The intent of this Laboratory Safety and Chemical Hygiene Plan for the University of Wisconsin Oshkosh is:

1. To protect laboratory employees and students from health hazards associated with the use of hazardous chemicals in our laboratories;

2. To assure that our laboratory employees and students are not exposed to substances in excess of the permissible exposure limits (PEL's) as defined by the Occupational Safety and Health Administration (OSHA) and codified in 29 CFR 1910.1000, Table Z-1; and

3. To assist our laboratories' regulatory compliance with the OSHA Laboratory Standard as codified in 29 CFR 1910.1450.

This plan will be available to all employees and students for review and a copy will be located in the following areas:

 Chemistry Stockroom, HS 449

 Biology Stockroom, HS 135

This plan will be reviewed annually and updated as necessary.

I. Standard Operating Procedures

A.  Specific standard operating procedures for our laboratories are attached to this plan as Appendix A.

B.  Laboratory instructors have the responsibility to maintain safe standard operating procedures               and  maintain or revise the procedures as necessary or needed.

C.  The EH & S Officer, has the responsibility to conduct periodic laboratory inspections. At a minimum, an annual inspection will be done in each lab while the laboratory is in use.

D.  The chairpersons of the Biology and Chemistry Departments shall have the responsibility to see that this overall management plan is implemented and followed.

II. Control Measures to Reduce Employee Exposure to Hazardous Chemicals:


1.  Adequate ventilation is essential for maintaining safe levels of exposure. It shall be the responsibility of the laboratory supervisor to discontinue laboratory operations if ventilation is judged to be inadequate for any reason, such as equipment breakdown or accidental spillage.

2. Fume hoods shall be used for all operations which have the potential to produce gases vapors or fumes exceeding the PEL or TLV as given on the appropriate MSDS. Fume hoods shall not be used as chemical storage areas. Storing materials in fume hoods reduces their efficiency, and could lead to inadvertent mixing of incompatible chemicals. Where such use is necessary, it shall be designated as a storage area, not for operations and will be posted as such.

3. Fume hood airflow velocities will be checked annually by Facilities Management Personnel. Inspection results will be posted on each fume hood. Fume hoods with inadequate face velocities will be prominently marked as not suitable for use until repaired.

4. Air quality monitoring will be performed if laboratory supervisors report a condition which might lead to excessive exposure levels as given on the appropriate MSDS.

Storage and Handling

A current inventory of all hazardous chemicals shall be maintained. The Biology and Chemistry Storeroom Managers are responsible for preparing, maintaining and annually updating the hazardous materials inventory for all academic (teaching) laboratories. Faculty/staff assigned personal research areas are responsible for preparing, maintaining and annually updating a hazardous materials inventory for his/her assigned area.

Chemical inventories shall be kept to a minimum in working laboratories. Chemicals shall be stored in a safe manner utilizing, for example, chemical storage cabinets for corrosives and flammables. Chemicals shall be segregated by chemical characteristics to avoid incompatibilities. Alphabetical storage may be used only if chemical characteristics are compatible.

All chemical containers shall be kept capped or lidded when chemicals are not being withdrawn or added. This includes hazardous waste accumulation containers.

Adequate security for chemical storage areas is essential to minimize theft possibilities. Labs shall be locked when competent individuals are not present. Competent individuals shall be those persons trained by a supervising faculty/staff member or principal investigator to perform their work safely, recognize hazards and take appropriate action.

PPE(Personal Protective Equipment)

Routine laboratory personal protective equipment should include protective eyewear when working with hazardous chemicals. Gloves should be worn for work with strong corrosives or with acutely toxic chemicals. Special procedures may require special protective equipment.  Faculty/staff supervising special procedures are responsible for ensuring that protective equipment is used and special operating procedures are followed. See Appendix C for Campus Eye Protection Policy.

Respirators may only be worn when engineering controls cannot keep exposure to chemicals below permissible exposure levels (PELs) set by OSHA. Employees may not wear a respirator until they have completed required elements of the Campus Respirator Program. Please contact the EH & S Office for additional information.

Safety Equipment

FMC coordinates annual fire extinguisher inspections.  All faculty/staff are required to maintain clear access and visibility of fire extinguishers.

Eye wash stations and emergency showers shall be available in areas where the eyes or body of a person may be exposed to injurious materials. Eye wash and emergency showers shall be in an accessible location that requires no more than 10 seconds to reach and shall be identified with highly visible signage. Eye wash stations should be flushed monthly by designated personnel.  Emergency showers shall be checked by Facilities staff with maintenance documented on the attached tag. Employees will be instructed on the location and proper use of eye wash and emergency showers.

Additional Provision

Provisions for additional employee protection must be in place for work with particularly hazardous substances including select carcinogens, reproductive toxins, and substances which have a high degree of acute toxicity. Provisions will include designating areas for their use, use of containment devices such as a fume hood or glove boxes, safe removal of contaminated waste and appropriate decontamination procedures.  The Campus policy on the use of Carcinogens is found in Appendix B.
