GENERAL
Asbestos was used for its…
Thermal properties : Excellent thermal insulator (and non-flammable),
Acoustic properties : Excellent soundproofing material,
Chemical properties : Resistant to acid when mixed with cement,
Mechanical properties : Higher tensile strength than steel,
Resistant to abrasion.

7. Deterioration of the material: natural or human causes
RISKS
Deterioration of the material: natural or human causes
Dispersion of asbestos fibres in the air
They say we’re taking a risk with asbestos!!
Not if we don’t breathe!
Threshold
People  Inhalation of the fibres… serious illnesses
Premises  Contamination… no entry

EFFECTS ON HEALTH
Recognised route of entry into the body: INHALATION
Active/passive exposure
Limits for workers and for the general public
Occurrence of illness: 15 to 40 years after exposure
Serious illnesses: asbestosis, lung cancer, mesothelioma, etc.

PREVENTION AT CERN
2. Risk management
- ban on use of asbestos,
- locating and identifying, monitoring the condition of materials, carrying out tests.
3. Work management
- evaluation before starting the work,
- follow-up,
- work performed by personnel with the necessary knowledge and skills.
6. Information and Training
- supervisors, contractors, TSOs, firefighters, etc.

WORK MANAGEMENT
2 APPROACHES
Containment or removal (asbestos removal)
For example: removing the heat insulation from a network of pipes, removing
sprayed asbestos from a structure, removing floor coverings, removing tile adhesive, etc.
Work on equipment that could release asbestos fibres (working with asbestos)
For example: repairing a leak in a heat-insulated pipe, relaying of a floor covering, changing an asbestos-cement sheet, altering a false-ceiling panel, drilling or cutting in a wall containing asbestos, work on asbestos-cement cable carriers, dismantling of a ventilation system (braided gaskets), etc.

ASBESTOS REMOVAL
Obligatory if materials are in a poor condition,
during demolition, or in the phase before work
Need to bring in specialised contractors approved
in France and Switzerland,
The contractor must draw up a plan for the removal and submit it to the relevant authorities (at least one month in advance!),
Requirements for the worksite: a contained area with an airlock system, a guaranteed water supply and uninterrupted electricity supply, special waste management procedures by the contractor, air contamination checks, etc.
A “green light” inspection (by the HSE Unit or the authorities) before removal begins

WORKING WITH ASBESTOS
CERN must:
inform the contractor of the presence of asbestos,
require the contractor to take this risk into consideration,
incorporate the contractor’s proposals in the risk prevention plan,
check that operational and precautionary procedures are implemented.
The contractor must demonstrate his ability to:
evaluate the risks associated with the presence of asbestos in the framework of the work concerned
draw up operational procedures, incorporating safety measures,
inform and train all his personnel.
Do not improvise!!
