Cleaning for Asthma-Safe Schools (CLASS)

Background and Purpose

One in five Californians spends his or her image of a bucket and rubber glovesday in school, increasing the stakes for addressing asthma in the school setting.  Custodians have high rates of work-related asthma, while 15% of the state’s children have been diagnosed with the disease.

Cleaning products are used in schools and other workplaces.  They can cause or worsen asthma and release unsafe chemicals into the air.  The Work-Related Asthma Prevention Program (WRAPP) developed the Cleaning for Asthma-Safe Schools (CLASS) project to assist California schools in adopting safer cleaning methods that help protect workers and students from asthma.  WRAPP is housed in the Occupational Health Branch. 


  • Promoting school guidelines for asthma-safe cleaning;
  • Partnering with California school districts to provide technical support for switching to safer cleaning products and practices;
  • Creating and distributing educational materials about safer cleaning methods and products; and
  • Raising awareness about the importance of asthma-safe cleaning via newsletter articles, webinars, and presentations.
