It is estimated that 5,300,000 EU workers are potentially exposed, more than 70% of them in the construction sector. Beside construction, the following industries are estimated to have the highest exposure levels compared to the other industry sectors as well as the highest numbers of exposed workers: manufacture of other non-metallic mineral products, other mining and quarrying, manufacture of basic metals, manufacture of fabricated metal products, electricity, gas, steam and hot water supply.

Brussels, 13.5.2016 SWD(2016) : 152 final COMMISSION STAFF WORKING DOCUMENT IMPACT ASSESSMENT Accompanying the document Proposal

for a Directive of the European Parliament and of the Council amending Directive 2004/37/EC on the protection of workers from the risks related to

exposure to carcinogens or mutagens at work

Considerazioni

• I prodotti contenenti silice cristallina in quantità superiore allo 0.1% non debbono necessariamente essere classificati H350i

• Generica definizione di attività comportanti esposizione a silice cristallina generata dai processi di lavoro

Revision of the Carcinogens Directive

The inclusion of RCS in the Carcinogens Directive or in the ChemicalAgents Directive should address process generated RCS, and moreprecisely in our opinion: work processes involving occupationalexposure to respirable crystalline silica in the form of freshlyfractured particles generated through dry processes such as drycutting, grinding, drilling, crushing, sand and abrasive blastingoperations in a concentration above 0.1 mg/m³

“processi di lavoro comportanti un’esposizione professionale a silicecristallina respirabile in foma di particolato con segni di fratturafresca derivante da processi a secco quali operazioni di taglio,macinazione, perforazione, frantumazione e sabbiatura inconcentrazioni inferiori a 0.1mg/m3”

Unveiling the Variability of "Quartz Hazard" in Light of Recent Toxicological Findings.

Pavan C1,2, Fubini B1,2.

Recent investigations have shown that crystallinity is not implied in the pathogenic process of silica per se, while patches of disorganized silanols at the surface of both crystalline and amorphous particles can promote membrane damage and inflammation, a process at the origin of silica-related diseases.

We ascribe the origin of the variability of silica hazard mainly to the distribution of various moieties at the particle surface, with silanols playing the major role. Toxicity turns out to be likely predictable by an ad hoc surface characterization.

Ci saranno ripercussioni sulla supply chain del settore dei minerali industriali?

È di vitale importanza che i clienti delle aziende produttrici di minerali per l’industria comprendano che questa nuova direttiva europea riguarda esclusivamente il controllo dell’esposizione dei lavoratori alla RCS generata da procedimenti di

lavorazione e non ha alcun legame con la classificazione e l’etichettatura dei prodotti contenenti silice cristallina.

I prodotti forniti non dovranno essere sostituiti o etichettati come cancerogeni, ma l’esposizione dei lavoratori alle polveri aerodisperse

eventualmente generate dalla lavorazione di prodotti minerali e di materie prime contenenti silice cristallina dovrà essere valutata e controllata in modo idoneo,

applicando la nuova legislazione e le buone pratiche NEPSI. Molti settori a valle che impiegano prodotti minerali in Europa adottano già buone pratiche di

lavorazione industriale, in linea con le buone pratiche NEPSI.

Significato dell’OEL

• Il valore di 0.1 mg/m3 è un valore vincolante (BOEL)

• Gli stati membri della Comunità Europea nel recepimento della Direttiva possono

adottare unicamente valori uguali o inferiori a quello proposto

Now the new challenge is to identify an “action level” (AL) below 0.1 mg/m3 able to prevent the risk of lung cancer. The respect of the AL (if it will be identify it) could permit to avoid to apply the actions required

from the CMD directive (closed system, ……)
