On-the-job training can prevent a variety of injuries, from mild to severe, but without it, construction workers may be making decisions or taking actions without proper precautions or preparation. All workers should be provided with thorough training on the tools they will be using, the work they will be doing, and the potential hazards that they may face. Every job site should include information about safety procedures, and the names and contact information for trained EMTs or first aid providers. Equipment should be reviewed, and use should be restricted to those who have received the proper training.
