Protocols/Shell H2S

From PCSAR

Revision as of 20:53, 16 October 2011

Background

As a result of their exercise in June 2011, Shell identified a need to work better with Pincher SAR. During an H2S incident, if they don't immediately locate a resident and have reason to believe they are still in the area, they would want a search to be initiated.

Shell and Pincher SAR subsequently negotiated a protocol where Pincher SAR will provide search management and operations. Pincher SAR will provide a SAR manager as an advisor early on in their incidents. When the need for a search is identified, Pincher SAR will be in charge of that activity. Industry personnel will accompany search teams for safety.

Profile

H2S incidents originating from commercial oil or gas field facilities, where search and rescue groups may be involved, would generally fall into three possibly scenarios:

1) an instantaneous release due to equipment failure followed by isolation of the failed equipment and a diminishing gas cloud

2) an instantaneous release due to equipment failure followed by complications in isolating the release or weather conditions that do not disperse the gas cloud quickly

3) a drilling operation were the incident may develop over several hours or days allowing for a standby situation prior to any searches

H2S events evolve relatively slowly, so that there would typically be time to conduct the search before searchers may have to be withdrawn. They expect hours or days in this phase. Typically 6 hours, occasionally as low as 2 hours.

There would typically be only one individual or party being searched for. The search areas might be up to 3 quarter sections of open agricultural, forested, or mountainous terrain. The subjects would be responsive (no expectation of simultaneous injury). Helicopter, vehicle, quad and foot teams would be used.

During an evolving event, Shell would has different levels of activation:

• Alert: Shell has received information about a possible incident but has not confirmed it.
• Level 1: An incident has been confirmed, but is not at the level to require evacuations. Public in the area will be notified. Any person suspected to be in the area, but not found for notification, would potentially be a search subject at Level 2.
• Level 2: Non-workers in the area will be required to evacuate. A search is conducted for public that are suspected to still be in the area.

Shell typically co-locates the Incident Command Post with the Emergency Operations Centre at the Shell Waterton Plant.

Protocol

Policies:

1. SAR responders will only be working in H2S environments where it is possible to work safely without masks.
2. An experienced industry safety person will accompany all SAR teams and be constantly monitoring the environment.
3. As in any incident, SAR workers will not be encouraged to work in an environment where they don't feel comfortable.
4. When participating in a search, Pincher SAR will be responsible for directing and performing the search operations; Shell will be responsible for the safety of the field teams.
5. Costs of the SAR response will be paid for by Shell.

Procedure:

1. Upon reaching Level 1 or higher, Shell's Logistics Section will contact Pincher SAR and request a Search Manager attend the Incident Command Post.
   • Rationale: Go big fast. Don't know whether SAR will be required but better to get involved early.
   • Contact: 403-627-2262 (Dispatch through STARS Link Centre) or 403-627-5804 (On-call Manager)
   • Note: Shell might chose to add 403-627-5804 to their automated notification system and call 403-627-2262 only if there is no answer on the first number. The STARS Link Centre is not a suitable number to receive an automated call.
2. The Pincher SAR Manager will evaluate the situation and determine whether it is appropriate for Pincher SAR to be involved.
   • If the situation matches the above profile, it normally would be appropriate
3. The Pincher SAR Manager contacts the tasking agency (Pincher Creek RCMP) and recommends that Pincher SAR be tasked to respond at the level of a SAR Manager involvement.
   • Note: Shell will already have notified the RCMP at a Level 1
   • Rationale: This will provide liability and WCB coverage.
4. The RCMP member tasks Pincher SAR to respond.
5. The PCSAR Manager puts a PCSAR Call-Out Person on stand-by.
6. The PCSAR Manager attends the Incident Command Post and assumes the ICS role of Technical Advisor on SAR.
7. The PCSAR Manager maintains an awareness of the efforts to notify the public at Level 1 (rovers) and if appropriate in the evolving situation, has PCSAR members put on stand-by.
8. If the incident goes to Level 2, Shell Incident Commander appoints the PCSAR Manager to the additional ICS role of "Evacuation/Search Leader". From that role, The PCSAR Manager directs the search effort.
9. A full activation of PCSAR members is undertaken
   • Note: Members arrive typically in 45 minutes + travel time. Possible use of Shell's automated call-out system can reduce this time.
10. When the subjects are found and evacuated or it is unsafe to be in the area, PCSAR members are withdrawn.
11. The PCSAR Manager remains in the role of Technical Advisor until the incident drops below Level 1.
    • Rationale: additional searches may evolve

Support

Training

Training would be provided to SAR volunteers on working safely in an H2S environment. This would be to raise the confidence of SAR volunteers that they can be safe in such environments.

Shell Incident Commanders will receive an orientation on the basics of what SAR can provide, what SAR needs, and how to work with SAR.

Shell rovers will receive training on

• the do's and don't's of search prior to trained SAR workers showing up
• e.g. how to avoid damage tracking information at vehicles

The industry safety personnel that will accompany SAR teams will receive training on

• how to work with trained SAR personnel.
  • roles and responsibilities
• purposeful wandering

A mock incident will be set up to validate this protocol.

Notification System

To further reduce our time to scene, Shell is offering the use of their automated call out system to notify our members.

Use #1: to notify the on-call manager when a Level 1 is reached.

Use #2: to notify all SAR responders for a standby or call-out

Radio Channel

Shell's 2 field radio channels have been added to PCSAR's radios to aid intercommunications.

To do

(review: Brett Wuth)

• confirm protocol with RCMP
• Label Shell's channels on PCSAR radios
• review Shell's automated calling system with Shell or their provider
• provide H2S training to members
• Notify SARA / BC that may be model for other areas (after approved)
