Why were unsafe working conditions common during the second industrial revolution

Factory smoke and other conditions

Explanation:

Back in the second industrial revolution there were many factories being built, and there were a lot of people willing to work for lower wages. Conditions were harsh, as there was a lot of smog, factory smoke, etc. and many people were harmed by the many machines in factories that had no safety precautions. Also, the gases and smoke caused breathing and lung illnesses.

Fast paced

Explanation:

Everything in both of the industrial revolutions was all fast paced. They wanted skilled or less-skilled workers who would take little pay. And during this time there was a lot of poor families who would take the job opportunity. Since everything was fast paced they didn't have much time to fix the working conditions. Their main focus was to get the product completed and sold. But later on in the 2nd revolution, the working conditions did get better.
