SPILL PROCEDURES

• In the event of a MAJOR SPILL (?500ml)
• 1) Notify persons in the immediate area that a
  spill has occurred.
• 2) Avoid breathing vapors, mists or dust of the
  spilled material.
• 3) Turn off all ignition sources, if possible.
• 4) If injured or contaminated with a hazardous
  substance immediately implement personal
  decontamination procedures (i.e. eyewash, safety
  shower, etc.) prior to reporting spill.
• 5) Evacuate room and close the door
• 6) Contact 215-895-2222
• 7) In order to asses the situation be prepared to
  provide the following information
• Name and call back number
• The location of the spill (building and room
  number)
• Type of material spilled
• The amount of material spilled
• 8) Remain on or near the telephone until you have
  received instructions from the emergency operator.

PERSONAL DECONTAMINATION PROCEDURES
1) For spills contacting the SKIN Immediately
flush with flowing water for no less than 15
minutes (i.e. sink or safety shower). Check the
MSDS to see if any delayed effects should be
expected.
2) For spills on CLOTHING Do not attempt to
wipe the clothes. Quickly remove all
contaminated clothing, shoes, and jewelry while
using the safety shower. Take care not to spread
the chemical on the skin or, especially, in the
eyes. Use caution when removing pullover shirts
or sweaters to prevent contamination of the eyes
it may be better to cut the garments off.
Immediately flood the affected body area with
warm water for no less than 15 minutes.
3) For splashes into the EYE Using the eyewash
immediately flush for at least 15 minutes. Hold
the eyelids away from the eyeball, and move the
eye up and down and sideways to wash thoroughly
behind the eyelids

Safe Operating Procedures for Chemical Fume Hoods
Know the toxic properties of the chemicals with
which you work. Be able to identify signs and
symptoms of overexposure. Prior to performing
work in a chemical fume hood be sure the fume
hood is exhausting properly. Laboratory
personnel shall not lean into the hood so that
his/her head is inside the plane of the hood face
without adequate respiratory and personal
protection, except for setup or hood
maintenance. Place chemical sources and apparatus
at least 6 inches behind the face of the hood.
Place equipment as far to the back of the hood
as practical without blocking the bottom baffle.
Keep sash completely lowered anytime no
"hands-on" part of an experiment is in progress.
Close sash when finished with hood work or when
leaving experiments or chemicals unattended. The
hood sash shall not be removed or left completely
open except for setup work.
5
Safe Operating Procedures for Chemical Fume Hoods
Keep sash clean and clear. The hood sash shall
be closed to the lowest position possible while
still allowing comfortable working
conditions. Fume hoods shall not be used for
storage space with the exception of chemical
waste containers. All chemicals not being used
for an experiment shall be removed from the hood
and placed in their proper storage area until
needed. Laboratory personnel shall clean up all
minor spills in the hood immediately. Clean all
chemical residues from the hood chamber when
finished with work. All electrical devices
should be connected outside the hood to avoid
sparks, which may ignite a flammable or explosive
chemical. The hood sash is not a substitute for
personal protective equipment. Laboratory
personnel shall wear safety glasses, laboratory
coat, and gloves at all times when working with
chemicals in the hood.

EXTINGUISHERS
Types of fire Class A Fires involving ordinary
combustible materials such as wood, cloth, paper,
rubber, or plastic. Class B Fires involving
combustible liquids such as gasoline or kerosene,
flammable gasses, and grease. Class C Fires
involving energized electrical equipment. Class
D Fires involving certain combustible metals
such as magnesium, titanium, zirconium, sodium
and potassium.
1) Water class A only. Time of discharge - 1
min. 2) Multipurpose Dry Chemical Classes A, B,
C - 10 -25 sec. 3) Carbon Dioxide Classes B, C -
10 -30 sec. (In our lab) 4) Dry Chemical (Sodium
Bicarbonate) Classes B and C - 10 to 25 sec. 5)
Dry Powder for Metal Fires Class D
7
IF YOU DISCOVER A FIRE
R.A.C.E. Rescue - Remove everyone from the area
Alarm - Sound the nearest fire alarm Confine -
Close doors to isolate area Evacuate -
To remember how to operate a portable
extinguisher, think of the word P.A.S.S. Pull
the pin by grasping the extinguisher neck in one
hand and removing the pin with the other. Aim
the nozzle, hose, or horn at the base of the
fire. Squeeze the handle to release the
extinguishing agent. Sweep from side to side at
the base of the fire until it appears to be out.

PRACTICAL LIFE IN THE LAB

• Benches should be cleaned on a daily basis
• Practically everyone should leave a clean
  working area
• Everyone should be present for the weekly
  cleaning
• Vials should be recycled (cleaned only, washed
  with soap and DI water)
• If common lab supplies are needed, fill the form
  
• Samples labeling the solvent name MUST be
  written entirely
• Example Dimethylformamide not DMF.
• If possible, use the diamond sign

9
PRACTICAL LIFE IN THE LAB

• When using the sample processing area (short
  time storage, 2 days max), label with chemical
  name, owner and expected time to be removed.
• When a new chemical is received, update the
  chemical list on the intranet, print the new list
  and replace the old one on the cabinet.
• A safety lecture should be given every quarter
  regarding specific risks
• - compressed gas operation
• - PPE, chemicals handling
• Wastes disposal everyone is responsible for his
  own wastes
• - A form will be available in the lab, on the
  safety items bench.
• - Online chemical pick-up request

WASTES DISPOSAL
Drain disposal permited for Neutralized acidic
and caustic aqueous solutions (ph adjustment of
waste that are hazardous only because they
exhibit the corrosivity characteristic). Final pH
value 6-9. All drain discharges will be
documented on a log sheet located near the point
of discharge. (date, chemical name, volume and
pH). The University Department of Safety Health
will collect the log sheet bimonthly. Common
salts, sugars and agars in both liquid and solid
forms. For solids, the material must be
dissolved in tap water. Limit 1kg of solid or
1l of liquid.
Drain disposal NOT permited for Flammable or
explosive pollutants Pollutants that will
cause corrosive structural damage Solid or
viscous pollutants that may cause an
obstruction Pollutants capable of releasing
fumes or vapors Petroleum, oil,
non-biodegradable cutting oil Organic
chemicals Heavy metal solutions
11
WASTES DISPOSAL
Storage is allowed from the generation of the
waste up to 90 days
Residual materials (less than 1 milliliter) may
be rinsed from containers and disposed of down
the drain.
Laboratories may accumulate as much as 5 gallons
of hazardous waste or one quart of acutely
hazardous waste (immediately hazardous to life
and health)
All containers must be labeled with the complete
chemical name of each primary component.
Formulas, acronyms and abbreviations are not
acceptable. If possible, the label should
include the approximate percentage of each
chemical. Do not place the date or the words
Hazardous Waste on the container.

PRACTICAL LIFE IN THE LAB

• You should always know
• The location of the phone, fire extinguisher,
  eyewash
• Safety Dept. number 2222
• 3) The R.A.C.E. and P.A.S.S.
