Why might applicators choose not to use certain substances like methyl chloride?

Applicators might choose not to use substances like methyl chloride primarily because it is considered too hazardous for most applications. Methyl chloride is recognized for its potential health risks, including being a carcinogen and causing other serious health problems with exposure. These safety concerns lead to stringent regulations regarding its use, making it less favorable for applicators who prioritize safety for both themselves and the environment.

While some might argue about the strong odor or cost of methyl chloride, these factors do not carry the same weight in the decision-making process as the inherent hazards associated with the substance. Therefore, the overarching concern about safety and regulatory compliance makes this option the most compelling reason for avoiding the use of methyl chloride.
