Move away from container and cool with water from a prot ected position. If possible, stop flow of product. Keep adjacent cylinders cool by spraying with large

amounts of water until the fire burns itself out. M ost cylinders are designed to vent contents when exposed to elevated temperature s.

Special protective equipment for fire-fighters : Wear self contained breathing apparatus for fire fi ghting if necessary.



### 6. ACCIDENTAL RELEASE MEASURES

Personal precautions : Monitor carbon dioxide level. Evacuate personnel to safe areas. Wear self-contained breathing apparatus when entering ar ea unless atmosphere is proved to be safe. Ventilate the area. Monitor oxyg en level.

Environmental precautions : Should not be released into the environment. Do not discharge into any place where its accumulation could be dangerous. Prevent further leakage or spillage. Prevent from entering sewers, basements and workpit s, or any place where its accumulation can be dangerous.

Methods for cleaning up : Ventilate the area.

Additional advice : If possible, stop flow of product. Increase ventila tion to the release area and monitor oxygen level. If leak is from cylinder or c ylinder valve, call the Air Products emergency telephone number. If the leak is in the user's system, close the cylinder valve, safely vent the pressure, and p urge with an inert gas before attempting repairs.



### 7. HANDLING AND STORAGE

Handling

Only experienced and properly instructed persons sh ould handle compressed gases/cryogenic liquids. Pro tect cylinders from physical damage; do not drag, roll, slide or drop. Do not allow storage area temperatur e to exceed 50°C (122°F). Before using the product, determine i ts identity by reading the label. Know and understa nd the properties and hazards of the product before use. When doubt exists as to the correct handling proced ure 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 truc k, etc.) designed to transport cylinders. Leave valve protec tion caps in place until the container has been sec ured against either a wall or bench or placed in a container sta nd and is ready for use. Use an adjustable strap wr ench to remove over-tight or rusted caps. Before connecting the container, check the complete gas system for s uitability, particularly for pressure rating and materials. Bef ore connecting the container for use, ensure that b ack 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 f or leaks before use. Empl oy suitable pressure regulating devices on all contain ers when the gas is being emitted to systems with l ower pressure rating than that of the container. Never i nsert 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 experienc es 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. N ever attempt to repair or modify container valves o r safety

4/8 Air Products and Chemicals,Inc Carbon Dioxide relief devices. Damaged valves should be reported i mmediately to the supplier. Close valve after each use and when empty. Replace outlet caps or plugs and contai ner caps as soon as container is disconnected from equipment. Do not subject containers to abnormal me chanical shocks which may cause damage to their val ve or safety devices. Never attempt to lift a cylinder by its valve protection cap or guard. Always use back flow protective device in piping. When returning cylinder install v alve outlet cap or plug leak tight. Never use direc t flame or electrical heating devices to raise the pressure of a container. Containers should not be subjected to temperatures above 50°C (122°F). Prolonged periods of cold tempe rature below -30°C (-20°F) should be avoided. Never attempt to increase liquid withdrawal rate by press urizing the container without first checking with t he supplier. Never permit liquefied gas to become trapped in par ts of the system as this may result in hydraulic ru pture.



### Storage

Full containers should be stored so that oldest s t ock is used first. Containers should be stored in t he vertical position and properly secured to prevent toppling. The container valves should be tightly closed and w here appropriate valve outlets should be capped or plugg ed. Container valve guards or caps should be in pla ce. Observe all regulations and local requirements rega rding storage of containers. Stored containers shou ld be periodically checked for general condition and leak age. Protect containers stored in the open against rusting and

extremes of weather. Containers should not be store d in conditions likely to encourage corrosion. Cont ainers should be stored in a purpose build compound which should be well ventilated, preferably in the open a ir. Keep containers tightly closed in a cool, well-ventilate d place. Store containers in location free from fir e risk and away from sources of heat and ignition. Full and empty c ylinders should be segregated. Do not allow storage temperature to exceed 50°C (122°F). Return empty co ntainers in a timely manner.



### Technical measures/Precautions

Containers should be segregated in the storage area according to the various categories (e.g. flammabl e, toxic, etc.) and in accordance whit local regulations. Kee p away from combustible material.



### 8. EXPOSURE CONTROLS / PERSONAL PROTECTION

Engineering measures

Provide natural or mechanical ventilation to preven t accumulation above exposure limits. Provide natural or mechanical ventilation to prev e nt oxygen deficient atmospheres below 19.5% oxygen.



### Personal protective equipment

Respiratory protection : Self contained breathing apparatus (SCBA) or positi ve pressure airline with mask are to be used in oxygen-deficient atmosphere. Air purifying respirators will not provide protect ion. Users of breathing apparatus

must be trained.
