03 · GHS classification
Dialifor hazard classification
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
Dialifor pictograms and signal word
Dialifor hazard class and category
| Hazard class | Category | From code | Pictogram |
|---|---|---|---|
| Acute toxicity - oral GHS chapter 3.1 | Category 1 or 2 | H300 | GHS06 |
| Acute toxicity - dermal GHS chapter 3.1 | Category 3 | H311 | GHS06 |
| Hazardous to the aquatic environment - acute GHS chapter 4.1 | Category 1 | H400 | GHS09 |
| Hazardous to the aquatic environment - chronic GHS chapter 4.1 | Category 1 | H410 | GHS09 |
Where two values are shown with “or”, the hazard statement is shared by more than one category or by more than one class, and the code alone does not say which. H272, for example, belongs to oxidising liquids and to oxidising solids — the physical state decides. The binding answer for a specific entry is in the CLP Annex VI table itself.
Dialifor hazard statements (H-codes)
| Code | Hazard statement |
|---|---|
| H300 | Fatal if swallowed. |
| H311 | Toxic in contact with skin. |
| H400 | Very toxic to aquatic life. |
| H410 | Very toxic to aquatic life with long lasting effects. |

Safety Data Sheet
Getting an SDS for Dialifor
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Dialifor issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
04 · Precautionary statements
Dialifor precautionary statements
CLP Annex VI assigns 10 precautionary statements to Dialifor. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.
Prevention
What to do before and during handling so the hazard never happens.
Response
What to do once exposure, spillage or fire has already happened.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
Dialifor name in 23 EU languages
CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

Dialifor health hazards and exposure limits
Dialifor hazard summary
A cholinesterase inhibitor; [Hawley] A mild skin and eye irritant; In an exposure of 120 vineyard workers, symptoms included dizziness, weakness, headache, blurred vision, and tightness in the chest; Most plasma and red cell values were depressed more than 60%. All fully recovered, although 85 received medical attention and three were hospitalized; [HSDB] Some evidence of reproductive effects in feeding study with hamsters; [RTECS] No adverse gross or histopathological observations in three generation oral study with rats; No teratogenic effects observed in two studies with rabbits and one with macaques; No evidence of mutagenicity; No clinical observations of neurotoxicity in study with birds; Mildly irritating to skin and eyes of rabbits; Effects in high-dose feeding studies with rodents include cholinesterase inhibition and some evidence of liver necrosis; No significant effects observed in gross, histopathological, or tumor frequency in long term feeding studies with rats; [INCHEM JMPR] The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline. [TLVs and BEIs]

Dialifor reactivity
Releases nitrogen oxides, sulfur oxides, and phosphorus oxides when heated. Readily hydrolyzed by concentrated alkali. Avoid alkali. [EPA, 1998]. Organophosphates, such as DIALIFOR, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
