, ethyl ether, petrolic ether, and sodium salicylate, various sulfurous substances.
The supplemental project involves purchasing and installing of a vacuum degreasing unit that uses hydrocarbons instead of ethylene chloride
to clean parts.
It is resistant to hydrochloric, nitric, ethylene chloride
and sulfuric acids, and has also survived long-term salt fog, salt spray and humidity testering of over 1,000 hours.

, =ethylene oxide, lindane and parathion (ethyl-parathion).Regulation 2455/92 outlines provisions concerning the implementation in =the European Union of prior informed consent put in place by the United =Nations Environment Programme (UNEP) and the United Nations Food and =Agriculture Organisation (FAO), regarding the import and export to third =countries of banned or strictly regulated chemicals.
