In terms of safety, why is it critical that oxygen equipment be kept away from oil and grease?

  1. It preserves the equipment life

  2. It is a fire hazard

  3. It helps maintain pressure

  4. It prevents rusting

The correct answer is: It is a fire hazard

Keeping oxygen equipment away from oil and grease is critically important due to the significant fire hazard it presents. When oil and grease come into contact with high concentrations of oxygen, particularly in pressurized systems, the potential for combustion increases dramatically. This is because oxygen supports combustion, and in the presence of a combustible material like oil or grease, even a small spark can ignite a fire or cause an explosion. Oxygen-enriched environments can cause materials that are normally regarded as safe or non-flammable to ignite easily and burn rapidly. Understanding this safety measure is essential for anyone involved in handling oxygen equipment, as it emphasizes the need for strict protocols and diligence in maintaining a safe working environment. The prevention of fire incidents directly correlates to the proper storage and management of oxygen equipment, highlighting the importance of cleanliness and adherence to safety regulations in all settings where oxygen is used.
