Better Ways to Clean: Employers should note recent advances in safe cleaning practices and the availability of modern cleaning equipment that minimizes the use of chemicals. Practices and equipment to consider include: (1) Walk-off mats placed inside and outside of entryways (to prevent dirt from being tracked into the building); (2) Microfiber mops, cloths and dusters; (3) High-filtration HEPA vacuums; (4) Walk-behind hard floor auto-scrubbers; (5) Hands-free mops; and (6) Chemical-free cleaning systems. Building owners and planners should take building cleaning into consideration when designing new buildings, remodeling old buildings and choosing materials, such as flooring. See NIOSH's Prevention through Design (PtD) program (http://www.cdc.gov/niosh/topics/PtD) and EPA's Design for the Environment (DfE) (http://www.epa. gov/dfe) for more information.
