NICET Special Hazards Level I case studies
NICET Special Hazards Level I · Put your knowledge to work in context.
Special Hazards Systems is one of the certification programs listed by NICET, the National Institute for Certification in Engineering Technologies, alongside Fire Alarm Systems, Water-Based Systems Layout, Inspection and Testing of Water-Based Systems, and In-Building Public Safety Communications. It sits within NICET's Fire Protection/Building Systems grouping, which tells you the intended audience: technicians, designers, installers, and inspectors whose work involves hazard-specific suppression and detection rather than the standard water-based or fire alarm tracks. The NICET Special Hazards Level I case studies are 5 cases and about 3,079 words.
