**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Harmful if swallowed. May cause harm to the unborn child.

Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May cause allergic sensitization in certain
individuals.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed. Rapidly absorbed when
ingested and disseminated throughout the body.
Inhalation:
Causes irritation of the mucous membrane and upper respiratory
tract.
Chronic:
Possible cancer hazard based on tests with laboratory animals.
Laboratory experiments have resulted in mutagenic effects. May be
rapidly transferred across the placenta and cause adverse fetal
effects.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. This
material in sufficient quantity and reduced particle size is capable
of creating a dust explosion.
Extinguishing Media:
Use agent most appropriate to extinguish fire. Use water spray, dry
chemical, carbon dioxide, or appropriate foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Minimize dust
generation and accumulation. Avoid breathing dust, vapor, mist, or
gas. Avoid contact with eyes, skin, and clothing. Keep container
tightly closed. Avoid ingestion and inhalation. Wash clothing before
reuse.
Storage:
Keep container closed when not in use. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 96-45-7:

Netherlands: 0.024 mg/m3 MAC

Personal Protective Equipment

Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant respirator use.

testIf released to soil, 2-Imidazolidinethione is readily degraded
with half-lives of less than one week observed under field
conditions. Although soil microorganisms can degrade
2-Imidazolidinethione, degradation in soil may be accomplished by
chemical conversion to ethyleneurea followed by microbial attack. It
is expected to be highly mobile in most wet soils with the exception
of soils with high organic content. Strong adsorption and/or
