SAFETY LABELS

Substances that made explode under definite conditions. Avoid shock, friction, sparks and heat:
Substances that can ignite combustible material or worsen existing fires and thus make fire-fighting more difficuls. Keep away from combustible material:
Spontaneously flammable substances. Avoid contact with air. Highly flammable gases and flammable liquids. Keep away from open fires, sources of heat and sparks:
Substances that very hazardous to health when breathed, swallowed or in contact with the skin and may even lead to death. Avoid contact with the human body:
Substances that can destroy living tissue as well as equipment. Do not breathe vapours and avoid contact with the skin, eyes and clothing:
Symbol that designates substances that may have irritant effects on skin, eyes and respiratory organs. Do not breathe vapours and avoid contact with skin and eyes:
Substances that when taken up by the body cause slight damage. Avoid contact with the human body, including inhalation of the vapours:
