Fire Extinguisher 1-3 (OSFMFEI21) The OSFMFEI21 spans three progressive levels, each building technical depth through scenario-based assessments and hands-on practical components. Level 1 covers agent types and discharge mechanics; Level 2 introduces complex fire classifications and containment strategies; Level 3 demands expertise in industrial systems and emergency decision-making under pressure. This tiered structure ensures competency development rather than single-attempt memorization.
