Learn the difference between fire protection ratings and fire resistance ratings, and how they affect the design and construction of buildings. NFPA 1, Fire Code, provides guidance on the requirements and limitations of these ratings. Read the latest blog post from NFPA, the authority on fire, electrical and related hazards.
About Photovoltaic Energy StorageThe higher the rating of the fire door, the longer the fire will be held back - fire doors are available with fire ratings of up to 240 minutes. Choosing to install FD60 fire doors when only FD30 doors are required can also ''future proof'' the building against changes to regulations, or changes to the use and occupancy of the building.
About Photovoltaic Energy StorageFire-resistant matting is an often overlooked but essential part of fire safety in any building.
