register: a short table of risks, ratings, controls and owners that the whole team can read and use.

You do not need special training to start. You need the people who know the event in one room, a method for rating risks, and a habit of reviewing the register as plans change. This guide walks through the steps, gives a register you can copy with example rows, and outlines an emergency plan. It is general guidance only. Rules and expectations differ by place, venue and type of event, so check with your local authority, your venue and your insurer about what applies to you.

What an event risk assessment is for

The point of a risk assessment is to make decisions before the event, when changing the plan is cheap. It makes the team name risks out loud, assign someone to each one and agree what will be done if it happens. It also gives your venue, insurer and local authority something concrete to review, if they ask for it.

Keep it proportionate. A small meetup needs a page. A multi-day conference or an outdoor festival needs more detail and may need input from specialists such as safety advisers or medical providers. If you are unsure how much is expected for your event, ask the venue and the local authority early.

Think of risk in groups so nothing is missed: people (attendees, staff, speakers, volunteers), place (the venue, access, weather, crowds), things (equipment, power, technology, suppliers), money (cancellations, payment failures, budget overruns) and reputation (a poor experience, a public mistake, a data problem). Walking through each group with two or three colleagues who see the event from different angles, such as registration, program and venue liaison, turns up risks that one person alone would not list.

Finish with a decision about what you accept. Some low-rated risks are fine to leave with no action, as long as someone has seen them and said so. Write that down in the register, so the reasoning is clear if you are asked about it later.

The steps to run a risk assessment

Follow these steps in order. Most events can complete them in a working session or two:

  1. Describe the event

    Write down the dates, location, expected numbers, audience, activities, suppliers and anything unusual such as VIP guests, alcohol or outdoor areas.

  2. Identify the risks

    Walk through the event from arrival to departure and ask what could go wrong at each point. Include people, place, equipment, weather, money, reputation and information.

  3. Rate likelihood and impact

    Give each risk a score for how likely it is and how serious the effect would be, using the same simple scale for all of them.

  4. Decide on controls

    For each significant risk, decide what you will do to prevent it, reduce it or prepare for it, and by when.

  5. Assign an owner

    Every risk and every control needs one named person responsible, not a team.

  6. Agree the emergency plan

    Write down who does what in an emergency, how people are told, and who talks to emergency services, the venue and the media.

  7. Brief the team

    Walk staff, volunteers and key suppliers through the plan before the event, and make sure they know who to call.

  8. Review and update

    Revisit the register at set points: after major changes, a week before, on the morning of the event and after it.

Rating likelihood and impact

A simple scale is easier to use than a clever one. One common approach is to score likelihood and impact from 1 to 5 and multiply them to get a rating. Whatever scale you choose, define each level in words so two people would score the same risk the same way.

A simple scoring guide (adapt to your event)
ScoreLikelihoodImpact
1Very unlikelyMinor inconvenience, no lasting effect
2UnlikelySmall disruption, easily fixed
3PossibleNoticeable disruption or cost
4LikelySerious disruption, significant cost or harm
5Almost certainSevere harm, event stopped, major financial or legal consequences

A risk register you can copy

A register keeps everything on one page. The example rows below are examples only, written to show how a row reads. Your real risks depend on your event, your venue and where it takes place, so replace them with your own.

An emergency plan outline

The risk register says what you will try to prevent. The emergency plan says what everyone does when something happens anyway. Keep it short enough that a volunteer could use it under stress, and base the specifics on what your venue and local authority tell you.

  • Who is in charge

    Name an incident lead and a deputy for each shift, with phone numbers, and tell the whole team who they are.

  • How to raise the alarm

    Decide how staff report an incident, who calls emergency services, and how the venue's own procedures fit in.

  • Evacuation and assembly

    Get exits, assembly points and any evacuation procedures from the venue, put them in the briefing and check that staff know them.

  • First aid and medical

    Agree what arrangements are needed and in place with the venue and, if required, your local authority and insurer.

  • Communicating with attendees

    Decide who can make announcements, by what means, and what the standard messages are.

  • Keeping records

    Note times, decisions and people involved in any incident, and report to the venue and your insurer as they require.

Where your event data helps

Eventdex is not a safety or risk management system, and it does not replace the advice of your venue, local authority, insurer or a qualified adviser. What it provides are the attendance records that make several risks easier to manage.

  • Know who is expected

    Registration data gives the numbers by ticket type, so crowd and capacity risks are based on facts.

  • A back-up when the network fails

    Eventdex's check-in page describes an offline mode that stores check-ins on the device and syncs when the connection returns, which can help if the network fails at the door. Keep your own back-up list as well.

FAQ

Event Risk Assessment: common questions

What is an event risk assessment?

It is a structured review of what could go wrong at an event, how likely and how serious each risk is, what will be done about it and who is responsible. The result is usually a risk register plus an emergency plan.

Do I need to do one for every event?

Requirements depend on where you are, the venue and the type and size of event, so check with your local authority, venue and insurer. Even when none is required, a short assessment is a sensible habit.

Who should be involved in the assessment?

Include the people who know the event: the organizer, the venue contact, operations, registration, program and any safety or medical lead. For larger or higher-risk events, bring in qualified specialists.

How often should the risk register be updated?

Review it whenever the plan changes in a way that matters, such as a new venue, a new activity or a different crowd size, and again in the week before, on the day and after the event to record what you learned.

Does Eventdex provide risk assessments or safety planning?

No. Eventdex does not provide safety or risk management. It provides registration, check-in and event app tools, and the attendance data they hold can inform your own assessment.
