Posted September 13, 2012 ACGIH® Presents Engineering Controls, Monitoring and Troubleshooting Techniques For Industrial Ventilation Systems Webinar – December 12, 2012      Industrial ventilation is the first line of defense against airborne hazards in the workplace. Underperforming systems will reduce that level of protection. Smart monitoring techniques will reduce the maintenance time and maintain a high degree of system performance. This webinar will teach methods for testing, monitoring, and troubleshooting problems with industrial ventilation systems (IVS). Topics include: baseline system performance measurement; inferring design information for undocumented systems, monitoring techniques, and troubleshooting methods.
