How often should Type B extinguishers be visually inspected?

Type B extinguishers, which are designed to extinguish flammable liquids and gases, should be visually inspected on a monthly basis. This frequency ensures that any potential issues, such as pressure loss, damage, or obstruction, are identified and addressed in a timely manner.

Regular monthly inspections provide a routine check to ensure that the extinguisher is in its designated location, readily accessible, and that the pressure gauge reads within the operational range. Maintaining this monthly schedule helps to guarantee the effectiveness of the extinguisher when it's needed most, as extinguishers are crucial for safety in environments where flammable materials are present. The annual service typically refers to more thorough inspections and maintenance, while daily and weekly checks are generally not necessary for Type B extinguishers.
