Question

a. What are the two main hazards associated with chemical plants and list three examples of each?

What are Material Safety Data Sheets (MSDSs) and the role of MSDS in Process Design?

Answer 1

Hazards in chemical plants are classified into:-

1) physical hazards:-

Examples of physical hazards are .......

a.... Explosion of explosive chemicals

b.... Inflammations of volatile chemicals like LPG.

c....leakage of compressed toxic gases like methane.

2) Health hazards:-

Examples of health related hazards are

a...almost all the organic chemicals are carcinogenic.

b...Allergic effects can be produced by some fuming liquids like ammonia.

C....Radioactive chemicals can be fatal.

Material safety data sheets (MSDs) provide basic information about the chemicals viz. their use, safety issues and precautions etc.

During the process designing MDS plays a very important role as it depicts the following:-

Name of manufacturer

Date of manufacture

Hazards related to the material

Precautions required

How to use the material safely..

In other words MDS tells about the Do's and don'ts regarding a chemical.
