4.	FIRST AID MEASURES

Description of first aid measures

General advice	Show this safety data sheet to the doctor in attendance.

Inhalation	Remove to fresh air and keep comfortable for breathing. If breathing is difficult, give oxygen. If breathing has stopped, give artificial respiration. Get medical attention immediately.

Skin contact	None under normal use. Get medical attention if symptoms occur.

Eye contact	None under normal use. Get medical attention if symptoms occur.

Ingestion	Not an expected route of exposure.

Self-protection of the first aider	RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS.

Most important symptoms and effects, both acute and delayed
Symptoms	Simple asphyxiant. May cause suffocation by displacing the oxygen in the air. Exposure to

oxygen-deficient atmosphere (<19.5%) may cause dizziness, drowsiness, nausea, vomiting, excess salivation, diminished mental alertness, loss of consciousness and death. Exposure to atmospheres containing 8-10% or less oxygen will bring about unconsciousness without warning and so quickly that the individuals cannot help or protect themselves. Lack of sufficient oxygen may cause serious injury or death.

Indication of any immediate medical attention and special treatment needed

Note to physicians	Treat symptomatically.

5.	FIRE-FIGHTING MEASURES

Suitable extinguishing media
Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.

Specific extinguishing methods
Continue to cool fire exposed cylinders until flames are extinguished. Damaged cylinders should be handled only by specialists.

Specific hazards arising from the chemical
Non-flammable gas. Cylinders may rupture under extreme heat.

Protective equipment and precautions for firefighters
As in any fire, wear self-contained breathing apparatus pressure-demand, NIOSH (approved or equivalent) and full protective gear.

6.	ACCIDENTAL RELEASE MEASURES

Personal precautions, protective equipment and emergency procedures 	

Personal precautions	Evacuate personnel to safe areas. Ensure adequate ventilation, especially in confined areas.
Monitor oxygen level. Wear self-contained breathing apparatus when entering area unless atmosphere is proved to be safe.

Environmental  precautions 	

Environmental precautions	Prevent spreading of vapors through sewers, ventilation systems and confined areas.

Methods and material for containment and cleaning up 	

Methods for containment	Stop the flow of gas or remove cylinder to outdoor location if this can be done without risk.  If leak is
in container or container valve, contact the appropriate emergency telephone number in Section 1 

Methods for cleaning up	Return cylinder to supplier

7.	HANDLING AND STORAGE

Precautions for safe handling

Advice on safe handling

Protect cylinders from physical damage; do not drag, roll, slide or drop. When moving cylinders,
even for short distance, use a cart designed to transport cylinders. Never attempt to lift a cylinder by  its valve protection cap. Never insert an object (e.g. wrench, screwdriver, pry bar,etc.) into valve cap openings. Doing so may damage valve, causing leak to occur. Use an adjustable strap wrench to remove over-tight or rusted caps. Use only with adequate ventilation. Use equipment rated for 
cylinder pressure. Use a backflow preventive device in piping. Close valve after each use and when                                  empty. If user experiences any difficulty operating cylinder valve discontinue use and contact supplier. Ensure the complete gas system has been checked for leaks before use.

Never put cylinders into trunks of cars or unventilated areas of passenger vehicles. Never attempt to refill a compressed gas cylinder without the owner's written consent. Never strike an arc on a compressed gas cylinder or make a cylinder a part of an electrical circuit.

Only experienced and properly instructed persons should handle gases under pressure. Always store and handle compressed gas cylinders in accordance with Compressed Gas Association, pamphlet CGA-P1, Safe Handling of Compressed Gases in Containers.

For additional recommendations consult Compressed Gas Association's (CGA) Safety Bulletin SB-2, Oxygen-Deficient Atmospheres.

Conditions for safe storage, including any incompatibilities

Storage Conditions	Store in cool, dry, well-ventilated area of non-combustible construction away from heavily
trafficked areas and emergency exits. Keep at temperatures below 52°C /  125°F. Cylinders should be stored upright with valve protection cap in place and firmly secured to prevent falling. Full and empty cylinders should be segregrated. Use a "first in-first out" inventory system to prevent full cylinders from being stored for excessive periods of time. Stored containers should be periodically checked for general condition and leakage.

Incompatible materials	None known.

8.	EXPOSURE CONTROLS/PERSONAL PROTECTION

Control parameters 	

Exposure Guidelines	This product, as supplied, does not contain any hazardous materials with occupational exposure
limits established by the region specific regulatory bodies
Appropriate engineering controls

Engineering Controls	Local exhaust ventilation to prevent accumulation of high concentrations and maintain air-oxygen
levels at or above 19.5%. Oxygen detectors should be used when asphyxiating gases may be released. Systems under pressure should be regularly checked for leakages.

Individual protection measures, such as personal protective equipment

Eye/ face protection	Wear safety glasses with side shields (or goggles).

Skin and body protection	Work gloves and safety shoes are recommended when handling cylinders.

Respiratory protection	Use positive pressure airline respirator with escape cylinder or self contained breathing apparatus
for oxygen-deficient atmospheres (<19.5%).

General Hygiene Considerations	Handle in accordance with good industrial hygiene and safety practice.
