ANNEX. Exposure scenario for ingredients
EXPOSURE SCENARIO SODIUM HYDROXIDE
1.
Short title of exposure scenario: Professional use
Sector of use (SU). SU 22
Product category (PC). PC35
Process category (PROC). PROC19
Environmental release category (ERC). ERC8a
2. Contributing scenario controlling environmental exposure
Product characteristiques Concentrations up to 100%.
Use frequency Continuous exposure.
Technical conditions and specific measures to prevent or limit
discharges, air emissions and release to soil
Regular control of pH value during introduction into open waters is required. In
general discharges should be carried out such that pH changes in receiving surface
aters are minimized. In general most aquatic organisms can tolerate pH values in
the range 6-9. This is also reflected in the description standard OECD tests with
aquatic organisms. Risk management measures related to the environment aim to
avoid discharging the substance into municipal wastewater or to surface water, in
case such discharges are expected to cause significant pH changes.
Conditions and measures related to external treatment of waste
for disposal
Waste should be reused or discharged to the industrial wastewater and further
neutralized if needed.
3. Contributing scenario controlling exposure of workers
Product characteristics.
Concentration up to 100%.
Use frequency.
8 hours / day, 200 days/year.
Technical conditions and measures at the source in order to
prevent releases.
Replace manual procedures with automatic procedures where possible.
Use closed systems or opened systems with coverage.
Use aspiration pumps.
Technical conditions and measures in order to control dispersion
from source toward worker.
Adopt general ventilation.
Organizational measures in order to prevent/limit releases,
dispersions and exposure.
The employer has to ascertain that the required PPE are available for workers.
For the product transfer use pumps in order to avoid splashes.
Conditions and measures related to personal protection, hygiene
and health evaluation.
Protection of airways: in case of aerosols use a respiratory protection with approved
filter P2.
Hands protection: gloves in PVC, neoprene lined with natural rubber, butyl rubber,
material thickness: 0,5 mm, permeation time: > 480 min.
Eyes protection: wear tightly fitting safety goggles, face-shield.
Skin protection: wear suitable protective clothing, aprons, shield and suits, rubber
or plastic boots.
