Chemical sensitivity is recognised as a disability for the purposes of the Disability Discrimination Act. The Human Rights and Equal Opportunity Commission’s Access to buildings and services: Guidelines and Information includes a section on chemical sensitivity.
For detailed recommendations see the Indoor Environmental Quality Final Report, which was a project of the National Institute of Building Sciences with funding support from the Architectural and Transportation Barriers Compliance Board (Access Board). These are available at http://ieq.nibs.org/index.php or as a pdf file at http://ieq.nibs.org/ieq_project.pdf
For example:
"Use fragrance-free, low-VOC cleaning products. Do not use fragrance-emitting devices (FEDS), plug-ins, or sprays; urinal or toilet blocks; or other deodorizer/re-odorizer products. Reduce odors by increasing cleaning and ventilation and/or using baking soda or zeolite to absorb odors. Do not use products containing paradichlorobenzene ( 21) or naphthalene, which are common ingredients in FEDS.
Do not use cleaner/disinfectant combination products. Avoid or limit the use of products containing chlorine, ammonia, quaternary ammonium, phenol, isopropyl and other alcohols, formaldehyde, and other petroleum distillates. Do not use citrus- or pine-based products. Hydrogen peroxide-based products are the preferred disinfectants, but still should be used with caution and care. Use hot water for cleaning to reduce the need for soaps, detergents, and disinfectants.
Use disinfectants only in areas and at strengths (i.e., levels of disinfection) required by law. Check with local health department to obtain details of all legal requirements. Clean surfaces thoroughly before disinfecting. Leave disinfectants in place for the correct amount of time before wiping surfaces clean."
Further information on reducing the use of toxic chemicals and so making buildings and public spaces more accessible for people with chemical sensitivities can be found on the following websites. (Note that not all suggestions will be appropriate for everyone or even anyone with chemical sensitivities.)
