Bromchlordifluormethan Chemische Eigenschaften,Einsatz,Produktion Methoden
ERSCHEINUNGSBILD
KOMPRIMIERTES FLüSSIGGAS MIT CHARAKTERISTISCHEM GERUCH.
PHYSIKALISCHE GEFAHREN
Das Gas ist schwerer als Luft. Es kann sich in tiefer gelegenen Bereichen sammeln und den Luftsauerstoff verdr?ngen.
CHEMISCHE GEFAHREN
Zersetzung bei Kontakt mit offenen Flammen oder sehr hei?en Oberfl?chen unter Bildung giftiger Gase mit Phosgen, Fluorwasserstoff, Chlorwasserstoff und Bromwasserstoff.
ARBEITSPLATZGRENZWERTE
TLV nicht festgelegt (ACGIH 2005).
MAK nicht festgelegt (DFG 2005).
AUFNAHMEWEGE
Aufnahme in den K?rper durch Inhalation.
INHALATIONSGEFAHREN
Beim Entweichen aus dem Beh?lter verdampft die Flüssigkeit sehr schnell, wobei die Luft verdr?ngt wird. Hohe Erstickungsgefahr in geschlossenen R?umen.
WIRKUNGEN BEI KURZZEITEXPOSITION
WIRKUNGEN BEI KURZZEITEXPOSITION: Schnelle Verdampfung kann zu Erfrierungen führen. M?glich sind Auswirkungen auf das Herzkreislaufsystem mit nachfolgenden Herzfunktionsst?rungen.
LECKAGE
Belüftung. NICHT in die Umwelt gelangen lassen.
R-S?tze Betriebsanweisung:
R36/37/38:Reizt die Augen, die Atmungsorgane und die Haut.
S-S?tze Betriebsanweisung:
S23:Gas/Rauch/Dampf/Aerosol nicht einatmen(geeignete Bezeichnung(en) vom Hersteller anzugeben).
S36/37/39:Bei der Arbeit geeignete Schutzkleidung,Schutzhandschuhe und Schutzbrille/Gesichtsschutz tragen.
Chemische Eigenschaften
Chlorodifluorobromomethane is a colorless
gas or liquid under pressure.
Definition
ChEBI: A one-carbon compound that is methane in which the hydrogens have been replaced by two fluorines, a bromine, and a chlorine. Widely used in 'vapourising liquid'-type fire extinguishers, its use is now generally banned under the Montreal Protocol (ozone-dep
eting substances), although it is still used in certain applications (e.g. aviation).
Allgemeine Beschreibung
BROMOCHLORODIFLUOROMETHANE is a colorless, nonflammable gas. BROMOCHLORODIFLUOROMETHANE is mildly toxic by inhalation. BROMOCHLORODIFLUOROMETHANE can asphyxiate by the displacement of air. Exposure of the container to prolonged heat or fire may cause BROMOCHLORODIFLUOROMETHANE to rupture violently and rocket. BROMOCHLORODIFLUOROMETHANE is used as a refrigerant gas.
Reaktivit?t anzeigen
BROMOCHLORODIFLUOROMETHANE is chemically inert in many situations, but can react violently with strong reducing agents such as the very active metals and the active metals. Can react with strong oxidizing agents or weaker oxidizing agents under extremes of temperature.
Health Hazard
Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.
Brandgefahr
Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.
Sicherheitsprofil
Mutation data reported.
An asphyxiant. See also ARGON for
description of inert gas asphyxiants. When
heated to decomposition it emits very toxic
fumes of Br-, Cl-, and F-
m?gliche Exposition
Used as a refrigerant and fire extinguishing agent.
Versand/Shipping
UN1974 Chlorodifluorobromomethane or
Refrigerant gas R-12B1, Hazard Class: 2.2; Labels: 2.2-
Nonflammable compressed gas. 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.
Inkompatibilit?ten
The liquefied gas poured into water may
be violently explosive. This is due to the phase transition
from superheated liquid to vapor. Chlorodifluorobromomethane is generally chemically inert; however, it can
react violently with strong reducing agents such as hydrides
and highly active metals. It will react with strong oxidizers
(chlorates, nitrates, peroxides, permanganates, perchlorates,
chlorine, bromine, fluorine, etc.); contact may cause fires
or explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, epoxides strong oxidizing
agents. It can also react with weak oxidizers under extreme
temperatures.
Waste disposal
Return refillable compressed
gas cylinders to supplier.
