The phrase "wash down" is widely used in contexts involving decontamination or neutralization of hazardous materials. This term typically relates to the processes used to remove harmful substances from surfaces or areas to ensure safety. In the context of handling hazardous materials, "wash down" refers specifically to the action of using water or specialized cleaning agents to rinse surfaces that may have been contaminated. This is particularly crucial in situations involving chemical spills or exposure to toxic substances, as thorough washing down of affected areas helps prevent further hazards to human health and the environment.

While cleaning evidence at a crime scene, clearing debris after a disaster, or washing police vehicles all entail cleaning actions, they do not necessarily invoke the same critical safety measures associated with hazardous materials. Therefore, the focus on safety and contamination in handling hazardous materials makes this context the most appropriate for the usage of "wash down."
