At Shiftwork Solutions, safety concerns are definitely something we have to pay attention to. We keep abreast of safety research as it applies to shiftwork and bring that knowledge to the table when working with companies.
Over the years, there are a few standard issues that come up. I'd like to cover those now. I also would like to bring up a few safety practices that I have seen at other sites which lent themselves well to the establishment of a strong safety program.
As they occur to me...
- As you age, your ability to get enough sleep in one session diminishes. You main sleep period will shorten and you will find the need to nap during the day goes up.
- Shift length plays a very small role in how much sleep you get in a day. A person on an 8-hour shift may get a few more minutes of sleep when compared to a person on a 12-hour shift. However, we get a great deal more sleep on days that we don't come in to work; about 60 to 90 minutes more. So, its better to work a shift with more days off. This usually means longer shifts.
- The older you get, the harder it is to work more days in a row. It is also harder to adjust to different shifts - a problem that is growing smaller as more and more companies get away from rotating shifts.
- You need about 8-hours of sleep a day.
- When people become sleepy, they care less about doing a good job. This will start to show up in small ways as people begin to take short-cuts in their work. Short-cuts can lead to quality, production and safety problems if left unchecked.
- Naps are a great investment. A short, 10-15 minute nap can make you alert for the next several hours. The problem with napping at work is that we don't fall asleep instantly and, we need to deal with sleep inertia - the grogginess we feel after waking.
- A workforce that starts its day shift at 7:00 am will get about 20 more minutes per night than a workforce that starts its day shift at 6:00 am.
- People learn by (1) doing the task or (2) reading about the task or (3) watching the task being done or (4) conceptually imagining how the task might be done. Apply this to safety at your site. Don't just rely on one method of making people "safety aware."
- At one site I worked at, every time a group of people got together for a meeting, the first thing they did was ask "Who wants to tell us about a task they have coming up?" The volunteer might say, "I am going to the warehouse to pick up some spare parts." Next, every single member would have to point out a safety item dealing with that task. For example: "Make sure to wear your safety belt on the drive over" or "When you get there, make sure you wear the proper protective equipment" or "Check the pressure on your tires before the drive." As you can see, no issue is too small and there are lots of issues. This exercise forces everyone to "think" for a moment. I really like this idea.
- At another site, you never said "good-bye" or "I'll see you around." The parting comment was always, "Work Safe."
- I was at a mine where there were nearly 100 huge trucks moving around the site at any one time. One thing we did was track accidents by time of the week. Every week we could see which hour had the most safety incidences. When that hour came up the following week, we would go out on the general communication system and say, "You are now entering the most dangerous hour of the week." That hour nearly always became one of the safest hours of that week.
- When I go to a site, I sometimes leave off my safety glasses or ear plugs and see how the workforce responds. When I get stopped right away by an hourly guy telling me to put on glasses, I know I am at a well run plant. A plant that has a strong safety program is typically strong at a lot of other things as well.
