What type of alteration is suggested when increasing ventilation in an elevator car?

Increasing ventilation in an elevator car typically qualifies as a Minor Alteration Type B. This classification is used because the modification is relatively less extensive than a Major Alteration and does not significantly change the original design or function of the elevator. Minor Alteration Type B specifically applies to changes that primarily involve the upgrade or enhancement of existing systems (such as ventilation), which improve comfort or safety without impacting the overall structural integrity or operational capabilities of the elevator system.

This type of alteration generally requires less extensive planning or approval processes compared to major alterations which might involve a significant change in the structural framework, system capacity, or operational characteristics of the elevator. Other options suggest either larger-scale changes or no alterations at all, which do not align with the intent of simply enhancing ventilation.
