SDS

Fire/Explosion Hazard
Containers may explode when heated - Ruptured cylinders may rocket
Fire exposed containers may vent contents through pressure relief devices.
High concentraons of gas may cause asphyxiaon without warning.
May decompose explosively when heated or involved in fire.
Contact with gas may cause burns, severe injury and/ or frostbite.
Decomposion may produce toxic fumes of:, carbon monoxide (CO), carbon dioxide (CO2), hydrogen chloride, phosgene, hydrogen fluoride , other
pyrolysis products typical of burning organic material Contains low boiling substance: Closed containers may rupture due to pressure buildup
under fire condions.
SECTION 6 ACCIDENTAL RELEASE MEASURES
6.1. Personal precauons, protecve equipment and emergency procedures
See secon 8
6.2. Environmental precauons
See secon 12
6.3. Methods and material for containment and cleaning up
Minor Spills
Avoid breathing vapour and any contact with liquid or gas. Protecve equipment including respirator should be used.
DO NOT enter confined spaces were gas may have accumulated.
Increase venlaon.
Major Spills
Clear area of all unprotected personnel and move upwind.
Alert Emergency Authority and advise them of the locaon and nature of hazard.
Wear breathing apparatus and protecve gloves.
Prevent by any means available, spillage from entering drains and water-courses.
Remove leaking cylinders to a safe place.
Fit vent pipes. Release pressure under safe, controlled condions
Burn issuing gas at vent pipes.
DO NOT exert excessive pressure on valve; DO NOT aempt to operate damaged valve.
6.4. Reference to other secons
Personal Protecve Equipment advice is contained in Secon 8 of the SDS.
SECTION 7 HANDLING AND STORAGE
7.1. Precauons for safe handling
Safe handling Vented gas is more dense than air and may collect in pits, basements.
Fire and explosion
protecon
See secon 5
Other informaon
Cylinders should be stored in a purpose-built compound with good venlaon, preferably in the open.
Such compounds should be sited and built in accordance with statutory requirements.
The storage compound should be kept clear and access restricted to authorised personnel only.
Cylinders stored in the open should be protected against rust and extremes of weather.
7.2. Condions for safe storage, including any incompabilies
Suitable container
DO NOT use aluminium or galvanised containers
|Cylinder: Steel Packaging|Ensure the use of equipment rated for cylinder pressure.|Ensure the use of compable materials of
construcon.|Valve protecon cap to be in place unl cylinder is secured, connected.|Cylinder must be properly secured either in use or in
storage.|Cylinder valve must be closed when not in use or when empty.|Segregate full from empty cylinders|WARNING: Suckback into cylinder
may result in rupture. Use back-flow prevenve device in piping.
Storage incompability
Avoid reacon with oxidising agents
Avoid magnesium, aluminium and their alloys, brass and steel.
Haloalkanes:
are highly reacve:some of the more lightly substuted lower members are highly flammable; the more highly substuted may be used as fire
suppressants, not always with the ancipated results.
may react with the lighter divalent metals to produce more reacve compounds analogous to Grignard reagents.
may produce explosive compounds following prolonged contact with metallic or other azides
may react on contact with potassium or its alloys - although apparently stable on contact with a wide rage of halocarbons, reacon products
may be shock-sensive and may explode with great violence on light impact; severity generally increases with the degree of halocarbon
substuon and potassium-sodium alloys give extremely sensive mixtures .
BRETHERICK L.: Handbook of Reacve Chemical Hazards
react with metal halides and acve metals, eg. sodium (Na), potassium (K), lithium (Li),calcium (Ca), zinc (Zn), powdered aluminium (Al) and
aluminium alloys, magnesium (Mg) and magnesium alloys.
