Gas infiammabile (CLP): categorie, pittogramma e sostanze classificate

La classe di pericolo Gas infiammabile (codice Flam. Gas, pericolo di tipo fisico) è una delle classi previste dal Regolamento CLP (CE) n. 1272/2008. In questa pagina trovi cosa significa, le categorie, il pittogramma e l'avvertenza associati e un elenco di sostanze con questa classificazione armonizzata, ciascuna collegata alla propria scheda.

Che cos'è la classe Flam. Gas

«Gas infiammabile» è la denominazione della classe di pericolo: indica il tipo di pericolo che la sostanza presenta. La gravità è espressa dalla categoria (ad esempio 1, 1A, 1B, 2, 3): più basso è il numero, maggiore è il pericolo. A ogni categoria corrispondono un'indicazione di pericolo (codice H), un pittogramma e un'avvertenza.

Categorie della classe Flam. Gas

Tra le sostanze con classificazione armonizzata in questa classe sono presenti le seguenti categorie:

Pittogramma e avvertenza

Per questa classe, sull'etichetta CLP compaiono tipicamente i seguenti pittogrammi, con l'avvertenza Pericolo:

• GHS02 – Fiamma (infiammabili)
• GHS04 – Bombola per gas (gas sotto pressione)
• GHS08 – Pericolo per la salute (CMR, sensibilizzanti respiratori, aspirazione, STOT)

Obblighi pratici

Se un prodotto contiene una sostanza di questa classe sopra le soglie pertinenti, la classificazione si riflette su etichetta CLP (pittogramma, avvertenza, indicazioni H, consigli P), scheda dati di sicurezza (sezioni 2 e 15), imballaggio ed eventuale notifica al centro antiveleni. Per le miscele il contributo dipende dalla concentrazione e da eventuali limiti specifici o fattori M.

Altre classi di pericolo fisico

Il CLP raggruppa le classi in pericoli fisici, per la salute e per l'ambiente. Altre classi del gruppo «fisico»:

• Esplosivo instabile (Unst. Expl.)
• Esplosivo (Expl.)
• Gas sotto pressione (Press. Gas)
• Liquido infiammabile (Flam. Liq.)
• Solido infiammabile (Flam. Sol.)
• Sostanza o miscela autoreattiva (Self-react.)
• Liquido piroforico (Pyr. Liq.)
• Solido piroforico (Pyr. Sol.)
• A contatto con acqua libera gas infiammabili (Water-react.)
• Perossido organico (Org. Perox.)

Domande frequenti

Come faccio a sapere se una sostanza rientra in questa classe?

Si controlla la sua classificazione: nelle schede per sostanza trovi i codici di classe e categoria di pericolo tratti dall'Allegato VI del CLP, oppure si applica l'autoclassificazione sulla base dei dati disponibili.

Questa classe richiede un pittogramma in etichetta?

Sì, quando previsto dalla categoria: in etichetta CLP vanno riportati pittogramma, avvertenza, indicazioni di pericolo (H) e consigli di prudenza (P) coerenti con la classificazione.

Dove ritrovo l'elenco completo delle sostanze gas infiammabile?

In questa pagina trovi gli esempi collegati alle schede; l'elenco completo è nell'archivio delle schede CLP per sostanza.

La classificazione può cambiare nel tempo?

Sì: gli ATP (adeguamenti al progresso tecnico) aggiornano l'Allegato VI. Verifica sempre la versione consolidata vigente e l'inventario C&L dell'ECHA.
