Hand tools are used in almost every trade, but many of them have particular applications in a specific trade. It is likely you have used some of these tools already at work, at school, or at home, but this may be the first time you have had the chance to study some of the tools' designs and applications in detail. The following list of lines and competencies was generated with the goal of creating an entry-level trades training resource, while still offering the flexibility for lines to be used as stand-alone books. Line C - Tools and Equipment. C-1 Describe Common Hand Tools and Their Uses, C-2 Describe Common Power Tools and Their Uses, C-3 Describe Rigging and Hoisting Equipment, C-4 Describe Ladders and Platforms.
