Chlorates, incompatibilities with

SAFETY PROFILE A poison. For fire and explosion hazards, see CHLORATES. Incompatible with Al, As, C, charcoal, Cu, Mn02, metal sulfides, S4N4, organic matter, P, S. See also BARIUM COMPOUNDS (soluble). 

AMMONIUM SULPHATE (7783-20-2) H8N2O4S Noncombustible solid. Aqueous solution is a strong acid. Violent reaction with fused potassium chlorate potassium nitrite. Reacts with caustics, forming ammonia. Hot material reacts with nitrates, nitrites, chlorates. Incompatible with strong oxidizers sulfuric acid aliphatic amines alkanolamines, amides, organic anhydrides isocyanates, vinyl acetate aUcylene oxides epichlorohydrin. Mixture with sodium hypochlorite forms nitrogen trichloride, an unstable explosive material. Attacks metals in the presence of moisture. 

METHYL SULFOCYANATE (556-64-9) CjHjNS May be flammable. Violent reactions have occurred when mixed with chlorates, nitrates, nitric acid, peroxides and hydroperoxides perchlorates, potassium chlorate, and sodium chlorate. Incompatible with acid fiimes and/or chlorosulfonic acid, oleum, sulfuric acid, and other mineral acids, releasing deadly toxic hydrogen cyanide gas, and toxic oxides of nitrogen and sulfur afad nitriles. On small fires, use dry chemical powder (such as Purple-K-Powder), water spray, or COj extinguishers. 

COBALT (7440-48-4) An extreme fire hazard. Pyrophoric particles or dust can self-ignite in air. Violent reaction with acetylene, ammonium nitrate, bromine pentafluoride, bromine trifluoride, cumene hydroperoxide, hydrogen peroxide (90%), nitryl fluoride, organic peroxides forms explosive mixture with potassium chlorate. Incompatible with sodium borohydride. Capable of promoting the decomposition of many organic materials. 

Barium chlorate creates mixtures which are strongly explosive with sulphur or phosphorus. It is incompatible with ammonium salts. Besides, in the presence of sulphuric acid, and like any other chlorate, it forms chlorine dioxide, which detonates at ambient temperature. 

OSHA PEL TWA 0.01 mg(As)/m3 ACGIH TLV TLV 0.01 mg/m Confirmed Human Carcinogen BEI 35 n (As)/L inorganic arsenic and methylated metabolites in urine NIOSH REL CL 2 ng(As)/mVl5M SAFETY PROFILE Confirmed human carcinogen. See also ARSENIC COMPOUNDS and SULFIDES. Flammable in the form of dust when exposed to heat or flame. Explosive when intimately mixed with powerful oxidizers, such as CI2, KNO3, or chlorates. Will react with water and steam to produce toxic and flammable vapors. Incompatible with water, steam, and strong oxidizers. 

SAFETY PROFILE A poison. Flammable by spontaneous chemical reaction, air, moisture, or acid fumes may cause it to ignite. For explosion and disaster hazards, see SULFIDES. To fight fire, use CO2, dry chemical. Reacts violently with phosphorus(V) oxide. Mixtures with lead dioxide, potassium chlorate, or potassium nitrite explode when heated. Incompatible with CI2O, Ca(N03)2, Sr(N03)2, Ca(C103)2, Sr(C103)2, (C103)2. See also BARIUM COMPOUNDS (soluble) and SULFIDES. 

DFG MAK 1.5mg/m3 DOT CLASSIFICATION 4.2 Label Spontaneously Combustible SAFETY PROFILE Moderately toxic by intravenous route. Experimental reproductive effects. It can cause a dust irritation, particularly to the eyes and mucous membranes. See also CARBON BLACK, SOOT. Combustible when exposed to heat. Dust is explosive when exposed to heat or flame or oxides, peroxides, oxosalts, halogens, interhalogens, O2, (NH4NO3 + heat), (NH4CIO4 240°), bromates, Ca(OCl)2, chlorates, (CI2 + Cr(OCl)2), CIO, iodates, IO5, Pb(N03)2, HgNOs, HNO3, (oils + air), (K + air), Na2S, Zn(N03)2. Incompatible with air, metals, oxidants, unsaturated oils. 

Rb2C2, Na, Na2C2, SnO, diaminolithiumacetylene carbide. Will react with water or steam to produce toxic and corrosive fumes. Incompatible with halogens or interhalogens, lithium nitrate, metal acetyUdes, metal oxides, metals, polymeric tubing, potassium chlorate, sodium hydride. 

Incompatible with sulfuric acid, isocyanates, chlorates, nitrates, nitrites, with loss of toxic ammonia, hydrogen sulfide, and sulfur trioxide gases. In temperatures above 302°F/150°C, releases toxic flunes of ammonia, hydrogen sulfide, and oxides of nitrogen and sulfiir. 

BARIUM SULFIDE (21109-95-5) BaS Flammable solid. Oxidizes in dry air. Contact with acid, acid fumes, moisture, steam, or moist air causes decomposition with the formation of toxic and flammable hydrogen sulfide gas. Evolved gas can form explosive mixtures with air and may cause spontaneous ignition or explosion. Violent reaction with strong oxidizers, calcium chlorate calcium nitrate chlorine dioxide phosphorus(V) oxide strontium chlorate strontium nitrate. Incompatible with lead dioxide, potassium chlorate, potassium nitrite may explode at elevated temperatures. On small fires, use smothering quantities of dry chemical powder, dry clay, dry groimd limestone (CaCOj), dry soda ash,dry sand or approved Class D extinguishers, do not use water, foam, or hydrous agents.
