When BPUB activates its General Emergency Plan, the company responds according to plans established by FEMA which include the Incident Command System (ICS), the standard for emergency management by all public agencies in the United States for both planned and emergency events. This organizes personnel under one leader toward a common task, improving communication and ensuring a more organized response. That may expand or contract based on the magnitude of the incident, a hallmark of ICS. Businesses with organized emergency response teams that interface with public emergency services can benefit from using the ICS. ICS is also well suited for managing disruptions of business operations. Public information and crisis communications are an integral part of the ICS structure.
