Hazard Analysis and Critical Control Point (HACCP) plans benefit from DEL Ozone. DEL systems are designed with well-engineered ozone delivery technology, and disinfection potential that has been tested, measured and verified.

HACCP is a management system in which food safety is addressed through the analysis and control of biological, chemical, and physical hazards from raw material production, procurement and handling, to manufacturing, distribution and consumption of the finished product. 





DEL Ozone is fully compliant with OSHA and other applicable workplace standards.

With the Occupational Safety and Health Act of 1970, Congress created the Occupational Safety and Health Administration (OSHA)* to assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance.

About OSHA


DEL Ozone’s ozone systems are compliant with the guidelines set forth by the Model Aquatic Health Code (MAHC), which operates under the Center for Disease Control (CDC).

The Model Aquatic Health Code (MAHC) is a voluntary guidance document based on science and best practices that can help local and state authorities and the aquatics sector make swimming and other water activities healthier and safer. States and localities can use the MAHC to create or update existing pool codes to reduce risk for outbreaks, drowning, and pool-chemical injuries. The MAHC guidelines are all-inclusive and address the design, construction, operation, maintenance, policies, and management of public aquatic facilities.
