Divers, dive operators and dive professionals must continue to practice good hygiene and disinfection of scuba equipment during the COVID-19 pandemic. Disinfectant products kill microorganisms. When discharged into the environment, they can continue to kill or cause harm until they break down. Disinfecting scuba equipment that contacts the eyes, nose and mouth should be routine for all dive operators. Know the composition of the products you use, and be aware of the potential impacts of disposal.
