Evacuate and Alert

When faced with a Class D fire, which involves metals, it is important to know how to use a Class D fire extinguisher correctly to evacuate and alert others. The first step is to immediately sound the fire alarm and call for emergency assistance.

Evacuate the area and make sure everyone is out of harm’s way. Then, locate the Class D fire extinguisher and pull the safety pin.

Select the Appropriate Extinguisher

It is crucial to select the appropriate extinguisher based on the type of metal involved in the fire. To use a Class D fire extinguisher, one should first read and ensure that the extinguisher is within its expiration date.

Take note that it should also be clearly labeled as such. These labels should be checked regularly to assure of a working extinguisher. Otherwise, make sure to contact a fire extinguisher service to replace you with a new one.

Approach with Caution

When dealing with a Class D fire, it is important to approach the situation with caution and follow proper safety procedures. These types of fires involve combustible metals such as:

  • magnesium
  • titanium
  • sodium

Approach the fire carefully and aim the nozzle of the extinguisher at the base of the flames. Make sure there is a safe distance and an exit path behind you.

Aim at the Base

Point the nozzle of the extinguisher at the base of the fire. Do not aim it at the flames themselves, as this can cause the burning metal to scatter and potentially spread the fire.

This means directing the nozzle towards the source of the fire rather than the flames themselves. Aiming at the flames can actually cause the burning metal to scatter and spread the fire further.

By targeting the base of the fire, the extinguishing agent can smother the fire and prevent it from reigniting. This method is crucial in effectively extinguishing a Class D fire.

Squeeze and Sweep

Squeeze the handle of the extinguisher to release the extinguishing agent (typically a dry powder designed for use on metal fires). Sweep the agent back and forth across the base of the fire. Do this while covering the entire area with the extinguishing agent.

Learn How to Use a Class D Fire Extinguisher

Knowing how to properly and safely use a Class D fire extinguisher can be life-saving in the event of a fire involving combustible metals. Remember to always read the instructions on the extinguisher and practice using it before an emergency arises.
