Class 2 Gases第二類 氣體

Division 2.1
Flammable Gas
RFG
易燃氣體類別 2.1

Any gas which, when mixed with air in certain proportions, forms a flammable mixture.
與空氣混合,可燃輻度至少為12個百分點的氣體。

e.g. Butane, Hydrogen, Propane, Acetylene, Lighters
丁烷、氫、丙烷、乙炔、打火機

Division 2.2 Non-flammable non-toxic gas
RNG
RCL
不易燃, 無毒的壓縮氣體類別 2.2

Any non-flammable, non-toxic gas or low temperature liquefied gas.
非易燃無毒氣體。

e.g. Carbon dioxide, Neon, Fire extinguisher, liquefied Nitrogen or Helium
二氧化碳、氖、滅火器或低溫液化氣體例如液化氮氣或氦氣。

Division 2.3
Toxic Gas
RPG
有毒氣體類別 2.3

Gases known to be toxic or corrosive to humans and known to pose a health risk.
已知具有的毒性或腐蝕性強到對人的健康造成危害的氣體。

Most toxic gases are forbidden for carriage by air; some are permitted, e.g. aerosols of low toxicity, tear gas devices.
具毒性或腐蝕性,對人的健康造成危險的氣體多數毒氣被禁止為使用空運;有些被允許,例如低毒性噴霧劑, 催淚彈等設備。

Class 3 – Flammable Liquid 第三類 易燃液體

Class 3
Flammable Liquid
RFL
易燃液體

Any liquid having a closed cup flash point of 60.oC or below (DGR Appendix A)
易燃液體是指在閉杯試驗中溫度不超60.oC)或以下。

 

e.g. Paints, alcohols, some adhesives, acetone, petrol, etc.
某些油漆、油漆、酒精、某些膠黏劑、丙酮、汽油等。

Class 4 Flammable solids 第四類 易燃固體

Division 4.1
Flammable solid
RFS
易燃固體類別 4.1

Any solids material, which is readily combustible, or may cause or contribute to fire through friction
易燃固體,指在正常運輸條件下,易於燃燒的固體和摩擦可能起火的固體;自身反應物質是指容易發生激烈放熱分解的物質;鹹敏的爆炸品是指不充分稀釋就可能爆炸的物質。

e.g. Matches, Sulphur, Celluloid, Nitronaphthalene. Note: some are self-reactive.
火柴、硫磺、明膠、硝基。 注︰某些是自我反應物質。

Division 4.2 Spontaneously Combustible
RSC
自燃物品類別 4.2

Such substances are liable to spontaneous heating or to heating up in contact with air and then liable to catch fire.
自然物質係指在正常運輸條件下能自發放熱,或接觸空氣能夠放熱;並隨後起火的物質。

e.g. White or Yellow phosphorous, Magnesium diamide.
白色或黃色磷、鎂聯氨。

Division 4.3
Dangerous When Wet RFW
遇濕易燃物品類別 4.3

Substances, which by interaction with water, are liable to become spontaneously flammable or give off flammable gases.
與水接觸釋放出易燃氣體(遇濕危險)的物質。這種物質與水反應自燃或產生足以構成危險數量的易燃氣體。

e.g. Calcium carbide, sodium.
鈣碳化物、鈉。

Class 5 Oxidizing substance; organic peroxide 第五類 氧化劑

 

 

Division 5.1
Oxidizer
ROX
氧化劑類別 5.1

A substance that yields oxygen readily to stimulate the combustion of other materials.
氧化劑是指本身未必燃燒,但通常因放出氧可能引起或促使其他物質燃燒的物質。這類物質可能含在一種物品內。

e.g. Ammonium nitrate fertilizer, calcium chlorate, bleaches.
硝酸銨肥料、鈣氯酸鹽、漂白劑。

 

Division 5.2
Organic Peroxide
ROP
有機過氧化物
類別 5.2

An organic material (liquid or solid) that can be ignited readily by external flame and then burns with an accelerating rate: some substances react dangerously with others
有機過氧化物遇熱不穏定,它可以放熱並因面加速自身的分解。此外,它們還可能與其他物質發危險的反應。

e.g. tert-Butyl hydroperoxide, as listed in Appendix C of the DGR
丁基過氧化氫, 被列出在《規則》附錄C。
