Pesticide: Any substance or mixture of substances intended to prevent, destroy,
repel, or mitigate any pest. For the purposes of this manual, pesticides are
considered either general use or restricted use.

pH (potens hydrogen): The symbol for the negative logarithm of the hydrogen
ion concentration, which is a measure of the degree of acidity or alkalinity of a
solution. Values between 0 and 7 indicate acidity and values between 7 and 14
indicate alkalinity. The value for pure distilled water is 7, which is neutral.

Plumbing fixture: A receptacle or device that
• Is permanently or temporarily connected to the water-distribution system
of the vessel and demands a supply of water from the system; or
• Discharges used water, waste materials, or SEWAGE directly or indirectly
to the drainage system of the vessel.

Plumbing system: The water supply and distribution pipes; PLUMBING
FIXTURES and traps; soil, waste, and vent pipes; sanitary sewer drains and
vessel drains, including their respective connections, devices, and appurtenances
within the vessel; and water-treating EQUIPMENT.

insecticides and rodenticides.
• Substances necessary for the operation and maintenance of the
establishment such as nonfood-grade lubricants and PERSONAL-CARE
ITEMS that may be deleterious to health.
• Substances not necessary for the operation and maintenance of the vessel
and are on the vessel, such as petroleum products and paints.

Pollution: The presence of any foreign substance (organic, inorganic, radiologic,
or biologic) that tends to degrade water quality to create a HEALTH HAZARD.

Portable: A description of EQUIPMENT that is READILY REMOVABLE or
mounted on casters, gliders, or rollers; provided with a mechanical means so that
it can be tilted safely for cleaning; or readily movable by one person.

Potable water: Water that is halogenated and pH controlled and is intended for
• Drinking, washing, bathing, or showering;
• Using in fresh water SWIMMING POOLS and WHIRLPOOL SPAS;
