2、dard Practice for Regulatory Information for Chemicals Used in AASHTO Tests AASHTO Designation: R 16-04 (2016) Release: Group 1 (April 2016) 1. SCOPE 1.1. This standard practice provides a reference listing of chemicals used in the various AASHTO Test Methods (see Table 1). It includes current regul
3、atory codes and hazard classifications. The list does not include radiation hazards. This practice is not intended as a substitute for law or regulation. 1.2. The chemical list must be provided to all laboratory employees engaged in performing AASHTO tests. In addition, all laboratory employees must
4、 be trained in proper handling procedures as stated in the OSHA 1910.1200 Hazard Communication Standard or governing state regulation. Laboratories performing AASHTO tests shall establish a Chemical Hygiene Plan as set out in 29 CFR 1910.1450, including the training requirements therein. 1.3. This p
5、ractice supplements data found in Material Safety Data Sheets (MSDSs) supplied by manufacturers. This practice is for quick reference ability and is not intended to replace MSDSs. 2. INTRODUCTION 2.1. In an effort to assure uniform compliance with regulations, the following definitions are cited: 2.
6、1.1. A hazardous chemical includes any substance that is in the definition of health hazard adopted by the United States Occupational Safety and Health Administration. 2.1.2. A hazardous waste includes, but is not limited to, any substance that has been assigned a code number from the EPA “Unlisted
7、(Characteristic) Hazardous Wastes” code. All hazardous waste must be disposed of in accordance with EPA, state, and local regulations. 2.2. Should there be any questions regarding whether a substance is hazardous, contact the local governing authority. 3. CHEMICAL LIST 3.1. This section contains def
8、initions of the terms and abbreviations contained in the list. All information is valid as of the date of this practice. 3.2. CAS No. is the number assigned to a substance by the Chemical Abstracts Service. 3.3. Test Method refers to the AASHTO test method in which the chemical is used. 2016 by the
