EBC Seminar The IAQ/Mold Assessment – Getting it Right! – Controlling Your Risk First Speaker Nancy A. Comeau Massachusetts Division of Occupational Safety

IAQ Issues-A Regulatory Perspective Nancy A. Comeau CIH Occupational Hygiene/Indoor Air Quality Program Supervisor Massachusetts Division of Occupational Safety (DOS)

Goal of this talk Explain who the Division of Occupational Safety is and what authority we have in IAQ arena Explain who the Division of Occupational Safety is and what authority we have in IAQ arena Explain what standards/regulations we generally reference Explain what standards/regulations we generally reference Provide some information about standards/guidance documents/ certifications in IAQ field Provide some information about standards/guidance documents/ certifications in IAQ field

Big Questions Big Questions Which agencies deal with indoor air quality in Massachusetts Which agencies deal with indoor air quality in Massachusetts Is there a difference between public and private sector workers in Massachusetts Is there a difference between public and private sector workers in Massachusetts

Private versus Public Sector Workplaces Private sector workplaces in the US are covered by Federal OSHA Standards. Private sector workplaces in the US are covered by Federal OSHA Standards. Public sector workplaces are not specifically covered by OSHA Standards in Massachusetts Public sector workplaces are not specifically covered by OSHA Standards in Massachusetts

Massachusetts Ma General Law Chapter 149 Section 6 gives DOS the authority to make reasonable rules, regulations and orders for the prevention of accidents and occupational diseases Ma General Law Chapter 149 Section 6 gives DOS the authority to make reasonable rules, regulations and orders for the prevention of accidents and occupational diseases

Massachusetts There is not currently an OSHA Standard for indoor air quality so DOS will investigate IAQ in the private sector using Chapter 149 section 6 (OSHA pre-empts DOS where there are existing standards) There is not currently an OSHA Standard for indoor air quality so DOS will investigate IAQ in the private sector using Chapter 149 section 6 (OSHA pre-empts DOS where there are existing standards) Chapter 149 section 6 also covers municipal and county workplaces however, it does NOT cover State workplaces Chapter 149 section 6 also covers municipal and county workplaces however, it does NOT cover State workplaces Dos still investigates State workplaces on request or complaint noting in report that it is the Personnel Administrator who has authority for State employee health and safety Dos still investigates State workplaces on request or complaint noting in report that it is the Personnel Administrator who has authority for State employee health and safety

Carbon Monoxide OSHA Standard is 50 ppm over 8 hour day-way too high for general indoor air quality standard OSHA Standard is 50 ppm over 8 hour day-way too high for general indoor air quality standard DOS uses EPA National Ambient Air Quality Standard (NAAQS) standard of 3 ppm over ambient outside levels as indicator of source of CO or no more than 9 ppm for 8 hour day DOS uses EPA National Ambient Air Quality Standard (NAAQS) standard of 3 ppm over ambient outside levels as indicator of source of CO or no more than 9 ppm for 8 hour day

Carbon Dioxide Only used as INDICATOR of adequate ventilation (Must test in normally occupied space) Only used as INDICATOR of adequate ventilation (Must test in normally occupied space) DOS Recommendations DOS Recommendations Less than 800 ppm-considered to be adequate ventilationLess than 800 ppm-considered to be adequate ventilation 800-1000 ppm considered marginal ventilation800-1000 ppm considered marginal ventilation ASHRAE 62 –700 ppm above background outside (typically 300) ASHRAE 62 –700 ppm above background outside (typically 300)

Ventilation State Building Codes drive ventilation requirements State Building Codes drive ventilation requirements Ventilation is expected to meet the building code that was in existence at the time the facility was built or significantly renovated Ventilation is expected to meet the building code that was in existence at the time the facility was built or significantly renovated While building codes may change over the years, facility generally does not have to upgrade to new code until renovated While building codes may change over the years, facility generally does not have to upgrade to new code until renovated Natural ventilation (openable windows) allowed Natural ventilation (openable windows) allowed

Ventilation Standards Building Codes-In Massachusetts now in 6 th edition of building code. 6 th edition in effect since 1997-adopted the BOCA mechanical code for ventilation requirements in SPECIFIC settings Building Codes-In Massachusetts now in 6 th edition of building code. 6 th edition in effect since 1997-adopted the BOCA mechanical code for ventilation requirements in SPECIFIC settings Ex-Bowling alleys- 25 cfm outdoor air per personEx-Bowling alleys- 25 cfm outdoor air per person -Auditoriums-15 cfm outdoor air per person -Auditoriums-15 cfm outdoor air per person ASHRAE Standard 62 Ventilation for Acceptable Indoor Air Quality-(may be incorporated as parts of some building codes) ASHRAE Standard 62 Ventilation for Acceptable Indoor Air Quality-(may be incorporated as parts of some building codes) Building codes may be at local level as well Building codes may be at local level as well
