[edit] Hazard Symbols

Corrosive substances such as Nitric Acid can cause burns. Handle with care.

Explosive substances such as Nitroglycerin can explode if heated or exposed to shock

Flammable substances such as Propane are hazardous when there flash point is exceeded

Ecotoxins such as Petrol can be very toxic to fish

Oxidising Agents such as Oxygen or Sodium Nitrate reduce them self to Oxidise reducing agents such as Sulfur

Toxic substances such as Chlorine gas or Sulfur Dioxide have fatal toxicity if ingested, inhaled or in skin contact

Harmful substances such as Copper Oxide can be harmful or fatal in large doses.

Irritants such as Washing Soda can irritate the skin or eyes. Gloves and safety glasses should be worn.

Explosive Substances should NOT be heated or exposed to shock

Safety Glasses and Gloves and should be used for Corrosive or Toxic Chemicals

Oxidising Agents should be stored away from sources of fuel and reducing agents.

Ecotoxins SHOULD NOT be poured down sinks or drains in large amounts.

Flammable Substances should be away from any sources that might ignite them.

Above NFPA 704 'Fire Diamonds' for sulfuric Acid, hydrogen cyanide and hydrogen oxide (water)

[edit] Blue - Health

  • 4.  Very short exposure could cause death or major residual injury (e.g., hydrogen cyanide).
  • 3.  Short exposure could cause serious temporary or moderate residual injury (e.g., chlorine gas).
  • 2.  Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury (e.g., chloroform).
  • 1.  Exposure would cause irritation with only minor residual injury (e.g., turpentine).
  • 0.  Poses no health hazard, no precautions necessary. (e.g., lanolin).

[edit] Red - Flammability

  • 4.  Will rapidly or completely vaporize at normal atmospheric pressure and temperature, or is readily dispersed in air and will burn readily (e.g., propane). Flash point below 23°C (73°F).
  • 3.  Liquids and solids that can be ignited under almost all ambient temperature conditions (e.g., gasoline). Flash point below 38°C (100°F) but above 23°C (73°F).
  • 2.  Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur (e.g., diesel fuel). Flash point between 38°C (100°F) and 93°C (200°F).
  • 1.  Must be pre-heated before ignition can occur (e.g., canola oil). Flash point over 93°C (200°F).
  • 0.  Will not burn (e.g., argon).

[edit] Yellow - Instability/Reactivity

  • 4.  Readily capable of detonation or explosive decomposition at normal temperatures and pressures (e.g., nitroglycerine, RDX).
  • 3.  Capable of detonation or explosive decomposition but requires a strong initiating source, must be heated under confinement before initiation, reacts explosively with water, or will detonate if severely shocked (e.g., fluorine).
  • 2.  Undergoes violent chemical change at elevated temperatures and pressures, reacts violently with water, or may form explosive mixtures with water (e.g., phosphorus, potassium compounds, sodium compounds).
  • 1.  Normally stable, but can become unstable at elevated temperatures and pressures (e.g., acetylene (ethyne)).
  • 0.  Normally stable, even under fire exposure conditions, and is not reactive with water (e.g., helium).
