Consumer Products

It seemed such a simple task at the time. A company decided to expand their consumer product line to include perfumes. They expected to send orders to customers, as they did their other products, by airmail. Yet, when setting up the shipment, an unexpected roadblock appeared. The U.S. Postal Service (USPS) told them that the perfume was a hazardous material.

How can a common consumer product like perfume be hazardous for transportation? Most perfumes have an alcohol base, designed to evaporate quickly leaving the scent behind. Unfortunately, this means that such perfumes are flammable liquids for transportation and are subject to Department of Transportation (DOT) as well as USPS restrictions for both ground and air transport.

So, the decision to go into perfumes created some major headaches for the company. But they recently got some good news. If the perfume is based on ethanol, one of the most common alcohols, the company will get a break – USPS has reduced the requirements for this one solvent. Ethanol, or ethyl alcohol, can be found in many consumer products, ranging from perfumes to hairspray to bath oil. By reducing the requirements for shipment of these products, shippers will enjoy reduced costs and complexity.

Airmailing Hazardous Materials

If you wish to airmail hazardous materials in the United States, your first step should be to consult USPS Publication 52 – Hazardous, Restricted, and Perishable Mail. Continue Reading…

Gasoline mixtures

Transport Canada has posted a Bulletin to their website on ethanol and gasoline mixtures.

For shippers, the classifications to be used are as follows:

  • for mixtures up to 10% ethanol (E10): gasoline, UN1203
  • more than 10% but less than 100% (> E10 < E100); ethanol and gasoline mixture, UN3475
  • 100% ethanol (E100): ethanol or ethyl alcohol, UN1170

Ethanol and gasoline mixtures must not be classified as:

  • UN1987, ALCOLHOLS, N.O.S.,
  • UN1993, FLAMMABLE LIQUIDS, N.O.S, or
  • NA1987, DENATURED ALCOHOL

For emergency responders, the different blends mean different responses in the event of fire. For mixtures up to E10 (UN1203), emergency responders can use the aqueous film forming foam (AFFF) that is usually used to combat gasoline fires.

However, for mixtures in excess of E10 (UN3475 and UN1170), the use of AFFF is virtually useless as these mixtures are polar/water-miscible flammable liquids that degrade the AFFF. Emergency responders should be using AF-AFFF (alcohol resistant, aqueous film-forming foam).
