This response can be backed up by ERT members if required and involves minimal outside assistance such as ambulance transport. The Emergency First Response includes: • BLS (basic life support) CPR at the workplace first aid level • AED (automated external defibrillator) use (optional) • preventing and caring for shock • spinal injury management • use of barriers to reduce disease transmission risk • basic first aid: illness & injury assessment, bandaging, management of fractures & dislocations, and first aid kit considerations • basic firefighting capabilities • Reconnaissance: information gathering, state of situation, key information to assist decision making. Site Security Site Security Guards are the first receivers of an emergency radio call, a request for mines rescue, 111 phone call or a request for the Site Medic. Security has relevant Duty Cards to prompt the critical first responses to specific incidents (Refer to Security Guard Duty Card and flow chart appendices) These are designed to be used by the Emergency Call Takers to ensure that vital notifications and actions are not missed during the initial part of an emergency situation. Back up Response Back up response is defined as external emergency service involvement and/or IMT activation: • any level 2 trigger where first response has been ineffective and immediate advice and support is required from Oceanagold personnel who are not on site at the time; • any trigger which requires evacuation of an area, major external emergency service involvement or the forming of the Incident Management Team; • all level 3 response triggers Incident Management Team The Incident Controller (IC) will assemble the Incident Management Team (IMT) based on the information they receive. The IC will declare the incident a level 3 if required and follow the appropriate steps. Guidance on when emergencies escalate from levels 1, 2, or 3 can be referenced in the Trigger Action Response Plans and Risk Assessment Guidelines.
