![]() The only way this diver will be crushed is when the water in the diver’s body solidifies. A skin suit or wetsuit won’t change this. No Pressure Suit means that we dive with the water touching our body all around and we only need to equalise our own air spaces. Depending on the suit worn a diver is subjected to variable degrees of crushing. Getting Crushed With vs Without A Pressure Suitĭiving often requires some form of exposure protection to be worn in order not to get too cold. These include differential pressure (saturation and off-gassing), gas toxicity and narcosis to mention a few. In order to answer, how deep can you dive before being crushed?, we are going to ignore the other limitations we face when diving to great depths. This prevents their air spaces from collapsing under pressure. They compensate for static water pressure by adding equal gas pressure into their air spaces as the atmospheric pressure of the depth they are diving in. Scuba divers and free divers rely on equalising to prevent damaging their bodies. For the purpose of this article we are assuming 1 bar for 10 meters of water.īecause water is virtually incompressible we are focusing on the crushing of air spaces within our body first. Boyle’s law states the linear relationship between depth, pressure, volume and density in water. Let’s look at the most basic physics that determine volume changes with pressure in an effort to work out how easily a diver’s air spaces could be crushed. The 40% of non-water non-gaseous minerals and tissues such as salts, proteins, fats and lipids are virtually impossible to compress similar to water. This is three times as deep as the deepest point in our ocean. This means we’d have to dive to about 35.5 km depth before bone crushes. Human bone crushes at about 11159 kg per square inch. But why is that? Read on for more information on how deep we can dive before being crushed!Ĭheck out how long freedivers can hold their breaths! How Deep Can you Dive Before Being Crushed? In short, a diver can’t simply be crushed by the weight of water. So, how deep can you dive before being crushed? ![]() The easiest to crush are our air spaces such as our middle ear, sinuses and our lungs. Air compartments surrounded by body tissue and the water percentile itself have different susceptibility to crushing. The human body consists of up to 60% water, leaving 40% of body tissue. There are a few factors to consider when trying to determine a diver’s “crush limit”. ![]()
