Emergency response to chemical accidents is a complex and high-risk task, with the personal safety of rescuers being the foundation of this entire system. From the initial detection of an incident, through the rescue process, to post-incident monitoring, ensuring proper protection for those involved is crucial. In fact, personal protective measures in chemical accident responses serve as the final line of defense for workplace safety and the lifeline for rescuers. These measures directly impact the lives of the workers and determine the success or failure of the operation. Therefore, it's essential to conduct scientific analysis and continuous improvement to enhance the effectiveness of personal protection during these critical situations.
**I. Current Status of Personal Protection in Chemical Rescue**
With the advancement of technology and the growing awareness of safety, both organizations and individuals have significantly increased their investment in protective equipment and training. As a result, the capabilities of rescue teams have improved considerably. However, despite these advancements, there are still vulnerabilities in the system.
(a) Subjective Factors: Many personnel lack a full understanding of the dangers involved in chemical incidents, leading to weak safety awareness and inadequate protocols. For example, in April 2007, a bromine leak occurred at a service area on the Shanghai-Hangzhou Expressway. Without any protective gear, rescuers carried out decontamination, resulting in seven people being poisoned. Additionally, many rescue teams are not professionally trained, and they often neglect proper protective procedures. The management and maintenance of protective equipment are also lacking, reducing its effectiveness.
(b) Objective Challenges: Accurately assessing the on-site situation is difficult due to unpredictable chemical reactions, especially after fires. Information about the chemicals may be incomplete or false, making it hard to implement effective protection. Poor communication between units further hinders the sharing of critical information and best practices, limiting the overall improvement of protective strategies.
**II. Building an Effective Personal Protection System**
(I) Enhance Safety Awareness and Strengthen Protocols: It's important to raise awareness about the risks involved in chemical rescue and the necessity of proper protection. Establishing professional rescue teams and increasing funding for protective equipment are key steps. Also, integrating safety into every aspect of the rescue process is vital.
(b) Increase Training and Practical Drills: Chemical rescue requires specialized skills. Rescuers must understand the properties of different chemicals and how to use protective equipment effectively. Regular theoretical and practical training should be conducted, including simulation exercises that focus on selecting the right protective gear based on environmental conditions.
(3) Optimize Equipment Management: Modern information systems can improve coordination between units, enabling better resource sharing and more efficient equipment allocation. Proper management of protective gear, including maintenance and staff health checks, ensures that all equipment remains functional and reliable.
(D) Develop Clear Protective Procedures: Standardized protocols should be established based on the type of equipment and the level of danger. High-risk scenarios require stricter and more precise protective measures. This helps prevent over- or under-protection, which could harm rescuers or hinder operations.
(5) Adjust Protection Levels Dynamically: Protection levels should not be static. Initially, high-level protection might be necessary, but as the situation stabilizes, it can be reduced. However, when the risk is uncertain, rescuers should maintain a higher level of protection. Correct identification of hazards and appropriate selection of protective gear are essential. Factors such as chemical properties, equipment durability, and user comfort must all be considered.
Regular drills and strict checks on protective gear ensure that the safety barrier remains strong.
**III. Evaluate and Improve Protection Effectiveness**
After each rescue, a thorough review should be conducted. This includes analyzing on-site conditions, evaluating the performance of protective equipment, and documenting any injuries or issues. Detailed investigations help identify lessons learned and improve future responses. Collaboration between units and factories is also important to share experiences and enhance overall rescue capabilities.
