SCHEDULE 3 (continued) Part II Classes of chemicals not specifically named in Part I Sl. No. | Classes in Chemical | Threshold Quantities | | | For application of Rules 61-UC, 61-UE, 61-UF, 61-UK and 61-UM | For application of Rules 61-UH to 61-UJ | (1) | (2) | (3) | (4) | | Group.- 5 -flammable Chemicals | | | 1. | Flammable gases :
Chemicals which in gaseous state at normal pressure and mixed with air become flammable and the boiling point of which at normal pressure is 20°C or below; | 15 t | 200 t | 2. | Highly flammable liquids:
Chemicals which have a flash point lower than 23°C and the boiling point of which at normal pressure is above 20°C; | 1000 t | 50000 t | 3. | Flammable liquids:
Chemicals which have a flash point lower than 65OC and which remain liquid under pressure, where particular processing conditions, such as high pressure and high temperature, may create major accident hazards. | 25 t | 200 t |
Footnotes: (1) This applies to ammonium nitrate and mixture of ammonium nitrate where the nitrogen content derived from the ammonium nitrate is greater than 28% by weight and aqueous solutions of ammonium nitrate where the concentration of ammonium nitrate is greater than 90% by weight. (2) This applies to straight ammonium nitrate fertilisers and to compound fertilizers where the nitrogen content derived from the ammonium nitrate is greater than 28% by weight (a compound fertilizer contains ammonium nitrate together with phosphate and/or potash). CAS Number (Chemical Abstracts Service Number) means the number assigned to the chemical by the Chemical Abstracts Service. |
