Keep affected person warm and at rest. Treat symptomatically and supportively. Administration of oxygen should be performed by qualified personnel. Get medical attention immediately. Upon contact with the skin, damage including redness, cutaneous burns, skin fissures and white eschars may occur without immediate pain.
Alkalies penetrate the skin slowly.
The extent of injury depends on the duration of contact. If sodium hydroxide is not removed from the skin, severe burns with deep ulceration may occur. Exposure to the dust or mist may cause multiple small burns and temporary loss of air. Pathologic findings due to alkalies may include gelatinous, necrotic areas at the site of contact. Effects are dependent upon concentration and duration of exposure.
