Managing combustible dust risks is a top-of-mind issue for many global manufacturers. Let’s say you’re aware of the dust hazards produced within your facilities and you know that you need to establish fire and explosion protection measures to protect life, 财产及业务连续性. 但, with multiple facilities in various locations, how do you identify consistent safeguards when each facility may have unique considerations?
当前基于危险的方法
Traditionally, there have been two main approaches to mitigating dust explosion hazards. The prescriptive approach is intended to be conservative and broadly applicable. It doesn’t take into account site-specific factors, 比如流程, ignition sources or occupant probability. 另一种方法, performance-based hazard protection, 关注所需的结果, rather than on how it should be done. This approach requires a detailed understanding of the process-operating conditions and protections. It's usually applied on a case-by-case basis.
应用基于风险的工具
Risk-based approaches to managing combustible dust have gradually gained ground. These methodologies expand the bounds of the code framework to gauge whether the likelihood and consequence of a combustible dust-related event (fire or explosion) compare favorably to acceptable risk levels. 换句话说, is the facility configured such that the risk of injury from your employee driving to work is the same as the risk of injury when she operates combustible dust handling equipment? Manufacturers can be confident in the answer by using customized 风险分析工具. 精密的模型, accounting for common variables like uptime, product throughput and existing protection measures, allows the owner to fine tune which protections will optimize risk-reduction measures. 在某些情况下, the analysis may also determine that no further safeguards are necessary in situations where risk is already low. 重要的是, a facility can demonstrate where their capital expenditures will yield the greatest risk reduction and which “protective” systems don’t meaningfully reduce risk.
Scalable 风险分析工具 are robust enough to capture variations for multiple locations, but concise enough to be deployed from a single database. They can help global corporations reduce exposures in line with industry risk thresholds, without having to meet ALL prescriptive measures of the NFPA standards.
Interested in applying this method to your enterprise? You may benefit from a risk-based model if your company can answer “yes” to these questions:
- Are your combustible dusts generally consistent and have you tested samples?
- Is your process information well documented?
- Do you have a high cost of prescriptive compliance?
- Does your industry, or specific equipment, have a relatively low loss history?
- Is there minor variability across your enterprise?
