D.O.T. Flammable Liquid Label for Hazardous Materials

Packing Group I, if they have an initial boiling point of 35°C or less at an absolute pressure of 101.3 kPa and any flash point, such as diethyl ether or carbon disulfide. Very often used for fumigation in airtight storage warehouses, airtight flat storages, bins, grain elevators, railroad box cars, shipholds, barges and cereal mills. Carbon disulfide is used as an insecticide for the fumigation of grains, nursery stock, in fresh fruit conservation and as a soil disinfectant against insects and nematodes. Carbon disulfide is a solvent for phosphorus, sulfur, selenium, bromine, iodine, fats, resins and rubber. The principal industrial uses of carbon disulfide are the manufacture of viscose rayon, cellophane film, carbon tetrachloride and xanthogenates and electronic vacuum tube. It is also used in the manufacture of Bamboo Fiber.

Diethyl ether is prone to peroxide formation, and can form explosive diethyl ether peroxide. Ether peroxides are higher boiling and are contact explosives when dry. Diethyl ether is typically supplied with trace amounts of the antioxidant BHT (2,6-di-tert-butyl-4-methylphenol), which reduces the formation of peroxides. Storage over NaOH precipitates the intermediate ether hydroperoxides. Water and peroxides can be removed by either distillation from sodium and benzophenone, or by passing through a column of activated alumina.[15]

Ether is extremely flammable. The autoignition temperature of ether is only 170 °C (338°F), so it can be ignited by a hot surface without a flame or spark. A common practice in chemical labs is to use steam (thus limiting the temperature to 100 °C (212 °F) when ether must be heated or distilled. The diffusion of diethyl ether in air is 0.918·10−5 m2/s (298K 101.325 kPa).

Labeling  ( Reference from http://www.fmcsa.dot.gov )

§ 172.407Label specifications.

(a) Durability. Each label, whether printed on or affixed to a package, must be durable and weather resistant. A label on a package must be able to withstand, without deterioration or a substantial change in color, a 30-day exposure to conditions incident to transportation that reasonably could be expected to be encountered by the labeled package. 

(b) Design.

(1) Except for size and color, the printing, inner border, and symbol on each label must be as shown as appropriate.

 (2) The dotted line border shown on each label is not part of the label specification, except when used as an alternative for the solid line outer border to meet the requirements.

 (c) Size.

(1) Each diamond (square-on-point) label prescribed in this subpart must be at least 100 mm (3.9 inches) on each side with each side having a solid line inner border 5.0 to 6.3 mm (0.2 to 0.25 inches) from the edge. 

(2) The CARGO AIRCRAFT ONLY label must be a rectangle measuring at least 110 mm (4.3 inches) in height by 120 mm (4.7 inches) in width. The words “CARGO AIRCRAFT ONLY” must be shown in letters measuring at least 6.3 mm (0.25 inches) in height. 

(3) Except as otherwise provided in this subpart, the hazard class number, or division number, as appropriate, must be at least 6.3 mm (0.25 inches) and not greater than 12.7 mm (0.5 inches). 

(4) When text indicating a hazard is displayed on a label, the label name must be shown in letters measuring at least 7.6 mm (0.3 inches) in height. For SPONTANEOUSLY COMBUSTIBLE or DANGEROUS WHEN WET labels, the words “Spontaneously” and “When Wet” must be shown in letters measuring at least 5.1 mm (0.2 inches) in height. 

(5) The symbol on each label must be proportionate in size to that shown in the appropriate section of this subpart.

(d) Color.

(1) The background color on each label must be as prescribed as appropriate. 

(2) The symbol, text, numbers, and border must be shown in black on a label except that— 

(i) White may be used on a label with a one color background of green, red or blue. 

(ii) White must be used for the text and class number for the CORROSIVE label. 

(iii) White may be used for the symbol for the ORGANIC PEROXIDE label. 

(3) Black and any color on a label must be able to withstand, without substantial change, a 72-hour fadeometer test (for a description of equipment designed for this purpose, see ASTM G 23-69 (1975) or ASTM G 26-70). 

(4) (i) A color on a label, upon visual examination, must fall within the color tolerances— 

(A) Displayed on color charts conforming to the technical specifications for charts set forth in table 1 or 2 in appendix A to this part; or 

(B) For labels printed on packaging surfaces, specified in table 3 in appendix A to this part.

 (ii) Color charts conforming to appendix A to this part are on display in Office of Hazardous Materials Safety, Office of Hazardous Materials Standards, Room 8422, Nassif Building, 400 Seventh Street, SW., Washington DC 20590–0001. 

(5) The following color standards in the PANTONE ® formula guide coated/uncoated may be used to achieve the required colors on markings and hazard warning labels and placards: 

(i) For Red—Use PANTONE ® 186 U 

(ii) For Orange—Use PANTONE ® 151 U 

(iii) For Yellow—Use PANTONE ® 109 U 

 (iv) For Green—Use PANTONE ® 335 U

 (v) For Blue—Use PANTONE ® 285 U 

(vi) For Purple—Use PANTONE ® 259 U 

(6) Where specific colors from the PANTONE MATCHING SYSTEM®are applied as opaque coatings, such as paint, enamel, or plastic, or where labels are printed directly on the surface of a packaging, a spectrophotometer or other instrumentation must be used to ensure a proper match with the color standards in the PANTONE® formula guide coated/uncoated for colors prescribed in paragraph (d) (5) of this section. PANTONE®is the property of Pantone, Inc.

 (7) The specified label color must extend to the edge of the label in the area designated on each label, except for the CORROSIVE, RADIOACTIVE YELLOW-II, and RADIOACTIVE YELLOW-III labels on which the color must extend only to the inner border. 

(e) Form identification. A label may contain form identification information, including the name of its maker, provided that information is printed outside the solid line inner border in no larger than 10-point type. 

(f) Exceptions. Except for materials poisonous by inhalation a label conforming to specifications in the UN Recommendations may be used in place of a corresponding label that conforms to the requirements of this subpart. 

(g) Trefoil symbol. The trefoil symbol on the RADIOACTIVE WHITE-I, RADIOACTIVE YELLOW-II, and RADIOACTIVE YELLOW-III labels must meet the appropriate specifications in appendix B of this part.
