Fires are a major cause
of death and injuries. It is estimated that 4,300 persons are killed
in the United States each year and 27,000 are injured. For the European
Union the estimates are over 4,000 killed and 80,000 injuries per
year. Many products are made safer through the appropriate use of
flame retardants but still more could be done to improve fire safety
further.
Fires happen
when a combustible material comes in contact with a potential ignition
source. The role of flame retardants is to make materials harder
to ignite, and if once ignited, in many cases to reduce the rate
of heat release or the rate at which flames spread to limit the
total quantity of material involved in a fire.
In most cases
fire test specifications are set with small scale test methods such
as the UL 94 test from Underwriters Laboratories and these are usually
the tests used by flame retardant manufacturers to demonstrate the
effectiveness of their products. However the scale of these test
methods is a lot different to the real fires which kill and maim
real people. The real test of the effectiveness of flame retardants
is therefore in the difference they make in preventing actual fires.
Obviously
it is impossible to count 'fires that don't happen'. Fortunately
however there are a number of areas where actual fire statistics
can demonstrate the clear benefits in saving lives and property
through the use of fire test standards that require the use of flame
retardants. Here are some examples:
Television
Sets
The
anti-halogen stance of some environmental organizations in Europe
led to a consumer test magazine in Germany (1) downgrading those
TV sets which contained brominated flame retardants. This encouraged
TV manufacturers in the European Union to phase out the use of flame
retardants in the cabinets since they were not actually required
to meet the safety requirements in IEC 65 (2) . This states that
enclosure materials should meet the requirements of the HB (Horizontal
Burning) classification. The result of this change was that the
number of TV set fires in Europe , which had been steadily decreasing
over a number of years, began to increase again (3).
Upholstered
Furniture
The
state of California has had its own fire test regulations (4) for
upholstered furniture since 1975. Statistics (5) demonstrate that
the number of furniture related fire deaths in this state is significantly
lower than in the remainder of the United States .

In the United
Kingdom a new furniture fire safety regulation was introduced in
1988 to reduce the flammability of furnishing fabrics and fillings.
A recent UK Government Report (6) reviewed the effectiveness of
these Regulations after 10 years in operation. It estimates that
the increased escape time due to ignition resistance and post ignition
fire behavior of furniture to have saved 1860 lives between 1988
and 1997 and prevented at least 5,770 injuries. The effectiveness
of this Regulation is expected to increase still further as pre-1988
furniture is progressively replaced.
Coal
Mining
Coal
mines have always been dangerous places with risks of fires and
explosions. Conveyor belts are a major hazard because of their potential
to generate an ignition source and to spread a subsequent fire.
The most frequent danger arises from damaged idler rollers jamming.
The resultant friction of the belt moving over them can generate
sufficient heat to ignite spillage and dust nearby (7) . In the
United Kingdom this type of fire occurrence led to regular deaths
culminating in a major disaster at Cresswell Colliery in September
1950 when 80 miners died. This resulted in the introduction of the
NCB 158 (later incorporated in BS 3289) fire test and the use of
flame retarded PVC conveyor belting. Since then, although many similar
fire situations have arisen, no conveyor belt meeting these specifications
has ignited or spread a fire in a United Kingdom coal mine.
These are just
three examples, from widely differing industries and applications,
which demonstrate how flame retardants have been effective at saving
lives and making the world we live in a safer place.
Flame
Retardants
Flame Retardants
are an important but not the only means of improving fire safety.
In practice a balanced approach to fire safety is required including:
The selection and use of non-combustible materials or materials
which are less likely to ignite and propagate fire
The treatment of potentially flammable materials to make them
more difficult to ignite and spread fire
The safe design and construction of buildings
The installation of smoke detectors, fire alarms, and sprinkler
systems

fire safety and making the world a safer place. Visit these web

Great
Lakes manufactures a wide range of flame retardants based on different
technologies. Flame retardants are incorporated into certain materials
and applications to reduce the likelihood of accidental ignition
and development of a fire thereby reducing damage to property and
the risks of injury or death. When manufactured and utilized properly,
flame retardants pose no threat to human health. Government commissioned
studies have shown that the benefits of using flame retardants outweigh
any risks (see reference: Risks and Benefits in the Use of Flame
Retardants in Consumer Products )
Two of the
major classes of flame retardants manufactured by Great Lakes are
based on bromine and phosphorus. Both are naturally occurring in
the environment in combination with a myriad of organic and inorganic
elements. They are found in plants, edible foods, and animal tissues
including DNA and blood.
Bromine products,
if manufactured and use properly, pose no threat to human health.
Great Lakes is a manufacturer of brominated compounds used in a
number of industries that help to promote and preserve human life
such as the pharmaceutical and flame retardant industries. Due to
the complexity and expense associated with handling elemental bromine,
brominated compounds are manufactured in a only a few very specialized
facilities around the world.
If you would like more
information on bromine and its derivatives, including flame retardants,
