The most useful feature is the ability to create a customized safety program for each job site. The ability to create an online training program is great. The ability to create training materials for each job site is also great. 1Life does not have the ability to create a customized safety program for each job site. You must create one safety program for all job sites. The safety program must be reviewed and approved by the client. 1Life does not have a way to track changes or updates to the safety program. 1Life is a great tool for creating an online training program for all job sites. The ability to create training materials for each job site is great. I like that this program is easy to use and very customizable. There are some helpful tutorials available so it's not too difficult once you get used to how things work. Sometimes there can be some technical difficulties when updating the software but those seem to be minor issues. This program helps keep track of safety data as well as other important information for my business. It also provides me with a way to communicate with my employees about their health and safety at work.
