Safety Information

High-pressure oxidizing gas.

Vigorously accelerates combustion.

In its most well-known form (it constitutes 21% of the atmosphere), it is a tasteless, odorless and colorless gas essential to life. Oxygen provides several applications on the different sectors of our lives, being often used on combustion processes, welding, oxygenation, water treatment and fish farming. It is also used on environments with controlled atmospheres (submarines, airplanes, space ships, high depth land mines) and on diving. Main Application
