CSLB General Building (B) — All Questions

Under Cal/OSHA, before requiring employees to wear respirators, an employer must generally do what?

• a.Nothing; respirators can be handed out freely
• b.Establish a written respiratory protection program including hazard assessment, medical evaluation, and fit testing✓
• c.Only provide dust masks with no training
• d.Wait until an employee complains of symptoms

Cal/OSHA's respiratory protection standard requires a written program with hazard evaluation, medical clearance, proper respirator selection, training, and fit testing before employees use required respirators. This ensures the respirator is appropriate and the worker can use it safely. Voluntary-use situations have their own requirements.Cal/OSHA Title 8

When using a solvent-based coating in an enclosed room, what is the primary way to control flammable vapor and inhalation hazards?

• a.Provide adequate ventilation and remove ignition sources, using respiratory protection as needed✓
• b.Light a candle to test the air
• c.Seal all openings to trap the vapors
• d.Increase the room temperature to speed evaporation

Solvent vapors are both toxic and flammable, so enclosed spaces require adequate ventilation to keep concentrations low and all ignition sources removed. Respiratory protection is used when ventilation alone is insufficient. Cal/OSHA and fire codes address both the health and explosion hazards of solvents.Cal/OSHA Title 8

What is a key requirement when setting up an extension ladder against a wall?

• a.Lean it as steeply as possible
• b.Place the base right at the wall
• c.Set it at roughly a 4-to-1 ratio (base one foot out for every four feet of height) and secure it against slipping✓
• d.Rest it on a stack of paint cans for height

A stable extension ladder is positioned so the base is about one foot away from the wall for every four feet of working height, giving roughly a 75-degree angle. It should be on firm, level ground and secured against slipping, extending above the landing when used for access. This reduces the risk of the ladder kicking out or tipping.Cal/OSHA Title 8

Cal/OSHA generally requires fall protection for workers on scaffolds or elevated surfaces above what approximate height?

• a.20 feet
• b.Guardrails or personal fall protection are required at relatively low heights (commonly around 6-7.5 feet depending on the situation)✓
• c.50 feet
• d.Fall protection is never required for painters

Cal/OSHA requires guardrails or personal fall-arrest systems on scaffolds and elevated work at relatively low trigger heights, often in the range of about 6 to 7.5 feet depending on the type of work and platform. The exact trigger depends on the specific Title 8 section. Painters frequently work at heights and must plan fall protection accordingly.Cal/OSHA Title 8

Why is lead exposure a special concern during paint removal on older buildings?

• a.Lead dust and chips are toxic, especially to children, and can be inhaled or ingested✓
• b.Lead makes paint dry too slowly
• c.Lead improves indoor air quality
• d.Lead is only a concern in new construction

Lead is a potent toxin that damages the nervous system, and children are especially vulnerable to lead dust and chips created during sanding or scraping old paint. This is why the EPA RRP Rule and Cal/OSHA lead standards require containment, safe work practices, and worker protection on pre-1978 buildings. Uncontrolled lead dust endangers both workers and occupants.EPA RRP Rule

What control best reduces respirable crystalline silica exposure when sanding or grinding concrete?

• a.Working faster to finish sooner
• b.Using a household fan to blow dust around
• c.Wet methods or tools with vacuum dust collection (HEPA), plus respiratory protection when needed✓
• d.Sweeping the dry dust with a broom

Silica dust is controlled at the source using water suppression or tools fitted with HEPA vacuum dust collection, which is the preferred engineering control under Cal/OSHA. Respiratory protection supplements these controls when exposures remain high. Dry sweeping and blowing dust make exposures worse.Cal/OSHA Title 8

How should solvent-soaked rags be handled to prevent a fire?

• a.Piled loosely in a corner overnight
• b.Stored in a closed, labeled metal container and disposed of as hazardous waste✓
• c.Thrown in the regular trash while still wet
• d.Left spread out on wood surfaces in the sun

Rags soaked in oil-based products or solvents can self-heat and spontaneously combust when piled up, so they must be kept in a closed metal container until proper disposal. They are handled as hazardous waste, not ordinary trash. This simple practice prevents a common cause of jobsite fires.

What is required before a worker enters a permit-required confined space, such as a tank being coated?

• a.Atmospheric testing, ventilation, and a permit/entry procedure with an attendant✓
• b.Only a flashlight
• c.Nothing special is needed
• d.Just a quick look inside

Permit-required confined spaces can contain toxic or oxygen-deficient atmospheres, especially when solvent coatings are applied, so Cal/OSHA requires air monitoring, ventilation, a written permit, and an attendant outside. Entry without these controls has caused fatalities. A rescue plan must also be in place before entry.Cal/OSHA Title 8

Where should a painter look first to learn the specific hazards and protective measures for a coating or solvent?

• a.The color chart
• b.The price tag
• c.The Safety Data Sheet (SDS) for that product✓
• d.The paint can's barcode

The Safety Data Sheet lists a product's hazards, required personal protective equipment, first aid, handling, and disposal information. Employers must make SDSs accessible to workers under the hazard communication standard. Reviewing the SDS is the correct first step for handling any chemical safely.

What type of respirator is generally appropriate for organic solvent vapors (not just dust)?

• a.A simple paper dust mask
• b.An air-purifying respirator with organic-vapor cartridges (or supplied air when required)✓
• c.No respirator is needed for solvents
• d.A cloth bandana

Organic solvent vapors require a respirator with organic-vapor chemical cartridges, not a particulate dust mask, which only filters particles. In high concentrations or confined spaces, supplied-air respirators may be required. Respirator selection must follow the written respiratory protection program and the exposure assessment.Cal/OSHA Title 8

Which is a required safe practice when working on a supported scaffold?

• a.Fully plank the platform, use guardrails or fall protection, and ensure the scaffold is level and on a firm footing✓
• b.Use a single narrow plank with no rails
• c.Overload the platform with all the paint at once
• d.Climb the cross-braces instead of using a ladder

Scaffolds must be fully planked, equipped with guardrails or personal fall protection, and erected level on firm, adequate footing per Cal/OSHA. Workers should access platforms by proper ladders or stairs, not by climbing braces, and must not overload the scaffold. Competent-person inspection is required before each shift.Cal/OSHA Title 8

How should leftover paint and empty containers generally be disposed of?

• a.Poured down a storm drain
• b.Dumped in a creek
• c.According to hazardous-waste and local regulations; latex may be dried out and many areas offer paint recycling✓
• d.Buried anywhere on the jobsite

Paint and solvents can be hazardous, so disposal must follow local and hazardous-waste regulations rather than dumping into drains, waterways, or soil. Dried latex is often accepted differently than solvent-based products, and California has paint stewardship recycling programs. Proper disposal protects the environment and avoids fines.

What is the main reason to keep a fire extinguisher accessible when spraying solvent-based coatings?

• a.To weigh down the drop cloths
• b.Atomized solvent-based paint and vapors are flammable, so a fire could ignite and must be controllable✓
• c.Extinguishers improve spray finish
• d.It is only decorative

Spraying solvent-based coatings creates a flammable mist and vapor that can ignite from sparks or static, so a suitable fire extinguisher must be readily available. Bonding and grounding of equipment and eliminating ignition sources further reduce the risk. Fire safety planning is essential for solvent spray operations.Cal/OSHA Title 8

What personal protective equipment is typically appropriate when spraying paint overhead?

• a.Eye protection, respiratory protection, and appropriate skin/coverall protection✓
• b.Only gloves
• c.No PPE is needed for overhead spraying
• d.Just a hat

Overhead spraying showers mist and overspray downward, so the painter needs eye protection, a respirator suited to the coating, and coveralls or skin protection. The specific respirator depends on whether the hazard is particulate or solvent vapor per the SDS and exposure assessment. Matching PPE to the task and product protects the worker.

What is the employer's role regarding training painters on jobsite hazards?

• a.Training is optional and rarely provided
• b.Only new painters over 40 need training
• c.Employers must provide hazard communication and task-specific safety training so workers understand chemical and physical hazards and controls✓
• d.Workers must pay for all their own training with no employer role

Cal/OSHA requires employers to train workers on the hazards they face, including hazard communication for chemicals, plus specific training for tasks like ladder use, fall protection, respirators, and lead or silica work. Effective training helps workers recognize and control hazards. It is a core part of the employer's Injury and Illness Prevention Program.Cal/OSHA Title 8
