Abstract

Purpose

The manufacturing industry perceives government standards as an attempt to unnecessarily increase production cost. This may be due to lack of acceptable models for demonstrating the associated benefits to industry. It was the goal of this study to develop a simulation model for predicting the performance of a manufacturing safety programme (SP).

Design/methodology/approach

The principles of system‐dynamics were applied to identify the relevant safety‐related components and their relationships. A simulation model for evaluating periodic performance of a manufacturing SP was then developed. A set a dynamic equations for predicting factory accidents or preventions and the monetary saving were the performance measures. Two set of factory data: non‐SP (1979) and SP (1991‐2004) were collected from a bottling company. The parameters of the model were estimated using the first set while it was validated with the second and associated monetary saving computed.

Findings

Solutions to factory accidents or preventions yielded exponential functions. The means and standard deviations of the predicted and actual accidents were 32 and 5.66; and 30 and 7.46, respectively. The corresponding values for predicted and actual preventions were 55 and 10.47; and 59 and 7.45, respectively. There were no significant differences between the predicted and actual for the accidents and preventions, respectively, at 5 per cent level. The predicted SP saving per annum was 6.96 millions.

Originality/value

The model is a useful tool for setting profitable manufacturing safety standards and effective SP management.

Abstract

Purpose

Managing a safety programme and ensuring that change is in accordance with suitable performance measures requires continuing improvement in the support of analytical power and empirical information. This paper aims to consider different approaches and modeling efforts on safety performance evaluation.

Design/methodology/approach

Review and synthesis of literature.

Findings

Ten major safety performance evaluation approaches are identified including expectation function, risk assessment, statistical quality control, price deflation, engineering economic factor, system analysis, artificial intelligence, and systems theory. Based on the approaches, quantitative and qualitative models have been proposed. The quantitative models use measuring indicators such as frequency, severity, percentages, relative weight and economic gains/loss of safety programme. However, qualitative models employ hazard analysis and hazard operability.

Research limitations/implications

Several research questions remain to be answered in order to completely improve and optimize the impact of these provisional safety performance measures.

Originality/value

This study offers a set of interesting lessons for academics, industry and safety practitioners by providing guidelines that will assist in ensuring a correct focus to select an appropriate safety performance evaluation model.

Abstract

Purpose

The cheapest and most rapidly available metal for agro‐processing equipment fabrication in Nigeria is plain carbon steel. However, there are some aggressive ions present in raw agricultural and food products, which may attack the steel components of these processing machinery, resulting in their untimely failure in service. The present study investigates the effect of fluid squeezed from cassava tuber on the corrosion behaviour of mild steel.

Design/methodology/approach

The investigation involved periodic weight loss measurements of 0.8 per cent carbon and 0.36 per cent carbon steel rods as they were exposed to cassava fluid. The relationships between loss in weight of the exposed samples and exposure period were determined. Models were developed to relate corrosion rate in each environment with total surface area and exposure period.

Findings

The results show that 0.36 per cent carbon steel was less affected by corrosion than 0.18 per cent carbon steel, with corrosion intensity in both cases, increasing with duration of immersion. Generally, there was low level of corrosion resistance (high corrosion rate) by the two steel materials. The correlation coefficient between the experimental values of corrosion rates and predicted values (using the developed models) was high.

Originality/value

In food and agricultural industries, product quality, health and sanitation issues are the major concerns. The industries cannot tolerate corrosion deposits in the manufactured products. Hence, material selection for machinery fabrication is essential. In line with this, the results of this study indicate that mild steel materials are unsuitable for use in cassava processing without some forms of surface treatment.

Abstract

Purpose

The purpose of this paper is to employ a system dynamics approach to develop a mathematical model for managing magnitude and risk factors of injuries in a manufacturing industry. This is to provide the decision makers with a systemic‐strategy to capture the transition of industries, especially manufacturing, into world‐class safe workplaces.

Design/methodology/approach

An accident investigation register was administered to capture needed data to estimate the model parameters and identify risk factors of injuries. The principle of system dynamics (SD) was employed to identify the relevant safety‐related components and their interrelationships. Applying the concept of causality analysis, causal loop and SD flow diagrams indicating how prevention activities may eliminate hazardous conditions were delineated and a mathematical model to predict the main variables involved in manufacturing safety programme was formulated.

Findings

The validity of the model was demonstrated using the observed data from accident investigation and register review; and a satisfactory agreement was found between the observed data and the model predictions.

Practical implications

The proposed model's attribute of predicting the probability of injuries or preventions is remarkable and thus, useful for managing sustainable safety control programmes.

Originality/value

This paper presents a manufacturing safety programme using equation‐oriented technique to predict the main variables required for managing magnitude and risk factors of injuries in a manufacturing plant.

Abstract

Purpose

This paper aims to investigate the safety practices in some selected agro‐allied industries in south‐western Nigeria with a view to analysing the degree of safety awareness; adequacy of safety equipment; extent of enforcing safety rules; effectiveness of safety‐related activities and economics of safety programme.

Design/methodology/approach

A case study method of investigation, field study guidelines and binary variable were used and information gathered from 36 industries was documented. The data collected were analysed using mean, percentage and standard mathematical models. The analyses carried out on the data gathered are presented on the following: occurrence of accidents, causes of accidents, damages resulting from accidents, accident prevention activities and economic implications.

Findings

Three classes of accidents are identified as fatal, serious, and minor. The results showed that minor accident has the highest frequency of occurrence of 304, while fatal accident has the least frequency of occurrence of 17. However, serious accident has the greatest economic implication, accounting for annual average loss of $4.97 millions. Also, nine causes of accidents are identified, out of which faulty equipment is common to all industries. And eight accident prevention activities are identified, amongst which standard operating procedure, good housekeeping and on‐the‐job training are commonly being practised, while provision of safety handbook and policy is least practised.

Originality/value

This paper has described the safety practices in 15 agro‐allied industries with an organised safety programme in South Western Nigeria. The study has investigated the extent of enforcement of safety rules; safety awareness; and economic implication of accidents from this sector for the national economy.

Abstract

Purpose

The purpose of this paper is to investigate tractor maintenance practices and costs in Nigeria with a view to making replacement decisions and for overall farm budgeting.

Design/methodology/approach

The information was obtained via a structured questionnaire. Tractor owners were grouped into three categories: government agricultural settlements, established farms, and individual farms. Data used for analysis were collected from 60 farms located in major farming centers of the southwestern part of Nigeria. The report includes the formulation of repair equations, which relate tractor repair cost as a percentage of initial purchase prices to cumulative hours of use. Life cycle costs of three commonly‐used tractors were also estimated. The derived equations, which showed that the repair costs per hour increased with hours of use, were used to obtain the life cycle cost of each tractor model in different tractor owners' farms.

Findings

The proposed equation was found to be the best fit with coefficient of determination (R2) ranging from 0.992 to 0.996 for tractors in the three user categories. The trend observed in the life cycle costing of the three common tractors gave the general picture of when to replace each of the tractors based on the strategies being adopted by the tractor owners.

Practical implications

The results of this study would serve as baseline information to tractor owners regarding optimum use of tractors for minimizing repair and maintenance cost per hour and for making replacement policy. It would also be helpful to government and other agencies for future planning in the provision of tractor services to the farmers at relatively lower repair and maintenance cost.

Originality/value

Proves that a reduction in repair costs by careful operation and adequate maintenance could result in a significant reduction in tractor ownership costs.

Abstract

Purpose

The manufacturing industry in Nigeria often perceives government safety standards as an attempt to increase production cost. This is due to lack of acceptable template for setting an attainable standards and safety programme to the manufacturing industry. It is the goal of this work to develop such a template for an effective and sustainable manufacturing safety programme.

Design/methodology/approach

A total of 30 manufacturing firms were examined and five experienced manufacturing, and three safety engineers interviewed for information on types of SP activities. Review and synthesis of literature was carried out.

Findings

Four types of accidents are identified as fatal, serious, minor and trivial wounds. Accidents causing factors are classified into human factor, deficient maintenance of facilities and environmental factors. The prevention activities were categorized into training, guarding, awareness, incentive, accident investigation and personal protective equipment (PPE).

Practical implications

This study provides baseline information for academics, industry and safety practioners to setting an attainable and effective manufacturing safety programme.

Originality/value

The paper suggests a mathematical approach for developing a manufacturing safety programme.

Abstract

Purpose

Agriculture remains the largest sector of Nigerian economy, generating employment for about 70 per cent of the population. With the ever‐increasing market demand for agricultural products, mechanisation of most farm operations is gradually on the increase. This new development has brought about an increase in the cases of accidents through the use of farm tractors.

Design/methodology/approach

This study was carried out in the south‐western part of Nigeria to investigate the safety measurement, effectiveness, and its contributions to farm tractor usage in the State. The study identified various causes of farm tractor accidents, consequences and different classes of farm tractor‐related accidents. The effectiveness of each accident prevention method and frequency of use were investigated and put into consideration in the data analysis.

Findings

It was revealed through the analysis that the use of safety protective wear gave the highest contribution (24.05 per cent) to total accident prevention on farms while the use of orientation training and seminars gave the least contribution (8.30 per cent) with the lowest frequency of use than the other methods.

Practical implications

The results of this study serve as baseline information for tractor manufacturers regarding the inclusion of certain parts in new or proposed tractor designs with particular peculiarity to Nigerian farmers.

Originality/value

This paper gives an estimation of the magnitude of farm tractor accidents in relation to the Nigerian farming situation and proposes remedial actions.

Abstract

Purpose

The purpose of this paper is to identify the facilities maintenance employees’ priority on safety management practices and relationship to safety performance. The study aims to increase the safety performance among the facilities maintenance contractor by implementing safety management practices.

Design/methodology/approach

The data were collected by distributing questionnaire forms to the employees of selected facilities maintenance contractors representing general workers, technicians and executive- and the management-level employees. Data were analysed using descriptive statistics, t-test, one-way analysis of variance, Pearson correlation and multiple regressions.

Findings

The descriptive results revealed that the employee priority on safety management practices is fairly “low”. The correlation and regression analyses tested and satisfied that management commitment, workers involvement in safety, safety training, safety communication and feedback, safety rules and procedures, and safety promotion policies significantly and strongly correlate with the degree and level of satisfaction to the safety performance.

Research limitations/implications

This research focuses only on facilities maintenance contractors working in the Klang Valley, Malaysia. It is possible that respondents from other areas or states may allow comparisons across different locations.

Practical implications

There are many factors affecting safety performance. By implementing safety management practices, high safety performance can be achieved in the facilities maintenance organisations in Malaysia.

Originality/value

This paper presents empirical findings on the relationship between employee priority on safety management practices elements and safety performance.

Abstract

Purpose

Catastrophic failures in high-reliability installations result from technical and human factors. The purpose of this paper is to use reports of the BP Texas refinery accident and the UK Buncefield oil storage explosions as the basis for exploring how protection and safety are managed in high-reliability manufacturing organisations in South Africa.

Design/methodology/approach

A survey of 21 high-reliability firms was undertaken to establish how firms perceived their safety and protection systems in relation to the findings of the Buncefield and BP Texas accidents. Interviews were held with staff in two firms.

Findings

The study identifies technical and behavioural shortcomings in managing safety and protective systems in manufacturing organisations. There are profound differences in perceptions of managers, supervisors and operators regarding a number of safety-related factors. Firms fail to identify all protective systems. Essential failure data for determining appropriate policies for failure finding are not collected.

Research limitations/implications

Quantitative results are based on a relatively small sample and qualitative perspectives derive from two case studies.

Practical implications

Managers are unsure how protective devices should be managed. The paper highlights areas where significant improvements are essential if the South African firms are to meet developed world standards.

Social implications

High-reliability organisations are obliged to minimise the possibility of serious incidents whose consequences may extend far beyond the physical bounds of the organisation.

Originality/value

Limited research has been published on the management of protective systems. This paper highlights a number of technical and behavioural issues that should be addressed for safe operation of high-reliability manufacturing organisations.
