A
Reminder...
The
month of May marks the fourth anniversary of the ValuJet tragedy in the
Florida Everglades. 110 persons lost their lives because the carrier failed
to follow correct procedures for the identification, packing, marking,
labeling, and documentation of dangerous goods and the company failed
to train its employees and its agents (subcontractors) in the proper handling
of dangerous goods.
As trainers and packers
of dangerous goods we witness carelessness, indifference, and a scary
amount of thoughtlessness or a total lack of knowledge when dealing with
(or avoiding) dangerous goods.
Chemical oxygen generators,
classed as oxidizers, caused the ValuJet accident. Due to a lack of awareness
the generators were improperly packaged and during the takeoff the apparently
improperly stowed and secured boxes were damaged by other cargo causing
a rapidly expanding chemical reaction that resulted in an extraordinarily
hot fire that caused the crash within about 10 minutes after the take
off. The temperatures are said to have exceeded 2500 degrees F. No one
involved in the handling or loading of those generators wanted to cause
those 110 violent deaths.
If you are involved
in any way with the transportation of cargo, either as a passenger, shipper,
trucker, freight forwarder, or carrier, we would urge you give some thought
to what it must have been like to embark on a trip home, or to a meeting
with a business acquaintance. In the space of a painful 10 minutes or
less you have no other air to breathe but the smoke and furnace-like air
from a raging 2500 degree fire. Employees who did not know anything about
dangerous goods caused those final minutes of agony and death. Not on
purpose, though. They just didn't know any better!
When you go on your
next trip, or your family is going on vacation, give some thought about
the freight compartment below you. Was the cargo examined carefully to
determine if dangerous cargo was present? If dangerous cargo is present,
was it packaged and identified correctly? Is the flight crew aware of
its presence? Did the shipper identify it correctly to begin with? Or
is the shipper trying to avoid the extra charges for dangerous goods?
Maybe, like the Sabertech employees working for ValuJet, the shipper or
forwarder or carrier personnel don't know any better either.
Oxidizers are chemicals
that, when involved in a fire, release oxygen, causing a greater intensity
of the fire or are capable of reacting with other chemicals, causing a
fire or explosion. ValuJet taught us just how "intense" that
fire can get.

Other
important issues for May 2000.
Oxidizing
powders can also cause dust explosions.
Typical oxidizing
chemicals are pool chemicals, water treatment chemicals, raw materials
for drugs and pharmaceuticals, ingredients in bakery products and cereals,
powdered bleaching agents, fertilizers, and frequently the ingredients
in explosives. But, don't forget, oxygen, which is a non-flammable gas
(division 2.2), has a secondary hazard of being an oxidizer. Oxidizing
Substances usually require a diamond-shaped yellow label with the symbol
of a fire on the top half and the number 5.1 in the bottom corner.
Observation: when
a fire inspector comes on your property, one of the first things the inspector
wants to know is whether or not you store oxidizers in the building. Your
insurance company is equally concerned. Are you?
Oxygen Generators
And, finally, the
U.S. Department of Transportation requires that chemical oxygen generators
cannot be shipped without a Competent Authority Approval. This applies
to imports and exports as well as domestic shipments. Make sure the packages
have not been compromised and read the approval carefully. Some approvals
allow for surface shipment only!
