About Emergency Response

Members of BASES Emergency Preparedness maintain exceptional emergency management plans that are based on assessments of risks associated with their respective materials, processes and equipment.  Low probability / high consequence scenarios are studied to prevent emergencies but also prepare response solutions that can minimize impacts of events and expedite recovery as required.

Relevant aspects of emergency plans and procedures are shared with employees, contractors, and neighbours.  A significant element of BASES Emergency Preparedness in our region is cooperation and coordination of our member site response teams to:

  1. Local government response teams; and
  2. Response teams from other member sites.

An emergency at a BASES member site is addressed from a regional perspective to maximize effectiveness and efficiency of shared equipment, personnel and technologies toward one unified plan.

Tools and Processes

For several decades members of BASES Emergency Preparedness have actively worked together to develop, test and successfully implement one common regional emergency notification and deployment system.  Members clearly define specific types of scenarios that require immediate notification into centralized dispatch services.  Modern computer-based technologies are used to quickly disperse emergency information in a highly controlled manner across the region.  As this occurs, dedicated radio channels operate in parallel to ensure real-time updating and full alignment of responder expectations.

Depending on the scenario, local and industrial response teams could be notified, put on standby or deployed as required.  Specialized equipment maintained by response teams and/or BASES Emergency Preparedness are also on standby for deployment as needed by Incident Command.  Mutual Aid Codes are used to help streamline this process.

Scenarios and Mutual Aid Codes

BASES Emergency Preparedness member companies utilize a standardized system to communicate with area Emergency Management Coordinators, Dispatch, and one another in the event of an emergency. This codified system is known as Mutual Aid Code Notifications and alerts necessary parties to the nature of an emergency event.

  • CODE 5 – Emergency without ownership
  • CODE 6 – Municipal response for community impact
  • CODE 7 – Security threat
  • CODE 8 – Internal emergency response event
  • CODE 9 – Mutual aid request
  • CODE 9-1 – Request for specific responders or equipment
  • CODE 9-2 – Request for mobilization of all response teams and equipment
  • CODE 10 – Spill to the St. Clair River requiring downriver notification

BASES Emergency Notifications to the Public

As emergency responders focus their attention on the incident, dedicated roles within our BASES member sites provide notifications to the public to establish transparency, awareness, and readiness.  All public communications regarding an emergency event are vetted through Incident Command / Unified Command to ensure accuracy of the information.  To share these updates, BASES members access the Everbridge regional notification tool.  This tool allows messages to be created and then delivered out to the public using texts, emails, recorded phone message, and posting on social media and website.  For more information on how to subscribe to receive these notifications, please visit Sarnia-Lambton Alerts.

In rare circumstances, the local municipality shall be responsible for all emergency notifications and communications where the public is required to shelter in place or evacuate in response to a natural disaster, pandemic or industrial upset.


Throughout Lambton County, an integrated notification system alerts residents in the event of an emergency event. This system uses sirens strategically located throughout the county, coordinated television interruptions, and radio broadcasting to inform the public that an emergency event has taken place and any response actions. BASES Emergency Preparedness sirens sound for nine minutes to alert the public that a non-routine industry event has taken place. Residents are asked to go indoors and tune to a local radio station for instructions. The BASES Emergency Preparedness sirens are tested every Monday at 12:30pm with the test lasting for approximately 15 seconds.

Equipment and Procedures

Mutual Aid Inventory 

BASES members own and maintain the following equipment that is readily accessible by all members of BASES Emergency Preparedness:

  • Firefighting foam inventory on a tanker truck
  • Mobile Environmental Monitoring Unit

Regional Inventory 

BASES members supply up to date lists of emergency response equipment into BASES so a combined inventory is available for review by all responders. This allows responders to make quick decisions regarding deployment of equipment to emergencies as part of the mutual aid design in Sarnia-Lambton. This inventory includes equipment required for fire, spill, rescue, security, and medical response. This open information sharing underlines the collaborative approach that transforms excellent individual response teams into one integrated team that provides world class response to any conceivable emergency scenario.
