Indoor and outdoor coverage of the tetra radio communication networkin Belgium
(Vysoká škola báňská - Technická univerzita Ostrava, 2012) Voorde, Christian van de
Indoor and outdoor radio communication coverage is permanent issues for the emergency services in every country. In earlier times, every local service had its own communication network. Modern digital radio technology however offers a far better quality of communications and offers furthermore interoperability between different agencies. In Belgium, the national authorities imposed a national tetra radio communications network for the emergency agencies, called the ASTRID (All round Semi-cellular Trunked Radio communication with Integrated Dispatching) network (Law, 1998). But the users are becoming increasingly demanding as of the coverage of this network. Consequently, improving the radio coverage has become the biggest issue.
Domestic smoke alarms and sprinklers
(Vysoká škola báňská - Technická univerzita Ostrava, 2012) Swann, Frank
Making further inroads into the reduction of fire deaths and injuries in the home is a clear ambition of the UK Chief Fire Offi cers Association (UK CFOA) and fi re-fighters alike. Despite signifi cant falls in the number of people whose lives are blighted by the effects of a domestic fire, the UK still feels it can do more to eradicate fired deaths and injuries. As this paper will show a consistent campaign to get smoke detectors installed in all properties, existing and new build, has had a dramatic effect. However the UK CFOA has now identifi ed that the next steps to achieve their ambition of 0 fire deaths is to ensure that properties have installed domestic sprinkler systems that will activate in the early stages of a fire. The campaign has started and the evidence is already starting to build that more lives can be saved!

Biogas : opportunities to improve safety and safety regulation
(Vysoká škola báňská - Technická univerzita Ostrava, 2012) Salvi, Olivier
The production of biogas is positioned as energy which can not only generate a source of renewable energy but also which recycles waste. In the context of sustainable development, the place of biogas is therefore essential. Several questions about safety issues, the harmonization of the regulations and the need to develop standards are discussed in this paper, based on the results of a workshop on biogas safety and regulation organized in November 2010 and the activities of the European Working Group on Biogas Safety and Regulation created after the workshop. The risks corresponding to the biogas production and use have been framed using iNTeg-Risk method and tools. Several defi cits for risk management have been identifi ed and a strategy to improve risk management proposed by the working group is presented at the end of the paper.
Process safety performance indicators
(Vysoká škola báňská - Technická univerzita Ostrava, 2012) Pasman, Hans J.
For over 50 years to measure safety performance the Lost Time Incident Rate, LTIR was used. Fortunately, over the years the learning attitude towards accidents changed from a retrospective to a pro-active one. In the 90-s the safety management system was introduced. No management though, without the Deming cycle of Plan, Do, Check, Act, and checking, means the need of indicators. Existing LTIR-values were used not realizing these refl ect personal rather than process safety. In 2005 after the BP Texas City refi nery vapor cloud explosion, awareness of the difference broke through and Process Safety Leading and Lagging Metrics were formulated. In January 2012 an international conference was held in Brussels organized by EPSC and CEFIC. Results will be summarized. The paper will explain briefl y, where we are now, and what still is ahead.

An approach to the quantitative assessment of risk due to NaTech events
(Vysoká škola báňská - Technická univerzita Ostrava, 2012) Cozzani, Valerio
External hazard factors as natural events and intentional acts of interference are perceived as important threats affecting the safety of chemical and process plants. The increasing frequency of some natural events having a particularly high severity also raised a growing concern for industrial asset integrity and for the consequences of major accident scenarios that may be triggered by natural events. The specifi c features of technological accidents triggered by natural events were recently recognized, and these scenarios are now indicated as NaTech (Natural-Technological) accidents. The analysis of past accident databases points out that NaTech accidents frequently impacted industrial facilities. Methodologies and tools for the specifi c assessment of the potential consequences of NaTech accidents were only recently developed, and are still missing for a number of specifi c NaTech scenarios. In the present contribution, a framework for the analysis of NaTech accidents is proposed and recent advances in the tools available for the assessment of NaTech events are revised.

(Vysoká škola báňská - Technická univerzita Ostrava, 2012) Orémusová, Emília; Makovická Osvaldová, Linda; Osvald, Anton
If we want to reduce the fl ammability of wood and wood materials we must be based on deep knowledge of the composition of these materials, their structure and their elementary building and other factors infl uencing many aspects of their fl ammability. The most important aspects of the fl ammability characteristics are important indicators as to the dynamics of fi re development, determination of fi re load and fi re risk and smoke production and its subsequent toxic gases. The paper deals with characteristics such as fl ammability and gross calorifi c value. Measurements were conducted on six selected species of deciduous trees, particularly in their leaves, twigs, bark and wood. Gross calorifi c value was determined in oven-dry sample.
The fire risk evaluation
(Vysoká škola báňská - Technická univerzita Ostrava, 2012) Nikolić, Božo
Following the defi nition of risk as a combination of a probability for its happening and the size of its damage, or, as a combination of the probability of a dangerous event, frequency of the exposure and the size of the damage, a signifi cant deviation away from the risk function in the areas of the occupational safety and health (OSH) and the fi re protection (FP) has been noticed. In the mathematical expression of the fi re risk according to the de Gustav Purt method (Purt, 1972), risk factors identifi cation was attempted. The basis for this fi re risk evaluation identifi cation method within the OSH area was developed by the authors from the HTS in Novi Sad (Nikolic and Gemovic, 2009a; Nikolic and Gemovic, 2009b). This way accomplished a simultaneous calculation of all fi re risks. The structures’ and their content’s risks have been processed, as well as risks towards people in the structures and fi remen extinguishing the fi re. Since the method has a communicative character, the calculated risk values are easily and accurately measurable by comparison.
