unprotected ear will be exposed to a peak sound pressure level of 140 dB ( C ). The use of hearing protection will be actively enforced . The buildings design will incorporate acoustic insulating materials wherever feasible .
● Vibration – workers exposure to vibration from hand and power tools and large equipment will be controlled through equipment selection , installation of vibration dampening pads and limiting the duration of exposure .
● Electrical – the plant will adopt the appropriate electrical safety measures for a facility of this nature to include marking all energised electrical devices with warning lights , locking-out and tagging-out all devices during service .
● Eye Hazards – the use of machine guards or splash shields and / or safety glasses or face shields ( as appropriate ) will be mandatory .
● Welding / Hot Work – the use of proper eye protection such as welder goggles and barrier screens will be mandatory . Hot work procedures will form an integral part of the Standard Operating Procedures for the plant .
● Industrial Vehicle Driving and Site Traffic – right-of-way , site speed limits etc ., will be clearly established to control site traffic . Drivers will undergo training and licensing as well as frequent basic medical surveillance .
Chemical Hazards
● Air Quality – air quality will be regularly monitored consistent with the IFC Guidelines Section 2
● Fire and Explosions – prevention and control strategies for fires and explosions are outlined in IFC Guidelines Section 4.4
● Asbestos – Agrium have confirmed that there is no residual asbestos containing materials in KNO plants 4 , 5 and 6 . The Functional Design Specification for the EPC Contractor prohibits the use of asbestos for the relocated plant construction .
Biological Hazards
● Work processes , engineering and administrative controls will be designed , maintained , and operated to avoid or minimise the release of biological agents into the work environment .
● Measures to eliminate and control hazards from known and suspected biological agents at workplaces will be maintained in close co-operation with local health authorities .
Radiological Hazards
● Workplaces with occupational and natural exposure to ionizing radiation will be established and operated in accordance with the appropriate international standards and guidelines .
● Exposure to non-ionizing radiation ( such as static magnetic fields , static electric fields , radio frequency , microwave radiation , light and near-infrared radiation and ultraviolet radiation ) will be controlled to internally recommended limits .
Communication Systems
● Alarm bells , visual alarms will be used to alert workers and emergency services to an emergency
● Alarm and warning systems will be tested at least annually .
● Plans and measures will be implemented to communicate a potential emergency to the community if the community is at risk from such potential emergency .
● Emergency information will be communicated to the media through trained local spokesperson and via formal press releases with accurate information and Construction Phase Site Rules to be completed prior to Construction Start – this document will be issued to and adhered to by all contractors .
