What actions are First Responders at Operations Level allowed to perform during a hazmat incident?

First responders at the Operations Level are specifically trained to perform defensive actions during a hazmat incident. This includes taking steps to protect their own safety and that of the public while preventing the situation from worsening. Examples of defensive actions may include containment or control measures, securing the area, and establishing perimeters to keep people away from the hazard.

The training also emphasizes that these responders operate within a framework of protocols designed to minimize risk; while they can engage in certain defensive measures, they are not permitted to engage directly with hazardous materials or conduct operations that require specialized knowledge or equipment on their own. This is critical to ensure safety, as more complex or specialized operations should be conducted by trained personnel at a higher level of response, such as HazMat Technicians.

The other options would represent actions outside the scope of what Operations Level responders are trained to do, such as direct contact with hazardous materials, conducting independent specialized operations, or assessing chemical properties, which require additional training and equipment. Thus, option B correctly reflects their authorized actions within the parameters set for their level of training and responsibility.
