What is the main concern when approaching a hazardous materials incident?

The primary concern when approaching a hazardous materials incident is ensuring personal safety and identifying containment measures. In hazardous situations, first responders must prioritize their safety to prevent injury or exposure to harmful substances. This involves conducting a risk assessment, establishing a safe perimeter, and using appropriate personal protective equipment (PPE).

Additionally, identifying containment measures is crucial to mitigate the spill or leak and prevent further contamination or damage. This includes understanding the properties of the hazardous material and the appropriate techniques for containment and cleanup. Safety protocols and clear communication among responders are vital components of an effective response strategy.

The other options pertain to aspects that, while important, do not take precedence in the immediate response to hazardous materials incidents. For instance, ambulance dispatch times and cleanup cost estimations are secondary considerations that come into play after ensuring the safety of personnel and properly assessing the situation. Knowing the type of damage to vehicles may be relevant in the context of a broader incident response but does not directly address the immediate concerns of safety and containment at a hazardous materials incident.
