CSLB C-17 Glazing (Trade Exam) — All Questions

A door of 12 square feet has 3 square feet of glass. How does the Energy Code treat it?

• a.An opaque door, since glass is only a small share
• b.Exempt from the glazing rules in the code
• c.A skylight, since it is in an exterior wall
• d.Fenestration, since glass is 25 percent of the door✓

3 ÷ 12 is exactly 25 percent, and glass area greater than or equal to 25 percent makes the door a fenestration product. An opaque door has under 25 percent, and the door is not a skylight or exempt.2025 Energy Code residential compliance manual, Ch. 3

A door of 24 square feet has 2 square feet of glass. How is it treated?

• a.As a window
• b.As an opaque exterior door✓
• c.As a fenestration product
• d.As a glazed door needing NFRC glass values

2 ÷ 24 is 8.3 percent, which is under 25 percent, so the door is treated as opaque. It is not fenestration, does not need glass values and is not a window.2025 Energy Code residential compliance manual, Ch. 3

A new window is not field-fabricated. What label must it carry?

• a.A tint label stating the color of the glass tint
• b.A wind rating label that gives the design pressure
• c.An NFRC-certified or default-efficiency label✓
• d.An installer sticker that gives the crew's name

Windows that are not field-fabricated must be labeled with NFRC-certified or default efficiencies. A tint, installer or wind rating label does not state U-factor and SHGC.2025 Energy Code residential compliance manual, Ch. 3

Where do field-fabricated windows get their U-factor and SHGC for compliance?

• a.From the previous window
• b.From the installer's estimate
• c.From the glass supplier's brochure
• d.From the Energy Code default tables✓

Field-fabricated windows use the default tables of the Energy Code. A brochure, an estimate or the old window's value is not an accepted source.2025 Energy Code residential compliance manual, Ch. 3

Which label is applied for the building inspector's review of default values?

• a.A temporary label✓
• b.A sales invoice
• c.A permanent engraving
• d.An insurance certificate

Temporary labels carrying the compliance values are applied for the inspector. A permanent engraving, an insurance certificate and an invoice are not the review label.2025 Energy Code residential compliance manual, Ch. 3

Why must the glass manufacturer be consulted before adding film to an annealed lite?

• a.Film moves the setting blocks out of position
• b.Film makes the frame heavier on the wall
• c.Film changes solar absorption and thermal stress✓
• d.Film makes the glass thinner in the frame

Film changes how the lite absorbs solar energy, and annealed glass can break from thermal stress. The frame weight added by film is negligible, film does not thin the glass, and it does not move the setting blocks.CEC manual (window film); Pilkington ATS-192

What benefit does laminated glass add in a retrofit besides safety glazing performance?

• a.Elimination of the need for a frame
• b.Lower weight than annealed glass
• c.Greater optical distortion removal
• d.Reduced sound transmission✓

The industry paper lists reduced sound transmission as a benefit of laminated glass. It does not remove distortion, eliminate the frame or weigh less than annealed glass of the same thickness.GANA FB45-14 Recommended Applications for Heat-Treated Glass (2019)

In a dwelling, an operable window has its clear opening 18 inches above the floor and 40 feet above grade. What does the Residential Code require?

• a.A larger sash so the window can open wider
• b.A screen fixed over the full window opening
• c.A 4-inch sphere limit or a control device✓
• d.A guard placed in front of the glass only

Windows with a sill under 24 inches above the floor and more than 72 inches above grade must stop a 4-inch sphere or have a window opening control device. A guard in front of the glass is not the listed solution, a larger sash opens wider and makes the fall hazard worse, and a screen does not stop a child from falling through.2025 CRC §R321.2.1

A window opening control device is installed on an emergency escape window. What must hold after the device is released?

• a.The window must be fixed in place so it cannot open
• b.The device must hold the sash half open at all times
• c.The device must stay locked until it is reset with a key
• d.The net clear opening must still meet the required area✓

After release the device must not reduce the net clear opening area of the unit below the area required for escape. A sash held half open, a device that stays locked until a key resets it, and a sash fixed in place each defeat escape.2025 CRC §R321.2.2

What is the maximum prescriptive fenestration U-factor for climate zone 3 in the Energy Commission's manual?

• a.0.40
• b.0.10
• c.0.27✓
• d.0.50

The manual gives 0.27 for climate zones 1 through 5, 11 through 14 and 16, and 0.30 for the others. The 0.40 figure is the mandatory area-weighted limit, and 0.50 and 0.10 are not stated.2025 Energy Code residential compliance manual, Ch. 3

A retrofit replaces single glass with a thicker insulating unit. What must be checked about the existing frame?

• a.Pocket depth and the frame's capacity for the added weight✓
• b.The brand of the sealant that was used on the old glass
• c.The color of the frame and the glazing stops
• d.Nothing, since every pocket accepts every unit

A thicker unit needs a deeper pocket and the frame carries more weight, so both are checked. Color and sealant brand do not decide fit, and pockets are not universal.Pilkington ATS-192; Viracon Glazing Guidelines; 2025 CBC §2404.2

What does Title 8 require every employer to establish, implement and maintain?

• a.A running inventory of all job glass
• b.A written policy for bidding glass work
• c.A yearly safety banquet held for crew members
• d.An effective Injury and Illness Prevention Program✓

Section 1509 requires an effective Injury and Illness Prevention Program. A bidding policy, a yearly banquet and a glass inventory may be good business, but none is the required program.Title 8 §1509(a)

Where must the Code of Safe Practices be available on a construction project?

• a.Kept in the owner's files at the home office only
• b.Posted at the company shop but not on the job
• c.Posted at the job site office or with each supervisor✓
• d.Mailed to each crew member once every year

The Code is posted at each job site office or provided to each supervisory employee. Owner-only files, an annual mailing and shop-only posting never reach the crew on the job.Title 8 §1509(c)

Supervisors conduct tailgate safety meetings with crews at least how often?

• a.Every 3 working days
• b.Every 90 working days
• c.Every 10 calendar months
• d.Every 10 working days✓

Section 1509 sets the interval at every 10 working days. Ten months and 90 days are far too long, and every 3 days is more often than required.Title 8 §1509(e)

What must workers receive when first employed?

• a.Hazard instruction, and direction to read the Code✓
• b.Hazard instruction at the first Cal/OSHA inspection
• c.A tool allowance and a written test on the codes
• d.A copy of the license and the project drawings

Section 1510 requires instruction on hazards and precautions for the work and direction to read the Code of Safe Practices. A tool allowance and test are not required, instruction cannot wait for an inspector to arrive, and a license copy and drawings are not part of the first-day requirement.Title 8 §1510(a)

Workers are subject to known hazards such as flammable liquids and toxic materials. What instruction is required?

• a.A verbal warning only, given once at the start of the shift
• b.Nothing, if the workers say they are experienced
• c.A brochure left in the truck for any who want it
• d.Hazard recognition, self-protection procedures and first aid✓

Employees exposed to known job site hazards are instructed in recognizing the hazard, protecting themselves and first aid. A spoken warning, a brochure and an experience-based exemption do not meet that duty.Title 8 §1510(c)

What must each employer ensure about first aid on a construction site?

• a.A first-aid arrangement that is made by calling the owner
• b.A first-aid course taken once every ten years
• c.A suitable number of appropriately trained first-aid persons✓
• d.A trained person only if ten or more are working

Section 1512 requires a suitable number of appropriately trained persons. A headcount threshold, a decade-old class and calling the owner do not satisfy it.Title 8 §1512(b)

How is the required first-aid kit kept on a construction project?

• a.In a locked office, with no key kept on site
• b.In an open box carried loose in the truck bed
• c.Weatherproof, with used items promptly replaced✓
• d.Stocked once at the start and never checked

The kit goes in a weatherproof container and is inspected so expended items are promptly replaced. An open box is not weatherproof, a locked office with no key on site is inaccessible in an emergency, and one-time stocking leaves used items unreplaced.Title 8 §1512(c)

Who must see that required personal protective equipment is used?

• a.The employer✓
• b.Only the employee
• c.Only the supplier
• d.Only the owner

The employer requires employees to use the required PPE. The employee alone, the supplier and the owner do not carry that duty under the section.Title 8 §1514(a)

What does Title 8 say about how PPE is selected for the hazards?

• a.By the color the crew prefers to wear
• b.By the product the supplier recommends
• c.By the hazards identified in a hazard assessment✓
• d.By the lowest price per unit available

Section 3380 requires selecting PPE that protects from the hazards identified in the hazard assessment. Price, the crew's color preference and a supplier's recommendation are not criteria.Title 8 §3380(f)

Which hazard calls for eye protection under Title 8?

• a.Cold weather and frost on the work
• b.Low light inside an unfinished building
• c.Loud noise from a nearby power saw
• d.Flying particles that could injure the eye✓

Section 3382 covers risk of eye injuries such as punctures, abrasions, contusions or burns from flying particles and similar hazards. Cold, low light and noise are not eye hazards under it; noise calls for hearing protection.Title 8 §3382

Where are gloves not worn according to Title 8?

• a.Anywhere on a job site that happens to be outdoors
• b.Where they could be pulled into moving machinery✓
• c.Within five feet of an extension ladder
• d.Wherever sheet glass is being carried by hand

Gloves are not worn where there is a danger of entanglement in moving machinery. Carrying glass is a reason to wear them, and outdoor or ladder locations are not exclusions.Title 8 §3384(b)

Foot protection is required for exposure to which hazard?

• a.Quiet interior work in a finished lobby
• b.Bright sunlight falling on an exterior storefront
• c.Falling objects and crushing or penetrating actions✓
• d.Light foot traffic along a hallway

Section 3385 requires foot protection for hazards including falling objects and crushing or penetrating actions. Sunlight, quiet work and light traffic are not foot hazards.Title 8 §3385

When is body protection required?

• a.Only for supervisors who walk the job site
• b.When work exposes employees to injurious materials✓
• c.Only during the cold winter months of the year
• d.Only during the first week on a project

Appropriate body protection is required for employees whose work exposes them to injurious materials. Season, rank and the first week of a job are not the test.Title 8 §1522

What must an employer provide employees about hazardous chemicals such as primers and cleaners?

• a.Labels only, with no data sheets or training
• b.A verbal tip from the crew leader when asked
• c.Safety data sheets, but only after an injury occurs
• d.A hazard communication program, with training✓

Section 5194 requires information through a hazard communication program, with labels and other warnings, safety data sheets and training. A verbal tip on request is not a program, data sheets must be available before exposure and not after an injury, and labels alone leave out the data sheets and training the standard also requires.Title 8 §5194

What does the glass manufacturer say about thinning glazing compounds?

• a.Thin them with toluene for easier tooling
• b.Thin them with dry-cleaning fluid when cold
• c.Do not thin them with chlorinated solvents✓
• d.Thin them with any solvent on the truck

Glazing compounds must not be thinned with chlorinated solvents, which include dry-cleaning fluids, or with benzene-related compounds such as toluene. Any solvent is therefore wrong.Pilkington ATS-192 General glazing guidelines (2013)

What does Title 8 have for drilling into concrete or masonry that creates silica dust?

• a.A standard on respirable crystalline silica exposure✓
• b.A rule that covers office buildings only
• c.A rule that covers plumbing contractors only
• d.A rule that covers demolition work only

Title 8 has a standard on respirable crystalline silica that employers must follow when exposure can occur. It is not limited to demolition, to office buildings, or to one trade.Title 8 §5204

What drinking water must employees have in outdoor work?

• a.Potable water that is fresh, pure and suitably cool✓
• b.Warm water kept in an uncovered open tank
• c.Water the employees bring from home each day
• d.Soft drinks that are sold to the whole crew at cost

The heat standard requires access to potable drinking water that is fresh, pure, suitably cool and provided free of charge, as close as practicable to the work. Water that employees bring from home leaves the supply to them, warm water in an uncovered tank is neither cool nor pure, and soft drinks sold at cost are not free potable water.Title 8 §3395(c)

At what outdoor temperature must shade be present for employees?

• a.Above 100 degrees Fahrenheit
• b.Above 60 degrees Fahrenheit
• c.Above 80 degrees Fahrenheit✓
• d.Above 120 degrees Fahrenheit

Shade must be present when the temperature exceeds 80 degrees. Sixty is lower than the trigger, and 100 and 120 are higher than the trigger.Title 8 §3395(d)

At 96 degrees Fahrenheit, what does the heat standard require in the high-heat procedures?

• a.A ten-minute rest every two hours✓
• b.A thirty-minute rest taken every two hours
• c.No rest, since breaks stay optional at 96 degrees
• d.A single rest taken once during the shift

At 95 degrees or above, employees take a minimum ten-minute net cool-down rest period every two hours. Optional breaks do not meet the high-heat procedures, a thirty-minute rest overstates the minimum, and one rest per shift is too infrequent.Title 8 §3395(e)

What form must an employer's heat illness prevention plan take?

• a.A written plan that covers farm work only
• b.A written plan, in English and the crew's language✓
• c.A written plan in English only, kept at the office
• d.A spoken plan that is explained at hiring

The employer maintains an effective written plan in English and in the language understood by the majority of employees. A spoken plan is not written, an English-only plan leaves out the crew's language, and a plan limited to agriculture does not cover a construction crew working outdoors.Title 8 §3395(i)

Can a body harness be used to hoist glass?

• a.No, harnesses are for employee protection only✓
• b.Yes, when the lifeline is wire rope
• c.Yes, when a second lanyard is attached
• d.Yes, if the lite weighs well under 50 pounds

Body belts, harnesses and components are used only for employee protection and not to hoist materials. A light weight does not change that, a second lanyard does not turn a harness into a hoisting device, and a wire-rope lifeline is still a fall-protection line.Title 8 §1670(b)(13)

At what height of fall exposure at an unprotected edge is a personal fall arrest, restraint or positioning system required?

• a.In excess of 4-1/2 feet
• b.In excess of 15 feet
• c.In excess of 7-1/2 feet✓
• d.In excess of 10 feet

Section 1670 sets the threshold at falling in excess of 7-1/2 feet from the perimeter of a structure or unprotected sides and edges. Four and a half, ten and fifteen feet are not the threshold.Title 8 §1670(a)

What must the anchorage for a personal fall arrest system support per employee attached?

• a.At least 500 pounds
• b.At least 5,000 pounds✓
• c.At least 50 pounds
• d.At least 1,000 pounds

The anchorage supports at least 5,000 pounds per employee, or is part of a system with a safety factor of two under qualified supervision. The other figures are too low.Title 8 §1670(b)(10)

What is the maximum arresting force on a person wearing a harness in a fall arrest?

• a.3,000 pounds
• b.1,800 pounds✓
• c.900 pounds
• d.5,000 pounds

A system limits maximum arresting force to 1,800 pounds with a body harness. The 5,000 pounds is a strength requirement, 900 pounds applies to belts in restraint and positioning, and 3,000 pounds is a tensile load for short-fall retractables.Title 8 §1670(b)(11)

What is the greatest free fall a fall arrest system is rigged to allow?

• a.15 feet
• b.12 feet
• c.2 feet
• d.6 feet✓

The system is rigged so an employee cannot free fall more than 6 feet. Twelve and 15 feet exceed it, and 2 feet is the limit for positioning devices.Title 8 §1670(b)(11)

What must an employer do before employees begin work at a site?

• a.Order the glass and schedule the first delivery
• b.Hire a private inspector to sign the plans
• c.Survey the site for predictable hazards and safeguards✓
• d.Set the date for the final cleaning of the glass

Section 1511 requires a thorough survey of site conditions to find predictable hazards and the safeguards needed before employees are present. Ordering glass, hiring an inspector and scheduling cleaning are not the survey.Title 8 §1511(b)

What does Title 8 require about debris in work areas and stairs?

• a.It is moved to the stairs
• b.It is kept reasonably cleared✓
• c.It is left for the next trade
• d.It may accumulate until the end of the job

Debris and scrap are kept reasonably cleared from work areas, passageways and stairs. Letting it accumulate until the end of the job leaves tripping hazards in the meantime, moving it to the stairs blocks the stairs, and leaving it for the next trade passes the hazard along.Title 8 §1513(a)

How are material storage areas and walkways kept?

• a.Kept as narrow as the work allows, to save space
• b.Cleared of everything, including warning signs
• c.Cleared of snow and ice, but not of debris
• d.Reasonably free of dangerous obstructions and debris✓

Section 1513 requires them reasonably free of dangerous depressions, obstructions and debris. Removing warning signs is not part of it, clearing snow and ice while leaving debris keeps only half the duty, and narrowing a walkway to save space makes obstruction more likely.Title 8 §1513(c)

Where are flammable or hazardous wastes placed?

• a.In covered containers kept apart from normal debris✓
• b.On the floor near the work for later pickup
• c.In the same dumpster that holds the packing waste
• d.Down a chute to the ground floor

Flammable or hazardous wastes go in covered containers separate from the normal debris. The dumpster, the floor and a chute do not satisfy it.Title 8 §1513(e)

What does Title 8 require to protect employees from walking through glass?

• a.No measure, because clear glass is plainly visible
• b.A removable sticker that peels off in a day
• c.A verbal warning given at the tailgate meeting
• d.Barriers or conspicuous durable markings✓

Employees are protected by barriers or by conspicuous durable markings. A verbal warning and an impermanent sticker are not durable, and clear glass is exactly the hazard.Title 8 §1525

How must floor, roof and skylight openings be guarded?

• a.By relying on careful workers to see the opening unaided
• b.By a verbal instruction to stay clear of the opening
• c.By a single strip of caution tape across it
• d.By temporary railings with toeboards, or by covers✓

Section 1632 requires temporary railings and toeboards or covers. Tape, an instruction and carefulness do not guard an opening.Title 8 §1632(b)

Workers and material imposing 180 pounds on one square foot will rest on an opening cover. What is the minimum load the cover must support?

• a.540 pounds
• b.180 pounds
• c.360 pounds
• d.400 pounds✓

The rule is the greater of 400 pounds or twice the weight imposed, and 2 × 180 = 360 is less than 400, so 400 controls. The 180 is the load itself, 360 is twice the load, and 540 triples it.Title 8 §1632(b)(3)

What must be stenciled or painted on a floor-opening cover?

• a.The date on which the cover was installed
• b.A sketch showing the size and depth of the opening
• c."Opening--Do Not Remove" in letters one inch high✓
• d.The name of the supplier of the glass and the cover

The cover bears a sign reading "Opening--Do Not Remove" with letters at least one inch high. A date, a supplier name or a sketch is not the required sign.Title 8 §1632(b)(3)

A wall opening has a 12-foot drop and its bottom edge is 30 inches above the working surface. What does Title 8 require?

• a.Nothing, since the bottom is above 24 inches
• b.A sign only
• c.The opening is guarded✓
• d.A verbal warning

A wall opening with a drop of more than 4 feet and a bottom less than 3 feet above the working surface is guarded, and 30 inches is under 36. A sign or warning alone is not a guard.Title 8 §1632(j)

A top rail must be what height above the floor?

• a.30 to 36 inches
• b.42 to 45 inches✓
• c.36 to 42 inches
• d.45 to 60 inches

The top rail is not less than 42 and not more than 45 inches above the walking level. The lower ranges are too low, and 45 to 60 inches goes above the limit.Title 8 §1620(a)(1)

A top rail is 45 inches high and no wall of 21 inches or more is present. Where is the mid-rail?

• a.Six inches above the floor level
• b.At the same height as the top rail
• c.It is not required to have one on that rail
• d.Halfway between top rail and floor✓

A mid-rail is halfway between the top rail and the floor, here 22.5 inches, when there is no wall or parapet at least 21 inches high. A mid-rail at the top-rail height is not a mid-rail, one at 6 inches is at toeboard height, and omitting it does not comply.Title 8 §1620(a)(2)

What force must a railing withstand on its top rail?

• a.At least 100 pounds, in a downward direction
• b.At least 200 pounds, outward or downward✓
• c.At least 20 pounds, either outward or downward
• d.At least 2,000 pounds, outward or downward

Railings withstand at least 200 pounds applied to the top rail within 2 inches of the top edge, outward or downward. Twenty and 100 pounds are too low, 100 pounds downward only ignores the outward load, and 2,000 is not required.Title 8 §1620(c)

How far above the upper landing must the side rails of a portable ladder extend?

• a.About 12 inches
• b.About 6 inches above the landing
• c.About 72 inches
• d.Not less than 36 inches✓

Rails extend not less than 36 inches above the landing, or the ladder is secured at the top. Six and 12 inches are too short, and 72 inches is not required.Title 8 §3276

A non-self-supporting ladder has a working length of 20 feet. Where is the foot set from the support, where possible?

• a.10 feet from the support
• b.20 feet from the support
• c.5 feet from the support✓
• d.2 feet from the support

The foot is one-quarter of the working length from the support, 20 ÷ 4 = 5 feet. Ten feet is half, 2 feet is a tenth, and 20 feet is the working length.Title 8 §3276
