Integration of process safety engineering and fire protection engineering for better safety performance

Since the inception of the process industries, there have been a great number of process incidents causing significant loss of life and property damage. Even the establishment and implementation of a series of rigorous regulations has not prevented the occurrence of process incidents. In order to protect people, property and the environment a more robust safety program is needed and the safety performance of process industries must continue to improve. In this work, the common ground and the unique characteristics of process safety engineering (PSE) and fire protection engineering (FPE) is reviewed to demonstrate the potential benefits of unifying the two fields or improving the coordination between them to create a more robust safety program, thereby enhancing the safety performance of process industries. Recommendations are made to facilitate and encourage continued discussion and efforts toward the integration of process safety engineering and fire protection engineering.     

EMS与OSHMS的整合研究

近年来 ,在环境管理体系和职业安全健康管理体系的建立、认证和持续改进的实践中 ,企业、咨询与认证机构都发现 ,两体系独立建立、完善和持续改进 ,不断提升中 ,仍存在一些问题 ,人们提出 ,实现两大管理体系的整合 ,不仅有利于企业对环境管理和职业安全健康管理的资源共享 ,而且也是顺应国际认证发展的潮流。为此 ,笔者论述了两大管理体系整合的原因 ;讨论了整合的基本原则和难点 ;分析了两大管理体系整合的基本思路 ;研究了ESH整合型管理体系的实现过程。

One day is all it takes: circadian modulation of the retrieval of colour memories in honeybees

In this study, we examined how honeybees coped with successive tasks of colour discrimination with conflicting demands. Free-flying honeybees (Apis mellifera) were trained on tasks in which they had to choose one of three colours to obtain a reward of sugar water. In acquisition, the bees learned this task in about four trials of training. Colour memory was retained after 24-h delay in an unrewarded retention test. Integration experiments were then conducted in which the bees had to learn two successive tasks of colour discrimination with conflicting demands, task 1 for 20 trials and task 2 for ten trials. In task 1, one of three colours provided sugar water while the other two provided tap water, while in task 2 a different colour provided the reward. The bees were given unrewarded tests immediately after training on task 2 and then re-tested after 10 min, 22 h (circadian time of the start of task 1 training), or 24 h (circadian time of the end of task 2 training). Bees strongly preferred the rewarded colour for task 2 on immediate testing and after 10-min delay. After 22-h delay, they switched their preference to the rewarded colour for task 1. But after 24-h delay, the bees again strongly preferred the rewarded colour for task 2. Further tests at a number of delays between 0 and 22 h revealed a sigmoidal pattern of rise in the preference for the task 1 colour. We conclude that circadian time modulates the retrieval of colour memories in honeybees, even when all the training took place in a single day.
