It is essential that laboratory employees have access to information on the hazards of chemicals and procedures for working safely. Supervisors must ensure that laboratory employees are informed about and have access to the following information sources:
"Occupational Exposure to Hazardous Chemicals in Laboratories" and its appendices (29 CFR 1910.1450), a copy of which is found in Appendix A of this Chemical Hygiene Plan.
which is available to all department employees and can be found on the Biology Department web site.
for OSHA regulated substances, which can be found in the University of Minnesota Laboratory Safety Plan, Appendix B. Also included are the ACGIH Threshold Limit Values (TLV). Table A lists select carcinogens, reproductive toxins, and chemicals having a high degree of acute toxicity documented in the biology department. A glossary following the tables defines various OSHA health hazards
to hazardous chemicals. Laboratory Chemical Safety Summaries (LCSSs) for 88 commonly encountered laboratory chemicals are included on pages 235-413 of the 1995 edition of Prudent Practices. LCSSs are similar to Material Safety Data Sheets (MSDS), but are tailored to the hazards of laboratory use of those chemicals. The LCSSs include toxicity information, and signs and symptoms of exposure to the chemicals.
for laboratory chemicals are located in department stockroom NSC130. On CSB/SJU networked computers, the CisPro 2000 MSDS filing cabinet (Network Programs, Department Specific Applications, MSDS DFCpro) contains electronic versions of the MSDSs of chemicals used in the biology department. This program is password protected.
Many manufacturers provide on-line MSDSs. Faculty and Staff who receive MSDS directly with chemical shipments will make such information available to the employees using the chemicals. Before ordering a chemical new to the department, they must obtain a copy of the MSDS and complete the "Information Required Prior to Ordering a Chemical Form" and submit to Carol Jansky for barcode and HMIS assignment.
Each laboratory supervisor is responsible for ensuring that laboratory employees are provided with training about the hazards of chemicals present in their laboratory work area, and methods to control exposure to such chemicals. Such training must be provided at the time of an employee's initial assignment to a work area where hazardous chemicals are present; and prior to assignments involving new potential exposure situations. Refresher training must be provided annually. Appendix E contains safety training confirmation and agreement forms. Appendix G contains an example of a training script.
(observation, odor, real-time monitoring, air sampling, etc.)
toxicity, hazard, exposure, routes of entry, acute and chronic effects, LD50, threshold limit values and permissible exposure limits, exposure time, and health hazards related to classes of chemicals;
including general techniques designed to reduce personal exposure and to control physical hazards, as well as specific protective mechanisms and warning systems used in individual laboratories. Appropriate use of fume hoods is to be specifically addressed;
including Material Safety Data Sheets;
appropriate to individual laboratories;
including general and laboratory-specific Standard Operating Procedures;
Including identification of whether chemical waste is hazardous, and proper disposal techniques.
