Develop an IAQ management plan for any facility alterations or additions. Address all five categories of IAQ management as defined by SMACNA: 

• HVAC protection means protecting HVAC equipment and ducts from dust and odors during construction. Seal off equipment and ducts with plastic and use MERV 8 temporary filtration if the equipment is used during construction activities.
• Source control includes the specification and proper handling of low-toxicity products such as paints, adhesives, and carpets. Also, avoid introducing fumes and pollutants from equipment or machinery used onsite.
• Pathway interruption means isolating occupied areas from construction activities by using physical barriers or by manipulating pressure differentials within the building so that construction areas are negatively pressurized in comparison to occupied areas.
• Housekeeping means adopting cleaning practices that minimize pollutant transfer into occupied spaces. Typical measures include the use of HEPA filters on vacuums, increased frequency of cleaning activities, and the use of wetting agents before sweeping up dust and debris.
• Scheduling includes coordinating high-pollution activities during off-hours and facilitating the flush-out prior to occupancy.
