From birth, a person faces various dangers associated with the technical field and the biological environment. In order not to put your own life at risk, everyone should have a certain set of knowledge that will help protect him from these threats and dangers. The issues of developing the right methods of protection against negative technical and natural impacts and the safe interaction of people with the environment are de alt with by representatives of such a scientific field as life safety. This article will help you understand what BJD is, as well as what goals and objectives this discipline pursues.
Definition and basic concepts
Before starting a global consideration of the question of what BJD is, it is first necessary to give it a clear definition. So, life safety is a science that considers the issues of human interaction with the technical sphere, as well as the interaction of people with the natural environment. And also the BZhD system includes the development of basic rules and recommendations for protecting a person from various negative factors. objectlife safety is a person, and the subject of study of the BJD is the development of a safe and comfortable existence of people.
The emergence of such a science as life safety is connected with the objective need of society for the ability to protect one's own life. The rules of safe behavior that this science derives are based on the practical experience of mankind, as well as on the theoretical basis of other related sciences.
The concept of BJD also includes the school discipline of the same name, which is taught to children in order to instill in them knowledge about possible dangers and threats. The basics of BJD help to gain theoretical and practical experience of behavior in difficult or emergency situations.
Tasks
After the definition of what BJD is, it is extremely important to understand what tasks this field of knowledge sets for itself. The main objectives of this discipline are:
- identification, classification and assessment of various negative environmental impacts;
- prevention of various negative impacts;
- liquidation of negative impacts;
- environmental control;
- creation for a person of a comfortable and safe state of the external environment;
- teaching people the right behavior in the face of threat or exposure to negative factors.
Thus, we can say that the tasks of life safety are a set of measures aimed at protecting a person from various negative factors.
Goals
The fundamental purpose of the BZD is to promote knowledge aimed at reducing fatalities and maintaining the he alth of people who are faced with dangerous external factors. Life safety is an extremely important science, because thanks to it it is possible to teach people how to act correctly in case of threats.
Science content
Life safety addresses the following issues:
- Prevention of negative impacts, which includes the identification and selection of a safe place to live, compliance with the norms and rules of labor protection, as well as instilling a he althy lifestyle in the population.
- Collective measures to organize a safe life, which includes the creation of safe working conditions, the protection of people from natural and man-made disasters, as well as the development of a regulatory framework in the field of protecting the he alth and life of the population as a whole.
- Creating a favorable state of the environment, which includes observing the rules for preserving the environment and reducing various negative impacts on it by mankind, as well as the rational and proper use of natural resources.
There are a number of axioms that have been defined by this science, namely:
- Any human activity or inaction carries a potential danger.
- Every activity should be as comfortable as possible and not cause harm to human he alth.
- All natural processes in nature orhuman activities are prone to loss of sustainability, and there is also a great risk of their negative impact, and everyone should be prepared for this.
- Safety and a clean environment can be achieved if their values do not exceed acceptable levels, given the complexity of their impact.
BJD factors
This science deals with the definition and classification of factors that are divided into dangerous and harmful. Harmful factors are those that lead to a deterioration in he alth and can reduce a person’s working capacity, however, after rest, a person returns to normal, and his body is able to continue functioning. Hazards are those that lead to injury, he alth problems or death of a person.
Both of these factors are natural and man-made. Dangerous and harmful factors are divided into biological, chemical, physical and psychophysical.
Biological agents are fungi, bacteria and viruses, as well as industrial emissions, biological weapons, plant treatments, etc.
Chemical factors are substances that a person inhales or consumes, as well as chemical weapons.
Physical factors are air humidity and temperature, solar radiation, wind speed, atmospheric pressure, as well as various vibrations and noises, current, ionizing radiation, weapons of mass destruction, etc.
Psychophysical factors are neuro-psychological effects on a person.
Conclusion
Summing up the consideration of the question of what BJD is, it should be noted that a person throughout his life is faced with many dangerous and harmful factors. The lack of theoretical and practical experience in protecting one's own life can lead to death, which in total creates a threat of increasing mortality.
Each person must independently take responsibility for their own safety in order to save people's own lives. And in order to understand how to behave properly in case of threats, an early and thorough study of such a discipline as life safety will help.
