Licensing of Chlorine Gas Infusion Applicators in Florida1

Frederick M. Fishel2

This document explains the licensing and regulation of persons who use a portable infusion system to treat water with chlorine gas in Florida as regulated by the Florida Pesticide Law (Chapter 487) and administered by the Florida Department of Agriculture and Consumer Services.

Chlorine Gas Infusion

All persons who use or supervise the use of chlorine gas to treat water in residential swimming pools by means of a portable system must have a pesticide applicator license issued by the Bureau of Licensing and Enforcement/Pesticide Certification Section. Persons licensed in this category are authorized to use only those chlorine gas products specifically registered by the EPA and FDACS with label directions for application to residential swimming pools. Individuals who conduct or supervise water treatment using machinery permanently attached to all pools are exempt from this licensure requirement. This category is valid for licensure of commercial applicators. The Chlorine Gas Infusion category is regulated by the Florida Pesticide Law (Florida Statutes, Chapter 487).

Category Certification Standards

Applicators seeking a license in this category must demonstrate practical knowledge of the safe handling and application of liquefied chlorine gas for treatment of swimming pools, hot tubs, and spas. This will include a knowledge of:

  • the toxicity of liquefied chlorine gas;

  • the dispersion properties and other characteristics of gaseous chemicals;

  • equipment types;

  • calibration procedures;

  • application techniques;

  • air and water monitoring procedures;

  • use and maintenance of personal protective equipment and clothing; and

  • factors that may lead to a hazardous condition, including handling of pressurized chemicals and direct or continuous exposure to chlorine gas.

License Classification

Certified chlorine gas infusion applicators are licensed as commercial applicators.

  • A commercial applicator licensed in the chlorine gas infusion category is licensed to apply only those chlorine gas products specifically registered by the EPA and FDACS with label directions for application to residential swimming pools. A commercial applicator is usually a contract applicator. The commercial applicator fee for a four-year license is $250.

Examinations

Persons must successfully complete the chlorine gas infusion examination before they can apply to the Department for a license.

The chlorine gas infusion examination is administered by FDACS–Division of Agricultural Environmental Services and select UF/IFAS county Extension offices. The chlorine gas infusion examination may be scheduled by calling the FDACS Pesticide Certification Section at 850-617-7876 or check with your local UF/IFAS extension office for the availability of this exam. No special qualifications must be met to take the examination. There is no fee to take the examinations.

Study Materials

Study materials for the chlorine gas infusion examination may be obtained from the FDACS Pesticide Certification Section by calling 850-617-7876. Sample labels may be obtained from suppliers of chlorine gas infusion products.

Recertification

Applicators must recertify every four years. To recertify, applicators may take the examination again or attend training and obtain 4 continuing education units (CEUs) approved for the chlorine gas infusion category. No substitutions of other types of CEUs are allowed. Opportunities to earn CEUs may be found at http://www.flaes.org/.
