What is the term for the mode of operation where responders have direct contact with hazardous materials?

The term that refers to the mode of operation where responders have direct contact with hazardous materials is "Offensive Mode." In this mode, emergency responders actively engage with the hazardous situation to mitigate or eliminate the threat. This can involve tasks such as containing spills, neutralizing chemical hazards, and directly tackling the source of the hazard.

Choosing this approach requires specialized training, appropriate protective gear, and adherence to safety protocols, as responders are at higher risk of exposure to dangerous substances. The offensive mode is typically employed when responders assess that the situation allows for safe intervention to control or remove the hazard effectively.

In contrast, defensive strategies focus on protecting people, property, and the environment from the effects of hazardous materials rather than directly confronting the hazard itself. This distinction is crucial in emergency response, as it dictates the level of risk responders are willing to accept in handling hazardous materials.
