Final answer:
A gas cabinet ventilation system should create a negative pressure to safely contain and vent hazardous gases based on principles such as Boyle's Law.
Step-by-step explanation:
The ventilation system for gas cabinets is designed to maintain a negative pressure relative to the surrounding area. This is crucial for ensuring the safety of the environment and preventing any potential release of hazardous gases into the workplace or surrounding areas. Following the principles of gas laws and ventilation safety, the negative pressure ensures that in the event of a leak, gases are contained within the cabinet and then safely vented away.
For example, applying Boyle's Law, which states that at constant temperature, the volume of a fixed amount of a gas is inversely proportional to its pressure, a well-designed ventilation system will maintain the gas at slightly lower pressure inside the cabinet to keep gases from escaping unnecessarily.
Moreover, it's mandatory to always ventilate and follow manufacturers' instructions when around appliances that could release pollutants into the air, reinforcing the importance of effective cabinet ventilation.
