unconsciousness without warning and so rapidly that victim may be unable to
protect themselves.
Eye contact : No adverse effect.
Skin contact : No adverse effect.

Primary Routes of Entry : Inhalation
Target Organs : None known.
Symptoms : Exposure to oxygen deficient atmosphere may cause the following symptoms:
Dizziness. Salivation. Nausea. Vomiting. Loss of mobility/consciousness.
Aggravated Medical Condition
None.
Environmental Effects
Not harmful.
4. FIRST AID MEASURES
General advice : Remove victim to uncontaminated area wearing self contained breathing
apparatus. Keep victim warm and rested. Call a doctor. Apply artificial
respiration if breathing stopped.
Eye contact : Not applicable.
Skin contact : Not applicable.
Ingestion : Ingestion is not considered a potential route of exposure.
Inhalation : Remove to fresh air. If breathing has stopped or is labored, give assisted
respirations. Supplemental oxygen may be indicated. If the heart has stopped,
trained personnel should begin cardiopulmonary resuscitation immediately. In
case of shortness of breath, give oxygen.
5. FIRE-FIGHTING MEASURES
Suitable extinguishing media : All known extinguishing media can be used.
Specific hazards : Upon exposure to intense heat or flame, cylinder will vent rapidly and or rupture
violently. Product is nonflammable and does not support combustion. Move
away from container and cool with water from a protected position. Keep
containers and surroundings cool with water spray.
Special protective equipment : Wear self contained breathing apparatus for fire fighting if necessary.
for fire-fighters
6. ACCIDENTAL RELEASE MEASURES
Personal precautions : Evacuate personnel to safe areas. Wear self-contained breathing apparatus
when entering area unless atmosphere is proved to be safe. Monitor oxygen
level. Ventilate the area.
Environmental precautions : Do not discharge into any place where its accumulation could be dangerous.
Prevent further leakage or spillage if safe to do so.

Methods for cleaning up : Ventilate the area.
Additional advice : If possible, stop flow of product. Increase ventilation to the release area and
monitor oxygen level. If leak is from cylinder or cylinder valve, call the Air
Products emergency telephone number. If the leak is in the user鈥檚 system,
close the cylinder valve, safely vent the pressure, and purge with an inert gas
before attempting repairs.
7. HANDLING AND STORAGE
Handling
Protect cylinders from physical damage; do not drag, roll, slide or drop. Do not allow storage area temperature
to exceed 50掳C (122掳F). Only experienced and properly instructed persons should handle compressed gases.
Before using the product, determine its identity by reading the label. Know and understand the properties and
hazards of the product before use. When doubt exists as to the correct handling procedure for a particular gas,
contact the supplier. Do not remove or deface labels provided by the supplier for the identification of the cylinder
contents. When moving cylinders, even for short distances, use a cart (trolley, hand truck, etc.) designed to
transport cylinders. Leave valve protection caps in place until the container has been secured against either a
wall or bench or placed in a container stand and is ready for use. Use an adjustable strap wrench to remove
over-tight or rusted caps. Before connecting the container, check the complete gas system for suitability,
particularly for pressure rating and materials. Before connecting the container for use, ensure that back feed
from the system into the container is prevented. Ensure the complete gas system is compatible for pressure
rating and materials of construction. Ensure the complete gas system has been checked for leaks before use.
Employ suitable pressure regulating devices on all containers when the gas is being emitted to systems with
lower pressure rating than that of the container. Never insert an object (e.g. wrench, screwdriver, pry bar, etc.)
into valve cap openings. Doing so may damage valve, causing a leak to occur. Open valve slowly. If user
experiences any difficulty operating cylinder valve discontinue use and contact supplier. Close container valve
after each use and when empty, even if still connected to equipment. Never attempt to repair or modify
container valves or safety relief devices. Damaged valves should be reported immediately to the supplier. Close
valve after each use and when empty. Replace outlet caps or plugs and container caps as soon as container is
disconnected from equipment. Do not subject containers to abnormal mechanical shocks which may cause
damage to their valve or safety devices. Never attempt to lift a cylinder by its valve protection cap or guard. Do
not use containers as rollers or supports or for any other purpose than to contain the gas as supplied. Never
strike an arc on a compressed gas cylinder or make a cylinder a part of an electrical circuit. Do not smoke while
handling product or cylinders. Never re-compress a gas or a gas mixture without first consulting the supplier.
Never attempt to transfer gases from one cylinder/container to another. Always use backflow protective device
in piping. When returning cylinder install valve outlet cap or plug leak tight. Never use direct flame or electrical
heating devices to raise the pressure of a container. Containers should not be subjected to temperatures above
50掳C (122掳F). Prolonged periods of cold temperature below -30掳C (-20掳F) should be avoided.
Storage
Full containers should be stored so that oldest stock is used first. Containers should be stored in a purpose build
compound which should be well ventilated, preferably in the open air. Stored containers should be periodically
checked for general condition and leakage. Observe all regulations and local requirements regarding storage of
containers. Protect containers stored in the open against rusting and extremes of weather. Containers should
not be stored in conditions likely to encourage corrosion. Containers should be stored in the vertical position and
properly secured to prevent toppling. The container valves should be tightly closed and where appropriate valve
outlets should be capped or plugged. Container valve guards or caps should be in place. Keep containers tightly
closed in a cool, well-ventilated place. Store containers in location free from fire risk and away from sources of
heat and ignition. Full and empty cylinders should be segregated. Do not allow storage temperature to exceed
50掳C (122掳F). Return empty containers in a timely manner.

Technical measures/Precautions
Containers should be segregated in the storage area according to the various categories (e.g. flammable, toxic,
etc.) and in accordance with local regulations. Keep away from combustible material.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering measures
Provide natural or mechanical ventilation to prevent oxygen deficient atmospheres below 19.5% oxygen.
Personal protective equipment
Respiratory protection : Self contained breathing apparatus (SCBA) or positive pressure airline with
mask are to be used in oxygen-deficient atmosphere. Air purifying respirators
will not provide protection. Users of breathing apparatus must be trained.
Hand protection : Sturdy work gloves are recommended for handling cylinders.
The breakthrough time of the selected glove(s) must be greater than the
intended use period.
Eye protection : Safety glasses recommended when handling cylinders.
Skin and body protection : Safety shoes are recommended when handling cylinders.
Special instructions for : Ensure adequate ventilation, especially in confined areas.
