The new WHS legislation has added to the confusion surrounding testing and tagging - one of the key elements of electrical safety. In this article, Sarah Allen of Appliance Tagging Services explains the revised testing and tagging requirements across Australia.
Electrical fire hazards exist in almost every workplace and unfortunately, fires resulting from electrical hazards can lead to injury, fatality and damage to property. Common causes of electrical fires are overloaded equipment, electrical short circuiting of worn or damaged cables or heat generated by electrical equipment.
Since July 2011, New South Wales has witnessed a total of 55 incidents where cranes, machinery and other mobile plant have come into contact with power lines. This has prompted WorkCover to issue an alert reminding businesses, industry and workers of the dangers arising when operating mobile plant near energised overhead power lines.
The SIL 3 Safety Relay is created specifically for use in the emergency shutdown of plants and plant components in the process industry. The device meets the requirements of EN61508 as well as the safety demands of Safety Integrity Level 3.
Quint DC/DC converter power supplies equipped with selective fuse breaking can be used in hazardous zones and in shipbuilding. The converters trip circuit breakers reliably. Faulty circuits are selectively shut down so that the fault is localised and important system components remain operational.
The Times Protect LP-BTR high performance surge arrestor series addresses applications in the 200-1000 MHz spectrum. The DC blocking technology employed in this design provides optimum isolation of the antenna port from the protected equipment port for maximum surge protection.
The non-sparking and non-magnetic insulated tools and tool kits from Salisbury include wrenches, pliers, cutters, screwdrivers, sockets and tool kits, which can be used within environments where hazardous, flammable or combustible vapours, liquids, dusts or residues may be present.
Narda Safety Test Solutions has equipped its Selective Radiation Meter SRM-3006 frequency selective field measuring instrument with an LTE option (which can be retrofitted to older instruments).
Opening electrical cabinets to perform IR and visual inspections of live components is dangerous work, exposing technicians to the risk of a hazardous arc flash incident. Placing FLIR IR Windows between the user and their energised equipment adds safety and eliminates the need for opening enclosures.
igumid ESD has been designed for applications where there are any electrostatic discharges that are potentially damaging, for instance manufacturing or handling of sensitive electronic products and component parts.
Fluke Corporation has introduced the Fluke 28 II Ex DMM, a digital multimeter for measurements both inside and outside of hazardous zones. The device meets intrinsic safety (IS) standards worldwide (Qld pending) for safe use inside potentially explosive environments, making it suitable for use in petroleum, chemical and pharmaceutical facilities.
Electrical connectivity supplier Weidmuller has released its SIL 3 Safety Relay. Created specifically for use in the emergency shutdown of plants and plant components in the process industry, the device increases plant availability and safety.
WorkCover NSW has issued a safety alert to remind electrical workers of the inherent dangers of cutting electrical conduits that are in service. These conduits may contain multiple circuits. This is in response to an incident where an electrical contractor received a fatal electric shock. The contractor was replacing a faulty lighting circuit that was located in an underground heavy-duty PVC conduit. He isolated the lighting circuit at the meter board and proceeded to carry out the repairs.
