4 Fire fighting measuresFlammability of the productProducts of combustionExplosion hazards in thepresence of varioussubstancesFire-fighting media andinstructionsPromptly isolate the scene by removing all persons from the vicinity of the incident ifthere is a fire. No action shall be taken involving any personal risk or without suitabletraining. Contact supplier immediately for specialist advice. Move containers from firearea if this can be done without risk. Use water spray to keep fire-exposed gas under pressure. In a fire or if heated, a pressure increase will occur andthe container may burst or protectiveequipment for fire-fightersFire-fighters should wear appropriate protective equipment and self-contained breathingapparatus (SCBA) with a full face-piece operated in positive pressure mode.:::::EVACUATE ALL PERSONNEL FROM AFFECTED appropriate protective equipment.

5 If leak is in user's equipment, be certain to purgepiping with an inert gas prior to attempting repairs. If leak is on cylinder or cylinder valve,contact the closest Air Liquide 6. Accidental release measuresPersonal precautions:Date of issue:12/31/2007 Page: 2/7 HELIUMC ontact your local Air Liquide Gas supplier for precautions:In case of a leak, clear the affected area, protect people, eliminate sources of ignitionand respond with trained leaking incidentally from the cylinder or its valve, contact your supplier. Use non-sparking tools and equipment during the for cleaning up:Protect cylinders from physical damage. Store in cool, dry, well-ventilated area of noncombustible construction away from heavy traffic areas and emergency exits. Do notallow the temperature where cylinders are stored to exceed 52 C/125 F.

6 Cylinders mustbe stored upright and firmly secured to prevent falling or being knocked over. Full andempty cylinders should be segregated. Prevent full cylinders being stored for excessiveperiods of time. Post "No Smoking or Open Flames" signs in the storage or use should be no source of ignition in the storage or use protection caps must remain in place unless cylinder is secured with valve outletpiped to usage point. Do not drag, slide or roll cylinders. Use a suitable hand truck forcylinder movement. Use a pressure regulator when connecting cylinder to lowerpressure piping or systems. Do not heat cylinder by any means to increase the dischargerate of product from the cylinder. Use a check valve or trap in the discharge line toprevent hazardous back flow to the cylinder. Do not tamper with (valve) Safety valve after each use and when 7.

7 Handling and storageHandlingStorage::Use only in well-ventilated 8. Exposure controls/personal protectionEngineering controlsMaintain oxygen levels above in the workplace. Use supplied air respiratoryprotection if oxygen levels are below (air purifying respirators will not function) orduring emergency response to a release of this gas. During an emergency situation,before entering the area, check for oxygen-deficient atmospheres. If respiratoryprotection is required, follow the requirements of the Federal OSHA RespiratoryProtection Standard (29 CFR ), or equivalent State glasses with side body protection appropriate for task. Cotton clothing is recommended for use toprevent static electric build-up. Pressurized product may require use of fire protectionEyesSkin/BodyRespiratory::::Pe rsonal protection in caseof a major leak:Wear leather gloves when handling cylinders of this gas.

8 Otherwise, wear gloveprotection appropriate to the specific operation for which this gas is : Safety glasses with side shields, goggles or face shield. Impervious gloves. Protectiveclothing. Metal cap, Safety shoes. Wear MSHA/NIOSH-approved self-containedbreathing apparatus or equivalent and full protective applications of this product may require additionnal or other specific protective clothings.
