Dear Mr. Mazzullo:
I am writing to request written DOT confirmation that we are correct in shipping
use by field service technicians in the repair and maintenance of refrigeration
equipment.
"RX-11" is an Aerosol, Class 2.2, UN1950 under the Hazardous Materials
Regulation (49 CFR Parts 171-180), with the following technical details:
1. Packaging: Metal, DOT 2Q specification aerosol can, filled in compliance
with all conditions listed in 173.306(a)(3). Filled containers are packaged
and sealed in outside packaging consisting of either a 200# test corrugated
fiberboard carton, or a heavy duty combination corrugated
fiberboard/thermal shrink plastic film.
2. Propellant: Non flammable liquid propellant.
3. Active Ingredient: The active ingredient is a non flammable cleaning
solvent, that when not packaged in an aerosol can, is classified as a non
hazardous, non regulated, liquid cleaning compound.
Although we are confident that the "RX-11" package meets the definition of
Consumer Commodity ORM-D as defined in 171.8 and provided in 173.306(a)(3) and
professional refrigeration service technicians. This distinction has our shipping
173.306(h), it will be distributed and sold for consumption by individuals trained as
people requesting written D.O.T. confirmation that the "RX-11" qualifies for shipment
as a "Consumer Commodity, ORM-D".
