Fixed machinery hazards

Relationship between person, machine, environment, work methods and materials 

The relationship between a person, machine and the working environment forms an important consideration in a work system, as we noted earlier in this book. 

The work process and system are linked together by procedures that are adopted to actually perform tasks. Materials used may also be important. The relationship of the work process to the work system is represented in Fig. 7.2, as first seen in Chapter 1. 

As can be seen, the work process is reliant on the five parts of this relationship being effective and efficient. The interface, or linking, between these factors can be disrupted if compromises in safety occur. Poor linking of the factors can, on the other side of the coin, compromise safety. 

Contact between people and the moving parts of machinery often results in some of the most serious forms of industrial injury. The earliest advances in injury prevention dealt with the hazards associated with overhead transmission shafts. The transmission shaft involved that part of the power source which provided motion to the actual operational

Is fixed machinery provided with appropriate safety guards to prevent injuries to the operator and other employees resulting from point of operation, ingoing nip point, rotating parts, flying chip, and spark hazards ... 

Fixed water spray systems are most commonly used to protect flammable liquid and gas vessels, piping and equipment, process structures and equipment, electrical equipment such as transformers, oil switches, rotating electrical machinery, and openings through which conveyors pass. The type of water spray will depend on the nature of the hazard and the purpose for which the protection is provided. 

Devices used to protect the head from injury. These include safety helmets or hard hats that are primarily used to protect the head from falling objects or overhead hazards industrial scalp protectors such as bump caps that protect against striking fixed objects, scalping, or entanglement and caps and hair nets, which are used to prevent the hair from coming in contact with moving machinery or the parts of machinery. 

Are body positions, machinery, pits or holes, and/or hazardous operations adequately guarded Are fixed objects in the area whose location and design may cause injury, from sharp edges, location, or shape ...
