Exclusion zone

Establishing exclusion zones when using explosives in demolition, Construction Information Sheet No 45, published by the Health and Safety Executive (HSE) states in relation to an exclusion zone: ‘When designing for demolition using explosives you need to plan for the possible fly of projectiles. An exclusion zone should be established at a distance from and surrounding any structure which is being demolished using explosives. The zone needs to be designed and managed as part of the overall approach to the demolition. People outside the exclusion zone should be safe from the demolition work. Everyone, with the possible exception of the shotfirer, should be outside the exclusion zone at the time of the blast. If the shotfirer needs to remain within the zone, he or she should be in a safe position.’

An exclusion zone is built up from four areas:

• Plan area.
• Designed drop area.
• Predicted debris area.
• Buffer area.
