============= Composition/Information on Ingredients =============
Name:METHYL IODIDE
CAS:74-88-4
Fraction by Wt: 100.0%
===================== Hazards Identification =====================
Reports of Carcinogenicity:NTP:No IARC:No OSHA:No
Health Hazards Acute and Chronic:INHALATION: SHORT TERM EXPOSURE:
irritation, nausea, vomiting, diarrhea, headache, drowsiness,
symptoms of drunkenness, blurred vision, lung congestion,
convulsions, coma, death LONG TERM EXPOSURE: visual disturbances
SKIN CONTACT: SHORT TERM EXPOSURE: irritation, blisters, rash,
symptoms of drunkenness LONG TERM EXPOSURE: burns EYE CONTACT:
SHORT TERM EXPOSURE: irritation (possibly severe) LONG TERM
EXPOSURE: same as effects reported in short term exposure
INGESTION: SHORT TERM EXPOSURE: vomiting, digestive disorders,
symptoms of drunkenness LONG TERM EXPOSURE: no information is
available
Medical Cond Aggravated by Exposure:
======================= First Aid Measures =======================
First Aid: INHALATION: If adverse effects occur, remove to
uncontaminated area. Give artificial respiration if not breathing.
If breathing is difficult, oxygen should be administered by
qualified personnel. 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 swallowed, drink plenty of water, do NOT induce vomiting. Get
immediate medical attention. Induce vomiting only at the
instructions of a physician. Do not give anything by mouth to
unconscious or convulsive person. NOTE TO PHYSICIAN: For
inhalation, consider oxygen. For ingestion, consider gastric
lavage, activated charcoal slurry and catharsis.
===================== Fire Fighting Measures =====================
Flash Point:No data available.
Extinguishing Media:regular dry chemical, regular foam, water Large
fires: Use regular foam or flood with fine water spray.
Fire Fighting Procedures:Move container from fire area if it can be
done without risk. Fight large fires from a protected location or
safe distance. Stay away from the ends of tanks. Dike for later
disposal. Do not scatter spilled material with high-pressure water
streams. Do not attempt to extinguish fire unless flow of material
can be stopped first. Use extinguishing agents appropriate for
surrounding fire. Flood with fine water spray. Cool containers with
water spray until well after the fire is out. Apply water from a
protected location or from a safe distance. Avoid inhalation of
material or combustion by-products. Stay upwind and keep out of low
areas. Consider downwind evacuation if material is leaking.
Unusual Fire/Explosion Hazard:Negligible fire hazard.
================== Accidental Release Measures ==================
Neutralizing Agent:
====================== Handling and Storage ======================
Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Keep separated from
incompatible substances. Store in a tightly closed container. Avoid
contact with water or moisture.
Other Precautions:
============= Exposure Controls/Personal Protection =============
Respiratory Protection:The following respirators and maximum use
concentrations are drawn from NIOSH and/or OSHA. At any detectable
concentration - 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 air-purifying respirator with a full facepiece
and an organic vapor canister. Any appropriate escape-type,
self-contained breathing apparatus. 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.
Ventilation:Provide local exhaust or process enclosure ventilation
system. Ensure compliance with applicable exposure limits.
Protective Gloves:Wear appropriate chemical resistant gloves.
Eye Protection:Wear splash resistant safety goggles with a faceshield.
Provide an emergency eye wash fountain and quick drench shower in
the immediate work area.
Other Protective Equipment:Wear appropriate chemical resistant
clothing.
