What is a necessary feature for rooms with chemical use or storage?

In environments where chemicals are used or stored, separate ventilation systems are crucial for ensuring that any harmful fumes or particulates do not mix with the general air supply of the building. This dedicated approach helps to mitigate health risks for occupants and maintain air quality by preventing contaminants from spreading throughout shared spaces. Proper ventilation through isolated systems also allows for more controlled monitoring and filtering of air specific to areas where chemicals are present, enhancing safety and compliance with health regulations.

While large windows can aid in ventilation, they may not provide adequate airflow or protection against external pollutants. Centralized climate control does not account for the unique ventilation needs of chemical storage, and although double-lock security systems are important for safety and access control, they do not address air quality concerns related to chemical exposure.
