Get medical aid immediately. Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth respiration 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.

Skin

Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.

Eyes

Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Inhalation

May cause effects similar to those described for ingestion.

Skin

May cause irritation and dermatitis.

Eyes

May cause eye irritation.

Ingestion

Harmful if swallowed. Ingestion of large amounts may cause systemic effects such as nausea, stomach pain, rapid breathing, sweating, convulsions, coma, cardiovascular collapse and possible death. May cause nausea, vomiting, and diarrhea, possibly with blood. May cause wakefulness and restlessness, irritability, excitement, rapid heart rate, ringing in the ears, anorexia, muscle spasms and convulsions, gastrointestinal irritation, headache, dizziness, seizures, dehydration and fever.

Exposure Controls/Personal Protection

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves and clothing to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.

Respirators

Exposure Effects

Rapid heart rate is common, abnormally low blood pressure occurs with severe overdose. Tremors are common. Restlessness, agitation, hallucinations and headache may occur. Seizures may be focal.

Fire Fighting Measures

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.

Accidental Release Measures

Small spills/leaks

Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity

Stability

Stable under normal temperatures and pressures. Absorbs carbon dioxide from the air. Unstable in acid solution.

Incompatibilities

Strong oxidizing agents, acids, air.

Decomposition

Nitrogen oxides, carbon monoxide, carbon dioxide.
