Hazard Identification
- 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.
Emergency Response
- Access to availability of Emergency Response equipment.
