1. PREVENTIVE MEASURES RELATED TO THE SEMICIRCULAR

LIPOATROPHY IN EXISTING BUILDINGS. PROTOCOL OF

ACTION.

This protocol has been designed to evaluate rooms and working places in existing

buildings, taking a look at the rehabilitation of them. The aim of this evaluation is

to study the indoor rooms, valuing the current characteristics and seeing the

potential dangerous agents, which can influence to the appearance of the

semicircular lipoatrophy.

Basically we try to study the air conditioning, ventilation, humidity and the indoor

building rooms, also analyzing the existing office equipment and office furniture.

This study should be accompanied of thermohigrometric, electrostatic and

electromagnetic initial valuation, to check if the indoor rooms conditions are

adequated or not. These results obtained, need to be interpreted as an indication

of the building conditions, and allows us to anticipate the needs of intervention if

needed, directed to the appropriate rehabilitation of it.

The assessment results are necessary to be related with environmental aspects

that we have mentioned at section A in the original project, and the acceptance

or not of the values, will be realized as a check-list .

APPEARANCE OF THE SEMICIRCULAR LIPOATROPHY.

This datasheet has been designed for taking some thermohigrometic,

electrostatic and electromagnetic measures to verify the suitable indoor

conditions of building, once the work is ended. The results obtained must be

treated as a faithful reflection of the reality, that is taking place and the

environmental values that could affect directly people who develops his

professional activity.

It is necessary to study the results and be related following the environmental

criteria checking the compliment or incompliment throw the obtained values. Its

possible that it would be necessary to modify the thermohigrometic, electrostatic

and electromagnetic conditions.

5. POSSIBLE SOLUTIONS OF ACTION.

Environmental criteria

Centralized control of the air conditioning system

It would be very advisable the fact of centralizing the system of air conditioning,

controlling thus the global conditions of the building.

Installation of humidifiers.

In case the relative humidity is lower than the recommended, its possible to

install humidifiers to raise it.

Installation of sensors to automate the air conditioning system.

To be able to control the relative humidity in an automated and exhaustive way,

its recommended to install hygroscopic sensors to obtain an historical report,

also keeping constant the humidity. The machine will be turned on automatically

when one of the sensors detects a lower value than the estimated.

Installation of enthalpy exchangers joined to the renovation of the air.

Instead of the crossed conventional interchangers, the installation of enthalpys

interchangers in the room, allow the air renovation. It also could recover the air

humid load returned and also keep a higher relative humidity in a natural way.

Design of the furniture

Desks

Rounded edges with a large surface of contact or protect with a rounded piece of

plastic,to isolate the metallic structure in contact with the employee.

Metallic structure ground connected

To obtain a better dissipation of the static loads, it is necessary to connect the

desk to the electrical ground line connection of the building.

Isolation of the electrical installation in contact to the metallic structure

Improving the electrical isolation of the wired, related to the desk, its influence

will be reduced.


18

Chairs

Metallic structure electrically connected to wheels which conduct electricity

The chair with a conductor line installed both at the armrests and at the metallic

structure, its is discharged throw a conductive leg, removing the electrostatic

load.

Seats made of not triboelectric material and good electricity conductor

Seats must be made with a dissipative and not triboelectric material, that is to

say that avoids generating electrical loads in the human body. For that reason it

should be used pieces of cotton commercialized as antistatic, avoiding articles

with synthetic fibers, silk, rayon, wool, etc.

Footrest

Another measure to improve the conductivity of the materials from the

workplace, it is possible to install footrests that lead the electricity to the ground,

hereby lets dissipate the electrostatic loads. The conductive floor combined with

a conductive footwear, in order that the human body remains ground connected

surely. The top limit resistance of the conductive footwear about static electricity

must be 1,5105 W.

Design of finishing surface materials

Metallic floor

Ground connection

To assure the dissipation of the electrostatic loads from the furniture and office

workers, its necessary to connect the metallic elements in the ground connection

line of the building.

Not metallic floor

Good conductors and not triboelectrics

To allow the dissipation of the electrostatic loads from the furniture and office

workers, insulating surfaces cannot be placed. Also it is necessary to bear in

mind, not to use triboelectrics materials.


19

Increase of the conductivity with superficial treatments

The superficial treatment is realized generally with the application of prepared

antistatic mixtures, added to the detergents, paintings, lubricants, impregnants

and other substances, to increase the superficial conductivity to favor the

formation of a hygroscopic conductive film. Its possible to use commercial

antistatic products, in dissolution with water for an application in synthetic

insulating floor, for a soft washing-up with mop or antistatic humid cloth with the

dissolution. The film hereby created is soluble in water usually wear down with

the use, so it is necessary to realize the treatment almost daily, though it is

acceptable if it is done weekly.

Cleanliness with antistatic products

To reduce the aptitude to generate electrostatic loads as well as to increase his

conductivity, its necessary to clean with antistatic products the floor with few

conductivity, specially at the toilets and in the bar.

Apertures to the South, South-East or South-West

Curtains or vinyls

In the zones of the building orientated to the south-east, south and west there is

normally a high sunstroke that increases the temperature of these areas and

therefore it reduces the relative dampness. To solve this problem its necessary

to install curtains and vinyls to reduce the sunstroke and stabilize the relative

humidity.
