Indoor Air Quality (IAQ)Developing a Management Plan Roger G. Morse AIA Dyanki, Inc.
Do Nothing Until Problem Arises • Very expensive • Facility shutdowns • Employee lost time • Disability and worker compensation claims • Increased absenteeism • Decreased productivity • Poor employee moral
Indoor Environmental Quality (IEQ) • Indoor Air Quality (IAQ) • Lighting • Noise • Ergonomics • Safety • Stress in the workplace
Operation of an IEQ Management Program • Solve Obvious Problems • Empower building occupants to report IAQ Concerns • Set up a management system to make sure reports get to someone who takes action
Reports of IAQ Concerns • May be early warning of a serious problem, • Could be result of an allergic reaction in one individual, • May be a baseless complaint.
Responding to Reports of IAQ Concerns • All reports must be taken seriously. • Deal with reports in a uniform manner. • Use a tiered approach that brings more assets to bear as necessary.
First Tier Review • Medical Review • Health and Safety Walk Through • Facilities Walk Through • Recommendations
First Tier Review • Medical Review: • document any symptoms experienced by the employee(s). • evaluate the potential for the symptoms to be caused by indoor air quality.
First Tier Review • Health and Safety Walk Through: • Observe conditions, • Gather additional information, • Determine the extent of the problem, • Look for other problems (poor lighting, improper ergonomics, workplace stress).
First Tier Review • Facilities Walk Through: • Look for evident problems, • Document conditions in the space, • Initial evaluation of the HVAC system.
Second Tier Investigation • If the First Tier Review does not resolve the issue then additional investigation is necessary. • Second tier at a level that can normally be accomplished by facility personnel using checklists.
Second Tier Investigation • Health and Safety: • Perform a survey to locate potential pollution sources. • Prepare an inventory of chemicals used in the space. • Provide the employee reporting the concern with a diary to log the times and locations of the occurrence.
Second Tier Investigation • Facilities: • Survey the facility for building or system problems (e.g. leaking roofs, poor housekeeping, faulty or leaking plumbing). • Perform an HVAC evaluation.
Third Tier Investigation • Data is collected on conditions in the building. • If the facility management has the resources internal personnel can perform this work. • May require outside consultant.
Third Tier Investigation • Health and Safety: • Measure for specific potential chemical contaminants. • Inspect for microbiological growth and remove if found. • Correct conditions that allowed mold amplification. • Air sampling for bioaerosols is not generally recommended.
Third Tier Investigation • Facilities: • Log temperature and humidity (ASHRAE 55) • Log carbon dioxide levels for one week, • Measure carbon dioxide in various locations within the problem area, • Measure ventilation air (ASHRAE 62)
Fourth Tier Investigation • Resolution not found. • Corrective work does not pass a 60-day evaluation. • Outside consultant. • Procure IAQ investigation and design services with an annual contract for services.
Administrative Requirements of an IEQ Management Program Setting up a Program
IEQ Management Program • Policy and Organization • Program Administration • Documentation • Training • Communications • Audit and Review
IEQ Management Program • Policy and Organization • formal decision at the topmost level • specific administrative position • responsibility and authority • effective control over activities that could impact on IEQ • head of buildings and grounds
IEQ Management Program • Program Administration • use existing management systems • simpler to add to or slightly modify existing controls than to invent and administer entirely new ones
IEQ Management Program • Documentation • Program Operation • Program Effectiveness • Inventory • Compliance with Regulations and Standards
IEQ Management Program • Training • sufficient to perform initial inspections • appropriate to level of activity
IEQ Management Program • Communications • occupants informed that they have an affirmative responsibilityand full authority to report IEQ concerns • inform chain of command that they have a responsibility to forward reports • part of job performance evaluation
IEQ Management Program • Audit and Review • be critically evaluated at periodic intervals • success of report response procedures • effectiveness of administrative controls • adequacy of documentation • compliance with current regulations • level of personnel training • equipment condition
