                           3 HAZARDOUS IDENTIFICATION



EYE: Direct contact with liquid may cause irritation experienced as

stinging, discomfort or pain.



SKIN: Direct contact may cause irritation, which may be experienced as

itching or slight local redness. Prolonged and/or repeated contact with

the skin may cause irritation characterized by redness, cracking and

blistering. May be absorbed in toxic amounts through the skin when direct

contact is extensive and over a prolonged period of time.



INHALATION: Inhalation of high concentrations of vapors may cause

respiratory tract irritation, producing symptoms of nausea in poorly

ventilated areas.



             May cause gastrointestinal disturbances such as nausea,

INGESTION:

vomiting, diarrhea and effects similar to those described under INHALATION.



Individuals with pre-existing disease in or a history of ailments involving

the skin, eye, respiratory tract, liver, kidney, central nervous system are

at a greater than normal risk of developing adverse effects when exposed to

this material.



                              4 FIRST AID MEASURES



EYE CONTACT: Hold eye open and rinse slowly and gently with water for 15-

20 minutes. Remove contact lenses, if present, after the first 5 minutes,

then continue rinsing eye. Call a poison control center or doctor for

treatment advice.



SKIN CONTACT: Remove contaminated clothing. Rinse skin immediately with

plenty of water for 15-20 minutes. If redness, itching, burning or other

symptoms develop or persist, get medical attention promptly. Wash

contaminated clothing before reuse.



INHALATION: Move person to fresh air. If breathing has stopped, call 911

or an ambulance, then give artificial respiration, preferably mouth-to-

mouth. Call a poison control center or doctor for further treatment

advice.



INGESTION: Immediately call a poison control center or doctor for

treatment advice. Do not induce vomiting unless told to do so by a poison

control center or doctor. Do not give any liquid to the person. Do not

give anything by mouth to an unconscious person.



NOTE TO PHYSICIAN: There is no specific antidote for effects from

overexposure to this material. Treatment should be directed at the control

of symptoms and the clinical condition.

FLASH POINT: None

AUTOIGNITION TEMPERATURE: No information found

FLAMMABLE LIMITS (% volume/air)

  Lower Limit: Not applicable

  Upper Limit: Not applicable



EXTINGUISHING MEDIA: Product is non-flammable as supplied.      Use water,

foam, carbon dioxide or dry chemical to extinguish fire.



                               Wear self-contained breathing apparatus while

FIRE FIGHTING PROCEDURES:

extinguishing fire.



FIRE AND EXPLOSION HAZARDS: Product is non-flammable as supplied. Do not

depend on ambient air for breathing air supply during fires. Fire may

result into releases of toxic gases such as oxides of carbon, nitrogen and

sulfur.



                           6 SPILL AND LEAK PROCEDURES



Soak up spills with absorbent material and scoop into drums. Follow all

local, state, and federal regulations for disposal. Keep spills out of

municipal sewers and open bodies of water. Do not discharge into lakes or

streams. The floor may be slippery. Use caution to avoid falls.

                              7 HANDLING AND STORAGE



HANDLING: Avoid breathing vapors, mists or fumes. Avoid contact with skin

or eyes. Observe good personal hygiene practices and recommended

procedures. Wash thoroughly after handling.



STORAGE: Keep in a closed, labeled container within a cool (well-shaded),

dry, ventilated area. Protect from physical damage. Keep containers

closed when material is not in use. Maintain good housekeeping. Keep from

freezing.

                   8 EXPOSURE CONTROLS/PERSONAL PROTECTION



                           Provide sufficient general/local exhaust

ENGINEERING CONTROLS:

ventilation.



RESPIRATORS: Not required under normal use conditions. If ventilation is

inadequate to maintain personal inhalation exposures below TLV (PEL), use

appropriate MSHA/NIOSH approved respiratory protection to comply with

current 29 CFR 1910.134 and manufacturer's "Instructions" and "Warnings".



OTHER CLOTHING: Industrial safety glasses, long sleeves, long pants, and

boots. Use side shields, goggles and/or faceshield if splashing is

possible. As required, chemical-resistant flexible-type gloves (neoprene,

PVC, butyl, nitrile or equal).

Ethylene Thiourea is considered a reasonably anticipated carcinogen by the

National Toxicology Program (NTP)based on liver, thyroid, and lymphatic

system tumors in animals.



Overall evaluation of ethylene thiourea resulted in a downgrade by IARC to

Group 3 (not classifiable as to carcinogenicity in humans) on the basis of

mechanistic data. (2001)



     Oral LD50        - Rats                     1.4 gm/kg

     Dermal LD50      - Rabbits                  >2.0 gm/kg

                            12 ECOLOGICAL DATA



This product is toxic to fish. Do not discharge effluent containing this

product into lakes, streams, ponds, estuaries, oceans or other waters

Discharge Elimination System (NPDES) permit.

                           13 DISPOSAL CONSIDERATIONS



Do not contaminate water, food, or feed by storage or disposal. Pesticide

wastes are toxic. Improper disposal of excess pesticide, spray mixture, or

rinsate is a violation of federal law. If these wastes cannot be disposed

of by use according to label instruction, contact your State Pesticide or

Environmental Control Agency, or the hazardous waste representative at the
