WORLD-CLASS SAFETY PERFORMANCE

Rico Elder, a 22-year Martin Marietta
employee, practices a steady hand as
a yard loader operator.
Martin Marietta’s heritage operations* maintained their focus on safety in 2018, resulting in a reduced total injury
incident rate (TIIR) and lost-time incident rate (LTIR) compared with 2017, which was itself a record year. This is the
_
third straight year both metrics have improved for our heritage operations. Our comprehensive safety figures inclusive
_
of recently acquired operations are equally impressive, including world-class LTIR for the second year in a row. Details
of our companywide safety performance are reported below.
