victim to fresh air. Call emergency medical care. Apply artificial respiration
if victim is not breathing. Do not use mouth-to-mouth method 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. Administer oxygen if breathing is difficult. Remove and isolate
contaminated clothing and shoes. In case of contact with substance, immediately
flush skin or eyes with running water for at least 20 minutes. For minor skin
contact, avoid spreading material on unaffected skin. Keep victim warm and
quiet. Effects of exposure (inhalation, ingestion, or skin contact) may be
delayed. Ensure that medical personnel are aware of the material(s) involved,
and take precautions to protect themselves.
