Hazard Symbols:
Risk Phrases:
					

Appearance: White hydroscopic solid

DANGER! CORROSIVE. POISON! MAY BE FATAL IF ABSORBED THROUGH THE SKIN. MAY BE FATAL IF SWALLOWED. CAUSES DIGESTIVE AND RESPIRATORY TRACT BURNS. CAUSES SEVERE EYE AND SKIN BURNS.

Target Organs: None.

Potential Health Effects:

Eye:

Causes severe eye burns.

Skin:

May be fatal if absorbed through the skin. Causes skin burns. May cause deep, penetrating ulcers of the skin.

Ingestion:

Harmful if swallowed. Causes gastrointestinal tract burns. Causes severe pain, nausea, vomiting, diarrhea, and shock.

Inhalation:

Irritation may lead to chemical pneumonitis and pulmonary edema. Causes severe irritation of upper respiratory tract with coughing, burns, breathing difficulty, and possible coma.

Chronic:

Prolonged or repeated skin contact may cause dermatitis.

Eyes:

Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Get medical aid immediately.

Skin:

Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Discard contaminated clothing in a manner which limits further exposure.

Ingestion:

Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.

Inhalation:

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.

Notes to Physician:

Treat symptomatically and supportively.

Antidote:

None reported.

General Information:

Wear appropriate protective clothing to prevent contact with skin and eyes. Wear a self-contained breathing apparatus (SCBA) to prevent contact with thermal decomposition products. Use water with caution and in flooding amounts. Contact with moisture or water may generate sufficient heat to ignite nearby combustible materials.

Extinguishing Media:

For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam.

Autoignition Temperature:

Not applicable.

Flash Point:

Not applicable.

NFPA Rating:

Explosion Limits:

Lower: Not available
Upper: Not available

General Information:

Use proper personal protective equipment as indicated in Section 8.

Spills/Leaks:

Vaccuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions.

Handling:

Wash thoroughly after handling. Use with adequate ventilation. Do not allow water to get into the container because of violent reaction. Do not get in eyes, on skin, or on clothing. Do not ingest or inahale.

Storage:

Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from strong acids. Keep away from water. Keep away from metals. Keep away from flammable liquids. Keep away from organic halogens.

Storage Code:

No information available.

Engineering Controls:

Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.

Eyes:

Wear safety glasses and chemical goggles or a face shield if handling liquids.

Skin:

Wear impervious gloves.

Clothing:

Wear appropriate protective clothing to prevent skin exposure.

Respirators:

A NIOSH/MSHA approved air purifying dust or mist respirator.

Chemical Stability:

Stable.

Conditions to Avoid:

Incompatible materials, moisture, contact with water, acids.

Incompatibilities with Other Materials

Generates large amounts of heat when in contact with water and may steam and splatter. Reacts with mineral acids to form corresponding salts; reacts with weak acids gases like hydrogen sulfide, sulfur dioxide, and carbon dioxide; ignites when in contact with cinnamaldehyde or zinc; and reacts explosively with a mixture of chloroform and methane. Corrosive to metals such as aluminum, tin, and zinc as well as to alloys such as steel, and may cause formation of flammable hydrogen gas.

Hazardous Decomposition Products

Toxic fumes of sodium oxide, sodium peroxide fumes.

Hazardous Polymerization

Has not been reported.

RTECS:

LD50/LC50

No information available.

Carcinogenicity:

CAS# 1310-73-2: Not listed as a carcinogen by ACGIH, IARC, NIOSH, NTP, OSHA, or CA Prop 65.

Epidemiology:

No information reported.

Teratogenicity:

No information reported. No information reported.

Mutagenicity

Mutation data reported.

Neurotoxicity

No information reported.

Ecotoxicity:

TLm, mosquito fish, 125 ppm/96hr. (fresh water); TLm, bluegill, 99 mg/48hr. (tap water).

Environmental:

This chemical is not mobile in solid form, although it absorbs moisture very easily. Once liquid, sodium hydroxide leaches rapidly into the soil, possibly contaminating water sources.
