Absolutely not. It is a dangerous, corrosive chemical that requires specialised training, safety equipment (gloves, goggles, fume hood), and proper disposal procedures.
It poses a dual hazard: chemical burns from the strong alkali (caustic) and flammability from the alcohol solvent.
Follow the specific Safety Data Sheet (SDS). Generally, evacuate the area, ventilate, wear full PPE, and neutralise/absorb with a recommended material (e.g., weak acid for spills, but never mix chemicals without expert knowledge).
