Define cross-connection and backflow and distinguish between backpressure and backsiphonage.
Identify common examples and risks associated with actual and potential cross-connections.

Module 2: Backflow Prevention Methods and Devices

List the hierarchy of backflow prevention measures: air gaps, RPZs, DCVAs, and vacuum breakers.
Match specific devices to hazard levels and application scenarios, such as hospitals, dishwashers, or sewage plants.

Module 3: Cross-Connection Control Programs

Understand the elements of a cross-connection control program including inspections, device testing, public outreach, and regulatory standards.
Explain the responsibilities of water system personnel in managing cross-connection risks.

Module 4: Safety Regulations and OSHA Compliance

Recognize OSHA’s role in water facility safety and understand the General Duty Clause.
Describe the hierarchy of safety implementation: engineering controls, warning systems, procedures, and PPE.

Identify the required sections and functions of SDS for all facility chemicals.
Demonstrate knowledge of safe chemical handling practices, including acid/base handling and PPE requirements.

Module 6: Confined Space Entry and Atmospheric Monitoring

Define permit-required confined spaces and the roles of entrants, attendants, and supervisors.

Module 7: Fire and Tool Safety

Distinguish between Class A, B, C, and D fires and the appropriate extinguishers for each.
Apply safe practices for hand and power tool use, including guarding and PPE requirements.

Module 8: Lockout/Tagout and Electrical Isolation

List the nine steps of the Lockout/Tagout (LOTO) procedure.
Explain LOTO roles and how to safely isolate and de-energize equipment prior to maintenance.

Module 9: Chlorine, Ozone, and Chemical Safety

Describe the hazards and PPE requirements when working with chlorine and ozone.
Explain safe practices for leak detection, SCBA use, spill response, and ozone room ventilation.

Module 10: UV and LOX System Hazards

Identify safety procedures and equipment for working with UV light systems and mercury vapor lamps.
Understand hazards of Liquid Oxygen (LOX) systems and proper storage, labeling, and ventilation protocols.
