Common Questions Answered:
- Is fire safety a legal requirement? If you’re responsible for a building, it’s important to do all you can to reduce the risk of fire to keep people safe. It saves lives, it’s your legal duty, and it makes good business sense.
- Do the Fire Safety Regulations apply to your building? The regulations apply to existing multi-occupied buildings, with differing duties applying to buildings of differing heights.
- Do new fire regulations apply to existing buildings? The regulations apply to existing multi-occupied buildings, with differing duties applying to buildings of differing heights.
- Do all flats need a fire risk assessment? Yes, all blocks of flats must have a fire risk assessment by law. If your flat has more than four residents at any one time, you must have a written record of this fire risk assessment. However, even if you have less than four residents, we still recommend that your fire risk assessment is recorded in writing.
- What is the 11 meter rule? Responsible persons in multi-occupied residential buildings which are above 11 metres in height, and in high-rise buildings need to provide additional safety measures.
- What is the fire safety Act 2024? As the UK continues to prioritise fire safety, the anticipated changes in fire regulations and safety measures for 2024 aim to enhance building safety, ensure accurate risk assessments, promote fire safety education, strengthen regulatory oversight, and address external wall fire safety concerns.
- What is the difference between approved Document B and BS 9999? While ADB offers guidance on meeting building regulations in typical scenarios, it may not adequately address complexities or larger-scale buildings. BS 9999 adopts a holistic approach to fire safety, permitting compensatory measures to address factors like travel distances or escape door widths.
