What does proper ventilation help prevent in a workplace with oil-related activities?

Excessive noise levels
Inadequate lighting
Spontaneous fires
Operator fatigue

The correct answer is: Spontaneous fires

Proper ventilation is crucial in environments where oil-related activities take place because it helps to prevent the accumulation of flammable vapors and gases that can lead to spontaneous fires. In such settings, oil and other flammable materials can release vapors that, if allowed to accumulate without adequate ventilation, can reach dangerous concentrations. When these vapors come into contact with an ignition source, they can ignite, resulting in fires or explosions. By ensuring that there is sufficient airflow, proper ventilation dilutes these vapors, thereby reducing the risk of ignition. This is particularly important in workplaces that handle flammable substances, as the consequences of fire can be severe, encompassing loss of property, injury, and potential loss of life. Therefore, maintaining proper ventilation is a key safety measure that directly impacts fire prevention in workplaces involving oil and similar materials.
