Abstract [en]

This master thesis concerns work environmental risks that are a part of the modern steel industry. The result is a tool that can be used for identifying unwanted risks, which usually are hard to identify. The content of the tool is based on results from extensive literature studies, statistical analyses and qualitative in-depth interviews with the persons that are exposed for the risks on a daily basis.The master thesis project was conducted during the spring of 2015 as a final project of the civil engineering program Technical design at Luleå University of Technology. Ovako AB was the outsourcer and the studies were carried out on their production plant in Hällefors. The production in Hällefors included the making of hot rolled, peeled and ground bar and wire and also the manufacturing of pre-components from bars. The plant in Hällefors was certified with ISO 14001, OHSAS 18001, ISO 9001 and TS 16949.The statistical analyses showed that crushing injuries and other soft tissue injuries were the most common type of injuries at the production plant in Hällefors during the time period 1/1 2014 – 28/4 2015. The second most common type of injuries was cutting injuries, sprains and muscle strains. During the same time period the most frequently reported reasons for an injury or a close call were getting hit by a flying or a falling object. The second most common reason was getting stuck or crushed between objects. The qualitative in-depth interviews pointed out that crushing injuries, cutting injuries, injuries from falls, burns and repetitive strain injuries were the most common injury types at the production plant in Hällefors. The interviewees described that tangled bundles, crooked bars, short bars, sharp edges on cut bars, work up on machines and loading tables, slippery surfaces, welding spatters and the manoeuvring of overhead cranes and vehicles are the biggest reasons why accidents occurs.The tool has the form of a checklist and the content is, based on the results from the study, divided in five different areas; Physical work environment, Psychological work environment, Ergonomics and work methods, Technical facilities and hand-held tools and at last Machines, vehicles and automation. The main part of the questions focuses on the risks with manual lifting and manual handling, but physical environmental factors and the functionality of machines also stands for a big part.The recommendation to Ovako is to implement the risk identifying tool at their unit in Hällefors and continue the development of the content. There are many positive sides with a safe work environment and good working conditions. Wellbeing of the employees, financial benefits for the company and stronger competitive forces are just some of these. The result of this master thesis project are applicable for other type of businesses in the industry sector. However, the tool needs to be optimized based on the specific work conditions to obtain optimal benefits.Safety needs priority!
