Downloaded from https://www.everyspec.com Hazard class The United Nations Organization hazardous classification system, which contains 9 hazard classes, is used by the DOD for dangerous materials to identify the hazardous characteristics of A&E. Hazard Class 1 (A&E) is further divided into six division designators that indicate the primary characteristics and associated hazards. Hazard classification An assignment of A&E (class 1 substances) into one of six divisions for purposes of storage, transportation, and QD computations. These divisions are— 1.1–mass detonating. 1.2–fragment producing. 1.3– mass fire. 1.4–moderate fire.
1.5–very insensitive explosives and blasting agent (used by the Army for transportation only). 1.6–extremely insensitive ammunition. Hazardous materials (HAZMAT) Definitions are— a. “Hazardous material” means any material that has been designated as hazardous under 49 USC 5101 to 49 USC 5127 and is required to be placarded under 49 CFR 172, Subpart F or any quantity of material listed as a select agent or toxin in 42 CFR 73. b. Substances that have hazardous characteristics such as flammable, corrosive, reactive, toxic, radioactive, poison- ous, carcinogenic or infectious, having properties capable of producing adverse effects on the health and safety or the environment of a human being.
Legal definitions are found in individual regulations. c. Any substance or material that when involved in an accident and released in sufficient quantities, poses a risk to people’s health, safety, and/or property. These substances and materials include explosives, radioactive materials, flammable liquids or solids, combustible liquids or solids, poisons, oxidizers, toxins, and corrosive materials (Federal Emergency Management Agency definition). d. The DOT uses the term hazardous materials which covers 8 hazard classes, some of which have subcategories called classifications and a ninth class covering other regulated materials.
The DOT includes in its regulations hazardous substances and hazardous wastes as other regulated materials-E, both of which are regulated by the EPA, if their inherent properties would not otherwise be covered. Hazardous substances Two forms of definitions— a. The EPA uses the term hazardous substance for the chemicals that, if released into the environment above a certain amount, must be reported and depending on the threat to the environment, Federal involvement in handling the incident can be authorized. A list of the hazardous substances is published in 40 CFR 302, Table 302.4. b.
The OSHA uses the term hazardous substance in 29 CFR 1910.120, which resulted from Title I of SARA and covers emergency response. OSHA uses the term differently than EPA. Hazardous substances, as used by OSHA, cover every chemical regulated by both DOT and EPA. HC smoke Hexachloroethane-zinc oxide used to generate screening smoke. Health hazard An existing or likely condition, inherent to the operation, maintenance, storage or disposal of materiel or a facility, that can cause death, injury, acute or chronic illness, disability, or reduced job performance.
Health hazard assessment The applications of biomedical and psychological knowledge and principles to identify, evaluate, and control the risk to the health and effectiveness of personnel who test, use, or service Army systems. Hospitalization Admission to a hospital as an inpatient for medical treatment. Human error Human performance that deviated from that required by the operational standards or situation. Human error in 116 AR 385–10 • 23 August 2007
