First Aid Measures
Emergency procedures for chemical exposure incidents
Remove person to fresh air and keep comfortable for breathing. If not breathing, give artificial respiration. If breathing is difficult administer oxygen. Seek medical attention.
Immediately remove contaminated clothing. Flush skin with water for at least 15 minutes. Seek immediate medical attention.
Symptoms: burns to skin
Immediately flush eyes with large amounts of water, holding lids apart to ensure rinsing of entire surface. Continue rinsing for at least 15 minutes. Remove contact lenses, if present and easy to do. Washing eyes within several seconds of contact is essential to achieve maximum effectiveness. Get immediate medical attention.
Symptoms: burns to eyes
Do not induce vomiting. If victim is conscious, rinse mouth, give water. Never give anything by mouth to an unconscious person. Seek immediate medical attention.
Symptoms: burns to mouth, throat, tissue damage, abdominal pain, nausea, vomiting, collapse
Immediate Medical Attention
Seek medical attention.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Material is not flammable. Use extinguishing media suitable to surrounding materials.
Extinguish all ignition sources. Hydrogen gas may be liberated from contact with amphoteric metals (such as aluminum)
Use water to cool nearby containers and structures.
Firefighter Protection
Wear full protective equipment, including suitable respiratory protection.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Prevent spread of spill. Wear full protective equipment, including a complete protective suit and an appropriate respirator depending upon the size of the spill. Absorb with sand or inert material. Sweep or scoop into a disposal container. Carefully neutralize residue with a dilute, inorganic acid solution. Flush spill area with water.

Handling and Storage
Safe handling precautions, storage conditions, and workplace requirements
Do not breathe dusts or mists. Wash thoroughly after handling. Wear protective gloves, protective clothing, eye protection, face protection. When mixing with water, always add caustic slowly to the water, never add water to concentrated caustic.
Store locked up in a cool, dry, well-ventilated corrosive materials storage area away from incompatible materials. Keep containers tightly closed and protect them from physical damage. Protect from moisture. Store above the freezing point of the material (approximately 60°F). Do not store in metal containers. Keep only in original container.
Wash thoroughly after handling.
Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Use general or local exhaust ventilation to meet TLV and PEL requirements.
chemical-resistant gloves
Safety goggles, face shield
Respiratory protection required if airborne concentrations exceed PEL or TLV. Use a NIOSH approved respirator with a particulate filter.
protective clothing appropriate for the risk of exposure
