SITE SPECIFIC INFORMATION ON CHEMICAL RECEIVING,
STORING OR DISPENSING
(if applicable)
Give the location of your laboratory's chemical receiving, storage or
dispensing area. Describe any ordering policies or procedures for
hazardous chemicals. List any chemicals that require Principal Investigator
approval prior to purchase.
Receiving area(s):
Storage Area(s):
Special Dispensing Area(s):
The following materials require approval by prior
to ordering:
1. any regulated or known chemical carcinogen (section IX of the Laboratory Safety Guide
[LSG]);
2. any highly toxic material (in any physical state) and reproductive toxins (see Sec. XIII
and XIV);
3. any Drug Enforcement Administration controlled substance or precursor thereof.
NOTIFY GROUP INVENTORY MANAGER OF ALL
NEW CHEMICAL PURCHASES TO ENABLE UPDATING CHEMICAL
INVENTORY.
ORDERING AND ACQUISITION OF CHEMICALS
1. Group members should check for the availability of chemicals within the laboratory, or
other campus sources prior to ordering, especially when trial syntheses or special
operations/procedures are being evaluated. For high volume materials such as acetone
check with EH&S Material Handling Facility for recycled/redistilled solvents
2. A barcode should be applied to new containers received in the laboratory and the
computer based inventory should be updated to reflect receipt of the material.
3. Group members should contribute unused/uncontaminated chemicals to EH&S if it is
clear that further use of these particular chemicals within the group is very unlikely.
4. Order quantities of materials appropriate to intended uses. Order minimum practical
quantity of highly toxic and carcinogenic materials. Order time-sensitive materials with 6
month supply as an upper limit. These would include peroxide forming materials and
corrosive compressed gases. Examples of peroxide formers include; isopropyl and diethyl
ethers, 1,4 dioxane, tetrahydofuran, potassium metal. Examples of corrosive gases
include: silanes, hydrogen bromide, hydrogen fluoride, fluorine, hydrogen chloride,
ammonia.
STORAGE AND MAINTENANCE OF CHEMICALS
1) All hazardous material containers require examination at least annually. Chemicals
and their containers should be examined for signs of deterioration and label deterioration.
2) Chemicals should be divided and stored according to compatibility classes so that
accidental mixing between compatibility classes can reasonably be expected not to occur
(i.e. during earthquakes). Chemicals should be stored on shelves with lips or other
restraint. Shelf units should be secured to the wall. See Appendix I
3) Minimize quantities of flammable and combustible liquids stored in the open room.
Flammable and combustible liquids should be stored in Flammable Liquid Storage
Cabinets. If space is limited in flammable storage cabinets, avoid the practice of storing
nonflammable compatible liquids (eg. carbon tetrachloride) and reserve the space in the
flammable cabinet for flammable liquids.
4) Highly toxic/carcinogenic materials should be securely stored in a closed cabinet or
other isolated area where accidental contact or breakage will be prevented. Minimize
quantities on hand. Order smallest practical quantity available.
5) Water reactive materials should be stored away from potential contact with water, i.e.
do not store underneath the sink.
6) All Class 1A flammable liquids, such as diethyl ether, should be transferred in a fume
hood free of know ignition sources to 1 or 2 gallon or smaller safety cans for use in the
lab. 5 gallon drums must be stored in and approved flammable liquid storage cabinet or
storage room.
7) Every group member is responsible for proper labelling, storage and disposal of
materials and synthesized compounds in their work area(s).
8) Prior to leaving (permanently), a group member is responsible for clearing his/her work
area(s) along and proper disposition of all chemicals/materials to storage, waste, or to
another person's control (with their knowledge and agreement). All such materials must
be properly and fully labeled, a special emphasis shall be placed on laboratory
synthesized or non-commercial materials.
9) Cylinders should be separated according to compatibility class and stored chained or
strapped to a fixed surface. Two points of attachment should be used for securing
cylinders if possible. Cylinders should be turned off at the cylinder valve when not in use
and should be capped when stored.
10) Gas cylinders which are used to contain corrosive (or unstable) gases or liquids (such
as fluorine, nitrogen tetroxide, vinyl bromide, or hydrogen chloride) should always be
returned to the distributor within 6 months of the fill date indicated on the cylinder tag.
11) Group members should "date" time-sensitive materials upon receipt and upon
opening. Time-sensitive materials shall be marked with a tag to make them easily
identified. No materials should be used or tested after the manufacturers' "expiration
date" dates unless evidence of current stability has been obtained via direct testing prior
to the expiration date. NOTE: If material is very old (> 1yrs. past label expiration date) or
shows evidence of conversion to a hazardous status (ie. crystalline materials in/under cap
of ethers) then minimize handling and DO NOT OPEN OR ATTEMPT TO TEST - FAX
or email EHS Waste disposal to request a special disposal for this item. Isolate from
possible inadvertent use until picked up. If tested (time frame for testing is based on the
nature of the material) the results must be indicated on container/tag with test date, test
results/method, and initials of (authorized) person conducting test. Examples (see also:
next page) of such materials would be peroxide forming chemicals (such as ethers),
materials which might polymerize or oxidize over time, materials which might become less
stable with dehydration (such as picric acid or perchloric acid).
Peroxide Detection Tests: The following tests will detect most peroxy compounds and all
hyperperoxides: NOTE: these tests should not be used for testing materials potentially
contaminated with inorganic peroxides (i.e. potassium)
Option 1. Add 1-3 ml of the liquid to be tested to an equal volume of acetic acid, add a
few drops of 5% potassium iodide (KI) solution and shake. The appearance of a yellow to
brown color indicates the presence of peroxides.
Option 2. Addition of 1 ml of a freshly prepared 10% KI and 10 ml of an organic
solution in a 25 ml glass cylinder should produce a yellow color if peroxides are present.
Option 3. Add 0.5 ml of the liquid to be tested to a mixture of 1 ml of 10% KI solution
and 0.5 ml of dilute hydrochloric acid to which a few drops of starch have been added
just before the test. The presence of a blue-black color within a minute indicates the
presence of peroxides.
Option 4. Peroxide test strips that turn an indicatative color in the presence of
peroxides. Care must be taken to follow manufacturer instructions for effective detection.
In general the strips must be air dried until the solvent evaporates and then exposed to
moisture for proper operation.

incident. That person should remain at the reported location until contacted by emergency
personnel.
*Close doors to affected areas
*If splash to the skin or eyes has occurred flush affected areas with copious quantities of
water for 15 minutes. Call the UCSD Poison Information Center 543-6000 for specific
information. If the exposed individual is transported to a medical facility advise the Poison
Control Center of where the patient is going to allow continued assistance and to allow
Poison Control to alert the treating physicians of the nature of the exposure and the
appropriate medical response.
LABORATORY SPECIFIC PROCEDURES:
Notify individuals in the area of the spill.
If it can be done safely, attend to injured or contaminated persons and remove them from
exposure.
Avoid breathing vapors of spilled material.
Evacuate nonessential personnel.
If spilled material is flammable, turn off ignition and heat sources.
Wear protective equipment.
Confine spill to a small area, absorb and/or neutralize as appropriate. Collect residues,
place in container, and dispose of as chemical waste. NOTE: Do not neutralize spilled
liquid unless you are sure that the resulting reaction will not release hazardous gases,
products or cause explosion.
Clean spill area with water or a buffer solution.
Supplies and Equipment:
1) Non-reactive absorbents such as oil-dry, vermiculite, or commercially available
absorbent pads should be available in the laboratory for liquid spills. NOTE: Paper
towels, may be used for incidental spills and for final wipe up, but caution should be
exercised because some chemicals, such as oxidizers, may cause ignition on contact or
in a delayed fashion through reaction.
2) Neutralizing agents including sodium carbonate or bicarbonate (for acid spills), and
citric acid (for basic spills) or commercial spill products will be stored _____________
and reserved for spill use.
3). A plastic dust pan, whisk broom with heavy plastic bags will be stored

SITE SPECIFIC ENGINEERING CONTROLS AND VENTILATION
INFORMATION
List protective engineering controls and systems available in the laboratory. Include
information on restrictions, special precautions or procedures, preventative maintenance
schedules and any other information relevant to safe operation in the laboratory.
Ventilation System: The ventilation system is a "one-pass" system. Air is supplied by
diffusers in the laboratory with exhaust provided by fume hoods. The laboratory is
maintained a negative pressure relative to the public areas such as hallways to prevent
spread of contaminants or accidental releases. There is no recirculation of exhausted air.
Fume Hoods: Fume hoods are to be used for containment of all work with volatile
hazardous compounds, hazardous dusts, gases and other materials that may constitute
an airborne exposure hazard unless other effective control measures are available.
Work shall be conducted at least 6 inches back from the front face of the hood. Storage in
the hood shall be kept to a minimum practical level. The back baffles of the hood should
not be obstructed by excessive stored materials.
If the fume hood has not been tested within the last year or if there is a concern for
improper hood operation contact EH&S for a hood evaluation.
Fume hoods assigned to a primary user should be labeled with the name of the user and
a home and office phone number. If there are long term procedures performed, such as
overnight distillation, a short description of the procedure and materials should be posted
on the hood sash.
Environmental Rooms: Typically there is no ventilation to provide fresh air to
environmental rooms. Any use of toxic materials or flammable liquids in a warm or cold
room can result in a buildup of hazardous concentrations of airborne contaminants.
Flammable and toxic liquids or gases should not be used in environmental rooms.
Gas Cabinets: Gas cabinets shall be used for the use and storage of highly toxic gases.
Supply lines from the cabinets to the point of use shall be a continuous metal tube without
joints or connections. Tygon or other plastic tubing shall not be used for transport of highly
toxic or corrosive gas across laboratory space.
Glove Boxes:
Autoclaves:
See autoclave SOP

Room(s)__________________________
PERSONAL PROTECTIVE EQUIPMENT AVAILABLE
IN THE LABORATORY
List the personal protective equipment available to laboratory personnel.
See Chapter V for additional information.
Laboratory Attire: Laboratory workers should wear clothing appropriate to their
environment and laboratory operations. Typically closed toed shoes and clothing which
provides coverage for the extremities.
Eye Protection: Eye protection is required in all laboratory areas. The level and
selection of eye protection is based on the potential hazard presented from operations
conducted and the nature of the laboratory work in general. Safety glasses with side
shields which meet ANSI Z87.1 (all glasses which meet this standard have Z87.1
imprinted on the temple bar) is the minimum protection for all chemistry and biochemistry
laboratories.
Goggles will be used if a splash hazard exists with toxic or irritating chemicals. This
includes operation such as but not limited to: pouring liquids, such as organic solvents, at
or above eye level, pouring large quantities of liquids, using liquids under pressure.
A full faceshield with goggles will be used in instances such as when working with large
quantities of liquids or gases that are toxic or corrosive, such as with phenol or
hydrochloric acid. A face shield with neck protection will be used if an explosion or
implosion hazard exists.
Glasses, a faceshield, or shielding designated by the manufacturer as providing
ultraviolet (UV) protection should be used when potential UV exposure exists (eg. using a
gelbox or using a UV lamp for chemical ionization).
Gloves: Many laboratory operations require skin and hand protection. Gloves will be
selected based on the chemical and physical hazards presented by an operation.
Disposable/single use latex gloves offer little or no protection from most solvents and can
develop small holes that are often not readily apparent to the wearer. Single use latex
and should only be used if minimal consequences could result from skin contact.
Single use nitrile disposable gloves should be used for general laboratory operations.
The gloves should be changed frequently and whenever contamination has occurred.
Heavy gloves should be worn over the nitrile gloves when using large quantities of
chemicals or when contamination will be known to occur. The outer glove should be
selected based on chemical
compatibility. Long gauntlet style gloves will be used when a potential exists for splash to
the arm of significant quantities of corrosive or toxic materials.
Personal Protective Equipment- continued
Other: A laboratory coat will be worn when working at the bench.
A neoprene or PVC apron shall be worn when working with large quantities of acids, with
corrosives under pressure, and with liquid phenol.
Building_____________________________
Room(s)________________________________
PRIOR APPROVALS REQUIRED
List prior approvals required for particular laboratory functions. The
Principal Investigator or Laboratory Supervisor will determine which
laboratory operations, if any will require prior approval.
Unattended or overnight operations.
Use of highly toxic gas (eg. nitric oxide, phosgene, hydrogen fluoride, arsine, phosphine)
in any amount. Use of large quantities of toxic or corrosive gases.
Use of regulated carcinogens
Others:
WORKING ALONE AND UNATTENDED OPERATIONS
Experiments known to be hazardous should not be conducted while alone in
the laboratory. Individuals performing low hazard tasks in off hours should make
arrangements with other individuals working in the building to cross check each other
periodically.
Laboratory operations that require continuous or overnight operation must have PI prior
approval. The process or experiment should be designed with provision to prevent
release of hazardous materials in the event of interruption of utilities such as electricity,
cooling water, or inert gas. Laboratory lights should be left on and a descriptive sign
posted identifying the nature of the experiment, the hazardous substances in use and
emergency contact information.

STANDARD OPERATING PROCEDURES
READ AND REVIEW MSDS'S BEFORE USING ANY MATERIAL FOR THE FIRST TIME
1) Safety considerations will be included in initial experimental design. SOP's will be
developed and documented for hazardous chemicals when the chemical is used routinely
in the laboratory and when its use poses a potential hazard to laboratory personnel. All
highly toxic and toxic gases, unstable compounds that may explode, pyrophoric materials,
and highly toxic liquids and solids require development of an SOP even for a single event
due to hazards to personnel. Elements to be addressed when designing experiments or
procedures are: material hazards, availability of alternative safer materials, engineering
controls, personal protective equipment required, spill or release potential and possible
consequences, and other special considerations such as extreme reactivity.
SOP's may be developed by: process, such as distillation, peptide synthesis; each
hazardous chemical, such as cyanogen bromide; class of hazardous chemicals, such as
organic solvents or peroxidizable chemicals, or by any other reasonable approach that
addresses the health and safety concerns of the experiment.
SOP elements may be addressed in the laboratory notebook as part of the experiment or
process description or using the format provided on the SOP form. Elements 1 through 7
should be addressed for each process, class of chemicals, or individual chemical. For
"particularly hazardous substances" three additional elements, 8 through 10, must be
completed.
Element 1 Process or Experiment: State the process or type of process that involves the
use of hazardous chemicals.
Element 2 Hazardous chemicals/Class of Hazardous Chemicals: State hazardous
chemicals used or hazardous byproducts or reaction products produced.
Element 3 Personal Protective Equipment: State the personal protective equipment
selected and required and hygiene practices.
Element 4 Engineering/Ventilation Controls: Describe any specific engineering controls
whose use is required to prevent employee exposures to hazards, such as fume hoods,
interlocks on equipment, explosion shielding, ultraviolet light shielding,, and safety
features on equipment.
Element 5 Special Handling Procedures and Storage Requirements: Describe special
storage requirements (eg. special containment devices, etc. Describe safe methods of
transporting chemicals, such as double containment.
Element 6 Spill and Accident Procedures: Describe any special procedures for spills or
releases (eg. neutralizing agents, use fluorescence to detect materials). Indicate how
spills or accidental releases should be handled and by whom.
Element 7 Waste Disposal: Describe any special waste disposal procedures for these
chemicals/processes.
Element 8 Approval Required: Indicate if and when an approval from the PI or supervisor
is required.
Element 9 Decontamination: Discuss any specific decontamination procedures for
equipment and glassware or areas.
Element 10 Designated Area: Indicate the designated area for work with this chemical or
process. A designated area must be established for work with "particularly hazardous
substances" (See chapter XIV of the laboratory Safety Guide). The entire laboratory, fume
hood or a portion of the laboratory may be considered as a designated area.
APPENDIX I
GENERAL CHEMICAL COMPATIBILITY STORAGE GROUPS
1) Mineral (inorganic) Acids Examples: hydrochloric acid, sulfuric acid, phosphoric
acid, boric acid, hydrobromic acid.
2) Oxidizers Examples: bromic acid, perchloric acid, chromic acid, nitric
acid, many perchlorates, permanganates, bromine, chlorine, fluorine, silver nitrate.
Note: Oxidizers should not be stored directly on wooden shelves or on paper shelf liners.
Spills may react with the organic portion of the shelf or paper and ignite spontaneously.
Perchloric acid presents special hazards and should be given special consideration to
assure effective isolation from oxidizable materials and dehydrating agents. Hypochlorite
solutions (i.e. bleach) are oxidizers however they will release chlorine gas on contact with
acids thus should be stored separately.
3) Bases/Caustics Examples: aqueous ammonia, ammonium hydroxide,
potassium hydroxide, sodium hydroxide.
4) Organic Solvents/Acids Examples: acetone, methanol, isopropyl ether,
methylene chloride, carbon tetrachloride, acetic acid, citric acid, benzene, tetrahydrofuran.

pentachlorophenol, hydrazine, botulinum toxin, acrylamide, methyl isocyanate, phorbol
esters.
6) Pyrophoric Materials Examples: boron, diborane, dichloroborane, 2-
furaldehyde, diethyl aluminum chloride, lithium, white or yellow phosphorus, trimethyl
aluminum.
7) General "Dry" Examples: this would include many of the relatively
Lab Chemicals innocuous or unreactive materials commonly found
in laboratories.
8) Gases Segregate also according to hazard class. Acutely toxic
and toxic gases should be stored in gas cabinets or fume hoods.
9) Water Reactives Examples: aluminum chloride-anhydrous, calcium
carbide, acetyl chloride, chlorosulfonic acid, phosphorous pentachloride, sodium,
potassium, calcium, aluminum tribromide, calcium oxide, acid anhydrides, metal hydrides.
10) Controlled Substances Narcotics and other controlled substances should
be stored in a secure locked location such as a drawer or safe. See PPM Section 523-
2.2.1
