Spill Cleanup Procedures
Bleach can be poured down the dink by small amounts as long as the bleach is diluted by the running water.
No data/information is available
Absorb spill using an absorbent, noncombustible material such as earth, sand, or vermiculite. Also provide ventilation
Very small quantities of chemicals to protect ones safety during experiments at home.
What are small-scale techniques?

Have an open window or stove exhaust fan to provide proper ventilation
Have accessibility to water nearby (sink, bottled water, or bathroom shower)
Have a first aid kit nearby
Keep sodium bicarbonate (baking soda) on hand to neutralize spilled assets because the concentrated acids can cause serious burns
List 5 precautions that must be taken before beginning an experiment.
sodium bicarbonate (baking soda).
- As indicated in the video, what common substance can be used to neutralize a spilled acid?
