Text Read the text on your speciality and render it while speaking on this subject Qualification of Labour Protection Engineer

Training students of the faculty of transport, oil and gas technologies is subdivided into a number of qualifications: emergency situations, hydrodrive, transport maintenance, fire safety and equipment, spacecrafts, caterpillar and wheeled machines, labour protection and others. All the students of the faculty are mechanical engineers and deal with engineering. Engineering is the discipline and profession of applying technical and scientific knowledge in order to design and implement materials, structures, machines, devices, systems and processes that safety realize a desired objectives and meet specified criteria.

Because engineering is defined as making practical application of theoretical sciences such as physics, mathematics and chemistry, the students study these general educational subjects. Each engineer should be able to design and develop various kinds of machines, to operate it and to foresee the behaviour of equipment under specific operating conditions. To meet these needs the students study specialized subjects: strength of materials, theoretical mechanics, hydraulics, electrical engineering, details of machines, science of materials, technological processes.

Strength of materials considers resistance to various loads: bending, rupture, compression, friction, shrinkage, torsion, shear and others.

Theoretical mechanics deals with external loads – impacts of one body on the other, trajectories of their motion.

Hydraulics studies movement of fluid, gas and air in tubes and aggregates. The principles of behaviour of these constituents are implemented in such appliances, as pumps, turbines, hoses, pipes and tubes.

Electrical engineering concerns electrical equipment, appliances and the sphere connected with electric current.

Details of machines include: bearings, pistons, shafts, bars, cams, axles, cranks, crankshafts, meshes, gears, transmissions, springs and conjunction of these details.

Science of materials concerns with the types and properties of materials, metallic and non-metallic constructional materials, their behaviour under thermal, chemical and mechanical conditions and the means of their processing and finishing.

Technological processes involve the means of machining and treatment of various materials, maintenance of machines and equipment and are aimed at getting products.

The most important subjects, however, are life safety provision, labour protection and safety engineering rules. Life safety provision is the area of scientific knowledge studying the general dangers, menacing the person, and developing corresponding ways of protection against them in any conditions. The conditions are labour environment and workplace, the organization of which should base on achievements in the field of medicine, biology, chemistry, physics and other sciences. The factors negatively influencing a human body are accepted to divide into harmful and dangerous. To harmful factors belong those which become the reason of diseases or decrease in working capacity of a person. Such factors which can lead to traumas, accidents, health disorder or physical inability are called dangerous. The dangerous situation is adverse conditions in which the harmful and dangerous factors of the various nature menacing to health, human, lives, their property are acting.

To avoid accidents and health disorder in extreme situations each person should know and observe all safety rules on his workplace. The extreme situations may be noise, bad or excessive light, vibration, dust, air pollution with gases, smoke and chemical evaporations, cold or heat radiation, uncovered parts of machines, unproper uniform. It is necessary to wear safety glasses in the shop. Clothing should not be loose. Ties, scarves, belts have to be removed. Long hair should be tied up. In chemical manufactures it is necessary to wear protective uniform. Specialists in labour safety deal with labour conditions and labour productivity. They study the subject which is called ergonomics. Ergonomics is the scientific discipline studying labour processes with the aim of creating optimal labour conditions, which contribute to increasing its productivity and ensure necessary comfortable labour environment. The main concern of this science is saving health, energy and work-capacity of the people.
