c) Respiratory protection The vapours are heavier than air and can cause asphyxia caused to an reduction of oxygen level.
In case of insufficient ventilation, wear self-contained breathing apparatus (EN 133).
OTHER/GENERAL PROTECTION
Safety shoes, safety shower, eyewash
8.2.3. Environmental exposure controls
Handling in accordance with good industrial hygiene and safety practice.
Prevent spillage or leakage of the product in watercourse or sewers (explosion danger). Avoid air emissions.
For more information, see section 7.
