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 |
New Existing New New |
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
