Report on Thermal and Combustion Decomposition Products

Project Overview
Sutok was engaged to calculate the decomposition products of sodium dichloroisocyanurate (NaDCC) resulting from heating or fire. The assessed process concerned on-site storage of the substance to produce disinfection tablets.
A detergents manufacturer needed to add this substance to its Hazardous Substances Permit and had experienced months of delay prior to contacting Sutok.
Approach and Deliverables
Document review and data validation: We examined all materials and information provided by the plant.
Safety recommendations: We presented practical guidance to ensure safe operations, including separation distances and operating procedures.
Risk assessment: We evaluated site-specific conditions and potential incident scenarios to quantify and reduce risk.
Risk Assessment Scope
We assessed all relevant, case-specific parameters, including:
Site and surroundings: Facility layout, neighboring uses, and sensitive receptors
Meteorology: Local wind patterns and atmospheric stability considerations
Materials inventory: Co-located substances that could react with NaDCC, with emphasis on hazardous materials and incompatibilities
Scenario Analysis
To characterize accident likelihood and impact, we analyzed multiple credible in order to:
Identify initiating events and escalation factors.
Determine appropriate mitigation and prevention measures.
Define operational and emergency controls that reduce overall risk.
Compliance and Standards
All process checks and scenario evaluations were performed to a high technical standard, accounting for environmental factors, plausible extreme conditions, and in alignment with the Ministry of Environmental Protection (MoEP) regulations.
Outcome
The request to add sodium dichloroisocyanurate to the plant’s Hazardous Substances Permit was approved immediately following submission of Sutok’s report.
About Sutok
Sutok specializes in environmental consulting and provides end-to-end support throughout the hazardous substances permitting process, including close coordination with the relevant regulatory authorities.
