ENHS 335: Occupational Health and Industrial Hygiene

ENHS 335 at the University of Maryland Global Campus (UMGC) investigates work-related impacts on human health and the environment.

UMGC lists ENHS 310 as the prerequisite. The goal is to anticipate, recognize, evaluate, control and confirm the effectiveness of controls for occupational health hazards through industrial and occupational hygiene practice.

The course tests both science and judgment. Students must interpret exposure information, think about who is vulnerable, and choose controls that suit the hazard. The "confirm" step, proving that controls actually work, is often forgotten.

What ENHS 335 Covers

Key Concepts Explained

Anticipate, Recognize, Evaluate, Control, Confirm

This cycle structures the discipline. Anticipate hazards before they occur, recognize them on site, evaluate exposure against criteria, apply controls and verify results with follow-up monitoring.

Hierarchy of Controls

Prefer elimination and substitution, then engineering controls such as ventilation, then administrative controls and personal protective equipment. Explain why a chosen control is feasible and effective.

Susceptible Workers and Privacy

Some workers are more vulnerable, for instance those with certain conditions or who are pregnant. Controls and return-to-work plans must protect them while respecting confidentiality of health information.

Typical Assignments and How to Approach Them

Where Students Get Stuck

• Skipping the confirm step. Explain how you will verify the control.
• Units and limits. Define the exposure criterion you use.
• Over-reliance on PPE. Show why higher controls were not feasible if you choose it.
• Privacy. Show awareness of confidentiality in return-to-work cases.

Study Tips for ENHS 335

• Review your ENHS 310 notes on routes and effects.
• Make a checklist for each stage of the cycle.
• Practice explaining ventilation types in plain language.
• Use authoritative guidance and peer-reviewed sources and cite them.

Cycle Worksheet

Working Through Indoor Environmental Quality and Ventilation

Two catalog topics, indoor environmental quality and ventilation, often appear together in case studies of "sick building" complaints.

Return to Work and Susceptible Workers

Return-to-work programs aim to bring workers back safely after injury or illness, with suitable duties and communication among the worker, employer and health provider. For susceptible workers, show how you would adjust exposure controls while avoiding discrimination and protecting confidential health information.

Common Mistakes to Fix Before You Submit

• Recommending respirators without considering ventilation or substitution.
• Reporting exposure results without the limit they were compared against.
• Skipping a plan to confirm that controls work.
• Putting identifiable health information in a return-to-work example.

A quick check against the five stages of the cycle will catch most of these before a marker does.

Reading a Prompt and Planning Your Time

If a prompt provides exposure data, begin by stating what the numbers represent: a sample, an average over a work period or a peak. Then name the criterion used for comparison and say whether the result is above or below it. Only after that should you discuss controls.

If no data are given, say what data you would collect and why. Naming the sampling approach shows that you understand the evaluate stage even without numbers.

How We Help with ENHS 335

Send the prompt, rubric, data and scenario. We can provide a custom analysis, explain the cycle, or review your draft, with sources cited.
