How do you put out a pressure fire?

To extinguish a pressure fire, first, ensure your safety by moving away from the source and calling emergency services. If safe to do so, try to shut off the pressure source, such as a valve. Use a fire extinguisher appropriate for the type of fire (e.g., CO2 or foam) to suppress the flames, aiming at the base of the fire. Avoid using water, as it can spread flammable liquids and may exacerbate the situation.
