Today we will cover: Fatalities associated with tires, 1980-2000 Tire Injuries, 1996-2000 Tire Safety Tips Prioritization of safety programs based on passive data Background NIOSH Spokane Research Lab Project: Surface Powered Haulage Safety  Project Objectives: Detection of Vehicles or Personnel in Blind Spots Monitoring of Driver Awareness Health and Safety Hazards to Personnel Responsible for Powered Haulage Equipment Maintenance and Operation Hazards to Maintenance Workers: Frequent heavy lifting High pressure hoses and vessels Work in awkward or confining spaces Exposure to potentially hazardous substances (oil, gas, engine fluids, welding fumes, etc.) Proximity to moving parts, hand tools, and machinery. TIRE FATALITIES From 1980-2001.2 What can we learn from 20+ years of data? But first, a little note on data analysis... About the fatality data... All data was obtained from the Mine Safety and Health Administration’s (MSHA) on-line files of raw data from the accident and injury 7000-2 forms filed by mining operators and contractors as required under 30 CFR Part 50 from 1980 through the 2nd quarter of 2001. (n = 575,853 reported cases) Since accidents and injuries related to tires occur across a broad range of accident categories, records with narratives containing keywords “tire,” “rim,” “lug,” and “wheel” were extracted. It is assumed that no tire-related accidents occurred without one of these keywords in the narrative. (data subset n = 11,442 records) A little more about the fatality data... The data subsets were further separated into fatal vs. non-fatal accidents (n = 88 fatality records containing one or more keywords) Each narrative was read and assigned to a self-defined accident category*. Records not related to tire safety (n = 57) were discarded. From this data, it was determined that 31 tire-related fatalities occurred between 1980 and 2001.2 Frequency of Tire-Related Fatalities(1980-2001.2) What Caused the Tir
