Released on June 11, 1999
Saskatchewan's Deputy Chief Medical Health Officer, Dr. Eric Young,
today issued a public health notice regarding hydrogen
sulfide-contaminated propane that was delivered to consumer
distribution outlets in central Alberta between May 29 and June 9,
1999.
"Officials have indicated that none of the contaminated product has
been distributed to retail outlets in Saskatchewan," Dr. Young said.
"However we are advising Saskatchewan travellers who have visited
Alberta and may have purchased contaminated propane from the service
outlets listed below, between May 29th and June 10th, 1999, not to use
it, to leave the container closed and ensure proper disposal."
Individuals needing information regarding disposal of propane that may
be contaminated are advised to contact Western Facilities Management
Limited at 1-800-665-5896.
"It is important that people not try to sniff their propane tanks to
see if they are contaminated," Dr. Young said. "You can't smell the
gas at this high level of concentration and inhaling it could result
in respiratory paralysis."
Alberta retail propane outlets identified so far that received
the contaminated propane include:
Castor Esso Blackfalds Gas and Wash
Ponoka Shell Sylvan Lake GTI (Eckville)
Ponoka UFA Bashaw UFA
Lacombe PetroCanada Zig Zag Deerpark CO-OP (Red Deer)
Stettler Bagshaw Morningside Fuel Service
Stettler UFA Delburne UFA
Linden CO-OP Innisfail CO-OP
Tracks Shell (Sundre) Red Deer FasGas (south)
Ponoka CO-OP
"Although hydrogen sulfide itself is highly toxic, in this
particular situation, the gas is contained," Dr. Young said.
"Therefore, the likelihood of any appreciable exposure is
limited. Any problems that are likely to arise could occur when
customers and filling station attendants are exposed to stray
emissions when refuelling vehicles or barbecue propane bottles,
or when lighting a propane barbecue."
The contaminated propane is believed to contain very high and
hazardous concentrations between 400 and 1,000 parts per million
(ppm) of hydrogen sulfide. Hydrogen sulfide is a colourless gas
that can be dangerous to humans when inhaled and when it comes
into contact with the skin or mucous membranes.
"Low-level exposure, as is most likely in this particular
situation, can cause eye pain and redness with blurred vision, as
well as irritation of the upper respiratory tract and the lungs.
Nausea, dizziness and confusion are also possible effects.
Exposure to high levels of hydrogen sulfide can cause immediate
death," Dr. Young said.
