Commodity Fumigation License Practice Exam

The canister with a yellow stripe and an orange stripe is specifically used to indicate protection from hydrogen phosphide. Hydrogen phosphide, commonly known as phosphine, is a fumigant used to control pests in various commodities.

The color-coding system for gas canisters is designed to provide quick visual identification and ensure that workers handle hazardous materials safely. The yellow stripe suggests caution, while the orange stripe typically denotes a substance that requires careful handling due to its toxic nature.

In the context of fumigation, understanding these color codes is crucial for ensuring the safety of personnel and compliance with regulatory requirements. Proper identification helps mitigate the risks associated with exposure to hydrogen phosphide during fumigation operations, making it essential for anyone working in the field to recognize what each color stripe represents.
