ECS HS&E Test Practice Questions for Electricians: Free Guide
The ECS Health, Safety and Environmental (HS&E) assessment is the test most electricians need before an ECS card application. Here is what the test looks like, what it covers, how to revise and eight original practice questions to try.
Test format and pass mark
| Detail | Information |
|---|---|
| Question type | Multiple choice, closed book |
| Number of questions | 50 |
| Time allowed | 30 minutes |
| Pass mark | 43 out of 50 (86%) |
| Validity | A pass can be used for a card application or renewal for 2 years |
With seven mistakes allowed, you need steady knowledge across every topic rather than strength in just one or two.
What topics are covered?
Questions are drawn at random from a larger bank, across eleven topic areas. The number of questions from each topic in a typical assessment is shown below.
| Topic | Questions |
|---|---|
| Fire and emergency | 9 |
| General health and safety at work | 6 |
| Electrotechnical | 6 |
| Work at height | 5 |
| Manual handling operations | 4 |
| Personal protective equipment | 4 |
| Work equipment | 4 |
| Reporting accidents | 3 |
| Health and hygiene | 3 |
| Special site hazards | 3 |
| Environmental | 3 |
Fire and emergency is the biggest single topic, so give it extra attention.
How to revise
- Use the official ECS revision guide. ECS publishes a revision guide containing the question bank the assessment draws from, so it is the best place to start.
- Study by topic, not at random. Work through one topic at a time and test yourself afterwards.
- Understand the ‘why’. Knowing why an answer is correct (for example why CO₂ suits electrical fires) is easier to remember than memorising letters.
- Aim well above the pass mark. In practice, aim for consistently scoring 90% or more before you sit the real test.
- Revise little and often. Short daily sessions beat one long evening before the test.
