With the strong efforts of the WG on Combustible Dust since 2017, the new Singapore Standard on Code of practice for handling, storage and processing of combustible dust (SS 667: 2020) was published in Mar 2021 with its webinar launch on 19 May 2021.
The SS 667 provides a comprehensive procedure on the handling, storage and processing of combustible dust to prevent and mitigate fires and dust explosions in facilities handling such materials. It is designed to aid users in the assessment of dust fire and explosion hazards and the mitigation of those hazards through facility design, equipment/process control measures, elimination of ignition sources and minimising damage.
The webinar gathered strong interest from the industry and was attended by over 210 participants from more than 70 enterprises. The webinar provided a deep dive into key sections of the new SS 667, including the importance of material hazard identification (MHI). If the material is deemed to be combustible or explosive, a dust hazard analysis (DHA) would then play a crucial role in ensuring the safety of the work environment.
With the sharing of combustibility and explosivity tests, the participants gained useful information on the possible methods to be used to determine the relevant properties of their materials.
Having developed the maximum allowable quantities (MAQ) in SS 667, the presenters also showcased the possible scenarios which would enable the industry to store specific combustible dust above ground level. This was made possible with the requirements and guidance provided in the newly published SS 667.
In order to provide further guidance, examples on DHA and determination of threshold limits of dust were also presented during the webinar.
