Where does the building code's accessibility chapter allow the release of a pool gate's self-latching device to be mounted at most?
- a.72 inches above the ground, if it is a key lock
- b.54 inches above the ground, if not also self-locking✓
- c.24 inches above the ground, if it has a pull ring
- d.36 inches above the ground, if it has a thumb latch
The exception allows the release at 54 inches maximum above the finish floor or ground provided the device is not also self-locking and operated by a key, electronic opener or integral combination lock. The other heights are not stated.2025 CBC 11B-404.2.7, Exception 2
A pool barrier is 6 feet high, so a building permit is not needed for the fence itself. Is that correct?
- a.Yes, because a pool barrier is a landscape feature
- b.No, when the pool barrier is made of metal
- c.Yes, because the fence is under 7 feet in height
- d.No, since the 7-foot exemption excludes pool barriers✓
The permit exemption reads "other than swimming pool barriers," so a pool barrier is not exempt at any height. Metal or landscape status does not change that.2025 CBC 105.2
A playground handbook says an opening may present an entrapment hazard if the distance between interior opposing surfaces falls in what range?
- a.Less than 3.5 inches between the surfaces
- b.More than 9 inches but less than 12 inches
- c.More than 3.5 inches and less than 9 inches✓
- d.More than 12 inches between the surfaces
The handbook's range is greater than 3.5 inches and less than 9 inches. Wider and narrower openings fall outside the range.CPSC Public Playground Safety Handbook, 3.3.1
A stationary play structure is 10 feet by 6 feet. With a 6-foot use zone in all directions, what area must be surfaced?
- a.16 by 12 feet, or 192 square feet
- b.10 by 6 feet, or 60 square feet
- c.28 by 24 feet, or 672 square feet
- d.22 by 18 feet, or 396 square feet✓
The use zone adds 6 feet on every side, so (10 + 12) by (6 + 12) = 22 by 18 feet, or 396 square feet. Sixteen by twelve adds 6 feet only to one side of each dimension, 10 by 6 is the structure alone, and 28 by 24 adds 9 feet per side.CPSC Public Playground Safety Handbook, use zone
The handbook says never to use less than what depth of loose-fill surfacing, except for shredded/recycled rubber?
- a.18 inches
- b.9 inches✓
- c.3 inches
- d.12 inches
The handbook says never to use less than 9 inches of loose-fill material except for shredded or recycled rubber, where 6 inches is recommended. Three inches is far too shallow, and 12 and 18 inches are more than the minimum.CPSC Public Playground Safety Handbook, 2.2.2
What should a surfacing's critical height rating be compared with?
- a.The fall height of the highest piece of equipment✓
- b.The width of the use zone around the equipment
- c.The depth of the footings for the equipment
- d.The age of the youngest child who will use it
The rating should be greater than or equal to the fall height of the highest piece of equipment on the playground, tested to ASTM F1292. Use zone width, age and footing depth are not what it is compared with.CPSC Public Playground Safety Handbook, 2.2
Which of these is listed in the handbook as equipment not recommended for public playgrounds?
- a.Spring rockers
- b.Slides with exit zones
- c.Swinging gates✓
- d.Balance beams
The handbook lists trampolines, swinging gates, giant strides and climbing ropes not secured at both ends among equipment not recommended for public playgrounds. Slides, rockers and balance beams are standard playground equipment.CPSC Public Playground Safety Handbook, 2.3.1
Which standard guides tennis court perimeter enclosures, as listed by ASTM?
- a.ASTM F3684✓
- b.ASTM F1346
- c.ASTM F2286
- d.ASTM F2200
F3684 is the guide for tennis court fencing and other perimeter enclosures. F2286 is removable mesh pool fencing, F1346 is pool covers, and F2200 is automated vehicular gates.ASTM F3684 scope (store abstract)
What heights did the withdrawn ASTM practice for chain-link tennis court fence cover?
- a.20 or 24 feet
- b.10 or 12 feet✓
- c.14 or 16 feet
- d.4 or 6 feet
The practice was for 10- or 12-foot-high chain-link enclosures and backstops, and not for fencing higher than 12 feet. Four and six feet are residential heights, and 14 feet and more are above its limit.ASTM F969 scope (store abstract, withdrawn 2025)
According to ASTM F3684, what is the primary function of a tennis court perimeter enclosure?
- a.To support the lighting for night play
- b.To keep tennis balls in and uninvited traffic out✓
- c.To provide shade and shelter for spectators
- d.To hold the net posts at the right height
The guide states the primary function is to keep tennis balls in and uninvited traffic out, with secondary functions such as viewing and screening wind. Shade, lighting and net support are not the primary function.ASTM F3684 scope (store abstract)

Under the playground handbook, what should happen to an area with an obvious nearby hazard such as a road?
- a.Contain the children, as with a see-through fence✓
- b.Leave it open for faster evacuation of the children
- c.Surface it with loose fill and take no other measure
- d.Add a swing set along the road to keep them busy
The handbook recommends providing a method to contain children within the playground, such as a dense hedge or a fence that allows observation by supervisors. Leaving the area open invites children toward the hazard, surfacing alone does not contain them, and adding a swing set by the road adds a draw toward the hazard.CPSC Public Playground Safety Handbook, site selection
A pool fence has a 2-1/2-inch gap between the ground and the bottom rail. Does it meet Section 115923?
- a.Yes, because the limit is 6 inches under the barrier
- b.Yes, because the sphere test is the test for gaps
- c.No, since the vertical clearance limit is 2 inches✓
- d.Yes, because gaps under 4 inches are allowed everywhere
The bottom clearance is limited to 2 inches, so 2-1/2 inches fails even though a 4-inch sphere cannot pass. Six inches is not the limit, and the sphere rule applies to gaps in the barrier, not the ground clearance.Cal. Health & Safety Code 115923(c)
A 25-foot ground-sleeve flagpole is ordered. What minimum hole size does one maker's table give?
- a.20 inches in diameter and 30 inches deep
- b.26 inches in diameter and 42 inches deep
- c.30 inches in diameter and 48 inches deep
- d.20 inches in diameter and 36 inches deep✓
The table gives 20 inches by 36 inches for a 25-foot pole. Twenty-six by 42 is the 30-foot pole, 20 by 30 is the 20-foot pole, and 30 by 48 mixes two columns.Flagpole maker installation instructions, Installation Instructions for Ground Sleeve Flagpoles
What minimum hole depth does the same table give for a 40-foot pole?
- a.60 inches
- b.48 inches
- c.54 inches✓
- d.42 inches
The 40-foot column gives a minimum depth of 54 inches. Forty-two is the 30-foot pole, 48 is the 33- and 35-foot poles, and 60 is not in the table.Flagpole maker installation instructions, Installation Instructions for Ground Sleeve Flagpoles
How is the ground sleeve bedded in one maker's instructions?
- a.6 inches of clay and a sleeve set flush with the grade
- b.3 inches of topsoil and a sleeve buried below grade
- c.12 inches of sand and no stone under the sleeve
- d.3 inches of stone, 3 of sand, sleeve top 1 inch up✓
The instructions place 3 inches of stone for drainage, then 3 inches of sand, and work the sleeve in until its top is 1 inch above grade. Clay, sand only and topsoil do not provide drainage, and the sleeve is not buried.Flagpole maker installation instructions, ground sleeve installation
How full is the foundation hole poured around the sleeve in the other maker's instructions?
- a.Half the height of the sleeve, then backfilled
- b.To the bottom of the sleeve, then left to dry
- c.Flush, or within an inch of the top of the sleeve✓
- d.To 6 inches above the top of the sleeve in a mound
The instructions fill until the cement is flush, or within an inch of the top of the sleeve, being careful to keep cement out of it. Half the height and bottom-only pours stop short of the stated fill level, and a mound above the sleeve top is not the flush fill the instructions give.Flagpole maker installation instructions, Preparation of the Foundation
How many people does one maker suggest to raise a 35-foot pole?
- a.Two or three people✓
- b.One person using a rope
- c.Ten people on both sides
- d.Six people on a long line
The maker suggests one or two people for 20- and 25-foot poles and two or three for 30- to 40-foot poles. One person cannot control a 35-foot pole, and six or ten is more than the maker states.Flagpole maker installation instructions, Raising the Flagpole
How is a ground-sleeve flagpole plumbed once it is standing in its sleeve?
- a.By adding water to the sleeve around the pole
- b.By tapping the pole with a hammer until it stands
- c.With shims or cedar shingles, left in place✓
- d.By removing and replacing the sleeve after the pour
The maker uses the play between pole and sleeve, plumbs with shims or cedar shingles, and leaves them in place before filling with dry sand. Hammering, water and sleeve replacement do not plumb a set pole.Flagpole maker installation instructions, Raising the Flagpole
What fills the space between the pole and the sleeve after the shims are placed?
- a.Wet concrete, poured to the top of the sleeve
- b.Foam sealant sprayed into the open gap
- c.Dry sand, packed firmly to the sleeve top✓
- d.Pea gravel mixed with water to settle it
The maker fills the space with dry sandbox or play sand to the top of the sleeve and packs it down firmly. Wet concrete would lock the pole in the sleeve, and gravel with water or foam is not the method.Flagpole maker installation instructions, Raising the Flagpole
How is the level checked on a flagpole sleeve in one maker's instructions?
- a.With a plumb bob dropped from the top of the pole
- b.With a level on two sides at 90 degrees to each other✓
- c.With one level held on one side of the sleeve
- d.By sighting down the pole by eye from the street
The instructions say to use a level on 2 sides 90 degrees to each other to check for plumb. One side only or sighting by eye misses lean in the other direction, and a plumb bob alone is not the stated method.Flagpole maker installation instructions, Preparation of the Foundation
A flagpole will be raised near an energized line. Which table clearance applies to material storage and boom-type equipment for lines of 600 to 50,000 volts?
- a.20 feet
- b.3 feet
- c.6 feet
- d.10 feet✓
Table 2 gives 10 feet for material storage and boom-type equipment for 600 to 50,000 volts, while Table 1's general clearance is 6 feet. Twenty and three feet are not table values.8 CCR 2946, Tables 1 and 2
Before a flagpole is erected near an overhead conductor, how is the conductor treated?
- a.As de-energized if it has no visible sag in the span
- b.As safe if the conductor wire is fully insulated
- c.As safe if the flagpole is made of aluminum tubing
- d.As energized until the owner verifies it is dead and grounded✓
Any overhead conductor is considered energized unless and until the owner verifies it is not energized and it is visibly grounded at the work site. A lack of sag, insulation on the wire and aluminum pole material do not change that, since insulation can fail and a metal pole conducts.8 CCR 2946(d)
Where are the snap hooks placed on a flagpole halyard?
- a.At the foot of the pole beside the sleeve
- b.At the cleat on the side of the pole
- c.At the top of the pole beside the pulley
- d.At a distance apart to suit the flag's size✓
The snap hooks are positioned the appropriate distance apart according to the size of the flag. The top, the cleat and the foot would not fit the flag.Flagpole maker installation instructions, flagpole assembly
How is the halyard secured at the cleat?
- a.Knotted to the pulley
- b.In a figure-8 on the cleat✓
- c.Tied to the finial
- d.Looped over the ball ornament
The halyard may be secured to the cleat in a figure-8 fashion. The pulley, the finial and the ball are at the top of the pole.Flagpole maker installation instructions, Raising the Flagpole
What does one flagpole maker's instruction say to do before digging the foundation hole?
- a.Dig 6 inches and then check
- b.Start with a power auger to save time
- c.Check for underground pipes and wires✓
- d.Check if the pole is over 30 feet
The maker says to check for underground pipes and wires, which under California law means calling 811 and waiting for the marks. Starting with a power auger, digging first and checking later, and checking only when a pole is tall do not meet that.Flagpole maker installation instructions; Cal. Gov. Code 4216.2
A flagpole sleeve is plumbed and the concrete has been poured. What is the next step before the pole is inserted in the other maker's method?
- a.Remove the sleeve
- b.Pour more concrete over the sleeve
- c.Allow the cement to dry✓
- d.Insert the pole and hoist the flag at once
The method says to allow the cement to dry before the pole goes in. Pouring more concrete over the sleeve would bury it, removing the sleeve would undo the plumbing, and inserting the pole and hoisting the flag at once would load wet cement.Flagpole maker installation instructions, Preparation of the Foundation
How does one flagpole maker instruction attach the ball ornament to the pole?
- a.Hammer the ball onto the top of the pole
- b.Glue the ball and leave the set screw loose
- c.Thread it on by the stem and tighten the set screw✓
- d.Tape the ball to the pulley at the top
The instruction threads the ball ornament on by the stem and tightens the set screw against the stem to hold it. Hammering the ball on, gluing it with the set screw loose and taping it to the pulley do not hold it securely.Flagpole maker installation instructions, flagpole assembly
A crew of 7 works a 6-hour shift where drinking water is not plumbed and there is no plan to bring more during the shift. At the least, how much water must be available at the start of the shift?
- a.84 quarts
- b.42 quarts✓
- c.7 quarts
- d.13 quarts
The rule is one quart per employee per hour for the whole shift, so 7 × 6 = 42 quarts when nothing is brought later (the standard lets an employer start with less only if it has effective replenishment procedures). Thirteen is the number of people plus hours, 7 is one quart each for one hour, and 84 doubles the requirement.8 CCR 3395(c)
The outdoor temperature is 82 degrees Fahrenheit. What does section 3395 require about shade?
- a.No shade is required until the temperature reaches 95
- b.Shade is needed if an employee asks for it first
- c.Shade is needed for employees new to the crew
- d.Shade must be present, since 82 exceeds the 80-degree trigger✓
Shade shall be present when the temperature exceeds 80 degrees, and 82 does. Ninety-five degrees is the trigger for high-heat procedures, not for shade, and shade does not wait for a request or apply only to new employees.8 CCR 3395(d)
The temperature is 96 degrees Fahrenheit. Which additional requirement applies?
- a.Nothing further, because shade and water already satisfy the rule
- b.High-heat procedures, with observation of employees and meetings✓
- c.A written warning to the foreman, and no other duties
- d.Work must stop for the rest of the day at that temperature
High-heat procedures apply when the temperature equals or exceeds 95 degrees, including effective communication, observation for signs of illness, designated emergency callers, water reminders and pre-shift meetings. The standard does not stop all work or reduce the duty to a warning.8 CCR 3395(e)
The predicted high is 91 degrees and the average high over the preceding five days was 80. What is the day?
- a.A heat wave, since 91 is 11 degrees above 80✓
- b.Not a heat wave, because it is under 95
- c.Not a heat wave, because the difference is under 15
- d.A heat wave when it reaches 100
A heat wave is a day whose predicted high is at least 80 and at least 10 degrees higher than the average high of the preceding five days. Ninety-one is 11 degrees above 80, so it qualifies. The 95-degree and 15-degree figures are not part of the definition.8 CCR 3395(g)(1)
A worker takes a preventative cool-down rest in the shade. How long must it last at the least, in addition to the time to reach the shade, before the worker is ordered back?
- a.30 minutes
- b.5 minutes✓
- c.1 minute
- d.15 minutes
The worker shall not be ordered back until signs or symptoms have abated, and in no event less than 5 minutes in addition to the time needed to reach the shade. One, fifteen and thirty minutes are not the minimum.8 CCR 3395(d)(3)
At what AQI for PM2.5 does the employer have to provide respirators for voluntary use under the wildfire smoke standard?
- a.51 or greater
- b.501 or greater
- c.101 or greater
- d.151 or greater✓
Where the current AQI is 151 or greater but does not exceed 500, the employer provides respirators for voluntary use and encourages their use. At 501 and above respirator use is required, and 51 and 101 are below the standard's threshold.8 CCR 5141.1(f)(3)
Which respirator type does the wildfire smoke standard name as an example for voluntary use?
- a.Surgical paper mask
- b.Cloth bandana
- c.Dust mask without NIOSH approval
- d.N95 filtering facepiece✓
The standard names NIOSH-approved devices such as N95 filtering facepiece respirators. A surgical mask, a bandana and an unapproved dust mask do not qualify.8 CCR 5141.1(f)(3)(A)
A claw hammer's handle is split. What does the Safety Orders say about it?
- a.It must be removed from service until it is repaired✓
- b.It may be wrapped with tape and kept in use
- c.It may still be used for light work if the head is tight
- d.It may be used on the ground, but not overhead
Tools with split or defective handles shall be removed from service and not reissued until repaired. Taping the handle, using the tool for light work with a tight head, and limiting it to ground work each keep a defective tool in use, which the section does not permit.8 CCR 1699(a)
A crew member must clear a jam in a pneumatic nailer. What is required first?
- a.Disconnect it from the air supply at the tool✓
- b.Pull the trigger to fire the jammed fastener out
- c.Keep the muzzle pressed on the work while clearing it
- d.Lower the air pressure at the compressor, then clear it
Pneumatic nailers and staplers shall be disconnected from the air supply at the tool when performing maintenance or repair or clearing a jam. Pulling the trigger, lowering pressure only and keeping the muzzle on the work leave the tool live.8 CCR 1704(c)
Who may operate equipment and machinery on a construction site?
- a.Only qualified persons chosen by the employer✓
- b.Any employee who is on the crew that day
- c.Any visitor who holds a driver's license
- d.The owner of the contracting firm
Title 8 says the employer shall permit only qualified persons to operate equipment and machinery. Anyone on the crew or any licensed driver is not enough, and operation is not limited to the owner.8 CCR 1510(b)
Under the fall-protection rule, at what exposure to a fall must personal fall arrest, restraint or positioning systems be worn?
- a.More than 7-1/2 feet✓
- b.More than 15 feet
- c.More than 30 feet
- d.More than 2 feet
Section 1670 requires systems for exposure to falling in excess of 7 1/2 feet from the perimeter of a structure or an unprotected edge. Two, fifteen and thirty feet are not the threshold.8 CCR 1670(a)
How high is the top rail of a standard Cal/OSHA construction railing?
- a.48 to 54 inches
- b.60 to 66 inches
- c.42 to 45 inches✓
- d.30 to 36 inches
The top rail is not less than 42 inches or more than 45 inches above the walking surface, with a mid-rail halfway between. The other ranges are not given.8 CCR 1620(a)(1)
A person on a road shoulder is exposed to public traffic during a dig. What must the employee wear?
- a.A half-face respirator with particulate filters
- b.Hearing protection with an attached face shield
- c.A warning vest or other high-visibility garment✓
- d.Fire-resistant coveralls with long sleeves
Employees exposed to public vehicular traffic shall be provided with and wear warning vests or other suitable garments marked with or made of reflectorized or high-visibility material. Hearing protection, fire-resistant clothing and a respirator do not make a worker visible.8 CCR 1541(d)
Silica dust may be produced when a crew cuts concrete. At what level is the action level for respirable crystalline silica defined?
- a.2.5 micrograms per cubic meter as a 1-hour average
- b.100 milligrams per cubic meter as a 15-minute average
- c.25 micrograms per cubic meter as an 8-hour average✓
- d.250 micrograms per cubic meter as an 8-hour average
The action level is 25 micrograms per cubic meter, calculated as an 8-hour time-weighted average. The other values change the number, the unit or the averaging time.8 CCR 1532.3(b)
A newly hired fence worker is assigned to a high-heat area. What does the standard require of the supervisor?
- a.Observe the worker during an announced heat wave
- b.Observe the worker on the first day of work
- c.Closely observe the worker for the first 14 days✓
- d.Nothing, because experienced workers are exempt from it
A newly assigned employee in a high-heat area is closely observed by a supervisor or designee for the first 14 days. Experience, one day or heat waves alone are not the limit.8 CCR 3395(g)(2)
Is an employer with fewer than 10 employees required to have a written Injury and Illness Prevention Program?
- a.No, if the employer's crews work at changing job sites
- b.Yes, but oral communication of safe practices is allowed✓
- c.Yes, and the program must be filed with the state yearly
- d.No, because small employers are exempt from the program
Every employer's Program is in writing; employers with fewer than 10 employees may communicate and instruct orally in general safe work practices as compliance with the communication element. Small and mobile employers are not exempt, and annual filing is not a stated requirement.8 CCR 3203(a)
Where is the written Code of Safe Practices posted?
- a.At each job site office, or provided to each supervisor✓
- b.In the glove box of the foreman's truck
- c.On the customer's front door during the job
- d.At the contractor's home office in the shop
Section 1509 posts the Code at each job site office or provides it to each supervisor who keeps it readily available. A home office, a front door and a glove box do not meet that.8 CCR 1509(c)
How often must supervisors conduct tailgate safety meetings at the least?
- a.At least every 10 working days✓
- b.Quarterly, at the start of each season
- c.Every 30 working days, once a month
- d.Daily, before each shift begins
Section 1509 requires toolbox or tailgate meetings at least every 10 working days. Daily meetings are not required, and 30 working days or a quarter is too seldom.8 CCR 1509(e)
A new employee starts work on a fence crew. What must the employer give at the start?
- a.A map of the job sites for the coming week
- b.Hazard instruction and a direction to read the Code✓
- c.A tax form, a time card and a work schedule
- d.A written warning about the crew's past injuries
When workers are first employed they receive instructions regarding the hazards and safety precautions applicable to the work and are directed to read the Code of Safe Practices. A job-site map, tax and schedule paperwork, and a warning about past injuries are not safety instructions.8 CCR 1510(a)
Before employees are on a new site, what must the employer do about the site conditions?
- a.Skip the survey if the job lasts under a week
- b.Wait for the first injury and then survey it
- c.Ask the customer to inspect the site for hazards
- d.Survey the site for the predictable hazards beforehand✓
Section 1511 requires the employer to survey the conditions of the site beforehand to determine the predictable hazards and safeguards. Waiting for an injury, delegating to the customer or skipping short jobs does not meet it.8 CCR 1511(b)
What first-aid kit must an employer provide on a construction project?
- a.A kit that is stocked once and not inspected again
- b.A kit kept at the contractor's main office
- c.At least one weatherproof kit that is inspected regularly✓
- d.A kit if the crew has more than 200 employees
The employer provides at least one first-aid kit in a weatherproof container, and its contents are inspected regularly so expended items are promptly replaced. A kit that is never inspected goes stale, a kit left at the main office is not at the project, and the 200-employee threshold applies only to some supplies, not to having a kit.8 CCR 1512(c)
A crew of 4 works on a fence far from any facility, but with a truck that can reach a toilet quickly. What does section 1526 say?
- a.No sanitation is required on private land of any kind
- b.Two toilets are required for any crew, whatever its size
- c.A separate toilet must be provided for each worker
- d.The rule does not apply to mobile crews with ready transport✓
The section does not apply to mobile crews having readily available transportation to nearby toilet facilities. A separate toilet for each worker and two toilets per crew are not stated, and private land is not an exemption from sanitation rules.8 CCR 1526(e)
How must drinking-water containers be handled on a site?
- a.Unmarked jugs may be used by anyone on the job
- b.A single shared cup is fine for the whole crew
- c.No dipping from them, and no sharing of cups✓
- d.Water may be dipped out with one shared cup
The section says water shall not be dipped from containers and that individual containers and cups are not shared or used in common; individual containers are marked. Shared cups and unmarked jugs do not comply.8 CCR 1524
