Question 1

What is the primary function of an 'Engineering Control' when dealing with a deadly hazard?

Accepted Answer

Physically modifying the tool, the machine, or the chaotic environment itself to automatically remove or capture the hazard at its source, requiring zero effort or thought from the stressed employee

Answer

Handing out specialized masks and gloves to the crew

Answer

Yelling at the workers to be careful

Answer

Writing a new set of rules in an office manual

Question 2

What is the strict rule regarding 'Spoil Piles' (the mounds of excavated dirt) next to a trench?

Accepted Answer

The spoil pile must be kept a minimum of exactly 2 feet away from the edge of the trench to prevent the heavy dirt from cascading back down onto the workers

Answer

They must be instantly hauled off-site the second they are dug

Answer

They must be placed exactly on the edge to act as a handrail

Answer

There are no rules regarding the dirt placement

Question 3

A contractor uses a massive specialized forklift (powered industrial truck). What is the strict OSHA training requirement for the operator?

Accepted Answer

The employer must ensure the operator is formally trained, evaluated, and certified in writing by a competent person specifically on that exact type of forklift, and re-evaluated at least every 3 years

Answer

The operator only needs a standard Class C California Driver's License

Answer

The operator must read the forklift's manual cover-to-cover

Answer

There are no training requirements as long as the worker drives slowly

Question 4

A contractor is erecting a massive tube-and-coupler metal scaffold that will exceed 36 feet in height (or 3 stories). What is legally required?

Accepted Answer

A specialized Cal/OSHA Scaffolding Permit must be obtained prior to erection, and the design must usually be approved by a qualified engineer

Answer

A permit from the Federal Aviation Administration (FAA)

Answer

A minimum of 50 warning signs at the base

Answer

Only the homeowner's written permission

Question 5

If a highly skilled electrician refuses to tag out a breaker because 'it will only take two seconds' to wire a switch hot, and they are tragically electrocuted and killed, can Cal/OSHA still violently fine the employer?

Accepted Answer

Absolutely yes; if the employer aggressively failed to enforce their safety rules in the past (allowing a culture of hot work), the employer is incredibly liable for an 'Ineffective IIPP' or 'Willful' violation despite the worker's bad choice

Answer

No, electrocutions are considered unpredictable 'Acts of God'

Answer

No, the fault is 100% on the dead employee

Answer

Only if the employer physically forced them to do it

Question 6

If a worker gets to the job site and discovers the scaffolding is wobbly and missing guardrails, they refuse to climb it. Can the employer fire them for refusing to work?

Accepted Answer

Absolutely not; California Labor Code explicitly prohibits retaliating against or firing an employee who refuses to perform work that would create a real, apparent hazard to their safety

Answer

No, unless the scaffolding is less than 10 feet high

Answer

Yes, 'at-will' employment means an employer can force a worker to do anything

Answer

Yes, but the employer must give them 2 weeks severance pay

Question 7

When workers are exposed to loud noise (e.g., jackhammers), at what exact noise level averaged over an 8-hour shift must an employer institute a mandatory Hearing Conservation Program?

Accepted Answer

An 8-hour Time-Weighted Average (TWA) of 85 decibels (dBA)

Answer

120 dBA

Answer

50 dBA

Question 8

What is the proper, safe angle for setting up a non-self-supporting portable ladder leaning against a wall?

Accepted Answer

Answer

Straight up and down completely vertical

Answer

A 10-to-1 ratio

Answer

A 1-to-1 ratio (45-degree angle)

Question 9
