Madam, I thank the Member for his suggestion and I appreciate why he raises this. But I do want to point out that, in a sense, almost anything that is potentially combustible can pose a danger. It just depends on the level of concentration. Therefore, if we were to go about listing them, I think it will be a very long list. So, I think we have to go on a risk-based approach to this. Clearly, the highly combustible substances are very tightly regulated. Beyond that, those substances which are of relatively low combustible property, I think we should let the authorities look at this, especially the SCDF, and make the assessment. It may pertain to how it is used or additional restrictions on thresholds, in terms of how much quantities are brought into a particular event or an activity. So, let the SCDF and SPF make their assessment and, if there is a need for further finetuning of our regulations, we will do so. But we are not, at this stage, contemplating expanding the coverage in a manner that covers all combustible materials because that would be quite impractical.
