Deep Dive: An Interview with Dr Hanna Van Waart
Episode Notes Research, CPSC Warning, and Manufacturer Responsibility Hanna Van Waart PhD Exercise Physiologist at the University of Aukland discussed full face mask safety, her research and manufacturer’s responsibility The research article, “Full-face snorkel masks increase the incidence of hypoxemia and hypercapnia during simulated snorkeling compared to conventional snorkels,” was published in Diving and Hyperbaric Medicine in December 2023. The study was led by Janneke Grundemann, with coauthors Xavier C.E. Vrijdag, Nicole Y.E. Wong, Nicholas Gant, Simon J. Mitchell, and Hanna van Waart. Hanna van Waart is affiliated with the Department of Anesthesiology at the University of Auckland. The research team examined whether full-face snorkel masks increase the risk of rebreathing, elevated carbon dioxide, and reduced oxygen levels compared with a conventional snorkel. In the controlled study, 20 healthy participants used two different full-face snorkel masks and a conventional snorkel under seated, light-exercise, and moderate-exercise conditions. The researchers found that full-face snorkel mask trials were stopped more often because end-tidal carbon dioxide exceeded the safety threshold. During light exercise, 18 of 40 full-face mask trials were stopped compared with 4 of 20 conventional snorkel trials. During moderate exercise, 9 of 22 full-face mask trials were stopped compared with 3 of 16 conventional snorkel trials. The main concern identified by the study is rebreathing caused by non-unidirectional airflow. Full-face snorkel masks are designed to separate inhaled and exhaled air, but the researchers found evidence that this separation was not consistently maintained. Carbon dioxide and oxygen levels in the eye pockets of the masks fluctuated in a way that showed rebreathing in all full-face mask wearers. This means users may rebreathe exhaled air, leading to hypercapnia, which is elevated carbon dioxide, and hypoxemia, which is reduced oxygen in the blood. Traditional snorkels also carry some risk of carbon dioxide buildup, but they allow users to clear the snorkel tube, remove the mouthpiece, or take fresh breaths more easily. Full-face snorkel masks can be harder to remove and may delay access to fresh air, especially if a person is tired, panicked, or already experiencing symptoms from rising carbon dioxide. Because concerning findings occurred in healthy adults, the risk may be greater for children, older adults, and people with underlying heart or lung conditions. There are also fitting issue. Not everyone has the same face, and smaller faces may have worse fit and there is also the factor of individual lung capacity. These research concerns are reinforced by recent action from the U.S. Consumer Product Safety Commission. In 2026, the CPSC warned consumers to stop using OUSPT full-face snorkel masks immediately because of the risk of serious injury and death from drowning. The CPSC stated that the mask can cause labored breathing, loss of consciousness, excess fluid in the lungs, and increased carbon dioxide levels that can worsen breathing difficulty. The agency also reported five consumer incidents involving trouble breathing, lightheadedness, or loss of consciousness, as well as one lawsuit alleging that the product caused a drowning fatality. Approximately 84,000 OUSPT masks were sold on Amazon between March 2019 and February 2026, and consumers were advised to stop using and dispose of the masks rather than sell or give them away. Taken together, the Diving and Hyperbaric Medicine study and the CPSC warning support a stronger safety message: full-face snorkel masks should not be treated simply as recreational toys. They function as breathing apparatuses because they control how a person inhales and exhales while face-down in the water. For that reason, manufacturers should carry the responsibility to prove these products are safe through rigorous design testing, independent evaluation, and appropriate regulatory standards before they are marketed broadly to residents, visitors, families, and children. The practical safety message is that snorkelers should use simple, well-fitted equipment, snorkel with a buddy, take regular fresh-air breaks, and avoid full-face snorkel masks, especially for children, older adults, and people with medical risk factors.

Deep Dive: An Interview with Drasko Bogdanovic and Dr. Justin Sempsrott
Episode Notes Inside the Roundup: Drasko Bogdanovic and Dr. Justin Sempsrott on the Critical Minutes That Save Lives — “Micro Delays Matter” This episode of Deep Dive Into Water Safety focused on what happens in the first minutes after a drowning rescue and why those moments can determine survival long before someone reaches a hospital. Returning guests Drasko Bogdanovic and Dr. Justin Sempsrott discussed the San Luis Obispo “Roundup,” a large scale rescue training event that brought together more than 250 first responders, including lifeguards, EMS, firefighters, and rescue personnel from Costa Rica, Mexico, and New Zealand. The goal was not classroom learning. It was stress exposure and muscle memory. Responders trained in cold, wind, wet gear, helicopter wash, long carries, radio coordination, and the confusion that follows a real rescue. The training centered around something Dr. Sempsrott often says in drowning response: “micro delays matter.” A major part of the discussion focused on how drowning differs from many other cardiac arrest situations. Dr. Sempsrott explained why oxygenation and ventilations are critical in drowning cases, especially pediatric hypoxic arrests, and why actions taken by lifeguards and bystanders can shape outcomes before EMS even arrives. He also reinforced the importance of CPR for parents and the public that includes both breaths and compressions in drowning emergencies. Hawaiʻi’s drowning standing orders currently list oxygen as the first intervention. The conversation also focused on the role of lifeguards within emergency response systems. Drasko Bogdanovic and Dr. Sempsrott argued that lifeguards routinely perform advanced airway and resuscitation skills in uncontrolled environments, yet are often overlooked in funding, planning, and emergency response discussions. The conversation also turned to larger problems in drowning prevention, including inconsistent data collection, underreporting of nonfatal drownings, and the difficulty of tracking long term outcomes after rescue. Prevention remained a constant theme throughout the episode, including public education, supervision, CPR training, engineering solutions, and stronger coordination between agencies. The episode ended with discussion about how to keep building these programs, including expanding simulation training, strengthening partnerships with organizations including the CDC and the International Drowning Research Alliance (IDRA), and creating lifeguard centered programs that can grow internationally while still addressing local community needs. Drasko Bogdanovic also discussed the Lifeguard Project and the idea of “lifeguards for life,” emphasizing continued collaboration, training, and support for rescuers long after certification.** Support Deep Dive Into Water Safety by contributing to their tip jar: https://tips.pinecast.com/jar/deep-dive-into-water-safety

Deep Dive: An Interview with Ralph Goto
Episode Notes April 26, 2026 From Rescue to Prevention: Ralph Goto on Snorkeling Safety in HawaiʻiUnderstanding the risks behind snorkeling incidents and the future of ocean safety through research, education, and lifeguard leadership This episode explores the evolution of lifeguarding in Hawaiʻi and takes a deep dive into the growing concerns around snorkeling safety. Veteran ocean safety leader Ralph Goto former Chief of the City and County of Honolulu Ocean Safety Division, longtime lifeguard, and one of the key architects of Hawaiʻi’s modern ocean safety system shares how lifeguarding has transformed from informal “beach boy” roots into a professional, prevention-focused first responder model. His career spans frontline rescue work, department leadership, national recognition, and ongoing involvement in the Hawaiʻi Snorkel Safety Study, giving him a uniquely comprehensive perspective on both operations and prevention. The conversation centers on snorkeling, now identified as one of the leading activities associated with rescues and fatalities among visitors. The Hawaiʻi Snorkel Safety Study is discussed in depth, examining possible contributing factors such as traveler fatigue, underlying cardiac or pulmonary conditions, equipment resistance, and emerging concerns like rapid onset pulmonary edema (ROPE). While investigations have included medical examiner reviews and equipment testing including analysis of over 100 snorkels the findings remain largely descriptive and inconclusive, highlighting the need for more rigorous, data-driven research. The episode also addresses concerns about full-face snorkel masks, emphasizing the need for standards, proper fit, and clearer labeling. The discussion calls for shared responsibility across lifeguards, EMTs, fire responders, and the visitor industry, along with stronger collaboration to improve both prevention and response. Proposed next steps include controlled studies, pilot programs at high-risk locations, and improved incident tracking through systems like Watchtower. Beyond research, the episode highlights the importance of prevention through education and community action. Programs led by Duane DeSoto at Nakamakai and others are helping fill gaps where statewide systems have been slow to act. International research, including work by Mike Tipton, supports the growing push to bring water safety education into schools and everyday decision-making for both residents and visitors. The episode closes with a clear message: drowning prevention in Hawaiʻi and globally requires a coordinated, systems-based approach that combines professional lifeguard services, better data, stronger education, and practical, on-the-ground messaging. For visitors, the guidance is simple but critical: choose guarded beaches, ask questions, and respect the ocean.** Support Deep Dive Into Water Safety by contributing to their tip jar: https://tips.pinecast.com/jar/deep-dive-into-water-safety

Deep Dive: An Interview with Mark Haimona
Episode Notes May 5, 2026 Kia Maanu, Kia Ora! Stay Afloat, Stay Alive ! Mark Haimona is a leading Māori water safety educator and researcher from Aotearoa New Zealand whose work has helped reshape Indigenous drowning-prevention strategies through culturally grounded education and community engagement. His career has focused on moving beyond traditional Western lifeguarding models toward approaches that connect directly with communities, culture, and environment. His work has had strong influence internationally, including in Hawaiʻi, where Native Hawaiian watermen, researchers, and educators have looked to Māori-led models for guidance in developing culturally relevant prevention strategies. Mark’s philosophy and outreach methods helped influence the thinking of Hawaiʻi water safety advocates, including work connected to John “Kalei” Clark and broader Native Hawaiian waterman traditions that emphasize environmental knowledge, ocean awareness, and intergenerational teaching. A central theme of the discussion was that effective drowning prevention must be culturally grounded. Mark emphasized that Westernized, one-size-fits-all approaches often fail to reach Indigenous communities. Instead, successful strategies are developed “by the people, for the people.” Face-to-face engagement kanohi ki te kanohi was highlighted as essential for building trust and delivering meaningful education. Communities respond more strongly when they understand who is delivering the message and the cultural connection behind it. The discussion closely paralleled Native Hawaiian ocean knowledge traditions practiced by generations of Hawaiʻi watermen, where reading currents, weather, waves, reefs, and ocean conditions is considered just as important as swimming ability itself. A key message was that many drownings occur not because people cannot swim, but because they lack awareness, preparation, or connection to the environment around them. Strong parallels were identified between Māori communities and Native Hawaiian communities, particularly in the areas of ocean knowledge, intergenerational teaching, and culturally rooted water safety practices. These lessons can be reinforced in the Hawaiʻi’s 2025 Water Safety Plan and the need to prioritize youth-focused education and community-driven prevention efforts. The conversation reinforced that drowning prevention should be approached as a public health issue requiring collaboration, cultural respect, and continued international exchange between Aotearoa New Zealand and Hawaiʻi. ** Support Deep Dive Into Water Safety by contributing to their tip jar: https://tips.pinecast.com/jar/deep-dive-into-water-safety
