It is combustible though it may require some effort to ignite.
Containers may explode when heated.
Toxic oxides of nitrogen may form in fires.
Rapid heart rate, elevated blood pressure, rapid breathing, and elevated body temperature may be seen. In severe cases, respiratory paralysis (apnea) with low heart rate, abnormally low blood pressure, and cardiac arrest may occur. Seizures - symptoms may occur within 15 minutes and might include agitation, hypertonicity of muscles, opisthotonos, seizures, and painful muscle spasms. The patient usually remains alert throughout the seizures. Auditory, tactile, or visual stimulation may produce a violent motor response. Chief effects are dictated by the most powerful muscle acting on that joint.
May cause irritation of the digestive tract. Poison by ingestion. May cause tremors and convulsions.
May cause respiratory tract irritation. May cause effects similar to those described for ingestion.
May cause skin irritation.
May cause eye irritation.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately. SPEED IS ESSENTIAL. A DOCTOR MUST BE NOTIFIED AT ONCE.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
