Private Sidings Ammonia Loading Sodium Cyanide
Liquid Sodium Cyanide - Isotainers 18kL Isotainer
Liquid Sodium Cyanide - Isotainers 22kL Isotainer
Liquid Sodium Cyanide – Loading The loading installation includes the following components: • Rail siding for standard gauge wagons, main line and shunt line. • 4 x Loading platforms to provide access to the top of the isotainers. • Bunded rail loading area, drainage to the tank farm sump. • Designed to load 4 x 22kL Isotainers simultaneously through articulated loading arms fitted with Kamvalokcouplers @ At 400m3/hr. • Amount to be loaded is controlled by mass measuring equipment. • Displaced air from the containers is vented to atmosphere. • RFID feedback to the DCS for pre-determined fill set points.
Potential Hazards associated with NaCN filling • Loading Hose failure • Overfilling of isotainer • Loss of containment from despatch pipework • Movement of isotainer/wagons during loading • Cyanide exposure during coupling/decoupling
Controls for Liquid Sodium Cyanide Loading • Emergency response plans • Trained and competent loading operators in PPE • High level switch in vent lines, mass cut-off logic, volumetric cut-off logic • Preventative maintenance, including trip checks • Shunting procedure and high rail vehicle • ‘No motion’ proximity switch to detect uncontrolled rail movement and cut off fill • Isotainer inspection activities – planned inspections
PotentialHazards associated with Rail • Person crushed/caught between wagons • Collision when shunting within private rail siding • Collision with fouled vehicles • Out of control movement • Loss of Containment during shunting operations within private rail siding
Controls for Rail • Shunting procedure including 3 step protection in danger zone • Line of sight of operator piloted by spotter on radio • Very low shunting speeds (7km/hr) • Track maintenance and inspections • Use of train brake for all movements, emergency air dump handle fitted to hi-rail shunt vehicle • Train operators aware of incompatible materials and separation distances
44t Anhydrous Ammonia Bullets Filling Pressure 500kPa @ approx 800 l/min
PotentialHazards associated with Ammonia Loading • High pressure in loading arm • High level in Isotainer • Ammonia release from loading arm • Movement of Isotainer during filling • Ammonia release causing chemical asphyxiation or burns
Controls for Ammonia Loading Facility • High pressure trip • Gas Detection automatic shutdown • High level trip • Local ESD with water curtain sprays • Low Pressure trip • Gas and liquid arm proximity switched • Visual checks, including one by second operator • Trained and Competent personnel with PPE • Use of thermal camera to determine returned level
Emergency Response Support • CSBP provides Emergency Response and technical support for all its products whether on road or rail, on or offsite. • Dedicated Incident Management Team, Emergency Response Team • MoU with BIS (Brambles Industrial Services) for support nearer to Kalgoorlie
