Most electricians are always in the market for new tools. While some electricians are tool hounds and like to keep up with the latest innovation, for the rest, there are still compelling reasons to upgrade or replace. First of all, tools are expendable. No matter how careful a worker is, old tools (or even relatively new tools) drop and break, develop flaws that compromise safety or walk from the job site. Some just wear out. And then, for those that are durable, time may change their status. What looked like a state-of-the-art tool a few years ago might seem heavy and clumsy today when compared to newer versions or might not offer the ergonomic design or safety features that today’s tools carry as a matter of course. Given the recent surge of improvements in the design or built-in performance characteristics of various hand and power tools, it pays to take a closer look at what’s available in the current crop of offerings. The enhancements could make a big difference in comfort, productivity and prevention of repetitive motion injuries, and in safety.
It is cost efficient to not skimp when buying new tools. If a new tool boosts productivity or decreases risk of injury, that advantage effectively amortizes the cost quickly, in terms of the bottom dollar or peace of mind. (For many companies, buying new tools is an expected expense. Some electrical contractors routinely include in their bid a percent factor of job cost to cover tool replacement; others include a flat tool rate based on the job size.)
There are many benefits to ergonomic and other comfort features. Compressible handles allow a worker to press less hard to maintain control of the tool during operation. A non-slip or slip-resistant handle can help prevent injury resulting from an electrician losing a grip. (Work gloves may also provide some protection.) Some power tools also feature vibration-absorbing rubber boots around the torso of the tool, to help reduce hand fatigue.
One across-the-board rule of thumb: only use a tool for its intended purpose. Any misapplication or extension of function beyond the intended one risks tool damage, marring of the work piece or, most importantly, injury to the worker or a bystander. Better to travel heavy than to use a tool beyond its bounds. Only use tools that are in good working order. For safety, don’t jerry-rig an extension handle for leverage or any other reason. The tool could snap and the operator could get hurt by loss of balance or by a suddenly released tool fragment or work piece. Keep the moving parts of any tool clean, tight and properly lubricated. And, if working on or near live wires with hand tools, always use rated insulated hand tools. When selecting new portable power tools, look for double insulation for protection from electric shock when using the tool.
Overall, the best buys are those that satisfy a combination of factors: productivity benefits, budget, comfort—how the tool feels in the hand (its grip, weight and balance), ease of operation and safety. Safety should always be the first consideration. In power tools, also evaluate the trigger location, design and action, the handle locations and size (and whether there is room for gloves) and switch location. EC
