Chemical Hygiene Program
Occupational Exposures to Hazardous Chemicals in Laboratories
October 10, 1991
- The purpose of this rule is to provide a
safe and healthy work environment for all laboratory employees at
Kansas State University. Laboratory workers includes classified and
unclassified personnel, graduate students, and student employees but
does not include students in a laboratory classroom situation. This
occupational health rule is patternedafter the Federal Occupational
Safety and Health Administration's (OSHA) 29 CFR 1910.1450 as adopted
by the Kansas Department of Human Resources under K.S.A. 44-636 and
-637. Kansas State University is subject to regulations promulgated by
the Kansas Department of Human Resources and not OSHA. The Federal OSHA
has no authority on campus. The university is voluntarily adopting this
Federal standard as a means of providing safe laboratory practices on
campus. This standard applies to all colleges on Kansas State
University campuses that engage in the laboratory use of hazardous
- This rule does not apply in those
laboratory uses of hazardous chemicals which provide no potential for
employee exposure. Examples are: the use of "Dip and Read" test where a
reagent strip is dipped into the specimen and the results are
interpreted by comparing the color reaction to a color chart; and the
use of completely self-contained commercially prepared kits.
- The Department of Environmental Health and
Safety will designate an employee as the university's Chemical Hygiene
- The Chemical Hygiene Officer will provide
technical guidance and assistance for the implementation of the
Chemical Hygiene Plan. This individual will work with departments to
ensure proper compliance with the safety rules of Kansas State
University. These rules include but are not limited to the rules in the
LABORATORY SAFETY MANUAL, the SAFETY WITH CHEMICAL CARCINOGENS IN
RESEARCH AND TEACHING, the RADIATION SAFETY MANUAL, the RESPIRATOR
PROGRAM, and the HAZARD COMMUNICATION PROGRAM. The written Chemical
Hygiene Plan is contained in this CHEMICAL HYGIENE PROGRAM OF KANSAS
- Each Department Head is required:
- to ensure that the Chemical Hygiene
Officer gets the cooperation of all laboratory workers in the
- to limit employee chemical exposures to
the American Conference of Governmental Industrial Hygienists (ACGIH)
threshold limit value (TLV) calculated as an 8-hour time weighted
average for those hazardous chemicals encountered in the laboratory;
- to provide the proper engineering
controls or personal protective equipment which prohibits eye and skin
contact of hazardous chemicals;
- to provide employee exposure monitoring
and medical surveillance in the event that the ACGIH TLV is routinely
- to implement the Chemical Hygiene Plan;
- may delegate these duties to the
respective laboratory supervisor, manager, or department authority.
- EMPLOYEE EXPOSURE MONITORING
- Initial Monitoring. The Department Head
will provide adequate employee monitoring for substances that are
regulated by a health standard that require monitoring, such as
formaldehyde or ethylene oxide, if there is reason to believe that
exposure levels routinely exceed the TLV.
- Periodic Monitoring. If initial monitoring
discloses employee exposure above the TLV, the Department Head will
comply with the exposure monitoring provisions of the relevant
- Employee Notification of Monitoring
- The Chemical Hygiene Officer will
notify the Department Head within 15 working days after the receipt of
any monitoring results.
- The Department Head will notify the
employee(s) in writing either individually or by posting results within
15 working days after the receipt of any monitoring results.
- CHEMICAL HYGIENE PLAN
- University Laboratory Safety Rules. The
Department Head will ensure that employees comply with published campus
Laboratory Safety Manual, Safety with Chemical Carcinogens in Research
and Teaching, Radiation Safety Manual, Hazard Communication Program,
the Respirator Program, this Chemical Hygiene Program and any other
rules set as policy by the Environmental Health and Safety Committee.
- Department Standard Operating Procedures.
The Department Head will ensure that employees comply with written
standard operating procedures that may be provided by the department.
- Training. The Department Head will ensure
that employees are trained to understand the hazards of the laboratory
they work in and the hazards of the materials they work with. Training
shall include appropriate work practices, emergency procedures, and
personal protective equipment to be used.
- Medical Consultation and Examinations.
- The Department Head will provide all
employees covered by this Chemical Hygiene Program an opportunity to
receive medical attention which an examining physician determines to be
- an employee develops signs or
symptoms associated with a hazardous chemical to which the employee may
have been exposed in the laboratory;
- environmental monitoring reveals an
exposure level above the TLV; or
- a chemical spill, leak, explosion
or other event takes place which results in the likelihood of a
hazardous chemical exposure.
- All medical examinations and
consultations should be performed by or under the direct supervision of
a licensed physician and should be provided without cost to the
employee, without loss of pay, and at a reasonable time and place.
- The Department Head will provide the
following information to the physician:
- the hazardous chemical(s) to which
the employee may have been exposed;
- the exposure conditions including
any quantitative data; and
- any signs or symptoms exhibited by
- The physician's written opinion.
- The examining physician will submit
to the Department Head a written opinion which includes the following:
- any recommendation for further
- the results of the medical
examination and any associated tests;
- any medical condition which may
be revealed in the course of the examination which may place the
employee at increased risk as a result of exposure to a hazardous
chemical found in the work place; and
- a statement that the employee
has been informed by the physician of the results of the consultation,
medical examination or treatment.
- The written opinion shall not
reveal specific findings of diagnoses unrelated to occupational
- Where respirator use is necessary to
maintain exposure below the TLV, the Department Head will provide, at
no cost to the employee, the proper respiratory equipment. Respirators
shall be selected and used in accordance with 29 CFR 1910.134 as
adopted by K.S.A. 44-636 and -637, and the Respirator Program at Kansas
State University. Every effort will be made by the Department Head to
provide the necessary engineering controls to relieve the need for
- The university shall establish and
maintain for each laboratory employee an accurate record of any
measurement taken to monitor employee exposures and any medical
consultation and examination including tests or written opinions
required by this standard.
- The university shall assure that
such records are kept, transferred, and made available in accordance
with 29 CFR 1910.20 as adopted by K.S.A. 44-636 and -637.
