Which of the following is a response action for a beryllium fire?

Using dry chemical extinguishers is the appropriate response action for a beryllium fire due to the specific nature of how beryllium reacts during combustion. Beryllium fires can be particularly challenging, as water and foam extinguishers are ineffective and can even exacerbate the situation by causing a violent reaction. Dry chemical extinguishers are designed to suppress fires without creating additional hazards, making them suitable for metals like beryllium.

When dealing with a beryllium fire, it is essential to utilize materials that can effectively control the fire without introducing complications that may arise from chemical reactions. Dry chemical agents can smother the flames and remove the heat without the risks associated with other methods. This is critical for ensuring safety in environments where beryllium is present, as it helps to prevent the fire from spreading and reduces the likelihood of toxic fumes being released.
