Professional Understanding for NFPA 20

1. Duration: 36 Training Hours
2. Overview

                           This professional diploma provides an in-depth understanding of the NFPA 20 standard, which governs the selection,         installation, and maintenance of stationary fire pumps. The course integrates theoretical concepts, hands-on case studies,  and practical design workshops to ensure participants become proficient in the application of NFPA 20 for real- world fire protection systems in industrial, commercial, and residential buildings.

4. Prerequisites

• • Basic knowledge of fire protection systems
  • Familiarity with fire alarm and firefighting concepts (NFPA 13, NFPA 14 preferred)
  • Engineering background (mechanical, electrical, safety) or firefighting technician experience

5. Who Should Attend

• • Electrical, Mechanical and Mechatronics Engineers
  • Fire Protection Engineers
  • Safety & Loss Prevention Officers
  • MEP and Firefighting Design Engineers
  • Facility and Maintenance Managers
  • Civil Defense Inspectors
  • NFPA and fire code trainees
