Hand tools maintenance

Maintenance of work equipment in good repair - from simple checks on hand tools such as loose hammer heads to specific checks on lifts and hoists. When maintenance work is carried out it should be done in safety and without risk to health. 

Each part of a press drive system requires different skills to perform the required maintenance. A full complement of hand tools and equipment, such as hydraulic jacks, heating torches, and bearing pullers, may be necessary to do the repairs. The parts of the press drive system are as follows ... 

Maintenance of an adequate amount of hand tools to accomplish daily work. 

Hand tools may include anything from axes to wrenches. The greatest hazards posed by hand tools result from misuse and improper maintenance. The employer and workers must take actions to keep tools and equipment in good working order. Employers should caution employees to keep saw blades, knives, and other tools away from aisle areas and other employees working in close proximity. The use of appropriate PPE can help protect workers against tool hazards. 

Proper use and handling of fuel-powered, pneumatic, and powder-actuated tools is also covered in Subpart I. Only employees who have been trained should operate powder-actuated tools. In addition, both power and hand tools should be maintained and serviced on a regular basis. Jacks are the last item covered under Subpart I. Proper blocking and securing of the lifted part is covered along with maintenance requirements. The standards also require the tagging of faulty or broken jacks so they will not be used by mistake. 

The statistics indicate that the minor accidents leading to 0—3 days of absence are typically caused by materials, splinters and products (FAll 2014). A typical accident of this type is a minor eye accident, caused by a splinter or fragment released during material handling (e.g. welding). Other major injury causes involve hand tools, which may cause e.g. minor cuts and bruises. In general, accidents in maintenance operations can affect any body part, and the accidents may occur at any stage of disassembly and reassembly.

Basic hand tools are the usual tools that process technicians typically use to perform their job activities (Figure 5-1). Union plants may have limitations on the type of work a process technician may perform. In these plants, the process technician may not be allowed to cross crafts and use hand tools except on a limited basis. In nonunion plants, hand tool usage plays only a minor role, as skilled craftspersons are available for complex Jobs. However, process technicians are required to perform routine maintenance on their units, since most mechanical craftspersons work the day shift and leave the evening and night shifts open for callouts. When a callout is required, the company typically pays time and a half, so it gets expensive. Also, in addition to the money issue, it takes time for the maintenance staff to return to the work site. Because of these facts, many companies require routine maintenance on the off shift(s) to be... 

Basic hand tools are the typical tools that process technicians use to perform their job activities. These include tools such as pliers, screwdrivers, wrenches, and channel locks. Process technicians are required to perform routine maintenance on their units. A little minor maintenance can often prevent major equipment damage. 

Work equipment needs to be properly maintained so that it continues to operate safely and in the way it was designed to perform. The amount of maintenance will be stipulated in the manufacturers instructions and will depend on the amount of use, the working environment and the type of equipment. High speed, high hazard machines, which are heavily used in an adverse environment like salt water, may require very frequent maintenance, whereas a simple hand tool, like a shovel, may require very little. 

Hand tools are nonpowered tools including axes, hammers, screwdrivers, wrenches. Injuries associated with hand tools most often occur with misuse or improper maintenance. 

Workers must be instructed in the correct method of use and in maintenance requirements at induction if not already included as part of craft training. All employees must be aware that they have a duty to inform their employer of any defects or deficiencies in hand tools provided for use at work. 

The service assembled 114 maintenance repair sets for chemical equipment at Edgewood Arsenal between August 1942 and July 1945. These sets consisted essentially of special tools needed for hand-tool repair of flame throwers, collective protectors, air compressors, and portable decontaminating apparatus, as well as gas mask repair tools and test equipment. No single item of field equipment supplied by the CWS proved more useful to the chemical officer in the field than did this set. 

On setting out on the planned maintenance route, if the percentage of the work to be carried out under the plan is not sufficient (say, 80 per cent), the department will continue to operate as before (i.e. firefighting) with the control of that department being in the hands of others. Any planned maintenance system is a tool. It cannot do the work itself but, employed correctly, the sound management results will prove that the efforts involved in setting up the system were worthwhile. 

The number of references has been purposely kept small in the hope that they will be actually consulted. However, there is an enormous amount of material available bearing on the theory of molecular electronic structure and applications of various models to specific cases, There is, on the other hand, a very much smaller literature on the actual implementation of the methods. Generally speaking, literature on the use of modern software tools in the generation and maintenance of quantum chemistry software is rather thin on the ground. 

This section describes the required guarding, inspections, and maintenance requirements for hand and portable tools. It includes tools employees may own and use on the job. Lawn mowers and other internal-combustion-engine-powered machines are included in this section. The proper procedures for using portable jacks are also covered in this section. 

The dermatitis may also spread to other areas of the body via hands and contaminated tools, masks, gloves and clothes or shoes. Especially in spray painting, the face and other skin areas of airborne contact are affected. In modern paint factories where the manufacturing processes are automated, only a few workers are at risk of contracting dermatitis, e.g., workers in laboratories and chemical stores, workers who take samples and perform canning, as well as the repair and maintenance personnel of the process. 

Hand and power tools Purchasing standards, inspection, storage, repair, types, maintenance, grounding, use and handling. 

A punching press similar to those used in the processing of rigid boards could be used for the blanking of flex circnits. Smaller tons are required to cut thin materials. Steel rule dies are the specialty for flex circuits (see Fig. 63.33). They can be prepared in a few days, and their costs are much smaller than those of hard tools. Their weight is also much smaller than that of hard tools and operators can manage them by hand. A typical cross section is shown in Fig. 63.33(a), a finished steel mle die is shown in Fig. 63.33(b), and some limitations on the configurations that can be used are illustrated in Fig. 63.33(c). Steel rule dies have less dimensional accnracy, lower productivity, and a shorter life than hard tools, and they need maintenance more frequently. 

In addition to the fixed installation, all other electrical equipment and apparatus used on the site should be included in the preventive maintenance programme. This will included portable electrical tools, handlamps, lighting equipment and so on. By far the most important element of this maintenance is a routine visual examination of the equipment, which will detect most faults that can lead to danger. These examinations should be carried out as pre-use user checks and then periodically as part of a formal visual inspection, typically at a frequency of once every week for 230 V hand-held equipment and extension leads, and monthly for 110 V equipment and fixed 230/400 V equipment. Guidance on the frequency of these examinations, and the frequency of tests aimed at detecting defects, is published in HSE s Guidance Note HS(G)141 and the lEE s Code of practice for in-service inspection and testing of electrical equipment.
