It is of great importance to facilitate the risk assessment process in construction projects because risk assessment is a requirement in most legislation and safety standards. A great majority of construction SMEs (Small and Medium Enterprises) are not familiar with risk assessment concepts and methods. In particular, SMEs are very likely to have difficulty finding the qualified personnel or time to carry out a proper risk assessment. The method introduced in this paper has some distinct features. The method introduces a new method of risk assessment, replacing the traditional definition of probabilities with control levels because they are easier to implement and yield more accurate risk scores. The method was practically applied on 22 construction SMEs. From the practical application, it was observed that the method was found to be user friendly and the SMEs found it easy to update their risk strategies during various construction stages in their projects. The proposed risk assessment method introduces a powerful and practical control level strategy which would develop a safer, healthier and more competitive workplace for construction SMEs.

Risk Assessment Method

Successful implementation of Health and Safety (H&S) systems requires an effective mechanism to assess risk. Existing methods focus primarily on measuring the safety aspect; the risk of an accident is determined based on the product of severity of consequence and likelihood of the incident arising. The health component, i.e., chronic harm, is more difficult to assess. Partially, this is due to both consequences and the likelihood of health issues, which may be indeterminate. There is a need to develop a quantitative risk measurement for H&S risk management and with better representation for chronic health issues. The present paper has approached this from a different direction, by adopting a public health perspective of quality of life. We have then changed the risk assessment process to accommodate this. This was then applied to a case study. The case study showed that merely including the chronic harm scales appeared to be sufficient to elicit a more detailed consideration of hazards for chronic harm. This suggests that people are not insensitive to chronic harm hazards, but benefit from having a framework in which to communicate them. A method has been devised to harmonize safety and harm risk assessments. The result was a comprehensive risk assessment method with consideration of safety accidents and chronic health issues. This has the potential to benefit industry by making chronic harm more visible and hence more preventable.

A key challenge to researchers involved with geological storage of CO2 has been to develop an appropriate methodology to assess and compare alternative CO2 injection projects on the basis of risk. Technical aspects, such as the risk of leakage and the effectiveness of the intended reservoir, clearly need to be considered, but so do less tangible aspects such as the value and safety of geological storage of CO2, and potential impacts on the community and environment.The RISQUE method has been applied and found to be an appropriate approach to deliver a transparent risk assessment process that can interface with the wider community and allow stakeholders to assess whether the CO2 injection process is safe, measurable and verifiable and whether a selected alternative delivers cost-effective greenhouse benefits.In Australia, under the GEODISC program, the approach was applied to assess the risk posed by conceptual CO2 injection projects in four selected areas: Dongara, Petrel, Gippsland and Carnarvon. The assessment derived outputs that address key project performance indicators that:are useful to compare projects;include technical, economic and community risk events;assist communication of risk to stakeholders;can be incorporated into risk management design of injection projects; andhelp identify specific areas for future research.The approach is to use quantitative techniques to characterise risk in terms of both the likelihood of identified risk events occurring (such as CO2 escape and inadequate injectivity into the storage site) and of their consequences (such as environmental damage and loss of life). The approach integrates current best practice risk assessment methods with best available information provided by an expert panel.The results clearly showed the relationships between containment and effectiveness for all of the four conceptual CO2 injection projects and indicated their acceptability with respect to two KPIs. Benefit-cost analysis showed which projects would probably be viable considering base-case economics, greenhouse benefits, and also the case after risk is taken into account. A societal risk profile was derived to compare the public safety risk posed by the injection projects with commonly accepted engineering target guidelines used for dams. The levels of amenity risk posed to the community by the projects were assessed, and their acceptability with respect to the specific KPI was evaluated.The risk assessment method and structure that was used should be applied to other potential CO2 injection sites to compare and rank their suitability, and to assist selection of the most appropriate site for any injection project. These sites can be reassessed at any time, as further information becomes available.

The issues about legislation of safety management, as well as main techniques of "risk analysis and evaluation", are widely integrated in complex production environment. From an organizational and technological point of view, it’s not easy to implement these techniques in Small and Medium Enterprises. In fact, each technique does not permit a complete and exhaustive analysis and quantification of risks. Application of aforementioned methods does allow for achievement of a wide number of benefits. The aim of this paper is to critically analyse both analysis and risk assessment processes. In this paper, integration between System Dynamics and Layers of Protection Analysis technique is provided in order to enhance results of risk management. System Dynamics shows to be very effective in evaluating interaction effect of different incidental scenarios properly identified through risk analysis technique used. System Dynamics modelling permits simulation through changes in time and feedback mechanism. This approach has been validated via testing in a plastic molding plant with a scenario of risk of a massive fire.

Need—National legislative health and safety (H&S) frameworks impose requirements but grant self-management to organisations. Consequently variability arises in management systems, and some organisations struggle to achieve successful implementation. The risk assessment process is key to the H&S management system, and could benefit from greater consistency and better external alignment with the legislative framework of the jurisdiction. Approach—The harm categories in the New Zealand (NZ) Act were adapted into a consequence scale. A non-linear scale was developed for the consequence axis to represent the disproportional nature of catastrophic harm outcomes compared to minor injuries. A hazard assessment process was devised based on systems engineering methods. Organisational decision-criteria were derived from the communications requirement in the Act, and these thresholds linked to expected treatments. Originality—A method is providing for aligning risk assessments with a national legislative framework, and integrating the technical aspects of risk assessment with the management processes. The approach also more explicitly includes recovery actions in contrast to existing methods where prevention dominates. Regarding the management aspects, it shows how thresholds may be defined relative to the legislation, to give clear expectations regarding treatment and internal communication, thereby assisting executives (‘officers’ in terms of the NZ Act) meet their duties.

Methodological Aspects

Results of the health risk (HR) assessment are needed to support decisions on safety of nanotechnologies and practical use of nanomaterials/nanoparticles (NMs/NPs), including establishment of health safety standards (HSSs). To meet these needs HR assessment’ tools are developed using the great experience in the development and application of such tools for other sources of harm (ionizing radiation, chemicals, etc.), accumulated during the last decades. The tools include methodology, computer data bases and calculation codes.Three-level’ scheme of development and application of HR assessment methodology is roposed: general, specific and simplified methods. The general method serves as a basis for development of specific methods, applicable to the concrete harm sources, for development and justification of simplified methods. In this approach the specific method consists of two parts: 1) the general HR assessment method, 2) exposure – response dependences for the harm source considered in the form of age-cause-specific death or diseases coefficients. Such structure of HR assessment methodology in its full development makes specific methods being more transparent and comparable as well as safety decisions based on HR assessment for different harm sources.The proposal is made concerning the special risk index for the risk standardization and comparison. The unified approach is developed to the establishment of the HSSs and other levels of decision-making on people safety with the use of HR risk assessment in different spheres of human activity including nanotechnology and use of NPs/NMs.

<span>The paper explains utilization of Arduino Microcontroller to automatically control level of water in a tank. From a well spelt out algorithms, flowchart was drawn, from which Codes were written and compiled on Arduino IDE. IF statements were copiously used. Proteus was used to simulate the design while the project was implemented on breadboard. Liquid Crystal Display function displays the level of water on the 16 × 2 LCD thus: Very Low, Low, High and Very High. An option of I2C LCD codes was written thus providing advantage of using only two analog input A4 and A5 pins instead of 4 to 8 pins in other configurations thereby allowing other pins dedicated for other tasks. The design recommends improvements in the area of sump control so that its low water level could disable pump thus preventing it from running dry. Protection devices like circuit breaker overload and phase failure relays are recommended in order to prolong the life of the Water pump. It is believed that the design will go in long way in educating power electronic engineers in the arts of design using Arduino; also, a mass production of the device will accentuate Small and Medium Enterprises SMEs in developing countries with its concomitant economic advantages.</span>

This paper compares the role of managerial control in Micro, Small and Medium Enterprises (MSMEs) startup in Bosnia Erzegovina, Brazil and Italy respectively in the district of Banja Luka, San Caetano and Forlì-Cesena. The main reason for this emergent topic is the survey carried out in the various countries that shows that informal controls outweighs the formal controls in the MSME and that there is a good evidence that such businesses are family owned. The most interesting result of the research was the discussion on MSMEs control system that is interwoven by the role and features of managerial control in Family Business (FB). In this regard, should we assume as empirically demonstrated in model (Fig.1) together with Greiner statements, developed by other Authors (Quinn, Cameron 1983), the general framework allow us to maintain the hypothesis that the control level in the first phases of MFB startup is low and limited to punctual check and operative one.

Risk Assessment And Management

Modern organizations have raised a need to actively and quickly react to the changes in external business environment, as well as in internal processes considering not only the present situation, but also evaluating possible changes and forecasting the future. Enterprise risk assessment and management, which is strongly related with foreseeing the uncertain future, becomes topical not only scientifically, but also practically seeking to reveal new and unique solutions. Operational risk management in small and medium enterprises, creating the largest part of value added in the whole European Union, demands a separate attention and coordinated decisions and means. The objective of the paper – to analyse the process of enterprise risk management in small and medium-sized enterprises, as well as to propose adequate risk management solutions for these companies. After performing a research, it was found out that small and medium enterprises more than big organizations require a risk management strategy and methodology, need to distinguish activity objectives and events influencing them, and they can efficiently apply a risk portfolio method to manage risk. In small and medium enterprises it is recommended to incorporate a risk management system based on COSO ERM model that can be modified depending on company needs and possibilities, turning it into less formal and structured and easily applicable.
