Dangerous and flammable substances



Dangerous and flammable items not allowed to be sent by post

EXPLOSIVES

 
Definition
Any chemical compounds, mixtures or agents potentially able to cause an explosion or the use of which is accompanied by momentary heating and a risk of gas diffusion. All explosives are prohibited.
 
Examples
nitroglycerine, Christmas crackers, salute rockets, fuel-air mixtures, detonators, fireworks, ammunition etc.

 

GASES (compressed, liquefied or dissolved under pressure)

 
Definition
Stable gases that cannot be liquefied at ambient temperatures, dissolved under pressure. The following substances are forbidden:
  • compressed flammable gases: hydrogen, ethane, methane, propane, butane, lighter fuel, gas cylinders for camping stoves, blowlamps etc.
  • toxic compressed gases: chlorine, fluorine etc.
  • non-flammable compressed gases: carbon dioxide, nitrogen, neon, fire-extinguishing equipment containing such gases etc.
  • aerosol sprays
 

FLAMMABLE LIQUIDS

 
Definition
Liquids, mixtures of liquids or liquids containing solid particles in solution or as suspension creating burning vapours. All liquids with ignition temperatures of less than 55?C when in a closed container.
 
Examples
acetone, benzol, cleaning agents, petrol, lighter fuel, paint thinners and cleaning agents, kerosene, solvents etc.

 

FLAMMABLE SOLIDS

 
Definition
Solid materials able to ignite due to friction, absorption of moisture, spontaneous chemical reactions or heat retained from manufacturing or processing, or which can be easily ignited and burn.

 

Examples
matches, calcium carbide, cellulose, substances containing nitrates, metallic magnesium, nitrocellulose-based film, phosphorous, potassium, sodium, sodium hydride, zinc powder, zirconium hydride etc.

 

OXIDANTS AND ORGANIC PEROXIDES

 
Definition
These substances can self-ignite, occasionally causing or stimulating the combustion of other substances. They may also explode, cause dangerous reactions with other substances, and damage health.
 
Examples
bromides, chlorates, components of fibreglass fixing agents, nitrates, perchlorates, permanganates, peroxides etc.

 

TOXIC SUBSTANCES AND SUBSTANCES CAUSING THE SPREAD OF INFECTION; OTHER MEDICAL SUBSTANCES

 
Definition
Substances potentially causing death or damage to health after swallowing, inhalation or contact with the skin. Substances containing micro-organisms or their toxins that may facilitate the spread of disease.
 
Examples
arsenic, beryllium, cyanide, fluorine, hydrogen, selenite, mercury, mercury salts, iprite, nitrogenous dioxide, pathogenic material, rat poison, serum, vaccines etc.
 

RADIOACTIVE MATERIAL

 
Definition
All materials with specific activity exceeding 74 kilobecquerels per kilo (0.002 microcuries per gram). All radioactive materials are prohibited.
 
Examples
fissile substances (uranium 235 etc.); radioactive waste, uranium ore, thorium ore etc.
 

CORROSIVES

 
Definition
Substances that can cause substantial harm due to their chemical effect on living tissues, items or freight vehicles.
 
Examples
aluminium chloride, sodium hydroxide, caustic cleaning agents, corrosion removal/protection agents, caustic paint remover, electrical batteries, hydrochloric acid, nitric acid, sulphuric acid etc.
 

OTHER DANGEROUS ITEMS

 
Definition
Substances causing danger that cannot be classified in any of the other categories.

 

Examples
asbestos, dry ice, magnetised material with a magnetic power of 0.159 ? or more at a distance of 2.1 m from packaging etc.
