The length and extent of the health and safety risk assessment is determined by the complexity of the venue, facilities or event. For a simple venue or event, a standard risk assessment is sufficient. This would take into account any risk factors , addressing specific issues that may arise day to day or at the event, that could endanger staff, guests and anyone else who could be impacted.
For complex scenarios, you may need a Safety Management Plan or a Safety File. You could also hire a Safety Advisor to ensure that all ideas are taken into account.
To manage risk, any exposures should be identified and analysed. Risk management techniques should be examined, an appropriate technique selected and implemented, and the results monitored.
