What should we do to reduce the risk when working with concentrated acids and bases
Solnce55 [7]

What should be done to reduce the risk when working with concentrated acids and bases are;

<em><u>1) Ensure that the concentrated acids and bases are stored separately in safety cabinets. </u></em>

<em><u>2) If you don't have separate safety cabinets and the must be stored in same cabinet, then you must ensure that they are stored in separate compartments. </u></em>

<em><u>3) Lastly, the separate compartments or cabinets must have their separate spill containment compounds.</u></em>

          When working with strong acids and bases during neutralization reactions, usually the production of gases can make the solution which is corrosive to splash and get to people around there.

         Due to how strong the acids and base are, these splashes from the neutralized solution could have potentially damaging effects on humans when it contacts them by either casing skin burns or even blindness.  

Now, to reduce the risk of the adverse effects stated above, what could be done is;

1) Ensure that the concentrated acids and bases are stored separately in safety cabinets.

2) If you don't have separate safety cabinets and the must be stored in same cabinet, then you must ensure that they are stored in separate compartments.

3) Lastly, the separate compartments or cabinets must have their separate spill containment compounds.
