ACTIVATED CARBON (CAS 7440-44-0)            100      No

EMERGENCY OVERVIEW:
Odorless black powder.  Activated carbon (especially when wet) can
deplete oxygen from air in enclosed spaces, and dangerously low levels of
oxygen may result.  When workers enter a vessel containing activated carbon,
procedures for potentially low oxygen areas should be followed.  Workers
should also take appropriate precautions when dealing with spent (used
activated carbons which may exhibit properties of adsorbed materials.
                                                                               
POTENTIAL HEALTH EFFECTS:
Medical conditions aggravated by exposure: none documented
                                                                               
ROUTES OF EXPOSURE:
EYES:
 Not corrosive, but like most particulate materials, may cause mild
physical irritation.
                                                                               
Skin:
Not corrosive, and not a primary skin irritant.
Mild irritation is possible due to abrasive action of dust.
                                                                               
INGESTION:  No known deleterious effects.
                                                                               
INHALATION: Possible mild irritation of respiratory tract due to drying and
abrasive actions of dust.
                                                                               
CHRONIC EFFECTS: IARC: not listed  NTP: Not listed   OSHA: Not regulated
                                                                               
For additional information, see section 16.

FIRST AID PROCEDURES:
                                                                               
SKIN:  Wash material off the skin with soap and water.  If irritation occurs,
get medical attention.
                                                                               
EYES: Flush with copious amounts of water. Seek medical attention if
irritation occurs.
                                                                               
INGESTION:  Give one or two glasses of water to drink. Seek medical attention
if gastrointestinal symptoms develop.
                                                                               
INHALATION:  Remove victim to fresh air. Seek medical attention
if cough or other respirator symptoms develop.
 

FLASH POINT:  Not Applicable
                                                                               
NON-FLAMMABLE:  OSHA Method 16CFR1500.44 (Incorporated by reference in
29CFR1910.1200).
                                                                               
NOT SPONTANEOUSLY COMBUSTIBLE:  DOT Method 49CFR Part 173, Appendix E.
                                                                               
FLAMMABILITY LIMITS IN AIR:  LFL, and UFL not applicable.
                                                                               
GENERAL HAZARD:  Activated carbon is difficult to ignite and tends to burn
slowly (smolder) without producing smoke or flame.  Toxic gases will form upon
combustion.
                                                                               
FIRE FIGHTING INSTRUCTIONS: If possible to do safely, move smoldering
activated carbon to a non-hazardous area, preferably out of doors.  Extinguish
fire using water fog, fine water spray, carbon dioxide or foam. Avoid
stirring up dust clouds.
                                                                               
FIRE FIGHTING EQUIPMENT: Respiratory and eye protection
required for fire fighting personnel includes full protective equipment
(Bunker Gear).  A self-contained breathing apparatus (SCBA) should be used
for all indoor fires and any large outdoor fires.
..
HAZARDOUS COMBUSTION PRODUCTS:  Products may include smoke and oxides of
carbon (for example, carbon monoxide).  Materials allowed to smolder for long
periods in enclosed spaces, may produce amounts of carbon monoxide which reach
the lower explosive limit (carbon monoxide LEL = 12.5% in air).  Under certain
conditions, any airborne dust may be an explosion hazard.
 

IF A SPILL OR LEAK OCCURS:
Clean up spills in a manner that does not disperse dust into the air.
Handle in accordance with good industrial hygiene and safety practices.
These practices include avoiding unnecessary exposure, and removal
of material from eyes, skin and clothing.
                                                                               
DISPOSAL METHOD:  Dispose of virgin (unused) carbon (waste or spillage) in a
facility for non-hazardous wastes.  Spent (used) carbon should be disposed of
in accordance with applicable laws.
                                                                               
CONTAINER DISPOSAL:  Do not reuse empty bags.  Dispose of in facility
permitted for non-hazardous waste.

STORAGE TEMPERATURE:  Ambient
                                                                               
STORAGE PRESSURE:  Atmospheric
                                                                               
HANDLING: follow good handling and housekeeping practices to minimize spills,
generation of airborne dusts, and accumulation of dusts on exposed surfaces.
Use with adequate exhaust ventilation to draw dust away from workers'
breathing zones.
Prevent or minimize exposures to dusts by using appropriate respirators,
gloves, and eye protection.
Wash exposed skin areas thoroughly  with soap and water after handling.
                                                                               
STORAGE: Product should be stored in a closed dry container.  Maintain good
housekeeping procedures. Store away from strong oxidizers such as ozone,
liquid oxygen, chlorine, permanganate, etc.
 

ENGINEERING CONTROLS:
Use local exhaust ventilation to control emissions near the source.
Ventilation systems should be sized and configured to prevent exceedence of
recommended or regulated exposure limits (for example, OSHA PELS).
                                                                               
EYE PROTECTION:  Safety glasses with side shields recommended for any type of
handling. Where eye contact or dusty conditions may be likely, dust tight
goggles are recommended. Have eye flushing equipment available.
                                                                               
SKIN PROTECTION:  Avoid contact with the skin.  Wear appropriate dust
resistant clothing. Wash contaminated clothing and clean protective equipment
before reuse.  Wash skin thoroughly after handling.
                                                                               
RESPIRATORY PROTECTION:  Use NIOSH/MSHA approved respiratory protection
equipment appropriate to the material and/or its concentration where airborne
exposure is likely.  If exposures cannot be kept to a minimum with engineering
controls, consult respirator manufacturer to determine appropriate type
equipment for a given application.  Observe respirator use imitations
specified by NIOSH/MSHA or the manufacturer.

* OSHA and ACGIH have not established specific exposure limits for this
material. However, OSHA and ACGIH have established limits for nuisance dusts
which are the least stringent exposure limits applicable to dusts. The OSHA
PEL/TWA for particulates not otherwise classified (nuisance dusts) is 15 mg/m3
total dust (TD) and 5 mg/m3 respirable dust (RD)). The ACGIH TLV/TWA for
particulates not otherwise classified is 10 mg/m3 total dust (TD). These
limits are stated only to indicate the least stringent airborne dust exposure
levels applicable to nuisance dusts. Use control measures as specified above
to minimize exposure.
