Just something to think about for users of muriatic (hydrochloric) acid for rust removal. Taken from MSDS safety sheets.
Toxicity:
Skin contact: Burning, inflammation, blisters.
Eye contact: Burning, watering.
Inhalation: Irritation of mucous membranes, watering of eyes, difficulty breathing, salivation, nausea.
Ingestion: Pain in swallowing, intense thirst, abdominal pain, nausea, may be fatal if swallowed.
Preventative Measures
Personal Protective Equipment: Avoid contact with skin and eyes. Wear chemical protective gloves, goggles and face shield, rubber apron and boots. Eye wash fountains and safety shower facilities should be provided nearby for emergency use.
Respiratory protection: For acid vapours and mist, use an NIOSH/MSHA approved air purifying, dust, mist and particulate respirator.
Ventilation Requirements: This product should be used in a well-ventilated area at all times. If the hydrochloric acid solution is to be heated or a mist will be generated during product application, then local exhaust ventilation will be necessary.
It also produces flammable hydrogen gas when reacting with metal so no smoking or open flames.
