工业安全卫生组织内容摘要：

gles should be worn at all times while working with chemicals at the counter or laboratory hood. A face shield should be worn when working with potentially eruptive substances. • Custodians, maintenance workers, and visitors must observe safety rules, including eye protection, while in the laboratory. • Wear protective gloves and clothing whenever handling corrosive or other hazardous chemicals. • Wear closedtoe shoes at all times in the lab. • Be sure that moving parts of mechanical apparatus are guarded to prevent hazardous contact. • Maintain your lab area reasonably neat and uncluttered. • Use the fume hood for all operations involving harmful gases or fumes and for flammable or explosive materials. Check the hood to see that it is operating adequately and has been inspected annually. PERSONAL PROTECTION, CLOTHING, AND HAIR 2 • Use a safety shield or barrier to protect against explosion, implosion, and flash fires when performing reactions with large volume of flammable liquids or unstable material. • Inspect glassware for cracks, sharp edges, and contamination before using. Broken or chipped glassware should be repaired and polished or discarded. • Always use a lubricant (., water, glycerol) when inserting glass tubing into rubber stoppers or grommets. Protect hands in case tubing breaks. • Broken glass should be put in impervious containers that are large enough to pletely contain the glass. These containers are to be placed into the building trash dumpsters by laboratory personnel, not by custodians. • Do not handle radioactive isotopes without concurrence of the Radiation Safety Officer. CHEMICAL HANDLING • Use a safety pail for transporting dangerous or flammable liquids of more than a small quantity (one pint). Use means to prevent tipping of containers when transporting materials on a cart. • Do not work with large quantities of reactants without special precautions. • Never pour anything back into a reagent bottle. • Use caution when adding anything to a strong acid, caustic, or oxidant. Add slowly. • Never add solids (boiling chips, charcoal, etc.) to a hot liquid. • Never pipet chemicals by mouth. Use a pipet。
