Fire, Smoke, Fire/Smoke & Radiation Damper Inspection:

• Locate and identify all LSS dampers in the facility.  Dampers are given a unique identity which summarizes the specific system (duct type and HVAC equipment), location (floor, room number), and model characteristics of that particular device.  
• Dampers have their location precisely indicated on the mechanical drawings.  The damper identity tag on the print will correspond with the identity label affixed to the device. 
  
• Damper blades and curtains are actuated to test for full closure.  Electric and pneumatic devices manually activated independent of the alarm/control systems.  Pneumatic dampers are isolated during testing to prevent pressurization loss to the system on which it is installed.
• Fusible links are replaced if they are faulty.
  
• Dry lubricant, which prevents the accumulation of dust and debris, is applied to all moving parts. 
  

• A master schedule of all the devices indicates whether it passed or failed.  The schedule also notes the following information: system served, room, size, sleeve length, model, damper type, orientation, link temperature, static/dynamic service, retaining angle, motor type & voltage, and leakage class.
  
• A single page report for each damper is provided which details any damage, faults, or installation errors along with the technician's comments.  This checklist is singed by both the technician which conducted the inspection as well the project supervisor. 
• Digital pictures are taken of each damper.  This provides a photographic record which our client may submit to inspectors, fire marshals, insurance underwriters, and other regulatory agencies.  
• A summary report gives an overview of inspection and testing project.  Copies of the technicians' certifications are provided.
• Mechanical drawings are updated to indicate the identity and location of each damper.  If the facility drawing records are incomplete, Stewart Environmental can provide new 2D or 3D CAD drawings of the HVAC systems.
