Ferric Chloride Solution: Etchant for copper-plated PC Boards

Ferric Chloride CAS #7705-08-0
Green-black solution in water with a mild acid-like odor.
May cause eye and skin burns. May be harmful if swallowed. Ingestion
may cause rapid heartbeat, low blood pressure, shock, and possible coma.
May cause kidney and liver damage. Inhalation of vapor may cause severe
respiratory tract irritation. Substance has caused adverse reproductive
effects in animals.
Target Organs: Kidneys, liver, cardiovascular system.
Adverse Health Effects
     If in Eyes: May cause eye burns. Contact produces irritation, tearing,
     and burning pain.
     If on Skin: May be absorbed through the skin. May cause severe
     irritation and possible burns.
     If Swallowed: May cause irritation of the digestive tract. May cause
     liver and kidney damage. Causes severe pain, nausea, vomiting,
     diarrhea, and shock. May cause severe irritation of the mouth and
     throat. May cause low blood pressure, rapid heartbeat, skin
     discoloration, and possible coma.
     If Inhaled:  Vapor may cause severe respiratory tract irritation.
     Prolonged or repeated exposure may cause adverse reproductive effects.
     Repeated exposure may increase an increased body load of iron.
FIRST AID MEASURES:
     Eyes: Immediately flush eyes with plenty of water for at least 15
     minutes, occasionally lifting the upper and lower lids. Get medical
     aid immediately. Do NOT allow victim to rub or keep eyes closed.
     Skin: Immediately 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.
     Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk
     or water. Get medical aid immediately.
     Inhalation: Remove from exposure to fresh air immediately. If not breathing,
     give artificial respiration. If breathing is difficult, give oxygen.
     Get medical aid.
     Notes to Physician:
          Treat symptomatically and supportively.
          The use of an iron chelator should be determined only by qualified
          medical personnel.
     Handling:
          Wash thoroughly after handling.
