Administrative controls for minimizing exposures to hazardous chemicals include:

  • Substituting in less hazardous chemicals (e.g., using proprietary detergents instead of chromic acid for cleaning glassware; or, using toluene instead of benzene for liquid-liquid extraction or chromatography.)
  • Isolating or enclosing an experiment within a closed system (e.g., glove box, sealed chamber).
  • Micro-scaling the size of the experiment to reduce the amount of chemical usage.
