Premier Christy Clark: LNG is safe when released to the Atmosphere; However the Ammonia Refrigerant Incidents say othewise

Seven out of Twelve Incidents: Ammonia

Premier Christy Clark and Energy Minister Bill Bennett invites British Columbians to Explore their LNG projects

2016



Imagine this as the New and Improved LNG Plant - Tilbury Island on the Fraser River, or any of the other 18 projects  or TEN approved NEB or 33 project partners of LNG might want to ship their products off the shores of British Columbia.  

eg. Low Cost - High Efficiency and Low Emissions

BC Hydro electricity will be supplied for a pittance, or free, from Site C, as the means to super cool the LNG so that it can be transported to the Ports in refrigerated rail tanker cars eg. CNR and CPR, and if luck was on our side it would have included money losing BC Rail.

Leader Christy Clark has been raving about the safety aspect of transporting LNG on the basis that if there was a leak on land or at sea, the LNG would just evaporate into the atmosphere.  No harm done.

As it turns out there's an arm of government called the British Columbia Safety Authority which has an annual duty to state where we are when it comes to the:

 State of Safety Reports

One of the Safety Authority's specialties is dealing with past incidents involving passengers tripping off of platforms or falling on escalators, sudden lurching to a STOP with a gash to the forehead.  There's also a large section on Ammonia, a refrigerant, the one that LNG needs, to be kept super cooled.  The report for 2014 is for data between 2007 and 2013, in other words prior to the boom of 2016 LNG shipment start-ups.

The Safety Authority provides a backgrounder to incidents on many fronts but also on Ammonia:

Lower Mainland (A2-4); Northern Vancouver Island (A2-5); Okanagan Valley (A2-6); Central-Northern BC (A2-7)

The three years prior to 2007 there wasn't any Ammonia Incidents to report.

 Hazards of Ammonia

1. Exposure to more than 2,000 ppm – fatal in 30 minutes, 6,000 ppm – fatal in minutes, 10,000 ppm – fatal and intolerable to unprotected skin.

2. Anhydrous Ammonia is not dangerous when handled properly, but if not handled carefully it can be extremely dangerous. It is not as combustible as many other products that we use and handle every day. However, concentrations of gas burn and require precautions to avoid fires.

3. Mild exposure can cause irritation to eye, nose and lung tissues. Prolonged breathing can cause suffocation. When large amounts are inhaled, the throat swells shut and victims suffocate. Exposure to vapours or liquid also can cause blindness

.. presume Ms Christy Clark has never heard of a
BLEVE (boiling liquid expanding vapor explosion)
She will someday.. hopefully not at an LNG terminal
on the BC coast, or aboard an LNG supertanker

A reporter thought horseshoe bay closing debate maybe was due to future LNG proximity shipping path?squamish

North Van's Grumps said...

A more plausible reason for closing Horseshoe Bay would be the cost of maintaining BC Ferries link to Langdale when a highway route between Squamish and via the LNG plant to Langdale / Gibson / Sechelt and all points west.

What s BC to do to offset the forest fire carbon offset?
lower BC speed limit ,sell less LNG or coal?
