SUMMARY. This wide-ranging article considers many aspects of burns and fire prevention. Physicians should be not concerned only with the treatment of burn injury - they must also have their say in discussions regarding the incidence of fire accidents and the alleviation of their magnitude. The modem world presents many dangers, while many risk situations continue to exist in developing countries. All these problems are considered, with particular reference to the Author's country, Egypt.

Introduction

In the medical profession practitioners invariably look on burns from a purely medical perspective as an accident, the results of which - the injury - being their main concern. Very few concern themselves with causation and fewer still with prevention or ways of reducing the damage, when in actual fact all aspects of fires and burns are interlinked and need to be tackled together. Surgeons, in particular, focus their attention on manifest bodily results, leaving aetiology to nonmedicals, engineers, industrialists, economists, the police, and rescue agencies.
It is intended in this discussion to emphasize the duty of physicians in general to have a say in reducing the incidence and in alleviating the magnitude and after-effects of fire damage in civil life. Mass casualties can result from fires whether during natural disasters or as a result of human behaviour. The patterns of these fires and their consequences differ markedly in the more developed world from those occurring in developing countries. Many factors combine to produce the patterns observed: the causative agents and the results of burns are related to the state of development and industrialization, and differ according to location in urban and rural communities. The patterns may be further complicated by the effects of cultural, behavioural and societal standards.
In the developing world, accidents and injuries - including burns and fires - are commonly accepted as part of the price that must be paid for achieving industrial development. Other factors - overpopulation, the crowding of people in marginal habitats such as shanty towns and rural districts, and congestion within the same dwelling - all add to the frequency of fire incidents and the severity of the resulting damage.
The introduction of modern technologies to unprepared and deprived citizens also takes a toll. Changes in life-style and the use - or rather misuse - of modem home equipment like electric appliances, gas heaters and cooking ranges all contribute to the increased incidence of fires and to the magnitude of the damage.
On the other hand, in the developed world, life in high-rise buildings and skyscrapers, overdependence on electric appliances, air conditioners, heaters and cookers, and the overloading of such equipment can all be causes of fire, despite stringent precautionary measures and safeguards. The crowding of amusement and recreational facilities and the occurrence of riots and violence in socially underprivileged or rebellious segments of society also add to the risk of fires. Not to be forgotten are factors of natural origin - earthquakes, forest fires, torrential rains, and lightning - all of which can cause catastrophic damage in terms of life and property.
In some countries like Egypt, where the process of development reflects a mixed pattern combining features from both the developed world and developing countries, the causes and consequences of fires are equally mixed. If considered alone, the tools available today for fire-fighting throughout the world are not sufficient to face the real size of the problem. Reliance on preventive measures, under all circumstances, continues to be the most effective approach to the containment of fire hazards. Industrial safety codes, building regulations, and fire relevant measures for prevention, extinction and escape are now highly developed and are reflected in contemporary architecture and life-styles. All these factors continue to receive the attention of specialists in several disciplines of science, technology, legislation and sociology.
Many of these studies generate results of high practical value that should be considered when a country defines or revises its fire safety codes and standards. In certain situations these may need to be country- or environmentspecific.

Egypt's experience in. the confrontation of fire hazards

Interest in Egypt was aroused recently, especially in the Academy of Scientific Research and Technology, by the launching of an international programme concerning the decade for mitigating the impact of natural disasters.
An important conference with international participation was held in 1993 that focused on ways and means of confronting fire hazards in Egypt. This interest was sparked by an alarming increase in the incidence of fires, which appear to be continuously on the rise. This unmistakable trend can be attributed to a number of factors, including:

  1. progressive and rapid population increase

  2. crowding in houses and workplaces, and even in recreational areas

  3. rapid expansion of production and commercial activities in industrial zones of new development areas which frequently lack adequate measures to counter fire hazards

  4. increased number of high-rise buildings and housing towers lacking effective and fire-related systems

  5. lack of sufficient measures to protect old buildings, mainly made of wood, without provision of sufficient safeguards against dangers arising from the use of electrical systems and equipment. During the present generation alone, incalculable losses have resulted from fires that destroyed the Cairo Opera and Gawhara Palace

  6. rapid change in life-styles, particularly in rural areas, where houses are still built of clay, while the use of modem electric appliances becomes more widespread

  7. distribution of electric power by means of the rural electrification network, with its high-tension cables hanging over residential areas. The hazards are aggravated as a result of the farmers' habit of storing quantities of rice straw and cotton stalks on the roofs of their homes. Every year, in spring, there is a season in Egypt (Khamasin) when strong sandstorms blow through the entire Nile Valley, frequently followed by heavy rains. These effects sometimes combine to kindle fires that can cover vast areas and destroy entire villages. During this season, as a result of the frequent fire incidents, there are many casualties with severe burns

  8. the spread of marginal habitats and shanty towns, with a deterioration in living conditions in urban slums, in most cases caused by the migration of unemployed town-dwellers and farmers. These areas are characterized by congested population where the absence of sanitary facilities and other public services combines with dangers deriving from misuse of electricity and other sources of energy

  9. the introduction of live city gas into houses, which may also lead to risks associated with leakages and/or misuse. The situation is worse in areas which use bottled gas, where the containers may be substandard, faultily manufactured, or improperly handled. The same applies to oxygen and acetylene cylinders used in street welding and to autobody workshops

  10. the chronic problem of proper town planning, which has left us with narrow streets packed with buildings, together with inadequate or totally absent fire hydrants in vulnerable areas. The siting of petrol stations in the heart of crowded residential areas is another source of danger

The magnititude of the problem

During the 1990s, fire-related losses in property were estimated to be in the order of $100 million, while the value of lost antiquities and places of historical interest is beyond estimation. The number of fire incidents is constantly rising, reaching the level of 31,254 cases in 1994, with more than 4000 outbreaks of fire occurring in the city of Cairo alone. It is estimated that the cost of fire losses in this single year will exceed $400 million.

Types of fire seen in Egypt

  1. Moderate and multiple smallfires
    Fires can be easily prevented and confronted if the appropriate safety codes are observed and enforced. Another critical need is the extension of the network of fire hydrants to vulnerable and crowded urban districts. There is also a dire need to review the situation in large production facilities, as well as in small workshops, to ensure the observance of industrial safety codes for the prevention of fire and the protection of life and property.

  1. Serious fires
    The occurrence of serious fires threatens to assume disastrous dimensions if the outbreaks happen in high-rise buildings, where the situation may be aggravated by leakage from gas pipelines. These are likely to cause massive life losses and extensive injuries in addition to heavy losses in property. In the USA there is now in force a special fire safety code for high-rise buildings. Its requirements are oriented towards the protection of these vulnerable structures, and concentrate specifically on ways and means of early detection, as well as in situ fire-fighting. There is also emphasis on the heightening of public awareness and on the dissemination of information among the general population and in schools. Fire drills are common in many institutions and constitute part of public education efforts of this nature, which are the responsibility of the local civil defence authorities and other health institutions.

  1. Unpredictable disasters
    Although forests are very few in Egypt and forest fires scarcely a problem, a review of the literature reveals that in this country the outbreak of unpredictable forest fires is a common and widespread phenomenon that can have disastrous consequences. We are inclined to classify rural fires as nature-related but not as natural disasters, because in the worst cases they do not result from human negligence and are not purely the direct products of natural phenomena.
    These fires are unpredictable with respect,to both place and time. Their consequences are complicated by the fact that they occur in locations that lack transport and communication facilities, where road conditions and the availability of water for extinguishing purposes do not lend themselves to quick and effective rescue work. The toll in terms of life and property can be excessive.

  1. Fires due to natural disasters
    In Egypt, it is estimated that losses due to natural disasters account to no more than 35% of all losses, while about 65% are related to human factors. Fires due to earthquakes, lightning, torrential rains, and floods are relatively rare in comparison with other geographical areas such as North America, where more than 25,000 fires of natural origin occur every year. For this reason the US has developed a special code (NO.78, Standard 5,1) through the National Fire Prevention Agency.
    We in Egypt are however far from immune from the disastrous results of fires caused by natural phenomena. One instance was an unusually heavy downpour that resulted in floods in parts of Upper Egypt, when fires broke out in oil storage tanks standing in the way of the sweeping waters. Casualties from these fires far exceeded those resulting directly from the floods and the destruction of houses.

General preventive measures

It may generally be true to say that until the beginning of the 20th century the chief concern of researchers and practitioners in the field was simply to prevent the spreading of fires. The focus of interest then shifted towards studying ways and means of prevention, early warning, and early control of fire outbreaks. The findings, now time-tested and field-proven, are the results of many years of experimental research in specialized institutes in many developed countries. The National Bureau of Standards (now the National Institute of Standards and Technology) of the Department of Commerce in the USA has a team of specialists who dedicate all their time and efforts to developing means for the prevention and combat of fires, including fire safety standards and codes that range from recommended guidelines to rules that are legally binding.
The norms that are now commonly observed for fire prevention and control are generally of the following nature:

  1. Preventive measures
    In ideal situations, preventive measures should be adopted and implemented in the conceptual stages of the planning of new development areas for residence and production. Designers are required to make effective and adequate provisions for fire prevention and, in the event of outbreaks, fire-fighting. This refers to the location, distribution and construction of storage buildings, their outlets and inlets, access to their contents, and facilities for the safe disposal of industrial waste, especially if health- or fire-hazardous. Basic to all facilities is a network of extinguishing water lines and suitably distributed fire hydrants. In the detailed design of industrial and residential buildings, strict adherence to safety codes should be among the prime concerns of the architect and the builders.

  1. Early warning systems
    These have become highly specialized in function and sophisticated in performance and are direct products of advanced developments in the discipline of sensing, signalling, and instrumentation technologies. Their sensitivity standards have reached heights that make them now truly dependable for advance alerting in cases of fire outbreak. They include sound and visual alarms, smoke, heat and light detectors, and the remote alerting of fire-fighting authorities, all in nearly failure-proof systems.

  1. Fire containment measures
    These are countless in number and highly varied in their nature. After the outbreak of a fire, their primary purpose is to prevent it from spreading and aggravating the consequences. Legally instituted codes are (or should be) available to this end, and several prescriptions for physical arrangements are (or should be) observed.
    These include:

    • provision of suitably located and distributed fire exits which should be free of obstacles at all times. At regular intervals, users of the premises should practise fire drills that include the rapid and orderly use of these exits

    • provision of sufficient numbers of fire hydrants at suitable locations within and around the premises

    • equipment of premises with automatic sprinklers for spraying water or other extinguishing media into the environment, as deemed most appropriate

    • creation of first-aid stations that are accessible to local residents and rescue personnel

    • provision of automatically operated fire extinguishing gases (and foam ) or special media that are specific for fighting chemical fire in premises where dangerous chemicals are stored and handled. Strict observance of rules of practice in these situations should be a cultivated habit of all personnel

    • availability of hand-held and portable fire extinguishers at all times. Personnel should be trained in their use until all fire-fighters can handle serious fire situations

  1. Development of safety codes
    A wide range of such codes has been developed over time, in many different countries. These codes relate to a number of aspects pertaining to the design and construction of public buildings and of production and storage facilities. Many codes also exist for edu2ational and R&D (research and development) buildings, as well as for hospitals and government offices. There are also highly elaborate codes governing the construction and operation of institutions where chemicals and electric equipment are in routine use. These codes invariably include elements that address the question of the hazards of confinement, by the creation of physical barriers to prevent the spread of fire from one space to another. They also include the provision of fire-proof partitions or explosion-proof equipment and electric installations - all for the prevention and/or containment of the effects of fire damage. Of all the measures, those aimed at the protection of human life feature highest in all codes.
    Needless to say, any code of design or practice is of little value unless its enforcement is founded on the training of sufficient numbers of qualified personnel possessing the knowledge and courage to face dangerous situations, and fires are among the most fearsome of dangerous situations.

 

RESUME. Cet article, de grande envergure, considère beaucoup des aspects des brûlures et de la prévention des incendies. Les médecins doivent s'occuper non seulement du traitement des lésions dues aux brûlures - ils doivent aussi exprimer leur opinion sur sont ce qui concerne l'incidence des accidents du feu et l'alléviation de leur ampleur. Le monde moderne présente beaucoup de dangers, tandis que diverses situations à risque continuent à exister dans les pays en voie de développement. Tous ces problèmes sont considérés, avec un particulier intérêt pour le pays de l'Auteur, l'Egypte.
