Observing the contractor area working on new warehouse construction, it was noticed that they installed an electrical control panel, switch and cables located outside of building, in open area which may expose the panel, switch and cables to rain water. During the audit it was not proven that this electrical installation has correct Ingress Protection (IP) rating for the installation as per international standard IEC 60529. It was shown that an inspection was done by Electrician and safety officer that the panel was prohibited to be used due to no IP rating information, however it was seen that the electrical panel was still at the area and no tag or warning sign to prevent the use the electrical installation. The Plant could not ensure whether the electrical installation was used or not by the contractor. It was only said that the inspection result was informed to the contractor. (Note: the electrical installation was not in use during plant tour due to public holiday).
