Every year, millions of workers suffer non-fatal workplace injuries — 6 million to be exact. This results in an annual cost of $125 billion for U.S. businesses, a good chunk of which goes to employee hospital stays.

To save on costs and improve workplace safety, it’s important to first understand which job hazards are leading to hospitalizations. Here are some common sources.

A job hazard analysis, often referred to as a job safety analysis or task hazard analysis, is an excellent way to systematically reduce the dangers within your worksites. OSHA also recommends them for the reduction of workplace injuries and illnesses, and well-documented JHAs could help you out during an audit.

JHAs are particularly useful for rooting out and mitigating the causes of falls — an all-too-common source of on-the-job injuries. One of OSHA’s “Fatal Four,” falls accounted for 364 out of 937 total deaths in the U.S. construction industry in 2015. Following are a few steps for using JHAs to mitigate fall hazards in your organization.
