Safety Blocks

Occupational Safety and Health Administration (OSHA) standard 1910.217 for mechanical power presses requires use of safety blocks.

"The employer shall provide and enforce the use of safety blocks for use whenever dies are being adjusted or repaired in the press."

Please refer to 1910.217(d)(9)(iv) as referenced in OSHA document:
Regulations: Machinery and Machine Guarding / Standard Number: 1910.217.
Information is also available online from the
American National Standards Institute B11.1-2009 document
Refer to section 9.2.6 "die adjustment, cleaning, or repair."

Safety blocks are designed to prevent accidental die closure during press setup and maintenance. Safety blocks are constructed from lightweight extruded aluminum or magnesium and are available in fixed lengths with wedges for minor adjustment or adjustable versions. Consideration should be given to the weight of safety blocks as they can sometimes be cumbersome to lift where press bolster heights are well off the floor.

Static load and open height requirements determine the optimal size and style of safety block. See the download sheet for more details or contact our Application Engineers for more information.
