Fire protection licensing in Oklahoma
Oklahoma licenses fire protection work through two state agencies. The Department of Labor's Alarm, Locksmith and Fire Sprinkler program licenses fire alarm and fire sprinkler companies, managers, technicians and sprinkler inspectors by state exam at CareerTech centers. NICET Water-Based Systems Layout Level III or IV qualifies a sprinkler manager, and NICET Level III in water-based systems may replace the sprinkler technician exam. The State Fire Marshal licenses extinguisher and suppression work: ICC-NAFED certification is required for portable, pre-engineered kitchen and pre-engineered industrial work, and NICET Special Hazards Level I, II or III for engineered systems, plus a state rules exam.
