Certification Meter
Structured cabling systems thatadhere to installation standardsare required to be certified.Certification meters perform all
of the required performancetests to adhere to theANSI/TIA/EIA-568-B standards
In addition to certification, these
meters include diagnosticfeatures that will actually showhow far these problems are fromthe end of the cable being tested

Tool Usage and Material Handling
Before using a new tool, read theaccompanying documentation, study thedevice, and ask for assistance from an
experienced installer It is better to ask for help than get hurt, hurt
someone else, or damage an expensivepiece of equipment
Expensive tools are generally moreeconomical in the long run since they typicallyare built to last for many years

Material Safety Data Sheet (MSDS)
A material safety data sheet (MSDS) is adocument that contains information on theuse, storage, and handling of a hazardous
material It tells what the hazards of the material are,
how to use it safely, what to expect if therecommendations are not followed, what to doif accidents occur, how to recognizesymptoms of overexposure, and what to do ifsuch incidents occur
