The pH of post etch rinse tanks and waste ,treatment, neutralization systems, if allowed to rise too high will result in the release of noxious ,ammonia, fumes. Appropriate precautions should be taken. The sludge generated by the process, although greatly reduced when compared to a conventional caustic etch process, must be removed and disposed of in a manner consistent with local and state agencies.
