Uncontrolled Gut Renovation in a 1958 Rental
You are the site supervisor for a kitchen and bath gut renovation of a 1958 single-family rental house. The four-person crew has removed cabinets and drywall and is prying up 9 in. by 9 in. sheet vinyl flooring and black mastic in the kitchen. In the bath, a worker is sanding door jambs and window trim with a random-orbit sander; the paint is chipping. To reach the roof to inspect a leak, a worker sets a 28 ft extension ladder at about 60 degrees and climbs without fall protection. On the second floor, a 30 in. by 40 in. opening to the basement is uncovered. Debris is being thrown from a second-floor window into a dumpster. No one has sampled the flooring or paint; the owner says the house is 'too old to matter.' A neighbor calls MIOSHA. The general contractor has a written safety program but no competent person on site.
1. List the immediate MIOSHA construction hazards and the corrections needed to continue work.

The most serious hazard is fall exposure. The worker on the 28 ft extension ladder is above 6 ft and has no fall protection. The ladder is set at about 60 degrees, which is too shallow; extension ladders should be set at roughly a 4:1 ratio, about 75 degrees, secured at the top, and extended at least 3 ft above the landing. If the roof work requires walking on the roof, use personal fall arrest or guardrails, not just a ladder.
The 30 in. by 40 in. floor opening must be guarded with a standard railing or covered with a secured, labeled cover capable of carrying the expected load. Throwing debris from a second-floor window is prohibited; use a chute or lower debris in containers. Housekeeping must keep walk paths clear, and the crew needs eye, hand, and respiratory protection for the dust-generating tasks.
The lack of a competent person is itself a program failure. The competent person should stop work, correct the fall and opening hazards first, then inspect the site daily. The GC should document the corrections and not let the crew resume until the ladder, opening, and debris controls are in place.
2. What lead and asbestos steps are required before demolition and sanding continue?
Read the worked answer
Stop the sanding and flooring removal until the materials are evaluated. The house was built in 1958, so lead-based paint is presumed until testing shows otherwise. Dry sanding chipping paint creates lead dust. Because this is a rental rather than the owner's own home, the lead-safe renovation rules are likely to apply. Disturbing more than 6 sq ft of interior painted surface generally triggers firm certification, a certified renovator, containment, worker training, HEPA vacuuming, wet methods, and clearance. Dry sanding with a random-orbit sander is not an acceptable lead-safe method.
The 9 in. by 9 in. vinyl flooring and black mastic are suspect asbestos-containing materials. Do not pry or grind them until samples are collected by an accredited inspector and analyzed by a qualified laboratory. If the materials contain asbestos, use a licensed asbestos abatement contractor with wet methods, enclosure, respiratory protection, and proper disposal. If the project meets the regulatory thresholds, provide any required notification to the state air quality agency before renovation.
The owner's statement that the house is 'too old to matter' is backwards. Older materials are more likely to contain lead and asbestos. The GC should issue a stop-work notice, document the suspect materials, and require testing and a written compliance plan before work resumes.
3. What should the GC do about the written safety program and the competent person?
Read the worked answer
A written program is not a substitute for site enforcement. The GC should designate a competent person with authority to stop work, conduct daily inspections, correct hazards, and train the crew. The competent person should document the inspections, including fall protection, ladder setup, floor openings, housekeeping, respiratory protection, and waste handling.
The GC should also hold a stand-down meeting before work resumes. The meeting should cover the specific hazards found: unprotected roof access, the unguarded basement opening, throwing debris, and uncontrolled lead and asbestos dust. Workers should be trained on the lead-safe and asbestos procedures, and the GC should keep training records. The owner and any subcontractors should receive written notice that work will not continue until the hazards are corrected.
Finally, the GC should review its subcontractor agreements. The electrical, demolition, and flooring subs should have the required licenses and certifications, and the GC should not rely on the owner to manage compliance. If a citation follows, the GC's documentation of the stop-work, correction, and training will matter.
