Lifting Matters Issue 8 November 2009

  1. 1. Aging Workforce: New Challenges in Safety and Disability Research According to the U.S. Bureau of Labour Statistics (BLS), the number of workers over age 55 will increase by nearly 40 percent, and the number of workers over age 65 will almost double over the next 10 years. (BLS, Monthly Labour Review, November 2007). The stats for Australia are very comparable. I’ve featured just two questions and answers from the Liberty Mutual Research Institute for Safety quarterly review Summer 2009. RDP Q LIFTING MATTERS Are older workers more injury prone than younger workers? A According to Bureau of Labour Statistics data, older work- Published in the interest of promoting safety in the crane industry ers actually have fewer lost-time injuries than younger workers per full-time equivalent. However, for older workers who do experience a lost-time injury, the average length of disability is longer than that of their younger counterparts. One study Sharing and Learning showed that the cost per lost-time workers compensation claim for workers aged 45-64 was more than twice that of workers aged 20-24.1 Some researchers speculate that the greater length of disability is associated with longer work absences due to retirement from the workforce after the injury. 1 1 Restrepo, T., Sobel, S., and Shuford, H., “Age as a Driver of Frequency and Severity,” National Council on Compensation Insurance Research Brief, December, 2006 Q How do older workers “measure up” to their younger counterparts? A In many jobs, the experience, quality, and learned efficiencies of older workers can actually make them more productive than younger workers. Older workers are less likely to miss work due to non-health reasons (e.g., family obligations) and typically develop compensatory strategies (time-acquired skills) that make them as effective as − and often more effective than − younger workers for many kinds of tasks. Sometimes a trade- off exists, with older workers producing higher quality work, even though speed might be somewhat decreased. 1 1 Liberty Mutual Loss Prevention Reference Note 5439, 2008 WWW.SAFTENG.NET CRAZY ROOFER 19TH NOVEMBER 2009 A lone roofer was spotted by a reader as he passed though Darlington in the UK, he certainly has a Death Wish.
