4 Storage and Handling
Containers should only be manoeuvred with suitable lifting equipment. Care should be taken in moving cylinder to its final position where it should be held securely with suitable retaining devices.
4.1 Special Storage and Handling Precautions
Storage and handling precautions, as applicable to liquefied gas under pressure
4.2 Packing Materials
Avoid alloys with more than 2% magnesium & plastics. Steel, stainless steel & aluminium may be used.
4.3 Decomposition Products
Stable at ambient temperature. Above 500deg c. Will decompose.
4.4 Dangerous reactions with alkaline and alkaline earth metals at high temperatures.
4.5 Individual Prevention & Protective Measures
Gloves and goggles are recommended avoid contact with skin and eyes
4.6 Special Measures
Ventilate working area . No smoking. No naked lights.
4.7 Spillage or Leakage
In a closed area ventilate or wear c.a.b.a. (risk of intoxication). Allow to evaporate. Prevent from entering sewers, basements etc. Eliminate all ignition sources.
4.7.1 Neutralisation
Allow to evaporate
4.7.2 Destruction of Containers
Return to supplier
4.8 Other Recommendations
Store in ventilated area below 50deg C; away from sources of heat
5 Ignition and Explosion
None.
5.1 Flash Point
None
5.2 Auto Ignition Temperature
Non flammable product. Thermal decomposition gives toxic fumes of hydrobromic and hydrofuoric acids.
5.3 Special Fire or Explosion Hazards
Not applicable
5.4 Extinction
If spillage has occurred or if a risk exists that over pressurisation will take place with possible loss of product from the cylinder then wear self contained breathing apparatus, (positive pressure).
5.5 Special Fire Fighting Methods
Cool the containers to avoid over pressurisation. The container valves are fitted with a fusible plug designed to burst at 69deg C. To ensure that the cylinder itself does not burst.
5.6 Other Recommendations
Employers should be aware that this product is solvent abusable at high concentrations.
Vapour: no problems below 50,000 ppm. At very high concentrations irritation of eyes & mucous membranes could occur with some interface to nervous & respiratory systems, which is reversible.
Ingestion not likely as product only exists as a gas at ambient temperatures. Liquid severe frost bite will occur on contact with skin and eyes. Initially there will be pain and redness then the area will become white and painless.
