1. Incinerators designed to destroy chemicals specified in entry 1C350, having specially designed waste supply systems, special handling facilities and an average combustion chamber temperature greater than 1273 K (1000 °C), in which all surfaces in the waste supply system that come into direct contact with the waste products are made from or lined with any of the following materials: 1. Alloys with more than 25 % nickel and 20 % chromium by weight; 2. Ceramics; or 3. Nickel or alloys with more than 40% nickel by weight. Technical Note: 'Carbon graphite' is a composition consisting of amorphous carbon and graphite, in which the graphite content is eight percent or more by weight. 2B351 Toxic gas monitoring systems, as follows; and dedicated detectors therefor: a. Designed for continuous operation and usable for the detection of chemical warfare agents or chemicals specified in 1C350, at concentrations of less than 0,3 mg/m3; or b. Designed for the detection of cholinesterase-inhibiting activity. 2B352 Equipment capable of use in handling biological materials, as follows: a. Complete biological containment facilities at P3, P4 containment level; Technical Note: P3 or P4 (BL3, BL4, L3, L4) containment levels are as specified in the WHO Laboratory Biosafety manual (2nd edition, Geneva 1993). b. Fermenters capable of cultivation of pathogenic "micro-organisms", viruses or capable of toxin production, without the propagation of aerosols, and having a total capacity of 20 litres or more; Technical Note: Fermenters include bioreactors, chemostats and continuous-flow systems. c. Centrifugal separators, capable of continuous separation without the propagation of aerosols, having all the following characteristics:
