Presenters: Jonathan Dongell and Jason Eckenrod

Friday, October 14, 1:00 p.m. - 2:00 p.m.
1 Hour | 1 PHTA CEU | 0.1 IACET CEU



This is an important safety concern for all commercial pools, as the current codes and the Health Departments are lacking national minimum requirements for the lightness of the interior finish, and standardized test methods to determine the lightness. This is a critically important safety factor, because a lifeguard needs to identify a person in distress, or at the bottom of a pool, in a timely fashion to prevent drownings. Join us for this session as we review color hues and potential code language update. 


Learning Objectives

  • Review the basics of colorimetry.
  • Examine color finishes.
  • Discuss current code regulations.
