comment puis-je fonctionner en toute sécurité et de maintenir une lampe à alcool?
Cette question est pour l'école secondaire et les professeurs de chimie au collège. Je possède maintenant un verre de type alcool à facettes lampe avec couvercle en métal attachée par une chaîne. La dernière fois que j'ai utilisé une de ces était de retour dans la chimie de première année au collège. En ce moment j'ai l'intention d'être avec l'une de ces lampes pour lapidaire (cabbing) des procédures impliquant la cire dopping. En tant qu'ingénieur, j'ai maintenant mis au point un sujet en bonne santé à l'utilisation de matériel potentiellement dangereux et j'ai maintenant besoin d'un enseignant expérimenté de me dire une fois de plus ce que je dois ont appris la première fois, mais n'a pas. La question que je pose est la suivante: quelles sont les principales choses à faire et ne pas vers l'exploitation, l'entretien sécuritaire et le stockage d'une lampe à alcool?
Alcool brûleurs ou des lampes à alcool sont notoirement dangereux. La meilleure façon de la maintenir autour est sans alcool dedans. Le risque majeur est le dispositif de basculement et la diffusion de l'alcool enflammé partout. Caroline du Nord ne permet pas l'utilisation de brûleurs à alcool dans les écoles secondaires. Mon père gemmes taillées professionnelle (nous possédons toujours le rocher de la famille et des affaires boutique de pierres précieuses), et il serait d'utiliser un portable * torche à propane pour faire fondre la cire. Oui, il devient plus chaud, mais vous avez plus de contrôle sur la flamme, et il ya moins de danger en général. * Comme celui-ci de Lowes: 20torch% http://www.lowes.com/pd_148755-13877-309272_0_?productId=3130885&Ntt=plumbing & Ntk i_products = & pl = 1 & currentURL = / pl__0__s newSearch = true $ Ntt = 20torch% de plomberie y $ =? 0 $ x = 0
