OSHA Press Release Links Improved Safety to OSHA’s Efforts

Picture 25-1

In a recent press release from OSHA, the following quotes linked the improvements to OSHA’s efforts:

The rate of workplace injuries and illnesses in private industry declined in 2007 for the sixth consecutive year, the U.S. Department of Labor’s Bureau of Labor Statistics (BLS) reported today. Nonfatal workplace injuries and illnesses reported by private industry employers declined from 4.4 cases per 100 workers in 2006 to 4.2 cases in 2007.

“The 21 percent decline in the workplace injury and illness rate over the past six years and a 4.5 percent decline over the past year show the effectiveness of the strategy of targeted enforcement coupled with prevention through compliance assistance to promote a culture of safety at the workplace,” said Secretary of Labor Elaine L. Chao.

Assistant Secretary of Labor for Occupational Safety and Health Edwin G. Foulke Jr. said, “Today’s injury and illness results demonstrate that OSHA’s balanced approach to workplace safety encompassing education, training, information sharing, inspection, regulation and aggressive enforcement is achieving significant reductions in workplace injury and illness throughout the country. This report shows that employees are now safer in the workplace than ever before. This success validates our efforts, and we are redoubling this commitment to make workplaces even safer.”

Is a 21% decline over 6 years or a 4.5% decline year over year statistically significant?

If it is, what is the proof that the decline was in some way related to OSHA’s efforts?

Since we have trained thousands of people in the US to use TapRooT® in the past six years, could we claim that TapRooT® was responsible for the 21% decline?

Statistics are interesting. If you are interested in improved use of statistics and answering the question of what is a statistically significant change in a measure, you should consider attending an Advanced Trending Techniques Course. Unfortunately, you missed the recent course. But we will be holding one on October 5-6, 2009, in Nashville, TN.

If you have a group of people interested, we could hold the course for you at your site. Call us at 865-539-2139 or e-mail us by clicking here for a quote.
