Employees who may be exposed to hazardous chemicals while working on campus should be kept informed of the nature of the hazards and instructed in methods to protect themselves. RMS can help evaluate the effectiveness of your controls by monitoring exposures to a variety of laboratory materials. Exposure monitoring is the determination of the airborne concentration of a hazardous material in the work environment. Some of the chemicals used in the laboratory are OSHA regulated and have exposure monitoring and medical surveillance requirements. Exposure to chemical substances regulated by OSHA 29 CFR 1910 Subpart Z requires monitoring, either initially or periodically, shall be monitored according to the standard. These requirements are activated when the concentrations of these chemicals meet or exceed exposure levels determined by OSHA.
Medical surveillance is the systematic assessment of employees exposed or potentially exposed to occupational hazards. This assessment monitors individuals for adverse health effects and determines the effectiveness of exposure prevention strategies.
If the initial monitoring discloses exposure over the permissible exposure limit (PEL) then immediate compliance with the exposure and medical monitoring provisions of the relevant standard is required. Compliance with the standard may include more frequent monitoring and implementation of additional control measures.
Personnel shall be notified in writing of monitoring data within 15 days of receipt of those monitoring results.
