Q

The success of an indirect attack on a fire depends on the __________.

🔍 Key Concepts

• Indirect attack uses water fog or spray applied into a closed space to create steam and smother the fire • For steam to displace oxygen effectively, the fire space and adjacent areas must be well sealed/contained • Consider what factor must be present for steam buildup and oxygen displacement to actually work

💭 Think About

• Ask yourself: In an indirect attack, where is the water being applied – directly on burning material or into the hot atmosphere of an enclosed space? • Which option describes a condition that MUST exist for steam to stay in the compartment long enough to put out the fire? • Which choice is more about the method of attack itself, rather than general fire properties like size or class?

✅ Before You Answer

• Verify which answer choice relates to keeping the fire compartment closed/sealed so steam cannot escape • Eliminate options that talk about fire characteristics (size, class) but not about the conditions required for an indirect attack to work • Make sure your choice matches the definition of an indirect attack: water turned to steam in a confined space to displace oxygen and cool surfaces
