transport of dangerous goods and risk management - Kirilo Savić

TRANSPORT OF DANGEROUS GOODS AND RISK MANAGEMENT 75Labelling of dangerous loads in different means of transport (vehicles)Labelling of dangerous loads in different means of transport must include labelling of appropriate caution signswhich are placed on a vehicle, on the front and rear side (in the case of road transport). The prescribed caution signtakes the shape of a 30 x 40 cm rectangle. The colour of the background is bright orange, and the field is divided bya horizontal line into two parts. In the upper part it reads a numeric caution sign (2 to 3 digits), and in the lower fileda hazardous material sign (4 digits).The numeric material sign appears in the UN list of Dangerous Goods which are normally transported 45 , whichenables the hazardous material to be identified or to determine the group name of products possessing certainfeatures. It is necessary to underline that labelling of load with hazardous waste from vessels in rail transport is thesame as for road transport, rectangular boards of the same size, but without the brightly coloured orangebackground.Other Provisions in terms of other activities in hazardous materials transport are not reconciled and they areperformed in accordance with the national regulations. It is expected that uniformed caution signs following theGHS system will be adopted, the process on which a number of experts are working: from the OECD, ILO, UNCommittee for hazardous materials transport, as well as numerous experts from America, Europe, Asia andAustralia.Estimate of the influence on the natural environmentTabulated items of the influence on the natural environmentOne of the vital steps in the proposed methodological approach to the classification of hazardous materials ispreliminary consideration of the effects of waste materials from the exploitation of vessels on working and naturalenvironment. For that reason, the researchers have improved a tabulated review of possible influences from theliterature 2 by thoroughly reconsidering potential influences presented in a set of tables. In this paper, the tables forthe first two groups of the typical hazardous materials from vessels have been presented: for metals (Table 7) andfor waste oil and fuels (Table 8).Algorithms for the estimate of the influences on the natural environmentDuring the phase of the realisation of the project, the researchers assigned particular importance to the estimate ofthe influences of hazardous waste and dismantling of ships on the natural environment. Thus, a whole set of originalalgorithms for the circulation of waste has been developed, with the estimate of potential emissions into the naturalenvironment in the processes of treatment and disposal of certain types of waste.For the purpose of this paper, original algorithms of metal circulation have been selected: for waste with mercury(Figure 4), and oiled solid waste (Figure 5) from which we can easily notice possible influences of certain processesin the circulation of waste on the natural environment.
