Have victim rinse mouth with water again. First Aid Comments: All first aid procedures should be periodically reviewed by a doctor familiar with the chemical and its conditions of use in the workplace.
Suitable Extinguishing Media: Not combustible. Use extinguishing agent suitable for surrounding fire. Specific Hazards Arising from the Chemical: Contact with water causes violent frothing and spattering. Reacts with metals to produce highly flammable hydrogen gas. Closed containers may rupture violently when heated releasing contents. Toxic sodium oxide fumes can be generated at high temperatures. Personal Precautions: Evacuate the area immediately.
Isolate the hazard area. Keep out unnecessary and unprotected personnel. Use personal protective equipment as required. Remove or isolate incompatible materials as well as other hazardous materials. Methods for Containment and Clean-up : Contain and soak up spill with absorbent that does not react with spilled product. Shovel or sweep dry sodium hydroxide for recycling or disposal. Flush spill area. Dike spilled product to prevent runoff. Handling: Before handling, it is important that all engineering controls are operating and that protective equipment requirements and personal hygiene measures are being followed.
Only trained personnel should work with this product. Immediately report leaks, spills or failures of the safety equipment e. Avoid generating vapours or mists. Avoid generating dusts. Use corrosion-resistant tools and equipment. Never add water to a corrosive.
Always add corrosives slowly to COLD water. Never reuse empty containers, even if they appear to be clean. Keep containers tightly closed when not in use or empty. Storage: Store in an area that is: cool, dry, well-ventilated, separate from incompatible materials. Keep amount in storage to a minimum. Store in the original, labelled, shipping container. Vent drums to prevent pressure buildup. Do not handle swollen drums. Get expert advice. Empty containers may contain hazardous residue.
Store separately. Keep closed. Contain spills or leaks by storing containers in trays made from compatible materials. Sodium hydroxide is corrosive. NaOH can react with moisture from the air and may generate heat as it dissolves. This heat can be enough to cause a fire if it is near flammable materials. Sodium hydroxide is useful for its ability to alter fats. It is used to make soap and as a main ingredient in household products such as liquid drain cleaners. Sodium hydroxide is usually sold in pure form as white pellets or as a solution in water.
Sodium hydroxide is used in bar soaps and detergents. Sodium Hydroxide is also used as a drain cleaner to unclog pipes. Some other uses include fuel cell production, to cure food, to remove skin from vegetables for canning, bleach, drain cleaner, oven cleaner, soaps, detergent, paper making, paper recycling, aluminum ore processing, oxide coating, processing cotton fabric, pickling, pain relievers, anticoagulants to prevent blood clots, cholesterol reducing medications, and water treatment.
In the home, some household items like soaps or cleaners contain sodium hydroxide. Accidental ingestion or skin contact with these cleaners could cause harmful exposure.
Some industrial workplaces use sodium hydroxide. Here are some workplace exposure limits to NaOH in the air. Remove clothes carefully if they get wet to avoid spreading the sodium hydroxide on your skin. Sodium hydroxide is a potentially dangerous substance. It can hurt you if it touches your skin, if you drink it or if you breathe it. Eating or drinking sodium hydroxide can cause severe burns and immediate vomiting, nausea, diarrhea or chest and stomach pain, as well as swallowing difficulties.
Damage to the mouth, throat and stomach is immediate. Breathing it can cause severe irritation of the upper respiratory tract with coughing, burns and difficulty breathing.
The harmful effects of sodium hydroxide depend on several factors including the concentration of sodium hydroxide, length of time exposed, and whether you touched it, drank it or inhaled it. Contact with very high concentrations of sodium hydroxide can cause severe burns to the eyes, skin, digestive system or lungs, resulting in permanent damage or death.
Prolonged or repeated skin contact may cause dermatitis. Repeated inhalation of sodium hydroxide vapor can lead to permanent lung damage. Sodium hydroxide is also used to refine raw materials for wood products such as cabinets and furniture and in wood bleaching and cleaning. Sodium hydroxide is used to extract alumina from naturally occurring minerals. Alumina is used to make aluminum and a variety of products including foil, cans, kitchen utensils, beer kegs and airplane parts.
In building and construction, aluminum is used in materials that enable building facades and window frames. Sodium hydroxide is used in many other industrial and manufacturing processes. It is used to manufacture rayon, spandex, explosives, epoxy resins, paints, glass and ceramics.
It is also used in the textile industry to make dyes, process cotton fabric and in laundering and bleaching, as well as in metal cleaning and processing, oxide coating, electroplating and electrolytic extracting. Due to its strong corrosive qualities, exposure to sodium hydroxide in its solid or solution form can cause skin and eye irritation , according to the U. Workers in facilities where sodium hydroxide is manufactured or used should follow product safety instructions.
The U. The National Institute for Occupational Safety and Health provides general safety information about transporting sodium hydroxide, including guidance on packaging and storage, spillage, disposal, and packaging and labeling for workers. Sodium hydroxide is a highly versatile substance used to make a variety of everyday products, such as paper, aluminum, commercial drain and oven cleaners, and soap and detergents. Sodium hydroxide, also known as caustic soda or lye, is a highly versatile substance used in a variety of manufacturing processes to make other products like paper or aluminum, for example.
