Flammable liquified gas under pressure. Keep away from heat/sparks/flame/and all other ignition sources. Vapor replaces oxygen available for breathing and may cause suffocation on confined spaces. Use only with adequate ventilation. Reliance upon detection of odor may not provide adequate warning of potentially hazardous concentrations. Vapor is heavier than air; may collect at low levels. Liquid can cause freeze burn similar to frostbite. Do not get liquid in eyes on skim, or clothing. Avoid breathing vapor. Keep service valve closed when not in use.
