Section 1: OSHA Subpart R – Steel Erection (29 CFR 1926.750–761)
1. Under OSHA Subpart R (1926.750), what is the definition of a
"connector"?
A) Any employee who is engaged in the final assembly of structural
steel members
B) An employee who is working at heights and connecting structural
steel members
C) An employee who is operating a crane
D) An employee who is welding structural steel
Answer: B) An employee who is working at heights and
connecting structural steel members
Explanation: OSHA 1926.751 defines a connector as an employee who,
working at heights, is connecting structural steel members. Connectors
are required to use fall protection and have specific training
requirements under Subpart R.
,2. According to OSHA 1926.753, what is the minimum distance a
crane must maintain from power lines?
A) 5 feet for lines up to 50 kV
B) 10 feet for lines up to 50 kV
C) 15 feet for all power lines
D) 20 feet for lines over 50 kV
Answer: B) 10 feet for lines up to 50 kV
Explanation: OSHA 1926.1408 requires that equipment maintain a
minimum clearance of 10 feet from power lines up to 50 kV. For lines
over 50 kV, the minimum distance increases by 4 inches for every 10 kV
over 50 kV.
3. Under OSHA 1926.760, when must fall protection be provided
for steel erection activities?
A) When working at heights over 6 feet
B) When working at heights over 10 feet
C) When working at heights over 15 feet
D) When working at heights over 20 feet
Answer: C) When working at heights over 15 feet
Explanation: OSHA Subpart R (1926.760) requires fall protection for steel
erection activities when employees are working at heights of 15 feet or
more above a lower level. This is a lower threshold than the general
construction standard (6 feet).
,4. What is the maximum allowable gap between structural steel
members for a worker to walk without fall protection?
A) 6 inches
B) 12 inches
C) 18 inches
D) 24 inches
Answer: B) 12 inches
Explanation: OSHA 1926.760(b)(2) states that when walking or working
on structural steel members where fall protection is not otherwise
provided, the gap between members cannot exceed 12 inches. Gaps
larger than 12 inches require fall protection.
5. According to OSHA 1926.752, what must be completed before
steel erection begins?
A) A site-specific erection plan
B) A safety meeting
C) A crane inspection
D) A material delivery schedule
Answer: A) A site-specific erection plan
*Explanation: OSHA 1926.752 requires that before steel erection
begins, the controlling contractor must provide a site-specific erection
plan to the steel erector. This plan addresses coordination of crane
operations, sequencing, and safety measures.*
6. Under OSHA 1926.755, what is the requirement for column
anchorage during steel erection?
, A) Columns must be anchored immediately after placement
B) Columns must be anchored within 4 hours of placement
C) Columns must be anchored within 24 hours
D) Columns do not require anchoring until the floor is poured
Answer: A) Columns must be anchored immediately after
placement
Explanation: OSHA 1926.755(a)(1) requires that columns be anchored
immediately after placement. If immediate anchoring is not possible,
columns must be guyed or braced to prevent displacement.
7. What is the minimum number of bolts required to secure a
column before releasing the crane?
A) 1 bolt
B) 2 bolts
C) 4 bolts
D) 8 bolts
Answer: B) 2 bolts
Explanation: OSHA 1926.755(b)(2) requires that at least two bolts be
installed and tightened to secure a column before the crane is released.
This prevents column displacement during erection.
8. According to OSHA 1926.756, what is the requirement for
decking during steel erection?
A) Decking must be installed as soon as possible but within 30 days
B) Decking must be installed immediately after the steel is erected
