Safety and Regulations Flashcards

A Maryland renovator is replacing window trim in a pre-1978 house. The homeowner provides a certified lead inspection report showing the specific window trim tested 'negative' for lead. The homeowner also signs a personal written waiver asking the contractor to skip all lead-safe work practices to save cost. Which statement is CORRECT under the EPA Lead RRP Rule?

Answer: Lead-safe practices are not required for the components documented as lead-free by a certified inspector, but the homeowner's personal waiver has no independent legal effect

Under the EPA RRP Rule, if a certified inspector or risk assessor has tested and found specific components to be lead-free, the renovator is not required to use lead-safe work practices on those particular components. However, the homeowner's personal waiver carries no independent legal weight — EPA eliminated the owner opt-out provision in a 2010 rule amendment. The valid exemption here is the certified component-specific test result, not the owner's signature. Choice D is also wrong because the negative test result does legitimately exempt those tested components.

A Maryland home improvement contractor is installing a perimeter drainage system and excavates a trench 7 feet deep. A competent person classifies the soil as Type C (granular, subject to water seepage). The contractor elects to use sloping as the protective method. What is the MINIMUM allowable slope expressed as horizontal distance to vertical depth under OSHA 29 CFR 1926, Subpart P, Appendix B?

Answer: 1½:1 (1.5 feet horizontal per 1 foot vertical)

OSHA Subpart P Appendix B establishes maximum allowable slopes by soil type: Type A (most stable) = ¾:1, Type B (medium stability) = 1:1, and Type C (least stable — granular, layered, or water-affected soils) = 1½:1. For this 7-foot Type C trench, sloping walls must angle back at least 10.5 feet horizontally from the base on each side. Applying a Type B slope (1:1) to Type C soil is a common and dangerous error because it underestimates the cave-in risk of unstable material.

A drywall subcontractor completes work on a Maryland residential addition on April 10 and submits invoices that go unpaid. The general contractor later defaults. Under Maryland Real Property Article §9-104, by what date must the subcontractor serve written Notice of Intention to claim a mechanic's lien in order to preserve lien rights?

Answer: August 8 (120 days after last work)

Maryland Real Property Article §9-104 requires subcontractors to serve a written Notice of Intention to claim a mechanic's lien within 120 days after last furnishing labor or materials — 120 days from April 10 is August 8. Missing this deadline extinguishes lien rights entirely. A critical distinction: general contractors have 180 days to file the actual lien petition with the circuit court, but subcontractors must clear the earlier 120-day preliminary notice hurdle first. Confusing these two deadlines is a common and costly mistake.

A home improvement crew is applying a chemical paint stripper containing methylene chloride at a residential job site. The employer keeps all Safety Data Sheets (SDSs) stored at the company office 18 miles away. Under OSHA's Hazard Communication Standard (29 CFR 1910.1200), which requirement is MOST directly violated by this arrangement?

Answer: Employees' right to immediately access SDS information during their work shift in their work area is violated

OSHA HazCom Standard §1910.1200(g)(8) requires employers to ensure employees can immediately obtain Safety Data Sheets for hazardous chemicals in their work areas during their work shifts. Storing SDSs 18 miles away at a remote office directly violates this accessibility requirement. While medical surveillance (C) is also required under OSHA's specific methylene chloride standard for exposed workers, the scenario described — SDS stored off-site — is a clear and direct HazCom violation. Process Safety Management (D) applies to highly hazardous chemicals in large threshold quantities at fixed industrial facilities, not residential renovation sites.

A Maryland home improvement contractor renovating a kitchen has employees using corded power tools plugged into the home's existing 20-amp receptacles. Under OSHA's electrical safety standards for construction (29 CFR 1926.404), which approach satisfies the GFCI protection requirement?

Answer: The contractor may implement a written Assured Equipment Grounding Conductor Program (AEGCP) as a documented alternative to GFCI devices

OSHA 1926.404(b)(1) requires GFCI protection for all 120-volt, single-phase, 15- and 20-ampere receptacle outlets used on construction sites OR the implementation of an Assured Equipment Grounding Conductor Program. An AEGCP requires a written program, regular visual inspection of cords and tools before each use, and documented continuity and resistance testing. While existing residential GFCI outlets (A) could satisfy the requirement if confirmed functional and properly wired, this cannot be assumed without verification. GFCI rules (C) explicitly cover both 15- and 20-amp circuits. The 6-foot water proximity rule (D) is not an OSHA threshold.

A Maryland homeowner signs a $22,000 bathroom remodel contract at her home on a Saturday afternoon. The meeting occurred because SHE called the contractor's office to request an estimate. On Monday morning — two business days later — she calls to cancel due to changed finances. The contractor argues she has no cancellation right because she was the one who initiated contact. Under the FTC Cooling-Off Rule (16 CFR Part 429), what is the CORRECT legal outcome?

Answer: The homeowner has a valid 3-business-day right to cancel because the rule applies whenever a contract is signed at the consumer's residence, explicitly including situations where the buyer invited the seller

The FTC Cooling-Off Rule (16 CFR §429.0) defines a covered door-to-door sale as one 'in which the seller personally solicits the sale, including those in response to or following an invitation by the buyer.' The statutory language explicitly includes situations where the consumer called the seller first. What triggers the 3-business-day right is WHERE the contract was signed — at the consumer's residence — not who initiated contact. The homeowner's Monday cancellation falls within the 3-day window. The contractor's argument, though commonly made, is legally incorrect under this rule. Cooling-off rights also apply to service contracts, not just goods.
