class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>A <strong>SAFETY STOP<\/strong> adds additional conservatism to your no-stop\/NDL dive by allowing additional nitrogen off-gassing before you surface. It isn&#8217;t compulsory but is highly recommended. Safety stops can be skipped if more pressing safety factors dictate that you should surface immediately.<\/p>\n\n\n\n<p>In contrast, a <strong><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/understanding-m-values-eric-baker\/\">DECOMPRESSION<\/a> STOP<\/strong> is a mandatory stop to allow sufficient nitrogen off-gassing so that you can surface without unreasonable risk of <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/types-decompression-sickness-dcs\/\">decompression illness<\/a> (DCI). Essentially, you cannot surface until the decompression stop, or stops, are completed.<\/p>\n\n\n\n<p class=\"has-confident-cloud-gradient-background has-background\"><strong>In short, if you miss a safety stop you have a reasonable chance of being fine. Whereas if you miss a decompression stop you have a <em>reasonable chance of getting bent<\/em>.<\/strong><\/p>\n\n\n\n<p>Recreational diving ensures that you always have immediate and direct access to the surface in the event of emergencies. As such, recreational divers are not trained or certified to conduct decompression stops.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Dives that involve decompression stops are called TECHNICAL dives. <\/li>\n\n\n\n<li>The training for <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/what-is-technical-diving\/\">technical diving<\/a> is far more comprehensive and demanding than what recreational divers do. <\/li>\n\n\n\n<li>Additionally, technical divers utilize specialist equipment, gasses, complex planning, and protocols to mitigate increased risks on their dives.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/05\/Andy-Davis-Sidemount-Diving-111-edited-1024x576.jpg\" alt=\"Safety stop after a recreational dive\" class=\"wp-image-24747\" srcset=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/05\/Andy-Davis-Sidemount-Diving-111-edited-1024x576.jpg 1024w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/05\/Andy-Davis-Sidemount-Diving-111-edited-300x169.jpg 300w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/05\/Andy-Davis-Sidemount-Diving-111-edited-768x432.jpg 768w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/05\/Andy-Davis-Sidemount-Diving-111-edited-250x141.jpg 250w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/05\/Andy-Davis-Sidemount-Diving-111-edited.jpg 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">The author, with a student, performing a safety stop on ascent from a recreational training dive.<\/figcaption><\/figure>\n\n\n\n<div class=\"scuba-b4-h2-2\" style=\"margin-top: 10px;margin-bottom: 10px;\" id=\"scuba-544359329\"><div class=\"scuba-adlabel\">Sponsored Link<\/div><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-9354033900485448\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-9354033900485448\" \ndata-ad-slot=\"2393012471\" \ndata-ad-format=\"auto\" data-full-width-responsive=\"false\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div><h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What-are-Safety-Stops\"><\/span>What are Safety Stops?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>A safety stop is an essential and universally adopted procedure within the world of scuba diving. It&#8217;s a brief pause in shallow water during a scuba diver&#8217;s ascent to the surface following a dive. <\/p>\n\n\n\n<p>This pause, usually performed at a depth ranging from approximately 15 to 20 feet (5 to 6 meters), is typically for around 3 minutes. <\/p>\n\n\n\n<p>Some dive training agencies teach more complex safety stop protocols. For instance, with 3 stops at 9m (30ft), 6m (20ft), and 3m (10ft). This adds further safety from DCS, especially on deeper recreational dives.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" width=\"812\" height=\"463\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/08\/RAID-Ascent.png\" alt=\"Safety stop procedures taught on the RAID Advanced35 (AOW) course\" class=\"wp-image-25298\" srcset=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/08\/RAID-Ascent.png 812w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/08\/RAID-Ascent-300x171.png 300w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/08\/RAID-Ascent-768x438.png 768w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/08\/RAID-Ascent-250x143.png 250w\" sizes=\"(max-width: 812px) 100vw, 812px\" \/><figcaption class=\"wp-element-caption\">Safety stop procedures taught on the <a href=\"https:\/\/scubatechphilippines.com\/raid-diving-courses-philippines\/raid-advanced-35\/\">RAID Advanced35<\/a> (AOW) course.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What-is-the-purpose-of-safety-stops\"><\/span>What is the purpose of safety stops? <span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Divers conduct safety stops to add an extra layer of conservatism by allowing the further release of nitrogen from their bodies before surfacing. <\/p>\n\n\n\n<p>In turn, this reduces the risk of <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/types-decompression-sickness-dcs\/\">decompression sickness<\/a> (DCS).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/a-simple-guide-to-dive-computer-algorithms\/\">Computer and table No-Stop (No-Deco) Limits are calculated to keep most divers safe<\/a>, most of the time.
