Bulk Solids Handling & Processing Innovations
The deadline for completing a DHA was September 7, 2020. This legal requirement is enforced by OSHA. If you have not yet completed a DHA, you are liable to fines or sanctions from OSHA and other regulatory bodies.
This article summarises what is needed for a DHA, where explosion protection fits into it and how Oseco-Elfab can help you maintain compliance.
NFPA 652 defines a Dust Hazard Analysis (DHA) as ‘a systematic review to identify and evaluate the potential fire, flash fire or explosion hazards associated with the presence of one or more combustible particulate solids in a process or facility.’ It is only the review must be completed by September 7. Any recommendations coming out of it can be completed after that date. A common recommendation is to verify that existing explosion panels are designed per NFPA 68.
NFPA 68 is the US standard on explosion protection by deflagration venting. It covers the design, location, installation, maintenance, and use of devices and systems that vent the combustion gases and pressures resulting from a deflagration within an enclosure so that structural and mechanical damage is minimized. The main requirements relate to documentation, inspection, maintenance, training and record-keeping:
