SECTION 7. HANDLING AND STORAGE

Handling (Personnel) :

Use sufficient ventilation to keep employee exposure below recommended

limits. For personal protection see section 8.

Handle in accordance with good industrial hygiene and safety practice.

Handling (Physical Aspects) :

The product should not be mixed with air for leak testing or used with air for

any other purpose above atmospheric pressure. Contact with chlorine or

other strong oxidizing agents should also be avoided.

Storage :

Valve protection caps and valve outlet threaded plugs must remain in place

unless container is secured with valve outlet piped to use point. Do not drag,

slide or roll cylinders. Use a suitable hand truck for cylinder movement. Use a

pressure reducing regulator when connecting cylinder to lower pressure

(>3000 psig) piping or systems. Never attempt to lift cylinder by its cap. Use a

check valve or trap in the discharge line to prevent hazardous back flow into

the cylinder. Cylinders should be stored upright and firmly secured to

prevent falling or being knocked over.

Separate full containers from empty containers. Keep at temperature not

exceeding 52°C. Do not store near combustible materials. Avoid area where

salt or other corrosive materials are present.

Storage temperature :

< 52 °C (< 126 °F)

SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Engineering controls :

Normal ventilation for standard manufacturing procedures is generally

adequate. Local exhaust should be used when large amounts are released.

Mechanical ventilation should be used in low or enclosed places. Refrigerant

concentration monitors may be necessary to determine vapour concentrations

in work areas prior to use of torches or other open flames, or if employees are

entering enclosed areas.

Personal protective equipment

Respiratory protection :

For rescue and maintenance work in storage tanks use self-contained

breathing apparatus. Vapours are heavier than air and can cause suffocation

by reducing oxygen available for breathing.

Hand protection :

Additional protection: Impervious gloves
