English operating and maintenance guidance for portable water-based extinguishers used for building safety, offices, public facilities and selected early-stage fire risks.

Operating Method

  1. Carry the extinguisher to a safe position and keep it upright.
  2. Pull out the safety pin.
  3. Aim the nozzle at the base of the flame.
  4. Press the handle to discharge the water-based agent.
  5. Sweep the stream across the burning surface until the fire is controlled.
  6. Continue monitoring the area for reignition.

Product overview and application

Portable water-based extinguishers are designed for everyday building protection and selected initial fire scenarios. They are often used in offices, public facilities, commercial areas and general service spaces.

  • Water-based agents are commonly used for Class A fire loads such as ordinary combustibles.
  • Use on liquid or electrical fires only when the product label allows it.
  • The agent formulation and temperature range must match the storage environment.

Main structure and working principle

The unit includes a cylinder, valve head, pressure indicator, nozzle or hose, water-based extinguishing agent and driving gas. Pressing the handle opens the valve and releases the agent through the nozzle.

  • The pressure indicator should be in the normal range before use.
  • The nozzle must be clear and undamaged.
  • Do not mix agents or refill without authorization.

Storage and routine inspection

Store the extinguisher in a dry, accessible location within the permitted temperature range and away from corrosive atmosphere, direct sunlight and heat.

  • Prevent freezing if the product is not formulated for low-temperature use.
  • Check pressure, seal, pin, hose, nozzle and cylinder condition.
  • Remove from service if leakage, corrosion, low pressure or label damage is found.

Service and Maintenance Checks

  • Use an authorized maintenance organization for repair and recharge.
  • Inspect the cylinder and valve assembly before maintenance.
  • Replace seals, gaskets and the water-based agent during required service.
  • Check the filter, nozzle, hose and pressure indicator.
  • Hydrostatically test pressure parts where required.
  • Recharge only with the approved water-based agent and specified driving gas.

Important Safety Notes

  • Do not use on energized electrical equipment unless the label explicitly permits it.
  • Do not store outside the approved temperature range.
  • Do not expose the cylinder to direct heat, impact or corrosive substances.
  • Follow local fire code and site emergency procedures.
