Question 1Floor Covering Craft Fundamentals

Before installing a resilient sheet floor over a concrete slab, what is the primary reason for performing a moisture vapor emission test?

  1. To measure the slab's thermal expansion coefficient
  2. To confirm the slab has fully cured to its design strength
  3. To determine whether the adhesive bond will be compromised by excess moisture vapor Correct answer.
  4. To verify the concrete mix met the specified aggregate ratio

Explanation

Excess moisture vapor rising through a slab can break down adhesive and cause resilient flooring to bubble or release. A vapor emission test quantifies that moisture so the installer can choose an appropriate vapor retarder or adhesive system before covering the slab.

Question 2Floor Covering Craft Fundamentals

Which tool is used to cut a smooth, straight seam edge on a roll of carpet before seaming?

  1. A seam roller
  2. A knee kicker
  3. A carpet knife guided by a straightedge Correct answer.
  4. A wall trimmer

Explanation

A sharp carpet knife run along a straightedge produces a clean, square seam edge that allows the two pieces to butt tightly. Wall trimmers and knee kickers serve other steps in the installation.

Question 3Floor Covering Craft Fundamentals

What is the standard purpose of a tackless strip in wall-to-wall carpet installation?

  1. To bond the carpet to the subfloor with adhesive
  2. To seal the gap between baseboard and floor
  3. To cushion the carpet at the wall line
  4. To hold the carpet edge and provide a surface for stretching Correct answer.

Explanation

Tackless strip is nailed around the room perimeter with pins angled toward the wall. The carpet is hooked onto the pins and stretched, which holds the edge securely while the cushion sits inside the strip.

Question 4Floor Covering Craft Fundamentals

Which substrate condition must be corrected before installing any resilient tile?

  1. Slight surface dust that will be covered by adhesive
  2. A floor with visible old adhesive residue
  3. A surface with minor high spots under 3 mm
  4. A flat, clean, dry surface free of cracks and contaminants Correct answer.

Explanation

Resilient tile telegraphs substrate defects, so the surface must be flat, clean, dry, and sound before installation. Dust, ridges, and old adhesive residue can prevent proper bonding or show through the finished floor.

Question 5Floor Covering Craft Fundamentals

What does the term "pile direction" refer to in carpet?

  1. The direction of traffic flow through the room
  2. The direction of the seams relative to the light source
  3. The orientation of the carpet's tufts, which affects shade and appearance Correct answer.
  4. The direction the carpet roll is unrolled in the room

Explanation

Carpet tufts lean in a consistent direction, and installing pieces with mismatched pile direction causes visible shading differences at seams. Installers keep pile direction consistent across the installation to avoid this.

Question 6Floor Covering Craft Fundamentals

Which adhesive type is typically specified for installing carpet tile?

  1. Pressure-sensitive adhesive Correct answer.
  2. Hot-melt glue sticks
  3. Contact cement
  4. Epoxy adhesive

Explanation

Carpet tile is commonly installed with pressure-sensitive adhesive that holds tiles in place while allowing later release and replacement. Contact cement and epoxy are used for other materials and are not standard for carpet tile.

Question 7Floor Covering Craft Fundamentals

What is the purpose of a seam roller in resilient sheet flooring installation?

  1. To press the seam edges together and ensure full adhesive contact Correct answer.
  2. To remove air bubbles from the field of the sheet
  3. To heat-activate seam adhesive
  4. To trim excess material at the seam

Explanation

After the seam is joined, a seam roller presses the edges to ensure the adhesive bonds fully and the seam lies flat. It does not cut, heat, or remove field bubbles.

Question 8Floor Covering Craft Fundamentals

Which personal protective equipment is most important when mixing and applying solvent-based floor adhesive in an enclosed room?

  1. Cut-resistant gloves
  2. Steel-toe boots
  3. Respiratory protection and adequate ventilation Correct answer.
  4. Hearing protection

Explanation

Solvent-based adhesives release volatile vapors that can be harmful in enclosed spaces, so respiratory protection and ventilation are essential. Other PPE may be required but does not address the primary vapor hazard.

Question 9Floor Covering Craft Fundamentals

A carpet installer is laying carpet in a room with an irregular wall line. What is the best approach to fitting the carpet at that wall?

  1. Rough-cut with extra allowance, then trim to fit after stretching Correct answer.
  2. Cut the carpet short to avoid bunching
  3. Trim exactly to the wall line before stretching
  4. Fold the excess under the baseboard

Explanation

Rough-cutting with an allowance lets the installer stretch the carpet into position first, then trim precisely along the wall. Trimming before stretching risks the carpet pulling short of the wall.

Question 10Floor Covering Craft Fundamentals

When installing resilient sheet flooring in a large room, why is it often necessary to seam two or more sheets?

  1. Seams improve the floor's flexibility
  2. Manufacturers require seams in every room
  3. Seams prevent telegraphing of substrate defects
  4. Sheet goods come in limited roll widths, so wide rooms need seams Correct answer.

Explanation

Resilient sheet goods are manufactured in standard roll widths, so rooms wider than the roll require seaming multiple pieces. Seams are a practical necessity, not a requirement or a benefit to flexibility.

Question 11Floor Covering Craft Fundamentals

What is the purpose of acclimating resilient tile to the room before installation?

  1. To allow the tile to reach room temperature and stabilize dimensions Correct answer.
  2. To remove manufacturing oils from the surface
  3. To activate the adhesive on the back of the tile
  4. To soften the tile so it bends around corners

Explanation

Resilient tile expands and contracts with temperature, so allowing it to reach room conditions prevents dimensional changes after installation that could open seams or cause buckling. Acclimation is about temperature stabilization, not softening or cleaning.

Question 12Floor Covering Craft Fundamentals

A crew is installing carpet over a wood subfloor with a slight crown. What is the appropriate corrective action?

  1. Install carpet directly; the cushion will hide the crown
  2. Install tackless strip over the crown to flatten it
  3. Sand or fill the crown to achieve a flat surface before installing cushion Correct answer.
  4. Add a second layer of cushion over the crown

Explanation

Subfloor flatness tolerances must be met before carpet and cushion are installed, because cushion does not correct a crowned floor and the defect can telegraph or cause uneven wear. Sanding or filling brings the surface within tolerance.

Question 13Floor Covering Craft Fundamentals

Which method is used to join two pieces of resilient sheet flooring with a heat-welded seam?

  1. Overlap the edges and roll them flat
  2. Apply contact cement and press the edges together
  3. Staple the edges and cover with cove base
  4. Groove the seam and weld with a hot-air gun and welding rod Correct answer.

Explanation

Heat welding requires grooving the seam, melting a welding rod into the groove with a hot-air gun, and trimming the cooled weld flush. This produces a strong, watertight seam for demanding environments.

Question 14Floor Covering Craft Fundamentals

What is the function of cove base in a resilient flooring installation?

  1. To hold tackless strip in place
  2. To provide a decorative transition between floor and wall that seals the edge Correct answer.
  3. To level the subfloor at the wall
  4. To support the weight of the flooring at the perimeter

Explanation

Cove base curves from the floor up onto the wall, covering the perimeter edge and helping seal the junction. It is a finish detail, not a structural or leveling element.

Question 15Floor Covering Craft Fundamentals

An installer notices that carpet seams are visible as a shade difference. Which cause is most likely?

  1. The cushion is too thick at the seam
  2. The two pieces were laid with opposite pile direction Correct answer.
  3. The tackless strip was installed too close to the wall
  4. The seam tape was applied too cold

Explanation

Mismatched pile direction causes adjacent pieces to reflect light differently, making the seam appear as a shade change. Keeping pile direction consistent across all pieces prevents this appearance issue.

Question 16Floor Covering Craft Fundamentals

Why should adhesive be allowed to become tacky before laying resilient tile in a pressure-sensitive system?

  1. To reduce the amount of adhesive needed
  2. To allow the solvent or water to flash off so the adhesive grips the tile Correct answer.
  3. To increase the open time indefinitely
  4. To prevent the tile from sliding during layout

Explanation

Pressure-sensitive adhesive must flash off its carrier so it develops tack; laying tile into wet adhesive can trap moisture and weaken the bond. Waiting for proper tack ensures the intended holding strength.

Question 17Floor Covering Craft Fundamentals

A room measures 4.5 m by 6 m. Resilient sheet flooring comes in a 3.66 m wide roll. What is the minimum number of seams required to cover the floor with the roll running lengthwise along the 6 m dimension?

  1. 1 Correct answer.
  2. 2
  3. 3
  4. 0

Explanation

With the roll running along the 6 m length, the 3.66 m width covers part of the 4.5 m room width, leaving 0.84 m to cover. That remaining strip requires one seam to join it to the main sheet.

Question 18Floor Covering Craft Fundamentals

What is the correct sequence for installing wall-to-wall carpet over cushion?

  1. Install carpet, stretch, then install tackless strip and cushion
  2. Install cushion, install tackless strip, trim carpet, then stretch
  3. Install tackless strip, stretch carpet, then install cushion and trim
  4. Install tackless strip, install cushion, rough-cut and seam carpet, stretch, then trim Correct answer.

Explanation

Tackless strip goes down first around the perimeter, then cushion is installed inside it, then the carpet is rough-cut, seamed, stretched onto the pins, and trimmed. Following this order ensures the stretch is effective and the edges are secure.

Question 19Floor Covering Craft Fundamentals

Which condition most directly causes telegraphing of substrate defects through resilient sheet flooring?

  1. Installing over a flat but slightly dusty slab
  2. Insufficient filling or leveling of depressions and ridges Correct answer.
  3. Acclimating the material at room temperature
  4. Using a pressure-sensitive adhesive

Explanation

Telegraphing occurs when substrate irregularities show through the finished floor, which is why ridges and depressions must be filled and leveled before installation. Dust and acclimation affect bonding and dimensions but not telegraphing.

Question 20Floor Covering Craft Fundamentals

A carpet installer is working in a room with a large floor outlet. What is the best practice for handling the carpet around the outlet?

  1. Leave the carpet short of the outlet and caulk the gap
  2. Cut a neat opening and finish the edge around the outlet plate Correct answer.
  3. Stretch the carpet over the outlet and cover it
  4. Cut a hole larger than the outlet and leave the edges raw

Explanation

Carpet should be cut to fit neatly around floor outlets and finished so the plate covers the edge, providing a clean and safe installation. Oversized holes, covering the outlet, or leaving gaps create appearance and safety problems.

Question 21Floor Covering Craft Fundamentals

Which factor most influences the choice between a hard-set and a pressure-sensitive adhesive for a resilient floor?

  1. The expected traffic and the need for future replacement Correct answer.
  2. The brand of the installation tools
  3. The room's ceiling height
  4. The color of the flooring

Explanation

Hard-set adhesives form a permanent bond suited to high traffic, while pressure-sensitive adhesives allow later release for replacement. Traffic demands and replacement needs drive the selection.

Question 22Floor Covering Craft Fundamentals

A crew is installing carpet tile in a room where the layout must hide seams along the main entry sightline. What layout strategy best achieves this?

  1. Start at the entry door and work outward
  2. Install tiles diagonally to the walls
  3. Center the layout on the main sightline and work outward symmetrically Correct answer.
  4. Begin in a corner with full tiles and allow cut tiles at the entry

Explanation

Centering the layout on the dominant sightline distributes cut tiles to the perimeter and keeps the entry view balanced. Corner starts push irregular cuts to the most visible area.

Question 23Floor Covering Craft Fundamentals

Why must the relative humidity and temperature of a concrete slab be considered together with the vapor emission rate before installing resilient flooring?

  1. Because temperature controls the slab's compressive strength
  2. Because humidity only affects adhesive color
  3. Because humidity determines the roll width of the flooring
  4. Because both influence the equilibrium moisture condition and the risk of bond failure Correct answer.

Explanation

Slab moisture equilibrium depends on both temperature and relative humidity, and elevated conditions can increase vapor drive and adhesive failure risk. Testing and documenting both gives a realistic picture of whether the slab is ready.

Question 24Floor Covering Craft Fundamentals

An installer must seam two carpet pieces in a high-traffic corridor. Which seam placement and method best reduces seam failure?

  1. Place the seam parallel to and directly in the main traffic lane, using hand-sewn edges
  2. Place the seam diagonally across the corridor
  3. Place the seam perpendicular to traffic where possible and use a proper seaming method with adequate tape or adhesive Correct answer.
  4. Place the seam along the wall line to hide it

Explanation

Seams oriented perpendicular to traffic experience less concentrated wear, and a proper seaming method with adequate tape or adhesive strengthens the joint. Placing a seam in the main traffic lane invites early failure.

Question 25Floor Covering Craft Fundamentals

A resilient sheet floor is being installed in a refrigerated space. What is the most important installation consideration?

  1. Using a standard adhesive at room temperature
  2. Selecting an adhesive and material system rated for low-temperature service and allowing proper cure Correct answer.
  3. Installing the flooring before the refrigeration is turned on regardless of adhesive
  4. Increasing the seam overlap to compensate for contraction

Explanation

Low-temperature environments require adhesives and materials rated for that service, and the adhesive must cure under suitable conditions before the space is brought to operating temperature. Standard room-temperature adhesives may not bond or cure properly.

Question 26Floor Covering Craft Fundamentals

Which tool is specifically designed for cutting and trimming resilient tile around obstructions such as pipes and door jambs?

  1. Utility knife Correct answer.
  2. Tile nipper
  3. Seam roller
  4. Carpet knee kicker

Explanation

A utility knife with a sharp blade is the standard hand tool for scoring and trimming resilient tile to fit around obstacles. It allows controlled cuts and is used in both straight and curved trimming. Other tools listed serve different purposes in floor covering.

Question 27Floor Covering Craft Fundamentals

When installing a carpet gripper (tackless strip) along a wall, what is the correct orientation of the pins?

  1. Pins pointing straight up
  2. Pins angled toward the wall
  3. Pins angled away from the wall Correct answer.
  4. Pins angled parallel to the wall

Explanation

Tackless strip must be installed with the pins angled toward the wall so that the carpet backing is hooked and held securely when stretched. This orientation prevents the carpet from releasing under tension. Installing pins in other directions reduces holding power.

Question 28Floor Covering Craft Fundamentals

What is the primary purpose of a moisture test on a concrete slab before installing resilient flooring?

  1. To ensure the slab's moisture emission is within the flooring manufacturer's limits Correct answer.
  2. To measure the slab's pH level
  3. To determine the slab's compressive strength
  4. To check for the presence of curing compounds

Explanation

Moisture testing determines whether the concrete slab emits excess moisture vapor that could damage adhesives or flooring. Manufacturers specify maximum allowable moisture emission rates, and exceeding them can cause bond failure or flooring deterioration. Other tests assess different properties.

Question 29Floor Covering Craft Fundamentals

Which type of underlayment is commonly used under resilient flooring to provide a smooth, uniform surface?

  1. Hardboard Correct answer.
  2. Plywood
  3. Oriented strand board (OSB)
  4. Particleboard

Explanation

Hardboard underlayment is dense, smooth, and resistant to indentation, making it suitable for resilient flooring. Plywood and OSB may have surface irregularities or grain patterns that telegraph through. Particleboard is susceptible to moisture damage and swelling.

Question 30Floor Covering Craft Fundamentals

A flooring installer is preparing a concrete subfloor that has a high spot. What is the appropriate action to ensure a flat surface for resilient flooring?

  1. Grind down the high spot Correct answer.
  2. Install the flooring directly over the high spot
  3. Cover the high spot with a layer of underlayment
  4. Fill the high spot with patching compound

Explanation

High spots must be removed by grinding to achieve a flat plane; filling low spots with patching compound is done separately. Installing over a high spot can cause rocking, telegraphing, or premature wear. Underlayment does not correct an uneven substrate.

Question 31Floor Covering Craft Fundamentals

When installing carpet over a wood subfloor, why is it important to use a cushion with the correct density and thickness?

  1. To reduce the cost of the installation
  2. To make the carpet easier to stretch
  3. To increase the height of the floor
  4. To provide sufficient support and extend the carpet's life Correct answer.

Explanation

Cushion density and thickness affect support and resilience; too soft or too thick a cushion can cause carpet to mat or wrinkle. The correct cushion helps distribute loads and extends carpet life. Cost, stretchability, and height are secondary considerations.

Question 32Floor Covering Craft Fundamentals

What is the recommended method for joining two pieces of carpet when a seam is necessary?

  1. Glue the edges with construction adhesive
  2. Tape the edges with duct tape
  3. Overlap the edges and cut through both layers Correct answer.
  4. Butt the edges together and sew them

Explanation

The standard method for a carpet seam is to overlap the two pieces, then cut through both layers with a sharp knife guided by a straightedge, creating perfectly matched edges. The edges are then joined with seam tape and sealer. Sewing, gluing, or taping are not standard practices.

Question 33Floor Covering Craft Fundamentals

Which factor most affects the open time of a flooring adhesive?

  1. The age of the adhesive container
  2. The type of trowel used
  3. The color of the adhesive
  4. The ambient temperature and humidity Correct answer.

Explanation

Open time, the period during which adhesive remains workable, is significantly influenced by temperature and humidity. Higher temperatures and low humidity can shorten open time, while cooler, more humid conditions may extend it. Color, trowel type, and container age are less directly influential.

Question 34Floor Covering Craft Fundamentals

A resilient sheet flooring installation requires a seam along a wall. Which technique is best for creating a tight seam?

  1. Leave a gap and fill with patching compound
  2. Overlap the sheets and nail them together
  3. Overlap the sheets, then cut through both with a straightedge and knife Correct answer.
  4. Butt the sheets and apply seam sealer without cutting

Explanation

For a tight seam in resilient sheet flooring, the standard technique is to overlap the sheets, then cut through both layers with a straightedge and knife, creating perfectly matched edges. The cut edges are then joined with seam sealer or welded. Butting without cutting may not produce a precise fit.

Question 35Floor Covering Craft Fundamentals

When installing carpet on stairs, what is the correct procedure for securing the carpet at the nose of each tread?

  1. Glue the carpet to the tread only
  2. Stretch the carpet tightly over the nose without fasteners
  3. Staple the carpet to the riser only
  4. Use a stair tool to force the carpet into the crotch and secure with staples Correct answer.

Explanation

Proper stair carpet installation involves using a stair tool to push the carpet tightly into the crotch (the junction of tread and riser) and securing it with staples or tacks. This prevents the carpet from pulling loose and ensures a safe, durable installation. Other methods do not provide adequate security.

Question 36Floor Covering Craft Fundamentals

What is the purpose of a carpet power stretcher in wall-to-wall carpet installation?

  1. To install tackless strip
  2. To remove wrinkles and ensure a tight fit Correct answer.
  3. To seam two pieces of carpet
  4. To cut carpet to size

Explanation

A power stretcher is used to stretch carpet tightly from wall to wall, eliminating wrinkles and ensuring a proper fit. It engages the carpet and stretches it over the tackless strip. Cutting, seaming, and installing tackless strip are done with other tools.

Question 37Floor Covering Craft Fundamentals

Which of the following is a key step in preparing a wood subfloor for a resilient flooring installation?

  1. Sanding the surface to remove imperfections Correct answer.
  2. Applying a moisture barrier
  3. Installing a wire mesh reinforcement
  4. Sealing the wood with polyurethane

Explanation

Wood subfloors must be clean, flat, and free of defects; sanding removes high spots, paint, and other imperfections. Moisture barriers are typically for concrete, polyurethane sealing is not standard, and wire mesh is for concrete reinforcement.

Question 38Floor Covering Craft Fundamentals

A crew is installing carpet tile in a commercial space and needs to determine the layout to minimize waste and maintain pattern alignment. Which principle is most important?

  1. Install tiles in a random pattern to hide seams
  2. Align tiles with the longest wall
  3. Start from the center of the room and work outward Correct answer.
  4. Start from the main entrance and work inward

Explanation

For carpet tile, starting from the center and working outward helps maintain symmetry and pattern alignment, and minimizes waste at edges. Starting from an entrance or aligning with a wall can lead to unbalanced borders. Random patterns are not typical for carpet tile.

Question 39Floor Covering Craft Fundamentals

When installing resilient sheet flooring over a concrete slab with a high moisture emission rate, what is the most appropriate action?

  1. Use a thicker flooring material
  2. Install a moisture barrier coating or use a moisture-resistant adhesive Correct answer.
  3. Increase the amount of adhesive applied
  4. Install the flooring without any special precautions

Explanation

High moisture emission can cause adhesive failure and flooring damage; applying a moisture barrier coating or using a moisture-resistant adhesive system is the correct mitigation. Increasing adhesive or using thicker flooring does not address the moisture problem and may worsen it.

Question 40Floor Covering Craft Fundamentals

In a large commercial installation, why is it important to use a seam sealer or welding rod on resilient sheet flooring seams?

  1. To prevent moisture and dirt from penetrating the seam Correct answer.
  2. To improve the appearance of the seam
  3. To allow for expansion and contraction
  4. To make the seam easier to clean

Explanation

Seam sealer or welding rod fills the seam gap, preventing moisture, dirt, and bacteria from entering, which protects the adhesive and flooring. While a sealed seam may be easier to clean and look better, the primary purpose is protection. Expansion and contraction are accommodated by other means.

Question 41Safety and Jobsite Practices

Before spreading adhesive in a room being floor-covered, the crew notices the general contractor's electrical rough-in is still open in the slab. What is the most appropriate action?

  1. Fill the opening with floor patch and continue installing
  2. Stop work in that area and coordinate with the GC to close the penetration Correct answer.
  3. Cover the opening with underlayment and proceed
  4. Spread adhesive only in the far half of the room and return later

Explanation

An open penetration is another trade's incomplete work and a fall and trip hazard; floor covering crews must not cover or alter it. The correct practice is to stop in that area and coordinate through the GC so the opening is closed before flooring proceeds. Covering it hides a hazard and can void warranties or inspection approvals.

Question 42Safety and Jobsite Practices

Which personal protective equipment is required when using a knee kicker to stretch carpet in a finished commercial corridor?

  1. Welding goggles and leather sleeves
  2. Face shield and rubber apron
  3. Respirator and hearing muffs
  4. Safety glasses and knee pads Correct answer.

Explanation

Carpet stretching with a knee kicker exposes the eyes to flying staples and debris and loads the knees heavily, so safety glasses and knee pads are the standard protection. Face shields, welding gear, and respirators address hazards not created by normal knee-kicker operation.

Question 43Safety and Jobsite Practices

A crew must cut vinyl tile in a small, poorly ventilated room. Which control practice best protects workers from adhesive and dust exposure?

  1. Run fans to exhaust air outdoors and wear the specified respirator Correct answer.
  2. Close the door to keep dust out of the corridor
  3. Open a window and skip respiratory protection
  4. Work faster so exposure time is shorter

Explanation

Ventilation that exhausts contaminated air outdoors, combined with the respirator named on the SDS, controls inhalation exposure. Confining dust to the room, speeding up, or relying on a single open window does not reliably reduce exposure below limits.

Question 44Safety and Jobsite Practices

What is the first thing a floor covering installer should do when arriving at a jobsite?

  1. Move materials into the work area
  2. Check in and complete required site orientation and sign-in Correct answer.
  3. Begin laying out the pattern
  4. Start removing old flooring

Explanation

Site access and orientation come first, because the general contractor must account for everyone on site and brief them on hazards and emergency procedures. Starting layout, staging, or demolition before check-in skips required safety and access controls.

Question 45Safety and Jobsite Practices

Which condition most commonly indicates that a concrete slab is not ready to receive a moisture-sensitive floor covering?

  1. The slab has a light broom finish
  2. The slab shows visible dampness or high moisture readings Correct answer.
  3. The slab was poured more than 28 days ago
  4. The slab surface is slightly dusty

Explanation

Visible dampness or elevated moisture readings signal that the slab has not dried enough, and installing over it can trap moisture and cause adhesive failure. Age, surface dust, and broom finish are separate concerns that do not by themselves indicate excess moisture.

Question 46Safety and Jobsite Practices

A floor covering crew is working near an active overhead operation. What is the appropriate jobsite practice?

  1. Wear a hard hat and stay clear of the overhead work zone Correct answer.
  2. Rely on the operator to watch for the crew
  3. Work directly under the operation to save time
  4. Ask the operator to stop work until the crew finishes

Explanation

Overhead work creates struck-by and dropped-object hazards, so workers wear head protection and keep out of the fall zone. Working under the operation or depending on the operator to watch for you does not remove the hazard.

Question 47Safety and Jobsite Practices

When should a floor covering installer read the Safety Data Sheet for an adhesive?

  1. Before using the product for the first time Correct answer.
  2. Only after a spill occurs
  3. After the job is completed
  4. Only when the inspector requests it

Explanation

The SDS must be reviewed before first use so the worker knows the hazards, required PPE, and first-aid and spill procedures. Reading it only after a spill, on request, or after the job defeats its purpose as a preventive tool.

Question 48Safety and Jobsite Practices

What is the main reason for keeping the work area clear of scrap carpet and backing materials throughout the shift?

  1. To make the finished floor look cleaner
  2. To speed up the final walk-through
  3. To avoid paying disposal fees
  4. To reduce trip and fall hazards and keep exits clear Correct answer.

Explanation

Loose scrap and backing create slip, trip, and fall hazards and can block egress paths, which must stay clear. Appearance, walk-through speed, and disposal costs are secondary and not the safety reason for continuous housekeeping.

Question 49Safety and Jobsite Practices

An installer is about to use a solvent-based adhesive in a room where a pilot light is burning. What should the installer do?

  1. Proceed if the room feels cool
  2. Ventilate the room and eliminate the ignition source before using the adhesive Correct answer.
  3. Use the adhesive quickly before vapors build up
  4. Place a fan near the pilot light to blow vapors away

Explanation

Solvent vapors can travel and ignite at a remote ignition source, so the source must be shut off and the space ventilated before adhesive is opened. Temperature, speed, or a fan aimed at the flame does not remove the ignition hazard.

Question 50Safety and Jobsite Practices

Which practice correctly protects a floor covering crew when removing old resilient flooring that may contain asbestos?

  1. Use a standard shop vacuum to collect dust
  2. Wet the material and use a vacuum with a HEPA filter Correct answer.
  3. Break the material into small pieces for faster hauling
  4. Dry-sweep the debris into a pile

Explanation

Wetting the material keeps fibers from becoming airborne, and HEPA filtration captures fine particles that a standard vacuum would release. Breaking, dry-sweeping, or using an ordinary shop vacuum disperses fibers into the breathing zone.
