Industrial Safety II: Risks of
Unsafety
Fires
Fire Classification
For extinguishing purposes, not all fires are the same,
they will depend on the type of fuel that burns, so that they behave in one way or another.
Basic Principles of Extinction
As previously mentioned, the fire
would go off if by any procedure any of the elements that produce, namely: Oxygen, Heat, Fuel and Chain Reaction.
Fire Chemistry
Everyone knows that for there to be combustion, it is necessary that
three elements are present: oxygen (oxidizer), heat and fuel
Nature of Fire
Fire is the effect produced in a fuel when it is
it applies the necessary heat, to pass from its natural state, to another of lower density and in the presence of oxygen.
Stages of a Fire
To better understand the need for
of automatic installations in the fight against fire, it is worth remembering how to
develops this, with intervals of time
Combustible Dust Explosion
Risk Control
The analysis of the phenomena that take place in
fires and/or explosions in combustible dust allows establishing a logical chain
applicable to risk
General Principles of Prevention
Being necessary the coexistence in space and time with
sufficient intensity, of all the factors already mentioned, the preventive elimination of one or more of them, will prevent the
onset of either phenomenon.
Qualitative Risk Assessment
The conditions determined for a powder
fuel whether or not it is explosive have not been investigated in depth, however it is evident that the condition
whether or not a combustible dust is explosive, and its explosive characteristics, if so, are related
with the reaction conditions
General Principles of Fight
it is necessary to adopt as a priority
preventive measures that limit the probability of a fire or burst
Places and Work Spaces - Work in Spaces
confined
Order and Cleaning
Order is necessary to achieve a
more efficient use of available space, and is always an important complement
of the means of protection.
Confined spaces
They have been defined as those spaces sufficiently
closed so that any hazardous air pollution present therein cannot be avoided or removed
through natural ventilation through the openings that exist.
Places and Work Spaces
The design and construction characteristics of the
Workplaces will be such that they offer adequate security against the The design and construction characteristics of the
Workplaces will be such that they offer adequate security against the risks
Risks in Confined Spaces
Given the particular characteristics of these
recitos, at this point the risks that exist in the spaces will be identified.confined as well as their description,
Construction Safety
Works near power lines
The minimum safety distance for those jobs that are
carried out in the vicinity of high voltage installations, in medium voltage (measurements between the closest point in voltage and any
extreme part of the operator or of the tools and materials that he
excavations
In the excavations and in the works that
they are carried out, the main danger originates from the accidental movements of the ground
Work team
Within the term work teams, we have identified
some groups that, either because of the singularity that their members include, or because of the generality that they represent,
They constitute elements worthy of particular study.
excavations
The great variety of the parts of the body of the person to
protect makes the equipment to use many, and many features to take into account.
