Applicant's summary and conclusion

Conclusions:
The cut-off value for classification of substances for acute inhalation toxicity for gases is LC50= 20 000 ppm (v/v). All published data for chloroethylene report LC50 values higher than 20 000 ppm.
It is, therefore, considered that chloroethylene is of low acute toxicity in experimental animals by inhalation.
