STRESS ENGINEERING SERVICES (SES) IS A MULTI-DISCIPLINE ENGINEERING COMPANY THAT SERVES
A VARIETY OF INDUSTRIES. ONE OF THE SERVICES PROVIDED BY SES IS A TEST FACILITY IN WHICH A
VARIETY OF PRODUCTS ARE TESTED.
A SERIES OF TESTS WERE PERFORMED FOR SAFETY MAKER ON THEIR SAFETY BOOT
. THE PURPOSE
®
OF THE TESTS WERE TO DETERMINE THE MAXIMUM LOAD THE BOOT AND FLOOR ASSEMBLY COULD
WITHSTAND. THE TESTS WERE PERFORMED ACCORDING TO OSHA 1926.502 WHICH IS A CONSTRUC-
TION REGULATORY GUIDE FOR FALL PROTECTION GUARDRAIL SYSTEMS. THIS GUIDE REQUIRES THAT
THE GUARDRAIL SYSTEM MUST BE ABLE TO WITHSTAND A FORCE OF 200 POUNDS AT A HEIGHT OF 42"
ABOVE THE FLOOR.
A NUMBER OF TESTS WERE PERFORMED USING A VARIETY OF BOLTS AND SUBFLOORS. BELOW IS
A TABLE AND PLOT THAT SUMMARIZES SOME OF THE TEST RESULTS. IN ALL TESTS SHOWN, THE
SAFETY BOOT ASSEMBLY EXCEEDED THE OSHA REQUIREMENT OF 200 POUNDS FORCE. THE TESTS
HAVE SHOWN THAT IT IS IMPORTANT TO HAVE THE CORRECT COMBINATION OF LAG BOLT SIZE, WASHER
SIZE, NUMBER OF LAG BOLTS AND FLOOR MATERIAL THAT THE SAFETY BOOT IS ATTACHED TO. SOME
FLOOR MATERIALS, SUCH AS PLYWOOD LESS THAN 1-1/8" THICK AND OSB, ARE INSUFFICIENT BY
THEMSELVES AND MUST HAVE ADDITIONAL SUPPORT (2" PINE BOARD) FOR THE BOLTS TO PENETRATE.
WITH THE ATTACHMENT COMBINATIONS SUMMARIZED, THE SAFETY BOOT EASILY EXCEEDED THE OSHA
MINIMUM REQUIREMENT OF 200 POUNDS FORCE.
