EPA Section 608 Technician Certification — Questions and Answers

Question 1: What documentation must a EPA 608 professional maintain when performing installations?

Installation records including specifications, materials used, and quality verification (Correct answer)
Only a final completion certificate
Personal notes in an informal journal
Documentation is optional for routine installations

Correct answer: Installation records including specifications, materials used, and quality verification

Complete installation records including specifications, materials used, and quality verification are essential for compliance, warranty claims, and future maintenance reference.

Question 2: What should an effective professional report include?

Clear objectives, methodology, findings, analysis, and actionable recommendations (Correct answer)
As much raw data as possible without summary
Personal opinions without supporting data
Only the data tables without interpretation

Correct answer: Clear objectives, methodology, findings, analysis, and actionable recommendations

An effective professional report includes clearly stated objectives, transparent methodology, organized findings, thorough analysis, and specific actionable recommendations.
