Significance and Use3.1 This practice is issued to provide information useful in
7、establishing sampling and handling procedures. It is expectedthat this information will only be utilized in conjunction withan existing health and safety program and consultation with anappropriate MSDS. The information provided herein cannot beused as a substitute for expert safety and medical advi
8、ce asprovided in an appropriate MSDS, but rather as a supplementto such advice.4. Description of Product (See Table 1)4.1 Bisphenol A (BPA) is not classified as a hazardouschemical by the Department of Transportation, and is, thereforenot subject to DOT regulations governing the transportation ofhaz
9、ardous articles. Bisphenol A is normally transported inseveral types of containers including cloth and paper bags, bulktrucks, and covered hopper cars. (See Table 1.)4.2 While bisphenol A (BPA) is dangerous when handledimproperly, particularly at elevated temperatures, its unloadingneed not be hazar
10、dous provided the hazards are recognized andhandling instructions are rigidly observed as detailed here andin an appropriate MSDS.5. Hazards5.1 HealthConsult current OSHA regulations and suppli-ers Material Safety Data Sheets for all materials used in thispractice.5.1.1 Aside from the risk of therma
11、l burns in handling BPAwhen molten, and a possibility of dermatitis from impurities,particularly in crude grades, industrial use does not present asignificant health hazard. However, ordinary precautions mustbe observed to protect personnel from contact with moltenBPA or excessive exposure to dusts
12、or high concentrations ofvapor.5.1.2 Precautions must be observed to protect personnelfrom excessive inhalation of vapors and dust.5.2 Fire:5.2.1 BPA in both the solid and liquid form is combustibleand introduces a potential fire hazard when it is stored,handled, or used.5.2.2 BPA vapors or dust can
13、 form explosive mixtures withair.5.2.3 Dry chemicals, carbon dioxide, foam, and water canall be used in fighting fires involving BPA.1This practice is under the jurisdiction of ASTM Committee D16 on AromaticHydrocarbons and Related Chemicals and is the direct responsibility of Subcom-mittee D16.08 o

Protective Equipment6.1 Employees who work with BPA should be wel
16、l trainedand should maintain safe working conditions. They should berequired to read an appropriate MSDS for BPA in its entiretyand consult appropriate, local, safety personnel if they haveany questions or concerns. Persons handling moltenbisphenol-A need to exercise particular care.7. First Aid7.1
17、Consult an appropriate MSDS for BPA with regards tofirst aid measures that should be taken. In particular, extremecare must be observed handling molten BPA as it can causesevere thermal burns.8. Safety Precautions8.1 Exercise care to prevent spills and leaks. If they dooccur, only properly protected
18、 personnel should remain in thecontaminated area in accordance with the instructions in anappropriate MSDS. All spill-related activities should complywith applicable EPA, OSHA, and local regulations and laws.8.2 Because of fire and dust explosion hazards, do notpermit open flames in the vicinity of
19、tank carriers, othershipping containers, or storage tanks. Provide all electricalfixtures with vapor-proof globes and explosion-proof safetydevices. Ground tank carriers by an approved method. Prohibitsmoking. All pneumatic conveying should be done withnitrogen or other inert gas.8.3 Any person samp
20、ling or handling these products shouldhave consulted an appropriate MSDS for specific first aidinstructions and equipment to have available for use in theevent of personal contact or exposure.8.4 Conduct sampling and handling operations in accor-dance with the instructions in an appropriate MSDS.9.
21、Unloading Hopper Cars or Hopper Trucks9.1 Observe all safety precautions as outlined in Section 8and in an appropriate MSDS. Always follow shippers instruc-tions for unloading, and read and observe all caution markingson both sides of the hopper or dome.9.2 Opening of the hopper car dome cover and a
22、ttachmentof delivery lines should all be done by accepted safetyprocedures.10.
