Legislation for fire and smoke dampers and air duct systems

The British standard BS9999 code of practise for fire safety requires all ducting, whether it is for ventilation, heating or air conditioning to be fitted with dampers. It is now a legal requirement that all fire dampers to be checked periodically or yearly. Fire dampers play a crucial role in building fire systems, damaged or broken fire or smoke dampers could be the difference between life and death if there is a fire in your building. According to the Regulatory Reform (Fire Safety) order, it is the employer’s responsibility to maintain their fire safety systems. According to BS9999 all damaged or faulty smoke or fire dampers have to be replaced immediately.

There is a growing concern regarding the quality of air we breath from air conditioning, under COSHH regulations, Euro directives and the Health and Safety Executive it is your responsibility to ensure the health and safety of your occupiers whether workers, visitors, or tenants.

There is a great concern about the air that we breath from air conditioning. All air ducting must be cleaned yearly or more to be compliant with TR19. Dirty duct and air conditioning systems are the greatest cause of office sickness in staff. Dirty duct work can harbour debris and dust which encourage mould and bacteria to grow as the temperature is warm and humid. In recent tests in hospitals, the potential effects can be worse with MRSA and other infections taking hold.

Legislation for kitchen extract cleaning

The introduction of the regulatory reform (fire safety) order 2005 has created the legal requirements for all buildings to have a fair assessment undertaken, to comply with the legislation all fire hazards must be minimised, controlled or removed where possible. Since January 2006 it has been a law that supply and extract systems for food preparation areas must be cleaned in all European countries. Buildings that have kitchens, restaurants, or canteens will have grease extract systems, grease extract systems are deemed by the fire services and insurance industry to be one of the highest fire risk in any commercial building. All grease systems should be cleaned regularly in compliance with the (fire safety) order. Also the Health and Safety Executive, BSRIA, FPA insurance guidance and regulations stipulate that all kitchen extract systems should be kept clean to minimise fire and other risks. All the above is also overridden by the legal requirement to clean under the food standards agency. This law EC852/2004, which became law on 1st January 2006 and accordingly the Environmental agency will issue enforcement orders if necessary.

It is a known fact that only 5% of companies know that it is now a legal requirement for all kitchen extract systems to be cleaned periodically or yearly depending on the use of the system.
