Fire fighting media and
instructions
If involved in fire, shut off flow immediately if it can be done without risk. Apply water
from a safe distance to cool container and protect surrounding area.
Extremely flammable. Gas may accumulate in confined areas, travel considerable
distance to source of ignition and flash back causing fire or explosion.

Section 7. Handling and storage
: Avoid contact with eyes, skin and clothing. Keep container closed. Use only with
Handling
adequate ventilation. Keep away from heat, sparks and flame. To avoid fire, minimize
ignition sources. Use explosion-proof electrical (ventilating, lighting and material
handling) equipment. Do not puncture or incinerate container. Wash thoroughly after
handling. High pressure gas. Use equipment rated for cylinder pressure. Close valve
after each use and when empty. Protect cylinders from physical damage; do not drag,
roll, slide, or drop. Use a suitable hand truck for cylinder movement.
: Keep container tightly closed. Keep container in a cool, well-ventilated area. Cylinders
Storage
should be stored upright, with valve protection cap in place, and firmly secured to
prevent falling or being knocked over. Cylinder temperatures should not exceed 52 癈
(125 癋).
Section 8. Exposure Controls, Personal Protection
: Use only with adequate ventilation. Use process enclosures, local exhaust ventilation, or
Engineering controls
other engineering controls to keep airborne levels below recommended exposure limits.
The engineering controls also need to keep gas, vapor or dust concentrations below any
explosive limits. Use explosion-proof ventilation equipment.
