L'indicazione di pericolo H340 è uno dei codici H del Regolamento CLP (CE) n. 1272/2008: «Può provocare alterazioni genetiche <indicare la via di esposizione se è accertato che nessun'altra via di esposizione comporta il medesimo pericolo>.». Nel Regolamento CLP il codice H340 è l'indicazione di pericolo prevista per la classe Mutagenicità sulle cellule germinali, categorie 1A e 1B (Muta. 1A, Muta. 1B) (Allegato I; elenco nell'Allegato III, parte 1). In questa pagina trovi il testo ufficiale, a quale classe è collegata, il pittogramma tipico e un elenco di sostanze con classificazione armonizzata che la riportano.

Che cos'è l'indicazione H340

Testo ufficiale dell'indicazione H340 (Allegato III del CLP): «Può provocare alterazioni genetiche <indicare la via di esposizione se è accertato che nessun'altra via di esposizione comporta il medesimo pericolo>.»

Le indicazioni di pericolo (codici H) descrivono la natura e, se del caso, il grado del pericolo di una sostanza o miscela. Il testo ufficiale di ogni codice è stabilito dall'Allegato III del CLP, uguale per tutte le sostanze, e in etichetta va riportato per esteso. Il codice H340 si riconosce dalla classe di pericolo a cui è associato e dal pittogramma con cui compare.

Classe di pericolo associata a H340

Nel Regolamento CLP il codice H340 è l'indicazione di pericolo prevista per la classe Mutagenicità sulle cellule germinali, categorie 1A e 1B (Muta. 1A, Muta. 1B) (Allegato I; elenco nell'Allegato III, parte 1).

Codice H	Classe e categorie (CLP)	Codici	Tipo di pericolo
H340	Mutagenicità sulle cellule germinali, categorie 1A e 1B	Muta. 1A, Muta. 1B	salute

Approfondisci la classe collegata: Mutagenicità sulle cellule germinali (CLP).

Pittogramma tipico

Per la classificazione indicata sopra, l'Allegato I del CLP (tabella 3.5.3) prevede per H340 il pittogramma:

GHS08 – Pericolo per la salute (Allegato V, punto 2.4)

Eventuali altri pittogrammi presenti in etichetta derivano dalle altre classificazioni della sostanza o miscela.

Dove compare H340

Il codice H340 va riportato per esteso sull'etichetta CLP del prodotto, insieme a pittogramma, avvertenza e consigli di prudenza (P), e nella sezione 2 della scheda dati di sicurezza. Per le miscele, la presenza dell'indicazione dipende dalla concentrazione della sostanza e dagli eventuali limiti specifici.

Fonti

Codici delle indicazioni di pericolo secondo gli Allegati III e VI del Regolamento (CE) n. 1272/2008 (CLP). Gli abbinamenti classe–codice derivano dall'Allegato I (elementi dell'etichetta) e dall'Allegato III, parte 1; gli elenchi di sostanze derivano dalla Tabella 3 dell'Allegato VI; il testo ufficiale di H340 è quello dell'Allegato III. Verifica sempre la versione consolidata vigente e l'inventario C&L dell'ECHA.

Domande frequenti

A quale pericolo corrisponde il codice H340?

Nel Regolamento CLP il codice H340 è l'indicazione di pericolo prevista per la classe Mutagenicità sulle cellule germinali, categorie 1A e 1B (Muta. 1A, Muta. 1B) (Allegato I; elenco nell'Allegato III, parte 1). Il testo ufficiale per esteso è nell'Allegato III del CLP.

Dove trovo il testo completo di H340?

Nell'Allegato III del CLP: è uguale per tutte le sostanze e va riportato per esteso in etichetta accanto al pittogramma.

Quante sostanze hanno l'indicazione H340?

Nella Tabella 3 dell'Allegato VI il codice H340 compare in numerose voci: in questa pagina ne trovi un elenco collegato alle relative schede.

H340 compare sempre da solo?

No: una sostanza può avere più indicazioni di pericolo. In etichetta vanno riportate tutte quelle pertinenti, con i relativi pittogrammi e consigli di prudenza.
