03 · GHS classification

Phosalone hazard classification

Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.

Phosalone hazard class and category

GHS hazard classes Phosalone falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 3 H301 GHS06
Acute toxicity - dermal GHS chapter 3.1 Category 4 H312 GHS07
Acute toxicity - inhalation GHS chapter 3.1 Category 4 H332 GHS07
Skin sensitisation GHS chapter 3.4 Category 1 or 1A or 1B H317 GHS07
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.

Safety Data Sheet

Getting an SDS for Phosalone

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 Phosalone 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

Phosalone precautionary statements

CLP Annex VI assigns 18 precautionary statements to Phosalone. 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.

Disposal

05 · Names in the regulation

Phosalone 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.

07 · Health hazards

Phosalone health hazards and exposure limits

Phosalone hazard summary

A skin, eye, and respiratory tract irritant; Can be absorbed through skin; A weak cholinesterase inhibitor; [ICSC] Effects in animal studies include zonal hepatitis; [RTECS] May cause skin sensitization; [eChemPortal: ESIS] 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]

Phosalone carcinogenicity classification

Cancer Classification: Not Likely to be Carcinogenic to Humans

Source: Hazardous Substances Data Bank (HSDB)

An IARC group and a CLP classification answer different questions. IARC judges whether the evidence for cancer in humans is strong enough; CLP Annex VI is the legally binding EU classification. A substance can carry one and not the other.

11 · Questions

Phosalone — frequently asked questions

What is the CAS number of Phosalone?

The CAS number of Phosalone is 2310-17-0. Its EC number is 218-996-2.

What does a Phosalone label have to show?

Under CLP Annex VI the label for Phosalone carries the pictograms Skull and crossbones and Environment and the signal word is Danger.

Is Phosalone flammable?

CLP Annex VI assigns Phosalone no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it. The flash point reported for it is 100 °C (212 °F) (ICSC).

Is Phosalone a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Phosalone. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.

What is the melting point of Phosalone?

The melting point reported for Phosalone is 47.75 °C (118 °F), range, midpoint shown (HSDB).

How should Phosalone be stored?

Do not store below 32 °F. Do not ... store with plants, seeds or foodstuffs. (Hazardous Substances Data Bank (HSDB))
