TITLE>Toxic Waste Drum ManufactureThe following describes the drum composition that will be used during the 1996 and 1997 International Aerial Robotics Competition at EPCOT; this should be of general interest to all competitors

For those of you that can decode manufacturer's markings on plastic drums, I will provide the information found on the bottom of the drums that will be used in the 1996 International Aerial Robotics Competition. These were donated by a local Atlanta company that receives a type of fungicide in them.

The markings on the bottom of the drums is as follows (there are no other markings other than the contents labels which are paper and have been removed):

2                       (surrounded by circulating arrows;
                         probably indicating the nature of
                         the recycling process to be used
                         with these drums)

HDPE                    (high density polyethylene)
5-10HLM1

M4766
8/95                    (date of manufacture)

UN/1H1W/Y1.9/190/95     (drum specification)
USA/+AA0821             (drum specification)
2.2MM

The drum material is believed to be polyethylene (black) and the drum style is similar to Delcon closed-head type 74101 55 gallon containers. Drums are blow molded. Closed head drum has one 2-inch NPT plug and one 2-inch buttress and accommodates standard filling and emptying devices. Designed to be used with foods, corrosives, acids, cleaners, hazardouste waste, pharmaceuticals, photo chemicals, class B poisons, bleaching chemicals, but not for fuels or oils.
