New Harmonised Classification and Labelling Consultation for calcium carbide
The European Chemicals Agency (ECHA) plays a pivotal role in ensuring the safety of chemicals through harmonised classification and labelling (CLH). This process standardizes the hazard classifications across EU Member States, helping industries, regulatory bodies, and the public manage chemical risks effectively.
What is CLH Consultation?
CLH consultations invite stakeholders to comment on proposed hazard classifications for substances. These consultations ensure transparency and encourage the submission of additional scientific data to refine or validate proposed classifications. The process also strengthens regulatory decisions, ensuring they reflect current scientific evidence.

Key Features of Current CLH Consultation
- Substance in Focus: Calcium acetylide (calcium carbide)
- Proposed New Classifications:
- Water-reactive (H260)
- Skin corrosion (H314)
- Eye damage (H318)
- Specific target organ toxicity (H335)
- Open Hazard Classes for Commenting: Ranges from physical hazards to environmental risks, including acute toxicity and carcinogenicity.
- Proposed New Classifications:
- Participation Details:
- Open from September 23, 2024, to November 22, 2024.
- Comments can include general observations, scientific data, or clarifications.
- Stakeholders are encouraged to submit comments supporting or refining the proposed classifications.
Why Participate?
By contributing, stakeholders help:
- Refine scientific assessments.
- Ensure classifications accurately represent the risks.
- Enhance chemical safety for workers, consumers, and the environment.
