Hastings Igloo Hazards Tests for Small Explosive Charges

摘要

Full-scale field tests have been conducted to characterize the hazards to an exposed site when limited quantities of bulk explosives, positioned inside igloo magazines, are statically detonated. Specific test objectives were to (1) determine the explosive quantity which, when detonated inside a standard-size, earth-covered magazine, produces no significant external effect and (2) evaluate the dispersal of structure debris and measure external airblast for the range of explosive quantities for that marginally contained up to 68 Kg (150 lb). Test results in the form of overall structural response, airblast measurements and hazardous fragment distributions are provided for selected explosive charge weights from 5.4 Kg (12 lb) to 68 Kg (150 lb).
