Description
Abstract
Workplace Safety and Health has always been one of the top concern of Ministry of Manpower. To better manage MSH, MOM established Workplace Safety and Health (WSH) Council on 1 Apr 2008. WSH Concil coordinates with MOM to conduct research on workplace safety and health performance in Singapore. The WSH Institute conducts quality applied research and provides evidence-based information to Ministry of Manpower, WSH Council and industry stakeholders to improve WSH practices in Singapore. The data used were collated from incident reports made by employers, occupiers and medical practitioners.
This Assignment will generate analysis utilizing WSHI work place injuries data in year 2014 to gain insights of workplace safety and health situation in 2014.
Theme of Interest
In order to be more efficient in improving workplace safety and health situation, it is essential to find out the 'Vulnerable groups' and characteristics tied with different groups. Therefore MOM can provide customized plans in order to prevent the happens of injuries and react to injuries faster and smarter.
This assignment aims to find out the major vulnerable groups and peak period of workplace injury cases to facilitate MOM's customization of planning and policy-making.
Research Question
- What characteristics do the 'more vulnerable' groups have?
- What characteristics do the 'high injury rate' campanies have?
- When is the peak period of accidents?
- Does overtime play a important role in the causing factors of injuries?

- Victim's Age
- Victim's Gender
