M8 Chemical Agent Detector Paper... Detach a sheet of detector paper from the book and attach it to clothing or place on a surface so it can be exposed to drops of liquid splash of chemical agents. If colored spots appear, chemical agent is present.... M8 paper is used to detect the presence of liquid VGH chemical agents. When a sheet is brought in contact with liquid nerve or blister agents, they react with chemicals in the paper to produce agent specific color changes... V-type nerve agents turn the M8 paper dark green, G-type nerve agents turn it yellow and blister agents(H) turn it red.

DEF

A chemical product which appears under the form of odorless crystals and which was used during World War 1 as an antipersonnel device to generate a smoke causing sneezing and vomiting.

CONT

DA is an abbreviation for Di-phenyl-chlor-arsine, a nose irritant gas used during the Second World War. It has no smell and a delayed action, but causes sneezing, a burning pain in the chest, nose, throat and mouth after a few minutes.

OBS

Clark agents. ... these super agents are ... named after the German term "ChLorierte" [chlorinated] "ARsen" [arsenic] "Kampfstoffe" [chemical agents]. As the name suggests, they contain chlorine and arsenic. Clark I is diphenylchloroarsine and Clark II is diphenylcyanoarsine. They are powerful vomiting agents which could penetrate the early designs of gas mask and force the soldiers to remove them, exposing them to the more dangerous agents such as chlorine gas.

OBS

[Origin of the name "blue cross :"] With German shells, the type of chemical agent can be identified from coloured crosses on the casings :"Blaukreuz"(blue cross) affects the upper respiratory tract; "Weisskreuz"(white) contain irritants affecting the eyes and other moist tissues; "Grünkreuz"(green) affects the lungs; "Gelbkreuz"(yellow) attacks any exposed skin surfaces.

CONT

Parallèlement à l'utilisation de l'ypérite, les Allemands introduisent sur le champ de bataille [...] les premières arsines chargées dans des obus à croix bleue. Il s'agissait de diphénylchloroarsine, un produit solide qui nécessitait une charge explosive suffisante pour assurer la mise en aérosol du produit. Celui-ci était contenu dans une bouteille en verre noyée au milieu de l'explosif dans le corps de l'obus. Le produit, pulvérisé par l'explosion de la charge, se transformant momentanément en vapeur grâce à la chaleur dégagée, était susceptible de traverser les filtres des masques protecteurs. Ses effets incapacitants et sternutatoires devaient alors rendre intolérable le port du masque.

OBS

[Ces toxiques allaient être] utilisés simultanément avec des obus suffocants marqués d'une croix verte ou persistants marqués d'une croix jaune, ce qui valut à la zone infectée de porter le nom de «zone bariolée».

... CR... Newer riot control irritant developed in England in 1962 by the British chemists Higginbottom and Suchitzsky. About 5 times more effective than CS [and] much less toxic than CS. CR is not used in its pure form(a yellow powder) but dissolved in a solution of 80 parts of propylene glycol and 20 parts of water to form a 0. 1-percent CR solution. It is used in solution as a riot control agent. Eye pain, discomfort and excessive tearing occur with sometimes painful sensitivity to strong light or temporary blindness. Symptoms can persist for 15 to 30 minutes. Dubbed "fire gas" by the media because of the burning sensation it caused to the skin of rioters when used in Northern Ireland from 1973-1974. Authorized U. S. Army use in 1974.

CONT

CR gas or dibenzoxazepine... is an incapacitating agent and a lachrymatory agent.... CR is a pale yellow crystalline solid with a pepper-like odour. It is slightly soluble in water and does not degrade in it. CR is usually presented as a microparticulate solid, in the form of suspension in a propylene glycol based liquid. Contrary to its common name, it is not actually a gas but is solid at room temperature.

A treatment, most often SO2, but in some cases H2SO4 or HCl, applied a) After a final chlorine dioxide, hyprochlorite or peroxide stage to destroy residual bleaching agent and remove metal ions which prevents brightness loss and avoids fibre degradation, and to create a pH favourable for brightness stability(alkaline pulps tend to yellow on exposure to light and air) ;b) As a pretreatment before an oxygen stage, which tends to improve both brightness and physical strength, probably by removing metal ions from pulp; and c) Between stages, such as peroxide-hydrosulphite, to eliminate the washing steps by creating acid conditions necessary for the hydrosulphite stage, and to destroy residual peroxide by reduction which would otherwise consume costly hydrosulphite; d) Has been used in place of a chelation stage in a TCF sequence with peroxide. In this application the PH is very important.

SO2 and H2SO4 should be read: SO2 and H2SO4.

Traitement pour lequel le SO2 est le plus souvent utilisé. Dans certains cas, on utilise également le H2SO4 ou le HCl. a) Utilisé en fin de séquence, après un traitement au bioxyde de chlore, à l'hypochlorite ou au peroxyde, il permet de détruire les résidus d'agents de blanchiment et d'enlever les ions métalliques. Ce traitement prévient la perte de blancheur (jaunissement) et la dégradation des fibres. Bref, un pH favorable à la stabilité de la blancheur est obtenu (les pâtes alcalines ont tendance à jaunir sous l'action de la lumière et de l'air). b) Utilisé comme prétraitement avant un traitement à l'oxygène ou un stade de peroxyde d'hydrogène, il permet d'améliorer à la fois la blancheur et les propriétés physiques, en solubilisant les métaux de transition. c) Entre deux stades tel que peroxyde et hydrosulfite, il permet d'éliminer l'étape de lavage en créant les conditions acidiques nécessaires à un traitement à l'hydrosulfite, et de détruire (par réduction) le peroxyde résiduaire, qui autrement consommerait l'hydrosulfite.

Dans le texte qui précède, on doit lire : SO2 ainsi que H2SO4.
