Material Safety Data Sheet
Nessler's reagent, APHA for Nitrogen (Ammonia)
Skin:
Causes redness, irritation, sensitization dermatitis. Mercury is absorbed through skin producing gastrointestinal and
kidney damage. Severe alkali burns can occur.
Ingestion:
Burns, pain, vomiting, diarhhea, metallic taste, death from electrolyte loss/imbalance, vascular collapse, renal failure;
alkali burns, perforation.
Inhalation:
Corrosive/neurotoxin/neprhotoxin.
Chronic:
May cause dermatitis and conjunctivitis. Sensitization, neuropathologic disturbances, kidney damage, mutagenic and
reproductive effects.
Section 4 - First Aid Measures
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids until
chemical is gone. Get medical aid at once. Cover burns with loose sterile non-medicated bandages.
Skin:
Get medical aid. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing
contaminated clothing and shoes. Cover burns with a dry sterile bandage (secure, not tight).
Ingestion:
Do NOT induce vomiting. Get medical aid at once. Give conscious victim large quantities of water to dilute.
Inhalation:
Give artificial respiration if necessary. Get medical aid. Keep victim warm, at rest. Move victim to fresh air. Maintain
airway, medical personnel may administer oxygen.
Notes to Physician:
Treat symptomatically and supportively.
Section 5 - Fire Fighting Measures
General Information:
Negligible fire and explosion hazard when exposed to heat or flame. Move container if possible, cool with fog or
spray. Water spray may be used to absorb corrosive vapors. Avoid breathing corrosive poisonous vapors.
