NIOSH SHO Hazard Control study guide
NIOSH SHO Hazard Control · Work through your exam, one topic at a time.
The NIOSH Safety and Health Management (SH) Hazard Control credential targets the hazard-control knowledge that safety and health practitioners apply inside a functioning safety and health management system. It is built for industrial hygienists, safety specialists, occupational health nurses, supervisors with program responsibility, and consultants who must move from recognizing a hazard to selecting, implementing, and verifying the right control. The NIOSH SHO Hazard Control study guide has 6 sections and about 1,878 words.
01Hazard Identification and Anticipation
This domain tests whether you can find and predict workplace hazards before they become exposures or injuries. Expect questions on hazard categories, exposure routes, systematic identification methods, and design-stage anticipation rather than incident response.
313 words, about 2 min02Hierarchy of Controls and Control Selection
This domain tests control selection logic: why elimination and substitution rank above engineering controls, why administrative controls and PPE rank lower, and how to choose a feasible combination for each hazard. The NIOSH hierarchy is elimination, substitution, engineering controls, administrative controls, and PPE.
333 words, about 2 min03Engineering Controls and Ventilation
This domain tests whether you can specify, measure, and troubleshoot engineering controls, especially local exhaust ventilation (LEV). Expect hood design, airflow measurement, dilution versus capture, and maintenance issues.
327 words, about 2 min04Administrative Controls and Work Practices
This domain tests controls that change exposure time, procedures, and worker behavior. They are legitimate controls but rank below engineering controls because they depend on enforcement, training, and human performance.
318 words, about 2 min05Personal Protective Equipment (PPE)
This domain tests PPE as the last line of defense: hazard assessment, selection, fit, training, care, and limits. PPE does not remove the hazard and can fail silently.
297 words, about 1 min06Control Verification, Monitoring, and Program Evaluation
This domain tests whether controls actually work after installation and over time. Verification is not a one-time inspection; it includes exposure monitoring, ventilation checks, maintenance, recordkeeping, and program review.
