When parking your ambulance at a potential haz-mat scene, you should secure the ambulance:

• A. Uphill, Upwind, Upstream.
• B. Downhill, Downwind, Downstream.
• C. On level ground away from the scene.
• D. Behind the incident and blocking primary access.

Answer: (A)

At a hazmat scene, protect yourself by parking uphill, upwind, upstream. This positioning uses terrain and air movement to keep any released material away from the ambulance and crew. Being uphill reduces the chance of liquid runoff reaching the vehicle, while being upwind ensures vapors are carried away by the wind rather than toward the cab. Being upstream places you against the flow path of any contaminant moving with a liquid or gas, so the material tends to move past you rather than into your shelter. Together, these factors minimize exposure and keep access routes and decontamination operations safer. Parking in a downhill, downwind, or downstream position increases the risk that contaminants will reach or pool near the ambulance.
