Pipe insulation should have a maximum flame spread index of what value?

1. 50

2. 25

3. 75

4. 100

The correct answer is: 25

The maximum flame spread index for pipe insulation is crucial for fire safety and prevention. The correct value, 25, indicates that materials with this flame spread index will limit the spread of flames effectively in case of a fire. Lower values represent better fire safety properties, meaning the material does not burn or propagate flames as readily as materials with higher indexes. This standard is particularly important in building codes and fire safety regulations, which aim to reduce potential hazards in both commercial and residential settings. Utilizing materials with a flame spread index of 25 or lower helps ensure that insulation contributes to overall fire safety, providing occupants with more time to evacuate and reducing the potential for extensive property damage. Materials with a higher flame spread index, such as those closer to 75 or 100, do not meet the fire safety criteria as effectively and could pose a greater risk during a fire incident. Therefore, the selection of insulation materials with a maximum flame spread index of 25 is a critical requirement in achieving compliance and enhancing safety measures in facilities with low pressure boilers.
