Section V: HEALTH HAZARD INFORMATION
V 1: ROUTE OF ENTRY:
EYE : Irritant in sensitive persons
Skin Contact : May cause discomfort depending on temperature.
Skin Absorption : : May cause temporary wrinkling of skin.
Inhalation : Inhalation of liquid can be fatal.
Ingestion : Ingestion of large quantities may result in excessive micturation.
V 2: EFFECTS OF OVEREXPOSURE:
Acute Exposure : Inhalation of liquid can cause serious discomfort, possible tissue damage and is often fatal.
Chronic Exposure: Not known to cause permanent effects other than excessive micturation due to large amounts be-
ing ingested..
V 3: PERMISSIBLE EXPOSURE LIMITS:
(See also above under "INGREDIENTS ----- HAZARD CLASSIFICATIONS".)
V 4: TOXICITY DATA
Eyes : May be an irritant to eyes.
Material Safety Data Sheet:- DIHYDROGEN MONOXIDE Page No. 4 of 5. - - 1/7/2008.
V 4: TOXICITY DATA (Continued)
Skin : Has been known to cause temporary wrinkling of skin.
Other : Inhalation of liquid can cause serious discomfort, possible tissue damage and is often fatal.
V 5: EMERGENCY FIRST AID
EYES: In case of contact if irritation occurs, flush with normal saline solution. Seek medical attention if
condition persists.
INGESTION: If swallowed, do not induce vomiting. The patient is the best judge of what help is needed.
INHALATION: In case of excessive respiratory exposure to liquid, remove to fresh air, apply artificial respiration
and/or CPR if patient is not breathing spontaneously and/or has no detectible pulse.
SKIN: In case of contact, remove excess with soft absorbent material. Contaminated clothing should be
removed and dried before reuse. Keep exposed persons warm if chilled.
Section VI: REACTIVITY DATA
STABILITY: Generally considered stable
CONDITIONS TO AVOID: All drying agents such as Sulfuric acid, most concentrated (dry) active chemicals such as
caustic soda and active metals such as Sodium or Potassium.
INCOMPATIBILITY: May cause corrosion of ferrous alloys. Avoid contact with all electrical equipment.
HAZARDOUS DECOMPOSITION PRODUCTS: Does not decompose.
HAZARDOUS POLYMERIZATION: Will not occur except at low temperatures. This material expands on freezing
and should never be stored on rigid containers near, at or below the freezing temperature of 273.16 Kelvins.
Section VII: SPILL MANAGEMENT
Reportable Quantities (in lb.) for Title III: Not Regulated
Steps to Be taken in case of a spill or release: Contain release as much a possible. Divert to proper disposal
areas whenever possible.
Waste Disposal Method: Dispose in accordance with all local, State and Federal regulations. Special
conditions may be imposed by local utilities.

Section VIII: HANDLING AND STORAGE
Depending on circumstances and possible dissolved or suspended contaminants it may be advisable to wash thoroughly
after handling. Do not get in eyes, on skin or clothing.
Do not breathe liquid. Keep container closed when not in use. Minimizing contact with this and all chemicals is recom-
mended as a good general policy to follow.
Store in a cool to cold place. Re-close containers when not in use. Avoid Freezing except in specially designed contain-
ers.
