Components of a Safety Module

Educators: For information about accessing the solutions to the safety modules, please contact SAFEChE.

View the Chemical Safety Board video for the module

In each safety module, students will be asked to watch a video from the Chemical Safety Board about the incident focused on in the module. The link to the YouTube video is provided in every problem statement. A link to the incident report (if applicable) is also provided along with page numbers that may be relevant to the students’ understandings of the incident.

Fill out the Safety Analysis of the Incident

After students have watched the video, they are asked to fill out the Safety Analysis. Definitions of the different terms of the Safety Analysis are provided at the end of the document for reference. Some modules have “Module Specific” definitions for terms used in the video about the incident that students may have not heard yet.

Carry out a calculation related to the video and course.

Every Safety Module has a calculation portion. The course-specific calculations are related to the incident and help students to quantify what went wrong.

Fill out the chemical hazard assessment for the chemical of interest in the video

After the students have completed the relevant calculation, they are then asked to look up the chemical of interest from the incident and assess the chemical hazard. Information on how to access the NFPA labels for different chemicals are provided in the problem statement as well as in the Chemical Hazard Assessment tutorial.

Construct a BowTie diagram for the incident

In each Safety Module, students are asked to construct a BowTie diagram for the incident. Information about the different elements of the BowTie diagram are provided as to a link to the BowTie Diagram Tutorial.

A diagram starting with two separate potential problems, each leading to their own preventative actions, causing an initiating event for a hazard. That initiating event leads to two mitigating actions which each have their own consequence. The overall general shape is of a bow-tie.
