Diving beyond this limit or using the system without proper knowledge of underwater safety can lead to dangerous conditions, such as:

• Barotrauma

• Decompression Sickness (DCS)

• Lung Overexpansion

• Oxygen Toxicity

• Shallow Water Blackout

• Arterial Gas Embolism (AGE)

• Nitrogen Narcosis

To minimize risks, SCUBA certification or diving training from organizations like PADI®, SSI®, or NAUI® is highly recommended.
