Sample MS Carpentry Practice Questions

1Under OSHA 1926.501, when must a carpenter on a walking/working surface with an unprotected side or edge be protected from falling by a guardrail, safety net, or personal fall arrest system?
A.When the fall distance is 6 feet or more to a lower level
B.Only when the fall distance is 10 feet or more
C.Only when the fall distance is 4 feet or more, the general-industry walking-surface trigger
D.Only when the worker requests fall protection in writing
Explanation: OSHA 1926.501 requires fall protection on construction walking/working surfaces with an unprotected side or edge 6 feet or more above a lower level. Guardrail systems, safety nets, or personal fall arrest systems are the prescribed methods. The 10-foot trigger applies to scaffolds under 1926.451, not to general carpentry edges.
2What is the required top-edge height of an OSHA construction guardrail system above the walking/working surface?
A.36 inches, plus or minus 2 inches
B.42 inches, plus or minus 3 inches
C.48 inches exactly
D.30 inches, plus or minus 3 inches
Explanation: OSHA 1926.502(b) requires the top edge of a guardrail to be 42 inches, plus or minus 3 inches, above the walking/working level. Midrails are installed about halfway between the top rail and the surface. The 36-inch figure is a common residential finished-guard height, not the OSHA construction rail.
3An OSHA construction guardrail top rail must resist which minimum force applied within 2 inches of the top edge in any outward or downward direction?
A.50 pounds
B.100 pounds
C.200 pounds
D.5,000 pounds
Explanation: OSHA 1926.502(b)(3) requires a guardrail system to withstand at least 200 pounds applied within 2 inches of the top edge, outward or downward, at any point along the top. After that downward load, the top edge must not deflect below 39 inches. Five thousand pounds is the personal-fall-arrest anchorage figure, not the rail test.
4A 16-inch by 20-inch floor opening is covered while framing continues. Which OSHA 1926.502 cover practice is required?
A.The cover may be loose cardboard if someone is posted as a monitor
B.The cover must support at least twice the weight that may be imposed, be secured against displacement, and be color coded or marked HOLE or COVER
C.Any plywood scrap is acceptable if it is larger than the hole
D.The cover must support the live load of the finished floor only and need not be marked
Explanation: OSHA 1926.502(i) requires hole covers to support at least twice the weight of employees, equipment, and materials that may be imposed; to be secured against wind, equipment, or workers displacing them; and to be color coded or marked HOLE or COVER. Cardboard, unmarked scraps, and unmarked one-times-live-load lids do not meet those criteria.
5A portable extension ladder reaches a landing 20 feet above the base support. Approximately how far out from the wall should the base be set under OSHA 1926.1053?
A.2 feet
B.5 feet
C.8 feet
D.10 feet
Explanation: OSHA 1926.1053 requires a non-self-supporting ladder to be used so the horizontal distance from the top support to the foot is about one-quarter of the working length—the 4-to-1 rule. For a 20-foot working height, the base is about 5 feet out. A steeper 2-foot set can tip backward; 8 or 10 feet is too flat and overloads the lower rails.
6When a portable ladder is used to reach an upper landing, how far must the side rails extend above that landing unless the ladder is secured and a grab device is provided?
A.1 foot
B.2 feet
C.3 feet
D.6 feet
Explanation: OSHA 1926.1053 requires portable-ladder side rails to extend at least 3 feet above the upper landing surface used for access. That projection gives the worker a handhold while stepping on or off. Shorter projections are a frequent jobsite shortcut and a common citation.
7A carpenter is working on a supported scaffold platform. At what height above a lower level does OSHA 1926.451 require fall protection on that scaffold?
A.4 feet
B.6 feet, the same as general construction edges
C.More than 10 feet
D.15 feet, the steel-erection trigger
Explanation: OSHA 1926.451(g)(1) requires each employee on a scaffold more than 10 feet above a lower level to be protected from falling. That scaffold-specific trigger is higher than the 6-foot Subpart M rule for unprotected building edges. Applying only the 6-foot edge rule, or waiting until 15 feet, misstates Subpart L.
8Which pair of OSHA scaffold rules is correct for a typical supported frame scaffold?
A.The scaffold must support its own weight plus 2 times the intended load, and it may be free-standing at any height
B.The scaffold must support its own weight plus at least 4 times the maximum intended load, and a height-to-base-width ratio more than 4:1 requires guys, ties, or braces
C.The scaffold must support 5,000 pounds per bay, and ties are required only above 20 feet
D.The scaffold must support the intended load with no safety factor if a competent person inspected it
Explanation: OSHA 1926.451 requires each scaffold and component to support its own weight and at least four times the maximum intended load. Supported scaffolds with a height-to-base-width ratio greater than 4:1 must be restrained from tipping by guying, tying, bracing, or equivalent means. Inspection does not waive the capacity or stability rules.
9Unless it is designed as part of a complete personal fall arrest system with a safety factor of at least two, an OSHA personal-fall-arrest anchorage must be capable of supporting how much per attached employee?
A.200 pounds
B.1,800 pounds
C.5,000 pounds
D.10,000 pounds
Explanation: OSHA 1926.502(d)(15) requires a personal-fall-arrest anchorage to support at least 5,000 pounds per employee attached, or to be designed, installed, and used as part of a complete system that maintains a safety factor of at least two. Guardrail 200-pound loading is not an arrest-anchor criterion. Never tie off to an unrated fascia, truss plate, or random 2x block.
10When must erected concrete shoring equipment be inspected on a carpentry/formwork crew, per OSHA 1926.703?
A.Only after the pour is finished and the crew is stripping
B.Immediately prior to, during, and immediately after concrete placement
C.Once, when the forms are first delivered to the site
D.Only if the pour height exceeds 8 feet
Explanation: OSHA 1926.703 requires erected shoring to be inspected immediately prior to, during, and immediately after concrete placement. Damaged or displaced equipment must be immediately repaired or reinforced. Delivery inspection alone, or waiting until strip-out, misses the period when fresh-concrete loads are actually on the system.
