03 · GHS classification

Ethidium Bromide hazard classification

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

Ethidium Bromide hazard class and category

GHS hazard classes Ethidium Bromide falls into
Hazard class Category From code Pictogram
Acute toxicity - oral GHS chapter 3.1 Category 4 H302 GHS07
Acute toxicity - inhalation GHS chapter 3.1 Category 1 or 2 H330 GHS06
Germ cell mutagenicity GHS chapter 3.5 Category 2 H341 GHS08

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 Ethidium Bromide

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 Ethidium Bromide 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

Ethidium Bromide precautionary statements

CLP Annex VI assigns 12 precautionary statements to Ethidium Bromide. 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

Ethidium Bromide 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.

Ethidium Bromide storage conditions

Ethidium bromide should be handled in the laboratory using the "basic prudent practices" described in Chapter 5.C. Because of its mutagenicity, stock solutions of this compound should be prepared in a fume hood, and protective gloves should be worn at all times while handling this substance. Operations capable of generating ethidium bromide dust or aerosols of ethidium bromide solutions should be conducted in a fume hood to prevent exposure by inhalation.

10 · Questions

Ethidium Bromide — frequently asked questions

What is the CAS number of Ethidium Bromide?

The CAS number of Ethidium Bromide is 1239-45-8. Its EC number is 214-984-6.

What does a Ethidium Bromide label have to show?

Under CLP Annex VI the label for Ethidium Bromide carries the pictograms Skull and crossbones and Health hazard and the signal word is Danger.

Is Ethidium Bromide flammable?

CLP Annex VI assigns Ethidium Bromide 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), above this value (ICSC).

Is Ethidium Bromide a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Ethidium Bromide. 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 Ethidium Bromide?

The melting point reported for Ethidium Bromide is 261 °C (501.8 °F), range, midpoint shown (HSDB).

How should Ethidium Bromide be stored?

Ethidium bromide should be handled in the laboratory using the "basic prudent practices" described in Chapter 5.C. Because of its mutagenicity, stock solutions of this compound should be prepared in a fume hood, and protective gloves should be worn at all times while handling this substance. Operations capable of generating ethidium bromide dust or aerosols of ethidium bromide solutions should be conducted in a fume hood to prevent exposure by inhalation.
