Abstract: In the conditions of train movement and shunting work, train compilers are exposed to great danger, which

increases when trains move forward, as well as in the case of a mismatch of physical and mental fitness,

shunting masters have a dangerous state in their work, which, due to insufficient qualities of human movement,

can lead to dangerous cases, while increasing the likelihood of accidents involving occupational injuries of

various kinds. This article presents the results of a survey conducted to determine and study the causes of

injuries among the shunting masters of the Khamza station of the Tashkent Regional Railway Junction.

1 INTRODUCTION

The workplaces of shunting masters are located inside

the rail track or in the immediate vicinity of it and on

the rolling stock (Instructions, Republic of

Uzbekistan; Rules of technical operation, Republic of

Uzbekistan.). In conditions of train movement and

shunting work, these persons are exposed to great

danger, which increases when trains move forward

with wagons (Zhukov, 2014; Evseeva, 2002;

Kaptsov, 2000). It is known that the causes of injuries

are conditionally divided into objective and

subjective (Vilk, 2001). For example, intense noises

muffle warning signals; lack of training of workers in

safe working methods; discrepancy between the

qualifications and health status of the worker to the

work performed by him; performing complex and

dangerous operations without the participation of the

work manager; low labor discipline; unsatisfactory

quality (or absence) of workwear, shoes and personal

protective equipment; violation of work and rest

regime; insufficient and irrational lighting of

workplaces and station tracks; unfavorable

meteorological conditions (low temperature, wind,

precipitation, blizzard, etc.); noise that drowns out

warning signals about danger; short-term

unreasonably increased labor intensity; absence or

unsatisfactory condition of welfare spaces. The

https://orcid.org/0000-0003-0396-4043

subjective reasons are: carelessness (mind-

wandering, distraction, etc.), unsatisfactory quality of

movement (muscle strength, speed, agility, flexibility

and efficiency) of the shunting master (Zhukov, 2014;

Vilk, 2001; Kaskov, 2006), the presence of various

phobias (agoraphobia, acrophobia, aichmophobia,

acoustic phobia, amatophobia, claustrophobia,

nyctophobia, etc.), fatigue, awkwardness

(Sulaimanov, 2021a; Suleymanov, 2021b;

Suleymanov, 2021c). With careful analysis, usually

the presence of objective reasons from the shunting

master requires a quick response in the course of work

to evolving, changing situations (Suleymanov,

2021c; Sulaymanov, 2021d; Sulaymanov, 2019). In

the case of a discrepancy between the physical

(Resolution of the Cabinet of Ministers of the

Republic of Uzbekistan, 2019) and mental

preparedness of the shunting master, a dangerous

state occurs in work, which, due to insufficient

qualities of human movement, can lead to dangerous

cases, while increasing the likelihood of accidents

with occupational injuries of various kinds (Kopeikin,

2011; Sulaimanov, 2021).

2 MAIN PART

To determine or study the causes of injuries among

shunting masters, a survey was conducted among the

shunters of the Khamza station of the Tashkent

Regional Railway Junction. The following questions

were included in the questionnaires (Sulaymanov,

2019):

1. Have you been injured in the course of your

work;

2. In what circumstances did the occupational

injury occur;

3. Do you know the cause of the injury;

4. Which part or organ of your body has been

injured;

5. Do you know what kind of injury you received;

6. After how many days did you return to work;

7. How and who chooses special footwear;

8. What personal protective equipment do you

use;

9. How to choose gloves and their material;

10. Dimensions of stair handrail (diameter, shape,

surface roughness, etc.);

11. Dimensions of the ladder tread (width, length,

material, surface roughness);

12. Dimensions and indicators of brake shoe

(handle dimeter, weight, etc.);

13. Does the shunter need a radiotelephone;

14. What are the disadvantages of the shunter's

workwear;

15. What are the suggestions for reducing

occupational injuries;

16. What suggestions are there to improve the

working conditions of the shunter;

Histograms are constructed based on the data

obtained after their processing (Fig. 1-16).

The analysis of the obtained results shows that

18% of shunting masters with 5 or more years of

experience received various injuries. Injuries to

various limbs (upper and lower) mainly occurred

when falling from the steps of the car (30%), while

climbing the steps of the car (25%), while crossing

the railway track and descending from the steps of the

car (18%). The causes of injury are considered by

shunting masters to be 50% to 50%. The knee joint

(67%), elbow and head (33%) were mostly injured in

all the surveyed shunters. The resulting injuries lead

to 25% strained muscles, bone fracture of the upper

and lower limbs, head injury, etc. 68% injuries of

shunting masters lead to the temporary incapacitation

from 7 days to 1 month and are moderate injuries.

Considering that, 50% of the injury is due to slippery

steps of cars. The question of who and how chooses

the special footwear of the shunting master was

studied, and it was revealed that 67% of the shunters

do not know how to choose shoes taking into account

the sole material in order to prevent slipping when

walking on the steps. 67% of shunting masters do not

use personal protective equipment for individual parts

of the human body (knee pads, elbow pads and hard

helmets), the materials of gloves by the value of their

sliding coefficient on metal handrails does not allow

strong fixation of hands. According to the survey

materials, the dimensions of the handrail (diameter,

shape, surface roughness, etc.) are not convenient for

moving up stairs, ramps and for reliable fixation of

the human body on the steps of freight cars when it

moves. All the shunting masters surveyed consider

shoes not comfortable and heavy, as well as 20% of

shunters consider radiotelephones unnecessary and

interfere with work. 50% of the shunters consider

glove materials slippery and, in their opinion, special

clothing wears out quickly, the soles of shoes are

slippery and not convenient to work with. According

to the results of surveys, shunting masters propose to

improve the design of stairs, steps, handles, to

develop norms and requirements for the shunter's

workwear. In addition, it is proposed to normalize

sanitary and hygienic working conditions (Kaskov,

2006) (fig. 1-3).

3 CONCLUSIONS

In general, the results of studying the causes of

injuries among shunting masters showed that they are

injured due to a fall when descending from a moving

car, due to the lack of development of movement

qualities and non-compliance of the basic physical

and mechanical indicators of special clothing and

shoes. In addition, the causes of injuries to shunting

masters may be various phobias that individuals who

work as shunting masters have (Evseeva, 2002;

Kaptsov, 2000; Sulaymanov, 2021d). In order to

eliminate the causes of injuries among shunting

masters associated with physical inconsistencies in

human motor qualities (speed, strength, agility,

flexibility, efficiency) (Sulaimanov, 2021) and the

stability of psychology to various phobias generated

by working conditions, it is necessary to develop a

methodology for assessing the professional suitability

of shunting masters for high-quality professional

selection (Kaptsov, 2000; Kaskov, 2006). High-

quality professional selection of the shunting master

will significantly reduce the likelihood of accidents at

work.
