I am from Malaysia, and I am a qualified Safety & Health Officer. It is a prerequisite for some companies, especially in manufacturing, oil and gas, and construction companies (projects exceeding RM2 million), to have full-time safety officers employed. There are many projects you can write on, or alternatively, you can pick an industry, e.g., healthcare, and concentrate on the different types of safety, health, and welfare issues in that particular industry.
Hope this helps, and if you need any other information, please do write to me.
Regards,
Gowri
