Q: An Evaluation of the Fire & Explosion Hazards of Thermopolymers of Diene Hydrocarbons

This translation comprises both parts of a two-part study: Report 1. A Study of the Thermal Indications of the Fire and Explosion Hazards of Thermopolymers, by V. A. Shikhanov, N. A. Komarovsky, T. V. Kriger, et al., Production & Utilization of Elastomers , No. 8; 12-15 (1992). Report 2. A Study of the Critical Conditions of Spontaneous Combustion in Thermopolymers, by V. A. Shikhanov, N. A. Komarovsky, T. V. Kriger, et al., Production & Utilization of Elastomers No. 9; 9-11 (1992). English translation from Russian. The authors examined the spontaneous combustion hazards associated with a spontaneous polymerization which can occur in the processing equipment for diene thermoplastic elastomers (butadiene, isoprene, and butadiene-piperylene rubbers). Experimental data are provided from an oven-cube testing method. A chemical-structure criterion was evolved allowing to distinguish highly-hazardous elastomers from moderately hazardous ones. The study has special application to potential hazards of production wastes.

Q: A Consideration of the Safety of Screwless Terminals (Push-In Connections)

A Consideration of the Safety of Screwless Terminals, by Tadamichi Hijikata, Kunihiko Arai, Satoshi Otsuka, and Minoru Hara, Japanese Association of Fire Science and Engineering , Vol. 38, No. 6 (Whole No. 177), 19-22 (1988). English translation from Japanese. A study was made of a fire caused by resistive heating at a screwless (back-wire, push-in) connection on a wiring device. The safety of push-in connections is problematic, and an engineering study is used to show that screw-connected terminations are more reliable. Contact surface area is shown to be an important variable in establishing a reliable connection. This document also includes a shorter paper presenting a summary of the above study: Danger of Fire with Screwless Terminals, by Satoshi Otsuka, Proceedings from Presentations of Identification Science Research Papers.

Q: Combustion of Characteristics of 250 KG Aluminum Paste and Extinction Behavior

Combustion Characteristics of 250 kg Aluminum Paste and Extinction Behavior with the Use of Water, by Naochika Torikai, Takeshi Meguro, and Yoshitaka Kobayashi, Keikinzoku (J. Japan Institute of Light Metals) Vol. 30, No. 12, 754-760 (1980). English translation from the Japanese. The authors have carried out a series of studies concerning safety for aluminum paste fires and explosions and have reported on the behavior and burning characteristics of aluminum paste when heated, reactivity with water, acids and alkaline substances, combustion characteristics of aluminum pastes in commercial pails and the like. Combining the studies up to this point, the characteristics of the solvents were stronger than the characteristics of the metal powder, and we obtained results showing that we can assume that it is necessary to handle it as a solvent fire when there is a fire. Therefore, we used 250 kg of aluminum paste this time, and along with observing the state of combustion when this was strongly heated from the outside in air, we carried out experiments with the goal of confirming the safety when water was poured onto the aluminum paste at red heat. We have given consideration to "the safety of aluminum paste during fires," so we are reporting here.

Q: Reactivity of Aluminum Paste with Water, Acid and Alkali

Reactivity of Aluminum Paste with Water, Acid, and Alkali, by T. Meguro, N. Torikai, and Y. Kobayashi, Keikinzoku (J. Japan Institute of Light Metals) 29:6, 219-222 (1979). English translation from Japanese. This work relates to the safety of aluminum pastes contacting with water in transportation or on storage. Pastes containing aluminum powders 50 to 90 wt%, and stamped and atomized powders were tested. Hydrogen gas volume evolved in the reaction in a thermostat at 30 degrees C was measured as a function of reactivity. The aluminum pastes and stamped powder are free from the reaction with water. The atomized powder easily reacts. The aluminum pastes are also free from reactions with hydrochloric acid and sodium hydroxide solution at pH 2 to 11. Any indications of the dust explosion are unrecognized. The aluminum pastes seem to be quite safe for the reaction with water whereas this is not true of the atomized powder.

Q: Behavior and Combustion Properties when Aluminum Paste is Heated

Behavior and Combustion Properties when Aluminum Paste Is Heated, by T. Meguro, N. Torikai, and Y. Kobayashi, Y., Keikinzoku (J. Japan Institute of Light Metals) 29:5, 173-178 (1979). English translation from Japanese. Combustion tests were carried out on aluminum pastes containing 50 to 90 wt% aluminum powder and aluminum powders, stamped and atomized, to examine the safety of aluminum pastes on fire. The tests included heating up to 800 degrees C in an electric furnace, burning in a gas burner flame, and firing in a porcelain crucible by using a gas burner. Solvents in the pastes are only combustible and any indications of the dust explosion are unrecognized. Coagulation of the aluminum powders is found. Violent ignition takes place after combustion has completed in the crucible in which the stamped powder is filled. The aluminum pastes resemble petroleum in combustion properties.
