When under attack, when should the warning be given?

• A. Before putting on the mask
• B. After you put your mask on
• C. While removing the mask
• D. Simultaneously with the attack

Answer: (B)

The correct response indicates that the warning should be communicated after putting on the mask. This timing is crucial for ensuring personal safety and the ability to respond effectively in a threatening situation. Once the protective mask is secured, the individual can then focus on relaying the warning to their peers, ensuring that everyone is informed while minimizing their exposure to potential dangers, such as chemical agents or other hazardous environments.

Issuing a warning before securing the mask would leave the individual vulnerable, as they might be exposed to harmful substances while trying to communicate. Similarly, attempting to give a warning while removing or during an attack may create confusion or increase risk to oneself or others. By prioritizing the donning of the mask first, personnel can better protect themselves before alerting others to the imminent threat.
