269 questions
A crew will dig on Thursday. Which statement about the notice is correct?
- a.The day of the call counts as the first of the two days
- b.The call may be made on Thursday morning before work
- c.Call at least two working days ahead, excluding the call day✓
- d.No call is needed when the work is on private property
The notice is at least two working days and the date of the notification does not count. Calling the morning of the dig is too late, and the statute does not exempt private property.Cal. Gov. Code 4216.2(b); 8 CCR 1541(b)(2)
A crew digs a hole 3 feet deep in firm soil. A competent person sees no sign of a cave-in. Is a protective system required?
- a.Yes, for any hole that is deeper than 2 feet
- b.Yes, a protective system is needed for a hole this deep
- c.Yes, unless the soil happens to be wet
- d.No, since it is under 5 feet with no sign of cave-in✓
Section 1541.1 does not require a protective system when the excavation is less than 5 feet deep and a competent person finds no indication of a potential cave-in. A hole of 3 feet is under that limit, so the 2-foot rule, a blanket requirement for a hole this deep and a wet-soil condition are not in the section.8 CCR 1541.1(a)(1)(B)
At what trench depth must a stairway, ladder, ramp or other egress be located so as to require no more than 25 feet of lateral travel?
- a.4 feet or more✓
- b.2 feet or more
- c.8 feet or more
- d.12 feet or more
Trench excavations 4 feet or more deep need a safe means of egress within 25 feet of lateral travel. Two, eight and twelve feet are not the threshold.8 CCR 1541(c)(2)
What must the employer have for each hazardous chemical it uses, such as a concrete product or a wood preservative?
- a.A purchase order
- b.A photo of the label
- c.A safety data sheet✓
- d.A receipt for the product
Title 8 requires employers to have a safety data sheet for each hazardous chemical they use, under the written hazard communication program. A receipt, a photo and a purchase order do not give the hazard information.8 CCR 5194(g)(1)
A post-hole auger strikes a natural gas line and gas escapes. What does the Government Code require the excavator to do first?
- a.File a report with the state next month
- b.Immediately call 911 emergency services✓
- c.Call the neighbor and ask for advice
- d.Wait to see if the leak stops by itself
The excavator must immediately call 911 when damage to a gas or hazardous liquid pipeline results in the escape of a flammable, toxic or corrosive gas or liquid, and then contact the operator. Reporting next month, asking a neighbor and waiting for the leak to stop all delay the emergency call.Cal. Gov. Code 4216.4(c)(1)
After damaging a subsurface installation, how soon must the excavator notify the regional notification center?
- a.Within 24 hours of the ticket expiring
- b.Within 7 days
- c.When asked
- d.Within 48 hours✓
The excavator shall notify the center within 48 hours of discovering or causing damage to any subsurface installation. Seven days or waiting to be asked is too slow, and the ticket expiry is not the trigger.Cal. Gov. Code 4216.4(c)(3)
An excavator finds a buried line that appears abandoned. How should it be treated?
- a.As safe to cut, since it carries no service
- b.As unimportant, since it is not on the ticket
- c.As the property of the landowner, to be removed
- d.As active, with the same care as an active line✓
The excavator shall presume all subsurface installations are active and use the same care around those that may be inactive. A line that looks abandoned may still carry service, a line missing from the ticket is still there, and ownership by the landowner does not make it safe to remove.Cal. Gov. Code 4216.4(a)(3)
What does the air district notice say about chemically treated wooden stakes and end posts?
- a.They may be burned when they are fully dry
- b.They may not be burned or chipped at any time✓
- c.They may be chipped and used as garden mulch
- d.They may be used as firewood in a home stove
The notice says chemically treated wooden stakes and end posts may not be burned or chipped at any time, and may not be sold as firewood. Dry burning, mulch and firewood are the uses it rules out.San Joaquin Valley APCD, Chemically Treated Wood Waste Disposal (AB 332)
Wood preservatives are described by the Forest Products Laboratory as what?
- a.Harmless oils that need no label review
- b.Paints that color the wood surface
- c.Decorative stains with no biocide in them
- d.Fungicides, which are classed as pesticides✓
The bulletin says wood preservatives contain fungicides and fungicides are pesticides, so the label directions apply. They are not harmless oils, paints or only stains.USDA Forest Products Laboratory, Protecting Wood Fences for Yard and Garden
Applying a water-repellent preservative by spray rather than brush can cause what?
- a.Faster curing of concrete
- b.Better penetration into wood
- c.Stronger posts
- d.Drift onto non-target areas✓
The bulletin says spraying can easily contaminate non-target areas with drift, and that brushing improves penetration and lessens the environmental hazard. Spraying does not affect concrete or strength.USDA Forest Products Laboratory, Protecting Wood Fences for Yard and Garden

How does the bulletin say pesticides should be stored?
- a.In an empty milk jug marked with a pen
- b.In unlabeled jars kept on a shelf in the shop
- c.In the cab of the truck with the tools
- d.In original containers, away from children✓
The bulletin says to store pesticides in original containers, out of reach of children and pets. Unlabeled jars, a cab or a food container are unsafe.USDA Forest Products Laboratory, Protecting Wood Fences for Yard and Garden
Why should concrete washwater not be dumped on the ground, according to the EPA fact sheet?
- a.It can run to storm drains and on to surface waters✓
- b.It evaporates at once without leaving residue
- c.It will make the soil stronger around the posts
- d.It is harmless if it is diluted with some water
The fact sheet says washwater dumped on the ground can run off the site to adjoining roads and enter storm drains that discharge to surface waters. It is caustic, not helpful to soil, and not harmless because of dilution.EPA, Stormwater Best Management Practice: Concrete Washout
What is the EPA fact sheet's objective for concrete washout?
- a.Bury it in the post hole with the extra concrete
- b.Discharge it through a hose to the nearest street
- c.Let it dry on the bare soil beside the work
- d.Collect all of it in leak proof containers✓
The objective is to collect and retain all the washout water and solids in leak-proof containers so the caustic material does not reach soil or surface water. Street discharge, burying and drying on soil do not collect it.EPA, Stormwater Best Management Practice: Concrete Washout
According to the conservation standard, how should a fence be designed, located and installed with regard to wildlife?
- a.To keep wildlife off the property with a continuous barrier
- b.To draw wildlife along the fence line for easy viewing
- c.To minimize impacts on local wildlife as appropriate✓
- d.To leave wildlife out of the plan unless the owner asks
The standard says to design, locate and install fences to minimize impacts on local wildlife as appropriate. Drawing animals to the fence line, sealing the property with a continuous barrier and leaving wildlife out of the plan each ignore that instruction.NRCS Conservation Practice Standard 382, Fence
How does the conservation standard say to handle old fence material removed during construction?
- a.Dispose of it properly so no one is harmed✓
- b.Burn it on the site in a pile after clearing
- c.Leave it in the pasture where it came down
- d.Bury it along the fence line in a trench
The standard calls for proper disposal of removed fencing materials to prevent harm to animals, people or equipment. Leaving the material in the pasture leaves a hazard, and burying it in a trench or burning it in a pile on site is not proper disposal.NRCS Conservation Practice Standard 382, Fence
Why handle wet concrete with care, according to the EPA fact sheet?
- a.It sets when it is in direct sun
- b.It is cold enough to cause frostbite
- c.It shrinks steel tools that touch it
- d.It can irritate skin and damage the eyes✓
The fact sheet says construction workers should handle wet concrete and washout water with care because it may cause skin irritation and eye damage. Wet concrete is not cold enough to cause frostbite, it does not shrink steel tools, and setting in the sun is not a hazard to the worker.EPA, Stormwater Best Management Practice: Concrete Washout
After a utility line is struck, who must the excavator contact immediately besides emergency services when gas is escaping?
- a.The operator of the damaged line itself✓
- b.The local newspaper that covers the area
- c.The county assessor who maps the parcel
- d.The customer's lender for the project
After calling 911 the excavator must contact the operator immediately, and later notify the regional notification center within 48 hours. The assessor, a lender and a newspaper have no role.Cal. Gov. Code 4216.4(c)(2)
What do the Caltrans specifications say to do with surplus excavated material from fence construction?
- a.Burn it in a pile on the right-of-way
- b.Spread it evenly along the adjacent roadway✓
- c.Pile it up against the finished fence line
- d.Dump it in a storm drain at the end of the day
Caltrans says to uniformly spread surplus excavated material along the adjacent roadway where designated by the Engineer. Burning it on the right-of-way, piling it against the finished fence and dumping it in a storm drain all leave it where it does not belong or pollute water.Caltrans 2024 Standard Specifications 80-1.03
What does the Forest Products Laboratory say about vapor from wood treated with pentachlorophenol?
- a.It is harmless to plants and leaves nearby
- b.It affects metal fittings and hardware
- c.It feeds plants with a mild nutrient
- d.It may poison plants and burn leaves that touch it✓
The bulletin says vapor from wood treated with pentachlorophenol may poison plants and burn leaves that contact the wood. It is not harmless, nutritive or limited to metal.USDA Forest Products Laboratory, Protecting Wood Fences for Yard and Garden
