  • Page 2 Employees should be aware of possible dangers in operating or working around lift equipment. This type of machine operates in and around rough terrain. This environment increases the potential hazard in operating these machines. This naturally requires alertness and caution by you to prevent accidents while achieving expected productivity from your machine.
