, Exam Overview & Content Outline
EXAM PURPOSE
Indiana Chemical Laboratory Technician certification covers analytical chemistry, laboratory safety,
instrumentation, quality control, and calculations. Based on ACS, OSHA, EPA, and Indiana
Department of Environmental Management (IDEM) standards for environmental, industrial, and
research laboratories.
CONTENT DISTRIBUTION
• Laboratory Safety & Regulations (25%) — OSHA Lab Standard, SDS, PPE, chemical hygiene,
waste disposal, EPA, IDEM
• Analytical Techniques & Wet Chemistry (25%) — Titrations, gravimetric, pH, conductivity,
sample prep, reagents
• Instrumentation (25%) — UV-Vis, AA, ICP, GC, HPLC, calibration, maintenance, troubleshooting
• Quality Control & Data Analysis (15%) — QC charts, accuracy, precision, LOD, LOQ, statistics,
documentation
• Chemical Calculations & Math (10%) — Molarity, dilutions, ppm/ppb, stoichiometry, significant
figures, unit conversions
QUESTION FORMAT & SCORING
Each item presents four options. Correct answers are highlighted in green with checkmark (✓).
Every question includes detailed rationale with chemical laboratory standards. Indiana/industry
requires 70% to pass technician exam.
STUDY STRATEGY
Master OSHA Lab Standard and chemical hygiene. Know titration calculations and molarity.
Understand instrument principles and calibration. Review QC procedures and statistics. Study waste
disposal per EPA/IDEM. Practice unit conversions and dilutions.
CURRICULUM ALIGNMENT
Questions reflect 2026-2027 standards: ACS guidelines, OSHA 29 CFR 1910.1450, EPA methods,
IDEM regulations, Standard Methods for Water/Wastewater, and GLP/GMP requirements.

, SECTION I: Laboratory Safety & Regulations
1. OSHA Laboratory Standard 29 CFR 1910.1450 requires:
A. No chemical hygiene plan
✓ B. Written Chemical Hygiene Plan (CHP)
C. Unlimited exposure
D. No PPE
Rationale: OSHA Lab Standard: Requires written Chemical Hygiene Plan (CHP) for labs using hazardous
chemicals. CHP includes SOPs, control measures, PPE, training, medical surveillance, chemical inventory,
waste disposal. Chemical Hygiene Officer designated. Annual review. Protects workers from chemical
exposure.
2. SDS Section 2 contains:
A. First aid measures
✓ B. Hazard identification
C. Physical properties
D. Disposal
Rationale: SDS 16 sections: 1-ID, 2-Hazards, 3-Composition, 4-First Aid, 5-Fire, 6-Accidental Release,
7-Handling/Storage, 8-Exposure Controls/PPE, 9-Physical/Chemical, 10-Stability, 11-Toxicology,
12-Ecological, 13-Disposal, 14-Transport, 15-Regulatory, 16-Other. Section 2: GHS pictograms, signal
word, hazard statements.
3. Acid spill in lab should be neutralized with:
A. Water only
✓ B. Sodium bicarbonate or commercial neutralizer, then water
C. Base directly
D. Organic solvent
Rationale: Acid spill: Neutralize with sodium bicarbonate (baking soda) or commercial spill kit, then absorb
and dispose as hazardous waste. Never add water to concentrated acid (exothermic). Base spill: citric acid
or commercial neutralizer. PPE required. Report per CHP.
4. Fume hood face velocity should be:
A. 10 fpm
✓ B. 80-120 fpm
C. 500 fpm
D. 0 fpm
Rationale: OSHA/ANSI: Fume hood face velocity 80-120 fpm (typically 100 fpm) with sash at operating
height. Tested annually. Too low = escape; too high = turbulence. Keep sash low, no blocking. Not for
storage. Verify airflow before use. Protects from inhalation.
5. Hazardous waste container must be labeled with:
A. No label
