When evaluating a pump for removal operations, which TWO aspects must be considered?

When evaluating a pump for removal operations, focusing on ignition source and chemical compatibility is crucial. This is because the environment where the pump is to be utilized may involve hazardous materials that can pose fire or explosion risks. Understanding the ignition source helps in ensuring that the pump will not create sparks or heat that could ignite flammable substances.

Chemical compatibility is equally vital, as different materials used in pump construction can react negatively with the hazardous materials being handled. If the pump materials are not compatible with the chemicals it will encounter, it risks degradation or failure, leading to leaks or spills, which can be hazardous both to personnel and the environment.

While flow rate and nozzle size, temperature and pressure ratings, and maintenance history and manufacturer are essential factors in pump selection, they do not directly address the immediate risks associated with handling hazardous materials. Ignition source and chemical compatibility specifically address safety and operational integrity, which are of paramount importance in hazardous material removal operations.
