NEWEST ENVIRONMENTAL ANALYTICAL
TECHNOLOGIST CERTIFICATION EXAM
OFFERED BY THE NATIONAL REGISTRY OF
CERTIFIED CHEMISTS (NRCC) | COMPLETE
EXAM Q&A WITH RATIONALES
1. What is the primary purpose of a Chemical Hygiene
Plan (CHP) in an environmental laboratory?
A) To schedule laboratory work shifts
B) To minimize chemical exposure risks and ensure
safe laboratory practices
C) To document laboratory results
D) To store chemical reagents
Correct answer: B
Rationale: A Chemical Hygiene Plan outlines
procedures and responsibilities for minimizing
chemical hazards, ensuring worker safety, and
compliance with OSHA requirements .
2. According to OSHA, which of the following is
required when handling concentrated acids in the
laboratory?
A) Only gloves
,B) Full PPE, including safety goggles, gloves, and lab
coat
C) No protection needed
D) Only a mask
Correct answer: B
Rationale: OSHA mandates full PPE when handling
hazardous chemicals to protect against spills,
splashes, and inhalation risks .
3. What is the correct action if a chemical spill occurs
on the skin?
A) Wipe off with a dry cloth
B) Flush immediately with copious amounts of water
using the safety shower
C) Apply lotion
D) Ignore unless pain occurs
Correct answer: B
Rationale: Immediate flushing with water using the
safety shower reduces chemical absorption and
harm .
4. Which document provides detailed information on
chemical hazards and safe handling procedures?
,A) Chain-of-custody form
B) Safety Data Sheet (SDS)
C) Laboratory logbook
D) EPA declaration form
Correct answer: B
Rationale: SDS contains essential information about
chemical hazards, safe handling, emergency
procedures, and first aid .
5. When labeling hazardous chemical waste, what
must be included?
A) Only the chemical name
B) Chemical name, date, hazard class, and
responsible person
C) Container color only
D) Lab supervisor's initials
Correct answer: B
Rationale: Correct labeling ensures proper
identification, storage, and disposal according to
regulations .
6. What is the primary difference between quality
assurance (QA) and quality control (QC)?
, A) QA ensures processes are followed; QC verifies
results meet specifications
B) QA is only for documentation; QC is for equipment
maintenance
C) QA is about data storage; QC is about data
collection
D) QA is performed by managers; QC by technicians
Correct answer: A
Rationale: QA focuses on preventing problems
through proper processes; QC detects problems by
testing and verification .
7. What is the purpose of a chain-of-custody (COC)
form?
A) To track sample handling from collection to
analysis
B) To order laboratory supplies
C) To calculate detection limits
D) To record staff attendance
Correct answer: A
Rationale: COC ensures sample integrity by tracking
its handling from collection to analysis .
