Fuming HCl is another name for concentrated Hydrochloric Acid. The material is also commonly known as HCl, Muriatic Acid, Fuming Muriatic Acid and Fuming Hydrochloric Acid. Hydrochloric Acid or Fuming HCl is produced by dissolving Hydrogen Chloride in water. There are numerous ways in which Hydrogen Chloride can be produced, therefore the production of Fuming HCl has numerous methods. Further information on Hydrochloric Acid manufacture can be found on the relevant pages of this website.
Fuming HCl is a strong mineral acid with a wide range of uses both in industry and domestically. Concentrated Fuming HCl is produced in solutions of up to 38%. It is possible to produce solutions with a slightly higher percentage concentration, say of 40%, but here the evaporation rate is too high for normal usage. Therefore, commercially available concentrated Fuming HCl solutions are generally available at between 30% and 34%. When Fuming HCl is used domestically, its concentration is generally in the region of 10% to 12%, although this may be diluted further before use.
Amongst its uses in industry, Fuming HCl is an important acid in steel-making as it can effectively remove rust from metal. In the steel industry, this process is often described as 'pickling' metal. Fuming HCl is also widely used in food preparation, both for canning produce and also in the manufacture of corn syrups and soft drinks. Fuming HCl is used in the manufacture of Vinyl Chloride for the PVC (Poly Vinyl Chloride) industry. Fuming HCl is also used extensively in the building trade for brick cleaning and concrete etching. In the home, Fuming HCl is found in dilute forms in many household cleaning products. It is also used to maintain swimming pools.
Fuming HCl is a highly 'Corrosive' material and care should be taken when handling or working with it. Full details of potential Hydrochloric Acid hazards and Hydrochloric Acid safety can be found on the relevant pages of this website. It is essential that all potential hazards are rad and clearly understood before commening working with this material. Personal Protective Equipment (PPE) should always be worn when working with Fuming HCl and should include eye protection, foot protection and protective clothing, with respiratory equipment, fume extraction and full face protection, according to the quantities involved. Fuming HCl must always be used in a well-ventilated area.
Government legislation controls the packaging, labelling and transporting of Hydrochloric Acid. Hydrochloric Acid is classified as 'Corrosive' above 25% solution according to the CHIP Regulations, 'The Chemicals (Hazard Information and Packaging for Supply) Regulations 2009'. Risk and Safety Phrases apply to Fuming HCl and further details of these requirements can be found on the relevant pages of this site.
The 'Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009' governs transporting Hydrochloric Acid in the UK whilst the ADR Regulations is the name given to the Agreement covering the transport of dangerous goods in Europe. Again, full details of these and other requirements can be found on the Transporting Hydrochloric Acid webpage of this site.
