: In case of fire, use water spray (fog), foam, dry chemicals, or CO 2.
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 6. Accidental release measures
: Immediately contact emergency personnel. Keep unnecessary personnel away. Use
Personal precautions
suitable protective equipment (Section 8). Shut off gas supply if this can be done safely.
Isolate area until gas has dispersed.
Environmental precautions : Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains
and sewers.
Section 7. Handling and storage
: Do not ingest. Keep container closed. Use only with adequate ventilation. Keep away
Handling
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.
