IV. HEALTH HAZARDS:
Due to the small amount of material in each tablet, the hazard associated with each package is minimal.
This information is obtained from the MSDS of the individual raw materials and other reliable sources and
may or may not be directly applicable to the small amount of the individual material or mixtures. The
tablets are to be used under supervision of a chemist or trained laboratory instructor.

CHRONIC HEALTH EFFECTS due to long term or repeated exposure:
Sodium Chloride (NaCl): Has been reported to cause elevated blood pressure and accelerated respiration rate.
Arsenazo III: Listed as a possible carcinogen. There is evidence that inorganic arsenic compounds are skin and
lung carcinogens in humans.
V. FIRST AID MEASURES
Skin: Wash hands thoroughly after contact using soap and warm water. If spilled on clothing, flush
affected areas with water, remove contaminated clothing as soon as possible and wash before
reuse.
Ingestion: Because each tablet contains a small sample size (1g or less), most of the tablets present
little hazard. Rinse out the mouth with plenty of water. If ingested, drink 1-2 glasses of water
and induce vomiting. Never give anything by mouth to an unconscious person. Seek medical
attention.
Eye Contact: Immediately flush eyes with running water for at least 15 minutes, keeping eyelids open. Obtain
medical attention if irritation persists.
Inhalation: Remove victim to a well ventilated area. If not breathing, give artificial respiration. If breathing
is difficult, give oxygen. Seek medical attention.

VII. FIRE AND EXPLOSION HAZARDS
Almost all of the Indi-Tab Kit #2 tablets, emit toxic fumes under fire conditions. See the above table for
comments on each individual type. Methylthymol Blue Complexone may explode on ignition when mixed with
finely divided materials. Contact with combustible materials may cause fire. Potassium Nitrate is a Strong
Oxidizer. Contact with other material may cause fire. Calcein Blue and Arsenazo III in fire may produce
poisonous gases.
VIII. FIRE FIGHTING MEASURES
Extinguisher: Water Spray. Carbon Dioxide, dry chemical powder or appropriate foam.
Special Equipment: Wear self-contained breathing apparatus and protective clothing to prevent contact with skin
and eyes.
IX. EXPOSURE CONTROLS ?PERSONAL PROTECTION
Respiratory: NIOSH/OSHA-approved Respirator: mechanical exhaust.
Hand Protection: Compatible Chemical-Resistant Gloves
Eye Protection: Chemical Safety Goggles
Skin Protection: Overalls; Clean body-covering over-clothing.
Hygiene Measures: Wash thoroughly after handling.
X. STORAGE AND DISPOSAL
Store in a cool, well ventilated area, away from incompatible chemicals or materials. Avoid contact with eyes,
skin, and clothing. Dispose in accordance with Federal, State and Local regulations.
