What should be used to remove vapors from a tank during the purging process?

The use of a bonded educator type air mover during the purging process is essential for safely and effectively removing vapors from a tank. This equipment is designed to create a low-pressure area that helps to displace and evacuate vapors that may be present inside the tank. It's particularly effective in ensuring that the vapors are safely guided out of the tank and do not pose a risk of combustion or explosion, which is a critical consideration in handling flammable substances.

Additionally, using a bonded educator type air mover ensures that the process complies with safety regulations, as it minimizes the risk of static electricity discharge that could ignite the vapors. The bonded nature of the air mover helps to maintain an electrical connection that prevents static buildup during the operation.

In contrast, other methods such as a high-pressure water system, a manual vacuum pump, or a standard air fan are not designed specifically for vapor removal. They may not adequately handle the vapor concentration safely, potentially leading to hazards. For example, a high-pressure water system can introduce water into the tank, which may cause contamination or reaction with the contents. A manual vacuum pump may not have the efficiency or capability to handle vapors effectively, and a standard air fan could merely circulate the vapors without properly removing
