Is there a maximum sound level for fire alarms?Įxcessive sound pressure levels can cause disorientation or even damage to hearing. Your best option would be to check with your local planning office to ensure you’re compliant. However, there are certain transitional arrangements in force depending on the planning approval dates that may mean you do not have to comply. In terms of sprinklers in 2014 Approved Document B was updated by the Welsh Assembly to say that from January 2016 automatic fire sprinklers were to be made compulsory in all new and converted residential properties in Wales.
In 2011 responsibility for the Building Regulations in Wales was handed to the Welsh Assembly which means they have the choice to uphold the UK Building Regulations or make changes specifically for Wales.
We’re in the process of building a residential development in South Wales and we’ve been told that all residential properties now require automatic fire sprinkler systems? Having looked at Approved Document B for the Building Regulations we can’t seem to find these requirements.įirstly, it should be pointed out that the UK Building Regulations are not necessarily applicable in Wales as they are in the rest of the UK. This document references BS 9990:2006 as the main regulation for dry risers (referred to as dry fire mains) but there is a more recent version, BS 9990:2015. What is the legislation for positioning dry risers in enclosed areas within buildings such as stairwells?Ĭurrently the legal guidance is documented briefly on section 15, page 107 of the latest Approved Document B (fire safety) of the Buildings Regulations.
