Machine Guarding: Pinch Points & In-Running Nip Hazards - Expert Webinar [VIDEO]
Pinch point and in-running nip hazards are associated with some of the most gruesome machine accidents we have investigated. Absent proper guarding, these design features have the potential to entrap a worker and pull them further into the machinery.
In this webinar video, Mechanical Engineer Jack Green, P.E. provides an overview of machine guarding by focusing more narrowly on pinch points and in-running nip hazards. His discussion includes an overview of the design safety hierarchy, common machine arrangements that result in these hazards, and some of the approaches taken by design engineers to prevent injury. Information will be conveyed through prior case examples in a way that will be applicable to a broader range of industrial mishaps.

Failures & Fundamentals: Hydraulic Systems - Expert Overview
In this article, machinery experts at Robson Forensic provide an introduction to hydraulic systems and the hazards they present. Hydraulic systems are used everywhere, from forklifts to landing gear to industrial systems and the largest earth-moving machinery. Some of the most complex and critical life safety hydraulic systems are found on board ships and aircraft. Expertise in those environments translates well to industrial applications on terra firma. Required to be powerful and reliable, hydraulic systems are not, however, immune to malfunction and failure.
