          Compusii cancerigeni si compusii inflamabili marcati ca "toxici" sau "foarte toxici": container F. Alchili-sulfatii sunt cancerigeni. Luati masuri speciale pentru a evita inhalarea sau contactul cu pielea. Pentru neutralizarea alchil-sulfatilor, acestia se adauga in picaturi (cu o palnie de picurare) in solutie concentrata de amoniac racita cu gheata (Cod Merck 105426) agitand puternic. Inainte de colectarea in containerul D, verificati pH-ul cu strip-uri indicatoare pH, universale (Cod Merck 109535).
