What should be done first in case of a hazardous materials spill?

In the event of a hazardous materials spill, the primary action to take is to notify DC Central or the Officer of the Deck (OOD). This step is crucial because timely and effective communication ensures that the appropriate response team can be mobilized to manage the incident. The OOD has the responsibility to coordinate efforts to secure the area, initiate safety protocols, and provide guidance on containment and cleanup actions.

Once notification is made, the next steps of response can be implemented. This allows trained personnel to assess the spill and execute proper procedures for safety, such as posting safety watches to keep others away from the danger zone, ventilating the area, or properly handling the hazardous material. However, these actions depend significantly on first establishing command and control, which starts with notifying DC Central or the OOD.
