Identification and assessment risks in maintenance operations
(Emerald Group Publishing Limited, 2014) Wijeratne, WMPU; Perera, BAKS; De Silva, L
Purpose – The purpose of this paper is to identify the risks and methods for their assessment in the case of maintenance activities in Sri Lanka. The main objectives were to identify the occupational risks in maintenance work and the risk assessment methods in place and their drawbacks in the Sri Lankan context. Design/methodology/approach – The identification and assessment of risks were undertaken through a study of three fast-moving consumer products manufacturing organisations. The relevant data were collected through personal interviews and site visits. Findings – Most typical risks associated with maintenance are cuts, slips and falls, with severe or fatal injuries as the result of negligence of SOP and failure to use the PPE. Checklists, brainstorming and decomposition techniques were identified as the preferred methods in maintenance for risk identification while a risk rating matrix is used for risk analysis. Lack of awareness and indifference towards risk assessment; make effective risk assessment very difficult. These drawbacks can be minimised by education, systematic training and enforcing rules, regulations and procedures for controlling risks. Originality/value – Studies on maintenance worldwide have identified several maintenance-specific risks such as working at heights, the pressure of time, etc. However, there is a dearth of published research on risks and risk assessment methods in maintenance in Sri Lankan context. The findings highlighted the safety risks and risk assessment tools entailed in the maintenance operations of manufacturing organisations. The findings will be useful for those in maintenance operations in managing risks effectively through designing work environments that are risk-free.

Risk and risk assessment methods in industrial maintenance in sri lanka
Wijeratne, WMPU; Perera, BAKS; De Silva, ML
Studies on industrial maintenance operations worldwide have identified several maintenance specific risks such as working at heights, the pressure of time, etc. However, there is a dearth of published research on risks and risk assessment methods in industrial maintenance in the case of Sri Lanka. This study therefore aims at identifying the risks and risk assessment methods in industrial maintenance in Sri Lanka. The main objectives of the study were to identify the occupational risks and safety issues in maintenance work and the risk assessment methods in place in the Sri Lankan context. This was undertaken through a study of three manufacturing organisations which are involved in producing fastmoving consumer products. According to the findings, the risks which affect maintenance work can be categorised as organisational risks, unsafe acts and local workplace risks. The findings indicate that the most typical risks associated with maintenance are cuts, slips and falls, with severe or fatal injuries the result of worker disregard for standard operating procedures and/or failure to use the protective equipment provided. It was also found that check lists, brainstorming, and decomposition techniques are the preferred methods in maintenance for risk identification while a risk-rating matrix is used for risk analysis. The findings of the study highlight the safety risks entailed in the maintenance operations of manufacturing organisations and the risk assessment tools used in identifying the risks. The findings of the research will be useful for those in industrial maintenance operations for the purpose of managing risks effectively by designing work environments that are risk-fee and for educating workers on the importance of paying due attention to risks and the need to follow instructions that are in place on safety procedures in the workplace.

Risk management in electrical distribution system in Sri Lanka hotel industry
Wanigasinghe, PC; Parera, BAKS; Wijeratne, WMPU
An uninterrupted service throughout the facility is a must for building services in the hotel industry because a large part of guest satisfaction with the hotel depends on building services. However, building services face many different types of failures due to various risk factors. Therefore, a risk management framework is an essential part of the building services of a hotel. In case of hotel buildings, the literature suggests electrical power distribution system (EPDS) to be the key building service which governs all other building services and failure in the EPDS can happen due to maintenance risks, operational risks, assets specific risks and human errors. This research was commenced through a study of three leading five star hotels in Sri Lanka. Based on the research findings, a risk management framework was developed to address risks in EPDS of a hotel facility. The risk management framework was developed based on these findings reveals effective practices that could be used to reduce failure in EPDS. The research also pointed that maintenance risk, unplanned operational risk, asset-specific risk and human errors as the main internal risk factors that lead to failures in EPDS. On the other hand, weather conditions was identified as the uncontrollable external risk factors in the hotel industry, a preventive and a predictive maintenance schedule, planned operations, training and development, and proper asset selection criteria were identified as the main risk management strategies used in the hotel industry. The paper proposed a risk management framework to overcome the identified risks in EPDS in hotel industry which consist of failure mode effect analysis, power monitoring panel and a risk mitigation plan to maintain continuous operations in the EPDS. The findings and recommendations of the study will be useful to those responsible for EPDS operations in the hotel industry for the purpose of reducing services failures.
