The need to evaluate hazards and apply corrective actions to reduce those hazards began years ago. Over the past 12-plus years this process has been refined, documented in standards and regulations, and it’s now a requirement. A general term defined for this process is “risk assessment.” Below, learn who a risk assessment is for and some best practices for...
Can a U.S. original equipment manufacturer (OEM) ship a machine without safety integrated into or included as part of the machine? Aren’t there regulations requiring machine manufacturers to provide machine guarding? An example of basic machine safety is an emergency stopping device, such as an e-stop.
When deciding to apply a device to achieve a safety function, by default, that safety function should be achieved each time, actuated consistently and within a certain time period. For machine hazard mitigation, review these four points when considering risks and reliability of controllers versus safety controllers, defined by IEC 61508 (Functional safety...
Machine safety validation is defined by the international standard ISO 13849-2, Part 2: Validation, which specifies the procedures and conditions for analysis and testing of the specified safety functions, the category achieved, and the performance level achieved. Some functional safety reliability results from a machines’ software design. See 5 steps often...
Upon reviewing a machine that has two interlock switches mounted to an access door, can you say that the machine is safe? Most industry experts today would say, "Probably not." Here's an explanation of why and the relevant standards.
Look at the 5 levels of hazard mitigation to help determine risk of a machine no longer in use. Consider the following 12 hazards of end-of-lifecyle machines. An unused machine is not necessarily safe.
Some recent reports, cyber attacks have grown by 600% since 2010 costing industry around $400 billion a year impacting productivity, machine uptime and profitability. Machine safety automation also addresses productivity, uptime and profitability. Perhaps “safety” and “security” efforts should combine.
Yellow line theory versus complacency: On a train platform few people cross the yellow line, without any specialized training, yet, in a manufacturing environment, accidents happen regularly after people cross the yellow line and even more formidable barriers. Why?
International Labor Organization said every 15 seconds approximately 160 workers have a work-related accident, and one of those injured workers will die. So, does it make sense to keep detailed records of injuries to claim that an absence of injuries equates to the presence of safety? Know the 5 progressive steps to a strong safety culture.
