Production Technology [Weekly Topic]: Accident Analysis (10-11-22~28)
Thread Content
In a workshop of a chemical plant, worker Zhang was conducting inspections at the production site. When he was inspecting the tank area near the factory gate, he heard a announcement over the speakers in the control room asking him to return the call. Zhang quickly went to the security guard at the entrance to find a phone. Since the booth was completely transparent, Zhang got his right hand pierced by the broken glass when he pushed the door open. Diagnosis: rupture of the tendon in the right ring finger, and laceration of the skin on the right hand. It has been determined to be a disability grade of 7. Please analyze the direct and indirect causes of the accident. What are the violations committed by the workers? How can we prevent similar accidents from happening again? Notes: 1.

The direct cause of this accident was Mr. Zhang’s own carelessness, while the indirect cause was the lack of safety signs in the company. 2. Frequent absence from one’s post, and failure to wear safety gear during working hours. 3. The identification must be clear and complete, with safety education as well as training on job responsibilities provided. :)
The responsibilities for this issue are as follows: 1. The security staff failed to clean up and replace the broken glass in a timely manner, failing to carry out proper on-site management； 2. Even if it’s not possible to replace the broken glass right away, warning measures should still be taken ； 3. Lao Zhang works in a hurry and doesn’t pay attention to observing things carefully ； 4. Lao Zhang has a poor awareness of safety precautions ； 5. Neither the gatekeeper nor Lao Zhang complied with the safety requirement of “three no-harms,” which constitutes a liability accident.
1. Immediate cause: Accidental contact with broken glass； Indirect cause: Broken glass, no warning signs. 2. No personal protective equipment was worn ； Safety hazards were not eliminated in a timely manner, and there are no relevant warning signs ； Job swapping (although it’s for work). 3. Strengthen employee safety education ； Eliminate safety hazards in a timely manner ； Hazards should be warned about.
Wear a safety helmet and protective gear during inspections. One must have a high sense of responsibility and not leave one’s post without permission. Those engaged in chemical production must always keep in mind the principle of ’safety first, prevention foremost’. They must never rely on luck or become complacent at any time; they should abide by rules and regulations, transforming the passive attitude of ’I need to be safe’ into an active one of ’I want to be safe’. Only in this way can chemical enterprises develop safely and harmoniously, and individuals can live a safe and healthy life! It is hoped that this person will take this as a lesson and always keep the ‘safety’ aspect in mind.
Reply to 1# shmily327: Safety glass should be used for the glass in the production facility area. Warning labels such as \"Be careful not to damage\" should be attached to the transparent glass.
Immediate cause: 1. The glass on the door was broken； 2. Staff violated the safety operating procedures and went to the security office to use a phone. Indirect causes: 1. After the glass on the door broke, the security guard failed to inform the maintenance department in a timely manner, or the maintenance department failed to carry out repairs promptly ； 2. Failure to use safety warning signs and other explanatory markings ； 3. Inadequate safety education ； 4. The workers lack mental resilience and tend to act in a panicked manner. To prevent similar accidents from occurring, first, strengthen safety education and training by employing employees with good psychological resilience ； Second, establish comprehensive operating procedures and ensure that employees follow them strictly ； Third, the maintenance department should establish a regular inspection and maintenance system to ensure that the equipment remains in good condition ； Fourth, those areas that cannot be repaired in a timely manner and pose safety hazards. All personnel should be informed, temporary protective measures should be taken, and safety warning signs or barriers should be installed in the surrounding area. And carry out repairs promptly once the conditions for maintenance are available.
No walkie-talkie was carried, so I lost my calm in an emergency!

Action: Strengthen education on the necessity of checking, and post warning signs in areas with potential safety hazards (such as transparent glass)
Come and take a look at the answer:):victory:
Immediate cause: There were no warnings or notes attached to the kiosk indicating attention to the glass, which made it easy for people to get scratched by the transparent glass when they were nervous； Indirect cause: The factory failed to carry out its duties properly; the personnel on duty during inspections should not be asked to answer calls or engage in any other activities unrelated to the inspections ； Moreover, the staff themselves lack the awareness that they should not engage in matters unrelated to their work during working hours, and end up leaving their posts. The above-mentioned reasons led to the accident.
