SECTION 3: Composition/information on ingredients
Substance
- Chemical name: Phenazopyridine hydrochloride
- Common names and synonyms: Phenazopyridine hydrochloride
- CAS number: 136-40-3
- EC number: 205-243-8
- Concentration: 100%
SECTION 4: First aid measures
Description of necessary first-aid measures
Move the victim into fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration and consult a doctor immediately. Do not use mouth to mouth resuscitation if the victim ingested or inhaled the chemical.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
SYMPTOMS: Symptoms of exposure to this compound via ingestion may include headache, rash, occasional gastrointestinal disturbances, orange to red color in the urine, hemolytic anemia, renal and hepatic toxicity, and staining of contact lenses. It may cause methemoglobinemia. It may cause gastrointestinal upset. Overdose may cause oxidative Heinz body hemolytic anemia, presence of "bite cells", hemolysis, renal and hepatic impairment and occasional failure, due to hypersensitivity. Overdose may also result in hepatic enlargement, jaundice and hypersensitivity hepatitis. ACUTE/CHRONIC HAZARDS: There is limited evidence that this compound causes cancer in humans. When heated to decomposition it emits very toxic fumes of nitrogen oxides and hydrogen chloride gas. (NTP, 1992)
Indication of immediate medical attention and special treatment needed, if necessary
In acute overdosage of phenazopyridine hydrochloride, the stomach should be emptied immediately by inducing emesis or by gastric lavage. If the patient is comatose, having seizures, or lacks the gag reflex, gastric lavage may be performed if an endotracheal tube with cuff inflated is in place to prevent aspiration of gastric contents. Supportive and sympotmatic treatment should be initiated. IV administration of methylene blue 1-2 mg/kg or oral administration of ascorbic acid 100-200 mg should cause prompt reduction of methemoglobinemia and disappearance of cyanosis. Exchange transfusions have been used successfully in acute phenazopyridine overdosage in infants. Peritoneal dialysis may be useful for managing fluid and electrolyte disturbances in phenazopyridine-induced acute renal failure. Phenazopyridine hydrochloride

Appropriate engineering controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures, such as personal protective equipment (PPE)
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Possibility of hazardous reactions
PHENAZOPYRIDINE HYDROCHLORIDE is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
Conditions to avoid

Bioaccumulative potential
An estimated BCF of 10 was calculated for phenazopyridine(SRC), using an estimated log Kow of 2.77(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for phenazopyridine can be estimated to be 870(SRC). According to a classification scheme(2), this estimated Koc value suggests that phenazopyridine is expected to have low mobility in soil.
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
