1. Chemical Hygiene Plan
(CHP)
A written plan that describes
how exposure to hazardous
chemicals will be reduced in
the laboratory.
•Refer to it any time you have a
question about your lab or
need to review particular
information!
•
Required elements of the CHP
Criteria for reducing employee
exposure to hazardous chemicals.
 Use of personal protective
equipment.
 ensure fume hoods and other
protective equipment are functioning
properly.
 Provisions for employee training.

Required elements continued:
Circumstances requiring employer
approval of certain laboratory
operations, procedures, or activities
before implementation.
 Provisions for medical consultation.
 Measures to protect employees from
particularly hazardous substances.
 Assignment of a Chemical Hygiene
Officer.

2. Chemical Hygiene Officer




Develops and implements appropriate
chemical hygiene policies and practices.
Conducts monthly checks of safety
equipment
Ensures that laboratory users are
educated on all elements of the chemical
hygiene plan.
The CHO will be available to answer any
questions the laboratory users might
have.
3. Provide Employee Information &
Training
Laboratory users are required to
receive information and training
concerning the hazards that they will
encounter in the laboratory prior to
engaging in laboratory work.
What information is required?



The contents of the Laboratory Standard
shall be made available to employees
The location and availability of the
employer's Chemical Hygiene Plan
The permissible exposure limits
What information is required?


Signs and symptoms associated with
exposures to hazardous chemicals
used in the laboratory
MSDS
What training is required?


Methods and observations that may
be used to detect the presence or
release of a hazardous chemical
The physical and health hazards of
chemicals in the work area
What training is required?


Measures employees shall take to
protect themselves from hazards.
The employee shall be trained on the
applicable details of the laboratory's
written Chemical Hygiene Plan.
4. Medical Consultations

The employer shall provide all
employees who work with hazardous
chemicals an opportunity to receive
medical consultations
The employer shall provide the
following information to the
physician:


The identity of the hazardous
chemical(s) to which the employee
may have been exposed
A description of the conditions under
which the exposure occurred
What will a medical consultation
cost the employee?

All medical examinations shall be
provided without cost to the
employee, without loss of pay and at
a reasonable time and place
5. Recordkeeping.

The employer shall establish and maintain
for each employee an accurate record of
any measurements taken to monitor
employee exposures and medical
consultations
6. Monitoring-Exposure Level
Determination


Initial monitoring. The employer shall measure
the employee's exposure to any substance if
there is reason to believe that exposure levels for
that substance routinely exceed the action level
(or in the absence of an action level, the PEL).
Periodic monitoring. Periodic monitoring must be
conducted if initial monitoring finds that a
hazardous exposure has occurred.
Monitoring-Exposure Level
Determination
Termination of monitoring.
Monitoring may be terminated when
PEL’s or action levels are maintained
at an acceptable level
 Employee notification of monitoring
results. The employer shall, within
15 working days after the receipt of
any monitoring results, notify the
employee of these results.

7. Hazard Identification


labels on incoming containers of
hazardous chemicals shall not be
removed or defaced.
Material safety data sheets must be
maintained with incoming shipments
of hazardous chemicals.
The following provisions shall apply
to chemical substances developed
in the laboratory:

If the composition of the chemical
substance which is produced
exclusively for the laboratory's use is
known, the employer shall determine
if it is a hazardous chemical
The following provisions shall apply
to chemical substances developed
in the laboratory:

If the chemical is determined to be
hazardous, the employer shall
provide appropriate training for the
substance.
8. Permissible Exposure Limits

The employer shall assure that
laboratory employees' exposures to
hazardous substances do not exceed
the permissible exposure limits
9. Respirators
Where the use of respirators is
necessary to maintain exposure
below permissible exposure limits,
the employer shall provide, at no
cost to the employee, the proper
respiratory equipment.
 Prior to using any respirator you
must first be medically monitored, fit
tested and trained.

