A hazardous material is a substance (gas, liquid, or solid) capable of causing harm to people, property, and the environment. The LF.S. Department of Transportation (DOT) uses the term hazardous materials to cover nine categories identified by the United Nations Hazard Class Number System, including  

Class lA—Flash point below 73°F, boiling point below 100°F Class IB— Flash point below 73°F, boiling point at or above 100°F Class IC— Flash point at or above 73°F, but below 100°F 

Class II—Flash point at or above 100°F, but below 140°F Class IIIA—Flash point at or above 140°F, but below 200°F Class IIIB—Flash point at or above 200°F 

A general rule of thumb states that any hazardous substance that is spilled or released into the environment is no longer classified as a hazardous substance but as a hazardous waste. The USEPA uses the same definition for 

Hazardous wastes are organized by the USEPA into three categories nonspecific source wastes, specific source wastes, and commercial chemical products. All listed wastes are presumed to be hazardous, regardless of their concentrations. USEPA developed these lists by examining different types of wastes and chemical products to determine whether they met any of the following criteria

Each part of the regulation is divided into Subparts, which are identified by letters. The Subparts for 29 CFR 1910 are shown in Table 2.5. Process safety is 29 CFR 1910 Subpart H— Hazardous Materials.

Combustion is a technology employed to burn hazardous waste for energy or materials recovery. This occurs in a group of units collectively known as BIFs. The following sections will provide an overview of the regulation of these units, found in 40 CFR Part 266, Subpart H.5 21... 

Portable tanks, drums, or bottles are shipped by rail, ship, air, or truck. Portable tanks containing hazardous materials must conform to DOT regulations, Parts 173 and 178, Subpart H. 

The laboratory also may be required to report to the ERA its radionuclide quantities or to monitor airborne emission from operating stacks and by other discharges under the National Emission Standards for Hazardous Air Pollutants (NESHAPS). Subpart H protects the public and the environment from radioactive materials (other than radon) emission at DOE facilities and subpart I applies to other federal facilities, including NRC licensees. The basic criteria are that the annual effective dose equivalent to any individual... 

The Pipeline and Hazardous Materials Safety Administration s Hazardous Materials Regulations (49 CFR 171-180) contain specific requirements for the safe transportation of hazardous materials. The topic of security is specifically addressed in these regulations in Part 172, Subpart H (training) and Subpart I (security plans). Comphance with these regulations will improve the security of hazardous materials transportation. 

Training is one of the most important things that a hazmat employer can do to improve the safety and security of hazardous materials transportation. Subpart H of Part 172, requires each hazardous materials employer to train, test, and certify each hazardous materials employee on all applicable hazardous materials requirements. 

H. Safety considerations. The Occupational Safety and Health Administration (OSHA), US Department of Labor, standard entitled Occupational Exposure to Hazardous Chemicals in Laboratories (29 CFR 1910.1450) makes it necessary to address safety issues in the SOP. The standard requires laboratories that use hazardous chemicals to maintain employee exposures at or below the permissible exposure limits specified for these chemicals in 29 CFR Part 1910, Subpart Z. Hazards associated with any specific chemicals used in a method must be addressed so that the user has the information needed to follow the Chemical Hygiene Plan for their laboratory. The method developer should limit the use of hazardous chemicals where feasible. The use of toxic and/or carcinogenic reagents should be avoided or eliminated as much as possible. Additionally, the cost of disposal is increasing and could impact the practicality of a method. Material Safety Data Sheets for the analyte(s) and any unusual or hazardous reagents should be provided for the user.
