Justification for classification or non-classification
Phosphine is listed on Annex VI to Regulation (EC) No 1272/2008 includes lists of harmonised classification and labelling.
On table 3.2 (classification and labelling in accordance with the criteria set up in Annex VI to Directive 67/548/EEC), phosphine is listed with extremely flammable R12 and spontaneously flammable in air R17 (F+, extremely inflammable). No change to this classification is proposed.
On table 3.1 (classification and labelling in accordance with the criteria set up in Annex I to Regulation 1272/2008/EEC), phosphine is listed with extremely flammable gas H220 (Flam. Gas. Category 1). No change to this classification is proposed.
