Ingestion Ingestion is not an observed route of exposure to gaseous hazardous materials. Consider diuresis, hemodialysis, peritoneal dialysis and exchange transfusions. Not applicable, this material is a gas. This material may propagate a decomposition flame without air. Heating cylinder to the point of activation of the pressure relief device or to the point of initiating decomposition.
Thermal decomposition releases hydrogen.
The only safe way to extinguish a flammable gas fire is to stop the flow of gas. If the flow cannot be stopped, allow the entire contents of the cylinder to burn. Cool the cylinder and surroundings with water from a suitable distance. Extinguishing the fire without stopping the flow of gas may permit the formation of ignitable or explosive mixtures with air. These mixtures may propagate to a source of ignition.
