ENHS 315 at the University of Maryland Global Campus (UMGC) examines the general concepts of risk assessment as applied to environmental health and safety practice.
The catalog aim is to incorporate best practices for risk assessment, analysis and mitigation recommendations for effective management of change. The ENHS 495 capstone lists it as a prerequisite.
Students find that the course requires judgment as well as method. You must characterize a hazard, estimate how likely and how serious harm could be, and justify recommendations. Unsupported ratings are the most common reason for lost marks.

Key Concepts Explained
Hazard, Exposure and Risk
A hazard is a source of potential harm. Risk combines the likelihood of harm with its consequence, and in many contexts depends on exposure. No exposure means no risk, even from a severe hazard.
Example: A sealed drum of corrosive liquid is a hazard. If a forklift route passes the drum and spills have occurred before, likelihood rises. If a spill would reach workers or a drain, consequence rises. Rating each separately and giving a reason produces a defensible risk level.
Qualitative and Quantitative Methods
Qualitative matrices rank risks as low, medium or high. Quantitative methods use numbers and data. Say which you used, why, and what its limits are.
Mitigation and Management of Change
Recommendations should follow a clear logic, usually preferring elimination or substitution before engineering controls, administrative controls and personal protective equipment. Explain how a proposed change itself might introduce new risk.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Risk assessment report | Method and judgment | Define scope, identify hazards, rate risk, recommend controls |
| Risk communication task | Risk perception | Write for a non-expert audience and address their concerns |
| Tool or database review | Information skills | Compare what each source offers and its limits |
| Risk transfer discussion | Options | Weigh costs, coverage and residual risk |
Where Students Get Stuck
- Ratings with no reason. Give evidence for every likelihood and severity score.
- Scope creep. Define what is in and out of the assessment.
- Controls that do not match the risk. Link each control to a specific cause.
- Ignoring perception. Include how stakeholders see the risk.
Study Tips for ENHS 315
- Use one consistent matrix and explain its scales at the start.
- Practice on short scenarios before longer reports.
- Keep a list of public databases and what each can tell you.
- Note residual risk after controls, because it shows complete thinking.
A Risk Register Layout
| Column | What to enter |
|---|---|
| Hazard | The named source of harm |
| Likelihood and severity | A rating for each, with the reason |
| Control | The specific action proposed |
| Residual risk | The rating after the control |
A Worked Risk Assessment Walkthrough
Consider a facility that stores a flammable solvent near a loading dock. Here is how a short assessment might be structured.
| Step | Example content |
|---|---|
| Scope | Storage area and dock, normal operations, excluding off-site transport |
| Hazard | Flammable vapor and ignition sources near vehicles |
| Likelihood | Medium, because spills have occurred and vehicles pass daily |
| Severity | High, because a fire could injure several workers |
| Risk level | High, from the combination, as defined by the matrix you state |
| Controls | Relocate storage, add spill containment, restrict ignition sources |
| Residual risk | Medium after controls, with monitoring and review |
Handling Risk Perception
Two groups can look at the same numbers and disagree. Workers may fear rare, dramatic events more than common, minor ones. Explain how you would listen to concerns, share data honestly and adjust communication, without dismissing perception as irrational.
Common Mistakes to Fix Before You Submit
- Using a matrix without defining what low, medium and high mean.
- Recommending controls without re-rating the risk afterwards.
- Forgetting ecological receptors when the scenario includes them.
- Assuming risk perception equals risk magnitude.
Reading a Prompt and Planning Your Time
Risk assessment prompts often ask for a method as well as a result. Decide early whether you are producing a qualitative rating or a numeric estimate, and explain the choice in the first paragraph.
Spend the first third of your time defining scope and hazards, the middle third rating and justifying, and the last third on recommendations and residual risk. Students who rate quickly and leave recommendations to the end usually run out of time for the part that carries most weight.
How We Help with ENHS 315
Send your prompt, rubric, scenario data and any template your instructor provides. We can produce a model risk assessment, explain method choices, or give feedback on your draft, with sources cited.
The help is for study and reference. It is not professional safety advice, not for submission as your own work, and no grade is promised.
