Chemical Handling
Never
smell or taste chemicals.
Always
Never
assume a chemical is hazardous.
use chipped or broken glassware.
Always
place chemicals back from the edge of
shelves, tables, or benches.
Use
only the amount needed.
Waste
chemicals will be handled in accordance with
the University’s Hazardous Waste Program.
KEEP
WORK AREA CLEAR AND UNCLUTTERED.
Eye Protection
•
•
•
•
Safety goggles must be
worn while engaged in
laboratory activities that
involve use of liquid
chemicals injurious to the
eyes.
Safety glasses with side
shields only protect
against particles.
The use of face shields
are required when there
is the potential of large
splashes with corrosive
chemicals.
Contact lenses shall not
be worn in laboratories.
Lab Coats
•
Clothing items made with synthetic fabrics will melt in
heat or fire causing severe burns. Lab coats are
generally made of cotton or specialized fabrics that will
not melt.
•
If a chemical splashes onto your lab coat or your coat
catches on fire – you can easily take the coat off. It is
more difficult to remove contaminated clothing.
•
Lab coats protect your skin from spills and splashes that
may occur during regular laboratory exercises.
•
Lab coats protect your street clothes from dirt and nonobvious contamination in the lab.
Gloves
• Wear appropriate
gloves whenever
using particularly
hazardous
substances or
chemicals with
significant skin
damaging or skin
absorbing potential.
Penetration- the bulk flow of chemical
through tears, rips, pinholes, and other
damage through the glove material.
Permeation – the diffusion of a
chemical on a molecular basis through
chemical protective clothing.
Degradation- the change in physical
properties of protective material as a
result of adverse effects of chemical.

Fume Hood Components
Airfoil: streamlines airflow
into hood to help prevent
turbulent eddies
Baffles: help keep a
uniform airflow across the
face of the hood
Sash: closes/opens hood
Work Surface: set-up all
work at least 6” from the
airfoil
Laboratory
Hoods
•Keep
hoods free of
clutter.
•Do
not use hoods for
general chemical
storage.
•Position
gas phase or
particle generating
sources well within hood.
•Align
sash at arrow
when working in the
hood.
Do not use fume hoods as
storage cabinets.
Large containers or equipment,
such as shaker tables, water
baths, or numerous chemical
containers will interfere with
airflow inside the chemical fume
hood by causing reverse flows
and dead spots. These dead
spots may allow contaminants
to escape from the hood.
Placing large equipment on legs
or blocks will help reduce a
reverse airflow by allowing air to
circulate beneath the
equipment.
Option:
Taping tissue to
the fume hood
sash will provide
a visual
indication of air
flow.
It’s important not to
block fume hood air
flow.
When large
equipment needs to
be placed in a fume
hood, place
equipment on blocks
or racking to allow air
flow under the
equipment.
Improper
placement of
beta radiation
shields can
block airflow
and
significantly
reduce the
effectiveness
of the fume
hood.
Emergency Eyewash and
Shower Units
- Never
store
anything in front of
eyewash/shower
units.
- Make sure you
know where the
eyewash/shower
unit is in lab and
how it works.
Accidental Splash Procedure
If someone gets a chemical in their
eye or on their skin they should
follow this procedure:
1.
Get to the eyewash/shower unit quickly. Your
vision may be impaired so get help if needed.
2.
When you get to the eyewash/shower unit, start
flushing your eyes and/or skin immediately. You
may need help holding your eyelids back so the
water makes good contact with your eyes. If the
spill occurred on your skin, remove your clothing
as quickly as possible to reduce the contact time
of the chemical on your skin.
3.
Continue washing for 15 minutes.
4.
While washing, have someone contact 911.
Near Miss Accident Reporting
•An
incident that could have resulted in an injury, death,
pollution, damaged equipment.
•The
EH&S department ask that near misses be reported.
• A near miss can be viewed as a learning
opportunity.
• Our department will likely perform a evaluation
of the near miss. Nobody will go to jail for
reporting what happened.
Electrical
- Always make sure
electrical equipment is
properly grounded
-
Never remove the
grounding prong on a
three-prong electrical plug.
- Never modify a threeprong plug to use in a twoprong outlet.
Sharps
Dispose
of sharps in
approved sharps containers.
Never recap needles.
Sharps containers
should be disposed of
when they are ¾ full.
Dispose
of broken glass and
other sharps in appropriately
labeled containers.
Broken glass
receptacles will be
installed in laboratories.
Chemical Storage
• Only authorized
individuals should have
access to chemicals.
• Segregate incompatible
materials to prevent
contact with one another.
Chemical Storage: Example Storage Pattern
ChemAlert* Storage Codes
Flammable. Store in area segregated for flammable reagents.
RED (R)
BLUE (B)
YELLOW (Y)

Skin. Store in secure area.
Reactive and Oxidizing Reagents. May react violently with
air, water, or other substances. Store away from flammable
and combustible materials
WHITE (W)
Corrosive. May harm skin, eyes, mucous membranes.
Store away from red-, yellow-, and blue-colored regents above.
GREY (G)
Presents no more than moderate hazard in any of categories
above. For general chemical storage.
Exception. Denoted by the word “STOP.” Reagents
Incompatible with other reagents of the same color bar. Store
separately.
Chemical Storage
•
Secure compressed
gas cylinders by
chain or strap.
•
Keep protective cap
on cylinders not in
use.
Flammable and Combustible Liquids
Flammable:
A liquid with a flashpoint below 1000 F.
Combustible:
A liquid with a flashpoint at or above 1000 F but
below 2000 F.
Flashpoint:
The lowest temperature at which a flammable liquid
gives off sufficient vapor to form an ignitable mixture
with air near its surface or within a vessel.
Chemical Storage – Flammables
•
Make use of flammables
cabinets as much as you can.
•
Do not store chemicals of
different hazard classes in
flammables cabinets.
Ultraviolet Light
Exposing the skin to ultraviolet light
can cause erythema (redness of the
skin), photosensitivity, cancer, etc.
The International Agency for
Research on Cancer (IARC) has
found that ultraviolet light in all UV
regions are probably carcinogenic to
humans.
The eye is also impacted from
unprotected exposure to ultraviolet
light. The cornea and conjunctiva
absorb various wavelengths of UV
light and can cause photokeratitis
and photoconjunctivitis from acute
exposures.

PROTECTION ON THE JOB
Designed
THE PUBLIC EMPLOYMENT RISK REDUCTION ACT WAS ENACTED
TO PROVIDE SAFE AND HEALTHFUL WORKING CONDITIONS FOR
OHIO’S PUBLIC EMPLOYEES.
Employer Duties:
Employee Duties:
Enforcement:
Each public employer shall provide a place of employment free
from recognized hazards.
Each employee shall comply with all safety and health standards,
rules, and regulations.
The Ohio Department of Commerce will:
1.
Inspect job sites for unsafe and unhealthful conditions following a request to do so by a public
employee, public employee representative, or public employer.
2.
Issue citations requiring public employers to correct safety and health violations.
Refusal to Work: Any public employee acting in good faith may refuse work under conditions reasonably believed
to present an imminent danger of death or serious physical harm, provided that the condition is
not such as normally exists or reasonably might be expected to occur in the normal and regular
duties of the employee. In the case of refusal to work, the public employee must follow these
three steps and if all of the conditions in this rule are not met, the public employee may be subject
to disciplinary action pursuant to law or agreement:
1.
Notify his or her immediate supervisor of the imminent danger condition.
2.
If the employer declines to correct or disputes the condition, the employee must attempt to
contact the director of the Division of Occupational safety and Health and/or a representative
of the Division knowledgeable of Risk Reduction standards and workplace hazards.
3.
Submit a written statement of the imminent danger to the Chief of the Bureau of Occupational
Safety and Health as soon as practical.
Complaints:
Any public employee or employee representative may file a complaint with the Ohio Department of
Commerce of any unsafe or unhealthful condition or practice by letter or by fax. Employees should
initially attempt to have unsafe or unhealthful conditions corrected through their own procedures
by contacting their immediate supervisor.
Inspections:
The inspector will question privately a representative number of employees and management
personnel concerning safety and health conditions in the workplace.
Citations:
Following an inspection by the Ohio Department of Commerce, notice of violations issued to the
public employer must be prominently posted at or near the place where the hazard was found.
Protection:
Employees cannot be discharged or otherwise discriminated against in any manner for filing a
complaint in accordance with the Act or by instituting or causing to be instituted any provision of
the Act. Discrimination complaints must be filed with the State Personnel Board of Review within
60 days of the discriminatory act or be pursued through provisions under a collective bargaining
agreement.
