Daito has implemented the following actions to comply with regulations such as RoHS *1 Directive concerning the use of hazardous materials:

Daito operations are approved for ISO 14001 (Environmental Management Systems) and the company has striven to reduce environmental impacts caused by enterprise activities under the guiding principle of "Environmentally friendly manufacturing and corporate activities".

In 2000, Daito launched the "Lead and Cadmium Free Committee" to promptly and efficiently implement a study and introduction of materials as substitutes for the lead and cadmium contained in its products company-wide and has since taken steps to eliminate such lead and cadmium.

The main materials having impacting on the environment and contained in conventional fuses, fuseholders and other devices are as follows :

Pb (Lead) : Mainly contained in terminal plating and some fuse elements *2
Cd (Cadmium) : Mainly contained in fuse elements *2

*1: Legal regulations concerning "The Restriction of Hazardous Substances in Electric and Electronic Equipment" established by the European Union (EU).
From July 2006 onwards, the sale of products containing six substance groups (Pb[lead], Hg[mercury], Cd[cadmium], Cr6+[hexavalent chrominum], PBB[polybrominated biphenyls] and PBDE[polybrominated diphenyl ether]) in the member countries of EU will be restricted.

*2: So-called fuse wire made of a single metal or alloy. Fuse elements are in wire, thin film or other forms.
