Safety Training

Spring ISD, 2015-16
Implement safe practices to protect students and adults in Spring ISD labs and classrooms each day.
Communicate district, state, and federal laws and best practices concerning safety.
Fulfill yearly safety training requirement.
Provide you with the knowledge and resources you need to protect yourself from accidents, injury and potential legal liability.
"Duty of Care"

Instruct & Warn


Provide a Safe Environment

Age & Maturity of students
Usefulness of the activity compared to its hazards
Could the activity be made safer with different procedures or equipment?
While watching, take note: What aspect(s) of duty of care were breached?
Provide Adequate Instructions
Provide safety information
Fully instruct before students do the lab
Consider a pre-lab activity
Consider conducting a full demonstration before allowing students to do the lab

Warn Students of Possible Dangers
Provide Adequate Supervision
"Adequate" supervision doesn’t necessarily mean CONSTANT supervision.
A Judge will determine what is “adequate” based on the classroom conditions: age of students, classroom, hazards involved, etc.
Duty to Provide Safe Facilities and Equipment
Why does the teacher have this responsibility? Because YOU are the professional in the room: YOU make the final decision about what would be safe IN YOUR FACILITY.
This duty applies to ANY teacher, even if an English teacher teaches in a Science Lab - that English teacher is responsible to be sure all the chemicals, equipment and facilities are secure!
Maintain Lab Equipment
It is the teacher's duty to FIX, REPAIR or REMOVE extra, damaged, or unusable materials
Includes things like broken goggles, lab aprons and other protective equipment.
What is safety?
Safety isn't just about wearing safety goggles or knowing what to do in an accident...
The first thing that should come to mind when you think about safety is
"How can I
eliminate hazards
within our
everyday procedures and practices

Personal Protective Equipment (PPE)
Safe Storage &
Handling of Chemicals

Accident & Emergency
Equipment Maintenance & Care
for chips, cracks and deep scratches - they compromise the stability of glass. Even Pyrex can shatter under dramatic temperature changes if there are imperfections in the glass.

Be sure you have a place and the materials
necessary (dish soap, bottle brush, sponge,
drying rack, etc) to properly
wash and dry
lab ware

Inspect all
cords, plugs and hoses
letting students use any electrical or gas
If you see scorching, charring,
sparking, frayed cords, or if you feel
excessive heat, that is an indication of a
serious electrical hazard!
Chemical Inventory
(Material) Safety Data Sheets (now just SDS)
Secondary Container Labels
Chemical Storage
Microscale Labs
Chemical Disposal
Goggles are required
to be worn due to:
The use of
hazardous chemicals
The use of
liquids or solids;
The use of
molten materials
Performing grinding, chipping, or other hazardous activities where there is
danger of flying particles
Milling, sawing, turning, shaping, cutting, or stamping of any solid materials;
Heat treatment, tempering, or kiln firing of any metal or other materials;
Cutting, welding, or brazing operations;
use of hazardous radiation
, including the use of infrared and ultraviolet light or lasers;
Repair or servicing of any vehicle; or
Any process or activity
in a vocational, art, industrial arts or science course or laboratory
that might have a tendency to cause damage to the eyes
If you never use another piece of safety equipment - PLEASE remember the importance of goggles. In fact,
goggles are the ONLY personal protective equipment with SPECIFIC LAWS mandating their use
when students' eyes are in danger.

are responsible for making sure students wear goggles in a lab environment!
Maintain Goggles by sanitizing using a UV goggle cabinet
- or -
By spraying with Quat 256 and allowing them to dry completely.

(Quat 256 should be available from custodial staff - ask nicely!)
Maintain aprons by wiping clean after use, untying strings and folding neatly for the next user.

Do not use an apron that cannot be properly secured around the student. Strings should be reattached by sewing if necessary.
There should be a
chemical inventory kept for the entire school
, maintained by your school's safety officer. All teachers (not just science) are responsible for keeping the school's chemical inventory list up-to-date by reporting any new substances to the safety officer and providing an SDS sheet for that substance.

Science labs and prep areas must EACH have their OWN, INDIVIDUAL chemical inventory.
That means that any place where chemicals are stored regularly must have a list of chemicals currently being stored in that location. This list is
maintained by the science teacher(s) in charge
of the classroom, prep or storage room (as assigned by physical classroom location, or by Department Chair or Administrator).
Chemical Inventory:
A list of ALL chemicals kept or used in a particular area.
An industry-standardized report written for different substances or chemicals providing in depth information about health/safety hazards, shelf-life, disposal and emergency treatment of exposure to the substance/chemical.
SDS are REQUIRED to be kept on file for every substance/chemical stored in the prep/storage room and used in demonstrations, activities and experiments.
Providing students, adults and/or emergency personnel with the SDS for substances used/stored within your classroom/lab is the
science teacher's responsibility

One way to keep SDS on-hand to satisfy this requirement is to create an SDS binder for every classroom containing the SDS for all possible substances used in the science classrooms in the school. (Meaning, even though there may be different substances stored in different labs, every lab can have the same SDS notebook - as long as ALL chemicals IN THAT ROOM are represented with current SDS)

Maintaining SDS in your lab is YOUR responsibility as the science teacher
, but it can be made easier if everyone in your department helps create one binder, and you distribute copies, adding new SDS as new substances are brought into the school.
should be stored in a dedicated
Acids cabinet


should be stored in a dedicated
Flammables cabinet

other chemicals should be stored
by chemical family
on shelves with a minimum of 3" of space between chemical families (or if space is limited, you may place them next to each other, separated by a physical divider).

For more information, see the "Chemical Inventory and Storage" section of the Flinn Chemical Catalog and Reference Manual.
When dividing chemicals up for use in class or to share with other teachers, you remove the chemical from the original container (with all its hazard warnings and information), and place it into a secondary container.
You are now responsible for labeling the secondary container to identify its contents and hazards.
Secondary Container Labeling
Secondary Containers MUST be labeled with:
Product Identifier
- Name of the chemical
Signal Word
- Danger / Warning / (none)
Hazard Warning
- Entire statement including all original hazard warnings as on original label
Precautionary Statement
- How do you keep yourself safe during storage and handling?
Minimize risks of chemical exposure by using very small amounts of chemicals.
Instead of 100 mL of a chemical in a beaker, consider using 10 mL in a test tube, or even 1 mL in a drop plate
Hot Hands
" or insulated gloves for working with heat.
Nitrile gloves

for most chemical hazards (although you should check for reactions between nitrile and chemicals before use).
Latex is a known allergen for many!
Standard protective
work gloves

(as you might find at Home Depot) for abrasion hazards.
Other equipment may be available, but if a lab requires more than goggles, aprons and gloves, it probably shouldn't be attempted in a regular school setting...

Note: it is Spring ISD policy that science teachers and students should not conduct activities and labs that require use of a respirator.
If you need a respirator, it's TOO DANGEROUS for a regular classroom!
Exposure to Chemicals
Check SDS for proper clean up procedures.

Keep sand
and kitty litter
on hand for
clean up.
Check SDS for proper procedure

(TYPICALLY you flush exposed areas with water for 15+ minutes - but not always!
Know exposure procedures for all
the chemicals you’re using before
starting a lab by checking the
Be aware of what chemicals are stored in your lab/prep area.
Avoid storing reactive chemicals near each other
by following chemical storage guidelines (For more information check the “Chemical Inventory and Storage" section of the Flinn Chemical Catalog and Reference Manual.)

Keep sparks/flames away from chemical storage areas.

Even without sparks or flames - chemicals can explode if pressure builds up inside a sealed container - often due to degrading chemicals stored well beyond their shelf life.

All students OUT!

If the fire is
smaller than a typical trash can
, you MAY consider putting it out with a

fire extinguisher
or smothering with a
fire blanket

If you do not know how to use an extinguisher or fire blanket, or if you're uncomfortable with this -

If the fire refuses to go
out, spreads, or is too large, just
Using an Extinguisher:
- pull the pin
- aim at the base
- squeeze the handle
- sweep side to side
In case of injury, your action depends upon the severity of the injury. You might:
Send the student to the nurse
Call the nurse to come to your room
words like "unconscious," "bleeding," and "student" or "teacher" when you call.
Call "6-911" from a district phone
This keeps the call within the district emergency system, so ambulances aren't followed by news trucks.
Call "911" if necessary
Where is your lab's
gas / water / electricity cut-off
Lab Equipment Safety Check
Where is your
goggle cabinet
? Does it work? Is there a lightbulb?
Where is your eyewash station?
It should be tested once EVERY SIX-WEEKS.
When was the last time you tested it?
In your classroom/lab, it is
your responsibility
to test the eyewash once every 6-weeks and be sure it is capable of flushing someone's eyes for a minimum of 15 minutes with clean, lukewarm water.
Where is your
safety shower
It should be tested once EVERY SEMESTER.
When was the last time you tested it?
In your classroom/lab, it is
your responsibility
to test the safety shower once a semester to assure it can flush away chemicals in case of accidental exposure.
Do your
safety shower
both have tags indicating the last time you've tested them?
(You can make a tag out of an index card and zip-tie it to the pipe - just record the date it was tested and who completed the test.)
Are your
safety shower
both marked with large, clear signs describing what they are and how to use them?
Where is your
fire extinguisher
fire blanket
Are they both mounted on the wall (preferably on opposite sides of the lab), marked clearly with large signs?
Do you have a
vent hood
? Be sure nothing is stored inside, even if you do not use the vent hood to conduct experiments.

(Sometimes the vent hood is built in as part of the room's air circulation system, and should be kept clear and accessible.)
Do you have a
broken glass container

You can purchase these from Flinn or other suppliers, but it is not necessary. You can use any sturdy container with a sturdy lid that may be closed and taped shut for disposal when it is full.
Suggestions include large coffee cans and Xerox paper boxes.

Mark the box VERY CLEARLY with the words "Broken Glass" and be sure there is no place for broken glass to get out of the container when it is securely closed
(regular boxes often have a gap at the bottom that would allow small pieces to fall out).
When the box is full, tape it completely closed and contact your safety officer to arrange disposal.
Have you posted
Because sometimes good judgement comes with age.
Spring ISD Science
Department Policies

Before participating in any lab activities, ALL students must:
Review safe practices and safety procedures
Return a completed Safety Contract with student and parent signatures
Complete the appropriate grade level district safety test with a score of
Students who do not get 100% on the first administration of the safety test must complete corrections and demonstrate mastery of safe practices and safety procedures.

Ultimately it boils down to this:

You are the adult in the classroom.
You are responsible for the safety of that room.

If something is wrong YOU are responsible for REPORTING it and mitigating hazards to the best of your ability.
So where can you go for help?

The standards for safety changed as of June 2013. The changes are minor for science teachers, and you probably will not notice much of a difference. The new system is called the
Global Harmonized System (GHS)
approach to safety regulations. This approach allows for consistency across international boundaries, and should foster better understanding of hazards.
In public schools, the biggest change that is likely to affect you is the change from MSDS (which are often laid out differently from one manufacturer to the next) to an industry standard
"Safety Data Sheet" (SDS)
. The new SDS will hold the same kind of information, but in a regular format. There are also new standardized
hazard symbols
, or pictograms, which should make identifying hazards faster and easier than ever.

What are the signal words, and what do they mean?
What are the 9 pictograms, and what do they mean? Which are
and which are
hazard warnings?
How many sections are on the SDS? What kinds of information do they contain?
What is an LD-50? LC-50?
Please don't stand on chairs or tables...
Please use real ladders and stepladders if needed.

These general safe practices create a
culture of safety
, and a sense of being "in charge" of your classroom.

This is especially important in an environment where students are
exposed to hazards
, like a science lab!
Does each pictogram mainly represent...
Corrosive substances pose both a clear danger to your health and your physical surroundings, so they are considered both a physical and health hazard
The "environmentally damaging" label is considered optional in the United States. It may not be on substances, even if they have been identified as harmful for the environment.

Your safety is important too!
It doesn't take a lot of weight to hurt you! Lift objects with your knees, keeping the weight as close to your body as possible.
Never try to lift more than 1/3 your body weight, 50 lbs, or more than you're comfortable with
(whichever is less)
Use equipment to assist, or ask for an adult for help with a "team lift!"
household or consumer-grade chemicals
that are used in science demonstrations and labs should be properly stored and handled.
Some household chemicals commonly used in classrooms
are hazardous
require SDS
on-hand if they are stored or used in the classroom.
