According to ANSI B11.19-1990, “the size of the safety mat should be large enough to prevent entry
into the hazardous area. In some cases, this may require the use of more than one mat or additional
safeguarding.” (Section E4.2.5.2.1)
The safety mat must be of sufficient size to detect entry by an operator or others into a hazardous
area. Universal safety mats are available in a variety of standard sizes, call STI for sizes and
availability. If you need to identify an existing Universal safety mat, you may look in the STI catalog
for instructions on how to determine the model number, or call STI for assistance. Knowing the
distance that must be covered with safety mats from the hazardous area of the machine is critical to
a safe installation.

The Universal safety mat is designed to be secured to the mounting surface with the perimeter trim.
The mat has an inactive (non-sensing) area 1/4 in. (6.25mm) wide around the perimeter of the mat
at the edge. This inactive edge fits under the perimeter trim such that, with the trim installed, the
exposed surface of the mat is active.
Two or more mats placed adjacent to each other to form a large sensing area must use the Active
Joining Trim. The proper installation of the Active Joining Trim will create a fully active sensing
area in accordance with EN1760-1:1997.
