Chapter 19, Problem 11STP

Summary Introduction

To analyze : 

The safety equipment is required while experimenting with the extraction of the pigments that involve the boiling of different leaves and flower petals in different solutions. 

Introduction :

While performing scientific experiments in a laboratory, one must always dress for work to avoid laboratory accidents. Constant vigilance and care is a necessary step that must be taken by doing laboratory work.

Explanation of Solution

While performing an experiment that involves boiling of leaves and flower petals in a different solution, one must take care of the following things: -

• Exposed skin must be covered by clothing and shoes that are chemical resistant, such as lab coats. It protects the skin in case of a chemical splash or from the boiling liquid.
• Hair must be tied and cosmetics must be removed as some of them could be volatile or inflammable.
• To protect the eyes from the vapors while boiling or from the volatile substance safety goggles must be used.
• Disposable gloves will prevent the hands from getting in contact with anything contaminated or harmful while experimenting.
• The fire extinguisher should be handy and within the reach to avoid possible mishappenings while doing such experiments that involve fire.

Conclusion

Thus, while experimenting, all the safety equipment must be used properly to avoid accidents. The experiments in which there is a use of chemicals and fire, one must always protect its bare skin using gloves, lab coats, goggles, etc. A fire extinguisher must always be there to prevent the fire from spreading in case of an accident.
