What is one of the responsibilities of truck companies?

One of the key responsibilities of truck companies is to conduct building ventilation procedures. This task is vital during fire incidents to control smoke, heat, and toxic gases, enhancing visibility and creating a safer environment for both occupants and firefighters. Proper ventilation helps in reducing the risk of flashover, improves conditions inside the building, and can significantly affect the outcome of firefighting operations.

Ventilation is often performed by opening windows, doors, or using specialized equipment to remove smoke and heat from the structure. This operation is critical in high-rise buildings, where smoke can rapidly accumulate and create hazardous conditions. By effectively managing ventilation, truck companies improve the survivability of trapped occupants and assist in more efficient firefighting efforts.

The other options reflect important tasks that may be associated with other emergency response teams or specialized units, not primarily truck companies. For instance, coordinating hazardous material responses generally falls under the jurisdiction of hazmat teams, managing water supply is typically the role of engine companies, and performing medical assessments is usually assigned to medical teams or paramedics.
