Dear Members / IOSH Team, Please forget any typos Can anyone please assist me with an unclear definition regarding work relatedness classification for an incident that recently occurred at the construction project I am working on in Indonesia, which follows OSHA guidance and not HSE. Background: This incident involved a person who was using a squatting type portaloo which is a common type used throughout Indonesia. Local culture is that they remove shoes, sock, trousers etc. before defecating. The portaloo was located on the project worksite and when the person used this for some reason he ended up standing in the sunken toilet bowl. With the weight of the IP the ceramic bowl seperated and his bare leg caught the sharp remaing ceramic edge. This resulted in a deep gash and the rupture of his Achillies tendon. When he was stabilised at the onsite clinic he was sent to the local hospital which is around 90 minutes drive. When he arrived there the surgeon was on holiday so he was then transported to another hospital ten hours away to whcih there was also no surgeon available. He was eventually seen and operated on some 44 hours later and then released the next day. OSHA is unclear in whether this incident was at work i.e. due to the location of the toilet or whether the person was not at work as he wasn't undertaking any work activities. Things like chocking on a sandwhich in the works canteen are not classified as work related so is doing the toliet classed as work related or not. Please can anyone assist who may have experienced this type of incidnet or are there any legal personnel who can definently define work related or non occupational. Please accept my apologies if my replies are late due to time difference and frequent loss of internet service due to my remote location.
