What should you do to avoid the primary hazard associated with oxygen exposure limits?

Staying within the limits set by your dive computer is crucial to avoid the primary hazard associated with oxygen exposure limits, which is oxygen toxicity. Dive computers typically provide real-time data on the percentage of oxygen in the breathing mix and calculate the maximum operating depth for purely oxygen breathing or enriched air dives. By adhering to these limits, divers can manage their exposure to elevated partial pressures of oxygen (ppO2), reducing the risk of harmful physiological effects.

Oxygen toxicity generally becomes a concern when ppO2 exceeds a specific threshold, typically around 1.4 atm for recreational diving. By using a dive computer that factors in the mix of gases, divers can ensure that they maintain safe limits throughout their dive. This approach promotes safety and enhances the diving experience, as divers can focus on their exploration without the constant worry of risking oxygen toxicity.

The other options lack relevance to managing oxygen exposure effectively. For instance, diving deeper than recommended does not contribute positively to safety and can actually increase the risk of encountering oxygen toxicity. Similarly, only diving in shallow water does not address the specific concern of oxygen exposure limits, as some shallow dives could still expose divers to high ppO2 levels without proper mix management. Using a different tank for each dive does not inherently reduce
