What this exam covers

Exposure Control Plan Inspection and Implementation Duties (1926.1153)100%

5 real sample questions

What must a written exposure control plan describe?

A. The tasks that involve silica exposure, the controls and respiratory protection used for each task, the housekeeping measures used, and the procedures to restrict access to work areas

B. Only the company's general safety mission statement

C. Only the brand names of tools purchased that quarter

D. Only employees' personal medical histories

Show answer and reasoning

Correct answer: A. The tasks that involve silica exposure, the controls and respiratory protection used for each task, the housekeeping measures used, and the procedures to restrict access to work areas

B: A general mission statement is not the specific content the standard requires.
C: Tool brand names are not required plan content.
D: Personal medical histories belong to the medical surveillance program, not the exposure control plan.

Source: 1926.1153(g)(1)

Under the silica standard, what makes someone a "competent person"?

A. The ability to identify existing and foreseeable respirable crystalline silica hazards, combined with authorization to take prompt corrective measures

B. Owning a personal air-monitoring device

C. Having completed a general OSHA 10-hour course, with no silica-specific content

D. Being the employee who orders the dust-control equipment

Show answer and reasoning

Correct answer: A. The ability to identify existing and foreseeable respirable crystalline silica hazards, combined with authorization to take prompt corrective measures

B: Owning a device does not establish the ability to identify hazards or the authority to correct them.
C: A general course without silica-specific competency does not meet this standard's definition.
D: Ordering equipment is a procurement task, not the hazard-identification-plus-authority the definition requires.

Source: 1926.1153(b): Competent person, definition

What specific duty does 1926.1153(g)(4) assign to a designated competent person?

A. To make frequent and regular inspections of job sites, materials, and equipment to implement the written exposure control plan

B. To personally perform every employee's medical surveillance exam

C. To manufacture the dust-suppression equipment used on site

D. To set the company's wage rates for silica-exposed trades

Show answer and reasoning

Correct answer: A. To make frequent and regular inspections of job sites, materials, and equipment to implement the written exposure control plan

B: Medical exams are performed by a licensed healthcare provider, not the competent person.
C: Manufacturing equipment is not a duty this standard assigns.
D: Wage-setting is unrelated to the competent person's inspection duty.

Source: 1926.1153(g)(4)

For a task listed on Table 1, what must the employer do?

A. Fully and properly implement the engineering controls, work practices, and respiratory protection specified for that task on Table 1

B. Choose any combination of controls the employer prefers, regardless of what Table 1 lists

C. Ignore Table 1 if the crew has performed the task before without incident

D. Use Table 1 only as an optional suggestion

Show answer and reasoning

Correct answer: A. Fully and properly implement the engineering controls, work practices, and respiratory protection specified for that task on Table 1

B: Substituting a different combination without following Table 1 does not satisfy this compliance path.
C: Past experience without incident does not exempt a task from the required controls.
D: Table 1 is a required control specification for listed tasks, not an optional suggestion.

Source: 1926.1153(c)

What is the permissible exposure limit (PEL) for respirable crystalline silica under this standard?

A. 50 micrograms per cubic meter of air (μg/m³), calculated as an 8-hour time-weighted average

B. 250 μg/m³, calculated as an 8-hour time-weighted average

C. 50 milligrams per cubic meter of air, calculated as a 15-minute average

D. There is no numeric PEL; only Table 1 compliance is required

Show answer and reasoning

Correct answer: A. 50 micrograms per cubic meter of air (μg/m³), calculated as an 8-hour time-weighted average

B: Five times too high; that is not the standard's PEL.
C: Wrong unit (milligrams, not micrograms) and wrong averaging period.
D: A numeric PEL does exist under (d)(1); Table 1 is one path to controlling exposure, but the PEL itself is defined.
