Electrical, Mechanical, and Personal Safeguarding—Part 1
Published in Ron C. McKinnon, Risk-based, Management-led, Audit-driven, Safety Management Systems, 2016
The safety element standard for the safe selection and use of hand tools should include the use of the correct tool for the job in hand, prohibiting the use of makeshift or homemade hand tools, keeping hand tools in a good condition, correct tool storage, keeping tools in a safe place to ensure that they do not fall from overhead, correct training, and the regular inspection of hand tools.
Construction Safety
Published in W. David Yates, Safety Professional’s, 2015
Hand tools are nonpowered and include anything from axes to wrenches. The greatest hazards posed by hand tools result from misuse and improper maintenance. For example, dull chisels cause many accidents that could have been avoided. Other hazards associated with the misuse or improper maintenance may include Using a screwdriver as a chisel, causing the tip of the screwdriver to break and hit an employee in the eye or cause a puncture wound.Wooden handles on a hammers or axes may become loose and fly off and strike a bystander.A wrench whose jaws are sprung might slip, creating “busted knuckle.”

A sign of a good worker is a clean and tidy working area. Only the minimum of tools for the job should be laid out at any one time. These tools should be laid out in a tidy and logical manner so that they immediately fall to hand. Tools not immediately required should be cleaned and properly stored away. All hand tools should be regularly checked and kept in good condition. Spillages, either on the workbench or on the floor should be cleaned up immediately.

A 3D model of a robot that is planned to be deployed in the debris retrieval work and its specification are shown in the left column of Figure 4. It consists of a dual-arm manipulator and a telescopic ladder-type access rail for carrying the manipulator to an appropriate operation point around the pedestal for further work. Once the manipulator is in place, the access rail is no longer moved. Each arm has eight degrees of freedom, and the base of the manipulator is equipped with a pan/tilt mechanism for inclination and turning. A cutter tool and a hand tool are attached to the end-effectors. The cutter tool is used to cut an obstacle, and the hand tool is used to fix the obstacle during cutting. Since the debris retrieval robot described above is still under development, MEISTeRII (Mitsubishi Heavy Industries, [14]), shown in the right column of Figure 4, is used for the experiments conducted in this study. This robot is equipped with two arms with similar kinematic structure, and therefore considered to be appropriate for preliminary experiments.

The handles of tools are commonly used for holding, moving, force transmission, torque production and transporting objects [7,11,12]. Knowledge about the way that handle features affect the use of an object or a tool is essential to improve the design of hand tool handles and consequently to reduce acute and chronic hand injuries [13]. The main contribution of ergonomics in hand tool design is focused on tool handles which interact with human hands [14,15]. As a result, ergonomic design of handles has been shown to be a basic principle in effective hand tool design [7,16–18] Ergonomically designed handles can reduce biomechanical stresses, discomfort and risk factors for MSDs and hand injuries.[11,12] There is also evidence that ergonomically designed hand tools can influence user performance [7,11]. Handle shape has been considered in a number of previous ergonomic studies as an effective feature in tool handle design [6,11,19].

Conforming to ISO standards (Standards No. 5349–1:2001 and 5349–2:2001) [44] the triaxial accelerometer was firmly mounted on the back of the dominant hand using double-sided tape. The displacement of the accelerometer while moving the joint was prevented by using medical tape (3 M™ Durapore™). It was ensured that the accelerometer did not impede the controls for using hand tool. The accelerometer for the hand positioned x-axis, i.e., the longitudinal axis of the third metacarpal bone. It was oriented parallel to the sides of the digits. The y-axis was set perpendicular to the x-axis, and parallel to an imaginary line passing through the palm in the standard anatomical hand position. The z-axis was placed perpendicular to the other two axes and directed parallel to the knuckles [44].
