Wetting agent portable extinguishers require hydrostatic testing every how many years?

Wetting agent portable extinguishers are designed to combat Class A fires by reducing the surface tension of water, allowing it to penetrate materials more effectively. The required interval for hydrostatic testing of these extinguishers is every five years. This testing ensures that the extinguisher can withstand the pressure it will be subjected to when used, helping to maintain safety and functionality.

This five-year interval is consistent with industry standards, which seek to ensure that equipment remains reliable and effective in emergency situations. Regular testing helps detect any potential weaknesses or deterioration in the extinguisher's structure, thus ensuring that users can depend on it when needed. Such rigorous maintenance standards are vital for fire safety compliance and the overall effectiveness of fire-fighting resources.
