Describe the hazardous procedures using the primary characteristics to quantify these procedures including: frequency of use (how often is the hazardous material used?); duration of use (what interval of time is the hazardous material used?); toxicity (none, low to high, or an immediate hazard to life and health); volume of effluent or emissions (how much effluent or emissions are given off in the lab process?); characteristics of the effluent (is the effluent a gas, fume, mist, a particulate or powder?); possible conditions to implement variable exhaust air strategies (not occupied in front of containment device, process not active or standby with containment device, sash or containment device door closed)
