Explanation:

1. Laboratory PPE is non - negotiable as it protects against chemical splashes, fumes, and physical hazards. Chemicals can cause burns, inhalation problems, etc.
2. If a corrosive chemical spills on skin, immediately rinse with large amounts of water to dilute and remove the chemical, reducing damage.
3. Food and drinks are prohibited because organic solvents and volatile chemicals can contaminate them, leading to ingestion of harmful substances.
4. Before using a fire extinguisher in case of a small laboratory fire, ensure you are safe, identify the type of fire (e.g., Class A, B, C), and choose the appropriate extinguisher.
5. Accurate reporting of accidents or near - misses is essential in laboratory work to prevent future incidents, identify safety issues, and ensure compliance with safety regulations.
