N Class or Division / Subsidiary Risks

ALLYL ALCOHOL
107-18-6

The vapour is heavier than air and may travel along the ground; distant ignition possible

On combustion, forms carbon monoxide • Upon heating, toxic fumes are formed • Reacts with carbon tetrachloride, nitric acid, chlorosulphonic acid causing fire and explosion hazard

6.1/ 3

BENZYL ALCOHOL
100-51-6

Reacts violently with strong oxidants and acids • Attacks many plastics • Can attack iron, aluminium upon heating • Slow oxidation in the presence of air

BUTYL ALCOHOL
71-36-3

3

sec-BUTYL ALCOHOL
78-92-2

6.1/3

ETHANOL
64-17-5

The vapour mixes well with air, explosive mixtures are easily formed

On combustion, forms toxic gases • Reacts slowly with calcium hypochlorite, silver oxide and ammonia, causing fire and explosion hazard • Reacts violently with strong oxidants such as nitric acid, silver nitrate, mercuric nitrate or magnesium perchlorate, causing fire and explosion hazard

3

2-ETHYL-1-HEXANOL

2517-43-3

Reacts with oxidants

2-METHYL-4-PENTANOL
108-11-2

The vapour is heavier than air and may travel along the ground; distant ignition possible

Reacts with oxidants • Reacts violently with alkali metals causing fire and explosion hazard

3

METHYLCYCLOHEXANOL
25639-42-3

On combustion, forms toxic gases

3

o-METHYLCYCLOHEXANOL
583-59-5

Reacts with strong oxidants

3

2-PHENYLETHANOL
60-12-8

Reacts with strong oxidants, strong acids

PROPANOL
71-23-8

The vapour mixes well with air, explosive mixtures are easily formed

Reacts with strong oxidants (perchlorates, nitrates)

3

PROPARGYL ALCOHOL
107-19-7

The vapour is heavier than air

Reacts violently with oxidants • Attacks many plastics • On contact with heavy metals, poorly soluble salts may be formed, which may explode on heating

TETRAHYDROFURFURYL ALCOHOL
97-99-4

The substance can presumably form explosive peroxides • The substance decomposes on heating producing acrid smoke and fume • Reacts violently with strong oxidants, several n-chloro- and n-bromoimides causing fire and explosion hazard • Attacks many resins and organic materials

3,5,5-TRIMETHYL 1-HEXANOL
3452-97-9

The vapour is heavier than air

May explode on heating • Reacts with strong oxidants, inorganic acids, aldehydes, alkenoxides, acid anhydrides • Reacts with rubber, PVC

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; 7 = radioactive; 8 = corrosive substance.
