What equipment must be used with Nitrox to ensure safety?

Using Nitrox for diving requires equipment that is specifically designed or designated as compatible with higher concentrations of oxygen. This is essential because the presence of increased oxygen levels can lead to a risk of fire and equipment degradation. Nitrox-compatible regulators and tanks are constructed using materials that can withstand the effects of oxygen-rich environments, ensuring both the integrity of the equipment and the safety of the diver.

When it comes to other options, standard scuba tanks may not be suitable for Nitrox as they could have residual oils or contaminants from previous uses, increasing the risk of combustion. Equipment like weight belts and fins, while necessary for scuba diving in general, do not directly pertain to the safe handling of Nitrox. Likewise, surface markers and beacons are used for signaling and navigation but do not impact the safe use of Nitrox itself. Thus, choosing Nitrox-compatible regulators and tanks is crucial for divers wishing to use this gas safely.
