Most arsenic compounds are toxic so care must be taken when working in or around the equipment and when handling weak acid, deposits and sludge. Arsenic compounds may cause irritation to the eyes, skin, mucous membrane and respiratory tract.
Under reducing conditions arsenic compounds may convert to the highly toxic arsine gas (AsH3).
Appearance | Arsenic Oxide (As2O3) | Solid: white crystals or powder |
Dissolves in weak acid solutions | ||
Arsenic Sludge | Coarse-grain and pasty material. Often reddish colour due to iron oxide being present. Dusty when dry | |
Odour | Unpleasant onion odour |

Arsenic sludge is not flammable Explosion hazards may be present due to the formation of hydrogen when the sludge comes in contact with zinc, aluminum and other light metals.To follow
The following protective equipment is recommended:
Tightly sealed protective goggles
Respirators with colloidal filter (fine-grain)
Protective plastic or rubber gloves
Protective clothing such as boots, pants coat
Careful personal hygiene is important in preventing exposure to arsenic. Hands should be wash carefully and thoroughly with soap and water prior to eating or drinking.
