industrial safety dose not happen.companies with low accident rates plan their safety programs, work hark to organize them ,and continue working to keep them alive and active. when the work is well done, a climate of accident-free operations is established where time lost due to injuries is kept at a minimum.

工业生产安全环境并不是偶然出现的。那些事故率比较低的公司通常会仔细制定安全计划，努力组织实施计划，并不间断的保持计划的有效性和活力。 当所有这些工作实现时，一种能够真正避免事故的生产活动就会实现，因此因为救护伤员而导致的生产时间的损失也会降到最小。

感觉意思翻译到位了。
