Abstract: Safety is very important in every workplace, but very often we hear about accidents in factories industries causing loss of life. The labours and workers working in any factory, industries, construction site or mine is vulnerable to accidents and therefore they should be with safety guards properly. In most of the accidents, number of deaths or severe injuries is maximized because the labours and worker are not wearing safety equipmentor wearing low grade safety equipment. Working environment hazards include radiation leakage, fall due to suffocation, poisoning gas leakage and gas explosion. Hence air quality and hazardous event detection is very important factorin industry. In order to achieve those safety measures, the proposed system provides wireless sensors network for monitoring real time situation of working environment from monitoring station.

4,4′-Methylenedianiline (MDA) is a chemical used in manufacturing and insulation processes and is a well-known hepatotoxin. We report the case of a 42-year-old construction-site worker who was accidentally exposed to large amounts of MDA and developed acute liver damage. The clinical course is described, with particular emphasis on the timely identification of the underlying cause and prompt management that led to an uneventful recovery. We review the relevant literature and discuss the safety measures necessary to minimize similar occupational hazards in industrial workers.

Mechanical dry gas seal systems were retrofitted into two centrifugal natural gas compressors which are located offshore in the Norwegian sector of the North Sea. The project was initiated after a fire and several gas explosions had occurred in the gas turbine lube oil reservoir. These incidents were a result of gas leaking from the compressor’s seal oil system and then migrating via the lube oil lines into the reservoir. The dry gas seal systems have eliminated gas leakage into the turbine lube oil reservoir, eliminating the hazard of gas explosion. The retrofits have also provided additional benefits including reductions in space and weight, reduced power usage, reduced maintenance, and elimination of seal oil consumption which had been up to 440 gal./day (2000 liters/day).

Areas Of Interest

Gas-explosion events in the private or industrial field are usually followed by a technical analysis of the factors that led to their generation. In this respect, INCD INSEMEX Petroşani is accredited for conducting the technical expertise and for the elaboration of the Expertise Report. Starting with on-site findings and sampling, research continues at INCD INSEMEX laboratories, grouped on areas of interest in case management (electrical, ventilation, chemical, pyrotechnics, etc.). Determining the causes of the event implicitly involves establishing the probable source of initiation of the explosive mixture, after discovering the fuel gas source and analyzing how the mixture was formed. Due to the geometric complexity of the space in which the explosion occurred, incident, reflected or compound shock waves generated by explosion can create a footprint of the event that questions the location of the source of initiation. Depending on the possible sources found in the field, the INSEMEX Laboratory of Computational Simulations performs analyzes based on finite elements and finite volumes methods. The elements taken into account in the computational simulations concern both the geometry of the space, the nature of the combustible gas leakage, the dispersion of the gas, and the resulting thermal and mechanical effects.

The project focuses on the employability of construction site managers since they belong to a much imperiled occupational group. Next to the impairment of health of the individual, the missing work time leads to a huge impact on the economy. Reducing the average missing work time about half a day would increase the annual production about 1.87 billion Euro. On this background the protection of employability and the avoidance of missing work time has to be the goal. The analysis of the current state was performed by different methods, i.e., online surveys, interviewing experts and recording processes on construction sites. The results of the analysis showed that construction managers are happy about their profession and that they like their job. But the results also showed that construction managers wish for a better balance between leisure and working time. A Construction Site Manager’s current working environment is molded by many challenges including: computerization, speedy development of new technology, acceleration, juridification and economization. Based on the survey the Pentagon of construction management was developed with the focus on improvement. Improvement can be in the form of practical aids, tools-such as the qualification matrix or the application for interface analysis and process optimization. Also a new concepts like the assistance of construction management. For which a modular qualification system was settled, which can be used for dual studies, as well as in a form of postgraduate education.

The article presents results of the granulometric composition of chip particles when sanding wood (beech) and wood-based materials (particleboard and semi-hardboard) using different types of sanders – wide belt sander, narrow belt sander, and hand sander. On the basis of the carried out sieve analyses, the proportion of produced particles, which can be marked as dust with the particle size of ≤ 80 μm, is high at the interval from 89.21% - 96.29 %. The highest percentage of dust particles was reached at dust from the hand disk sander. At the end of the article we point to possible technical safety measures – additional dust exhausting, suction, to possibly reduce the dust getting to the working environment.

All users of sea transportation in Indonesia in particular and in the world in general, place great importance on safety and security issues. They are vital to avoid accidents which can include the sinking or burning of ships, collisions and running aground. The causes of accidents can be broken down into three groups: human factors; technical factors; and weather factors. These can result in loss of life, psychological trauma to survivors, material losses, and environmental damage. This study proposes the following as key considerations in the reduction of accidents: the provision of safe practice guidelines; identify and introduce protections for all risk categories; continuously improve onboard and personal safety measures. In addition, measures can be taken to mitigate the impact of accidents after they occur, such as responsivity, the collection of evidence to establish why accidents occur and ensure they do not occur again, good leadership and demeanors from ship personnel.

The construction industry plays a prominent part in the progress of a country socially and economically. Nowadays construction industry has grown profit driven and the management focuses more on completing the projects on time neglecting safety of the workers. Construction works involving intricate works leading to accidents or injuries resulting in loss of life and body parts are rampant. So a proper safety management system is required to avoid accidents and improve safety at construction sites. Factors affecting safety at construction workplaces were identified and was surveyed through a quantitative questionnaire and analysed to form a basis for the total construction safety management model. The Total Construction Safety Management (TCSM) based on the PDCA modelling is proposed to improve safety at construction sites. This model can act as a guide to the present organizations and helps them to implement safety in quicker manner at construction site.
