Injury machines tools

Tools and machines are a major source of injuries. Hand tools cause about 8% of lost-time occupational accidents machines cause an even greater share. Because powered tools and machines involve high levels of energy and power, injuries are often more severe than for hand-operated ones. 

There are many kinds of injuries related to tools and machines. Tools and machines designed to cut materials will also cut people. Knives, hatchets, and axes are examples of cutting action hand tools. Hedge trimmers, paper cutting machines, and shears are examples of powered tools and machines. 

What kinds of injuries can tools and machines inflict ... 

Model of mechanical hazards on a numerically controlled machine tool. The model describes the typical flow of incidents, which can result in injuries to persons and in material damages. 

Amputations of exposure include powered hand tools and powered machines. Many industries have this type of injury, as do many occupations. Machine operators are the single most injured occupation for eunputations. 

X-ray technology gave physicians a powerful tool that, for the first time, permitted accurate diagnosis of a wide variety of diseases and injuries. Moreover, since x-ray machines were too cumbersome and expensive for local doctors and chnics, they had to be placed in healthcare centers or hospitals. Once there, x-ray technology essentially triggered the transformation of the hospital from a passive receptacle for the sick to an active curative institution for aU members of society. 

Based on an analysis of construction-related accidents in Kuwait city during 1996-2007, Al-Humaidi and Tan (2010) found that falls are the major type of accident (33 %) followed by being crushed or struck by a falling object (25 %), and then by use or misuse of tools (18%). Furthermore, these authors reported that almost 83 % of the victims of constmetion accidents in Kuwait sustain permanent disabilities. For United Arab Emirates (UAE), 51 % of the occupational injuries are due to falls, 15 % are due to falling objects, 11 % are due to powered machines, and 6% are due to bitms (Barss et al. 2009). 

Puncturing injuries. These injuries occur when an object penetrates straight into the body of a person and pulls straight out. Usually, in the industrial sector, these types of injuries are associated wi punching machines because they have sharp tools. 

An injury source is the principal object such as tool, machine, or equipment involved in an accident and usually the object inflicting injury or property damage. An injury source also has the names agent or agency. 

Fail-Safe Devices Fail-safe devices are safety devices designed to prevent exposure to hazards. They also prevent injury or damage when a system or machine fails. Examples of fail-safe devices are automatic fire doors, air brakes on truck trailers, a dead-man switch on powered hand tools, and safety cans with a spring-closing lid for flammable liquids. 

Being stmck by materials is another hazard for some tools and machines. When using a cold chisel or star drill and hammer to break a hole in concrete, particles of concrete fly from the tip of the tool with each blow. Particles fly from the cutting tool as a lathe removes material. The particles may strike the tool or machine user or someone else. Some parts of the body, such as the eyes, have a greater risk of injury than others when stmck by flying materials. 

Repeated motion by users operating a tool or machine can lead to a group of injuries called cumulative trauma disorders or repeated motion disorders (RMDs). 

Abrasion injuries result from contact with machines that use friction or abrasion, such as grinding and sanding equipment. Puncture wounds can result from contact with pointed tools, like drills, punches, and awls. Tissue tears and cuts may result from contact with sharp edges on equipment. 

A variety of cmshing injmies, fractures, and other injuries can result from getting caught in the compression action of a tool or machine. 

Objects may fall from machines and cmsh hands, feet or bodies. There may be poor anchoring of materials acted on by tools and machines. The materials subsequently fall, producing crushing or related injuries. 

The risk of cold injury can be minimized by proper equipment design, protective clothing, and safe work practices. For work performed below the freezing point, metal handles and bars should be covered by thermal insulating material. Also, machines and tools should be designed so that they can be operated without having to remove gloves. 

The relationship and interaction between a person and the tool, equipment or machine they are using can be very important in either being a factor in accident or injury, or in preventing accident or injury. 

A flying object hazard exists when something has been thrown, hurled, or propelled across space. It can include instances when a piece of material separates from a tool, machine, or other piece of equipment, and strikes a worker, resulting in injuries or fatality. 

The first defense in the battle to reduce hand injuries is engineering controls designed into equipment during manufacture or used to alter the work environment to make it safe and hazard free. Machine guards protect hands and fingers from moving parts and should not be altered or removed. Jobs should be designed to incorporate proper positions for tools, hands, and materials. 

The identification and the analysis of risk, and making rational decisions based on the known risk, are the best preventive management tools a maintenance workforce can use. The risk assessment will allow a company to maximize its safety program and thus reduce accidents. The risk assessment process should be formalized in order to reduce accidents that could cause injuries, death, machine damage, and longer equipment stoppage. One must learn in maintenance that one must reduce risk at all times. In any task there are risk and thus the reduction or elimination of risk will make all tasks more successful and safe.
