NFPA Portable Fire Extinguishers (NFPA 10) Practice Exam

Question: 1 / 400

Which type of fire extinguisher does not require a six-year internal maintenance?

Cartridge operated dry chemical

Stored pressure dry powder

Stored pressure halogenated agent

Stored pressure water

The type of fire extinguisher that does not require a six-year internal maintenance is indeed the stored pressure water extinguisher. According to NFPA 10, stored pressure water extinguishers are generally subject to less stringent maintenance requirements compared to other types like dry chemical extinguishers.

One crucial factor is that stored pressure water extinguishers contain water as the extinguishing agent, which does not degrade over time or require the same level of internal inspection that other extinguishing agents might need. This means they can often remain functional without the internal maintenance that dry chemical or halogenated agents require, which may involve inspecting and potentially recharging the units to ensure optimal performance.

Understanding the maintenance requirements of different types of extinguishers is essential for proper fire safety management and compliance with regulations.
