    CHEMICAL HYGIENE PLAN AND HAZARDOUS MATERIALS SAFETY MANUAL FOR LABORATORIES This is the Chemical Hygiene Plan specific to the following areas: Laboratory name or room number(s): ___________________________________ Building: __________________________________________________________ Supervisor: _______________________________________________________ Department: _______________________________________________________ Telephone numbers 911 for Emergency and urgent consultation 48221 Police business line 46919 Fire Dept business line 46371 Radiological and Environmental Management Revisied on: Enter a revision date here. All laboratory chemical use areas must maintain a work-area specific Chemical Hygiene Plan which conforms to the requirements of the OSHA Laboraotry Standard 29 CFR 19190.1450. Purdue University laboratories may use this document as a starting point for creating their work area specific CHP. Minimally this cover page is to be edited for work area specificity (non-West Lafayette laboratories are to place their own emergency, fire, and police telephone numbers in the space above) AND appendix K must be completed. This instruction and information box should remain. This model CHP is version 2010A; updates are to be found at www.purdue.edu/rem This page intentionally blank. PURDUE CHEMICAL HYGIENE PLAN AWARENESS CERTIFICATION For CHP of: ______________________________ Professor, building, rooms The Occupational Safety and Health Administration (OSHA) requires that laboratory employees be made aware of the Chemical Hygiene Plan at their place of employment (29 CFR 1910.1450). The Purdue University Chemical Hygiene Plan and Hazardous Materials Safety Manual serves as the written Chemical Hygiene Plan (CHP) for laboratories using chemicals at Purdue University. The CHP is a regular, continuing effort, not a standby or short term activity. Departments, divisions, sections, or other work units engaged in laboratory work whose hazards are not sufficiently covered in this written manual must customize it by adding their own sections as appropriate (e.g.

ENMC-2 SENSITIVITY AND DETONATION PARAMETERS OF 4, 6-DIAZIDO-N-NITRO-1, 3, 5-TRIAZIN-2-AMINE Tomáš Musil*, Robert Matyáš*, Ondřej Němec*, Martin Künze* Abstract Highly dense nitrogen-rich compounds are potential high performance energetic materials for use in industrial scene or military. 4,6-Diazido-N-nitro-1,3,5-triazin-2- amine (DANT) is relatively a new substance on which characterization and detonation parameters were tested. The sensitivity of DANT to impact, friction and electric discharge was also determined. Sensitivity to impact is between PETN and RDX, sensitivity to friction is higher as PETN. DANT´s relative strength is 108 % of TNT. We also calculated and measured detonation parameters such as pressure and detonation velocity. Theoretical detonation parameters are 8 205 m.s-1 and 30.3 GPa. Temperature of autoignition is 156 °C. Keywords: 4,6-Diazido-N-nitro-1,3,5-triazin-2-amine; DANT, detonation parameters, sensitivity * Institute of Energetic Materials, Faculty of Chemical Technology, University of Pardubice, Studentska 95, 532 10 Pardubice, Czech Republic.

Introduction 4,6-Diazido-N-nitro-1,3,5-triazin-2-amine (DANT, see scheme 1) – this relatively simple molecule was first reported only four years ago by Fronabarger et al. [1]. The more extensive study of this molecule focused on its synthesis, analysis, structure and its sensitivity to mechanical stimuli was published recently by us [2].

  • Study on the Formation and the Decomposition of Agn3 and A
    Study on the formation and the decomposition of AgN3 and a hypothetical compound ReN3 by using density functional calculations. G. Soto. Universidad Nacional Autónoma de México, Centro de Nanociencias y Nanotecnología Km 107 carretera Tijuana-Ensenada, Ensenada Baja California, México. Corresponding Author: G. Soto. CNyN-UNAM P.O. Box 439036, San Ysidro, CA 92143-9036, USA Tel: +52+646+1744602, Fax: +52+646+1744603 E-Mail: [email protected] Abstract We present a comparative study between ReN3 and AgN3 by using density functional theory. The ReN3 is a hypothetical compound proposed by us to interpret the Re to Re interplanar spacing of thin films grown by sputtering. Both, the AgN3 as the ReN3, are calculated as positive enthalpy compounds. The enthalpy might give a clue about the spontaneous decomposition of the solid form, but it cannot be interpreted as a restriction of its synthesizability. As from the calculated total-energy, we discuss the route for the formation of AgN3 starting from atomic species in aqueous solution. We propose that their synthesizability is conditioned by the energy of free nitrogen atoms, and the kinetics of reaction. We conclude that the intrinsic stability of a certain atomic arrangement depends only of the equilibrium of atomic forces, and not from the energy value associated with that structure. 1 1. Introduction Predicting new solids based solely on computer calculations is one of the main challenges of materials science. Achieving this would mean a giant step forward as it would save many hours of fruitless efforts. Although there has been significant progress[1], it is still early to sing praises.
