4 Fumigants & TICs Found in Containers Report from Rotterdam (T. Knol de Vos, 2002): 303 containers, screening for fumigants, low O2, ex-atm., 20% formed a risk; 5% were fumigants! Report from Hamburg (X.Baur, T.Ollesch, B.Poschadel, L.T. Budnik, S. Finger, G.Matz, 2006): 2100 containers, screening for fumigants and TICs, 17% formed a risk! New findings: less fumigants, more TICs (33%!)

5 Fumigants and their Thresholds (Germany) Fumigants TRGS-Value* AGW-Value** CH 3 Br, Methane,-bromo (Methyl bromide) PH 3, Phosphine (Hydrogen phosphide) CH 2 O, Formaldehyde SO 2 F 2, Sulfuryl fluoride (Vikane) HCN, Hydrogen cyanide (Prussic acid) NH 3, Ammonia 0,5ppm (TRGS 512) 0,01ppm (TRGS 512) 0,1ppm (TRGS 522) 1ppm (TRGS 512) 2ppm (TRGS 512) 10ppm (TRGS 522) - (mutagenic: suspicion) 0,1ppm - (carc. susp.) 2,4ppm 1,9ppm 20ppm CO, Carbon monoxide - 30ppm CCl 3 NO 2, Chloropicrin (Trichloronitromethane) - 0,1ppm *TRGS= Technical Regulations for Toxics **AGW= maximum allowable concentration (ex-mak) ppm= parts per million 1:10 6

6 Requirements grow quickly Broad Range: Number of compounds to be detected grow permanently. Detection of fumigants and other toxic gases, do not miss any hazardous condition Sensitivity: Toxic Gases at relevant concentrations: AGW or AEGL Selectivity: low rate of positive false results
