- Cleaning/Decontamination : Wash the non-recoverable remainder with caustic soda solution (2-5 % NaOH).
Then wash the floor with plenty of water. Recover the cleaning water for subsequent disposal.
- Disposal : Dispose of solid materials at an authorized site.
Dispose of in accordance with local regulations.
Handling and storage
HANDLING
-Technical measures : Provide adequate ventilation. Dust extraction (suction).
Use of Local Exhaust Ventilation for each activity, except for those occurring outdoors and for the exposure scenario "addition of solid TBC in monomers".
-Measures: Avoid the formation or spread of dust in the atmosphere. Avoid any direct contact with the product.Do NOT handle without gloves.
Minimisation of manual phases/work tasks
Minimisation of splashes and spills,
Avoidance of contact with contaminated tools and objects
If molten : Avoid splashes.
-Safe handling advice : Comply with instructions for use (refer to technical sheet). obtain special instructions before use.
The product must only be handled by specifically trained employees.
For more information on safe handling, please refer to "personal protection equipment".
STORAGE
-Technical measures : Local ventilation required when opening heated packaging.
Storage conditions
-Recommended : To guarantee the quality and properties of the product keep: - protected from air. - protected from light.
-Incompatible products : Strong oxidizing agents. Alkalis and caustic products.
Packaging materials:
- Recommended : Galvanized steel.Plastic materials (polyethylene). Galvanised drums. Plastic drums.

Exposure controls / personal protection
Engineering measures :
-Facilities and equipment easily cleanable.
-If molten : Avoid splashes.
-Apply technical measures to comply with the occupational exposure limits.
-Extraction to remove dust at its source.
-Provide adequate ventilation.
Personal protective equipment
- Respiratory protection
Use a respirator with an approved filter if a risk assessment indicates this is necessary.
Respirator with a particle filter (EN 143)
In short-term processes where contact to substance cannot be excluded (e.g. sampling operations) and where the opportunity for exposure is higher than reference value, a combination of activated carbon filter and particulate filter can be used.
If vapour is released (molten product):
Respirator with a vapour filter (EN 141) with a specific gas canister.
- Eye protection :
Safety goggles (material : polycarbonate or equivalent)
In case of contact through splashing (molten product): Wear face-shield and protective suit.
A mask is required for manual cleaning and maintenance of the equipments, sampling blend before packaging (outdoor), off loading into container (outdoor), off loading into drums (outdoor), sampling drums (outdoor) and for addition of TBC during storage of the monomers.
- Hand protection :
Where there is a risk of contact with hands, use appropriate gloves.
The selected protective gloves have to satisfy the specifications of Regulation (EU) 2016/425 and the standard EN 374 derived from it.
Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. Also take into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion, and the contact time.
Gloves must be inspected prior to use.
Gloves should be discarded and replaced if there is any indication of degradation or chemical breakthrough.
Long protective gloves, which go over the sleeves.
- Skin and body protection:
Choose body protection according to the amount and concentration of the dangerous substance at the work place.
Remove and wash contaminated clothing.
