Answer:
Some of the safety measures one can take to prevent damage to the microscope, microscope slide or living specimen include;
1. Always carry the microscope with two hands
2. Do not touch the microscope lens
3. Clean and store properly after using
Explanation:
1. Microscopes are delicate laboratory equipments and hence, should be handled with care. The proper way to handle or carry a microscope is to place one hand on the arm and the other below the base of the microscope. This will prevent the microscope from hitting something and getting damaged or something falling off.
2. The lens, either the objective or occular, is what makes visibility of any specimen possible. It shouldn't be mishandled by touching it or using inappropriate materials to clean it. A lens cleanser designed for that function should be used.
3. After use, the microscope should be cleaned thoroughly and stored in a dry place. The maintenance of the microscope will improve how long it will last.
