Objectives

OSH (Occupational Safety and Health): The topics included in this unit should afford FCT-UNL 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.

Skills: At the end of the semester, students should have gained fundamental skills concerning OSH Management, including the identification, the broad assessment and prevention of hazards and risks commonly present in most workplaces.

Prerequisites

None in particular.

Subject matter

1. Introduction Safety Management: Occupational Safety and Health (OSH) management systems. Legal aspects.Introduction to the concepts of hazard, risk and risk acceptability.The ALARP principle in risk management.
2. Occupational accidents and their prevention: Accident causation models, statistical indices more commonly used; performance indicators for OSH.
3. Fire and Explosion: Explosion and fire limits. Flammable substances and their classification. Fire and explosion risks and their assessment. Fire prevention and protection strategies. Firefighting: main systems and equipment.
4. Occupational Health and Industrial Hygiene: Chemical hazards. Control of Substances Hazardous to Health (COSHH). Occupational noise. Exposure to vibrations. Illumination in the workplace. Thermal environment.
5. Occupational Safety: Safety Signs. Personal Protective Equipment. Storage of hazardous substances. Electrical hazards.

Teaching method

Teaching methods 

1- Theoretical lectures In these, an oral presentation is given using slides (data show), and sometimes the black-board. The students are encouraged to intervene and interact with the lecturer, with a view to assess 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 lectures and laboratory sessions

In view of the very practical nature of this course and as far as reasonably possible, real examples and case-studies are analysed. 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 indices, chemical contamination level, noise level and exposure, etc).

-   Team-work concerning the search and analysis of national regulations. Each group has to make a presentation on a specific topic for the whole class.

-  Use and demonstration of PPE (Personal Protective Equipment); this is done through the existing set of equipment in the LAB. Legal aspects.   -Safetysigns. Same as above.

-   Noise measurement – assessment of noise exposure using existing equipment (level sound meters). Protection and prevention measures. Discussion of results. For this lab work students are required to present a written report (individual work, presented as a "conference paper").

-  Level of illumination. Lab work: measurement and evaluation parameters. Use of illumination meters. Analysis and discussion of the results.   -  Hazard identification and Risk assessment methods. Examples of application to real cases. At the end, the students should be able to apply the acquired knowledge and propose adequate prevention and protection measures.

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

Evaluation method

Continuous evaluation system, based on 3 elements with classification (grade 0-20) + 1 element requiring only "presence" of the student in a Lab session in which he/she should carry out a Lab Work.

1 GROUP ASSIGNEMENT (GA) (20% weight on final classification)

1 group work, with individual presentation - specific topic per group - oral presentation and discussion (covers relevant matters of the national and EU OSH Regulations and Law).

This first assignment is used to decide whether (or not) the student gains access to the final exam (minimum score is 9). Once achieved, this component is valid within one academic year, with the same grade and the same weight on the final score.

 2 INDIVIDUAL TESTS (T) (80% weight on final classification, 40% each test)

2 individual tests (maximum 1h, within the regular timetable of theoretical sessions)

PS: for individual tests and exams, students can only use scientific calculators. Grphic machines and Internet devices are not allowed.  

PRESENCE AND PARTICIPATION IN ONE LAB WORK

At least ONE Lab Work must be made by each student (assessment of Noise or Illumination of workplaces). Evaluation is 0/1, i.e., it does not enter the final average, but the work is compulsory. Each student is required to make the measurements, calculations and write a summary conclusion during the Lab session. He /She needs to hand out a draft manuscript with the results at the end of the session.

Only the final grade is rounded.

FINAL GRADE (average)= [20% GA + 40% T1 + 40% T2] x (0/1) Lab
