Exam Structure
The HAZWOPER 8-Hour Refresher Final Exam for the 2026/2027 recertification cycle is a 25-question,
multiple-choice examination.
Introduction
This HAZWOPER 8-Hour Refresher Exam guide for the 2026/2027 recertification cycle provides updated
content to meet OSHA's annual training requirement. The content focuses on reinforcing core safety
principles, reviewing regulatory changes, refreshing practical response skills, and integrating new
industry knowledge to maintain competency for hazardous waste site workers and emergency responders.
Answer Format
All correct answers and updated safety procedures must be presented in bold and green, followed by
detailed rationales that reference the latest OSHA interpretations, updated exposure limits, recent
incident case studies, and current best practices in hazardous materials response.
1.
According to OSHA 29 CFR 1910.120(e)(8), how often must HAZWOPER-certified workers
complete refresher training?
A. Every 6 months
B. Annually
C. Every 2 years
D. Only after an incident
B. Annually
Rationale (OSHA 29 CFR 1910.120(e)(8)): OSHA mandates that workers who have completed the initial
24- or 40-hour HAZWOPER training must receive at least 8 hours of refresher training annually to
maintain their certification. This ensures continued competency in safety procedures, PPE use, and
emergency response protocols.
, 2.
During an annual PPE inspection, which of the following defects would require immediate
replacement of a self-contained breathing apparatus (SCBA)?
A. Minor scuff on the facepiece lens
B. Cracked regulator housing or damaged hoses
C. Slightly worn harness strap
D. Faded manufacturer label
B. Cracked regulator housing or damaged hoses
Rationale (NIOSH Respirator Inspection Guidelines, 2025 Update): Cracks or damage to the regulator,
hoses, or cylinder connections compromise the integrity of the SCBA and pose an immediate life-safety
risk. OSHA requires thorough pre-use and annual inspections. Any structural defect must result in
immediate removal from service until repaired and certified by a qualified technician.
3.
What is the primary purpose of reevaluating site hazards during an annual refresher
review?
A. To reduce the number of required safety meetings
B. To identify new or changed hazards that may affect PPE selection, zone boundaries, or emergency
procedures
C. To eliminate the need for medical surveillance
D. To decrease the frequency of air monitoring
B. To identify new or changed hazards that may affect PPE selection, zone boundaries, or
emergency procedures
Rationale (OSHA 29 CFR 1910.120(b)(4)(ii)(G)): Site conditions can change due to weather, excavation,
new waste deposition, or chemical reactions. Annual reevaluation ensures the Site Safety and Health Plan
(SSHP) remains accurate and protective. This is reinforced by lessons from the 2024 Norwalk, CA
chemical drum rupture, where unanticipated peroxide formation led to an explosion.
