3. Occupational Safety and Health administration( osha ) Occupational Safety and Health Act of 1970 “To assure safe and healthful working conditions for working men and women by authorizing enforcement of the standards developed under the Act by assisting and encouraging the States in their efforts to assure safe and healthful working conditions by providing for research, information, education, and training in the field of occupational safety and health.” 3

5. For a laboratory to be governed by the standard, the lab must meet specific criteria. covered under the rule are workplaces that use relatively small quantities of hazardous chemicals. Multiple chemical procedures or chemicals are used, and the procedures involved are not part of a production process. These laboratories must use or handle hazardous chemicals and manipulate them on a “ laboratory scale ” basis.

6. 6 In promulgating this standard, OSHA placed primary emphasis on administrative controls to lessen the threat of overexposure to hazardous substances in laboratories Administrative controls consist of various hazard control requirements that are established at a managerial level by an appropriate individual or group (e.g., laboratory manager, laboratory supervisor, or safety committee) to promote safety in the laboratory. 

7. Administrative controls do not remove hazards, but reduce or prevent exposure to them. Some common examples of administrative controls include written plans and procedural controls (e.g., safe work practices and standard operating procedures), training and information, exposure monitoring, medical examinations, hazard identification, and record keeping.   7

8. For those people who have the primary responsibility for maintaining laboratories under their supervision, the laboratory standard consists of the following major elements : Exposure monitoring Chemical hygiene plan Employee information and training Medical consultation and medical examinations Hazard identification Use of respirators Record keeping 8

9. 9 The employer must ensure that laboratory workers are not exposed to these chemicals above their respective permissible exposure limits (PELs). The employee must  measure the worker's exposure to any chemical regulated by a standard, which contains exposure monitoring and medical surveillance requirements if there is reason to believe that exposure levels for that chemical routinely exceed the action level, or in the absence of an action level, the PEL. Exposure monitoring

10. Chemical hygiene plan (CHP) Standard operating procedures (SOPs) Implementation of exposure control measures Proper functioning of lab hoods and other protective equipment Information and training Laboratory activities requiring prior approval Medical consultation and examinations Designation of responsible personnel Special precautions for particularly hazardous substances 10 The CHP must include the following specific elements:

11. Information and training The contents of this standard and its appendices The CHP and safety data sheets (SDS) Permissible exposure limits for OSHA regulated substances used in the work area or recommended exposure limits for other hazardous chemicals in the absence of an OSHA standard Signs and symptoms associated with exposures to hazardous chemicals used in the laboratory Reference materials (e.g., SDSs) which detail the hazards, safe handling, storage, and disposal of hazardous chemicals 11 Information and training are essential tools for informing workers and managers about workplace hazards and controls so they can work more safely and be more productive. Information that is to be communicated and made available to the employees include the following:

12. Medical consultation and examinations The employer must provide all employees who work with hazardous chemicals the opportunity to receive appropriate medical attention. The employer must also provide employees with an opportunity to receive a medical consultation whenever an event takes place in the work area, such as a spill, leak, explosion, or other occurrence resulting in the likelihood of significant exposure to a hazardous chemical. The medical consultation is provided to determine the need for a medical examination. The employee must be allowed to receive any examinations recommended by the physician. All medical examinations and consultations must be performed by or under the direct supervision of a licensed physician and provided at a reasonable time and place, without cost or loss of pay to the employee.  12

13. Hazard identification To ensure chemical safety in the laboratory, information about the identities and hazards of the chemicals must be available and understandable to workers. The following provisions apply to laboratory-generated chemical substances: - The chemical is produced exclusively for the laboratory's use - The chemical produced is a byproduct - The chemical is produced and shipped to another user outside of the laboratory 13

14. Record keeping The employer must establish and maintain for each employee an accurate record of any measurements taken to monitor employee exposure and any medical consultation and examinations, including tests or written opinions required by this standard The employer must assure that such records are kept Accurate records of work-related injuries, illnesses, and fatalities must be established and maintained 14
