Section 2.2 Control of environmental exposure Operational conditions
Amounts used
Maximum daily site tonnage (kg/day): 2100
Frequency and Duration of use/exposure
Emission days (days/year): 225
Environmental factors not influenced by risk management
Local fresh water dilution factor: 10 Local marine water dilution factor: 100
Other Operational Conditions of use affecting environmental exposure
n/a Risk Management Measures
Technical conditions and measures at process level (source) to prevent release
n/a
Technical onsite conditions and measures to reduce or limit discharges, air emissions and releases to soil
Containement
Organisation measures to prevent/limit release from site
Site should have a spill plan to ensure that adequate safeguards are in place to minimize the impact of episodic releases.
Conditions and measures related to municipal sewage treatment plant
STP: 3 Estimated substance removal from wastewater via domestic sewage treatment (%): 87.3 (default from Simple treat model) STP4: Total efficiency of removal from wastewater after onsite and offsite (domestic treatment plant) RMMs (%): 87.3
Conditions and measures related to external treatment of waste for disposal
Dispose of waste solvent and used containers according to local regulations
Conditions and measures related to external recovery of waste
Storage of finished products in closed containers (e.g., bulk tanks,, drums, cans). Incinerate, absorb, or adsorb vapours stripped from solution whenever necessary.
Other environmental control measures additional to above
Vapour recovery units should be used when necessary. Section 3 Exposure Estimation 3.1. Health
The ECETOC TRA tool has been used to estimate workplace exposures unless otherwise indicated. 3.2. Environment
EUSES version 2.1. has been used to estimate environmental emissions unless otherwise indicated. When the recommended risk management measures and operational conditions are observed, exposures are not expected to exceed the predicted PNECs and the resulting risk characterisation ratios are expected to be less than 1. Section 4 Guidance to check compliance with the Exposure Scenario 4.1. Health
Estimated workplace exposures are not expected to exceed DNELs when the identified risk management measures are adopted. Where other Risk Management Measures/Operational Conditions are adopted, then users should ensure that risks are managed to at least equivalent levels. 4.2. Environment
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. Further details on scaling and control technologies are provided in spERC factsheet (http://cefic.org/en/reeach-for-industries-libraries.html).
