The Integrated Management System in POLICE Chemical Company S.A. includes the Quality Management System ISO 9001:2000 (confirmed with the TÜV NORD POLSKA certificate has been functioning in POLICE Chemical Company S.A. since 23 January 2004), the Environmental Management System ISO 14001:2004 and the Occupational Health and Safety Management System PN-N 18001:2004 (compliant with the International Standard OHSAS 18001). In case of iron (II) sulphate, due to the possibility of its application as addition for feed, the Hazard Analysis and Critical Control Points system (HACCP) and the Food Safety Management System according to EN ISO 22000:2005 have been implemented.
Iron (II) sulphate is transported by flexible truck containers with a capacity between 500 kg and 1000 kg or in bulk (by truck cisterns, covered road transport or railway transport). Flexible containers with FESPOL should be stored in clean and dry storage buildings. Products supplied in bulk should be stored in silos (FESPOL 20 and FESPOL 28)or in clean and dry storage buildings (FESPOL 17).
