Which type of ventilation is typically used to control temperature in a lab environment?

General ventilation is the correct choice for controlling temperature in a lab environment because it is designed to circulate air throughout a space to maintain a comfortable and consistent temperature. This type of ventilation allows for the removal of stale air and the introduction of fresh air, helping to regulate the overall climate of the laboratory.

In a laboratory, maintaining an appropriate temperature is crucial not only for the comfort of personnel but also for ensuring the integrity of experiments and storage of sensitive materials. General ventilation systems can include a combination of mechanical systems like fans and air handling units, which work together to provide the necessary airflow throughout the space.

The other types of ventilation mentioned serve different specific purposes. Local ventilation is typically used to control the exposure to contaminants at the source, such as fume hoods, while exhaust ventilation focuses on removing specific contaminants from the air. Convection ventilation relies more on the natural movement of warm air rising and cool air flowing in, which may not be as effective in a controlled laboratory setting. Thus, general ventilation is the most suitable option for temperature control in a lab environment.
