Firefighter 1C Wildland Practice Exam

Which of the following criteria is NOT used to determine an engine's ICS type?

1. Pump rating

2. Water tank capacity

3. Gross vehicle weight

4. Hose compliment

The correct answer is: Gross vehicle weight

The correct answer relates to the criteria used to determine an engine's ICS (Incident Command System) type based on their operational capabilities in firefighting and other emergency responses. When assessing an engine's type, essential criteria such as pump rating, water tank capacity, and hose compliment are considered because they directly influence the engine's ability to deliver water and respond effectively to wildland and structural firefighting situations. The pump rating indicates the engine's capacity to pump water, which is critical for firefighting operations. Water tank capacity is important as it determines how much water the engine can carry onboard for immediate deployment without the need to refill from a hydrant or another source. Hose compliment refers to the amount and size of hose the engine carries, which is also necessary for effective firefighting. In contrast, gross vehicle weight does not provide relevant information about the engine's operational capabilities concerning firefighting effectiveness. While weight may be a factor in terms of vehicle regulation and transport, it does not impact the engine's performance or suitability for an incident type under ICS. Therefore, it is not a criterion considered for determining an engine's ICS type.
