Product Description

Shipping labels are essential for packages that contain dangerous goods. These D.O.T. shipping labels are designed to meet and comply with regulations and specifications under Title 49, Subtitle B, Chapter I, Subchapter C, Part 172 of the CFR.

Printed with fade resistant ink, these labels are available in paper for indoor applications and vinyl for extended outdoor use. The labels measure 4" x 4" and are sold 500/roll. For corresponding vehicle placards see item #03110.

TECHNICAL NOTE 1: The US Department of Transportation's DOT Chart 15, Hazardous Materials Markings, Labeling and Placarding Guide is a terrific full-color compliance guide for placarding and labeling and is available for download from their web site.

TECHNICAL NOTE 2: In paragraph (b) of 49 CFR 173.124,  a Spontaneously Combustible Material (DOT Division 4.2) is

  1. A pyrophoric material is a liquid or solid that, even in small quantities and without an external ignition source, can ignite within five (5) minutes after coming in contact with air when tested according to UN Manual of Tests and Criteria.
  2. A self-heating material is a material that through a process where the gradual reaction of that substance with oxygen (in air) generates heat. If the rate of heat production exceeds the rate of heat loss, then the temperature of the substance will rise which, after an induction time, may lead to self-ignition and combustion. A material of this type which exhibits spontaneous ignition or if the temperature of the sample exceeds 200 °C (392 °F) during the 24-hour test period when tested in accordance with UN Manual of Tests and Criteria (IBR; see § 171.7 of this subchapter), is classed as a Division 4.2 material.

See the SDS HyperGlossary entry on flammable solids as well as pyrophoric for examples and additional reading on these potentially hazardous substances.
