core.ac.uk2. Explosions and blast waves 2.1 Ideal blast wave characteristics An explosion can be defined as a very fast chemical reaction involving a solid, dust or gas, during which a rapid release of hot gases and energy takes place. The phenomenon lasts only some milliseconds and it results in the production of very high temperatures and pressures.
Explosions and Blast Injuries
www.cdc.govPrimary blast waves can cause concussions or mild traumatic brain injury (MTBI) without a direct blow to the head. Consider the proximity of the victim to the blast particularly when given complaints of headache, fatigue, poor concentration, lethargy, depression, anxiety, insomnia, or other constitutional symptoms. The symptoms of
BLAST RESISTANT BUILDING DESIGN
www.iitk.ac.inThe target of blast resistant building design philosophy is minimizing the consequences to the structure and its inhabitants in the event of an explosion. A primary requirement is the prevention of catastrophic failure of the entire structure or large portions of it. It is also necessary to minimize the effects of blast waves transmitted into the
PROCEDURES FOR BLASTING
www.dot.ny.govwaves. 6. Misfires Misfires happen when a loaded hole, portion of a loaded hole, or several loaded holes fail to detonate during a blast. Misfires can be caused by failure of the detonation system or by explosive column cutoffs. Sometimes it is apparent immediately after a blast that a misfire has occurred.

WHAT IF YOU ARE NEAR THE BLAST WHEN IT OCCURS?
www.co.monmouth.nj.usRemain flat until the heat and two shock waves have passed (CDC, 2011). If you are outside when the blast occurs: Find something to cover your mouth and nose, such as a scarf, handkerchief, or other cloth. Your priority is to remove your clothing since it …

ntrs.nasa.govtherefore limited to impacts near the shore, and even in these cases the air blast, fireball, and possible ejection of sediment in shallow water areas may exceed the damage from the wave. The airbursts modeled, most of which assumed an explosion altitude of 10 km, produced a wave from blast over-pressure.
