Undesirable reflections and glare should be avoided. ° Laboratory furniture should be sturdy. Open spaces between and under benches, cabinets and equipment should be accessible to cleaning. ° Storage space must be adequate to hold supplies for immediate use and thus prevent clutter on bench tops and in aisles. Additional long-term storage space conveniently located within or outside the lab area should also be provided. ° All doors should have vision panels, appropriate fire ratings and preferably be self-closing. ° Facilities for storing outer garments, personal items as well as having tea and lunch and restrooms should be provided outside the laboratory working area. ° Hand-washing basins with running tap water should be provided in each laboratory room, preferably near the exit door. A dependable supply of good quality water is essential.
