Sample AL Lath Plaster Practice Questions

Try these sample questions to test your AL Lath Plaster exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under OSHA construction fall-protection rules (29 CFR 1926 Subpart M), at what height must workers on unprotected sides and edges generally be protected from falling?
A.4 feet above a lower level
B.6 feet above a lower level
C.10 feet above a lower level
D.15 feet above a lower level
Explanation: OSHA 29 CFR 1926.501 generally requires fall protection when employees are exposed to falls of 6 feet or more to a lower level on construction sites. Guardrails, safety nets, or personal fall-arrest systems are the common compliant methods. Scaffold work has separate Subpart L thresholds, but unprotected edges fall under the 6-foot rule.
2Per OSHA 29 CFR 1926 Subpart L, when must employees working on a scaffold generally be protected from falling?
A.More than 4 feet above a lower level
B.More than 6 feet above a lower level
C.More than 10 feet above a lower level
D.More than 20 feet above a lower level
Explanation: OSHA 1926.451(g) requires each employee on a scaffold more than 10 feet above a lower level to be protected from falling. Guardrails and/or personal fall-arrest systems are required depending on scaffold type. This scaffold-specific 10-foot rule is distinct from the 6-foot Subpart M unprotected-edge rule.
3What is OSHA’s permissible exposure limit (PEL) for respirable crystalline silica in construction as an 8-hour time-weighted average?
A.25 micrograms per cubic meter (μg/m³)
B.50 micrograms per cubic meter (μg/m³)
C.100 micrograms per cubic meter (μg/m³)
D.250 micrograms per cubic meter (μg/m³)
Explanation: OSHA 29 CFR 1926.1153 sets the construction PEL for respirable crystalline silica at 50 μg/m³ as an 8-hour TWA. The action level is 25 μg/m³. Mixing dry portland cement plaster, cutting masonry, or grinding cured stucco can generate silica dust that requires engineering controls, work practices, and sometimes respirators.
4When employees are exposed to falling-object hazards during multi-level lath and plaster work, what PPE does OSHA specifically require employers to provide for head protection?
A.Only safety glasses
B.Hard hats
C.Only face shields
D.Only hearing protection
Explanation: OSHA requires hard hats where employees are exposed to falling or flying objects or other head-impact hazards (29 CFR 1926.100 and related falling-object provisions). On lath and plaster jobs, materials, tools, and debris can fall from scaffolds or upper floors, so head protection is mandatory in those exposures.
5Which control method should be used first to reduce silica dust when dry-mixing portland cement plaster ingredients?
A.Rely only on disposable dust masks chosen by workers
B.Engineering controls and work practices such as local exhaust, water, or enclosed mixing, then PPE if needed
C.Only increase general room fans with no source control
D.Only schedule longer shifts so dust settles overnight
Explanation: OSHA’s hierarchy of controls prioritizes engineering controls and work practices before personal protective equipment. For silica, employers must use methods that keep exposures at or below the PEL—such as wet methods, local exhaust, or controlled mixing—and provide respirators only when those controls are insufficient or as required by the standard.
6What is the primary purpose of a written exposure control plan under OSHA’s respirable crystalline silica standard for construction?
A.To replace all SDS documents on site
B.To describe silica tasks, controls, housekeeping, and restricted-access procedures
C.To list only the brand names of joint compound
D.To eliminate the need for employee training
Explanation: 29 CFR 1926.1153 requires a written exposure control plan that identifies tasks involving silica, the engineering controls and work practices used, housekeeping measures, and procedures to restrict access when needed. The plan is a living jobsite document, not a substitute for SDS sheets or training.
7When working from a scaffold platform while applying exterior stucco, what is the best practice for material staging?
A.Stack bags so they overhang the platform edge for easy access
B.Keep platforms free of debris and stage materials so load capacity and clear working area are maintained
C.Place all materials on one end only, regardless of scaffold design load
D.Store wet plaster mix directly against guardrail posts to brace them
Explanation: OSHA scaffold rules require platforms to be kept clear of debris and loaded within design capacity, with safe access and working room. Overhanging bags, concentrated overloading, or bracing materials against guardrails creates fall, collapse, and tripping hazards during plastering.
8Which hazard is most directly associated with cutting or grinding cured portland cement plaster without dust controls?
A.Lead vapor only
B.Respirable crystalline silica dust
C.Carbon monoxide from the plaster itself
D.Asbestos in all modern stucco mixes
Explanation: Portland cement plaster and many aggregates can generate respirable crystalline silica when cut, ground, or dry-swept after curing. Silica dust is a recognized occupational lung hazard regulated by OSHA 1926.1153. Modern code-compliant stucco does not inherently contain asbestos, and cement plaster does not emit carbon monoxide by itself.
9Before raising a mobile scaffold for exterior lath installation, what must the crew verify?
A.That casters are unlocked so the scaffold can roll freely while occupied
B.That the scaffold is level, fully planked as required, and casters are locked before workers climb
C.That only two diagonal braces are installed on one side
D.That guardrails are optional below 20 feet
Explanation: Mobile scaffolds must be used on firm, level surfaces with casters locked before employees climb. Platforms must be properly planked and fall protection provided per Subpart L. Rolling a scaffold while occupied, incomplete bracing, or omitting required guardrails creates tip-over and fall hazards.
10Which eye and face protection practice is appropriate when mixing dry cementitious plaster products?
A.No eye protection is needed if mixing outdoors
B.Use safety glasses or goggles rated for the dust and splash hazard present
C.Only sunglasses for UV protection
D.Contact lenses alone provide adequate protection
Explanation: Dry cement and lime products can irritate or burn eyes from dust and alkaline splash. OSHA requires suitable eye protection for the hazard. Outdoor work does not remove the need for protection, and contact lenses or fashion sunglasses are not substitutes for safety eyewear.
