FIRE OR EXPLOSION HAZARD
CONDITIONS OF FLAMMABILITY: Nonflammable gas
MEANS OF EXTINCTION: Copious quantities of water for fires
with oxygen as the oxidizer.
FLASHPOINT AND METHOD OF Nonflammable gas
DETERMINATION:
UPPER EXPLOSION LIMIT (% BY VOL): Nonflammable gas
LOWER EXPLOSION LIMIT (% BY VOL): Nonflammable gas
AUTO-IGNITION TEMPERATURE: Nonflammable gas
FLAMMABILITY CLASSIFICATION: Nonflammable gas
HAZARDOUS COMBUSTION Nonflammable gas
PRODUCTS:
EXPLOSION DATA: Nonflammable gas
SENSITIVITY TO STATIC DISCHARGE: None
REACTIVITY DATA
CHEMICAL STABILITY: Stable as to decomposition
INCOMPATIBLE MATERIALS: All flammable materials, grease or
oils
CONDITIONS OF REACTIVITY: Reactive under various conditions,
temperature and pressure. All
elements, with the exception of the
inert gases react directly with
oxygen to form oxides. Reactivity
increases with temperature.
HAZARDOUS DECOMPOSITION None

TOXICOLOGICAL PROPERTIES
ROUTES OF ENTRY:
SKIN CONTACT: None
SKIN ABSORPTION: None
EYE: None
INHALATION: Breathing high concentrations greater than 75 molar per cent
causes symptoms of hyperoxia which include cramps, nausea, dizziness,
hypothermia, ambylopia, respiratory difficulties, bradycardia, fainting spells and
convulsions capable of leading to death. For additional data on hyperoxia as it
relates to oxygen pressure and exposure duration refer to Liquid Air's Gas
Encyclopedia.
Also known as a central nervous system toxin at concentrations of 100% O2 and
at elevated atmospheric pressures.
INGESTION: None
ACUTE OVER EXPOSURE EFFECTS: The property is that of hyperoxia which
leads to pneumonia. Concentrations between 25 and 75 molar percent present a
risk of inflammation of organic matter in the body.
CHRONIC OVER EXPOSURE EFFECTS: None
EXPOSURE LIMITS: No TWA is established (ACGIH 1995-1996). Oxygen is the
"vital element" in the atmosphere in which we live and breath (approximately 21
molar % of the atmosphere).
IRRITANCY OF PRODUCT: None
SENSITIZATION TO MATERIAL: None
CARCINOGENICITY, REPRODUCTIVE EFFECTS: None
TERATOGENICITY, MUTAGENICITY: None
TOXICOLOGICALLY SYNERGISTIC PRODUCTS: None
PREVENTIVE MEASURES
PERSONAL PROTECTIVE EQUIPMENT: Leather gloves. Safety goggles or
glasses. Safety shoes .
SPECIFIC ENGINEERING CONTROLS: Carbon steels and low alloy steels are
acceptable for use at lower pressures. For high pressure applications use
stainless steels, copper and its alloys, nickel and its alloys, brass, bronze, silicon
alloys, Monel庐, Inconel庐 or beryllium. Lead and silver or lead and tin alloys are
good gasketing materials. Teflon and Kel-F庐 are the preferred nonmetal gaskets.
Special Note: It should be recognized that the ignition temperature of metals and
nonmetals in pure oxygen service decreases with increasing oxygen pressure.
For additional information refer to Liquid Air's Gas Encyclopedia.
LEAK AND SPILL PROCEDURES: EVACUATE ALL PERSONNEL FROM
AFFECTED AREA.
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 MEGS location.
WASTE DISPOSAL: Do not attempt to dispose of waste or unused quantities.
Return in the shipping container properly labeled, with any valve outlet plugs or
caps secured and valve protection cap in place to MEGS for proper disposal. For
emergency disposal, contact the closest MEGS location.
HANDLING PROCEDURES AND EQUIPMENT: USE ONLY IN WELL-
VENTILATED AREAS.
Valve protection caps must remain in place unless container is secured with
valve outlet piped to the point of use. Do not drag, slide or roll cylinders. Use a
suitable hand truck for cylinder movement. Use a pressure reducing regulator
when connecting 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 into the
cylinder. Close valve after each use and when empty.
STORAGE REQUIREMENTS: Protect cylinders from physical damage. Store in
cool, dry, well-ventilated area of non combustible construction away from heavily
trafficked areas and emergency exits. Do not allow the temperature where
cylinders are stored to exceed 52掳C. 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.
TDG CLASSIFICATION: 2.2 (5.1)
WHMIS CLASSIFICATION: A, C
SPECIAL SHIPPING INFORMATION: Always secure cylinders in an upright
position before transporting them. NEVER transport cylinders in trunks of
vehicles, enclosed vans, truck cabs or in passenger compartments. Transport
cylinders secured in open flatbed or in open pick-up type vehicles.
FIRST AID MEASURES
SPECIFIC FIRST AID PROCEDURES: PROMPT MEDICAL ATTENTION IS
MANDATORY IN ALL CASES OF OVER EXPOSURE TO OXYGEN. RESCUE
PERSONNEL SHOULD BE COGNIZANT OF EXTREME FIRE HAZARD
ASSOCIATED WITH OXYGEN-RICH ATMOSPHERES.
INHALATION: Conscious persons should be assisted to an uncontaminated
area and breathe fresh air. They should be kept warm and quiet. The physician
should be informed that the victim is experiencing (has experienced) hyperoxia.
Unconscious persons should be moved to an uncontaminated area and given
assisted respiration. When breathing has been restored, treatment should be as
above. Continued treatment should be symptomatic and supportive.
EYE CONTACT: Not applicable
SKIN CONTACT: Not applicable
