This study aims to find work concepts and mesoergonomic stages that are not well known and are not widely used in solving problems related to ergonomics using macro and micro ergonomics.

The study used a questionnaire distributed to several ergonomists who were able to provide opinions on meso ergonomics, especially in determining what aspects affected meso ergonomics so that the meso stages could be determined.

The results of data collection show that aspects that affect meso ergonomics are closely related to macro and micro ergonomics, aspects that are found to have similarities between the three because meso ergonomics is between them.

Determine the stages of meso ergonomics and clarify the limits of meso ergonomics using a questionnaire distributed to several respondents who understand ergonomics.

This paper can be applied to organizations that have a tiered organizational structure so that departments in the organization are divided into several parts to be observed and related to each other in carrying out organizational functions.

Provides convenience for researchers in observing organizations with the presence of mesoergonomics which is a bridge between macro and micro ergonomics.

The stages of meso ergonomics are arranged based on aspects and meso ergonomics variables that have been obtained from previous studies which now have added some considerations in the preparation of mesoergonomic stages such as the macroergonomic analysis design on macro ergonomics.

To investigate safety at truck drivers' work outside the cab with a special focus on work environment and equipment maintenance to prevent occupational accidents.

Two statistical databases on Finnish occupational accidents for truck drivers are analysed. Firstly, the national accident statistics database is examined to understand the broad context, and secondly a database on fatal accidents is analysed to better understand the root causes of the accidents and their relationship to human factors in maintenance. Based on the root cause analysis, four accident scenarios are created, and risk management measures are prioritized by occupational safety and health specialists (n = 7).

The study shows that there are a variety of accidents in truck drivers' work. Most of the accidents occur outside the cab while performing tasks other than driving. Further, in-depth analysis of the fatal accidents increases understanding of the possibilities of different risk management and maintenance actions in preventing such accidents.

Databases contain different limitations concerning the data.

Truck drivers' work environments are wide in nature. Efficient safety management requires broad participation from different stakeholders. In addition to safe work activities, work environment and equipment maintenance is highlighted as a key component for safe and fluent delivery transportation.

Road transportation forms a backbone of modern society. Accidents affect the efficiency of transportation and cause manifold costs reaching all the way to the societal level.

This study adds an important dimension of delivery transportation to a current scientific discussion on human factors and maintenance.

The purpose of this paper is to identify various individual factors and combinations thereof that can contribute to truck drivers’ occupational accidents, particularly connected to work performed outside the cab in various work environments.

In total, 74 accidents were analysed through in-depth interviews with truck drivers. These interviews were conducted employing the critical incident technique, and analysed utilising a qualitative content analysis approach.

The contributing factors identified were categorised into 14 categories. In all, 13 of these were grouped into four sections reflecting the drivers’ work outside the cab: “Goods and equipment”, “Loading/unloading area”, “Loading/unloading tasks”, and “Organisation”. A single risk factor was associated with 40 accidents while the other 34 involved combinations of factors.

Although the tasks performed by truck drivers in different countries are probably similar, one limitation might be that all the accidents characterised occurred in one country: Sweden.

The findings reveal that complex combinations of risk factors often contribute to accidents. In addition to the transportation company itself, other stakeholders, such as clients, and designers and manufacturers of technology, may influence the occupational safety of truck drivers. Different stakeholders who could contribute to managerial decision making that is designed to prevent accidents are identified and discussed.

This investigation contributes to an in-depth understanding of the causes of accidents in the transportation industry. The findings are discussed from the perspective of the stakeholders and safety management in an attempt to identify key stakeholders who can improve accident prevention.
