# SECTION I: REGULATORY FRAMEWORK & STANDARDS
## Question 1
Which federal regulation contains the primary scaffold safety requirements for construction?
A) 29 CFR 1910 (General Industry)
B) 29 CFR 1926 Subpart L (Scaffolds)
C) 29 CFR 1926 Subpart M (Fall Protection)
D) ANSI A10.8
**Correct Answer: B**
**Rationale:** 29 CFR 1926 Subpart L (§1926.450–§1926.454) is OSHA's construction scaffold
standard. 29 CFR 1910 covers general industry (different rules), Subpart M covers fall protection
generally, and ANSI A10.8 is a national consensus standard, not the regulatory source.

## Question 2
What is the minimum required safety factor for scaffold load capacity according to OSHA?
A) 2:1 ratio
B) 3:1 ratio
C) 4:1 ratio
D) 5:1 ratio
**Correct Answer: C**
**Rationale:** OSHA requires a 4:1 safety factor for scaffold load capacity, meaning the
scaffold must support at least four times its maximum intended load. This ensures a margin of
safety for material defects, dynamic loads, and deterioration.

## Question 3
Which Virginia agency is primarily responsible for enforcing scaffolding safety standards?
A) Virginia Department of Transportation (VDOT)
B) Virginia Department of Labor and Industry (DOLI) - VOSH
C) Virginia Department of Environmental Quality (DEQ)
D) Virginia Board of Contractors
**Correct Answer: B**
,Page 3 of 172
**Rationale:** The Virginia Occupational Safety and Health (VOSH) program, housed within
the Virginia Department of Labor and Industry (DOLI), enforces occupational safety and health
standards for workers in construction, including scaffolding regulations.

## Question 4
What is the maximum height at which a supported scaffold can be erected before guardrails are
required on all open sides?
A) 6 feet
B) 8 feet
C) 10 feet
D) 15 feet
**Correct Answer: C**
**Rationale:** Supported scaffolds over 10 feet in height must have guardrails on all open sides
to prevent falls. This requirement also applies to rolling scaffolds of similar heights.
---
## Question 5
How often must scaffolds be inspected according to OSHA standards?
A) Monthly
B) Before each work shift and after any event affecting structural integrity
C) Once a week
, Page 4 of 172
D) Annually
**Correct Answer: B**
**Rationale:** Scaffolds must be inspected by a competent person before each work shift and
after any event that could affect structural integrity, such as severe weather, impact, or
modifications.

## Question 6
Which OSHA standard specifically addresses training requirements for scaffold erectors and
users?
A) 29 CFR 1926.451
B) 29 CFR 1926.452
C) 29 CFR 1926.453
D) 29 CFR 1926.454
**Correct Answer: D**
**Rationale:** 29 CFR 1926.454 covers scaffolding training requirements. Section 1926.451
covers general requirements, 1926.452 covers additional requirements for specific types of
scaffolds, and 1926.453 covers aerial lifts.
