Handling and storage

Precautions for safe handling

Precautions for safe handling : Do not breathe gas/vapor. Avoid all contact with skin, eyes, or clothing. Emergency eye wash

fountains and safety showers should be available in the immediate vicinity of any potential

exposure

Wear leather safety gloves and safety shoes when handling cylinders.

Protect cylinders from physical damage; do not drag, roll, slide or drop. While moving cylinder, always keep in place

removable valve cover.

Never attempt to lift a cylinder by its cap; the cap is intended solely to

protect the valve.

When moving cylinders, even for short distances, use a cart (trolley, hand

truck, etc.) designed to transport cylinders.

Never insert an object (e.g, wrench, screwdriver,pry bar) into cap openings; doing so may damage the valve and cause a leak.

Use an adjustable strap wrench to remove over-tight or rusted caps. Slowly open the valve.

If the valve is hard to open, discontinue use and contact your supplier.

Close the container valve after each use; keep closed even when empty.

Never apply flame or localized heat directly to

any part of the container.

High temperatures may damage the container and could cause the

pressure relief device to fail prematurely, venting the container contents.

For other precautions in using this product, see section 16.

Conditions for safe storage, including any incompatibilities

Storage conditions :

Avoid oil, grease and all other combustible materials

Store only where temperature will not exceed 125°F (52°C). Post “No Smoking/No Open

Flames” signs in storage and use areas. There must be no sources of ignition. Separate

packages and protect against potential fire and/or explosion damage following appropriate

codes and requirements (e.g, NFPA 30, NFPA 55, NFPA 70, and/or NFPA 221 in the U.S.) or

according to requirements determined by the Authority Having Jurisdiction (AHJ). Always

secure containers upright to keep them from falling or being knocked over. Install valve

protection cap, if provided, firmly in place by hand when the container is not in use. Store full

and empty containers separately. Use a first-in, first-out inventory system to prevent storing full

containers for long periods. For other precautions in using this product, see section 16

OTHER PRECAUTIONS FOR HANDLING, STORAGE, AND USE: When handling product

under pressure, use piping and equipment adequately designed to withstand the pressures to

be encountered. Never work on a pressurized system. Use a back flow preventive device in the

piping. Gases can cause rapid suffocation because of oxygen deficiency; store and use with

adequate ventilation. If a leak occurs, close the container valve and blow down the system in a

safe and environmentally correct manner in compliance with all international, federal/national,

state/provincial, and local laws; then repair the leak. Never place a container where it may

become part of an electrical circuit.

Gas group : Liquefied gas

Additional information : Gas/vapor heavier than air. May accumulate in confined spaces, particularly at or below ground

level

Symptoms/injuries after inhalation :

Overexposure to concentrations moderately above the TLV of 1 ppm irritates the eyes and

respiratory tract. Very brief exposure to a concentration of 1000 ppm may be fatal. Acts as an

asphyxiant at high concentrations. Inhalation of high concentrations (e.g, greater than 15 ppm)

causes choking, coughing, burning of the throat, and severe irritation of the upper respiratory

tract; additionally, pulmonary edema, bronchitis, and pneumonitis may result.

Special transport precautions :

Avoid transport on vehicles where the load space is not separated from the driver's

compartment. Ensure vehicle driver is aware of the potential hazards of the load and knows

what to do in the event of an accident or an emergency. Before transporting product containers:

- Ensure there is adequate ventilation. - Ensure that containers are firmly secured. - Ensure

cylinder valve is closed and not leaking. - Ensure valve outlet cap nut or plug (where provided)

is correctly fitted. - Ensure valve protection device (where provided) is correctly fitted.

For this reason, chlorine may be safely stored in metal containers, usually steel. Moist chlorine corrodes most metals rapidly and therefore it is of utmost importance that all containers, pipes and equipment used to transport chlorine gas away from cylinders should be dry and clean. ... Steel cylinders containing 1 ton.

Chlorine is typically shipped and stored as a liquid in a container under pressure. The maximum-sized container (at least in the United States ) shipped by rail is capable of holding 90 tons of liquid chlorine. ... This is an uneconomical way of shipping and storing chlorine. But if the gas is pressurized, it will liquefy.
