Corrosive (HCl, NaOCl, NaOH)

These substances destroy living tissues and equipment upon contact

Oxidizer

Substances can ignate flammable and combustible substances. Caution: keep away from flammable, combustible and spontaneously combustible substances

Toxic

Very hazardous to health when inhaled, swallowed or when they come in contact with the skin. May lead to death. Caution: avoid contact with the human body and call the physician in case of contact

Flammable liquids

caution: flash point below 141°F (60.5 °C)

Flammable Solids

Caution: keep away from open fires, sources of sparks and heat

Combustible material

caution: flash point greater than 141° F (60.5 °C) but less than 200 F (90° C). Keep away from any sources of heat and sparks and open flames

Store away from foodstuffs.

Toxic and poisonous materials which are hazardous to health when inhaled, swallowed or when it comes in contact with skin.

Radioactive

These are materials with measurable radioactivity.

Harmful to aquatic environment

Very toxic to aquatic organisms. May cause long-term effects to aquatic environment

Explosives

are considered as all products and preparations, if they explode through ignition or if they are more sensitive than nitrobenzene towards blows and friction.
