WORK AT WORKING SAFELY Training is the key to success in managing safety in the work environment. Attitude is also a key factor in maintaining a safe workplace. Safety is, and always will be a team effort, safety starts with each individual employee and concludes with everyone leaving at the end of the day to rejoin their families.
