Explanation:

It is very important that people inside the laboratory observe all the necessary precautions that are given and required for their own safety, the safety of people around them and the proper maintenance of the equipments in the laboratory.

For Maribel, the proper way for her to arrange the items with her is to keep all her personal items such as her lunch bag and back pack off the table because her lunch bag contains food which would be exposed and prone to contamination in the laboratory.

It is also important that only laboratory materials should be found on the lab table and they should be placed neatly away from the edge of the table in order to prevent them from falling to the ground and breaking. Some Laboratory materials and equipment are made up of glass , while some could contain chemicals or microorganisms and if they should fall to the ground and break, it could lead to glass shards on the floor or microbial or chemical contamination of the laboratory and this would be very harmful to Maribel's health as well as those around her.
