9. Guidelines for the upstream user to assess if working between the limits established by the Exposure Scenario Users are advised to apply the occupational exposure limits set nationally or other equivalent values. On other measures of risk management / operational conditions, users should ensure that risks are managed at least at the same levels. Guidance is based on assumed operating conditions which may not be applicable to all sites; thus, scaling may be necessary to define appropriate site-specific risk management measures. If scaling reveals a condition of unsafe use (i.e., RCRs > 1), additional RMMs or a site-specific chemical safety assessment is required [DSU8]. Further details on scaling and control technologies are provided in SpERC factsheet (http://cefic.org/en/reach-for-industries-libraries.html). The workers' exposure to MTBE may principally occur only during incidental leaks and spills from pipeline and valve connections (fugitive emissions) and maintenance operations. In formulation (blending and storing) operations, exposure might either concern neat MTBE or blended fuel. Sampling and laboratory work, handling products containing MTBE for analyses, lead to exposure of laboratory assistants. The mechanics are daily exposed during removal of pumps and repairing repellers. They are also doing maintenance on pipelines and vapour recovery equipment. The maintenance tasks are such that the workers are exposed to MTBE vapours and their hands are in contact with petrol products.

On other measures of risk management / operational conditions, users should ensure that risks are managed at least at the same levels. Guidance is based on assumed operating conditions which may not be applicable to all sites; thus, scaling may be necessary to define appropriate site-specific risk management measures. If scaling reveals a condition of unsafe use (i.e., RCRs > 1), additional RMMs or a site-specific chemical safety assessment is required [DSU8].

Transporting operations concerns both neat MTBE and mixed fuel. The exposed workers are bulk terminal, railcar, truck and marine employees. Leaks from the fittings and dry break mating surfaces contribute to the operators’ exposure during the loading/unloading operations. The severity of drivers' exposure to petrol vapours depends on the method of loading (top loading or bottom loading), and how the vapours from the empty tanks are displaced, recovered or vented. Exposure can be the result of the following loading/unloading activities (as described in the RAR, European Commission, 2002): Unloading of a railroad car (disconnecting the bottom cap from the rail car, connecting a male unloading elbow, and connecting a female unloading dry break to the male elbow for product transfer to a storage tank) Loading and delivery operations (The major part of exposure of road tanker drivers takes place during loading and delivery operations. The principal source for workers' exposure at depot area is created by the flow of petrol into the truck tank. The petrol flow displaces petrol vapours from the truck tank into the atmosphere or into a vapour recovery system. Leaking from the filling lines or spillage of petrol may also produce vapours through evaporation) Disconnecting the bottom cap from the truck (at service stations for product transfer to the storing tank), connecting a male unloading elbow, and connecting a female unloading dry break to the male elbow. Spills and leaks from the fittings and dry break mating surfaces contribute to the driver's exposure. The highest short-term exposures may occur during the connecting and disconnecting the dry break valves. Saturated petrol vapours escaping from the tanks when the tanks are filled with new liquid likely causes the main exposure. Taking samples: During transportation, also samplings for laboratory analyses are required by removal an unloading valve cap located underneath the car, installing a sample valve, and filling a glass bottle for sampling. The operators' exposures increase especially while handling the wetted valves. After finishing the sampling, the valves become plugged and then cleaned. The bucket used to drain the overflow of the sampling increases the exposure. Mechanics are daily exposed during removal of pumps and repairing repellers, during replacement of railroad car dry break couplings, and while repairing and calibrating fuel meters at transport loading racks and at service stations. They are also doing maintenance on pipelines and vapour recovery equipment. The maintenance tasks are such that the workers are exposed to MTBE vapours and their hands are in contact with petrol products.

9. Guidelines for the upstream user to assess if working between the limits established by the Exposure Scenario

Users are advised to apply the occupational exposure limits set nationally or other equivalent values. On other measures of risk management / operational conditions, users should ensure that risks are managed at least at the same levels. Guidance is based on assumed operating conditions which may not be applicable to all sites; thus, scaling may be necessary to define appropriate site-specific risk management measures. If scaling reveals a condition of unsafe use (i.e., RCRs > 1), additional RMMs or a site-specific chemical safety assessment is required [DSU8]. Further details on scaling and control technologies are provided in SpERC factsheet (http://cefic.org/en/reach-for-industries-libraries.html).

RISK CHARACTERISATION Workers Within each scenario, the potential for contributing scenarios is not aggregated. Tasks are 8-hours, with the exception of: • Sampling (15 mins) • Bulk loading and unloading (4 hours) • Transfer / Pouring from containers (1 hour) • Equipment cleaning and maintenance (4 hours) For the above specific tasks, exposure estimates are based on the time durations indicated. Due to the high tonnage of the product and end-uses, manufacturing and formulation are likely to occur at large sites, mostly with dedicated facilities, with developed EHS management systems. It is for the site EHS managers to ensure that combination of tasks do not result in RCR>1. As the RCR from a task is at maximum around. 0.5, it is feasible to combine at least two tasks on a given day without further refining the exposure estimates. Multiple tasks or repetition of a short task (1 hour or 15 mins) in the same day would require further assessment/ additional measures with the use of scaling by the downstream user . However it is unlikely that multiple tasks would be performed by the same personnel in the same day. For exemple: • Loading/ unloading may be done at another site from where manufacture occurs, as the product leaves the manufacturing site by pipeline • Loading / unloading is typically done on a per batch basis by operators specialised in that task,which is separate to manufacturing and formulation activities or performed by third party (contractors) as part of transport services • Manufacturing and formulation are typically done at different sites • Sampling is most likely for downstream user formulation on a batch basis, where the high tonnage would limit the likelihood for multiple batches on any given day • Equipment cleaning and maintenance is typically done by mechanical/ technical experts and only performed on at end of a manufacturing campaign / batch or on occasions where there is a need to replace equipment • Use in a laboratory, such as analysis of samples, is typically done by dedicated staff
