Immediately after one sees the first flash of intense heat and light of the developing nuclear fireball, one should stop, get under some cover and drop/duck to the ground. Stay calm, check for injury, check weapons and equipment damage, and prepare to continue the mission. Remain facedown until the blast wave passes and debris stops falling. Protect exposed skin from heat by putting hands and arms under or near the body and keeping the helmet on. A log, a large rock, or any depression in the earth's surface provides some protection. Procedure During a surprise nuclear attack ĭropping immediately and covering exposed skin provide protection against blast and thermal effects. In these analogously powerful events, Drop, Cover and Hold on likewise prevents injury or death if no other safety measures are taken.Īs a countermeasure to the lethal effects of nuclear explosions, Duck and Cover is effective in both the event of a surprise nuclear attack, and during a nuclear attack of which the public has received some warning, which would likely be about a few minutes prior to the nuclear weapon arriving. Maneuvers similar, but not identical, to Duck and Cover are also taught as the response to other sudden destructive events, such as an earthquake or tornado, in the comparable situation where preventive emergency evacuation is similarly not an option, again, due to time constraints. The countermeasure is intended as an alternative to the more effective target/citywide emergency evacuation when these crisis relocation programs would not be possible due to travel and time constraints. In the most literal interpretation, the focus of the maneuver is primarily on protective actions one can take during the first few crucial seconds-to-minutes after the event, while the film of the same name and a full encompassing of the advice also cater to providing protection up to weeks after the event. Ducking and covering is useful in offering a degree of protection to personnel located outside the radius of the nuclear fireball but still within sufficient range of the nuclear explosion that standing upright and uncovered is likely to cause serious injury or death. ' Duck and cover' is a method of personal protection against the effects of a nuclear explosion. Duck and cover drill in a sсhool in Brooklyn in 1962
