I will give conjecture and a brief example from my experience in an attempt to analyze times when humans lose control and explode. One of the points that give rise to danger when dealing with steam is when there exists no pressure relief valve or when it malfunctions. . A similar danger may exist when humans try to bottle up and contain emotions that may produce pressure when not vented.
Just as steam relief valves vent extra pressure, humans have developed means to “let off steam. Two that come to mind are focused physical exertion to bleed off bottled up energy or calmness exercises that are designed to turn down the internal heat that builds stress. When these exercises are not in place or somehow not working, the danger of a human explosion comes to bear.
Like steam pipes that have gauges reading pressure and providing alerts that should be heeded, humans would do well to monitor their state in order to intervene upon an approaching angry outburst. Unfortunately human gauges are not as easy to read as mechanical ones. But usually with practice and helpful feedback, it may be possible to detect impending problems based upon precursor events unfolding. Of course, this assumes that a person is looking to curb violent outbursts. If they are not, it may pay those nearby to attend to reading the signs of looming pressure buildup so they may take appropriate evasive maneuvers. I hope that if I was near a pressure cooker that was showing sign s of going off, I could prepare an exit.
On incident that comes to mind, when I took this action occurred during a bout of cabin fever while living in rural Arkansas. I was not aware that being cooped up all winter can place inevitable pressure on human relations. I, Willow and her two kids had spent the whole winter cooped up with no electricity, no indoor plumbing, nor running water, and our only source of heat was a wood cook stove. There was certain romantic charm spending a winter in this gorgeous natural setting. However, probably neither of us regularly had pressure outlets, nor were we familiar with detecting coming flare-ups. One morning the pressure erupted.
My custom was to rise early, make a fire, and prepare a pot of coffee. Usually, I would sit enjoying my coffee, while waiting for Willow to arise and have breakfast and launch the kids off to school. One morning, Willow awoke in an agitated state. A heated discussion ensued. I remained in my chair holding my cup. At some point Willow placed her hand on my shoulder and started shaking it to make a point. She was unaware that her jerking my shoulder was spilling hot coffee on my wrist. I was suffering burns. When I exploded, I flicked the remainder of my cup up at her. It covered the front of her blouse. Fortunately she was not burned, but her pressure also reached explosive state.
Willow went over to the stove, picked up the whole pot of coffee and headed back to my chair. I saw her coming and detected a fit of anger in her stance. I sensed danger and automatically rose up and knocked the pot out of her hands and onto the floor. I rushed to her side and grabbed her in a bear hug, lifted her off the floor and carried her outside. There I remained in an embrace afraid if I let her go , we may start swinging at each other. In a few moments, pressure seemed eased, and I asked,, “If I let you go, can I go inside and get a few things, so I can get away for a day or so?” She agreed. Hastily, I gathered a small pack and walked down the road. Besides the small burns on my wrist, injury had been avoided. We both learned the necessity of not letting pressures build to unsafe levels. To this day, memory of that event provides me with an example of what may occur should I not attend to my pressure gauges.
