Question

A chemical engineering has been working with a local manufacturing firm. For several years the firm has been using chemical A as a solvent in their manufacturing process. Chemical A is carcinogenic, although studies supporting this claim have only recently been published. Without taking elaborate safety precautions, workers handling chemical A would be exposed to sufficient amounts to risk cancer. Moreover, the disease takes up to 20 years to manifest itself. The company has tried to implement safety procedures and controls, but workers routinely ignore them. The safety procedures slow down the manufacturing process, and the workers frequently cut corners to meet quotas. The chemical engineer knows of another chemical, B, which also serves as a catalyst in this manufacturing process but is not carcinogenic. Nevertheless, chemical B is considerably more expensive.

What should she do? Elaborate with details.

Give example about replacing dangerous solvent with a relatively safer one  

Answer 1

the chemical A would be one of them benzene, beryllium, asbestos, vinyl chloride, and arsenic and using these chemical cause cancer in humans these chemicl should be replaced by the alternative chemicals and alternatives of these above carcinogenic chemicals is given below

carcinogenic chemicals	alternative chemicals
benzene	cyclohexane
arsenic	borates
vinyl chloride	high density polyethylene
asbestos	polyurethan foams
beryllium	carbon fibre composite

the human safety is first in all condition

if the alternative chemicals of the carcinogenic are of very high cost and the profit geneted from the plant is very less or no profit is there then the plant should be closed very soon

the human safety is at any cost no matter how much time the disease take to manifest  

there is certain rules and regulation for the human safety if you will avoid them and does not follow then you can be in serious trouble. the goverment have right to shut your plant and charge a heavy fine to your plant. In some cases can be put behind the bars.

so do follow the safety rules stictly and force the worker too to follow the safety norms.
