Precautions to do experiment
Answers
Explanation:
. No food or drink is allowed in lab unless food or drinks are provided as a part of the lab. Even though lab tables and counters are wiped down before each lab set up, as a result of some laboratory exercises, chemical residues may be present on the tables. For labs exercises involving food or drinks, lab assistants and instructors will follow procedures that allow safe consumption. Smoking is prohibited in all University buildings.
2. Shoes must be worn in lab.
3. If you have very long hair, please tie it back in the laboratory.
4. Handle chemicals, reagents, and stains carefully and follow all warnings. All bottles and containers are labeled as to contents and potential hazards. If, for example, a label says avoid contact with substance and fumes, do so. For potentially hazardous chemicals, information on the hazards, proper handling, and clean-up is provided on Material Safety Data Sheets (MSDS). These are available in the lab. It is highly recommended that you spend the first few minutes of the lab consulting the MSDS.
5. Read all precautions in the laboratory manual and on labels and follow directions exactly.
6. Always double-check the name of the reagent to be used and the name of the reagent you are using. Reagent bottles should remain stoppered, except when you are actually pouring solutions out of them. Always replace the stopper or lid of stock solutions or stains. Be sure to put them on the container they came from.
Take only as much as you need and never return leftover solutions to a reagent bottle. Discard leftovers in the proper container.
7. Do not use your thumb as a stopper. Swirl gently or put a piece of parafilm over the opening to mix solutions.
8. Label all test tubes and other containers with contents.
9. Do not pour reagents and chemicals down the sink. Dispose of these only in designated containers.
10. Put plant remains in the designated containers. Do not discard solids or plant materials down the sinks. They will clog up the sink. Use specified containers for such wastes
