Hospitals, behavioral health facilities and detention centers are at high-risk for sentinel suicide events, even when regular monitoring checks are in place. Statistics from 2010-2017 show that over 70 percent of suicide attempts during hospital inpatient treatment utilized a ligature or strangulation point and almost 54 percent of those used a door or door hardware1. To mitigate suicide risk more effectively facilities are making an effort to create spaces to keep patients safe from self harm.

Schlage offers a comprehensive portfolio of door hardware that reduces the risk of injury or death due to ligature strangulation in all areas, but the SK1 is recommended for low-medium risk applications.
