
Implement and follow a safety program

Provide a safe working and learning environment

Permissible Exposure Limit (PEL) is the maximum amount
or concentration of a chemical that a worker may be
exposed to under OSHA regulations. The higher the PEL the
better.
 Threshold Limit Values (TLVs) are guidelines (not
standards) that reflect the level of exposure that the typical
worker can experience without an unreasonable risk of
disease or injury
 Time-Weighted Average (TWA) is an average value of
exposure over the course of an 8-hour work shift

Acute
Chronic
Generally manifests quickly
(either immediately or
within days after an
exposure).
An example would be an
acid spill on skin. The
acute effect is immediate
irritation or corrosion of
the skin.
Usually takes longer to
develop through repeated
exposures.
Usually targets certain
organs (i.e. asbestos
targets the lungs).
An individual may not be
able to sense the
exposure.

If the label is not the original from the manufacturer,
it must Include:
 Identity of Product (no chemical symbols)
 Hazard Warning
 Date of Purchase
Types of Containers
 Original (from manufacturer)
 Secondary (dilutions, etc.) – Label these containers accurately!

Why PPE?
It’s the last line of defense between you and
the hazardous chemical
What types are required?
- Goggles and Face Shields
- Gloves (disposable – chemical – heat)
- Aprons
Instruct students on purpose and proper use
Lead by example!

Responsibility of instructor to obtain MSDSs for new
products received
Are MSDSs part of your
curriculum?
Do you follow the
guidelines on MSDSs?
Would you know how to
find an MSDS during an
emergency situation?

are above waist-height
 Those who are trained may use fire
extinguishers but…
your safety and the safety of your student’s
is your first priority!
© IEA, Inc.

Assess spill. If chemicals are unknown, evacuate area.
Call emergency personnel if your safety is in danger or
the spill is too large to handle yourself.

Contact fire department if contents are greater than one
gallon.

Extinguish all sources of ignition if chemical is flammable
and turn off the main gas shut-off valve.

Immediately attend to splashes in eye or on skin by using
eyewash or drench shower.

Direct First Aid needs to the school nurse.
© IEA, Inc.
Use appropriate
personal protective equipment!!!!

Use appropriate spill neutralizer from spill kit (acid
or base). Follow instructions on box.

Use the polypropylene broom and dust pan
provided with neutralizer kit to sweep up materials.
Dispose of according to hazardous waste rules and
regulations (if applicable).

If a release of any substance may cause pollution of
the air, land or water, report the incident
immediately to the district Environmental Health &
Safety office. The district is required to notify the
Minnesota Duty Officer (within 24 hours) at:
 (651) 649-5451 - Metro
 (800) 422-0798 - Greater Minnesota


For specks of dust or dirt in the eye, do not rub the
eye because this can cause scratches and abrasions.
Use eyewash and continue flushing the eye. If the
speck does not wash out or pain and redness
persists, see an eye doctor.

For a blow or impact to the eye, apply a cold
compress. Do not apply pressure. See a doctor
immediately if there is continued pain, blood in the
eye or any visual disturbance. This could be the sign
of internal eye damage.
© IEA, Inc.

For objects stuck in the eye or punctures to the
eye, do not try to remove the object from the eye
and do not use eyewash. See a doctor
immediately.

For chemical burns, open the eye as wide as
possible and immediately flush the eye with water.
Continue flushing the eye for at least fifteen
minutes. If possible, continue flushing the eye
while in route to the doctor or hospital. The
flushing fluid should be tepid or lukewarm. A
doctor should be seen immediately.
© IEA, Inc.
Emergency Eyewashes & Showers require weekly Inspections
which must be documented on the inspection tag

All plumbed eyewashes must be flushed for 3 minutes
weekly

Plumbed showers should be flushed briefly on occasion
(monthly) to ensure proper function

Portable eyewashes require weekly inspections (follow
manufacturers instructions)

All units must be accessible, clearly marked, clean, and
nozzle covers must be in place
© IEA, Inc.

Ensure that the fire extinguisher is accessible.


Are any materials blocking the fire extinguisher?
Is it visible from all points in the room?
▪
If not, is there proper demarcation above the fire extinguisher?

Is the fire extinguisher properly mounted in the cabinet or on
the wall?

Is the pressure indicator in the ‘green’?

Tap the pressure indicator to ensure it is functional.

Has the fire extinguisher been vandalized in any way to
comprise its function?

Be sure to initial and date the inspection tag at time of
inspection.

Globally Harmonized System (GHS) for
standardizing and harmonizing the classification
and labeling of chemicals.
 Goal to ensure employers, employees and the public
are provided with adequate, practical, reliable, and
comprehendible information on hazardous
chemicals
 Allow for appropriate protective measures for health
and safety
© IEA, Inc.
To have a common worldwide approach to
classifying and communicating chemical hazards.
 Harmonized definition of hazards
 Specific criteria for labels
 Harmonized format for safety data sheets (SDS)
formerly called material safety data sheets (MSDS)
© IEA, Inc.

The idea is that the same criteria will be used
all over the world to determine if a material is
flammable, toxic, corrosive, etc.

To avoid classifying the same product as
hazardous or non-hazardous, depending on
which classification system is used
For example, a product may be considered
flammable or toxic in one country, but not in another
to which it is being shipped
© IEA, Inc.

Adopted by Federal OSHA on March 26, 2012,
with an effective date of May 25, 2012


to adopt the revised 1910.1200 standard
(HazCom), on May 21, 2012

MNOSHA published this intent on July 2, 2012
in the State Register
