When should oxygen bottles be filled?

Filling oxygen bottles below a pressure of 1,000 psi for small bottles ensures that they are kept in a safe operating range. This practice helps maintain the integrity of the bottles and guarantees that they have enough pressure to provide adequate oxygen supply when needed. Additionally, refilling at this level prevents the risk of operating with an empty or near-empty bottle, which could be dangerous during fire and rescue operations.

The safety protocols regarding oxygen bottle pressures are established to ensure that firefighters and rescue personnel have reliable access to oxygen. Small bottles generally have less capacity, so filling them when they go below 1,000 psi ensures that they are kept at a sufficient pressure for immediate use, thereby promoting both safety and efficiency in emergency situations.
