Question 1 of 27070

When using a dry chemical type fire extinguisher in a windy location, you should direct the stream from __________.

🔍 Key Concepts

• Wind direction and spray/stream pattern when using portable extinguishers • Behavior of dry chemical (powder) in moving air versus still air • How to position yourself so the agent reaches the base of the fire instead of blowing back

💭 Think About

• If the wind is blowing from your right to your left, where should you stand relative to the fire so the chemical cloud moves into the flames, not into your face? • Think about which direction lets the wind help carry the extinguishing agent onto the fire, instead of dispersing it away. • Where would you aim the nozzle so that you can safely sweep the base of the fire without the wind immediately blowing the powder away?

✅ Before You Answer

• Confirm which side of the fire is upwind vs. downwind based on where the wind is coming FROM, not where it is going TO. • Visualize the cloud of dry chemical: which direction will it travel once it leaves the nozzle in that wind? • Check which option best ensures the chemical reaches the base of the fire and does NOT blow back into the operator’s face.
