| Summary and Challenges |
- Carrying out work in confined spaces is inevitable for the government, such as the works at the grey water collection tanks and valve chambers at sea water pump house. To effectively reduce the risk of working in confined spaces, some monitoring measures shall be applied on the contractors who are entering the confined spaces, like the requirement of PPE and the strict adhesion to the laid down procedures. Besides, to lower the danger caused by the working environment in confined spaces is another key.
- As such, regular air quality checking is required. Furthermore, a robotic system is highly recommended to be applied for replacing the work of human resources, like the work of cleansing, removal, lifting and so on. The chance of causing human error can be therefore reduced to a minimum.
