In comparison to the frequency of accidents for people who weigh normally (15%), middle-aged and older obese adults fall as much as 27% in a given year (Fjeldstad, Fjeldstad, Acree, Nickel &amp; Gardner, 2008).<\/p>\n<p>Statistics suggest that over 85% of manufacturing employees are obese or overweight (Pollack, et al., 2007).\u00a0 Because of these numbers, a study has been conducted to illuminate the visible correlation between weight and the risk of falling, and the causes by which these accidents occur.<\/p>\n<h2>Obesity impairs balance when walking<\/h2>\n<p>The study conducted by Dr. Jian Liu from the Center for Neuromotor and Biomechanics Research at the University of Houston postulates that while there are inconclusive findings regarding the correlation between Body Mass Index (BMI) and postural instability among the overweight, the risk of slip-induced accidents might lie with dynamic processes such as walking.\u00a0 The purpose of their study is to detect the causation of the variance between normal-weighted individuals and the obese (Liu, 2010).<\/p>\n<p>The laboratory study involved twelve young adults, ages ranging from 18-26.\u00a0 Seven of which were considered normal weight by the CDC, and five were classified as overweight.\u00a0 Several tests were performed including various postural stability checks.\u00a0 Subjects were instructed to walk on an instrumental split-belt treadmill at their regular pace to measure friction demand (required coefficient of friction).<\/p>\n<p>The required coefficient of friction (RCOF) pertains to the minimum amount of friction necessary between floors and shoes in order to support walking (Chang, Chang &amp; Matz, 2010).\u00a0 The number relates to the traverse shear component involved with the shoe and floor interface.\u00a0 Slip and fall is initiated when the heel does not firmly make contact with the floor.<\/p>\n<p>The results of the study prove that the overweight group, as a whole, required a 17.5% higher friction than their normal counterparts.\u00a0\u00a0 A higher BMI could mean that the traverse shear component increases as the heel meets the floor.\u00a0 The higher RCOF quantifies the increased need of surer footing because of the pressure applied by the feet.\u00a0 Because of the higher required coefficient of friction that is needed, the overweight are more likely to slip and fall on slippery surfaces.<\/p>\n<p>In addition to the higher friction demand, computer simulations display that as body fat increases, the ankle torque necessary exponentially rises in proportion.\u00a0 The higher body mass also multiplies the inertia on the ankle joint (Corbeil et al. 2001), which means that obese people will not be able to react as quickly during initiated slippage.<\/p>\n<h2>Ensure employee safety by using floor protective coverings<\/h2>\n<p>Help minimize premises liability for employees through investing in floor mats for safety. Adding <a title=\"floor mats\" href=\"http:\/\/www.eaglemat.com\">floor mats<\/a> will increase traction on surfaces and minimize traverse shear components, which will ensure surer footing for employees.<\/p>\n<p>Investing in the commercial floor mats reduces the risk of falling by helping shoes adhere better to the floor surface at the point of interface.\u00a0 <a title=\"Entrance mats\" href=\"http:\/\/www.eaglemat.com\/entrance-mats-runners.html\">Entrance mats<\/a> in particular may minimize the amount of debris and moisture carried by shoes, thus removing another component that would lead to accidents.<\/p>\n<p>Guaranteeing employee safety, regardless of their weight and condition, should be the top priority of any business.\u00a0 Using floor mats, employers create a safe and clean environment in the workplace, and reduce the potential litigation costs of liability.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Resources for this special safety report include:<\/strong><\/p>\n<p>Center for Disease Control and Prevention.
