"Health is everything". This is not merely a phrase. It is something of utmost importance for all the mankind. People in this world are slightly blinded by the lust for money. They give their 100% to the work and some people work even more than their actual capacity, which increases the chances of their meeting workplace accidents.
Health and safety trainings are given to such people who want to succeed in their work life. They are trained on how they can give their level best performance without compromising the health and safety of their own.
In America, about 2% of the accidents take place because of lack of awareness about the safety precaution. About 10% people get sick at the workplace due to bad hygiene. Recently in China, a workplace accident took place which killed 80% of the staffs of the company. That happens. If you give yourself and your staffs necessary training for the accident then they are more likely to survive the accident and your business won't face loss in any sense.
