INHALATIONSGEFAHREN
Eine gesundheitsschädliche Konzentration des Gases in der Luft wird beim Entweichen aus dem Behälter sehr schnell erreicht.
WIRKUNGEN BEI KURZZEITEXPOSITION
WIRKUNGEN BEI KURZZEITEXPOSITION: Die Substanz reizt die Atemwege. Inhalation dieses Gases kann zu Lungenödem führen (s.Anm.). Inhalation hoher Konzentrationen kann zu Methämoglobinbildung führen. Die Flüssigkeit kann Erfrierungen hervorrufen. ärztliche Beobachtung notwendig. Die Auswirkungen treten u.U. verzögert ein.
WIRKUNGEN NACH WIEDERHOLTER ODER LANGZEITEXPOSITION
Möglich sind Auswirkungen auf das Blut mit nachfolgender Methämoglobinbildung. Das Gas kann Fluorose verursachen (s. Anm.).
LECKAGE

Chemische Eigenschaften
Perchloryl fluoride is a colorless gas. Characteristic sweet odor. Shipped as a liquefied compressed gas.
Verwenden
perchloryl fluoride's uses are as an effective fluorinating agent, as an oxidant in rocket fuels, and as a gaseous dielectric for transformers.
Allgemeine Beschreibung
Perchloryl fluoride is a colorless, non corrosive gas with a characteristic sweet odor. Contact with the material may cause irritation to skin, eyes, and mucous membranes. Perchloryl fluoride is very toxic by inhalation and skin absorption. Under prolonged exposure to fire or intense heat the containers may violently rupture and rocket.
Air & Water Reaktionen
Slightly soluble in water.
Reaktivität anzeigen
Perchloryl fluoride is a propellant; a powerful oxidant. Perchloryl fluoride ignites upon contact with alcohols, amines, ammonia, beryllium alkyls, boranes, dicyanogen, hydrazines, hydrocarbons, hydrogen, nitroalkanes, powdered metals, silanes, or thiols [Bretherick 1979. p.174].
Health Hazard
TOXIC; may be fatal if inhaled or absorbed through skin. Fire will produce irritating, corrosive and/or toxic gases. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Runoff from fire control may cause pollution.
Brandgefahr
Substance does not burn but will support combustion. Vapors from liquefied gas are initially heavier than air and spread along ground. These are strong oxidizers and will react vigorously or explosively with many materials including fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react violently with air, moist air and/or water. Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket.
Sicherheitsprofil
A poison gas which forms methemoglobin in the body and destroys red cells causing anemia, anorexia, and cyanosis. Recovery is said to be rapid, leaving no permanent physiological damage. Can be absorbed through the skin. Its odor can be detected as low as 10 ppm although this cannot be relied upon as an indication of toxic concentration in air. While nonflammable, it supports combustion. It is a powerful oxidzer. Moderately explosive. Potentially explosive reactions with combustible gases or vapors. benzene + aluminum trichloride, benzocyclobutene + butyllithium + potassium tert-butoxide, calcium acetylide, potassium cyanide, potassium thiocyanate, sodium iochde, charcoal, ethyl-4-fluorobenzoylacetate, hydrocarbons, hydrogen sulfide, nitrogen oxide, sulfur dichloride, vinylidene chloride, 3a-hydroxy-5p-androstane-1 1,17-di0ne-l 7hydrazone, lithiated compounds, 2lithio (dimet hy laminomethyl)f erroxene, methyl-2-bromo-5,5-ethylene dioxy(2,2,1)bicycloheptane-7-carboxylate, aliphatic heterocyclic amines, sodium methoxide + methanol, vinylidene chloride. Reacts to form explosive products with nitrogenous bases (e.g., isopropylamine, isobutylamine, aniline, phenyl hydrazine, 1,2-diphenyl hydrazine), sawdust, lampblack. Violent reaction with finely dwided organic materials. A fluorinating agent in chemical synthesis, and an oxidant in rocket fuel. When heated to decomposition it emits toxic fumes of Fand Cl-.

mögliche Exposition
Perchloryl fluoride has been used as a liquid oxidant in rocket propellant combinations; as an insulating gas in high voltage electrical systems; as a fluorinating agent in organic synthesis.
Versand/Shipping
UN3083 Perchloryl fluoride, Hazard Class: 2.3; Labels: 2.3-Poisonous gas, 5.1-Oxidizer, Inhalation Hazard Zone B. UN3157 Liquefied gas, oxidizing, n.o.s., Hazard Class: 2.2; Labels: 2.2-Non-flammable compressed gas, 5.1-Oxidizer, Technical Name Required. Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner.
Inkompatibilitäten
A strong oxidizing gas. Violent reaction with benzene, calcium hydride; combustibles, olefins, strong bases; sulfur, sulfuric acid; amines, reducing agents; alcohols. Contact with carbonaceous materials (such as charcoal) or finely divided metals (such as powdered magnesium and aluminum, zinc) are a fire and explosion hazard. Attacks some plastics, rubber, and coatings
Waste disposal
Return refillable compressed gas cylinders to supplier. Incineration together with flammable solvent in furnace equipped with afterburner and scrubber.
