CIH - Certified Industrial Hygienist IH Program Management Questions and Answers — Questions and Answers
Question 1: An industrial hygienist is asked by management to re-sample a work area for a specific chemical after initial results indicated an exposure above the Permissible Exposure Limit (PEL). Management suggests waiting for a day when production is scheduled to be significantly lower. According to the AIHA Code of Ethics, what is the IH's primary responsibility?
- Follow the management directive to maintain a good working relationship and ensure future access for sampling.
- Resample on the lower production day but report the average of the two different sampling events.
- Refuse to conduct the sampling and report the company to the appropriate regulatory agency immediately.
- Uphold professional integrity by advising management that sampling must be representative of typical employee exposures to be valid. (Correct answer)
Correct answer: Uphold professional integrity by advising management that sampling must be representative of typical employee exposures to be valid.
The AIHA Code of Ethics requires industrial hygienists to practice their profession following recognized scientific principles and to act responsibly to uphold the integrity of the profession. Sampling during an uncharacteristically low production day would not be representative of typical exposures and would compromise professional judgment. The correct action is to counsel management on the need for scientifically valid, representative sampling.
Question 2: Which of the following is considered the foundational first step when establishing a comprehensive industrial hygiene program at a new manufacturing facility?
- Conducting a baseline qualitative exposure assessment to anticipate and recognize potential hazards. (Correct answer)
- Purchasing and distributing personal protective equipment for all production employees.
- Performing quantitative air sampling for all chemicals listed on Safety Data Sheets.
- Developing detailed engineering control plans for all manufacturing processes.
Correct answer: Conducting a baseline qualitative exposure assessment to anticipate and recognize potential hazards.
The first principle of industrial hygiene is anticipation and recognition of hazards. Before any controls can be implemented or quantitative measurements taken, a thorough qualitative assessment must be performed to identify potential chemical, physical, biological, and ergonomic hazards associated with the facility's processes and materials. This forms the basis for all subsequent program activities.
Question 3: The "Plan-Do-Check-Act" (PDCA) cycle is a management method used for continuous improvement. In the context of managing an industrial hygiene program, which of the following activities best represents the "Check" phase?
- Implementing a newly designed local exhaust ventilation system for a welding station.
- Conducting annual audiometric testing and analyzing exposure data trends for the hearing conservation program. (Correct answer)
- Developing a sampling strategy for a newly introduced solvent in the facility.
- Training employees on the proper use and maintenance of their assigned respirators.
Correct answer: Conducting annual audiometric testing and analyzing exposure data trends for the hearing conservation program.
The "Check" phase of the PDCA cycle involves monitoring, measuring, and analyzing the results of the actions taken in the "Do" phase to see if the desired outcomes were achieved. Conducting audiograms and analyzing data trends are monitoring activities that check the performance and effectiveness of the hearing conservation program against its objectives. The other options represent "Do" (implementing, training) and "Plan" (developing a strategy) phases.
Question 4: An industrial hygienist completes an exposure assessment for lead and finds that while all 8-hour TWA results are below the OSHA PEL, several are above the Action Level. What is the most appropriate next step regarding risk communication?
- Notify the affected employees in writing of their individual results within the mandated timeframe. (Correct answer)
- Inform only the management team, as no PELs were exceeded and no immediate action is required.
- Wait until the next round of sampling to see if a trend develops before communicating results.
- Post a single summary of the area results in a common area without notifying employees individually.
Correct answer: Notify the affected employees in writing of their individual results within the mandated timeframe.
The OSHA Lead Standard (29 CFR 1910.1025) explicitly requires employers to notify each employee in writing of their exposure monitoring results within a specific timeframe (e.g., 15 working days) after receiving them. This requirement applies regardless of whether the PEL is exceeded, and it is crucial when exposures meet or exceed the Action Level, as this triggers other requirements like medical surveillance.
Question 5: According to OSHA's standard on Access to Employee Exposure and Medical Records (29 CFR 1910.1020), which of the following records must be retained for the duration of employment plus 30 years?
- Calibration logs for direct-reading instruments.
- An employee's personal medical records related to workplace exposures. (Correct answer)
- Minutes from monthly safety committee meetings.
- Annual fit-test records for an employee's respirator.
Correct answer: An employee's personal medical records related to workplace exposures.
OSHA's 29 CFR 1910.1020(d)(1)(i) requires that each employee's medical records be preserved and maintained for at least the duration of employment plus thirty (30) years. Employee exposure records must be kept for 30 years, but medical records have the additional requirement of covering the full duration of employment. The other records listed generally have shorter retention requirements.
Question 6: When auditing a facility's Hearing Conservation Program, which of the following findings would represent the MOST significant programmatic failure?
- The written program has not been formally reviewed by management in the last two years.
- Training records are missing for approximately 10% of the enrolled employees.
- Baseline audiograms are not being established for new employees exposed at or above the action level. (Correct answer)
- A few employees were observed wearing their hearing protection incorrectly in a high-noise area.
Correct answer: Baseline audiograms are not being established for new employees exposed at or above the action level.
Failure to establish a valid baseline audiogram for new employees exposed at or above the 85 dBA TWA action level is a fundamental failure of a hearing conservation program. The baseline is the reference against which all future annual audiograms are compared to detect a Standard Threshold Shift (STS). Without a baseline, the entire medical surveillance aspect of the program is ineffective for tracking occupational hearing loss. The other options are compliance issues but do not invalidate the core function of the program to the same degree.
