When it comes to "shelf life," it must be first thought of by the date of production of the food. The meaning of the shelf life on the food label means "the date on which the food quality is guaranteed under the conditions specified on the label." However, it may be due to the premature deterioration of changing materials such as storage methods and environment. Therefore, food should be eaten as soon as possible before the expiration date. The shelf life of food is also the same as the "safety awareness" in the high-temperature and high-pressure petrochemical industry. When we first entered the factory and received safety training and education, we all had a strong sense of safety. However, with the passage of time, skillful operations, daily work face the same device, the same pipeline, the same equipment, or in a relatively long-term security environment, they gradually judge themselves to be eternal and safe. It has become a fluke, bold, paralyzed, and over time has formed a "zero probability" and "impossible" subconsciousness, resulting in a sense of safety fatigue. Therefore, the author believes that in day-to-day work, the emphasis on the reinforcement of employees' safety awareness is the most powerful guarantee for safety production to be “not overdue”.

"Liu Liu, did you go back with this old helmet? Haven't you got a new one?" "Master Li, I feel like I've lost it. It's a pity that I use it as a waste and take it home as a helmet for a motorcycle." "The shelf life of the helmet is six years. Your old helmet has passed the shelf life and cannot be used. Security can not be taken lightly." This is a dialogue between Master Lao and Apprentice Xiao Liu. After the shelf life of the helmet, if you continue to use, it is bound to pose a threat to safety. Therefore, the safe “shelf life” must be implemented in terms of concepts and items involving safe production.

How can security awareness be strengthened? From our staff itself will be the first "want me to safety" into "I want security." Thoroughly eliminate the sense of safety and fatigue, for example, before each device enters the device, look at the warning license plate “7 Thinks and 7 Don’ts” and reflect on whether or not your own safety measures are in place. Before entering the device inspection, check whether the H2S detector, intercom and other items are fully worn. Into the device inspection, up and down the stairs to support the stairs handles and so on. Taking "little things" as a "big thing" to do, we will grasp the "security awareness" and grasp "safety production" to go hand in hand, which is to make their own safety awareness "does not expire" to ensure the safety of the device the most powerful guarantee.
