Lab Standard/HazComm
Lab Standard vs. Hazard Communication
Who is required to have training:
“Under OSHA, the term ‘worker’ refers to everyone who
receives an employer paycheck for their work.
MTU safety policies require OSHA-mandated safety
training and compliance measures to be applied to
unpaid workers such as visiting scholars/scientists,
graduate students that do not receive a University
paycheck, and undergraduate students involved in
University sponsored work other than registered courses.”

CH Dept Chemical
Hygiene Plan
The chemical hygiene plan shall include each of the
following elements and shall indicate specific
measures that the employer will take to ensure
laboratory employee protection:
(a) Standard operating procedures relevant to safety
and health considerations to be followed when
laboratory work involves the use of hazardous chemicals.
(b) Criteria that the employer will use to determine and
implement control measures to reduce employee
exposure to hazardous chemicals, including
engineering controls, the use of personal protective
equipment, and hygiene practices.
CH Dept Chemical
Hygiene Plan
(c) A requirement that laboratory-type hoods and other
protective equipment are functioning properly and the
specific measures that shall be taken to ensure the proper
and adequate performance of such equipment.
(d) Provisions for employee information and training as
prescribed in R 325.70107.
(e) The circumstances under which a particular laboratory
operation, procedure, or activity shall require prior
approval from the employer or the employer's designee
before implementation.
CH Dept Chemical
Hygiene Plan
(f) Provisions for medical consultation and medical
examinations in accordance with R 325.70108.
(g) Designation of personnel who are responsible for
implementing the chemical hygiene plan, including the
assignment of a chemical hygiene officer and, if
appropriate, establishment of a chemical hygiene
committee.
(h) Provisions for additional employee protection for work
with particularly hazardous substances, such as select
carcinogens, reproductive toxins, and substances that
have a high degree of acute or chronic toxicity.
CH Dept Chemical
Hygiene Plan
(h) (cont.) Specific consideration shall be given to the
following provisions, which shall be included where
appropriate:
(i) The establishment of a designated area or areas
that indicate the physical limits of exposure to
particularly hazardous substances.
(ii) The use of containment devices, such as
laboratory-type hoods or glove boxes.
(iii) Procedures for the safe removal of contaminated
waste.
(iv) Decontamination procedures.

Permissible Exposure
Limits
What are permissible exposure limits?
“Time-weighted average (TWA)” means the
employee’s average airborne exposure in any 8-hour
workshift of a 40-hour workweek that shall not be
exceeded.
“Short-term exposure limit (STEL)” means the
employee’s 15-minute, time-weighted average
exposure which shall not be exceeded at any time
during a workday….
“Ceiling” means the employee’s exposure which shall
not be exceeded during any part of the workday.
Permissible Exposure
Limits
Where can I find permissible exposure limits?
• A paper copy is available in the chemistry office

• Exposure monitoring is required by the Lab Standard
“…if there is reason to believe that exposure levels…
routinely exceed…the permissible exposure limits (PEL).”
• MTU has no system for exposure monitoring
Continuous monitoring devices
• MTU has no system for continuous monitoring

MTU Hazard Communications labeling rules
http://www.sas.it.mtu.edu/fm/oshs/
hazcom_program/labeling.htm
CH Dept Chemical
Hygiene Plan
The labels on all containers will include:
• The identity of the hazardous chemical(s);
• Appropriate hazard warnings or combination of words,
pictures, and symbols that provide at least general
information regarding the hazards of the chemicals,
and which, in conjunction with the other information
immediately available to employees under the hazard
communication program, will provide employees with
the specific information regarding the physical and
health hazards.
• The hazard warnings and information must also be in
accordance with the labeling requirements of any
substance-specific standards applicable to the chemical.
