HANDLING CHEMICALS
24. All chemicals in the laboratory are to be considered dangerous. Avoid handling chemicals with fingers. Always use a tweezer. When making an observation, keep at least 1 foot away from the specimen. Do not taste, or smell any chemicals.
25. Check the label on all chemical bottles twice before removing any of the contents. Take only as much chemical as you need.
26. Never return unused chemicals to their original container.
27. Never remove chemicals or other materials from the laboratory area.
HANDLING GLASSWARE AND EQUIPMENT

What is Improvisation in chemistry laboratory?
Improvisation in a chemistry laboratory refers to the ability to think quickly on your feet and adapt to unexpected situations. It involves making creative decisions to address problems or challenges that may arise during experiments. This skill is important for ensuring the smooth progression of experiments and maintaining safety in the laboratory.
Who is responsible to ensure that safety procedures are followed when conducting an experiment?
When conducting an experiment in a laboratory environment, the person conducting the experiment and the Instructor or Principle Investigator are responsible for ensuring that appropriate safety procedures are followed.
What are the Safety precautions observed during electrolysis of brine?
During electrolysis of brine, safety precautions include wearing protective goggles and gloves to prevent contact with the chemicals, ensuring good ventilation as hydrogen gas may be produced, and keeping the electrical setup dry to prevent electrocution hazards.
