Principles that guide the identification and practical treatment of chemical hazards in today’s society.
Do you want to know what defines a chemical hazard, the effects of these hazards on our health, legislation governing their handling and transportation and how to deal with incidents involving chemicals? Then this is the paper for you! It will be of particular value to employees who may face situations where they have to deal with chemicals or the consequence of chemical use (public bodies, legal firms, environment officers, emergency services etc). It is designed to enable graduates or individuals with appropriate experience in the management of hazards to develop a critical approach to the principles that guide the identification, classification and treatment of chemical hazards in a modern society.

Hazard Assessment and Management must either be a graduate or holder of a professional
qualification requiring at least three years' tertiary-level study or have alternative
qualifications or experience acceptable to the approval of the Board, which will require
evidence of ability to undertake advanced academic study. A minimum background in
chemical knowledge to Year 13 or First Year University level is assumed.

- Paper Structure
The paper has seven modules:
- Review of national and international chemical incidents, with a focus on Parnell and ICI incidents as a basis for showing the types of problems that have occurred and the need for new regulations and procedures
- Material safety data sheets: contents, usage and preparation and where to find them
- Chemical hazards: definition, energy changes, reaction rates, catalysts, flammability and combustibility, fires and the fire tetrahedron
- Toxicology: physiological basis; LD50 (median lethal dose); how poisons get into the body, and what they do; psychological stress; types of poison (chronic, corrosive, etc)
- Legislation: Dangerous Goods Act, Health and Safety in Employment Act, the HSNO Legislation, administrative procedures, health and safety, storage of chemicals, UN labelling system for hazardous materials, workplace exposure standards
- Management of hazardous materials: safe handling and disposal, transportation, workplace and emergency services; HSTLC's National Poisons Centre and the emergency services - Fire Service, Police, local bodies - and how hospitals function in an emergency
- Special topic with corresponding case study of a chemical
There are two pieces of assessment to finish the paper. The first is to write a summary of a report completed on an incident that has occurred, and the second is a case study which involves writing your own report on an incident.
- Teaching Arrangements
This Distance Learning paper is taught remotely.
Self-learning is the pedagogical basis for the paper, with students being directed to material rather than detailed lecture notes being provided. The paper is web-based, allowing individuals to learn and assimilate at their own pace. Teaching materials, assignments and assessments are mostly in a web-based format using the University of Otago's Blackboard platform. The paper is taught over a 20-week period.
There is no final examination. The final mark is based on assessments during the paper. There is no on-site requirement for this paper.
- Three assignments (60%)
- Summary report (15%)
- Case study (25%)
The summary report requires students to summarise an existing report completed on an incident. The case study involves students writing their own report on an incident.
Assignment due dates will be confirmed at the start of the paper but are normally as follows:
- Assignment 1 due mid-April
- Assignment 2 due mid-May
- Assignment 3 due mid-June
- Summary report due early July
- Case study due late July
- There are no textbooks recommended for this paper. Most of the material will be accessed from Blackboard. This includes instructions, announcements, text files, exercises and assignments.
- Graduate Attributes Emphasised
- Global perspective, Scholarship, Communication, Critical thinking, Self-motivation.

- Learning Outcomes
- Students who successfully complete the paper will
- Learn of the important properties of chemicals that determine their hazard classification and the concepts, legislative principles and societal issues arising from the use of chemicals and management of chemical hazards
- Develop the ability to recognise the consequences of chemical hazards, to access and extract relevant information from databases, and to propose alternate strategies for storing and handling hazards and dealing with the public
- Learn to encourage legal, safety and public awareness attitudes to the handling of chemical hazards
- Develop a deeper scientific understanding of what constitutes a hazard and of the interactions of a particular hazard with other hazards and the environment and be better prepared to recognise and implement various strategies to resolve risk
- Be able to place in a modern context the legal, ethical and social concerns arising from the use of chemicals
