Identify chemicals that are incompatible if mixed.
Identify places/opportunities when incompatible chemicals may be wrongly interacted and manage their confinements.
Avoid using the incompatible chemicals, if possible, in the process as part of Inherently Safer Design. Use alternate compatible chemicals.
Maintain chemicals and materials interaction matrix.
Human Factors – Design of Chemical Transfer Equipment
Isolate physically or using distance to separate fill lines to lower risk of incorrect connections.
Use hose couplings and fill line connections with uniquely shaped and color-coded fittings for each chemical.
Identify each chemical by unique labelling and identification tag.
Automation and Remote Shutdown
Install or configure interlocks and mitigation measures to maintain safe operations during chemical unloading activities.
Install fume detection, extraction and destruction system in chemical warehouse for mitigating event.
Facility Siting and Design of Occupied Building
Evaluate building design and ventilation systems near chemical unloading stations and chemical storages to protect the occupants in the event of spill or chemical reaction.
Segregation of Storages
Separate locations for storing incompatible materials.
Dykes or bunds around liquid chemicals storages.
Segregation of Collection and Effluent Pits
Maintain separate collection pits for draining of chemicals that may interact and have hazardous consequences.
Examine the draining systems for avoiding possible mixing of incompatible chemicals.
