5.3 Whirlpool Pedicure Foot Tubs and Filters

5.3 Whirlpool Pedicure Foot Tubs and Filters

Outline item I.B.7 tests cleaning and disinfecting whirlpool pedicure foot tubs and filters. Pennsylvania's equipment rule and the step list are different documents. Keep them apart.

What § 7.71b requires

Section 7.71b(a)(3) requires one pedicure basin and stand for a nail technology salon with one nail technician. Subsection (b) says equipment shall increase for each additional technician so each person can work safely and efficiently. The basin sentence does not say whirlpool, screen, filter, jet, pump, or log. It does not publish an after-each-client routine, an end-of-day routine, a weekly bleach flush, or a 10-minute soak. Sections 7.91 through 7.98 do not publish a filter protocol either. They cover a sanitary salon, sanitized contact tools, sterilization of a dropped article, manufacturer directions for a dye, tint, or other chemical, and refusal of a client the licensee believes is infectious.

What CDC documented behind the screen

CDC's nail-hygiene page does not give foot-tub steps. The CDC account of these tubs is the Emerging Infectious Diseases report on California salons.

In 2000, Mycobacterium fortuitum from whirlpool footbaths caused furunculosis: more than 100 customers developed prolonged boils on the lower legs. Investigators recovered that bacterium from all 10 footspas at the salon. Customers who had shaved their legs were at higher risk, and some infected customers had not shaved.

A later survey of 30 whirlpool footbaths in 18 salons found nontuberculous mycobacteria in 29. M. fortuitum was the most common species, in 14 of 30. Investigators removed the filter screen over the recirculation inlet. Twenty-five of 30 tubs had visible debris or slime behind the screen, on the screen, or on the tub surface. Fifteen operators said they had never cleaned behind the screen. Mycobacteria grew whether or not disinfectant was reported and whether or not debris was visible. One tub with no screen and no visible debris still tested positive.

The screen covers the inlet. Skin left there sits in water the pump returns to the next client. CDC's disinfection guideline names biofilms as a factor that blocks disinfectant from the surface underneath. The footbath paper's own words are debris and slime. It does not print a between-client checklist, and it is not a Pennsylvania regulation.

EPA's after-each-client and nightly steps

The between-client and end-of-day distinction is EPA's, from EPA's Recommended Cleaning and Disinfection Procedures for Foot Spa Basins in Salons. It is not a CDC nail-page schedule and not Chapter 7. Any minute count below is EPA guidance.

After each client, once the feet are out of the basin, EPA says:

1. Drain the basin and remove visible debris.
2. Clean the surfaces with soap or detergent, rinse with clean water, and drain.
3. Disinfect with an EPA-registered hospital disinfectant used by the label. Surfaces must stay wet for 10 minutes or the time stated on the label, which may be shorter. For a whirlpool, air-jet, pipe-less, or other circulating spa, fill with clean water, add the disinfectant, and circulate it for the entire contact time.
4. Drain and rinse with clean water.

Nightly, for circulating spas, EPA says:

1. Remove the filter screen, inlet jets, and other removable parts, and clean out debris trapped behind or in them.
2. Scrub those parts with a brush, using soap or disinfectant and following the cleaning directions.
3. Rinse the parts and put them back.
4. Fill the basin, add an EPA-registered hospital disinfectant per the label, and circulate for 10 minutes or the label time if it differs. The pump must run the whole time so piping that holds hidden bacteria is disinfected.
5. Drain, rinse, and air dry.

For a simple basin with no circulation, EPA's nightly steps are drain and remove debris, scrub the bowl with a clean brush and soap or disinfectant, rinse, disinfect for 10 minutes or the label time, then drain, rinse, and air dry. Leaving the screen packed while only the bowl is sprayed skips the step that gets skin out of the recirculation path.

EPA notes that some states require a weekly whirlpool flush with bleach held for over eight hours, and that salons should follow their own state rules. Section 7.71b does not publish that flush, and §§ 7.91 through 7.98 do not either. If a tub has not been cleaned regularly, EPA says ordinary maintenance may not remove bacterial buildup and the manufacturer should be consulted. That is also EPA guidance, not Code text.

Scenario: clear water, dirty screen

The basin water looks clear, so the technician drains it, mists the bowl, and seats the next client with the filter screen still in place. Skin from the last pedicure is packed behind that screen. Clear water does not answer the CDC finding that debris or slime sat behind most screens, or that mycobacteria grew even when debris was not visible. The mist also skips EPA's after-each-client order: drain, remove visible debris, clean with soap or detergent, rinse, then disinfect for the label contact time while circulating the solution in a whirlpool. The screen comes out in the nightly EPA steps, gets scrubbed, and goes back before disinfectant is circulated through the piping. Section 7.71b still requires only the basin and stand. The minutes in the cleaning sequence are EPA guidance, not Chapter 7.
