Chemical Hygiene Plan
l The 2010 (revised) New Trier Science
Department Chemical Hygiene & Safety
Plan is the document that outlines our
department safety program.
l The complete CHP is accessible in the
Science Shared Drive (G:) under
“Chemical Hygiene & Safety.”

What To Look For…
l There are Safety binders in the First
Aid cabinet of each room that lists
location and operation of safety
equipment in that room, and
emergency procedures.
l Safety signage in each room. Is there
something that needs replacement
l Safety check routines are established
and you will be asked to check on
certain items each month.

What To Do…
l Two lab rules that apply to the science
department:
– No food in laboratories. Re-sealable
beverage containers are permitted only in
the classroom section of the room.
– Students who have no scheduled lunch
periods should make arrangements with
other teachers.
– Friday Advisery periods are a special case:
use tablecloths provided and eat only in
the classroom section. Clean up all food
residue prior to 1 st period.

Where Is Safety Information
l We have a Safety File Cabinet in the
Science Office (173 at Winnetka) that
contains other safety resources. It is
near the doorway between 173 and 136.
l The MSDS volumes are still near the
entrance to the department in 173 for
quick access in case of an emergency.

MSDS and Health Services
l Health Services requests that we have in
our possession, during each laboratory
experiment, paper copies of the MSDS’s.
Timely medical treatment is essential,
and having MSDS copies immediately
available in the lab room which outline
specific treatments will provide medical
personnel the information they need.
These copies can be kept in your folder or
lesson plans so they can be retrieved
immediately upon an accident occurring.

Chemical Inventory & Storage

Organization of Chemicals
• The Flinn Scientific system of labeling
chemicals and shelving is used
throughout the department.
• The system separates chemicals into
groups (I#1, I#2, O#1, etc.) that do not
react with each other. Groups that do
react with each other are then physically
separated in the storage rooms.

Where’s s Waldo
l
l
l
l
Refer to the Flinn catalog for the group
designation.
Familiarize yourself with the storerooms.
Ask for help in locating chemicals.
A current inventory is on our Science Shared
drive (G drive) under “Chemical Hygiene &
Safety.”

Designated Chemical Storage
Winnetka
l 164a Inorganics
l 161a Organics and Indicators; Inorganics for use by teachers
in adjacent rooms
l Household chemicals – stored in most prep rooms
l Basement - Liquid Overstock
l All storage rooms and labs may also contain commonly used
chemicals and chemicals in lab setups
l Two locked poison cabinets in 161a & 164a
l Radioactive samples are in a file cabinet in 164a. Please
keep radioactive samples in the bottom drawer, and
detectors in the top drawer.
Northfield
l 2 central storerooms on the 2 nd and 3 rd floors

Extremely Hazardous Materials
While all chemicals have the potential to be
hazardous, the following categories of
chemicals are considered extremely hazardous.
No materials should be used unless the
educational value outweighs the risk. Always
overestimate the dangers of chemicals.
l Explosives - e.g., Ethyl Ether
l Poisons - e.g., Bromine
l Carcinogens - e.g., Cadmium & Cd salts
l Caustics - e.g., Concentrated Acids
l Flammables - e.g., Sodium (metal)
l Irritants - e.g., Butyric Acid

Chemical Disposal
l Check Flinn Catalog for appropriate
disposal if a substance cannot be
neutralized.
l Collect hazardous waste and label with
“Discard” sheet: chemical names, your
name, and date – Ask for information
and/or disposal help.
l Waste is removed usually every other
year with PPS and Art Department waste

Summary
l Read MSDS before handling chemicals.
l Have MSDS in lab
l Teach students how to read labels.
l Learn Flinn storage.

Equipment Use & Safety
l Maintain equipment by inspecting
cords, moving parts, etc.
l Identify with your name and tag broken
equipment
l Notify Science Lab Supervisor or PPS
for repair.

Fire Safety
l Think safety for people first!!!
l Evacuate the area
l Notify the fire department (Dial 911 or
PPS or pull box if necessary)
l Small fires: use fire extinguishers
l On people: use fire blankets

Fire Extinguishers
l
l
l
Our labs contain ABC Dry Chemical
extinguishers.
ABC or Multi-Purpose extinguisher utilize a
specially fluidized and siliconized mono
ammonium phosphate dry chemical.
– It chemically insulates Class A fires by melting at
approximately 350°F and coats the surface to which
it is applied.
– It smothers and breaks the chain reaction of Class B
fires and will not conduct electricity back to the
operator.
If you are working with burning metals, a Class
D (164a) or bucket of sand should be in your
lab.

Using a Fire Extinguisher
l Remember PASS
–Pull the pin
–Aim at the base of the fire
–Squeeze the lever slowly
–Sweep from side to side

How to Use a Fire Extinguisher
Pull the pin…
This will allow
you to
discharge the
extinguisher

How to Use a Fire Extinguisher
Aim at the base of the fire…
Hit the fuel.
If you aim at
the flames...
… the extinguishing agent will fly right
through and do no good.
Environmental Health & Safety Dept.

How to Use a Fire Extinguisher
Squeeze the top handle…
This depresses a
button that
releases the
pressurized
extinguishing
agent.
Environmental Health & Safety Dept.

How to Use a Fire Extinguisher
Sweep from side to side…
.. until the fire is
completely out.
Start using the extinguisher
from a safe distance away,
then slowly move forward.
Once the fire is out, keep an eye on the area in case
it re-ignites.

First Aid
l You are responsible to provide aid to
the level of your training. For example,
if you are CPR certified you are
expected to use your talents.
l If there is blood, be sure to contact the
nurse and/or send the student to
Health Services. Use the phone in the
lab.
l First aid cabinets are in all labs – check
for supplies regularly. (e.g., the Quik-
Chlor Kit and Band aids)

Reminders
l You are a science educator and
professional who is responsible to look
up and determine safety risks for
yourself and your students.
l If you do not know something, ask
questions and research answers

Sign Off
l By completing this process online you
will sign off as having completed this
year’s safety training
l Throughout the year you will receive
safety information during department
meetings that you are expected to read.
If you have any questions or concerns
please talk to Elaine, Mary Beth, Nicole,
Robyn, or Gerry.
