INTERNAL EXPOSURE: The manufacturers of this material have established an internal exposure limit value of 0.07 ppm as an 8-hour time
weighted average. The basis for the exposure limit is irritation of the eyes, skin and mucous membranes. A skin notation is warranted due to
the evidence that MITC-FUME can penetrate the skin and cause systemic toxicity.

Osmose MATERIAL SAFETY DATA SHEET
SPECIAL FIRE FIGHTING PROCEDURES: Evacuate enclosed and surrounding areas. If smoke and fumes cannot be avoided, use
proximity suit and self-contained breathing apparatus. Use water spray to cool containers and disperse vapors. Keep spills away from
sources of ignition.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Burning material releases toxic nitrous oxide and sulfur dioxide gases. Product vapor forms
explosive mixtures with air; prevent build-up of electrostatic charges, sparks, and open flame.
SECTION V - REACTIVITY DATA
IS THIS CHEMICAL STABLE UNDER NORMAL CONDITIONS OF HANDLING/STORAGE (Y/N)? Y
CONDITIONS TO AVOID (REGARDING STABILITY): Heat and/or direct sunlight. Presence of water, especially above 140掳F.
INCOMPATIBILITY (MATERIALS TO AVOID): Avoid contact with oxidizing materials, water above 140掳F, iron, PVC, and rubber (hoses).
HAZARDOUS DECOMPOSITION PRODUCTS: Carbon oxysulfide, hydrogen sulfide and methylamine may be formed upon contact with
hydrolyzing agents (e.g. water). Violent reactions and formation of sulfur dioxide occur upon reaction with oxidants.
HAZARDOUS POLYMERIZATION POSSIBLE (Y/N)? N
CONDITIONS TO AVOID (REGARDING POLYMERIZATION): N/A
SECTION VI - HEALTH HAZARDS
ROUTES OF ENTRY: Skin, Oral, Inhalation, Eye
SIGNS AND SYMPTOMS OF ACUTE OVEREXPOSURE: Fatal if inhaled or absorbed through skin. May be fatal if swallowed. Corrosive
(rabbit - eye). Causes irreversible eye damage and skin burns. All kinds of exposure cause severe irritations of skin and mucous membranes
with burning pains and risk of sensitization and of corneal opacities. Short term contact mostly subsides without lasting consequences.
Addition of organic solvents enhances penetration through skin.
CHRONIC OVEREXPOSURE: No chronic effects are known for humans.
CHEMICAL LISTED AS A CARCINOGEN OR POTENTIAL CARCINOGEN?:
鈥? NATIONAL TOXICOLOGY PROGRAM (Y/N): N
鈥? IARC MONOGRAPHS (Y/N): N
鈥? OSHA (Y/N): N
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Conjunctivitis of the eye, dermatitis of the skin, asthma and
respiratory diseases.
TOXICITY DATA: Oral LD50: 67 mg/kg, (Rat) Inhalation LC50: 1900 mg/M3, (1 hour).
EMERGENCY AND FIRST AID PROCEDURES
EMERGENCY PHONE NUMBER OF MANUFACTURER: 1-(800) 424-9300
1. INHALATION: Move victim to fresh air. If heavy exposure, apply artificial respiration and/or oxygen and call a physician
immediately. Inhalation of anti-inflammatory sprays, local anesthetics, if appropriate.
2. EYE CONTACT: Flush with plenty of water and, at intervals, rinse with 5% aqueous sodium bicarbonate solution. Call an
Ophthalmologist immediately for further treatment (hydrocortisone eye-drops at 1/2 hour intervals).
3. SKIN CONTACT: Remove contaminated clothing and absorb remaining product from skin by means of cotton pads, paper towels, or
similar. Clean contaminated skin areas carefully with plenty of water or 5% sodium bicarbonate solution. Give
medical treatment as for acute dermatitis.
4. INGESTION: Drink promptly a large quantity of milk, egg whites, gelatin solution or a large quantity of water or aqueous sodium
sulfate solution. Do not administer alcohol or castor oil. Do not induce vomiting. Remove contents in stomach by
gastric lavage and catharsis. Rinse stomach, if possible (physician - possible mucosal damage may
contra-indicate use of gastric lavage!), check function of organs and treat as appropriate for symptoms of
poisoning.
SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE
SHIPPING DESCRIPTION: Preservatives, Wood, NOI, Liquid in inner containers in boxes.
NMF 161490 Methyl isothiocyanate, 6.1, UN2477, PGI
This Package Conforms to Conditions and Limitations Specified in
49 CFR 173.4 and DOT-E 11900.
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Store only in closed original container to prevent leakage. Store in cool,
well ventilated, locked areas away from food and foodstuff, out of reach of children and irresponsible persons. Avoid exposure to heat and/or
direct sunlight.
OTHER PRECAUTIONS: Do not drop container or slide across sharp objects.
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Cover with cold water. Product will solidify. Recycle, if possible
or add solid scale in small amounts to drum with 10% aqueous ammonia solution. Product will react with ammonia to form N-Methyl thiourea.

WASTE DISPOSAL METHODS: Wood treated with MITC-FUME IS NOT a hazardous waste. If unused MITC-FUME is disposed of it may be
considered a hazardous waste (as per RCRA) because of its ignitability. Disposal of such material should be conducted by an EPA
permitted facility. Questions regarding disposal can be directed to EPA's RCRA Hotline at (800) 424-9346. Always dispose in accordance
with all Federal, State and Local Laws.
SECTION VIII - CONTROL MEASURES
RESPIRATORY PROTECTION: Under normal use, there is no need for respiratory protection. If MITC-FUME is to be used in an enclosed
area, a positive pressure supplied air respirator equipped with full face piece should be used during any operation where there Is potential for
release of this product to workplace air.
VENTILATION REQUIREMENTS: Yes
OTHER: Refer to "Industrial Ventilation" by ACGIH for a manual of recommended practices.
PROTECTIVE GLOVES: Rubber or neoprene (limited protection, replace frequently)
EYE PROTECTION: Goggles, safety glasses, or face shield.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT: Acid-resistant non-porous overalls or aprons.
WORK/HYGIENIC PRACTICES: Remove contaminated clothing immediately and launder before reuse. Heavily contaminated clothing
should be disposed of. Wash thoroughly after handling, before eating or smoking.
