- 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.

- Soda Ash Dense – 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.

- Soda Ash Dense – 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”.

- 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.
- Soda Ash Dense – 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 NIOSH/MSHA, EU CEN or comparable certification organization to protect them against airborne 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 breating 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)
