Both of the shredders differ from each other as per the number of smaller particles created from the shredded document. The capacity of the shredders of level 5 is to reduce the size of a document in to six thousand unidentifiable particles. These shredders are primarily used in law offices as well as hospital and also in other business that require the elimination of certain confidential documents. The capacity of the shredders of level 6 is to reduce the whole document in to more than twelve thousand smaller pieces of paper. These shredders are mostly used in the case of highly confidential government documents like those of the military.
For the better security of the papers being shredded, the task of shredding the papers should be given to a known as well as trusted staff or member of the organization. Security is a major issue while dealing with the shredding contractors. The shredding contractors are after all outsiders. It is also important to check the device being used by the contractor to shred the papers. It is also possible that the contractors may be using equipments that are less secure. Most of the shredding manufacturers like Fellowes, Swordfish, Draper and Aurora use shredders with half inch wide strip. They usually do this for having a maximum speed of shredding the papers. However, this may not be secure for a business company.
One good way to secure the shredding of the papers by paper shredders is to use shredder oil. The shredders cylinders are lubricated by the shredder oils only. Other oil or lubricant if used in the shredder, will empty the warranty of the manufacturer. This triggers the cutting capacity of the shredder. The following security levels are to be used in various shredding activities.
Security level 1 is required for the shredding of general documents. The security level 2 is used to shred the internal sensitive documents. The security level 3 may be used for shredding the confidential documents. The security level 4 is used to shred the secret documents. The next security level, i.e. high security level 5 is involved in shredding those documents that are extremely confidential. The final level- the high security level 6 is used for shredding the top secret documents, usually involving confidential matters of a country.
