SODIUM AZIDE
26628-22-8

May explode on heating above melting point, especially on rapid heating causing fire and explosion hazard • The solution in water is a weak base • Reacts with copper, lead, silver, mercury and carbon disulfide to form particularly shock-sensitive compounds • Reacts with acids, forming toxic and explosive hydrogen azide • Very corrosive to aluminium

5.1

SODIUM DICHLOROCYANURATE
2893-78-9

The substance decomposes on heating, on contact with water, producing toxic fumes • The substance is a strong oxidant and reacts violently with combustible and reducing materials • The substance is a strong reducing agent and reacts with oxidants • The solution in water is a weak acid • Reacts violently with many substances causing fire and explosion hazard

1,2,4-TRIAZOLE
288-88-0

Dust explosion possible if in powder or granular form, mixed with air

The substance decomposes on boiling • Upon heating, toxic fumes are formed • Reacts with strong oxidants and strong bases

5.1

TRICHLOROISOCYANURIC ACID
87-90-1

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
