What is a common consequence of inadequate ventilation in a confined space?

  1. Increased productivity

  2. Enhanced safety

  3. Presence of dangerous gases

  4. Improved air quality

The correct answer is: Presence of dangerous gases

Inadequate ventilation in a confined space can lead to the accumulation of dangerous gases, making it a significant safety hazard. Without proper airflow, harmful substances can build up, such as carbon dioxide, carbon monoxide, or other toxic fumes resulting from operations occurring within that space. This creates an unsafe environment for workers, as these gases can lead to serious health issues or even fatal accidents. In contrast, the options related to increased productivity, enhanced safety, and improved air quality would not hold true in situations characterized by poor ventilation. Instead, these conditions typically result in detrimental effects on both health and workplace efficiency.
