Part II
- GENERAL GUIDELINES FOR WORKING WITH LABORATORY CHEMICALS
1. It is essential to minimize chemical exposure to the greatest extent possible. Because few laboratory
chemicals are without hazards, precautions for handling all chemicals shall be exercised. As a rule, skin
contact with chemicals shall always be avoided.
2. Avoid an underestimation of risk. Exposure to laboratory chemicals shall be minimized even for substances of
no known significant hazard. Special precautions shall be taken for substances with special health hazard
risks. One shall assume that any mixture of substances would be more toxic than either of its single
components alone. One shall also assume that all substances of unknown toxicity are toxic.
3. Adequate ventilation must be provided. The best way to prevent exposure to hazardous substances is to
prevent their escape into the atmosphere by use of fume hoods and other ventilation controls. Containers of
volatile chemicals shall be capped before and after contents are accessed.
4. Chemical storage areas shall be annually inspected for outdated chemical stock and deteriorated, leaking, or
broken containers. Such containers shall be brought to the attention of the CHO and disposed of properly.
All chemical substances that have the potential to become unstable with age shall be disposed at the end of
each school year, regardless of the quantity of each substance in inventory.

When possible, a less hazardous chemical shall be substituted.
The minimum quantity necessary shall be calculated and as close to that amount as possible
shall be purchased.
Particularly hazardous chemicals (highly toxic, carcinogens, reproductive toxins, etc) will not
be used without permission of the Chemical Hygiene Committee and/or the CHO, obtaining
and/or implementing specific engineering and work practice controls and PPE as required by
1910.1450(e)(3)(viii).
The teacher shall complete the Chemical Hazards Preparation Form in Appendix A prior to
each lesson, including safe work practices and emergency procedures, and provide them to the
Chemical Hygiene Committee and/or the Chemical Hygiene Officer for review and approval.
Available PPE shall be evaluated for resistance to the new chemical. If it is not sufficient
either it shall not be purchased or
PPE known to be resistant to the chemical shall be purchased,
the Certification of Hazard Assessment for PPE shall be updated
employees using the new chemical shall be trained in the hazards and PPE.
This shall be completed prior to use of the chemical.
Each individual teacher will be responsible for ordering the chemicals needed to perform their desired
labs;
Where sufficient existing quantities of the chemical are available in the school district the
chemical shall not be purchased.
To avoid duplicate purchasing orders ______ [insert the process by which you will avoid two
teachers, who didn’t talk to each other, buying 1 liter of a chemical each when they only
needed half a liter each. Save money, save space, avoid stockpiling.]
The smallest available quantity that will cover their expected use for the school year shall be
ordered.
Donated chemicals or chemicals from other classrooms in the School District shall be accepted only
after approval is obtained from the Chemical hygiene Officer. It should be established that the
donated chemical is in excellent condition, that an appropriate MSDS is available, and that there is a
specific use for the donated material.
No container will be accepted without a Material Safety Data Sheet and a label clearly identifying at
least the contents by name as it’s found on the MSDS. No container will be accepted if it’s leaking.
Sealed containers, such as for biological specimens, shall be labeled, have an MSDS, and employees
shall be trained in the hazard of the chemicals in the container.
Food items used in experiments shall be clearly marked as “not for food use” and shall have an
MSDS, where possible, for safe storage and use.

shall not be
sent to the (High School Chemistry storage room)
until:
The CHO is notified.
They can be safely stored until disposal.
An MSDS is located or obtained.
[In my inspections I sometimes find that chemicals found in the district, say the middle school science classroom,
suddenly appear on the High School Chemistry Teacher’s desk with the expectation that they will take care of the
problem. The Chemistry Teacher usually does not have time to do more than shove it into the chemical storage area
for future disposal. This can be very unsafe, depending on the contents and chemical status of the chemical.
Use or alter the bullet points above to address this hazard. Fill in the underlined parenthesis with your specific
information.]
Chemicals will be stored in accordance with accepted standards of compatibility. Incompatibles shall
never be stored together. An inventory list arranged alphabetically will be posted in the storage
room. Material Safety Data Sheets will be arranged alphabetically and located in the storage room.
Do not store chemicals, reagents or apparatus on lab bench. Keep shelves organized with labels facing
out.
Should the label become defaced or degraded the reason for this condition shall be identified (student
defacement, poor pouring practices, seepage from under lid due to warm storage conditions) and
corrected where ever possible. A new label and/or method of labeling (such as laminating the label and
attaching by a twist tie, labeling the shelf, or putting clear plastic tape over the label on the bottle) shall
be implemented.

For small spills, 30 ml of hazardous chemical or less, the teacher shall clean up if the perceived risk is low.
1. Notify CHO and have personnel in the area restrict access.
2. If volatile materials are involved ______ shall be notified to go to 100% outside air or turn off the HVAC
to prevent contamination of recycled air.
3. Eliminate all sources of ignition and turn off equipment if it is possible to do so safely.
4. Review the MSDS for the spilled material, or use your knowledge of the hazards of the material to
determine the appropriate level of protection.
5. Wear gloves and protective eyewear. Do not attempt cleanup if you feel unsure of your ability to do so or
if you perceive the risk to be greater than normal laboratory operations. Cover spill with sodium carbonate
or bicarbonate, or material in the spill kit. When reaction stops pickup with damp sponge or paper towels
and put the contaminated absorbent in a labeled hazardous waste container.
6. Spill kits shall be applicable to the hazards and kept stocked by _________.
If greater than 30 ml, or if it will take longer than 15 minutes for you to clean-up,
1. Evacuate students, turn off equipment and take MSDS book with you on the way out.
2. Immediately call CHO at ____or the [Safety Director or whatever you call him/her] at _____ to report
the spill, and help with proper cleanup and disposal procedures.
3. The CHO and teacher shall restrict access to the area.
4. The CHO shall contact the emergency agency ____ will be contacted and qualified response team will be
responsible for the clean up and disposal of hazardous chemicals.
Incident Reporting & Follow-up:
1. Report all occupational injuries or illness to CHO as soon as possible. CHO, SD or laboratory personnel
must document the incidence and file with CHO.
2. Personnel are encouraged to report "near misses" as they are considered a
precursor to actual incidents.
3.
Instructor and CHO are to conduct (or coordinate) an investigation of all incidents and "near
misses." The goal of the investigation is to identify and address any deficiencies in the Standard
Operating Procedures or Chemical Hazard Preparation Form that may have contributed to the
incident and correct/update the CHP to address these issues.
12. INFORMATION AND TRAINING:
Employees will be trained upon initial assignment concerning chemicals available, procedures, location of the
chemical hygiene plan, location of Material Safety Data Sheets, and the Chemical Hygiene Officer will cover
the method of hazard identification with an annual refresher training. Information and Training shall
include the following but not limited to:
A. Components of the Chemical Hygiene Plan:

(such as monitoring conducted by continuous monitoring devices, visual appearance or odor of
hazardous chemicals when being released, etc.)
D. Safe Work Practices:
- The measures employees can take to protect themselves from these hazards, including
specific procedures the CHP has implemented to protect employees from exposure to
hazardous chemicals, such as appropriate work practices, emergency procedures, and
personal protective equipment to be used.
13. WASTE DISPOSAL PROGRAM
Identified Hazardous Waste will be collected, segregated, stored and disposed of in compliance with all current local,
state and federal regulations.
Use MSDS guidelines to determine proper disposal methods.
All containers of hazardous waste must be properly labeled. The waste chemicals must be identified by
their
proper chemical name (not formulas),
include proportions of a mixture.
The label must say “HAZARDOUS WASTE”. The label must be completed before it will be
accepted for disposal by the Safety Director (SD).
Date the waste when it is put into the ________. [insert location for your hazardous waste
containers, ie. Cabinet under fume hood room #]
All waste must be kept in sealed containers at all times, unless you are actively pouring into the
container. Zip-loc bags for dry debris must also be labeled and sealed.
Do not evaporate waste.
Do not mix incompatible wastes. Ensure the waste container is compatible with the waste and use the
appropriately sized container.
Indiscriminate disposal by pouring waste chemicals down the drain or adding them to refuse for landfill
burial or evaporation is unacceptable.
Once a container is full, contact ______ as soon as possible. to arrange for a hazardous waste disposal
pickup through certified waste haulers.
Have and maintain separate containers for trash and broken glass.
Waste disposal method: As written in lesson plans using guidelines above and those found in the
Suggested Disposal Procedures in the current FLINN Catalog and Reference manual found in Room
___ and to be performed.
14. SPECIFIC SAFE WORK PRACTICES BY HAZARD:
[The more information in this section the easier it will be to prepare for future lessons. If you come up with a
particularly good specific safe work practice please ‘share with the class’ and I’ll update this template.]
A. PROCESS: When mixing and handling various concentrations of hazardous materials, minimize
chemical exposure by reducing the amount of time working with them and keeping containers closed
whenever possible.
17
B. HAZARDOUS CHEMICALS/CLASS OF HAZARDOUS CHEMICALS: Substitute low toxicity
chemicals for ones with high toxicity. This enhances personal safety and reduces impact to the
environment in terms of waste disposal. Following are groups of hazards.
* Liquid Corrosives * Solid Corrosives * Volatiles * Reactives:
C. SPECIAL HANDLING PROCEDURES AND STORAGE REQUIREMENTS: One shall
always regard unknowns to be toxic. Any mixture of toxic compounds is presumed to have a synergistic
effect, namely, the toxicity of the whole is greater than the sum of each component.
Any special handling requirements shall be noted on the Chemical Hazards Preparation Form.
Use the guidelines in part D, the MSDS for the chemicals, and hazard information in Appendix A and B of 1910.1200
and the NIOSH Pocket Guide, http://www.cdc.gov/niosh/npg/ to assess the hazards, select the PPE, develop the safe
work practice
s and emergency response procedures, etc. needed to complete the Chemical Hazards Preparation Form
in Appendix A. These procedures will be in addition to the general safe work practices outlined earlier in this Plan.
D. CHEMICAL HAZARD INFORMATION FOR A SPECIFIC COMPOUND: Knowing the hazards of a
chemical and how to properly handle and dispose of these compounds, including during the Pre and Post-Lab
operations, will help prevent harmful and unnecessary exposures.
For all compounds:
Work shall be performed with the smallest possible amount of the chemical or determine if a less hazardous chemical
or process could be used as a replacement.
Containers shall be kept closed as much as possible to reduce potential for spilling and exposure to vapors.
Contaminated gloves shall be removed before using a writing implement to take notes.
High Acute Toxicity, Reproductive Toxins, Carcinogens:
First, try to replace them with less hazardous materials.
Second, use videos or other methods of getting the lesson across.
If that fails then the Laboratory standard requires:
Specific consideration shall be given to the following provisions which shall be included where appropriate:
Establishment of a designated area;
Use of containment devices such as fume hoods or glove boxes;
Procedures for safe removal of contaminated waste; and
Decontamination procedures.
All use of such chemicals shall only be conducted with prior approval of the Chemical Hygiene Committee
and/or the CHO.
Many of these have OSHA Expanded Standards, a standard all their own with specific safe work practices,
medical evaluation, air monitoring, and recordkeeping requirements. These include:

Toxic chemicals that do not meet the level above still must have safe work practices developed based on the
chemicals specific characteristics and hazards.
Can the chemical be absorbed through the skin to cause adverse systemic health effects?
Will the chemical irritate the skin or eyes sufficiently to require safe work practices or PPE?
Can the students take what is before them and make something more hazardous?
Does the chemical have to be cut, introducing a sharps hazard?
Is the chemical so light and fluffy it is easy to inhale or will adhere to gloves, clothing and hands
via static electricity?
Will it generate heat during the lesson?
Will it generate harmful light that requires eye shades?
Will it make a huge, hazardous, difficult to remove mess?
Will it be so smelly it has to be completely used in the hood?
Will the reaction startle the students potentially causing them to trip or drop inconvenient things?
Think each lesson through to find the high hazard points, whether physical or chemical. And then address
them.
Corrosive Solids: Corrosive means a chemical that causes visible destruction of or irreversible alterations in living
tissue by chemical action at the site of contact. Corrosive solids, such as sodium hydroxide and phenol, can cause
burns to the skin and eyes. Dust from corrosive solids can be inhaled and cause irritation or burns to the respiratory
tract. Many corrosive solids, such as potassium hydroxide and sodium hydroxide, can produce considerable heat when
dissolved in water.
The following work practices shall be followed when handling, storing and disposing of corrosive solids:
19
1. Do not bring out the chemical until the class room is calm and set the students up for the least amount of traffic
around the bench work area.
2. Remove all non essential chemicals, books, equipment, etc. from the work area prior to placing the corrosive solid
on the bench.
3. When mixing with water, always slowly add the corrosive solid to water, stirring continuously. Caution, some
water reactive corrosive solids can ‘skitter’ across the surface and may ‘jump’ out of the container.
4. Review the potential hazards from the corrosive solid and from the process to select the engineering and work
practice controls necessary to protect the teacher and students.
a. Where heat is a byproduct of the process the glassware selected shall be heat resistant and heat
resistant gloves that can be worn over the chemical resistant gloves shall be available. Also, any
flammable material not required for the lesson shall be moved away from the work area and the work.
b. If there is a possibility of generating a significant amount of dust, hazardous vapors, volatile reaction
that produces gas, potential for explosion or material bubbling or splashing out of the container then
conduct work in a fume hood.
5. Wear gloves and eye protection when handling corrosive solids. Refer to Appendix F Chemical Inventory for
proper glove choice. Remove, rinse or replace gloves before taking off the eye protection.
6. Waste disposal method: where necessary due to potential hazards, such as generation of heat, corrosive solids shall
be disposed of in segregated, labeled waste.
Corrosive Liquids:
Corrosive liquids (e.g. mineral acids, alkali solutions and some oxidizers) represent a very
significant hazard because skin or eye contact can readily occur from splashes and their effect on human tissue
generally takes place very rapidly. Bromine, sodium hydroxide, sulfuric acid and hydrogen peroxide are examples of
highly corrosive liquids.
The following work practices shall be followed when handling, storing and disposing of Corrosive liquids:
1. The eyes and hands are particularly vulnerable. It is therefore essential that approved eye and face protection be
worn in all laboratories where corrosive chemicals are handled.
2. Gloves and other chemically resistant protective clothing and a lab coat shall be worn to protect against skin
contact. Refer to the gloves in Appendix F Chemical Inventory for proper glove choice and include all PPE in the
Chemical Hazards Preparation Form.
3. To avoid a flash steam explosion due to the large amount of
heat evolved, always add acids or bases to water (and
not the reverse). These mixtures shall be performed in the fume hood. See corrosive solid section for management
of heat hazards.
4. Acids and bases shall be segregated for storage. Nitric Acid shall be isolated in the acid storage cabinet.
5. As with all chemicals, liquid corrosives shall be stored below eye level.
6. Adequate quantities of spill control materials shall be readily available. A spill kit for acids and bases is available
_____________________.
7. Waste disposal method: ensure that the waste container, properly labeled is available and has sufficient space for
the type of corrosive used and the products, including mistakes, of the lesson prior to beginning the preparation
phase.
20
Reactives:
Reactive chemicals are substances that can explode or enter into violent reactions releasing large amounts
of light, heat, and gases. A number of reactive chemicals are recognized explosives, requiring only a mild initiating
force for detonation. Other reactive chemicals are capable of detonation but require a stronger initiating force. Some
reactive chemicals will not detonate but can enter violent reactions producing large quantities of heat and explosive
gases. Reactive chemicals must be handled with extreme care, even milligram quantities of some chemicals can result
in violent explosions.
Classes of Reactives: While almost all chemicals will react with something some chemicals are so reactive that the
reaction can create a hazard. Reactive chemicals are classified as explosives, strong oxidizing or reducing agents, acid
sensitives, water reactives, air reactives, and special organic compounds.
Solid Reactive examples include sodium, potassium and lithium metals; acid anhydrides, acid chlorides and
salt hydrides.
Liquid Reactives are chemicals that react vigorously with moisture, oxygen or other substances. Examples
include organic halides, phosphorous trichloride, titanium tetrachloride, butyl lithium, and hydrazine.
The following work practices shall be followed when handling, storing and disposing of Reactive chemicals:
1. Quantities shall be limited to the amount necessary for the work in progress.
2. Water reactives cannot be stored in the same room with combustible or flammable materials, 1910.106(d)(7)(iii).
3. Safety glasses, face shield, gloves, and a laboratory coat shall be worn at all times when handling, transporting, or
manipulating reactive chemicals.
4. Adequate and appropriate portable fire extinguishers shall be immediately available in the laboratory.
5. Approved eye-wash stations and emergency showers must be in working order. Safety shields shall be used as
necessary.
6. Prior to bringing the chemical from the storage area the work bench shall be cleared of all materials not
immediately required for the lesson or process.
7. Explosives shall be protected from heat and shock and shall be purchased or made immediately prior to the class
and thoroughly disposed of properly afterwards.
8. Clean up spills immediately. The safest method is to absorb the material onto vermiculite or a similar loose
absorbent. Verify they absorbent material is compatible and will be effective before the prep for the lesson and
include the specific spill method in the Chemical Hazards Preparation Form.
9. Waste disposal method: prior to use of the chemical the method for disposal shall be prepared to ensure it is not
added to a waste container with materials it will react to and that in the future such chemicals shall not be added
to the container the reactive chemical is in. The waste container shall immediately be labeled as to its contents to
reduce such a problem in the future.
Volatile Chemicals
: Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs
include a variety of chemicals, some of which may have short- and long-term adverse health effects. (examples:
hexanes, acetone, methylene chloride, diethyl ether)
The following work practices shall be followed when handling, storing and disposing of Volatile chemicals:
21
1. The potential for absorption through the skin with adverse health effects shall be carefully evaluated and special
attention shall be paid to glove selection.
2. Any part of the process that could cause splashing to the arms or body shall be evaluated and engineering and work
practice controls developed and noted on the Chemical Hazard Preparation Form.
3. Work areas shall be cleared of anything that produces a spark or flame.
4. Highly flammable volatiles that could ignite with static electricity sparks are discouraged from purchase or use but
if they are then the Form should include the steps that will be taken to ensure the safest environment possible. [no
sweaters, means for grounding the body before touching containers or equipment, sneakers, etc.]
5. No more than 10 gallons of flammable and combustible liquids, combined, shall be stored outside of a flammable
storage cabinet unless safety cans are used. When safety cans are used, up to 25 gallons may be stored without
using a flammable storage cabinet. Every effort shall be made to have no where near that quantity of material
on hand. [have a garage sale if you need to]
6. Prior to working with volatiles be sure fume hood is in working order and has sufficient room for the equipment,
materials, and motion required for the process.
7. Work in the fume hood to ensure proper ventilation when working with volatile chemicals.
8. When carrying volatile chemicals through the lab, carry them in a covered container and the bottle or container
shall be capped, closed, etc.
9. Work with smallest amounts possible and keep containers closed or covered as much as possible to minimize the
amount of volatile gases into the room.
10. Waste disposal method: As written in lessons plan and to be performed in compliance with the CHP and all current
local, state and federal regulations.
22
Appendix A. Preparation for Hazards of working with Chemicals.
Use the following Form when preparing for a laboratory procedure that involves the use of hazardous chemicals and
attach to the lesson plans. Focus on procedures found in the CHP, along with the information you can find on line, in
Appendix A and B of the Hazard Communication standard, 1910.1000 and the MSDS provided with the chemicals to
develop safe work practices in the laboratory.
Never underestimate the hazards associated with the laboratory. If you are unsure about what you are doing, get
assistance. Do not use unfamiliar chemicals, equipment, or procedures alone.
Know incompatibilities of the chemicals involved.
Replace highly hazardous chem
icals with those with lower hazards whenever possible.
IMPORTANT:
The five prudent practices of chemical safety sum up these safety guidelines:
1. Treat all chemicals as if they were hazardous.
2. Minimize your exposure to any chemical.
3. Avoid repeated exposure to any chemical.
4. Never underestimate the potential hazard of any chemical or combination of chemicals.
5. Assume that a mixture or reaction product is more hazardous than any component or reactant.
When using chemicals during a lab, the teacher will follow guidelines provided in the Chemical Hazards Preparation
Form developed from the MSDS and ensure all PPE and engineering controls required are provided and in working
order prior to starting the preparation phase of the procedure.
This Form shall be completed and attached to each lesson plan for implementation.
First select all on the next page, copy and paste to a separate document. When complete store with the Chemical
Hygiene Plan for future use.

Appendix G. Glove Selection
Some Common Sense Rules for Glove Selection:
First, do you need gloves: is the hazard a manageable irritant or will it absorb and cause sterility
and/or deafness (Carbon Disulfide)
Second, evaluate the conditions of use, will there be splashes, mists, droplets, sharp objects, heat, etc.
Third, consult the relevant MSDS which may recommend a particular material but usually the
chemi
cal manufacturer will not take the liability.
Fourth, if the MSDS says “chemical resistant” or glove material but no thickness then contact your
glove manufacturer and ask if you can fax MSDS and get advice on which of their products will work
best for the largest number of chemicals that you have, include double gloving as an option
Note the glove selection by material and thickness (in case you find a cheaper provider or the
manufacturer stops making “Whizbang Glove #3”)
Select gloves of the correct size and fitting to reduce likelihood of tearing or interference with
dexterity.
The hazard assessment shall be done in compliance with the OSHA standard on general requirements for
personal protective equipment (29 CFR 1910.132). Glove Selection shall be specific to the hazard, the tasks
being performed, and in compliance with the OSHA standard on hand protection (29 CFR 1910.138).
The result of the hazard assessment will be noted on the inventory.
Some Common Sense Rules for Glove Use:
Before use inspect gloves for physical damage and check for expiration date.
When the process creates splashes either change the procedure, rinse the external surface frequently
with water, or change gloves frequently.
Remove gloves when tears or punctures are observed.
Remove gloves in a way that avoids the contaminated exterior contacting the skin. Dispose of
contaminated gloves properly. Do NOT
reuse gloves.
Check your hands and wrists for redness or discoloration indicating exposure after removal of gloves.
Wash hands after removing gloves.
ALWAYS, ALWAYS, ALWAYS, remove your gloves when you turn away from the bench. If your
project requires writing down information the following options may be used:
o Dictate notes to a classmate or student
o Remove gloves, write notes on a surface other than the work bench, then put on new gloves
o Have a dedicated white board and marker that remains on the bench, transcribe later
31
Appendix H Biology Laboratory Safety
Safety and Health Hazards specific to the Biology labs include:
Dissection of specimens preserved in very dilute formaldehyde with sharp implements
Handling live specimens
Handling Dissecting Instruments and Preserved Specimens
1. Preserved specimens showing any signs of decay should not be used for any type of lab observation or
dissection.
2. Disecting instruments, such as scisors and scalpels, are very sharp. Always use a cutting motion directed
away from yourself.
3. In performing a dissection make sure the specimen is pinned down firmly in a dissecting tray before
beginning work.
4. Use your instruments with care. In general, very little force is necessary for making incisions. Excess
force will most likely damage delicate tissues.
5. Never touch your eyes while handling preserved specimens. Wash hands thoroughly with soap and water
after working with specimens.
6. Order the minimum number of specimens and discard, with preservative solution, at end of use.
7. Identify the hazards of the preservative solution used for the specimens and develop work practice
controls, provide engineering, and/or PPE prior to obtaining the specimen
Handling Living Specimens
1. Understand clearly the purpose and procedure of the activity before you begin work.
2. Animals should be handled gently so as not to produce undue excitement or trauma.
3. Avoid subjecting specimens to stressful conditions such as exhaustive exercise or painful stimuli.
4. Where there is potential for biting leather gloves shall be worn.
5. Identify any hazard presented by the live specimen: such as toxoplasmosis from cat litter dust, venom,
allergens, etc. and develop work practice controls, provide engineering, and/or PPE prior to obtaining the
specimen
