4 000 workers are employed in labora-tories in the The Laboratory environment canbe a hazardous place to work. Laboratory workersare exposed to numerous potential hazards includ-ing chemical, biological, physical and radioactivehazards, as well as musculoskeletal Safety is governed by numerous local,state and federal regulations. Over the years, OSHAhas promulgated rules and published Guidance tomake laboratories increasingly safe for document is intended for supervisors, principalinvestigators and managers who have the primaryresponsibility for maintaining laboratories undertheir supervision as safe, healthy places to workand for ensuring that applicable health, safetyand environmental regulations are Guidance in the form of Fact Sheets andQuickCards is also provided for certain hazardsthat may be encountered in laboratories.

5 There areseveral primary osha standards that apply tolaboratories and these are discussed below. Thereare also other osha standards that apply to variousaspects of Laboratory activities and these arereferred to in this Occupational Exposure to Hazardous Chemicalsin Laboratories standard (29 CFR ) wascreated specifically for non-production osha standards provide rules thatprotect workers, including those that who in labora-tories, from chemical hazards as well as biological,physical and Safety hazards. For those hazards thatare not covered by a specific osha standard, osha often provides Guidance on protecting workers fromthese hazards. This document is designed to makeemployers aware of the osha standards as well asOSHA Guidance that is available to protect workersfrom the diverse hazards encountered in laborato-ries.

6 The extent of detail on specific hazards provid-ed in this document is dependent on the nature ofeach hazard and its importance in a Laboratory set-ting. In addition to information on osha standardsand Guidance that deal with Laboratory hazards,appendices are provided with information on othergovernmental and non-governmental agencies thatdeal with various aspects of Laboratory Laboratory Safety Guidance booklet dealsspecifically with laboratories within the jurisdictionof Federal osha . There are twenty-five states andtwo Territories (Puerto Rico and the VirginIslands) that have their own osha -approved occu-pational Safety and health standards, which may bedifferent from federal standards, but must be atleast as effective as the federal your local or state osha office for furtherinformation.

7 More information on osha -approvedstate plans is available Safety andHealth AdministrationOSHA StandardsSection 5(a)(1) of theOccupational Safety andHealth Act of 1970(OSH Act), theGeneral DutyClause, requires that employers shall furnish toeach of his employees employment and a place ofemployment which are free from recognized haz-ards that are causing or likely to cause death or seri-ous physical harm to his employees. Therefore,even if an osha standard has not been promulgat-ed that deals with a specific hazard or hazardousoperation, protection of workers from all hazards orhazardous operations may be enforceable undersection 5(a)(1) of the OSH Act.

8 For example, bestpractices that are issued by non-regulatory organi-zations such as the National Institute forOccupational Safety and Health (NIOSH), theCenters for Disease Control and Prevention (CDC),the National Research Council (NRC), and theNational Institutes of Health (NIH), can be enforce-able under section 5(a)(1).The principal osha standards that apply to all non-production laboratories are listed below. Althoughthis is not a comprehensive list, it includes stan-dards that cover the major hazards that workers aremost likely to encounter in their daily must be fully aware of these standardsand must implement all aspects of the standardsthat apply to specific Laboratory work conditions intheir Occupational Exposure to Hazardous Chemicalsin Laboratories standard (29 CFR ), com-monly referred to as the Laboratory standard,requires that the employer designate a ChemicalHygiene Officer and have a written ChemicalHygiene Plan (CHP), and actively verify that itremains effective.

9 The CHP must include provisionsfor worker training, chemical exposure monitoringwhere appropriate, medical consultation whenexposure occurs, criteria for the use of personalprotective equipment (PPE) and engineering con-trols, special precautions for particularly hazardoussubstances, and a requirement for a ChemicalHygiene Officer responsible for implementation ofthe CHP. The CHP must be tailored to reflect thespecific chemical hazards present in the laboratorywhere it is to be used. Laboratory personnel mustreceive training regarding the Laboratory standard,the CHP, and other Laboratory Safety practices,including exposure detection, physical and healthhazards associated with chemicals, and Hazard Communication standard (29 ), sometimes called the HazCom standard,is a set of requirements first issued in 1983 byOSHA.

10 The standard requires evaluating the poten-tial hazards of chemicals, and communicating infor-mation concerning those hazards and appropriateprotective measures to employees. The standardincludes provisions for: developing and maintaininga written hazard communication program for theworkplace, including lists of hazardous chemicalspresent; labeling of containers of chemicals in theworkplace, as well as of containers of chemicalsbeing shipped to other workplaces; preparation anddistribution of material Safety data sheets (MSDSs)to workers and downstream employers; and devel-opment and implementation of worker training pro-grams regarding hazards of chemicals and protec-tive measures.
