Activate and operate a PKP fire extinguisherIntroduction
Dry chemical powders do not smother or cool, but they interrupt the chemical reaction.
The most common type of dry chemical powder is potassium bicarbonate, also known as Purple-K-Powder, or PKP. Most PKP extinguishers have a small CO2 cartridge mounted on the outside of the extinguisher shell.
Those extinguishers are primarily used to extinguish class B (Liquid fuel) and class C (gas fuel) fires. Alternatively it can be used for class A fires, also, although it is not very effective and can be used to knock down flames and keep the fire under control until an appropriate extinguisher can be used. PKP can be used in conjunction with AFFF.
However, they are both corrosive and abrasive and should be used on electrical fires or on Main Engines and machinery only in emergencies because they tend to destroy completely circuitry and equipment.

PKP – Potassium Bicarbonate
for class B and class C fires
For best results in conjunction with AFFF
Corrosive and abrasive
Avoid using in electrical fires
Avoid using on Engines and machineryMain characteristics of dry powder
• After the extinguisher is out, there is nothing to prevent the chemical reaction so there is an increased danger of reignition
• Combination with AFFF results in cooling, too, thus providing better results
• Dry powder extinguishers are quite messy and leave many left overs of corrosive material, especially harmful for electrical devices
• Fast extinguishing capabilitiesmain characteristics of dry powder

Step 1: Check pressure gauge
Step 2: Check to see if extinguisher is full
Step 3: Remove the safety pin
Step 4: Check operation by pressing the activation lever
Step 5: Aim at the base of the fire
Step 6: Use quick bursts especially in enclosed areas
Step 7: Keep approx. 3-4 m away from the fire
