Having an Intrinsically Safe Workspace

(IS) is a protective technique for the safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. In normal use, electrical equipment often creates tiny electric arcs (internal sparks), this becomes an ignition source. For handheld electronics, intrinsically safe is the only method that allows a device to be explosion proof. These devices are incapable of producing sparks or heat which can cause the product to ignite and cause an explosion. This is done by limiting the voltage and electrical currents that enter any hazardous areas. For example, during the transfer of […]

Blue is the New Green

Historically mercury thermometers have been used for nearly all temperature measurements because of their accuracy and low cost. Their use is increasingly being restricted to industrial and scientific applications, as safety and environmental issues are demanding stricter laws on the disposal of products containing mercury. Thermometers are typically constructed of a hollow glass tube with a reservoir at one end to hold a liquid, which is sensitive to temperature fluctuations within a specific range. Mercury thermometers present many safety and environmental hazards. Mercury in thermometers, if introduced into the environment can eventually enter the water ecosystem, where microorganisms break it […]

OLE Tank Gauges – Our Clients’ First Choice

OLE Tank Gauges – Our Clients’ First Choice

Used to indicate the level of fuel in a tank, tank gauges need to operate accurately and efficiently every time. The best tank gauge for the job? OLE. Here are nine simple reasons why: Time-saving: Tank dipping can be a lengthy process, requiring a temperature measurement and correction mathematics. OLE tank gauges reduce the required number of physical dips, saving you precious time. Continuous indication: Because they use digital gauging, OLE gauges provide a continuous indication of tank contents. High accuracy: OLE gauges measure litres using hydrostatic pressure. This results in high accuracy, perfect for the ‘standard supply’ temperature (20ºC […]

When it comes to tank dipping equipment, Rigana has been tried and trusted since 1982.

At Rigana, bulk fuel management is one of our specialities. For while industries such as Petro-Chemical, Mining and Aviation cannot regulate the cost of fuel, they can use systems and products to manage how fuel is used and monitored within their operations. Bulk fuel management requires good control records, stringent safety regulations, the use of well-maintained equipment, and proper measuring tools. All these factors will help prevent the loss of fuel, through leaks, unauthorised use, or theft. When receiving and storing fuel, industry recommended practices include checking product levels, water levels, product temperature, and product density. Our range of specialised […]

Security Seals – What’s the Big Deal?

Security Seals – What’s the Big Deal?

When it comes to transporting goods, security seals can make all the difference. Designed to help detect theft or contamination (either accidental or deliberate), they are considered an inexpensive way of providing tamper evidence or evidence of intrusion into “sensitive spaces”. Depending on the material used and the design of the seal, they also provide some level of security. Applications include sealing of containers, valves, gates, doors, meters, trolleys, tankers, drums, keys, vehicles, cages, boxes, bags, sacks, hazardous waste, legal evidence, and fire extinguishers. A slightly different application is when seals are used for asset tagging. Spoilt for choice! Which […]
