5、ol of Overhaul Chemical Process Operators (Parts Cleaners) RATIONALEThere is a close relationship between part cleaning and most non-destructive inspection techniques. The FAA requested SAE Committee J to develop and issue a training guideline for chemical process operators in the parts cleaning are

6、a as this is generally considered unskilled labor and in the past, little or no training had been provided or recommended. Since overhaul cleaning is a critical process step prior to visual and fluorescent penetrant inspection processes, consideration must be given to minimum levels of training for

7、these process operators. The FAA plans to refer to this document in future shop audits of the parts cleaning areas. TABLE OF CONTENTS 1. SCOPE 2 1.1 Purpose . 2 2. REFERENCES 2 3.

8、NAL ARP6240 Page 2 of 6 1. SCOPE The task of chemical process operator in the parts cleaning area is generally considered unskilled labor and in the past, little or no training had been provided or recommended. Since overhaul cleaning is a critical process step prior to visual and fluorescent penetr

9、ant inspection processes, consideration must be given to minimum levels of training for these process operators. It is the responsibility of the department supervisor to ensure that all personnel within the department are trained to acceptable level in all general aspects of health and safety and ba

10、sic operating procedures. This document is intended to augment the local quality control system which will control the application and frequency of the guidelines stated within. 1.1 Purpose To provide an outline for training chemical process operators to insure an acceptable level of understanding a

11、nd proficiency within the existing production process system. 2. REFERENCES There are no referenced publications specified herein. 3.
