What is the longest snorkel you can use?
The maximum length for a snorkel without compromising safety is 16 inches. Again, therefore a garden hose at a minimum of 25 feet in length would be considered unsafe: 25 feet is way longer than a traditional snorkel’s 16 inches!
What causes death while snorkeling?
Preliminary data from a study released last week suggested that oxygen deprivation induced by rapid onset pulmonary edema, known as ROPE, is the most probable cause of snorkel-related fatal and near-fatal drownings. Drowning by ROPE is different in that a person doesn’t necessarily have to be inhaling water.
How deep underwater can you breathe through a tube?
You can only go a few feet under water before you’ll no longer be able to draw air into your lungs through that hose. It’s a pressure problem. The water pressure outside your chest increases rapidly as you go deeper, but the air pressure inside the hose and your mouth barely changes at all.
How long can I last under water?
Without the supply of oxygen, the body shuts down. The average person can hold their breath for around 30 seconds. For children, the length is even shorter. A person who’s in excellent health and has training for underwater emergencies can still usually hold their breath for only 2 minutes.
