How to Control Spills of Liquid in the Laboratory

Post by Hemn.

The work in the laboratory needs special professionalism and extreme caution, because it’s a very sensitive place, and we are dealing directly with chemical materials. Of course, some of these materials are dangerous and there are risks on the human health, if not dealt with safely and carefully.

Every day with these materials we must be ready for all possibilities. The spilling of a chemical material is one of those possibilities which may happen in the laboratory and if we don’t deal with it by scientific methods and cautions, it could cause a lot of problems.

To control the spills and protect ourselves from its risks, we must remove the residue of those material to limit risks, for this purpose there are several steps that must be done to keep ourselves safe.

Test the PH to know if the spills acidic or basic material.

1-warning the staff of the laboratory.
2-putting blocker around the place of the spill.
3-contacting and consultation with the persons who have good knowledge about laboratory and ask them for help to remove the spill.
4-put on your protective equipment. (Goggles-gloves-lab coat- closed toe shoes).
5-Try to ascertain what the material is, carefully smell it. If we know what it is we can clean up, if we don’t know we must go to practice point 3.
6-Test the PH. (paper pH., pencil pH test)
We must identify which method we should clean up with (Acidic, Neutral and Basic).
If the liquid spill acidic, It must to be neutralized with a weak base like sodium bicarbonate (NaHCO3). After it’s absorbed the liquid spills sweep up the solid and dispose of in the solid waste.

Using sodium bicarbonate to neutralize an acidic liquid spill.

If the liquid spill neutral, dispose of in the solid waste.

9- Basic
If the liquid spill is basic, it must to be neutralized with a weak acid. After dispose of it.
