Interpretation Introduction

Interpretation:

The appropriate clothing to be worn in a chemistry lab is to be described.

Concept introduction:

When working in a chemistry laboratory, it is very important to follow certain guidelines so as to avoid any accident. Chemists use special tools and equipment that allow them to perform experiments in labs. They have to follow safety rules in handling of dangerous tools and chemicals. They should dress appropriately in order to avoid any accident.

Answer to Problem 2E

Some guidelines for appropriate clothing to be followed in a lab include:

1. Pants should cover the legs up to the ankles.
2. The sleeves of the shirt must be rolled up.
3. Closed - toe shoes should be worn.
4. Safety eyeglasses/ goggles should be put on before starting the experiment.
5. Gloves must be used.
6. Lab coats should be worn.
7. Long hair must be tied back.
8. Short skirt or dress should be avoided.

Explanation of Solution

Given information:

Working in a chemistry lab involves wearing appropriate clothing that are important to work safely and carefully.

Clothing - The pants should be long enough to cover the legs upto the feet so that if anything falls on the legs, there is no direct contact with the skin. The shirt, shoes and lab coat protect the body from any accidental spillage of chemicals. Short dresses, skirts and open shoes should not be worn as thy may fail to prevent skin burns due to spillage of chemicals. The hair must be tied back to avoid any kind of distraction.

Gloves - These protect the hands from toxic chemicals so they should be worn at all times in the lab.

Eye protection - One should wear proper safety glasses or goggles to protect the eyes from toxic chemicals that might splash into the eyes. One must put on safety goggles before working with chemicals or glassware.

Conclusion

One should be properly prepared to work in a laboratory with appropriate dressing so as to ensure that there is no accident due to hazardous chemicals. Personal protection equipment is necessary to prevent any incident in the lab.
