Dot hazardous material identification numbers

For example:. The next piece of information you should look for is a number in the bottom corner of the diamond. This number refers to the hazard classes used by the United States Department of Transportation DOT , as well as those used internationally. These hazard classes are:. Next, look for a symbol in the upper corner. Placards can feature a variety of different symbols to warn of the possibility of an explosion, combustion, destruction of materials and skin by corrosives, radiation, oxidizers, compressed gas, or poison.

The last piece of information made readily available by these placards can come in two forms: a four-digit United Nations UN number used to describe the hazardous material such as for acetylene or, more simply, the name of the substance. Hazardous material placards seem incomprehensible at first glance — nothing more than a jumbled mix of symbols, colors, patterns and numbers.

The basic marking requirement consists of the proper shipping name and identification number of the hazardous materials contained in the package. Markings should be durable, in English, and not obscured by other markings or labels.

Depending on the material there may be additional marking requirements. For non-bulk packaging, technical names must be marked in parenthesis in association with the proper shipping name if required by Identification numbers are not required for ORM-D and limited quantities. Bulk packaging requirements are in section Identification Numbers must be on each side and each end for packages L 1, gals or more and for cylinders permanently mounted on tube trailer motor vehicles.

Identification Numbers on two opposing sides for packages less than L 1, gals. Technical names are not required for bulk packages.

For complete definition of hazmat employer and hazmat employee please see definitions contained in appendix A. All hazmat employees must have this training. Function-specific training: Function specific training is intended to teach the necessary knowledge, skills and abilities for an individual's job function. Safety training: This training provides information concerning the hazards posed by materials in the workplace and personal protection measures.

    The training may include basic emergency response procedures but is not intended to satisfy the requirements of 29 CFR Security Training: Each hazmat employee must receive security awareness training. This training must include an awareness of security risks associated with hazardous materials transportation and methods designed to enhance transportation security. After March 25, , hazmat employees must receive this training at their next scheduled recurrent training, but in no case later than March 24, New hazmat employees must receive this training within 90 days of employment.

    In addition to the above security awareness training, hazmat employees of employers that are required to have a security plan must receive in-depth security training on the security plan and its implementation. The regulation does not specify sources of training. It is the hazmat employer's responsibility to determine the adequacy of the training being presented. Training may be in any appropriate format including lecture, conference, self paced instruction, interactive video, etc.

    A new hazmat employee who changes job functions may perform those functions prior to completion of training, provided the employee performs those functions under the direct supervision of a properly trained and knowledgeable hazmat employee; and the training is completed within 90 days after employment or job function. Employees must receive the required training every three years or any time there is a change in job function.

    The international standards have general requirements for materials, construction and a maximum capacity as compared to detailed DOT specifications for non-bulk packagings formerly contained in 49 CFR, Part Packaging requirements are based on the Packing Group of the material, its vapor pressure, and chemical compatibility between the package and the HM. Non-bulk packaging standards are based upon a number of performance tests. In addition to UN Recommendation performance oriented tests, a vibration test for non-bulk packaging is required domestically.

    Reuse of plastic and metal is drums based on minimum thickness requirements. This substitutes for the lack of performance tests in UN standards with regard to puncture resistance, abrasion resistance and metal fatigue. Package manufacturers must provide written notification to customers of any specification shortfalls or steps to be taken to conform with applicable specification.

    Performance tests for UN packaging, including design qualification tests and periodic retests, are included in Part The packing group designated in the The shipper is responsible for determining the appropriate packing group. If more than one packing group is indicated for an entry, the packing group for the HM is determined using the criteria in 49 CFR, Part , Subpart D.

The following additional markings are required:. Part for highway contains a number of general and specific requirements for loading and unloading hazardous materials in Hazardous materials packages should be secured in a transport vehicle to prevent damage during transportation. The motor carrier is responsible for blocking and bracing HM for shipment by highway. Therefore a carrier who removes and or alters blocking and bracing material installed by the shipper is not necessarily in violation of federal law.

    If the hazardous materials leaks or spills during transport due to insufficient blocking and bracing, the motor carrier is at fault. Both shippers and carriers are responsible for compatibility. The requirement for shippers to comply with compatibility considerations is contained in 49 CFR
