MANY ISLANDS PIPE LINES (CANADA) LIMITED EMERGENCY PROCEDURES MANUAL Public Protection Methods
3.2 Public Protection Methods
Four methods are used to safeguard the public against exposure to potentially dangerous situations:
1. Shelter-in-Place
2. Evacuation
3. Ignition
4. Isolation
For the purposes of this EPM, the term public means:
Residents, transients, other industrial operators and any other people that may be impacted by an event at a company operation including workers not presently on shift and non-essential personnel who are not dealing directly with a response to an incident.
3.2.1 Planning and Response Zones
Emergency Planning Zone (EPZ)
• A geographical area surrounding a well, pipeline, or facility containing hazardous product that requires specific emergency response planning by the licensee.
North American - Emergency Response Guidebook
The 2024 Emergency Response Guidebook (ERG2024) was developed jointly by Canada, the U.S., Mexico and Argentina for use by fire fighters, police and other emergency services personnel who may be the first to arrive at a dangerous goods incident. Within the 2024 Emergency Response Guidebook under the Protective Actions section, first responders are to: • Direct all persons to move, in a direction perpendicular to the wind direction (crosswind direction), away from the spill or release to the distance specified for the Initial Isolation Zone. • Look up the initial Protective Action Distance in the 2024 Emergency Response Guidebook for a given material, spill or release size; determine whether it is day or night; identify the downwind distance and determine the most appropriate protective actions to consider.
During a response, First R esponders are instructed to block off access to MIPL’s high pressure transmission lines a minimum of a 1.61 km radius. EPZs for each gas line can be found here: MIPL System Maps
3.2.2 Air Monitoring When required, the atmosphere is monitored with sensitive equipment to track and record the presence and concentrations of hazardous air emissions during normal operations (proactive), during an incident and ongoing during a response.
The information generated from air monitoring is used to:
Track the plume
•
• Determine if ignition criteria are met • Determine if evacuation and/or sheltering criteria have been met • Determine concentrations in areas being evacuated • Determine if areas considered for evacuation are safe to do so • Identify roadblock locations
