INDUSTRIAL SAFETY II, RISK OFUNSAFETY - Coggle Diagram

- - - - The expansion, (thermal effect of the calorific power), of a large quantity of gases, (volume of gases generated), at a high speed (reaction speed) are the specific effects that characterize any explosive reaction.
        
        "For an explosion to occur, the dust must be in air suspension."
        Dust can be in bed and in cloud. Bed dust is understood as the layers of dust deposited on horizontal surfaces of machines, pipes, windows, floors, etc., of greater or lesser thickness (0.1 to several cm.). By cloud dust is understood an air-dust mixture, which normally affects large volumes of air and with concentrations that can vary from g / m3 to k / m3.
        
        Explosion Hazard Fire Hazard
        This shows that in an enclosure with dust production, the fact that it is present in a bed or in a cloud or both is not decisive because, depending on the external conditions, it can change from one form to another.
- - - - In order to facilitate the task of choosing the appropriate extinguishing agent, with respect to the fire to be extinguished, it is important to classify them, grouping them with respect to the fuel that gives rise to it.
  - - - As would happen with the Fire Triangle, in the Fire Tetrahedron, by suppressing one or more of its components, it leaves it incomplete and therefore fire is not produced.
  - - - Cooling.
        It consists of eliminating heat to reduce the temperature of the fuel.
      - Suffocation.
        It prevents the combustible vapors that are given off at a certain temperature for each matter, from coming into contact with the oxygen in the air.
      - Dilution.
        Also called " Desalimentation " and which consists of removing or eliminating the fuel.
  - - - Fire, therefore, is caused by the incidence of a heat source that comes into contact with the fuel and initiates the emanation of gases, which ignite when the temperature of their flash points is reached.
  - - - Fire protection.
        Today, protection against fire and its devastating consequences, fire is part of our culture, focused on improving and increasing safety levels in all areas.
- - - - First aid supplies and premises
        Workplaces will have materials for first aid in the event of an accident, which must be adequate in terms of their quantity and characteristics, the number of workers, the risks to which they are exposed and the access facilities to the assistance center.
  - - - Structural safety
        The buildings and premises of the workplaces must have the structure and strength appropriate to their type of use. Thus, for their intended use, all structural or service elements, including work platforms, ladders and ladders,
        
        Work Spaces and Dangerous Zones
        The dimensions of the work premises must allow workers to carry out their work without risk to their safety and health, and in acceptable ergonomic conditions.
        
        Floors and Openings
        One of the primary causes of accidents due to the floor is slipping, so it is very necessary to assess the danger of slipping on the surface of the different classes of floors.
        
        Partitions Windows and Openings
        Transparent or translucent partitions and, especially, glazed partitions, located in the premises or in the vicinity of work stations and traffic routes, must be clearly marked and made of safe materials, or be separated from said posts and tracks, to prevent workers from hitting or injuring themselves in case of breakage.
