Information on toxicological effects
Version: 1.0, Date of issue: 2016-12-23, p. 5 of 8
Safety Data Sheet
Casweld Flux AL
Acute toxicity
Lithium Chloride is an antidepressant/antipsychotic and may affect behavior/Central Nervous System (drowsiness,
mental confusion, somnolence, muscle weakness, contraction, spasticity, tremors) if ingested in high doses. It may
also affect brain (degenerative changes), metabolism (anorexia), vision (blurred vision), blood, urinary system,
cardiovascular system, and liver. Zinc Chloride affects behavior/ Central Nervous System (central nervous system
depression), the urinary system (kidney damage – hematuria, oliguria, and renal failure), cardiovascular system,
respiration (dyspnea), metabolism, pancreas (elevated amylase, and glucose levels), liver enzymes, and blood
(changes in white and red blood cell count, changes in serum composition). Sodium Fluoride may affect
behavior/Central Nervous System/Nervous System (headache, nervousness, dizziness, seizures, convulsions,
tremors, muscle weakness, somnolence, respiration (respiratory depression, dyspnea), cardiovascular system
(weak pulse, hypotension, dysrhythmias, cardiac arrest), liver, urinary system (polyuria, polydipsia), brain,
metabolism (loss of appetite, hypcalcemia, hyperkalemia, and hypo magnesia), teeth, bones, and blood (changes in
red and white blood cell counts, interference in blood coagulation).
Eye Contact: may cause severe irritation with possible eye burns and irreversible eye injury. Also it may cause
corneal ulceration, chemical conjunctivitis, and opacification, and glaucoma and severe iritis.
Skin Contact: Causes skin irritation with possible burns, especially if skin is wet or moist. Also it may be absorbed
by the skin. Inhalation: may cause severe respiratory tract irritation, headache, cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood), delayed lung edema, bronchial asthma. Inhalation of fumes may cause
mental fume fever. It is characterized by flu-like symptoms (fever, chills, cough, muscle pain, weakness), chest
pain. Also may cause irritation and chemical burns of the respiratory tract with coughing, breathing difficulty and
possibly nasal septum perforation and coma. Ingestion: Harmful if swallowed. Also it may cause severe digestive
tract irritation with thirst, salivation, nausea, vomiting, hypermotility, diarrhea, abdominal pain, possible burns
(corrosion and permanent tissue destruction) of the esophagus and digestive tract and perforation of the stomach
and possible death.

Summary of evaluation of the CMR properties
Chronic Effects: Lithium Chloride may affect behaviour/ Central Nervous System and cardiovascular system, and
have
similar affects to acute ingestion. Zinc Chloride may cause defatting and dermatitis with repeated or prolonged skin
contact.
Sodium Fluoride may cause fluorosis. Effects of Fluorosis may include joint pain, weakness, limited joint mobility,
brittle bones,
ossification on x-ray, thickening of long bone cortices, calcification of ligaments, osteomalacia, osteosclerosis
(skeletal (bone
and teeth) abnormalities) and mottled tooth enamel. Other symptoms may include anemia, nausea, vomiting,
diarrhea or
constipation, kidney damage and weight loss/anorexia. Chronic inhalation may cause bronchitis to develop with
cough, phlegm,
and/or shortness of breath, and liver complications (hepatic enzymes increased, jaundice). Prolonged or repeated
exposure to
sodium fluoride can cause damage to the lungs.
