What is required for egress according to NFPA 99?

Egress according to NFPA 99 emphasizes the importance of having clear and accessible paths for exit and emergency evacuation. This requirement is crucial for ensuring that individuals can quickly and safely exit a facility in case of an emergency. Clear pathways are essential to prevent obstructions that could hinder evacuation efforts, allowing for an orderly and efficient response.

Additionally, while identifiable exits with visible signage and adequate corridor widths are also important aspects of a comprehensive egress plan, they fall as secondary elements supporting the primary need for unobstructed exit routes. Emergency lighting is indeed vital, but it's not sufficient on its own without clearly defined and accessible evacuation pathways. Therefore, the requirement focuses primarily on ensuring the paths themselves are available and accessible for all occupants during an emergency.
