Le présent document fournit des principes et des exigences pour la manutention et le stockage en toute sécurité des granulés de bois dans les applications résidentielles et autres applications à petite échelle. Il couvre la chaîne d'approvisionnement à partir du chargement du camion de livraison, les exigences applicables aux camions de livraison, les jonctions avec le silo de l'utilisateur final et le processus de livraison. Il couvre également la conception et la construction des installations de stockage des granulés. Le présent document traite des risques d'incendie, d'explosion de poussières, de dégagement gazeux, de diminution de la teneur en oxygène, de dommages sur les appareils et bâtiments dus au gonflement des granulés, et des autres risques pour la santé. Il s'applique aux granulés de bois conformément à l'ISO 17225-2.

Trdna biogoriva - Varnost peletov trdnega biogoriva - Varno ravnanje in shranjevanje lesnih peletov za uporabo v stanovanjskih in drugih manjših napravah (ISO 20023:2018)

Ta mednarodni standard podaja načela in zahteve za varno ravnanje ter shranjevanje lesnih peletov za uporabo v stanovanjskih in drugih manjših napravah. Obravnava dobavno verigo od končnega mesta natovarjanja razsutega tovora do skladiščenja pri končnem uporabniku in določa posebne zahteve za prevoz razsutega tovora. Obravnava tudi zasnovo in konstrukcijo sistemov za shranjevanje peletov. Ta standard obravnava nevarnosti nastanka požarov, eksplozije prahu in hlapov organskih spojin ter druga tveganja za zdravje. Uporablja se za lesne pelete v skladu s standardom ISO 17225-2.
