SAFETY-RELATED
NON-FLAMMABLE
The unique formulation of PennzSuppress®
D utilizes water as a dilutent, and contains no flammable components. Because
the emulsified resin contains water, it is basically “self-extinguishing”
in its concentrated form. In use, the product is diluted with more water for
the purpose of application, which serves to further reduce any concerns over
flammability. PennzSuppress®
D is not classified as flammable, or combustible, and therefore is not
regulated by the U.S. Department of Transportation (DOT) during
transportation, nor does the National Fire Protection Association (NFPA)
recommend specific conditions for its storage or use.
NON-CORROSIVE TO METAL
There is often a concern about possible damage to vehicles and equipment
operated on roads that have been treated with dust suppressants. To evaluate
the corrosivity, or potential corrosivity of a dust suppressant toward metal,
corrosion rate tests can be conducted. When tested as a concentrate in the
presence of carbon steel, PennzSuppress®
D yields a corrosion rate of 3.5 mm/year, which indicates very low corrosive
tendencies. When diluted for actual use on a road, the corrosion rate
would be even lower. Magnesium chloride and calcium chloride, both of which
have been used for many years as road dust suppressants, yield far greater
corrosion rates to carbon steel, and have been known to cause metal pitting
and stress cracking, with prolonged exposure. The DOT classifies materials
with corrosion rates of <6.5 mm/year as non-corrosive. When PennzSuppress®
D is used to treat roads and dusty areas, premature corrosion of vehicles and
equipment need not be a concern.
