The performance of a laboratory hood was evaluated using ASHRAE standard method at three different ventilation capacity as well as three 110-95 volumetric flow rates of injected SF 6 while a mannequin was located at the front of hood. The environmentally hostile characteristics of SF6 as well as its cost are the major concerns.

SF 6 is extremely hostile to environment and expensive.

The application of ASHRAE hood performance test with smaller volume of tracer sulfur hexafluoride gas is not recommended.
