Occupational Safety and Health (OSH)

Objectives

The topics included in this unit should afford FCT-NOVA students the fundamental knowledge and skills to deal with occupational safety and health (OSH) and its management; the contents are interrelated with other matters of their curricula.

 At the end of the semester, students should have gained fundamental competencies and skills to:

- participate in OSH Management

- identify common workplace hazards

- carry out preliminary risk assessments and prevent risks commonly present in most industrial workplaces

- communicate risk, and discuss risk prevention with the company''s local OSH managers (OSH officers)

Teaching method

1 Theoretical component 

At the beginning of each topic, an oral presentation is given using slides (PowerPoint). The students are encouraged to intervene and interact with the lecturer, with a view to assessing their knowledge in other associated matters. This way, the lecturer has the possibility to make a brief review of other issues that need clarification, in order to facilitate communication and understanding.

2 Practical components and laboratory sessions

In view of the very practical nature of this course, real examples and case-studies are analysed (as far as reasonably possible,). To this effect, photos and videos are frequently used. 

In addition, the following activities are also carried out:

-   Solving practical cases and calculations. Discussion of results (accident statistics, accident rates, chemical contamination levels, and their respective Confidence Intervals, noise levels, etc).

-   Team-work (groups of around 3), in which students have to carry out a search and analysis of National and European OSH Regulations. Each group has to make an oral presentation on a specific topic for the whole class (PowerPoint). This oral presentation is designed not only to assess students’ ability to analyze and synthesize legal requirements but also to extend the knowledge they receive within the lectures. It allows disseminating OSH legislation.

-  Use and demonstration of PPE (Personal Protective Equipment); this is done through the existing set of equipment in the LAB. Legal aspects of PPE. Safety signs: same as previous.

-   Noise measurement – assessment of noise exposure using existing equipment (sound level meters). Protection and prevention measures. Discussion of results (at the end, students are required to deliver a summary report with results and main conclusions).

-  Level of illumination – measurement and evaluation parameters. Use of lux meters. Calculation and assessment of the illumination requirements of a workplace (work room). Analysis and discussion of the results (at the end, students are required to deliver a summary report with results and main conclusions).   

For registered students, information on the course and teaching materials are available online within the CLIP system.

Evaluation method

Evaluation is based on 3 elements (graded 0-20), as follows.

> 1 GROUP ASSIGNEMENT (GA) (20% weight on final classification) - specific topic per group, with the delivery of a PowerPoint (oral presentations this year are made via Zoom due to Covid-19 restrictions).

This first assignment is used to decide whether the student gains access to the final exam (minimum score is 10).
 

> 2 INDIVIDUAL TESTS (T) (80% weight on final classification, 40% each test) (average min score is 9.5). If necessary, these individual tests will be carried out online (and adapted for such a modality). 

Students failing to "pass" in the two tests, may try again at the two Examination periods (Jun & Jul) 

Students wishing to improve their grade may attend the second Examination period (JUL)

   FINAL GRADE (average)=

[20%GA + 40%T1 + 40%T2]
