What is a potential hazard of positive ventilation in a space?

Positive ventilation involves introducing fresh air into a space, which aids in maintaining air quality and reducing harmful concentrations of gas. However, one of the major hazards associated with this practice is that it can inadvertently force explosive gases into contained or confined spaces.

By pressurizing an area, positive ventilation may push any flammable or explosive vapors that are present into areas where they can be ignited, leading to potentially dangerous situations. This risk is particularly pronounced in environments where hazardous materials are stored or used, as the movement of these gases brought about by positive ventilation can create a significant threat.

Maintaining awareness of this hazard is crucial for safety, particularly in industries where volatile substances might be encountered. Implementing proper ventilation strategies must be balanced with an understanding of the potential consequences of airflow dynamics within confined areas.
