Master Plumber Exam Business Operations & Law 5 — Questions and Answers
Question 1: A plumbing contractor's employee is injured on a job site. The contractor carries workers' compensation insurance. Which statement is correct?
- The injured employee can sue the contractor for negligence in addition to filing a WC claim
- Workers' compensation is the exclusive remedy; the employee generally cannot sue the employer (Correct answer)
- The contractor's general liability policy pays first, then WC covers the remainder
- The employee must prove employer negligence to receive benefits
Correct answer: Workers' compensation is the exclusive remedy; the employee generally cannot sue the employer
Workers' compensation is a no-fault, exclusive-remedy system; employees receive statutory benefits but generally waive the right to sue the employer for workplace injuries.
Question 2: What is the purpose of a 'Notice to Owner' (or equivalent preliminary notice) in construction lien law?
- To inform the owner that the contractor has obtained a permit
- To preserve a subcontractor's or supplier's right to file a mechanics lien if unpaid (Correct answer)
- To officially begin the statute of limitations for lien filing
- To notify the owner of job site hazards
Correct answer: To preserve a subcontractor's or supplier's right to file a mechanics lien if unpaid
A preliminary notice alerts the owner that a subcontractor or supplier is furnishing labor or materials and preserves their lien rights under many state statutes.
Question 3: An employer classifies all plumbers as independent contractors to avoid paying payroll taxes. The IRS audits and reclassifies them as employees. The primary penalty is:
- Loss of the contractor's plumbing license
- Back payroll taxes, interest, and potential penalties for all reclassified workers (Correct answer)
- Forfeiture of all project revenue for the audit period
- Automatic enrollment in a federal apprenticeship program
Correct answer: Back payroll taxes, interest, and potential penalties for all reclassified workers
Misclassifying employees as independent contractors exposes the employer to back employment taxes (FICA, FUTA), interest, and IRS penalties.
Question 4: A master plumber is asked to sign a contract clause that shifts all project risk — including the owner's own negligence — to the plumber. This is known as a:
- Liquidated damages clause
- Broad-form indemnification clause (Correct answer)
- Consequential damages waiver
- Force majeure clause
Correct answer: Broad-form indemnification clause
A broad-form indemnification clause requires one party to indemnify another for losses including those caused by the indemnitee's own negligence, and is prohibited or limited in many states.
Question 5: Which government agency administers the Occupational Safety and Health Act and can inspect plumbing job sites?
- EPA (Environmental Protection Agency)
- OSHA (Occupational Safety and Health Administration) (Correct answer)
- CPSC (Consumer Product Safety Commission)
- DOT (Department of Transportation)
Correct answer: OSHA (Occupational Safety and Health Administration)
OSHA, under the U.S. Department of Labor, enforces workplace safety standards and has the authority to conduct inspections and issue citations on construction sites.
Question 6: A plumbing contractor wants to bid on a government contract that requires a small business certification. Which federal agency issues the primary small business size certifications?
- IRS (Internal Revenue Service)
- SBA (Small Business Administration) (Correct answer)
- HUD (Department of Housing and Urban Development)
- FTC (Federal Trade Commission)
Correct answer: SBA (Small Business Administration)
The SBA establishes size standards by industry NAICS code and certifies businesses as small for federal contracting purposes.
Question 7: A plumbing company's general liability policy has a $1 million per-occurrence limit and a $2 million aggregate limit. After two $800,000 claims in one year, how much coverage remains for a third claim?
- $1,000,000 — the per-occurrence limit resets each claim
- $400,000 — the aggregate limit has been nearly exhausted
- $200,000 — only the remaining aggregate is available (Correct answer)
- $0 — both limits have been triggered and coverage is exhausted
Correct answer: $200,000 — only the remaining aggregate is available
The aggregate limit ($2M) minus paid claims ($1.6M) leaves $400,000 remaining; however, the per-occurrence cap is $1M, so only $400,000 is available for a third claim.
