At room temperature, anhydrous sodium hydroxide is a white crystalline, odorless solid that absorbs moisture from the air. It is produced as flakes, pellets, sticks, and cakes. When dissolved in water or neutralized with acid, it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is caustic and is ...
Inhalation of sodium hydroxide dust, mist, or aerosol may cause irritation of the mucous membranes of the nose, throat, and respiratory tract. Sodium hydroxide is odorless; thus, odor provides no warning of hazardous concentrations. Mucous membrane irritation occurs at the OSHA PEL (2 mg/m3) and is generally an adequate warning property for acute e...
Sodium hydroxide is produced by the electrolysis of aqueous solutions of sodium chloride (brine) or by reacting naturally occurring sodium carbonate with calcium hydroxide. Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching...
OSHA PEL (permissible exposure limit) = 2 mg/m3(averaged over an 8-hour workshift) NIOSH IDLH (immediately dangerous to life or health) = 10 mg/m3 AIHA ERPG-2 (emergency response planning guideline) (maximum airborne concentration below which it is believed that nearly all individuals could be exposed for up to 1 hour without experiencing or develo...
Description: Colorless-to-white, odorless, solid that absorbs moisture from the air. Warning properties: Inadequate; no odor. Mucous membrane irritation at 2 mg/m3. Molecular weight: 40.0 daltons Boiling point(760 mm Hg): 2,534°F (1,390°C) Freezing point: 605°F (318°C) Specific gravity: 2.13 (water = 1) Vapor pressure: 0 mm Hg at 68°F (20°C) Water ...
Sodium hydroxide dissolves easily in water generating a great deal of heat. It reacts with acids (also generating a lot of heat); halogenated organic compounds; metals such as aluminum, tin, and zinc; and nitromethane. Sodium hydroxide is corrosive to most metals.
Sodium hydroxide is strongly irritating and corrosive. It can cause severe burns and permanent damage to any tissue that it comes in contact with. Sodium hydroxide can cause hydrolysis of proteins,...Inhaled sodium hydroxide can cause swelling of the larynx and an accumulation of fluid in the lungs.Stridor, vomiting, drooling, and abdominal pain are early symptoms of sodium hydroxide ingestion. Ingestion may lead to perforation of the gastrointestinal tract and shock.Sodium hydroxide does not produce systemic toxicity; its health effects are due to its corrosive nature.Sodium hydroxide is strongly irritating and corrosive. It can cause severe burns and permanent damage to any tissue that it comes in contact with. The extent of damage to the gastrointestinal tract may not be clear until several hours after ingestion. Inhaled sodium hydroxide can cause swelling of the larynx and an accumulation of fluid in the lung...
Chronic exposure to dusts or mists of sodium hydroxide may lead to ulceration of the nasal passages. Chronic skin exposures can lead to dermatitis. Ingestion may lead to perforation of the gastrointestinal tract or stricture formation. Chronic exposure may be more serious for children because of their potential longer latency period.
Sodium hydroxide dissociates within the body and would not reach the reproductive organs in an unchanged state. No data were located concerning reproductive endpoints in humans exposed to sodium hydroxide. Sodium hydroxide is not teratogenic in rats. Sodium hydroxide is not included in Reproductive and Developmental Toxicants, a 1991 report publish...

Oct 14, 2022 · Safety Information. 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.S. Centers for Disease Control and Prevention Agency for Toxic Substances and Disease Registry.
Sodium hydroxide (NaOH) has no smell. It is made of solid white crystals that absorb water from the air. Sodium hydroxide is caustic. Sodium hydroxide can harm workers who come in contact with it. The level of harm depends upon the amount, duration, and activity. It can burn the eyes, skin, and inner membranes, and cause temporary hair loss.
The Occupational Safety and Health Administration (OSHA) sets a limit of 2 milligrams of sodium hydroxide per cubic meter of air (2 mg/m 3) in the workplace for an 8-hour work shift, 40-hour work week. The Food and Drug Administration (FDA) allows sodium hydroxide as a food additive in levels not to exceed 1%.
