Following ingestion
Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 140 [Oxidizers]: Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Hypochlorite and Related Compounds
SECTION 5: Fire-fighting measures
5.1 Suitable extinguishing media
If material involved in fire: Extinguish using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Chlorinated lime, liquid
5.2 Specific hazards arising from the chemical
Excerpt from ERG Guide 140 [Oxidizers]: These substances will accelerate burning when involved in a fire. Some 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. (ERG, 2016)

SECTION 10: Stability and reactivity
10.1 Reactivity
Decomposes rapidly above 175°C . Decomposes rapidly on contact with acids. This produces chlorine and oxygen. This generates fire and explosion hazard. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. The solution in water is a medium strong base. Reacts violently with ammonia, amines, nitrogen compounds and many other substances. This generates explosion hazard. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Attacks plastics.
10.2 Chemical stability
All hypochlorite soln are unstable, esp if acidified; slowly decomp on contact with air hypochlorite soln
10.3 Possibility of hazardous reactions
Contact with combustible materials will increase fire hazard. May undergo accelerated decomposition with release of heat above 350 deg F (177 deg C). /Calcium hypochlorite, dry, or calcium hypochlorite, mixtures, dry/CALCIUM HYPOCHLORITE is a powerful oxidizing agent, particularly in the presence of water or as it decomposes when heated to release oxygen and chlorine gases. May react vigorously with carbon; reacts potentially explosively with finely divided carbon. Reacts with acetylene to form explosive chloroacetylenes. Reactions with organic matter, oil, hydrocarbons; alcohols may lead to explosions. Reactions with nitromethane, methanol, ethanol (and other alcohols) can become violent after a delay. Reacts with possible ignition and/or explosion with organic sulfur compounds and with sulfides. Decomposes evolving oxygen, a change that can be catalyzed by rust on metal containers. Forms highly explosive NCl3 on contact with urea or ammonia. Evolves highly toxic gaseous chlorine gas when heated or on contact with acids [Sax, 9th ed., 1996, p. 1905]. A mixture with damp sulfur reacted violently, and molten sulfur was ejected [Chem Eng. News, 1965, 46(29), 6]. The combination of calcium hypochlorite, sodium hydrogen sulfate, starch, and sodium carbonate, when compressed, caused the materials to incandescence, followed by explosion, [Ind. Eng. Chem., 1937, 15, 282].
10.4 Conditions to avoid
no data available
10.5 Incompatible materials
Reacts with water and with acids releasing chlorine. Forms explosive compounds with ammonia and amines. Strong oxidizer. Other incompatible materials include organics, nitrogen containing compounds, dry chemical fire extinguishers containing mono-ammonium phosphate, combustible or flammable materials. Calcium hypochlorite, dry or calcium hypochlorite, mixtures, dry
10.6 Hazardous decomposition products
The 70% grade may decomp violently if exposed to heat or direct sunlight. Gives off chlorine and chlorine monoxide above 350 deg F (poisonous gases).
