What guidance does NFPA provide concerning hot work for protecting buildings under construction or renovation?
June 6, 2025
Hot work should only be done in areas that are designated as fire safe.
What NFPA standards address fires in buildings under construction or renovation?
June 6, 2025
NFPA research identifies fire origin and other details for a variety of fire and safety hazards.
Are different types of hoods needed in commercial cooking operations?
May 2, 2025
Commercial cooking equipment that produces various types of exhaust must be protected with a hood.
Do all commercial cooking installations require hood-duct and automatic extinguishing system protection?
May 2, 2025
An underwriter recently asked if a certain cooking installation needed a complete hood-duct and automatic extinguishing system.
Do NFPA and UL provide guidance for installation and use of heat tracing in automatic sprinkler systems for areas exposed to freezing?
April 1, 2025
NFPA 13, the automatic sprinkler system Standard, allows for heat tracing systems to protect areas of sprinkler piping exposed to low temperatures.
Are there alternatives to antifreeze loops for automatic sprinkler systems in areas exposed to freezing?
April 1, 2025
Anti-freeze systems were discussed as a good alternative to protect relatively small areas of a wet pipe sprinkler system exposed to temperatures 40°F or lower. However, there are cases where antifreeze loops could be of limited use, primarily in climates that experience very low temperatures.
How are outside areas of a building protected by an automatic sprinkler system without threat of freezing pipes?
January 30, 2025
The importance of protecting all areas of a commercial building with an automatic sprinkler system is well recognized with specific guidance provided by NFPA 13.
Why is it important to protect covered outside areas of a building with an automatic sprinkler system?
January 30, 2025
Insurance companies often give premium reductions to insureds whose buildings are protected by automatic sprinkler systems. This recognizes the critical role sprinkler systems provide in reducing a loss in the event of a fire in the structure.
Can a change in occupancy affect the efficiency of an automatic sprinkler system?
December 23, 2024
When a building’s occupancy changes, there can be significant impacts on the ability of the automatic sprinkler system to control a fire.
Why is it important to understand hazard classifications in the design of automatic sprinkler systems?
December 23, 2024
As discussed in a previous (06/14/2023) Underwriters’ Corner, various NFPA Standards and Codes use occupancy and contents hazard classifications to determine the amount of fire protection to be provided for various occupanices and structures.
