Manufacture (Heavy fuel oil) - Industrial Industrial List of use descriptors Identified use name: Manufacture of substance Process Category: PROC01, PROC02, PROC03, PROC08a, PROC08b, PROC15 Subsequent service life relevant for that use: No. Environmental Release Category: ERC01 Section 1: Title Short title of the exposure scenario Code STI2299 Product definition UVCB Product name Fuel Oil, residual Identification of the substance or mixture Processes and activities covered by the exposure scenario Manufacture of substance. Includes material transfers, storage, sampling, associated laboratory activities, maintenance and loading (including marine vessel/ barge, road/rail car and bulk container). Assessment Method See Section 3 ESVOC SpERC 1.1.v1 Specific Environmental Release Category: Annex to the extended Safety Data Sheet (eSDS) Section 2.1 Control of worker exposure Product characteristics: Physical state: Liquid, vapour pressure < 0.5 kPa at Standard Temperature and Pressure Other conditions affecting workers exposure: Operation is carried out at elevated temperature (> 20°C above ambient temperature) Assumes a good basic standard of occupational hygiene is implemented Contributing scenarios: Operational conditions and risk management measures Frequency and duration of use: Covers daily exposures up to 8 hours (unless stated differently). Section 2 Operational conditions and risk management measures General measures (carcinogens): Consider technical advances and process upgrades (including automation) for the elimination of releases. Minimise exposure using measures such as closed systems, dedicated facilities and suitable general/local exhaust ventilation. Drain down systems and clear transfer lines prior to breaking containment. Clean/flush equipment, where possible, prior to maintenance. Where there is potential for exposure: restrict access to authorised persons; provide specific activity training to operators to minimise exposures; wear suitable gloves and coveralls to prevent skin contamination; wear respiratory protection when its use is identified for certain contributing scenarios; clear up spills immediately and dispose of wastes safely. Ensure safe systems of work or equivalent arrangements are in place to manage risks. Regularly inspect, test and maintain all control measures. Consider the need for risk-based health surveillance. General exposures (closed systems): Handle substance within a closed system. Wear chemical-resistant gloves (tested to EN374) in combination with 'basic' employee training. Process sampling Outdoor: Sample via a closed loop or other system to avoid exposure. Avoid carrying out activities involving exposure for more than 15 minutes per day. Wear chemical-resistant gloves (tested to EN374) in combination with 'basic' employee training. Bulk product storage: Store substance within a closed system. Avoid carrying out operation for more than 4 hours. Wear chemical-resistant gloves (tested to EN374) in combination with 'basic' employee training. Laboratory activities: Handle within a fume cupboard or implement suitable equivalent methods to minimise exposure. Wear suitable gloves tested to EN374. Marine vessel/barge: Avoid carrying out activities involving exposure for more than 4 hours per day. Transfer via enclosed lines. Clear transfer lines prior to de-coupling. Retain drain-downs in sealed storage pending disposal or for subsequent recycle. Wear chemical-resistant gloves (tested to EN374) in combination with 'basic' employee training. Concentration of substance in product: Covers percentage substance in the product up to 100 %. 34/38 Manufacture (Heavy fuel oil) - Industrial Fuel Oil, residual
