What type of cartridges should technicians wear when using dry solvents due to VOCs?

When using dry solvents that contain volatile organic compounds (VOCs), technicians should wear organic vapor cartridges. These cartridges are specifically designed to filter out organic vapors and gases, which are commonly released by various solvents and chemicals.

Organic vapor cartridges contain activated carbon or other adsorbent materials that capture and neutralize harmful vapors, thereby protecting the respiratory system of the technician. VOCs can cause a range of health issues, including headaches, dizziness, and respiratory problems, making it crucial for technicians to have the appropriate protective equipment.

In contrast, particulate filters are mainly effective against solid particles and aerosols, high-efficiency filters are designed for filtering out smaller particulate matter, and dust masks provide minimal protection against vapors or gases. Therefore, using organic vapor cartridges is essential for ensuring safety when working with dry solvents containing VOCs.
