Ingredient CAS No Percent Hazardous
--------------------------------------- ------------ ------------ ---------
Sodium Sulfate 7757-82-6 98 - 100% Yes
Inhalation: Not expected to be a health hazard.
Ingestion: Mildly toxic by ingestion. Systemic toxicity is unlikely
unless massive amounts have been swallowed. Drinking water with > 500 mg/L
may result in gastrointestinal irritation.
Skin Contact: No adverse effects expected.
Eye Contact: No adverse effects expected but dust may cause mechanical
irritation.
Chronic Exposure: No information found.
Aggravation of Pre-existing Conditions: No information found.
Inhalation: Not expected to require first aid
measures.
Ingestion: Give several glasses of water to drink to dilute. If large
amounts were swallowed, get medical advice.
Skin Contact:
Eye Contact: Wash thoroughly with running water. Get medical advice if
irritation develops.
Fire: Not considered to be a fire hazard.
Explosion: Not considered an explosion hazard, but violent explosions
occur when potassium sulfate and sodium sulfate are melted with aluminum.
Fire Extinguishing Media: Use any means suitable for extinguishing
surrounding fire.
Special Information: Use protective clothing and breathing equipment
appropriate for the surrounding fire.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits: None established.
Ventilation System: In general, dilution ventilation is a satisfactory
health hazard control for this substance. However, if conditions of use create
discomfort to the worker, a local exhaust system should be considered.
Personal Respirators (NIOSH Approved): For conditions of use where
exposure to dust or mist is apparent and engineering controls are not feasible,
a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil
particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a
NIOSH type R or P filter. For emergencies or instances where the exposure levels
are not known, use a full-face positive-pressure, air-supplied respirator.
WARNING: Air-purifying respirators do not protect workers in oxygen-deficient
atmospheres.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain
and quick-drench facilities in work area.
Appearance: White efflorescent crystals or granules.
Odor: Odorless.
Solubility: Soluble in 1.5 parts of water @ 25C (77F).
Specific Gravity: 1.46
pH: Aqueous solution is neutral.
% Volatiles by volume @ 21C (70F): 0
Boiling Point: No information found.
Melting Point: 32C (90F) Loses water at 100C (212F). Anhydrous melts ca.
844C (1551F)
Vapor Density (Air=1): No information found.
Vapor Pressure (mm Hg): No information found.
Evaporation Rate (BuAc=1): No information found.
Stability: Stable under ordinary conditions of use
and storage. Effloresces in dry air.
Hazardous Decomposition Products: Oxides of sulfur and sodium may form
when heated to decomposition.
Hazardous Polymerization: Will not occur.
Incompatibilities: In combination with sodium sulfate, aluminum and
magnesium will explode @ 800C (1472F); strong mineral acids and bases.
Conditions to Avoid: Air, incompatibles.
Investigated as a tumorigen, mutagen, reproductive effector. No LD50/LC50 information found relating to normal routes of occupational exposure.

Environmental Fate: When released into the soil,
this material is expected to leach into groundwater. This material is not
expected to significantly bioaccumulate.
Environmental Toxicity: This material is not expected to be toxic to
aquatic life. The LC50/96-hour values for fish are over 100 mg/l. The
EC50/48-hour values for daphnia are over 100 mg/l.
Whatever cannot be saved for recovery or recycling should be managed in an appropriate and approved waste disposal facility. Processing, use or contamination of this product may change the waste management options. State and local disposal regulations may differ from federal disposal regulations. Dispose of container and unused contents in accordance with federal, state and local requirements.
Not regulated.
