Protection Against Flying Glass. In Great Britain serious casualties and delay* in production have been caused by flying glass—all types of glass are likely to be broken by intense blast effects. Breakage of glass cannot be prevented except by removal or possibly by complete blocking of the window opening. WHERE GLASB CANNOT BE REMOVED THE AIM SHOULD BE TO PREVENT FRAGMENTS FROM FLYING AND TO MAINTAIN WEATHERPROOF CONDITIONS. Windows should be treated in order of urgency. The various ways of covering glass with the aim of minimising the effects of blast have been examined by the British Standard Specification Committee. One method recommended takes the form of materials fixed to the glass with a special adhesive as an all-over coating or in strips. It must be emphasised that the aim of this treatment is to prevent glass from flying into small dangerous splinters, it does not prevent breakage. PANES OF GLASS PROPERLY COVERED BY THE " BLINTZ " TREATMENT WILL REMAIN IN PLACE UNDER MILD BLASTS EVEN IF BADLY CRACKED. In deciding upon a suitable treatment to reduce the risks of glass splintering the important requirements are:— (a) The fabric must possess considerable tensile strength. (b) The fabric must adhere strongly to the glass. . (c) Both the fabric and the special adhesive should retain their properties for a reasonable length of time under exposure on the inside of the window. Although a greater degree of protection is obtained by applying the treatment all over the glass, strips of strong material spaced apart can nevertheless be used with good effect, but the closer the spacing the better. It is advisable, although not essential, that the adhesive treatment should extend beyond the glass over the window frame, and, of course, additional resistance to splintering is obtained by coating the outside as well as the inside of the glass, but when applied outside the treatment must be protected with a coating of special ANVIL waterproof eolution.
