All hand tools are divided into different groups. Depending on the destination, the corresponding safety requirements are imposed on the hand tool. What are the security requirements that this or that fitting and assembly tool must meet, and consider further.
Periodically it is necessary to pay attention to the play of the sliding key.
Common moments when storing and using hand tools
Manual tools that are involved in the work process, you must:
- keep in good condition;
- apply for the intended purpose;
- take only those employees who have special training and admission to work with him.
A set of hand tools: sledgehammer, hammer, chisel, chisel, file.
The entire set of plumbing tools should be inspected at least once per quarter by a specialist from the engineering and technical service who is listed at the disposal of the department.
All tools are carried in tool boxes designed for this purpose. During operation and at the time of storage at mounting and metalworking equipment, sharp edges should be equipped with protective means (caps, covers, etc.) from mechanical effects.
For the implementation of the labor process in close proximity to electrical installations and other objects that are energized, it is necessary to use insulated or non-transmissive mounting and plumbing fixtures.
For work in the immediate vicinity with flammable or explosive substances, use of assembly and fitting tools that do not form sparks should be used.Back to table of contents
Safety requirements for varieties of hand tools
The surface of the sledgehammer should be flat with a slight bulge.
In the case of manual equipment with impact, cutting and pressure type of action, the rods should consist of dried wood of hard-to-viscous varieties, without knotty and burrs. Therefore, they should have a smoothness, possible only with careful processing.
The surface of the sledge hammer with hammers should have an evenness, a slight bulge. The sledgehammers with hammers themselves must be distinguished by the reliability of the tips on the cuttings, must be wedged with wedges made of mild steel. Chisels and files should be mounted on wooden rods with metal rings.
The surface of the cutting axes should be even, without chipping, the ax handle should be mounted on a handle of a special configuration and be wedged with wedges of soft steel.
The cuttings (rods) of the shovels should be firmly fixed by the holders, the part of the rod leaving the holder should be inclined to the surface of the shovel. Suitable material for rods is dry and smooth wood of hardwood.
Pliers are recommended to provide protective rings.
Chopping and cutting devices (cores, chisels, cuts) should not be equipped with deformed and oblique heads with cracks, burrs, work hardening, splitting in the occipital region, there should be no faults on the cutting region, sharpness should not be observed on the end faces. The chisel in length should be not less than 15.0 cm, the core, the barb in length should be no more than 15.0 cm.
Using ticks, they must be supplied with protective rings to protect workers from falling parts. The dimension of the rings must match the parameters of the parts. From the inside, there should be an abutment in the pliers handles that exclude pressure on the fingers. The surface of the tick handles of metal should be different smoothness, to be free of chipping, barbs, dents.
The size of the keys of the wrenches should be the same as the parameters of the nuts and the heads of the bolts, not detecting potholes and cracks. The surface of the opening of the wrenches of wrenches should not contain wrinkled and knocked edges, there should be no burrs on the handles. It is unacceptable to use gaskets between the edges of the nuts and the surface of the key, increasing the key by connecting another key or putting pipes and other objects on them, unless the configuration of the key is provided for. Extension of the key lever is possible only for special keys for installation, which are designed for use in manipulations with an increased shoulder impact.
Sliding keys on moving parts should have a normal play, but not more than the norm.
During the work with a chisel it is necessary to put on goggles observing safety measures.
Chisels and other hand-held devices are intended for cutting metal, while workers must be equipped with safety glasses with a mesh or with durable (non-cracking) glasses.
The vice should be thoroughly attached to the workbench, so that the jaws are at the height of the working elbows. It is better to install the vice jaws in parallel, make a serif on them and check the reliability of the clamping of the product used. The vise should be placed with an interval of at least one meter between each other. In order to protect workers from flying particles, it is necessary to put mesh fences with mesh openings of no more than 0.3 cm, in height - not less than 1 meter.
Working with the tool of the shock principle of action, workers should put on goggles to exclude traumatization of eyes.
Manipulations with devices (files, scrapers, etc.), in which the rods are attached to the sharp ends without metal bondage rings, are unacceptable.
It should be properly diluted and well sharpen saws (hacksaws transverse or archery). The handles of the saws should be according to the rules and thoroughly fasten, smoothly and smoothly clean. In archery saws, the core must be distinguished by the strength, correctness of the tension of the blade.
It is important to place the fixtures in the working area according to the rules: in order to exclude the possibility of its falling or rolling.
Safety requirements prohibit placing tools on the unsecured edges of the scaffolding platform, scaffolding, on the railings of fences, near open hatches at wells.
