StaCool Industries has launched the StaCool vest core body cooling system (Figure 2), which keeps users cool, comfortable, and productive while working in the summer heat, without compromising mobility. Maintaining a consistent core body temperature is safer than exposing workers to possible heat-related illnesses, and because wearers do not require cooling breaks, they are considerably more productive. Each vest is made from breathable Airprene material for comfort and flexibility, and includes ThermoPak inserts that comfortably cool the body core. The lightweight cooling vest provides up to three hours of cooling per ThermoPak set (four per set), depending on activity type, environmental conditions, and body heat. Each StaCool vest includes an additional four ThermoPaks, so users have a spare set to extend cooling time. StaCool vests are ideal for welders and other industrial/manufacturing workers.

A large number of utility workers have been maintaining a home office during the COVID-19 pandemic, while others have been sheltering at power plants as workhour regulations have changed due to the coronavirus. Force 5, a utility security provider, has taken a unique approach to keeping staff healthy during the pandemic. Force 5 has issued kiosks with view monitors (Figue 3) to their users’ workstations, asking workers health-screening questions before entering critical areas or even interacting with critical personnel. James Evelyn, vice president of Compliance Solutions for Force 5, said of the company’s equipment: “These cameras use infrared thermal imaging and will integrate with Force 5’s kiosks to automate virus screenings and to prevent entrance for anyone whose body temperature is elevated and outside of the specified temperature range.” Force 5’s integration laser thermometer checks staff’s temperature through a digital infrared/non-contact thermometer that integrates with their kiosk to automatically reject someone entering the facility if the provider sets it up in that way. This software was implemented to make sure critical infrastructures inside and outside are protected. Force 5 Solutions, Miami, Florida

Dropsafe recently announced it is expanding its barrier range (Figure 7) to meet industry demand for robust drops prevention solutions across all environments, including for power generators. As new facilities come into operation in different regions, there has been growing recognition that the risks of drops must be tackled, but also that drops prevention solutions that suit an operation in one region may not be suitable in another. The Dropsafe Barrier XE (extreme environment) is rated for harsh offshore conditions, very high levels of ultraviolet (UV) radiation exposure, and extremely cold weather. The Barrier XE is ideally suited to operations in northern latitudes such as Russia, Alaska, or Canada. The Dropsafe Barrier ME (moderate environment) is able to withstand the same impacts and wind loading as the XE. It is tailored for temperate offshore and onshore environments where high levels of UV and temperatures below –5C are not a factor. This includes power stations, refineries, mines, and offshore rigs outside of extreme cold regions. The two barrier variants both provide superior standards of drops prevention, with extra flexibility to withstand Cat 3 or Cat 5 wind speeds depending on the option chosen during the installation process.

Dinkle International recently announced the availability of its DPT DIN rail disconnect terminal blocks (Figure 8) to provide efficient, safe disconnect and testing of current transformer (CT) and voltage transformer (VT) circuits. CTs and VTs isolate a primary power feed from a secondary circuit, permit grounding of the secondary circuit, and step down the current or voltage to an appropriate level for measurement. Terminal blocks are then used as the termination points for instrument loops on the secondary circuit. Panel builders have traditionally incorporated barrier-type terminal blocks in CT circuits—but these are challenging to access, require proper tools, and take time for backplane mounting and screw-down wire terminations. Additionally, there is always the danger of under-torqueing and loose wiring connections, or over-torqueing and stripped screw threads. Dinkle’s DPT DIN rail series terminal blocks address these issues by providing easier access, DIN rail mounting with no tools required, and push-in design to ensure secure wiring connection while reducing time and tools required for termination. The DPTD6 model block also provides direct-testing technology, enabling a user to test the circuit current without undoing any wired connections. Dinkle International, Taipei, Taiwan
