CHLOROSULPHURIC ACID
7790-94-5

8

FLUOROSULPHURIC ACID
7789-21-1

8

HYDROCHLORIC ACID
7647-01-0

The gas is heavier than air

The solution in water is a strong acid, it reacts violently with bases and is corrosive • Reacts violently with oxidants forming toxic gas (chlorine) • On contact with air it emits corrosive fumes (hydrochloric acid) • Attacks many metals forming combustible gas (HYDROGEN)

8

HYDROFLUOBORIC ACID
16872-11-0

8

NITRIC ACID
7697-37-2

The substance decomposes on warming producing nitrogen oxides • The substance is a strong oxidant and reacts violently with combustible and reducing materials, eg, turpentine, charcoal, alcohol • The substance is a strong acid, it reacts violently with bases and is corrosive to metals • Reacts very violently with organic chemicals (eg, acetone, acetic acid, acetic anhydride), causing fire and explosion hazard • Attacks some plastics

8

PERCHLORIC ACID
7601-90-3

5.1/ 8

PHOSPHORIC ACID
7664-38-2

The substance violently polymerizes under the influence of azo compounds, epoxides and other polymerizable compounds • On combustion, forms toxic fumes (phosphorous oxides) • The substance decomposes on contact with metals, alcohols, aldehydes, cyanides, ketones, phenols, esters, sulfides, halogenated organics producing toxic fumes • The substance is a medium strong acid • Attacks metals to liberate flammable hydrogen gas

8

SULPHAMIC ACID
5329-14-6

8

SULPHURIC ACID
7664-93-9

On combustion, forms toxic fumes (sulphur oxides) • The substance is a strong oxidant and reacts violently with combustible and reducing materials • The substance is a strong acid, it reacts violently with bases and is corrosive to most common metals forming a flammable/explosive gas (hydrogen) • Reacts violently with water and organic materials with evolution of heat • Upon heating, irritating or toxic fumes (or gases) (sulphur oxides) are formed

8

For UN Class: 1.5 = very insensitive substances which have a mass explosion hazard; 2.1 = flammable gas; 2.3 = toxic gas; 3 = flammable liquid; 4.1 = flammable solid; 4.2 = substance liable to spontaneous combustion; 4.3 = substance which in contact with water emits flammable gases; 5.1 = oxidizing substance; 6.1 = toxic; = radioactive; 8 = corrosive substance.
