<p>I have been asked to reply on behalf of the Department for Work and Pensions.</p><p>The risk of inhalation of asbestos fibres from a Second World War gas mask during a demonstration is dependant on the condition of the mask and how it is demonstrated. The Health and Safety Executive's assessment is that the risk of inhaling any asbestos fibres during the demonstration of Second World War gas masks in good condition is low. Nevertheless, if the mask is damaged or deteriorating there is an increased risk that asbestos fibres will be released. As all these gas masks are old, and assessing the condition of the filter is not straightforward, the Health and Safety Executive's advice is that it is not appropriate for children or teachers to handle for demonstration purposes any Second World War gas mask that could contain asbestos.</p>
