Hypersensitivity Pneumonitis (HP)<br />

Methicillin-Resistant Staphylococcus aureus (MRSA)<br />

Mollusum Contagiosum<br />

Plantar warts<br />

Athlete’s foot<br />

Key Points: Emphasize that good pool operating procedures and educating swimmers and<br />

parents are the best ways to prevent accidental contamination before it happens. These include:<br />

Maintain proper disinfectant levels at all times. Drops in levels are an invitation for<br />

bacteria to spread in the pool water.<br />

Have all children use the bathroom before entering the pool. Have designated<br />

changing areas away from the deck or seating area. Swim diapers and rubber pants do<br />

not prevent contamination. They only provide containment for a short period of time.<br />

Require every swimmer to shower before entering the pool. Doing so will remove<br />

contaminated substances that may spread diseases in the pool water. In many states,<br />

this is a regulation.<br />

Prohibit pool use for people with open wounds/sores or known infections. Since<br />

open wounds and sores eliminate the natural barrier that skin provides against disease<br />

transmission, people with open wounds and sores can both transmit and receive<br />

contamination more easily than people without these problems.<br />

Work with local and state health departments.<br />

Other Pool Water Health Concerns<br />

Key Point: Discuss disinfection by-products production and means of controlling them. Include:<br />

How to minimize DBPs. Use of ozone, ultraviolet and chlorine dioxide with chlorine or<br />

bromine.<br />

Give a brief description of Trihalomethanes (THMs) and their production in pool water.<br />

Key Point: Discuss Bromine itch and its two causes and how to minimize its occurrence.<br />

Additional Training: Suggest that students enroll and take the Advanced RWI online training<br />

course from NSPF. Alternatively, offer to teach the classroom version of the course.<br />

Final Questions: Ask the participants if they have any questions pertaining to the lesson they<br />

have just completed. If there are participants who are still having trouble with the concepts of this<br />

lesson, offer additional help during a break or after class.<br />

NOTE: Recommend the RWI online/classroom training course and handbook for additional<br />

training.<br />
