CSLB B-2 Residential Remodeling (Trade Exam) — All Questions

How often must supervisors hold tailgate meetings under Cal/OSHA's construction safety orders?

• a.At least every 10 working days✓
• b.Once a year, at the annual safety meeting
• c.Every day, before the crew starts work
• d.Every month

Supervisors hold toolbox or tailgate meetings at least every 10 working days. Daily meetings are more often than required, a monthly or yearly schedule is too infrequent.8 CCR 1509(e)

A new hire's first day requires what under section 1510?

• a.No training at all until they have finished their first full week
• b.Hazard instruction and direction to read the Code of Safe Practices✓
• c.A company uniform and a locker for their personal tools and belongings
• d.A written test covering the work they performed on their earlier jobs

Section 1510 requires instruction in hazards and precautions and a direction to read the Code of Safe Practices. A written test, a uniform and no training are not what it requires.8 CCR 1510(a)

Which standard does Cal/OSHA name for hard hats?

• a.UL 127
• b.ASTM C926
• c.ANSI/ISEA Z89.1✓
• d.ANSI A108

Head protection meets ANSI/ISEA Z89.1. ANSI A108 is a tile installation standard, UL 127 covers fireplaces, and ASTM C926 covers plaster application.8 CCR 3381(b)

At what outdoor temperature does the high-heat procedures rule start?

• a.100 degrees Fahrenheit
• b.95 degrees Fahrenheit✓
• c.80 degrees Fahrenheit
• d.105 degrees Fahrenheit

High-heat procedures start at 95 degrees Fahrenheit. Eighty degrees is the threshold for shade, and 100 and 105 degrees are higher than the trigger.8 CCR 3395(e)

When is voluntary use of a respirator allowed?

• a.If the respirator is brand new and still in its box
• b.Never
• c.When use will not itself create a hazard✓
• d.Whenever the employee simply likes the respirator better

Voluntary use is permitted when the employer determines it will not itself create a hazard. Employee preference, a new respirator and a blanket ban are not the test.8 CCR 5144(c)(2)

A portable ladder is used to reach a roof edge. How far above the landing must the side rails extend?

• a.At least 24 inches
• b.At least 60 inches
• c.At least 36 inches✓
• d.At least 12 inches

Side rails extend at least 36 inches above the landing so the climber can grasp them. Twelve and twenty-four inches are too short, and 60 inches is more than required.8 CCR 3276(e)(11)

A 20-foot ladder is set at the preferred pitch. How far from the wall is the foot?

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

One-quarter of the working length: 20 ÷ 4 = 5 feet. Two feet is one-tenth, 10 feet is half, and 20 feet is the full length.8 CCR 3276

Which ladders may not be used in construction?

• a.Extension ladders
• b.Step ladders with metal side rails
• c.Single-rail ladders✓
• d.Job-made ladders meeting section 1676

Single-rail ladders are not used in construction. Extension ladders, step ladders and job-made ladders built to the safety order are allowed.8 CCR 1675(d)

At what fall exposure must personal fall arrest generally be worn?

• a.Above 2 feet from edges
• b.Above 4 feet from edges
• c.Above 25 feet from edges
• d.Above 7-1/2 feet from edges✓

Personal fall arrest is worn where exposure exceeds 7-1/2 feet from perimeters and edges. Two and four feet are lower than the threshold, so they would require protection the rule does not call for, and 25 feet is higher, so it would leave workers unprotected between 7-1/2 and 25 feet.8 CCR 1670(a)

How far may a scaffold plank overhang its support unprotected?

• a.18 inches✓
• b.6 inches
• c.36 inches
• d.24 inches

Removal of ACM floor tile is Class II work. Class I is thermal insulation and surfacing, Class III is repair and maintenance likely to disturb ACM, and Class IV is custodial work.8 CCR 1529

What is the Cal/OSHA lead PEL?

• a.50 micrograms per cubic meter
• b.10 micrograms per cubic meter✓
• c.100 micrograms per cubic meter
• d.2 micrograms per cubic meter

The PEL is 10 micrograms per cubic meter as an 8-hour average. Two is the action level, 50 is the silica PEL and 100 is not a limit in the standard.8 CCR 1532.1(c)

At what quantity of ACM must a contractor hold C-22 or asbestos certification?

• a.50 square feet or more
• b.10 square feet or more

An employer's Injury and Illness Prevention Program must be handled how under section 1509?

• a.Established, implemented and maintained✓
• b.Kept in the owner's head, never written down
• c.Posted in the office and not shared with crews
• d.Required only after an employee is injured

Every employer establishes, implements and maintains an effective program under section 3203, and adopts a written Code of Safe Practices. A mental plan, an office-only posting and an after-injury rule do not meet that.8 CCR 1509(a)

Under section 1510(a), who must be given hazard instruction and told to read the Code of Safe Practices at the time of initial employment?

• a.Only visitors to the site
• b.Each new worker✓
• c.Only workers with a prior injury

• a.It may be worn by supervisors
• b.It may be worn if taped
• c.It shall not be worn✓
• d.It may be worn on dry days

Defective or inappropriate footwear shall not be worn. Taping, dry weather and a supervisor's status do not make it safe.8 CCR 3385(b)

At 90 degrees outdoors, what must the employer have present?

• a.A fan, blowing on the working crew
• b.Shade when it is above 100 degrees
• c.Nothing, since 90 degrees is not high heat
• d.Shade, since it is above 80 degrees✓

Shade must be present above 80 degrees. Nothing would violate the rule, shade only above 100 degrees is too high a trigger, and a fan is not shade.8 CCR 3395(d)

At 96 degrees, what rest is ensured?

• a.A ten-minute cool-down rest every two hours✓
• b.None
• c.A one-minute break taken at the top of every hour
• d.A thirty-minute rest taken once every four hours

Which ladder angle is preferred for a single ladder?

• a.Foot distance one-tenth of the working length
• b.Foot distance equal to the working length of the ladder
• c.Foot distance of one-quarter the working length✓
• d.Foot against the wall, so the ladder stands vertical

The foot is one-quarter of the working length from the support. Equal to the working length would lay the ladder flat, one-tenth is too steep, and the foot against the wall is vertical.8 CCR 3276(e)(9)

What is three-point contact on a ladder?

• a.Three fingers
• b.Two feet and one hand✓
• c.Both feet and the knee
• d.One hand and one knee

Three-point contact is two feet and one hand, or two hands and one foot. Both feet and a knee, one hand and one knee and three fingers do not give secure support.8 CCR 3276

A ladder is occupied. What may not be done?

• a.It may be climbed
• b.It may not be moved✓
• c.It may be leaned on a wall
• d.It may be inspected

A wall opening with a 5-foot drop has its bottom 2 feet above the floor. What is required?

• a.It must be guarded✓
• b.Nothing
• c.A tape line across the opening
• d.A warning sign posted at the opening

An opening with a drop over 4 feet and a bottom under 3 feet above the surface is guarded. Nothing, a sign alone and a tape line alone do not guard it.8 CCR 1632(j)

What does the scaffold standard say about platforms?

• a.Left unsecured, since weight holds them
• b.Sloped 4 to 1 so that debris slides off
• c.Not sloped more than 2 feet in 10 feet✓
• d.Sloped 4 feet in 10 feet to shed water

Platforms are not sloped more than 2 feet vertically in 10 feet horizontally and are secured against slipping. A 4-feet-in-10 slope or a 4-to-1 slope is far steeper than allowed, and leaving platforms unsecured is not allowed.8 CCR 1637(o)

When are guardrails installed on a scaffold?

• a.Never
• b.Above 30 feet
• c.Before other work not related to erection begins✓
• d.After the scaffold work is completely finished

Guardrails go on before other work not related to erection begins. After the job, never and only above 30 feet are not the rule.8 CCR 1637

Combustible debris inside a building during work must be handled how?

• a.Burned on site

Deficiencies found in the survey are shored, braced or corrected before demolition. Ignoring, merely noting or fixing them after demolition leaves the hazard.8 CCR 1735(d)

In what order is exterior wall and floor demolition done?

• a.Sides first
• b.Random
• c.Top down✓
• d.Bottom up

Exterior walls and floors are demolished from the top down, story by story. Bottom up, random and sides-first sequences remove support and endanger workers.8 CCR 1735(f)

How high is an unbraced free-standing wall section allowed to stand?

• a.One story or 12 feet, without lateral bracing✓
• b.30 feet
• c.50 feet
• d.Any height at all, as long as the wall is plumb

A wall section more than one story or 12 feet high needs lateral bracing unless an engineer's data shows it can stand. Any height, 30 feet and 50 feet are not the rule.8 CCR 1735(m)

What is the asbestos PEL?

• a.100 fibers per cubic centimeter as an 8-hour average
• b.1 fiber per cubic centimeter
• c.10 fibers per cubic centimeter
• d.0.1 fiber per cubic centimeter, 8-hour average✓

What does the demolition rule require for dust?

• a.Water or equivalent steps✓
• b.Opening a window to let dust out
• c.Dry sweeping at the end of the day
• d.Nothing, if the work is short

Dust control uses water or equivalent steps. Dry sweeping raises dust, opening a window does not control it, and doing nothing violates the rule.8 CCR 1735(t)

Where are fuel gas cylinders stored on a job?

• a.Valve end down, to keep any gas from escaping
• b.Loose on the floor, where crews can reach them
• c.Valve end up, secured, kept out of confined spaces✓
• d.Inside confined spaces, to keep them out of the weather
