| 6.1 | Intentional transmitters |
This may include radios, communication transmitters, RF ID scanners, WiFi and Bluetooth.
| (i) | Select the equipment. |
| (ii) | Obtain information about the equipment i.e. supplier, manufacturer, model, type specification. |
| (iii) | Confirm ICASA certification. |
| (iv) | Obtain the Effective Radiated Power (ERP) from ICASA certificate. |
| (v) | Using the ERP and with the aid of the graph in Figure 3 above read off the exclusion distance in m for the equipment. |
| (vi) | Repeat the above procedure for all the other intentional transmitting equipment. |
| 6.2 | Non-intentional transmitters |
This may include equipment installed or used in the explosives production facilities and may include all the hard-wired equipment i.e. scales, programmable logic control systems, distributed control system, process variable transmitters, various sensors, proximately switches, laser devices, cameras.
| (i) | Select the equipment. |
| (ii) | Confirm whether the equipment has a mark, if so, continue with step (iii), if not, then proceed to step (vi). |
| (iii) | Obtain a test report of the equipment from the supplier i.e. model, type, specification. |
| (iv) | Calculate the ERP from the test report and with the aid of the graph of Figure 3 read of the exclusion distance in metres for the equipment. |
| (v) | Repeat the above procedure for all the other non -intentional transmitting equipment. |
| (vi) | Arrange for testing of equipment for RF emissions & immunity to be carried out by an EMC testing laboratory according to Government Gazette 39182 of September 2015. |
| (vii) | Receive from the test laboratory a report showing the Immunity (V/m) and the Effective Radiated Power (dBm or mW). |
| (viii) | Using the ERP and with the aid of the graph in Figure 3 above read off the exclusion distance in m for the equipment. |
| (ix) | Repeat the above procedure for all the other non -intentional transmitting equipment. |
