Executive summary:

The American Conference of Governmental Industrial Hygienists(ACGIH) is a professional association of industrial hygienists and practitioners of related professions. One of the goals of the association is to provide information and guideline on exposure limits of substances in order to advance worker protection.

ACGIH sheets are based on a review of existing peer-reviewed scientific literature by committees of experts in public health and related sciences and therefore ACGIH is considered a reliable secondary source of information.

According to the ACGIH sheet, only slight irritation was seen when 1,1,2,2-tetrachloro-1,2-difluoroethane was placed in the rabbit eye. (DuPont Company, 1947, 1963).

According to Regulation (EC) No. 1272/2008, 1,1,2,2 -tetrachloro-1,2-difluoroethane does not meet the classification criteria for Serious Eye Damage/Eye Irritation.
