contaminated area and allowed to breath fresh air. The short time taken for this
operation is essential. All unconscious persons must be carried outside from the
contaminated area and given cardiopulmonary resuscitation (CPR) with a supplementary
of oxygen. Others should be treated according to their symptoms and needs. Get
medical attention immediately.
: In case of contact, immediately flush skin with plenty of water. Get medical attention if

any contact lenses. In case of contact, immediately flush eyes with plenty of water for at
least 20 minutes. Get medical attention immediately.

: Effects of contact or inhalation may be delayed. Provide general supportive measures.
Notes to physician
Oxygen may be beneficial. The medical doctor must be warned that the person inhaled
a very toxic gas.

Section 6. Accidental release measures
: EVACUATE ALL PERSONNEL FROM AFFECTED AREA.
Personal precautions
Use appropriate protective equipment. If leak is in user's equipment, be certain to purge
piping with an inert gas prior to attempting repairs. If leak is on container or container
valve, contact the closest Air Liquide Canada location.
: Ensure emergency procedures to deal with accidental gas releases are in place to avoid

caused environmental pollution (sewers, waterways, soil or air).
Immediately contact emergency personnel. Stop leak if without risk. Note: see section 1
Methods for cleaning up :
for emergency contact information and section 13 for waste disposal.
Section 7. Handling and storage
: Valve protection caps must remain in place unless cylinder is secured with valve outlet
Handling
piped to usage point. Do not drag, slide or roll cylinders. Use a suitable hand truck for
cylinder movement. Use a pressure regulator when connecting cylinder to lower
pressure piping or systems. Do not heat cylinder by any means to increase the discharge
rate of product from the cylinder. Use a check valve or trap in the discharge line to
prevent hazardous back flow to the cylinder. Do not tamper with (valve) safety device.
Close valve after each use and when empty.
: Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of non
Storage
combustible construction away from heavily trafficked areas and emergency exits. Do
not allow the temperature where cylinders are stored to exceed 52癈/125癋. Cylinders
must be stored upright and firmly secured to prevent falling or being knocked over. Full
and empty cylinders should be segregated. Use a "first in - first out" inventory system to
prevent full cylinders being stored for excessive periods of time. Post "No Smoking or
Open Flames" signs in the storage or use area. There should be no source of ignition in
the storage or use area.
