Hazards and Protection.
Keep in a cool, dry location in a tightly sealed container.
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.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.
Keep away from reducing agents and combustible materials.
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
These substances will accelerate burning when involved in a fire.
May decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
Fire may produce irritating, corrosive and/or toxic gases.
Significant burns or strictures of the gastrointestinal tract are unusual following ingestion of household bleach. Vomiting is common after hypochlorite ingestions or inhalation of chlorine or chloramine gas. Hematemesis may develop after large ingestions.
Edema of the glottis as well as pulmonary edema may occur. Chloramine and chlorine gas inhalation result in coughing, choking, and dyspnea. Chemical pneumonitis, pulmonary edema and respiratory failure can occur following severe gas exposure. Mild exposures resolve with no therapy. Pneumomediastinum has been reported with chlorine gas inhalation.
Dermal irritation and hypersensitivity have been reported with chlorine active compounds. Small volumes of sodium hypochlorite injected iv have produced erythema at the site of injection.
DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician.
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used.
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
