Hazards and Protection.
Commercially available hydroflumethiazide tablets should be stored at room temperature (approximately 25C).
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.

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.
Unstable in alkaline solution.
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.
in overdose lethargy and coma have been reported in children ingesting thiazide diuretics. Altered mental status, headache, hypertonia, muscle weakness, and seizures may develop secondary to diuretic-induced electrolyte abnormalities. Ototoxicity occurs rarely and is usually reversible.
Noncardiogenic pulmonary edema after hydrochlorothiazide ingestion has been reported and is believed to be an idiosyncratic reaction.
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.
