isolation include:
    * Isolate workers from chemicals
          + use of closed systems such as those used during the processing and transfer of flammable liquids in petroleum refineries, or the use of glove boxes or glove bags
          + placing a process, or a part of it, within an enclosure which may also be fitted with exhaust extraction to remove contaminants
          + isolating operations in one room with access restricted to properly protected personnel
          + placing operators in a positive pressure cabin that prevents airborne contaminants entering
          + distancing workers from hazardous chemicals and any potential hazards generated by their use.
    * Isolate chemicals from other chemicals
  Hazardous chemicals should be physically separated from any chemicals or other things that may be incompatible. This is achieved by distance, barriers, or a combination of both barriers and distance.
  Isolation as a control measure is usually used to control physicochemical risks (for hazardous chemicals that are dangerous goods) because of the greater consequences when incompatible materials interact. However it is also important to consider isolation for other hazardous chemicals.  The choice of isolation measure used will depend on a range of factors, including:
       * the quantity of hazardous chemicals stored and handled in the work area
       * the types of installation involved and the processes applied to the hazardous chemicals in the work area and their associated hazards
       * all other activities in the work area which may increase the risks
       * any other control measures in place that will minimise the risks.
  If possible, separation distances should be applied in a way that would not require additional control measures. If this is not possible, barriers may be required.
  When choosing to use a barrier, you should consider:
       * the effect that climatic elements may have on a barrier and its effectiveness
       * the level of fire resistance provided by the barrier
       * the structural capability which may be required to withstand weather, and overpressure resulting from internal or external incidents.
When storing chemicals on shelving or other storage systems, hazardous chemicals should not be stored above or below other chemicals or other things which may be incompatible, potentially interact or contaminate.  Hazardous chemicals should never be stored where they could contaminate food, food packaging and other items like personal use products, cosmetics, cigarettes, medication and toiletries.

Engineering controls
Engineering controls are physical in nature, including mechanical devices or processes that eliminate or minimise the generation of chemicals, suppress or contain chemicals, or limit the area of contamination in the event of spills and leaks. They often involve partial enclosure, use of exhaust ventilation or automation of processes. Examples of engineering controls include:
    * using intrinsically safe electrical equipment in hazardous areas
    * using
