Interpretation:
The three things one should do before beginning any laboratory procedure are to be listed.
Concept introduction:
While working in a chemistry laboratory, it is very important to follow certain do’s and don’ts. These help in preventing accidents.
Answer to Problem 3E
Before beginning any laboratory procedure, one should follow the following things:
- One must be dressed appropriately with sleeves rolled up; hair tied back and closed - toe shoes worn.
- The instructions for the experiment must be read carefully.
- One must be familiar with safety equipment in the lab.
Explanation of Solution
Given information:
There are certain do’s and don’ts to be followed in laboratory before beginning an experiment.
Proper dressing is necessary to avoid any accident due to spillage of harmful chemicals or breakage of glassware. Chemists use specialized tools, chemicals and equipment in the laboratory. It is very important to work safely and carefully with these tools and chemicals. Sleeves should be rolled so that there is no chance of it catching fire. Long hair must be tied back so that there is no distraction while working. Shoes should cover the feet completely to prevent any harm to the feet due to anything falling over or spillage of chemicals.
One must read the instructions carefully before the start of the experiment so as to get familiar with the procedure and be prepared for the safety precautions to follow while performing the experiment.
One must be familiar with the safety equipment in the lab. Before participating in any chemistry activity, one must know where the safety equipment is kept so that on case of any emergency one can easily reach out to them.
Safety is very important while working in a chemistry laboratory. By following certain rules and guidelines before beginning an experiment, one can avoid any unwanted incident.
