How to Clean Up a Chemical Spill in the Laboratory

There is a high chance that chemical spills can occur in the laboratory. The first concern before addressing the chemical spill is determining whether there is an injury.

2. Remove any clothing that might have been contaminated by the spill. Wash any part of the body came into contact with the chemical with plenty of water, this includes the eyes. However, you must be sure that the chemical is not reactive with water.

3. Collect information about the chemical before deciding on how to clean up the spill. Critical information about the chemical includes:

Some reaction will emit gas while others will change color. To be sure that the spilled chemical has been neutralized you can use the control compound in excess. After that scoop the material into an impregnable container.
