All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.
Promazine HCl is maximally stable at pH 6.5 Promazine HCl oxidizes upon prolonged exposure to air and acquires blue or pink color.
Strong oxidizing agents.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
Phenothiazines may interfere with the body's ability to thermoregulate, and cause elevated body temperature or reduced body temperature. Abnormally low blood pressure and elevated blood pressure have both been reported; abnormally low blood pressure is the more common serious effect. CNS depression, coma, agitation, extrapyramidal signs, and seizures may occur with overdose. Neuroleptic malignant syndrome has rarely occurred with therapeutic use and overdose. Most phenothiazines are rated pregnancy category C and should be used only when potential therapeutic benefit outweighs potential effects on the fetus.
Gastrointestinal abnormalities, especially constipation with possible obstruction, may occur with phenothiazine overdose.
Respiratory depression, pulmonary edema, and a loss of the gag reflex with possible aspiration may occur with phenothiazine overdose.
Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
