What is the fourth principle of odor control, if applicable?

The fourth principle of odor control is sealing or encapsulating the source area. This step is crucial when dealing with persistent odors, particularly in situations where odors are emanating from porous materials or sealed surfaces, such as carpets, wood, or walls. By sealing the source, you effectively trap the odor particles and prevent them from escaping into the environment, thereby mitigating the issue at its root.

Encapsulation involves applying a sealant that locks in odor causers, which is especially effective after the area has been cleaned. This technique not only helps in controlling the odor but also prolongs the life of the materials involved, as it protects them from future contaminations and helps maintain a fresh environment. This method is often utilized after other cleaning and deodorization techniques have been performed, ensuring that any remaining odorous substances are contained.

The effectiveness of this approach hinges on its ability to address the source of odors directly rather than merely masking them or addressing surface level issues, which is why it is identified as a crucial principle in the overall strategy for successful odor control.
