Flammable objects always attract the attention of firemen. This is understandable: possible explosion will not only cause damage to the objects of economic activity, but also can claim the lives of many people. Crash on flammable objects belong to the complex, and for their localization and elimination the specific technologies and special means.

causes explosions

Fires, explosions. Definition

The Fire is called ignition, covering a certain area. As a result of this fire, observed property damage, damage to the environment, there is the threat of loss of life or health for humans. The fire extended in time: it can last for hours and even days. Often a fire occurs as a consequence of the explosion – when a sudden ignition of the gas sharp increase in temperature leads to the ignition of flammable substances around. There are other cases when slow heating leads to the detonation of explosives.

causes of fires and explosions

The Explosion – sudden ignition of combustible or flammable compositions of mixtures of solids. Ignition occurs in a very short period of time. With the explosion of a combustible substance is ignited dramatically, creating a contrast between the ambient temperature and the hot hell in the epicenter of the explosion. From this drop destroyed even fire-resistant materials, which, in principle, can withstand prolonged heat. The main reason for the explosions — detonating combustible substances.

Explosive devices

In most cases, to explosive construction are building industrial, commercial purpose. This can include warehouses and production premises of shops for the manufacture and storage of explosive substances, mixtures or their components. Most cases of fires, explosions or leaks of hazardous mixtures is recorded in industrial facilities, specializing in the production of combustible materials and explosives.

the conditions and causes of fires and explosions

The Second risk group – mine. Methane and coal dust – the first cause of fires and explosions in the mining industry. These substances are present in each coal production and pose a considerable danger to the lives of the miners. Of course, in every mining site there is the personal fire brigades and taken all the necessary security measures. But it doesn't guarantee full prevention of explosions and fires.

The Third group of risk are military training grounds, where, over time, accumulate unexploded shells and mines in large numbers. Their safety is the direct responsibility of combat engineer units, but when the situation gets out of control, it is taken and the civil service Ministry. The effects of PE on the polygons carefully studied, but the results of the investigations in most cases are hidden from the General public for reasons of secrecy.

Main reasons

The Fire situation does not occur in a vacuum. Experts identify the main causes of fires and explosions in manufacturing, including:

  1. Violation of the staff regulations and rules of fire safety.
  2. Neglect the fire from the staff.
  3. The Malfunction or misuse of electrical equipment.
  4. Conduct certain operations without proper equipment and without compliance with safety regulations.
  5. The Effects of explosions, triggered by an emergency situation or leaks of flammable substances.
  6. Disregard for order non-observance of rules of cleanliness in the working area.
  7. Storage of inflammable materials and substances in prohibited places.
  8. Arson.

Both Intentional and unintentional causes of fires. Whose responsibility

The Conditions and causes of fires and explosions-a separate issue that is carefully studied by the staff of the Ministry and the various agencies responsible for human safety and the environment. The result of this work was to identify the basic factors causing fires and explosions.

Causes of fires

Cases of negligent attitude to safety – this is the most common cause of fire. It is, in fact, should be regarded as intentional, as the risk of fire or explosion in this case are the work of human hands. This technical malfunction, and failure of technology production processes, and more. The damage from such injuries are usually covered by internal resources of the enterprise or for the account of the person whose actions led to the fire.

A Smaller proportion of all emergency incidents in this area are the fire, caused by a coincidence – the lightning strike, earthquake or hurricane. Natural causes of fires and explosions are a standard contract item of industrial insurance. The damage from the force majeure can be covered by insurance reimbursements.

Prevention of fires and explosions

The Conditions and causes of fires and explosions – the prerogative of the Department of safety, emergency and inspectorsthe protection of labor. They jointly developed a valuable volumes of instructions and recommendations, compliance with which will significantly reduce the risk of fire or explosion. The entire set of rules aimed at the prevention of fires, based on the analysis of the causes of fires and explosions, as well as their localization and the establishment of algorithms for successful extinguishing.

Prevention of fires at the enterprises can be divided into four groups. These groups work closely inspector for fire safety and emergency workers. Let's take a closer look at measures aimed at preventing the causes of fires and explosions in factories and commercial properties.

main causes of the explosions

Technology and control

In the first paragraph lists the conditions under which excluded the possibility of fires and explosions. Here are the recommendations, compliance with which leads to prevent the formation of explosive mixtures and formulations, provoking the emergence of pockets of flame. The developers of the recommendations propose, if possible, to analyze the causes of fires and explosions, their consequences, to replace dangerous substances less inflammable and explosive or to add to the compositions an inert additive. The introduction of combustible additives N2, CO2, the dilution of the gases with carbon monoxide significantly reduces the chance of ignition and makes such substances are less hazardous when transporting, moving or storing.

Modernization and fire

A Separate item in this group there are recommendations concerning improvement of technological processes. Refers to technologies that significantly reduce the amount of hazardous substances in the equipment used. This may also include automated processes that reduce human involvement in the management of dangerous machinery; sealing systems, industrial plants and industrial tanks.

Protective equipment

The Use of safety devices significantly reduces the likelihood of fires and explosions. This item includes installation of lightning arresters, compensators, earthing. This may also include the installation of modern ventilation systems, which direct the flow of air in the designated areas, regular monitoring of the efficiency of heating systems and power grids.

causes explosions and fires their consequences

The Last paragraph of this group can be considered explanatory work with the personnel of the enterprise, where are explained the causes and consequences of explosions and fires on specific examples and best practices for fire safety and rules of conduct in the workplace.

Preventive measures

The preventive actions directed at the stage of planning the construction of an industrial facility to reduce to zero the probability of fires and explosions.

Among these measures are the following:

  • To prevent the possibility of large-scale distribution of damage caused by explosion or fire;
  • Rational definition of locations for development taking into account landscape features, predominant winds, climate, roads, etc.; and
  • The layout of buildings, temporary structures and permanent structures complying with the safe distances between construction sites;
  • Zoning of the building, the location of roads, entrances compliance with fire protection requirements;
  • Exact observance of the recommendations of the Builder in terms of choice of non-flammable materials;
  • Location and support in operating condition existing fire barriers: layers, firewalls, fire rated ceilings, and more.

Safe evacuation

Preventive safety measures include planning routes that can be used during the evacuation of material values and the people from the disaster zone. When you run this item, you should pay attention to the following points:

  • Objects should be placed on the floors, taking into account their potential fire or explosion hazards;
  • Should arrange a sufficient number of emergency exits, staircases, doorways, other;
  • Engineers have an obligation to include in the main project the possibility of creating a fault alarm systems, traps, tanks, etc.

Conditions for successful fire suppression or hearth blast

The Causes of explosions and fires can be successfully controlled in compliance with safety regulations. An equally important factor in the destruction of the source of fire danger is the exact algorithm of actions aimed at eliminating the source of explosion or fire. Such actions include:

  • Proper selection and arrangement of means of extinguishing fires. The list of devices for fire fighting must be agreed with the local inspector of fire protection.
  • Construction unobstructed access to fire extinguishers and hydrants, reservoirs and water systems.
  • Provision of building and object special signaling devices, signaling a sharp rise in temperature or smoke in the premises.
  • Development of instructions, allowing the plant personnel to respond correctly in case of fire.

How is the development of instructions?

Basically, the design procedure is based on theanalysis of the causes of fires and explosions that occurred earlier at the enterprises of the same industrial focus. This analysis:

  • Takes into account the nomenclature and use in production processes explosive and flammable compounds.
  • Determines the level of fire risk in the premises;
  • Identify the factors of production, upon the occurrence of which the possible leakage of flammable substances.

So gain experience of the prevention of fires and explosions in organizations and defines the procedure, following which you can preserve the life and health of employees and company property. The development of the guidance professionals involved in fire safety, and control over their implementation rests on the shoulders of the administration. Typically, in enterprises where the number of employees exceeds 70-100 people are assigned special responsibility for fire safety. In companies where the number of regular employees is not more than 70, this position is the Director or Manager.causes explosions

Causes of fires at home

Specific area of research are analysis of the causes of explosions and fires in the home. In most cases, house fires happen as a result of:

  • Improper use of electrical appliances;
  • Work with faulty electrical equipment;
  • Violations of the rules of use of gas stoves or columns;
  • Careless handling of open fire.

To reduce the number of household fires with the population are led preventive discussions, and students are taught mathematics. Not always the efforts of teachers or inspectors lead to the understanding of the dangers of open flame, but work in this direction is constant. I hope that soon the causes of fires and explosions is to know each child and young person, and the number of lives being lost by fire, will be reduced to zero.
