Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: yellow solid.
Danger! Toxic if swallowed. Danger of serious damage to health by prolonged exposure through inhalation. May be fatal if inhaled. Causes burns by all exposure routes. Strong oxidizer. Contact with other material may cause a fire. May impair fertility. May cause harm to the unborn child. Harmful if absorbed through the skin. Cancer hazard. Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. May cause heritable genetic damage. May cause sensitization by inhalation and by skin contact. Hygroscopic (absorbs moisture from the air).
Target Organs: Blood, kidneys, liver, respiratory system, gastrointestinal system, eyes, skin.


Potential Health Effects
Eye: Causes eye burns.
Skin: Harmful if absorbed through the skin. Causes skin burns. May cause sensitization by skin contact.
Ingestion: Causes gastrointestinal tract burns. Toxic if swallowed.
Inhalation: May be fatal if inhaled. Causes chemical burns to the respiratory tract. May cause respiratory sensitization.
Chronic: May cause cancer in humans. Repeated or prolonged exposure may cause allergic reactions in sensitive individuals. Possible risk of harm to the unborn child. May impair fertility.

Section 4 - First Aid Measures


Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid imme diately.
Skin: Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: Do not induce vomiting. Get medical aid immediately. Call a poison control center.
Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
Notes to Physician: Treat symptomatically and supportively.
