About this blog
Test and tag of electrical equipment is the process through which safety for use is ascertained of electrical appliances. All companies utilize a multitude of appliances for operational running. Some organizations, however, are more reliant on electrical equipment than others. These include the construction and mining industries where everyday work revolves around the handling of large appliances.
These appliances are central to these industries and have no doubt to some extent eradicated back breaking manual labor, instead of deploying machines to do the heavy lifting so to say. While this is an astronomical step forward, the notion can only stand its ground if the safety of workers and operators is guaranteed.
A brief summation of Testing and Tagging procedures.
All appliances in our daily use suffer wear and tear. Even though the most careful of usage, perfect condition of appliances cannot be prolonged. While fulfilling the purpose of deployment, appliances get damaged and the continued use of electrical appliances in a damaged condition can lead to very damaging consequences.
It is for this very reason that electrical contracting companies exist which provides services for the testing of electrical equipment and ascertains proper working condition. Thus ensuring the safety of workers and all others in contact with said equipment.
The testing of electrical equipment is a relatively simple procedure. It should be ensured that the person called upon to perform the testing is certified and experienced, in order to be sure of the validity and accuracy of the results.
Testing of electrical equipment takes two forms namely physical and electrical. Physical inspection serves to make note of any visible signs of defect. For this purpose, the appliance ought to be removed from the place of use to view all around. Visible signs of defect, however minor ought to be paid attention to. These could include frayed cords or a door or any other fitting not closing properly.
The second part of the inspection, which is electrical inspection is performed through the use of portable appliance testers. The readings are then evaluated by the technician and appliances are appropriately tagged.
Test and Tag colors.
While some countries require specific colors to be used for the purpose of testing and tagging, there is no stringent requirement for any specific colors to be used. For instance, primarily red, blue, green and yellow are used for tagging. But other colors such as grey, burgundy or orange can also be used. What is essential here is that a meticulous record is maintained to ensure clear and concise communication and comprehension in case of any issues. Usually, an established industry practice is followed, which can be better explained by the use of an example.
Legislative laws in Australia require that tagging of equipment in the construction, mining and demolition industries adhere to the following color codes:
· Red tags be used for December, January, and February
· Green tags be used for March, April, and May
· Blue tags be used for June, July, and August
· Yellow tags be used for September, October, and November
Uniformity in the use of testing and tagging colors enables easy recognition and thus removes any confusion regarding the time at which equipment was tested. Differentiation between the tagging colors can only be meaningful if the color codes are both established and uniform. However, even in the case of a non-uniform color code being deployed in the industry, maintenance of adequate records can be extremely helpful.
As a general rule, test and tag should be carried out regularly to ensure the optimum working condition of equipment and to determine the safety of all those in the proximity to the appliances.
