Facing danger controllability

Combustion is a fascinating reaction from the gentle light of a candle, to the comfort of the hearth, to the welcoming warmth of a campfire. But these are cases where combustion is controlled. In the cases of uncontrolled combustion, the fascination turns to fear, primal and pure. Thankfully, there are those who routinely face this fear to protect others from the danger. A brief consideration of combustion chemistry hints at the magnitude of their challenge. 

Excessive absorption results in paraesthesiae (face and tongue), anxiety, tremors and even convulsions. The latter are very dangerous, are followed by respiratory depression and may require diazepam or thiopental for control. Cardiovascular collapse and respiratory failure occur with higher plasma concentrations of the local anaesthetic and is caused by direct myocardial depression compounded by hypoxia associated with convulsions. Cardiopulmonary resuscitation must be started immediately. 

Fear is a strong and depressed emotional state which individuals or groups felt deeply in danger of real or imagined. It often manifests as nervous, fear, inability to concentrate, mind going blank, and inability to correctly judge or control behavior. Fear is an innate emotional response of all animal including human. Fear is emotional reaction to an expected to be hurt or unpleasant when face stressors, which usually cause avoidance behavior. 

Mine gas is one of the important hidden trouble to influence coal mine safety production (Shi et al., 2006), the abnormal gas emission will usually lead to coal mine gas accident. Gas emission is affected by many factors (Zhu et al., 2007 Guo et al., 2009 He et al., 2008), the judgment of abnormal gas emission is not only important to the real-time monitor of the gas concentration (Zhang et al., 2012), but also important to the discrimination of the reason of abnormal gas emission. Therefore, the dynamic evaluation of gas emission hazard danger level combined with gas monitoring data plays an important role on gas prevention and gas disaster control when it does dynamic early-warning of coal face gas emission (Lv et al., 2006 Gong et al., 2012). 

A clause or provision in a life insurance or accident policy whereby the company agrees to pay the stated multiple (i.e., double, even triple indemnity is available) of the face amount in the contract in cases of accidental death. An accidental death is considered a death that is neither intentionally caused by a human being, such as murder or suicide, nor from natural causes, such as cancer or heart disease. In 2004, 4.67 percent of all deaths in the United States were declared accidental by the Centers for Disease Control and Prevention (CDC). Double-indemnity clauses are therefore usually relatively economical and often highly marketed, especially to people over 45 and under 60. Children and people in dangerous jobs, such as heavy construction, are the exceptions.
