PADI Divemaster Certification Practice Exam

What primary concern should be taken into account for cold dives?

1. Divers usually dive with more than one tank

2. Diver comfort and hypothermia

3. Using traditional wetsuits instead of dry suits

4. There are no concerns in cold water

The correct answer is: Diver comfort and hypothermia

The primary concern during cold dives is diver comfort and the risk of hypothermia. Cold water can significantly impact a diver’s physical state and ability to perform, making it crucial to maintain body temperature during dives. Hypothermia can occur when a diver is exposed to cold water for extended periods, leading to decreased motor functions, impaired decision-making, and increased risk of accidents. When planning for cold dives, it’s important for divers to be equipped with suitable thermal protection appropriate for the water temperature, which can include dry suits or appropriately thick wetsuits that minimize heat loss. This gear helps maintain core body temperature and overall comfort, allowing divers to focus on their diving tasks rather than battling the cold. The design and fit of the wetsuit or dry suit are also essential in providing insulation and protection against the elements. While divers may sometimes carry more than one tank or opt for traditional wetsuits, these factors are secondary to addressing the immediate and potentially dangerous impact that cold conditions can have on a diver’s safety and comfort. Cold water presents specific challenges that require careful consideration and preparation to ensure a safe diving experience.
