Question

Write the laboratory precautions lab activity

Answer 1

Answer:

LAB SAFETY

1. 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
