      Disposal9
      Senyawa karsinogenik dan senyawa yang dapat terbakar yang berlabel "Very Toxic" (Sangat beracun) atau "Toxic" (beracun) : kategori F. Alkil sulfat bersifat karsinogenik. Berhati-hatilah untuk menghindari penghirupan dan kontak dengan kulit. Untuk menghilangkan keaktifan alkil sulfat, tambahkan tetes per tetes (dari dalam corong tetes) ke dalam larutan amonia pekat dingin-es (Kat. No. 105426), dengan terus diaduk kuat. Sebelum ditempatkan di dalam kategori D, periksa pH dengan indikator pH universal (Kat. No. 105426).
