With the rise of the construction industry, more and more cranes have been put into use, and the workplace safety has been paid more and more attention.According to a data survey by Osha, 249 high-altitude crane accidents in 10 years have involved 838 violations, the fine of 2.3 million US dollars, the estimated economic loss of more than 500 million US dollars, and an average disability cost of more than 200,000 US dollars. The average cost of death exceeds $4 million.It can be knew that a huge loss is caused to a company, not just this aspect.,let us assume that a production enterprise, due to an accident caused by a crane, not only will the personnel be injured, there will be employee insurance and the company’s economy causing losses, and at the same time, the goods , machine also will be damaged, coupled with the delay of work due to machine damage, these are invisible huge losses; And in terms of interpersonal relationships, companies with frequent accidents have a bad influence on employee and business relationships, which may hinder the introduction of excellent talents, leading to the loss of existing employees, and the corporate public image has a huge impact, which may lead to strict government monitoring and mandatory measures by the safety supervision department. This is a scene that a successful enterprise is very reluctant to see.In fact, the safety protection of work scenes has been taken seriously by the international community. Many countries have issued relevant safety regulations, such as the requirements for work clothes in the metallurgical industry; in some workplaces, they require the use of sound or light warning products etc.No matter where we come from in the world, I believe that our philosophy of pursuing safety is always the same.
