HAND ANTHROPOMETRY SURVEY FOR THE COLOMBIAN POPULATION
ABSTRACT During the in course semester, a number of students from a Colombian college, Universidad Del Norte studied anthropometric measures from a population of 192 workers in the manufacture industry. Throughout this paper, genders and ages will be compared by analyzing and comparing various indices (e.g. percentile values, standard deviations, mean values, etc.), with aid of charts and graphics, extracted from the selected sample from Barranquilla’s population vs. Bangladeshis’, Nigerians’, Vietnamese’s, Americans’, Japanese’s, Chinese’s, British, Americans’ and Mexicans’. The importance of these results relies on the provision and exposure of differences between South Americans’ (more precisely, Barranquilla’s) and European, North American, African or Asian populations, in anthropometric terms. The analysis of these results would then provide a solid base on how hand tools or some kinds of machinery should be designed, looking forward to preserve ergonomic principles, focused on the jurisdiction cleared earlier. of these factors affect the productivity of the organization. Therefore, various researchers have pointed out the importance of using relevant anthropometric data in equipment design. In the United States, it has been estimated that there are over 260,000 hand tool injuries each year and it is believed that worker–tool mismatches have contributed to these injuries to some extent. Is a fact that the industrialized countries are lacking of data that contains information of the 1
1. INTRODUCTION In order to achieve a productive organization is very important that the workers have adequate resources as equipment, hand tools and machinery to accomplish every task in the appropriated conditionsand be compatible with the physical characteristics of the workers. If the company doesn’t reach these parameters it can contribute in some factors and discomfort, accidents, fatigue, injuries and other diseases. All
anthropometric measures of the people. Design improvements in equipment may be necessary for safety, health and Comfort because of differences in the size of certain body dimensions. Research has shown that there are anthropometric differences between different populations in almost every part of the human body (Abeysekera and Shahnavaz, 1989). Important dimensions in question include stature,sitting height, and those of the hand (Abeysekera and Shahnavaz, 1989). It’s important to collect information of these hand measures so the industries that make these tools make changes in the design and provide some benefits to the workers and companies. As pointed out by Norris and Wilson (1997) and Xiaoet al. (2005), anthropometric data are essential in order to design safe and efﬁcient workplace, equipment and tools. For example, a hand tool with the trigger designed to ﬁt most male hands comfortably is likely to be too large for most females. It may require the trigger to be squeezed with distal ﬁnger segment instead of the middleone, inducing greater strain on the ﬁnger tendons. Hand anthropometry measurements, relevant to the design of hand tools and other manual devices, have been published for various nationalities, such as ethnic Vietnamese living in USA (Imrhan et al., 1993), United Kingdomfemales (Davies et al., 1980), Hong Kong Chinese females(Courtney, 1984), Indian agricultural workers
(Karunanithi et al., 2001), Western Nigerian rural farm workers (Okunribido, 2000), Eastern Indians (Kar et al., 2003), Central Indian farm workers (Gite and Yadav, 1989),Mexicans (Imrhan and Contreras, 2005), Bangladesh females (Imrhan et al., 2005), Bangladesh males (Imrhanet al., 2006), and few hand anthropometric dimensions hasalso measured for Filipino manufacturing workers (DelPrado-Lu, 2007). In an effort to account for the effects ofthe differences in anthropometric dimensions between people of India and Western Europe noted by Sen et al. (1977) and Gupta et...
