Which statements are correct regarding hoses used in application equipment?

Hoses used in application equipment must be resistant to the chemicals they come into contact with. This is crucial because many chemical substances can degrade certain materials, leading to leaks, hose failures, or contamination of the environment. When choosing hoses, it is essential to select those that are specifically designed to withstand the chemical properties of the pesticides or herbicides being applied. This resistance ensures the safety and effectiveness of pest control applications and minimizes the risk of harm to the applicator, bystanders, and the environment.

The other statements fail to encompass the comprehensive requirements for hoses. For instance, while it is beneficial for hoses to be made of one material, it is not a strict requirement; many high-quality hoses incorporate multiple materials for enhanced durability and flexibility. Regarding leaking due to inconsistent pressure, while this can be a factor, it is more vital that the hoses are suited for the specific chemicals to prevent leaks at any pressure level. Lastly, durability should be considered for the entire hose, including both the inner and outer layers, since both contribute to the overall integrity and performance of the hose in different conditions.
