What does a TC-84A respirator have?

1. A particulate filter

2. A chemical cartridge only

3. A combination chemical cartridge and particulate filter

4. None of the above

The correct answer is: A combination chemical cartridge and particulate filter

A TC-84A respirator is specifically designed to provide respiratory protection against both particulate matter and certain chemicals. It features a combination of a chemical cartridge and a particulate filter, which allows the user to be protected from a wider range of airborne contaminants. The integration of both components means that while the particulate filter captures physical particles like dust and biological agents, the chemical cartridge absorbs harmful gases and vapors. This combination is particularly useful in environments where both types of hazards may be present, enhancing safety and effectiveness during use. In contrast, options focusing solely on a particulate filter or a chemical cartridge lack the combined functionality that the TC-84A respirator offers. This distinction is crucial for ensuring adequate protection in various situations where exposure to both particulates and chemical hazards is a concern. Therefore, understanding the purpose and components of the TC-84A respirator highlights its comprehensive protective capability.
