Abstract

A cast metal company has become a vital industrial sector. It creates various kinds of products like cages, souvenirs, kitchen appliances, ashtrays, ship joint shafts, hotplates, fitness equipment, manual water pumps, pendulum scales, garden benches, lamp posts, interior lights, wall lamps, grills, manhole, and other types of equipment to deal with workplace safety. However, some workers ignore the various potential hazards during the production process. They are more concerned with comfort aspects than safety. This research enhances occupational safety and health (OSH) aspects through Hazard Identification Risk Assessment Risk Control (HIRARC). It is done by identifying potential hazards in the workplace and making a hazard risk assessment to determine appropriate controls for reducing the hazard risks. Based on hazard identification and risk assessment, the results show 11 high, 2 medium-risk, and 1 low-risk levels. The risk control proposals are in the form of training on the importance of OSH among employees/workers. It also raises awareness to provide work safety facilities and establish policies related to OSH.

Abstract

Less ergonomic work postures such as bending and squatting have the potential to pose work risks. When muscles receive static loads repeatedly and for a long time, it causes complaints of damage to joints, ligaments, and tendons commonly referred to as musculoskeletal disorders (MSDs) or injuries to the musculoskeletal system. This study aimed to determine the level of risk of work postures performed by workers in each work activity using the Rapid Entire Body Assessment (REBA) and Ovako Working Posture Analysis System (OWAS) methods and provide suggestions for improving work postures to minimise the occurrence of work risks. The research was conducted at the foundry of metal in the Casting section. Initial data in the form of Nordic Body Map (NBM) questionnaire data used to determine complaints in the musculoskeletal system and data in the form of image documentation on each work activity used as material for analysing the assessment of the REBA and OWAS methods. Proposals for improving the working posture were given in the form of adding foundations for moulding and pattern-making activities, the design of tools for metal liquid pouring activities, and furnace designs for metal smelting.
