Operational Procedures: Physical Safety
Since we have considered the electrical dangers a technician might face, we must also consider the physical dangers. As information technology technicians, we often are involved in the “rollout” and replacement of existing systems, and in moving equipment from one office area to another. In this portion of our jobs, we often have to move hundreds of computers. Remember, the number one cause of injury for computer technicians is lifting items that are too heavy for us. A couple of rules of thumb to prevent injury: Do not lift anything over 25 percent of your own weight without assistance. Second, remember to always lift with your legs, not your back. If you follow these two simple rules, you can avoid the most common injuries in the workplace.
由於我們已經考慮了技術人員可能面臨的電氣危險，因此我們還必須考慮物理危險。作為信息技術人員，我們經常參與“部署”和替換現有系統，以及將設備從一個辦公區域轉移到另一個辦公區域。在這部分工作中，我們經常不得不移動數百台計算機。請記住，計算機技術人員受傷的首要原因是提起對我們來說太重的物品。防止受傷的一些經驗法則：不要在沒有幫助的情況下舉起超過自身體重25％的東西。其次，請記住始終抬起雙腿，而不是背部。如果遵循這兩個簡單規則，則可以避免在工作場所中最常見的傷害。
Another area of concern is our impatience. Often when we go to work on a computer, we first turn off the machine and then open it up. Many of us forget that the computer may have been on and running for the past several days or weeks, building up an enormous amount of heat that can cause burns. It is a good idea to wait at least 15 minutes before touching items at the workstation, such as a laser printer’s fuser, the central processing unit (CPU) of the computer, or the power supply of the computer. These areas tend to generate the most heat and need time to dissipate the heat prior to maintenance.
另一個值得關注的領域是我們的耐心。通常，當我們在計算機上工作時，首先關閉機器，然後再打開它。我們中的許多人都忘記了計算機可能已經在過去的幾天或幾週內開機並運行，從而積聚了大量的熱量，可能引起灼傷。最好等待至少15分鐘，然後再觸摸工作站上的物品，例如激光打印機的定影器，計算機的中央處理器（CPU）或計算機的電源。這些區域往往會產生最多的熱量，並且在維護之前需要花費一定時間消散熱量。
Finally, we must be wary of how we route cables, and must practice proper cable management. Do not run cables in the walkways or through places where employees may trip over them. If a worker trips on the cord, not only will the worker get hurt, but the workstation itself could be pulled off the desk and damaged. Place the computer and cables in a place where adequate air flow can occur; otherwise, the computer may overheat and have issues functioning. Finally, always remember to check local regulations when installing new network cables. Some areas require certain licenses or certifications, such as an electrician’s license, to run network cables. Also, you will need to install plenum-rated cables if you are running them in areas such as the ceiling, where ventilation systems are found.
最後，我們必須警惕如何佈設電纜，並且必須進行適當的電纜管理。請勿在走道或員工可能絆倒的地方穿過電纜。如果工人用電線絆倒，不僅會受傷，而且工作站本身可能會從桌子上拉下來並損壞。將計算機和電纜放置在可產生足夠空氣流通的地方；否則，計算機可能會過熱並出現問題。最後，在安裝新的網絡電纜時，切記要檢查當地法規。有些地區需要某些許可證或證明（例如電工許可證）才能運行網絡電纜。另外，如果要在通風良好的區域（例如天花板）上鋪設增壓電纜，則需要安裝增壓電纜。
So, why is cable management so important? Well, imagine your boss just told you that her workstation lost its connection to the network. You run down to the server room to see if you can troubleshoot her connection. You look first to check if her cable is plugged in, but you find the mess of cables below. How do you determine which is your boss’ connection? This mess causes issues with ventilation, cooling, and more importantly issues when trying to troubleshoot. Always run the cabling with proper cable management techniques and label the cables to assist you in the future during troubleshooting.
那麼，為什麼電纜管理如此重要？好吧，想像一下您的老闆剛剛告訴您她的工作站失去了與網絡的連接。您跑到服務器機房查看是否可以解決她的連接故障。您首先要檢查她的電纜是否已插入，但在下面發現電纜亂七八糟。您如何確定老闆的聯繫方式？這種混亂會導致通風，冷卻問題，更重要的是，嘗試進行故障排除時會出現問題。始終使用適當的電纜管理技術來佈線，並標記電纜，以在將來進行故障排除時為您提供幫助。
