Medical Cond Aggravated by Exposure:

First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
Get immediate medical attention. SKIN CONTACT: Wash skin with soap
and water for at least 15 minutes while removing contaminated
clothing and shoes. Get medical attention, if needed. Thoroughly
clean and dry contaminated clothing and shoes before reuse. EYE
CONTACT: Flush eyes with plenty of water for at least 15 minutes.
Then get immediate medical attention. INGESTION: If a large amount
is swallowed, get medical attention. NOTE TO PHYSICIAN: For
inhalation, consider oxygen. For ingestion, consider gastric
lavage. Consider oxygen.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Protect from physical
damage. Store in a cool, dry place. Store in a well-ventilated
area. Avoid heat, flames, sparks and other sources of ignition.

atmosphere. Keep separated from incompatible substances.
Other Precautions:

Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. 625 ppm Any
supplied-air respirator operated in a continuous-flow mode. 1250
ppm Any supplied-air respirator with a full facepiece that is
operated in a pressure-demand or other positive-pressure mode. Any
self-contained breathing apparatus that has a full facepiece and is
operated in a pressure-demand or other positive-pressure mode. 5000
ppm Any supplied-air respirator operated in a continuous-flow mode.
Any supplied-air respirator with a full facepiece that is operated
in a pressure-demand or other positive-pressure mode. Any
self-contained breathing apparatus that has a full facepiece and is
operated in a pressure-demand or other positive-pressure mode. For
Unknown Concentrations or Immediately Dangerous to Life or Health -
Any self-contained breathing apparatus that has a full facepiece
and is operated in a pressure-demand or other positive-pressure
mode. Any supplied-air respirator with full facepiece and operated
in a pressure-demand or other positive-pressure mode in combination
with a separate escape supply. Escape - Any appropriate
escape-type, self-contained breathing apparatus with full facepiece
operated in pressure-demand or other positive pressure mode. Any
air-purifying respirator with a full facepiece and an organic vapor
canister. For Unknown Concentrations or Immediately Dangerous to
Life or Health - Any supplied-air respirator with full facepiece
and operated in a pressure-demand or other positive-pressure mode
in combination with a separate escape supply. Any self-contained
breathing apparatus with a full facepiece.
