How do you respond to a home explosion?
Explosion in the home Warn everyone.
Extinguish small fires if safe..
What are the effects of an explosion?
Direct, Primary Effects The main direct, primary effect to humans from an explosion is the sudden increase in pressure that occurs as a blast wave passes. It can cause injury to pressure- sensitive human organs, such as ears and lungs.
How many PSI can kill you?
The threshold value for lung damage is 12 psi and fatal effect is 40 psi (Glover, 2002). At a pressure of about 35 kilopascals (5 psi), the human eardrum may rupture. With an overpressure of 100 kPa (14 PSI) almost all eardrums will be ruptured.
Can an explosion cause a concussion?
Primary 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.
What does a shockwave do to your body?
Air-filled organs, including lungs, the GI tract and middle ear, are especially affected. The blast wave energy moves through the torso to the brain. This can potentially cause damage to tiny cerebral blood vessels, stretching and damaging neural cells in the brain.
What is blast lung?
“Blast lung” is a clinical diagnosis and is characterized as respiratory difficulty and hypoxia without obvious external injury to the chest. It may be complicated by pneumothoraces and air emboli and may be associated with multiple other injuries.
How far away from a nuclear bomb is safe?
Death is highly likely and radiation poisoning is almost certain if one is caught in the open with no terrain or building masking effects within a radius of 0–3 km from a 1 megaton airburst, and the 50% chance of death from the blast extends out to ~8 km from the same 1 megaton atmospheric explosion.
How long after a nuclear bomb is it safe?
The US Department of Health and Human Services recommends staying indoors for at least 24 hours in the event of a nuclear explosion. After 48 hours, the exposure rate from a 10-kiloton explosion (the type that might damage but not destroy a city) goes down to just 1%.
How do you die from an explosion?
Blast lung refers to severe pulmonary contusion, bleeding or swelling with damage to alveoli and blood vessels, or a combination of these. It is the most common cause of death among people who initially survive an explosion.
What do you do in case of an explosion?
During an ExplosionGet under a sturdy table or desk if things are falling around you. … Do not use elevators.Stay low if there is smoke. … Check for fire and other hazards.Once you are out, do not stand in front of windows, glass doors or other potentially hazardous areas.More items…•
At what psi of blast pressure from an explosion does lung collapse or damage occur?
Pulmonary damage occurs in 50% of victims exposed to 500 kPa (72.5 psi), whereas intestinal perforation occurs with much higher pressures. Exposure to pressure levels greater than 550 kPa (79.8 psi) is lethal in more than 50% of cases (Figure 7-2 and Figure 7-3). terrorist bombings: how can we cope?
What is blast injury?
A blast injury. is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. Blast injuries range from internal organ injuries, including lung and traumatic brain injury (TBI), to extremity injuries, burns, hearing, and vision injuries.
