HEALTH & SAFETY INFORMATION
• IDLH:
1600
ppm/4928 mg/m3
• Odor threshold:
recognition 2.03 – confirmation 123 mg/m3
•
OSHA Table Z-1 Air Contaminant
•
Vapor is a respiratory tract irritant; high concentrations causes smarting of
the eyes and respiratory system and may cause drowsiness, dizziness, headache.
The effect is temporary. Liquid causes severe eye irritation, defatting of the
skin, skin cracking.
Exposure Limits:
•
ACGIH TLV: 50 ppm TWA
•
OSHA PEL: 100 ppm/300 mg/m3 TWA
•
NIOSH REL: 50 ppm/150 mg/m3 TWA

GMFOV [any air-purifying, full-facepiece respirator (gas mask) with a
chin-style, front- or back-mounted acid gas canister] PAPRTOV [any powered,
air-purifying respirator with a tight-fitting facepiece and organic vapor
cartridge(s)] SCBAF (any self-contained breathing apparatus with a full
facepiece) SAF (any supplied-air respirator with a full facepiece).
Emergency or Planned Entry into
Unknown Concentrations or IDLH Conditions
SCBAF:PD,PP (any self-contained breathing apparatus that has a
full facepiece and is operated in a pressure-demand or other positive-pressure
mode) SAF:PD,PP:ASCBA (any supplied-air respirator that has a full facepiece
and is operated in a pressure-demand or other positivepressure mode in
combination with an auxiliary selfcontained breathing apparatus operated in a
pressuredemand or other positive- pressure mode).
Escape:
GMFOV
[any air-purifying, full-facepiece respirator (gas mask) with a chin-style, front-
or back-mounted organic vapor canister] SCBAE (any appropriate escape-type,
self-contained breathing apparatus).
Note:
Substance reported to cause
eye irritation or damage; may require eye protection.
Reactivity:
Forms
explosive mixture with air. Incompatible with strong acids, mineral acids,
strong oxidizers, caustics, aliphatic amines, isocyanates, alkali metals, and
alkaline earth. Attacks some plastics, rubber, and coatings. May react with
aluminum at high temperatures.
FIRE INFORMATION:
Vapor may travel ling distances to sources of ignition and flash
back. Vapor in confined areas or containers may explode in fire. If material or
contaminated runoff enters waterways, notify downstream users of potentially
contaminated water.

FIRST AID:
Move
victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Administer oxygen if breathing is difficult. Remove
and isolate contaminated clothing and shoes. In case of contact with substance,
immediately flush skin or eyes with running water for at least 20 minutes. Wash
skin with soap and water. Keep victim warm and quiet. Effects of exposure
(inhalation, ingestion or skin contact) to substance may be delayed. Ensure
that medical personnel are aware of the material(s) involved, and take
precautions to protect themselves.
