Personal precautions : Evacuate personnel to safe areas. Remove all sources of ignition. Never enter
a confined space or other area where the flammable gas concentration is
greater the 10% of its lower flammable limit. Ventilate the area.
Environmental precautions Should not be released into the environment. Do not discharge into any place
where its accumulation could be dangerous. Prevent from entering sewers,
basements and workpits, or any place where its accumulation can be
dangerous. Prevent further leakage or spillage if safe to do so.
Methods for cleaning up Keep area evacuated and free from ignition sources until any spilled liquid has
evaporated. (Ground free from frost). Ventilate the area. Approach suspected
leak areas with caution.
Additional advice If possible, stop flow of product. If leak is from cylinder or cylinder 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 purge with an inert gas
before attempting repairs. Increase ventilation to the release area and monitor
concentrations.
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°C (122°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. Purge air from system before introducing gas. 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°C (122°F). Prolonged periods of cold temperature below -
30°C (-20°F) should be avoided. Never attempt to increase liquid withdrawal rate by pressurizing the container
without first checking with the supplier. Never permit liquefied gas to become trapped in parts of the system as
this may result in hydraulic rupture. All piped systems and associated equipment must be grounded.
S
torage
Containers should be stored in a purpose build compound which should be well ventilated, preferably in the
open air. Full containers should be stored so that oldest stock is used first. Observe all regulations and local
requirements regarding storage of containers. Stored containers should be periodically checked for general
condition and leakage. 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°C (122°F). Smoking should be prohibited within storage areas or while
handling product or containers. Display "No Smoking or Open Flames" signs in the storage areas. The amounts
of flammable or toxic gases in storage should be kept to a minimum. Return empty containers in a timely
manner. Flammable storage areas should be separated from oxygen and other oxidizers by a minimum distance
of 20 ft. (6.1 m.) or by a barrier of non-combustible material at least 5 ft. (1.5 m.) high, having a fire resistance
rating of at least 1/2 hour.
T
echnical 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. All electrical equipment in
the storage areas should be compatible with flammable materials stored. Containers containing flammable
gases should be stored away from other combustible materials. Where necessary containers containing oxygen
and oxidants should be separated from flammable gases by a fire resistant partition.
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering measures
Provide natural or explosion-proof ventilation that is adequate to ensure flammable gas does not reach its lower
explosive limit.
Personal protective equipment
Respiratory protection : High concentrations that can cause rapid suffocation are within the flammable
range and should not be entered.
