Presented by

Mick Leadbetter

Fire Safety Adviser

• Merry Hill covers 125 acres having 1.5 Million Sq Mtrs of retail space on two levels that are continually being developed.

• There are some 220 smaller units and 10 blue chip anchor stores.

Background

• Merry Hill Is Not One Building.

• It Has 16 Major Smoke Zones Which Can Be Evacuated In Isolation or Simultaneously.

• For Example, There Could Be A Fire In Marks and Spencers, But Because of The Fire Shutters and various Smoke Control Systems in Place, Customers Could Still Shop Safely In Adjacent Stores.

Why Such Facilities?

• Building Regulations ADB2000.• Requirements of British Standard 5588, Part

10, 1991 (Code of Practice for Shopping Centres).

• N.B. Previously the Town Centre Re-development Guide was used for this type of premises.

• British Standard 5588, Part 11, 1997 (Code of Practice for Shops, Offices, Industrial Storage and other similar buildings.

• Fire Precautions (Workplace) (Amendment) Regulations (1999).

Legislation

• Merry Hill, Landlord areas and various stores have a current Fire Certificate in place further A Fire Risk Assessment under the Amended Workplace Regulations has been carried out To both Landlord and Tenant Areas.

• Some 30 Landlord Fire Exits are in place, also except for small kiosks all retail shops have alternative Means of Escape Facilities via back of house escape corridors which given the 20 Million customer visits per year it is imperative are maintained.

• Merry Hill Landlords Fire Risk Assessment was the first of such a size to be completed in the West Midlands Fire Service area and was used as a benchmark for other premises.

Future Legislation• Government proposes that the Fire Service

will no longer issue Fire Certificates.• Building Managers will need to carry out

comprehensive Fire Risk Assessments considering amongst other things Means of escape, Fire Alarm, Sprinklers, Smoke,Shutters, training etc.

• Plans may need to be included.• On completion formal Fire Authority validation

may be required.• ARE YOU READY FOR THIS CHANGE!
