At an individual site level, there should be an identified senior member of staff who is able and capable of leading the response to an emergency/crisis event. Ideally, there should be more than one person and deputies should also be available. This role should be pre-agreed and clearly identified. The site should always have the ability to enact this role immediately. The person(s) identified to take this role should be trained and they should undertake regular testing. Best practice would demonstrate site crisis response leaders have received training and have been tested. This will be documented and recorded​
