A=COM 4.2.2 No employee shall use any hand or power tool, unless they are familiar with the use and operation of the equipment or have received specific instruction on its use and operation. 4.2.3 All tools will be used for which they were designed and in accordance with manufacturer's specifications. Do not use tools for jobs they are not intended for. For example, do not use a slot screw driver as a chisel, pry bar,wedge or punch or wrenches as hammers. 4.2.4 Use approved tools only. Never modify or use makeshift tools. 4.2.5 Do not apply excessive force or pressure on tools unless permitted by the manufacturer's specifications.This includes additional force by hammering with body weight,foot or other tools. 4.2.6 Keep surfaces and handles clean and free of excess oil and grease to prevent slipping. 4.2.7 Do not carry sharp tools(e.g. knife, chisel, screwdriver, etc.) in pockets; this practice may cause puncture wounds. 4.2.8 All tools shall be properly maintained. Clean, dry, lubricate and repair tools as applicable, and return to a suitable toolbox, room, rack, or other storage area upon completion of a job. 4.2.9 Ensure proper ergonomics principles are observed when using hand and power tools, such as but not limited to: • Avoid static and awkward positions when possible. o Move at intervals to reduce muscle fatigue. o Consider tools with a trigger strip, rather than a trigger button. This strip will allow the exertion of more force over a greater area of the hand that, in turn, will reduce muscle fatigue • Do not apply excessive force or pressure on tools. • If possible use tools with comfortable grips that are designed to allow the wrist to stay straight. Avoid using a bent wrist. • Choose hand tools that have a centre of gravity within or close to the handle. • Frequently used tools that weigh more than 1 pound (0.45 kilograms)should be counter- balanced. • Ensure proper body positioning when using a tool to prevent slips or falls in the event of unanticipated tool behaviour(slip, kickback, etc.). Avoid over-reaching. • Pull on tools such as a wrench or pliers whenever possible. Loss of balance is more likely when pushing if the tool slips. If pushing is necessary, hold the tool with an open palm. • Hand-arm vibration exposure is associated with the use of hand tools. o Reduce power to the lowest setting that can complete the job safely.This action reduces tool vibration at the source. o Consider the need for controls such as limiting time of use. o If safe to do so, adjust to a looser but stable grip, and use anti-vibration gloves. • Use of heavy tools such as jackhammers can cause fatigue and strains. Heavy rubber grips can reduce these effects by providing a secure handhold. • Do not increase a tool's leverage by adding sleeved additions(e.g. a pipe or snipe)to increase tool handle length. 4.2.10 Avoid placing fingers and hands in danger zones: • Ensure hands and fingers have sufficient clearance in the event the tool slips. • Ensure stability of the work-piece. Use work-piece holders(e.g.vise, chisel holder, etc.) whenever possible to prevent injury to hands or deflection of tool or work-piece.
