03 · GHS classification

Phosphamidon hazard classification

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

Phosphamidon hazard class and category

GHS hazard classes Phosphamidon falls into
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
Germ cell mutagenicity GHS chapter 3.5 Category 2 H341 GHS08
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 Phosphamidon

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 Phosphamidon 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

Phosphamidon precautionary statements

CLP Annex VI assigns 13 precautionary statements to Phosphamidon. 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.

05 · Names in the regulation

Phosphamidon 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.

Phosphamidon health hazards and exposure limits

Phosphamidon hazard summary

An eye irritant; Can be absorbed through skin; A cholinesterase inhibitor that may cause CNS effects resulting in convulsions and respiratory depression; [ICSC] Gamma-Chlorophosphamidon, present as an impurity at a level of 1-2% in the technical product, is approximately 20 times more potent as a human cholinesterase inhibitor; In a human test involving unprotected exposure from aircraft spraying in a paddy field, volunteers experienced immediate eye irritation and depression of plasma cholinesterase by as much as 50%; No evidence of delayed neurotoxicity in hens; [HSDB] 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]

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.

10 · Questions

Phosphamidon — frequently asked questions

What is the CAS number of Phosphamidon?

The CAS number of Phosphamidon is 13171-21-6. Its EC number is 236-116-5.

What is the chemical formula of Phosphamidon?

The molecular formula of Phosphamidon is C10H19ClNO5P and its molecular weight is 299.69 g/mol.

What does a Phosphamidon label have to show?

Under CLP Annex VI the label for Phosphamidon carries the pictograms Skull and crossbones, Health hazard and Environment and the signal word is Danger.

Is Phosphamidon flammable?

CLP Annex VI assigns Phosphamidon 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 93.33 °C (200 °F), above this value (CAMEO).

Is Phosphamidon a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Phosphamidon. 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 boiling point of Phosphamidon?

The boiling point reported for Phosphamidon is 350 °C (662 °F), at 760 mmHg (DOE PAC).

What is the melting point of Phosphamidon?

The melting point reported for Phosphamidon is -45 °C (-49 °F) (HSDB).

How should Phosphamidon be stored?

You should store this material under ambient temperatures. (Hazardous Substances Data Bank (HSDB))
