Is it acceptable for EANx divers to use any EANx cylinder available?

Yes, it's always acceptable
No, it must be specific to their mix
Yes, but only in emergencies
No, they should always check compatibility

The correct answer is: No, it must be specific to their mix

When it comes to using enriched air nitrox (EANx) cylinders, it is essential that divers use a cylinder that is specific to their gas mix. Each EANx cylinder is filled with a particular percentage of oxygen and nitrogen, which affects the maximum operating depth and the overall dive plan. Utilizing a cylinder not specifically filled for the intended mixture could lead to serious consequences, including increased risk of oxygen toxicity if using a higher oxygen mix than intended. Divers must also be aware that different concentrations of oxygen can have various requirements for the handling, filling, and maintenance of cylinders. For example, a cylinder filled with a higher percentage of oxygen needs to be serviced and maintained in a way that prevents contamination and ensures safety. While safety protocols can vary, ensuring that the gas mix corresponds to the cylinder being used is a fundamental aspect of diving procedures for EANx. This enhanced awareness and adherence to safety standards serve to protect divers and enhance the quality of their diving experiences.
