As specialist mezzanine floor designers and installers, we are very conscious of the safety requirements of mezzanine floors. Your safety is our top priority and we have a duty to make sure that your mezzanine floor is completely safe. It must comply with the Building Regulations – specifically, parts A, B, K and M. If you would like more details, then you’ll find the approved documents here.

Part A – Structure

Your mezzanine floor must be able to support itself and any equipment or people you have on there. We will work with you to come up with a design that meets your requirements and will adhere to all structural regulations. Your floor slab must be made of suitable material to support the structure and your columns must be spaced out in such a way that the floor is evenly supported.

Your mezzanine floor must also be designed to resist disproportionate collapse, which is when the collapse of a structure occurs after a disproportionately small accident. The minimum floor loading requirements as set out by British Standards BS6399 depend on the application of the floor:

  • Office Use: 3.5kn/m²
  • Standard storage application: 4.8kn/m²
  • Heavy duty application: 9.6kn/m²

Part B – Fire Safety

One of the greatest risks to buildings is fire, especially when you have the close proximity of electricals. Your mezzanine floor must have a fire warning system in place that alerts people as soon as a fire or smoke is detected. At Mezz Floors, we offer responsive smoke detectors and sprinkler systems to ensure you are alerted and that the fire is fought as soon as possible.

Building Regulations stipulates that if your floor has a surface area greater than 400m², if it equates to more than half the floor area of the room it is in, or is used for anything other than maintenance or storage, then the underside must have a one-hour fire rating. We will ensure that fire-resistant materials are used in the construction of your mezzanine floor.

Other fire safety features could include suspended ceilings, column casings and firewalls. Finally, your floor must not prevent the emergency services from tackling a fire – we will analyse the building layout carefully when designing the mezzanine floor and placing it.

Part K – Protection Against Falling

Given the raised nature of mezzanine floors, it is essential that your employees, customers and other visitors are sufficiently protected from falling. This means secure handrails and balustrades for when people are walking around on your mezzanine floor. Also, if your mezzanine floor is going to be used for loading, then safety pallet gates will ensure that your employees are kept safe while carrying out their work. You must have safe and secure general access stairs. Our mezzanine floor systems are designed with robust protections in place to keep you safe.

Part M – Accessibility

The Building Regulations stipulates that your mezzanine floor must have reasonable means of accessing it. You may also need to ensure wheelchair accessibility, depending on what your floor is going to be used for. For instance, if your mezzanine floor is for a retail business, you must ensure that it is accessible by wheelchair.
