Decreasing Slips, Trips, and FallsSlips, trips, and falls (STF) are the leading cause of construction fatalities and account for one-third of on-the-job injury deaths in the industry. In the U.S., more than 200 construction workers are killed and over 10,000 are seriously injured by falls each year.

In an effort to address STF injuries, M. J. Electric inaugurated a truck committee in 2017 to undertake STF possibilities with our mobile equipment. The committee, sponsored by John Holtz (Vice President, Central Region) and Bill Shaw (Vice President, Eastern Region), was established to mitigate and eliminate potential STF hazards from mobile equipment. A five-part solution was developed that included painting our equipment with high gloss paint, a hand rail system, bucket liner step, vehicle housekeeping, and awareness training.

High gloss, non-skid paint will be applied to key areas on the equipment to highlight visibility and increase foot traction. Step relocation and a collapsible hand rail system will be utilized to address access and egress themes. A new bucket liner with a pre-molded inner liner step will be employed to allow greater mobility when exiting the bucket. Vehicle housekeeping and awareness training will be incorporated to maintain cognizance to the STF safeguards.
