Which color cartridge should be used when protecting against organic vapors?

The correct answer identifies the black cartridge as the appropriate choice for protection against organic vapors. Black cartridges are specifically designed to filter out a variety of organic vapors, including those from solvents, paints, and other chemicals that can be harmful when inhaled. These cartridges typically contain activated carbon or other materials that are effective in capturing these types of vapors, enabling safe breathing environments in areas where such hazardous materials are present.

The other options, while relevant to various types of protection, serve different purposes. For example, green cartridges are generally utilized for protecting against certain types of acids and specific toxic gases, while brown cartridges are meant for protecting against certain particulates and metal fumes. Yellow cartridges are typically used for protection against multi-gas situations, but they don’t specifically target organic vapors. Understanding the specific use case for each color cartridge is vital for ensuring the proper safety measures are implemented in hazardous environments.
