Indoor Air Quality checklist

The professional inspection solution

You can conduct this checklist for free on the Checkbuster platform. You can use a lap-top, PC or the free inspection App

General

  • Someone is designated to develop and implement an indoor air quality management plan for your company.
  • Your district does have an indoor air quality management plan that includes steps for preventing and resolving indoor air quality problems.
  • Your school district has been tested for radon, and have radon-mitigation systems installed where needed.
  • Your school district does use integrated pest management principles in all areas.
  • Spot-treatment of pesticides is used to control infested areas.
  • All pesticide applicators are trained in the safe use of pesticides.
  • Painted surfaces in your district have been tested for lead-based paint, and has a lead control or removal program been implemented.
  • School buildings have inspected once or twice each year for conditions that may lead to indoor air quality problems.
  • A preventive maintenance schedule is established and in operation for the heating, ventilation, and air conditioning (HVAC) system? Is the schedule in accordance with the manufacturer’s recommendations or accepted practice for the HVAC system.
  • The HVAC preventive maintenance schedule does include the following: checking and/or changing air filters and belts, lubricating equipment parts, checking the motors, and confirming that all equipment is in operating order.
  • Damaged or inoperable components of the HVAC system are replaced or repaired as appropriate.
  • Reservoirs or parts of the HVAC system with standing water are checked visually for microbial growth.
  • Water leaks that could promote growth of biologic agents are promptly repaired.
  • Damp or wet materials that could promote growth of biologic agents are promptly dried, replaced, removed, or cleaned.
  • Microbial contaminants are removed from ductwork, humidifiers, other HVAC and building system components, and from building surfaces such as carpeting and ceiling tiles when found during regular or emergency maintenance activities or visual inspection.
  • General or local exhaust ventilation is used where housekeeping and maintenance activities could reasonably be expected to result in exposure to hazardous substances above applicable exposure limits.
  • When point sources generate airborne concentrations of contaminants above applicable limits, local exhaust ventilation or substitution are used to reduce the exposure concentrations to below the limits.
  • When the carbon dioxide level exceeds 1,000 parts per million, the HVAC system is checked and repaired as necessary to ensure the system is operating properly.
  • When the temperature is outside of the range of 68 to 79ºF, the HVAC system is checked and repaired as necessary to ensure the system is operating properly.
  • Humidity levels are maintained between 30% to 60% relative humidity.
  • When a contaminant is identified in the make-up air supply, the source of the contaminant is eliminated, or are the make-up inlets or exhaust air outlets relocated to avoid entry of the contaminant into the air system.
  • If buildings do not have mechanical ventilation, are windows, doors, vents, stacks, and other portals used for natural ventilation operating properly.
  • Complaints are promptly investigated that may involve a building-related illness.

Smoking

  • Smoking in school buildings is prohibited except as part of a classroom instruction or a theatrical production.
  • Written district board of education policies and procedures do prohibit smoking in school buildings.

Renovations and Remodeling

  • During renovation work or new construction, local ventilation or other protective devices are used to safeguard employees and students from dust, stones, other small particles, and toxic gases, which may be harmful in certain quantities.
  • Renovation areas in occupied buildings are isolated so that dust and debris is confined to the renovation or construction area.
  • Precautions are implemented in case lead-based paint is disturbed during renovation or new construction.
  • When renovating or during new construction, product labels are checked, or information is obtained on whether paints, adhesives, sealants, solvents, insulation, particle board, plywood, floor coverings, carpet backing, textiles or other materials contain volatile organic compounds that could be emitted during regular use.
  • The information referred to in Question 29 is used to select products and to determine necessary measures to be taken to comply with indoor air quality regulations.
  • Employees are notified at least 24 hours in advance, or promptly in emergency situations, of work to be performed on the building that may introduce air contaminants into their work area.

Recordkeeping

  • The maintenance schedule is updated to show all maintenance performed on the building systems.
  • The maintenance schedule does include the dates that the building systems maintenance was performed and the names of the persons or companies performing the work.
  • Maintenance schedules are retained for at least three years.
