The classification of sulfur as phytosanitary was always favorable because non toxic or harmful to the human being, to animals and to environment.

The first classification by Ministry was: IV class, then NOT CLASSIFIED and finally IRRITANT.

Presently the classification of sulfur is regulated according the reg. 1272/2008 CLP with pictograms and risk phrases which are in the specific case:
Pictogram Attention and Risk Phrase H315 causes skin irritation
ASPIZ commissioned a study to the Research Toxicology Center on the skin irritation by sulfur and its formulates which confirmed that sulfur is not irritating for the skin according to the applied methodology Reconstructed Human Epidermis (RhE) Model (EPISKINTM/MTT method)
The Directive 128/2009 about sustainable use of pesticides defines at art.3 point 10 “pesticide”:
a) Phytosanitary product according the rule (CE) n. 1107/2009
Art. 1 reg. 1107/2009 Scope and purpose
1. The present rule establishes norms about authorization, placing on the market, the use and control of the phytosanitary products within the European Community as they are shown in their commercial form.
Substantially phytosanitary and pesticide are synonyms, but not all have the same class of danger. Pesticide got a negative meaning but it is deriving from the English translation “pesticide”.
Among the phytosanitary products (pesticides) sulfur is the one with a very favorable classification because its low impact on the environment and on man. It is demonstrated by the fact that it was always inserted in the phytosanitary defense in Biological Agriculture reg. 2092/91 and reg. 834/2007 modified with the reg. 889/2008 where it is inserted in the annex 1 “Fertilizers and soil improvers (elemental sulfur)” and in the annex 2 “ Phytosanitary products (point 6 copper oxychloride - sulfur ”

The regulation 1107/2009 reports in the annex 2:

5. active substances with low risk

An active substance is not considered at low risk if it is or must be classified (according the rule (CE) n. 1272/2008 ) as follows:
- carcinogenic
- mutagen
- toxic for reproduction – chemical sensitizing
- very toxic or toxic
- explosive
- corrosive

The label of Sulfur and Copper sulfur, authorized by Health Ministry report the only phrases of precaution:
P280 to dress gloves / protective dress for sulfur and
P270 do not eat/drink/smoke during use
P273 do not spread into the environment
P280 to dress gloves and protective dress for copper sulfur

Sulfur is not among these items.

The D. Lgs 81/2008 requires the use of DPI in case of dangerous substances. The prescription by the occupational doctor inside our labor environments regards the use of the dust mask and the gloves (DVR).
For what concerning the eventual fall of sulfur on the ground it does not create any problem but has even a fertilizer nourishing and acidifying function which has nothing to do with the acid rain falls, by now only marginal since the desulphurization of gasoil and gasoline is done.
The report on the use of sulfur as fertilizer presented in Cambridge in 2002 by IFS (International fertilizer Society) is annexed.
Main norms regulating sulfur:
reg. CE n. 1107/2009 (marketing of phytosanitary products)
reg. CE n. 2003/2003 (marketing of fertilizers)
d. lgs n. 75/2010 (marketing of fertilizers) Italian norm
reg. CE n. 889/2008 (with application modality of reg. 834/2007 related to the biological production and labeling of biological products).
