Initial operations should include conferring with the Incident Commander and determining if any individuals need to be rescued or evacuated. b. Batteries should always be treated as energized, and contact with high voltage components should be avoided. c. The ACRE (Assess, Control Hazards, Rescue, Evacuate) approach should be used for quick evaluation of the incident scene. d. Control hazards by securing the area, isolating and denying entry, and establishing control zones based on hazards. e. Rescue operations should use appropriate methods and equipment to separate unprotected personnel and civilians from hazards. f. Risk assessment for battery emergencies should consider the hazards, the ability to control them, the likelihood of harm, and the expected benefit of intervention. g. For electric vehicles, consult the manufacturer guide, consider non-intervention for fire involvement, and protect infrastructure and adjacent property. h. For interior and exterior ESS, establish control zones, restrict operations to immediate life safety needs, and ensure technical specialists are enroute.
