2. COMPOSITION/INFORMATION ON INGREDIENTS
Specific chemical identity of ingredients withheld as proprietary information. Refer to remaining sections for information
concerning the properties and effects of ingredients.
3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Appearance and Odor: Tan powder, with no distinct odor.
POTENTIAL HEALTH EFFECTS
INGESTION: Small doses may cause mild discomfort. Used as a general purpose food additive and potable water additive.
INHALATION: Slight discomfort possible. Causes readily reversible changes which disappear after end of exposure. Dust may
cause further aggravation to those predisposed to respiratory problems.
EYE CONTACT: Slight eye abrasion possible.
SKIN CONTACT: Slight abrasion possible.
SKIN ABSORPTION: Prolonged contact may cause slight skin abrasion.
EFFECTS OF OVERDOSE: One reference lists that massive doses ingested or large doses administered under the skin, or in
the blood stream, may cause diarrhea, and there arises the possibility of sufficient absorption to produce diuresis and systemic

ammonia poisoning. Another reference lists unknown鈥攏o information on humans considered valid by authors.
4. FIRST AID MEASURES
IF IN EYES OR ON SKIN, wash exposed areas with water. Flush eyes with running water for 15 minutes. Immediate first aid is
not likely to be required, but seek medical attention if condition persists. Wash skin with mild soap and water. Seek medical
condition if condition persists.
IF INHALED, immediate first aid is not likely to be required. Should cause no problems by inhalation. However, if symptoms
occur, remove to fresh air. Remove material from eyes, skin and clothing.
IF SWALLOWED in large amount, give 2-3 glasses of water and induce vomiting. Call a doctor.
5. FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA: Used in a solution as a fire retardant and to fight fires. Use media suitable to extinguish source of
fire.
SPECIAL FIRE FIGHTING PROCEDURES: Use media suitable to extinguish source of fire.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Releases NH3 and Sulfur Oxides when decomposing. If accidentally mixed
with oxidizers it will sensitize these materials and make them more reactive under fire conditions.
FLASH POINT (Test Method): Non-flammable Flammable Limits LOWER UPPER
6. ACCIDENTAL RELEASE
ENVIRONMENTAL PRECAUTIONS: Keep out of waterways and all bodies of water. Do not contaminate any body of water by
direct application, cleaning of equipment or disposal. Since WSU Ammonium Sulfate is a fertilizer, it may promote algae growth
in waterways.
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Contain spill. Sweep up and scoop dry material into
suitable container for use or recycle. Mop up and absorb liquid and dispose of into suitable container for use or recycle. May be
used as a fertilizer using good agronomic practices.
7. HANDLING AND STORAGE
HANDLING: HANDLE IN ACCORDANCE WITH GOOD INDUSTRIAL HYGIENE AND SAFETY PRACTICES. THESE
PRACTICES INCLUDE AVOIDING UNNECESSARY EXPOSURE AND REMOVAL OF MATERIAL FROM EYES, SKIN, AND
CLOTHING. Avoid prolonged contact with skin. Use dust mask if material is dry and dusty.
STORAGE: Store in a cool, dry place to maintain product performance. SEPARATE FROM STRONG OXIDIZERS SUCH AS
CHLORATES, NITRATES AND NITRITES.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
EYE PROTECTION: Where there is potential for eye contact, wear goggles with side shield and have eye flushing equipment
immediately available.
SKIN PROTECTION: Wear appropriate protective clothing and chemical resistant gloves to prevent skin contact.
RESPIRATORY PROTECTION: Use dust mask if material is in dry form and dusty.
VENTILATION: Provide adequate ventilation for bulk storage.
