Oxygen release in case of heat; combustible in case of organic matter, reducing agent, metal powder

Slightly soluble in cold water; soluble in hot water.

Oxidizing Agents, Strong

Explosive

THALLIUM CHLORATE is an oxidizing agent. May initiate combustion when exposed to organic materials. May liberate explosive chlorine dioxide gas when heated in the presence of strong acid. May liberate chlorine dioxide and carbon dioxide if heated in contact with moist dibasic carboxylic acids. Mixtures with ammonium salts, powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979 p. 806]. A combination with finely divided aluminum may explode by heat, percussion, or friction [Mellor 2:310 1946-47].

Explosive in case of organic matter, metal powder and reducing agent

Excerpt from ERG Guide 141 [Oxidizers - Toxic]: These substances will accelerate burning when involved in a fire. May explode from heat or contamination. Some may burn rapidly. 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)

Excerpt from ERG Guide 141 [Oxidizers - Toxic]: SMALL FIRE: Use water. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control. LARGE FIRE: Flood fire area with water from a distance. Do not move cargo or vehicle if cargo has been exposed to heat. Move containers from fire area if you can do it without risk. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2016)

Excerpt from ERG Guide 141 [Oxidizers - Toxic]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 141 [Oxidizers - Toxic]: Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area. LARGE SPILL: Dike far ahead of spill for later disposal. (ERG, 2016)

Excerpt from ERG Guide 141 [Oxidizers - Toxic]: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing will only provide limited protection. (ERG, 2016)

Excerpt from ERG Guide 141 [Oxidizers - Toxic]: Toxic by ingestion. Inhalation of dust is toxic. Fire may produce irritating, corrosive and/or toxic gases. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution. (ERG, 2016)

Excerpt from ERG Guide 141 [Oxidizers - Toxic]: Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. Contaminated clothing may be a fire risk when dry. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Keep victim calm and warm. (ERG, 2016)
