2. HAZARDS IDENTIFICATION



EMERGENCY OVERVIEW:

White, odorless, granular solid.

Product is non-combustible.

Reacts with acids to release carbon dioxide gas and heat.

Irritating to the eyes and continuous contact may irritate the skin.

Not expected to be toxic to the environment, nor to aquatic organisms.



POTENTIAL HEALTH EFFECTS:

Direct contact with the product causes irritation of the eyes and continuous

contact may cause skin irritation (red, dry, cracked skin). Excessive levels

of airborne dust may irritate the mucous membranes and upper respiratory

tract.



3. COMPOSITION / INFORMATION ON INGREDIENTS



Chemical Name CAS# Wt.% EC No. EC Class

Sodium carbonate 497-19-8 99.8 207-838-8 Xi, R36



4. FIRST AID MEASURES



EYES:

Immediately flush with water for at least 15 minutes, lifting the upper and

lower eyelids intermittently. See a medical doctor or ophthalmologist as

necessary.



SKIN:

Wash with plenty of soap and water. Get medical attention if irritation

occurs and persists.



INGESTION:

Rinse mouth with water. Dilute by giving 1 or 2 glasses of water. Do not

induce vomiting. Never give anything by mouth to an unconscious person.

See a medical doctor immediately.



INHALATION:

Remove to fresh air. If breathing difficulty or discomfort occurs and

persists, obtain medical attention.

NOTES TO MEDICAL DOCTOR:

While internal toxicity is low, irritant effects of high concentrations may

produce corneal opacities, and vesicular skin reactions in humans with

abraded skin only. Treatment is symptomatic and supportive.



5. FIRE FIGHTING MEASURES



EXTINGUISHING MEDIA:

Water, water fog, carbon dioxide (CO2), dry chemical



FIRE / EXPLOSION HAZARDS: Not applicable



FIRE FIGHTING PROCEDURES:

Wear full protective clothing and self-contained breathing apparatus.



FLAMMABLE LIMITS:

Not applicable



HAZARDOUS COMBUSTION PRODUCTS:

Fumes of sodium oxide.



SENSITIVITY TO IMPACT: None

SENSITIVITY TO STATIC DISCHARGE: None



6. ACCIDENTAL RELEASE MEASURES



COMMENTS:

PERSONAL PRECAUTIONS: Refer to Section 8 "Exposure Controls / Personal

Protection".



CONTAINMENT:

Prevent large quantities of this product from contacting vegetation or

waterways; large spills could kill vegetation and fish.



CLEAN-UP:

This product, if spilled, can be recovered and re-used if contamination does

not present a problem. Vacuum or sweep up the material. If the spilled

product is unusable due to contamination, consult state or federal

environmental agencies for acceptable disposal procedures and locations.

See Section 13 "Disposal Considerations".



NOTIFICATION REQUIREMENTS:

Federal regulations do not require notification for spills of this

product. State and local regulations may contain different requirements;

consult local authorities.



7. HANDLING AND STORAGE



HANDLING:

Use air conveying / mechanical systems for bulk transfer to storage. For

manual handling o bulk transfer use mechanical ventilation to remove airborne

dust from rail car, ship or truck. Use approved respiratory protection when

ventilation systems are not available. Selection of respirators is based

on the dust cloud generation. Keep material out of lakes, streams, ponds and

sewer drains.



STORAGE:

Store in a cool dry area, away from acids.



8. EXPOSURE CONTROLS / PERSONAL PROTECTION



ENGINEERING CONTROLS:

Where possible, provide general mechanical and/or local exhaust ventilation

to prevent release of airborne dust into the work environment.



PERSONAL PROTECTIVE EQUIPMENT

EYES AND FACE:

Appropriate eye and face protection equipment (ANSI Z87 approved) should be

selected for the particular use intended for this material. Safety glasses

with side shields are recommended.



RESPIRATORY:

Whenever dust in the worker's breathing zone cannot be controlled with

ventilation or other engineering means, workers should wear respirators or

dust masks approved by dust.



PROTECTIVE CLOTHING:

Dry product is generally non-irritating to intact skin. However, this product

can be irritating where skin has been damaged and can create skin irritation

after long exposures when moisture is present. Under such conditions, gloves

and long-sleeved clothing are recommended to minimize skin contact.



COMMENTS:

ADDITIONAL EXPOSURE GUIDELINES:

Federal guidelines treat the ingredient(s) in this product as a nuisance dust,

as no product-specific guidelines have been issued for exposure. As with all

nuisance dusts, worker breathing zone concentrations should be measured by

validated sampling and analytical methods. The following limits (OSHA and

MSHA) apply to this material:



Particulates Not Otherwise Regulated:

OSHA (PEL / TWA): 15 mg/m3 (total dust); 5 mg/m3 (resp fraction)

MSHA (PEL / TWA): 10 mg/m3 (total dust)



The information noted above provides general guidance for handling this

product. Specific work environments and material handling practices will

dictate the selection and use of personal protection equipment (PPE).
