The hazards of oxygen and oxygen-enriched mixtures

Safetygram 4 Gaseous hydrogen Hydrogen is a colorless, odorless, tasteless, highly flammable gas. It is also the lightest-weight gas. Since hydrogen is noncorrosive, special materials of construction are not normally required. Vessels and piping must be selected and designed to…

Safetygram 1 Gaseous oxygen Oxygen is the second largest component of the atmosphere, comprising 20.8% by volume. Gaseous oxygen is colorless, odorless, tasteless, and nonflammable. Oxygen is necessary to support life. It is a strong oxidizer that combines readily with…

Safetygram 16 Safe handling of cryogenic liquids A cryogenic liquid is defined as a liquid with a normal boiling point below –130°F (–90°C). The most commonly used industrial gases that are transported, handled, and stored in the liquid state at…

Safetygram 13 Acetylene Pure acetylene is a unique gas with hazards that arise from its high energy bonds and flammability. These same properties give acetylene its value as a high temperature cutting and welding gas with a very wide range…
