How Dangerous is Muriatic Acid?
As a strong acid, muriatic acid is extremely dangerous if ingested, inhaled or in contact with skin. If ingested or inhaled, muriatic acid quickly dissociates and its harmful effects derive from strong localised pH changes rather than the effects of the acid itself.- Corrosive: Muriatic acid is highly corrosive to the skin and eyes, as well as highly irritant to the respiratory tract. Studies have reported that doses as low as 10ppm to cause symptoms of irritation. Safety procedures recommend staff evacuation in case of large spillages, enough to detect the odour in the air.
- Carcinogenic: Studies with lab animals showed an increased incidence of tumours or abnormal growths after inhalation or dermal administration. Also, in humans, there is no evidence of higher tumour incidence in workers regularly exposed to this chemical.
- Effect on reproduction: There are no reliable studies indicating whether or not muriatic acid can have harmful effects on fertility or during pregnancy, after ingestion, inhalation or skin contact. As both H and Cl are constituents of normal metabolism, it’s expected that the body can deal with small amounts of this chemical and excrete excessive quantities in an efficient manner.
- Impact on the environment: Due to pH changes, muriatic acid can have a strong impact on the environment. The response depends on the ability to buffer any changes, particularly in an aquatic environment. For this reason, LC50 values vary widely for different species and different ecosystems.
