Safety Circuits, Force Guided Relays vs. General Purpose Relays

Life without standards would result in near chaos for both manufactures and consumers. Just think if you could not rely on the strength of a critical fastener in an aircraft fuselage, the quality of the glass in a high rise building, the voltage fluctuation of the electrical grid at a faraway vacation destination, a crucial replacement for an electrical motor, the purity of a critical medication or the mere annoyance of not finding a correct battery for that digital camera. In short, as consumers, we would soon notice the lack of standards when the safety, quality, fit, reliability and compatibility of the products we consume, purchase and rely on are compromised.

June 2024 marks National Safety Month, an annual occasion to highlight the critical importance of workplace safety and raise awareness about potential hazards. For industries that rely on industrial equipment and heavy machinery, proper maintenance practices and safety protocols are vital for preventing accidents, injuries, and fatalities. Continuously striving to improve workplace safety is not only the ethical thing to do, but also keeps facilities productive, reduces downtime, and protects businesses from legal action.

High-pressure injection injuries, also known as grease gun injuries, are caused by the accidental injection of a foreign material–such as grease, oil, or solvent under pressure–through the skin and into the underlying tissue. This is analogous to medical techniques used to administer immunization shots without a needle. A grease gun injury can cause serious delayed soft tissue damage and should be treated as a surgical emergency. Any person sustaining an injury of this sort should seek immediate medical attention, regardless of the appearance of the wound or its size. Accidents involving injection injuries can occur when using any type of pressurized equipment.

Every year, tens of thousands of maintenance workers get injured on the job or develop work-related illnesses. While not all of these incidents can be avoided, many can be with the proper personal protective equipment (PPE for short).

Trelleborg has developed a product, that can withstand a jet fire - the cause of the Piper Alpha disaster. The product is already in use on several platforms, primarily in the North Sea. To date, some NOK 7 million in development costs- has been invested annually. These costs are shared by the project sponsors, comprising the Norwegian government and a number of oil companies. Continued development is not expected to be as costly and will focus more on handling other derivatives, such as gas and oil, and possibly being able to offer a material in other colors for customers who wish to customize their equipment using their own color schemes.

With literally thousands of dangerous materials being used/transported/discarded every day, the process of choosing protective clothing has become increasingly complex for today's safety and hygiene professional. It is important to understand the distinction between three broad types of protective garments used today. Generally classified as disposable, reusable, and limited-use garments, these three general categories provide a basic framework for clothing decisions.

In the past few years, Hydrovacs and "daylighting" have gained industry acceptance by minimizing the challenges of exposing underground pipelines, fiber-optics, and utilities. "Daylighting" is a non-destructive process using pressurized water (hydro) and a vacuum system (vac) to remove soil cover, thereby allowing a visual observation of underground lines. Hydrovacs expose these facilities to daylight, thus the term "daylighting".
