Product guide
The 4kg DCP fire extinguisher refill is designed to help maintain the operation of a dry chemical powder fire extinguisher after it has been used in a fire event, or when the manufacturer's recommended maintenance schedule calls for the fire extinguisher to be refilled. If a fire extinguisher was previously discharged, or if it was not correctly refilled with the correct amount of dry chemical powder, then there is a risk that the fire extinguisher will not function properly when needed most in an emergency. Therefore, regular inspections of all fire extinguishers should occur; if any issues are identified, such as the need for refilling, then the fire extinguisher must be professionally refilled as soon as possible. With the Sensato Trade website, users can order 4kg DCP fire extinguisher refills quickly and easily online. Users can also use the Sensato Trade site to inquire about the availability of professional services to inspect and assess the condition of their current fire extinguisher cylinders to determine if refilling is necessary. Users can arrange for professional services to come out and inspect their fire extinguisher cylinders, assess their conditions, and make recommendations regarding whether the cylinders need to be refilled.

How to refill fire extinguisher?
Refilling a fire extinguisher is a risky process and it need to be done by the professional. Avoid attempting at home or handling by the trained person.
