Harmonised classification of dinitrogen oxide: EIGA’s views

The French Authorities submitted a dossier on 10/01/2022 for harmonised classification of dinitrogen oxide.
It was checked and accepted by ECHA on 25 April 2022. The following classification is mentioned in the dossier:

Physical hazards Oxidising Gases, Category 1 H270
Gases under pressure : Refrigerated liquefied gas H281

Repr. 1B, H360Df

STOT SE 3, H336

STOT RE 1, H372

Ozone 1, H420

Reproductive toxicity

Specific target organ toxicity single exposure

Specific target organ toxicity repeated exposure

Hazardous to the ozone layer

During the public consultation period from 16/5/22 to 15/7/22, EIGA entered a comment paper.

RAC published their report on 25/6/23 and is supporting the proposal for harmonised classification.

The proposed harmonised classification and introduction in annex VI of CLP will be discussed by CARACAL on 20/03/24.

EIGA members decided to take further action and send more comments to CARACAL.
We ask the CARACAL to:
• ensure that the hazard classification is not based on overexposure by voluntary abuse;
• review how RAC has chosen to proceed with an opinion since the test method requirements of OECD and ECHA Guideline on CLP are not met;
• question that the same studies lead to different conclusions;
• not accept the deviation from established process and guidelines at the risk of setting precedents.

These comments are also publicly available on circabc: https://circabc.europa.eu/ui/group/a0b483a2-4c05-4058-addf-2a4de71b9a98/library/e7ca3064-c017-4885-8d8d-9ec4bde16645?p=1&n=10&sort=modified_DESC
