EXPLOSION-PROTECTED CAMERAS
THOROUGH EXAMINATION NOT ENOUGH TO ENSURE SAFETY IN HAZARDOUS APPLICATIONS
Pyroban is reminding explosion protected forklift users of the need to conduct Ex- annual safety audits (Ex-ASAs) alongside a Thorough Examination to ensure legal compliance and reduce risk in potentially explosive atmospheres. “To improve safety when using forklift trucks a
Three new explosion-protected temperature alarm and thermal network cameras allow plant operators to monitor remote, inaccessible and sensitive areas, allowing for rapid incident response and protection of employees, machinery and critical industrial infrastructure. Based on industry standards and open protocols and protected with a heavy-duty enclosure, the cameras seamlessly integrate with SCADA architectures complemented by thermal imaging. “Industrial plant operators have a
tremendously difficult task,” explains Martina Lundh, global product manager for thermal and explosion-protected cameras. “They need to ensure efficiency and continuity in large-scale, critical industrial processes while meeting all health, safety and environmental regulations across multiple locations and often across huge areas. Our new cameras deliver critical real-time information, allowing for immediate incident response which can prove to be a life-saving benefit.” Typical industrial applications for the
fixed XF40-Q2901/XF60-Q2901 Explosion-Protected Temperature Alarm Cameras include control and detection of temperatures of equipment and leaks in pipes, fire detection and monitoring of equipment and perimeter protection. They help visually inspecting and verifying functions and processes are running correctly and provide remote assistance with planned maintenance. Typical applications for the pan/tilt XP40-Q1942 Explosion- Protected PT Thermal Network Camera include detection of people in restricted areas and safety of personnel in hazardous areas. In addition, XP40- Q1942 supports Electronic Image Stabilisation and Zipstream technologies by Axis. The first greatly improves video quality in situations where a camera is subject to vibrations, providing smooth and comfortable live viewing. The second lowers the bandwidth and storage requirements while maintaining outstanding thermal imaging quality. Axis’ explosion-protected thermal
cameras and temperature alarm cameras are compliant with specific country regulations across the globe.

regular Thorough Examination is mandatory in many countries,” says group after sales manager Darren Boiling. “However, this alone is not enough to ensure safe operation in applications where there is a risk of explosion. If a truck has been converted for use in a potentially explosive atmosphere it is essential that the explosion protection system is inspected annually, or sooner, alongside a Thorough Examination of the truck itself.”
A Thorough Examination, usually organised by the
supplier of the forklift as part of a service agreement, is used to confirm that the truck can be operated safely and as it is intended to by the manufacturer. The inspection identifies any defects which could compromise the safety of the truck, checks on the
status of any previously identified problems and sets time-scales against which any new issues need to be addressed. Although Thorough Examination includes a review of the correct function of safety devices, this inspection does not assess the condition and function of explosion protections systems to the degree required for safe operation in potentially explosive atmospheres. Equipment is converted to EN60079-17 which states that an inspection routine should be introduced to ensure the continued safe operation of equipment. “When you are dealing with potentially explosive
materials the smallest spark or increase in temperature could become an ignition source so it’s imperative that equipment is inspected carefully and then maintained to the highest order during its working lifetime,” explains Boiling. Pyroban’s Ex-ASA inspects and records all safety critical components of the complete explosion protection system. The inspection which can be carried out at any location by one of Pyroban’s specialist auditors, checks for any irregularities. If none are found the truck can be declared safe for use and a certificate will be issued to support the Explosion Protection Document (EPD). Similar to a Thorough Examination, if any irregularities are identified, repairs can be scheduled and carried out by a Pyroban trained engineer and then re-inspected. “Comprehensive safety audits help businesses
comply with ATEX* 1999/92/EC by demonstrating that equipment has been maintained with ‘due regard for safety’,” concludes Boiling.

E2S Warning Signals has developed a comprehensive range of LED beacons for use as warning beacons and status indicators for systems installed in hazardous areas and industrial environments. The LED units, using a multiple array of high power white Cree LEDs, offer significant advantages over traditional Xenon strobe technology in many applications. The typical light output level from the LED units
is a very bright 338 candela, significantly higher than the 120 candela effective intensity of a 5J Xenon tube unit. E2S LED beacons have five flash rates for warning beacon uses: 1, 1.5 and 2 Hz and double and triple flashes. They have high and low power steady modes for status indicator uses, enhancing the typical life of more than 60,000 hours. DC voltage versions feature three remotely selectable stages enabling multiple warnings to be signalled from one device. The same light engines and control electronics
are at the heart of beacons available in all the product families in the E2S range. The STEx (316L stainless steel), GNEx and E2x (GRP) and BEx and D2x (marine grade LM6 aluminium enclosures) are all available with the new generation of LEDs providing a variety of mechanical protection, corrosion resistance, weight and price to suit different environmental requirements and applications. The polycarbonate, UV stable lenses are available as spare items in amber, blue, clear, green, magenta, red and yellow. While enhancing the light output, the lens filters are also field replaceable enabling the reassignment of beacon function to be a simple and quick process.
