Toxic smoke in the burning of selected substances, detection and protection intervening fire
 ŠEBA, Jaroslav
Toxic products of combustion released by selected substances {--} their detection and the protection of firefighters I have opted to focus my Bachelor paper on this subject on the strength of my 20 years of working at the law-enforcing department of Fire Rescue Service; consequently, I am well aware of the difficulties that the firefigthers meet in their attempts at obtaining vital information. I have decided to investigate the subject and offer the results so that the fireman units could be properly trained. The paper is divided into several sections. The first aims to find out to what extent the units of the South Bohemian Fire Rescue Service are equipped with detection devices; the second examines the options of protection available to the firefighters in action; and the third section pays attention to the current standards of training given to the firefighting units deployed in the regional Service. The fourth section contains a comprehensive chapter on the noxious products of combustion, presenting available information on substances most often released in their burning. The next section provides a questionnaire survey designed to map the knowledgeability of firefighters and, to permit comparisons, also the awareness that the general public has of the substances and the toxicity of their combustion products. The chapter included to present evaluations and analyses starts with a description of materials to be ignited. The products of their burning were gathered using the Tenax tubes to be later analyzed in the laboratory. The lab analysis results are presented together with the major effects that the substances may have on human body. With the questionnaire survey evaluated, it became obvious that the firefighters were considerably better informed than the general public in all areas thus surveyed. Still, the incorrect answers returned by the freighters testify to a great deal of deficiencies that the system of training should address and regular training sessions of units should remedy. Excellent results were obtained for firefighters in action, since in most cases their level of protection was found higher than what was actually necessary. The level of knowledge encountered in the general public respondents proved to be below the average. Their awareness of hazards that the combustion products may pose for humans should be heightened (e.g. through a campaign able to provide information on the subject) since the products may be detrimental to the health of just anybody.
