Orient your friends and family about your composting activities.
Getting your family and friends involved or at least amply oriented will help you be able to relay your activities to them effectively. It will also help them become aware of certain things or objects you are using in the backyard (in cases where you do your compost heaps in the backyard), and will not be inclined to hit themselves with it while taking a leisure stroll.
Keep the compost aerated
The danger to compost is when it loses air and becomes more poisonous to the soil than helpful. Make sure that even when your compost heap is in a closed bin, there is still more than enough air for it to continue circulating. The aeration process helps enhance the composting process, and then it also prevents the organic materials from turning into an amorphous poisonous blob that you would not want to get your hands at.
Familiarize yourself with the machinery (for industrial scale compost heaps)
If you are dealing with composting on a larger scale and it may require some machineries, you must really exercise caution in using the machinery. Also, make sure that you are familiar with all commands, well-versed with worst-case scenarios and troubleshooting techniques for the equipment you are using.
This is more dangerous, since you are talking of a composting heap on a larger scale. So make sure that you are familiarized, as well as the people around you who will be assigned to work with you on the industrial composting process.
