does not interfere with its operation or with people working on or in the vicinity of the plant. Lasers Lasers are devices that produce optical radiation with unique properties. They have varying power and applications. High power laser devices can present a hazard over considerable distances from the source. While exposure to some higher powered laser products may cause skin burns, most laser injuries are to the eyes. For example, some laser pointers available on the market are of sufficient power to cause eye injury. Laser products may consist of a single laser with or without its own power supply or multiple lasers in a complex system. SAFE WORK AUSTRALIA MEMBERS’ MEETING 6 30 SEPTEMBER 2010 PAGE 42 OF 52

R. 223: Lasers must be designed and installed to prevent accidental irradiation of any person. The laser equipment must be protected so that any operator or other person is not exposed to direct radiation, radiation produced by reflection or diffusion or secondary radiation. Visual equipment used for the observation or adjustment of laser equipment on plant must not create a risk to health or safety from laser rays. All laser devices must be sold with appropriate information about their safe use. This generally takes the form of a label with both the classification details and the warnings-for-use that are appropriate to that classification. The warning labels appropriate to the class should be permanently affixed to the housing in a highly visible position. Designers should consult with manufacturers, suppliers, owners and end users to ensure that the correct strength of laser is used and the housing of the laser unit is designed according to safe design principles. The designer should ensure that complete written information on the safe use of laser products is provided to manufacturers, erectors, installers, suppliers, owners and end users. Laser devices sold in Australia should be classified in accordance with AS/NZS 2211.1:1997 Laser safety - Equipment classification, requirements and user's guide. Radio frequency radiation Radio frequency radiation (RFR) is electromagnetic energy (wave) that is transmitted at frequencies between 3 kHz and 300 GHz. Radio frequency (RF) generating plant may be used at workplaces that perform forging, annealing, tempering, brazing or soldering, sealing of plastics, glue drying, curing particle boards and panels, heating fabrics and paper, or cooking by means of a microwave oven. Workers in industrial workplaces that use RF generating plant are at risk of exposure to levels of RF fields where radiation may cause adverse health effects. For example, RF fields greater than 10 MHz interact with human tissue to raise the temperature and cause heat stress related illness such as impaired concentration, numbness, and eye damage. Usually those workers operating the plant are the most likely to be exposed. However, workers who do not operate RF generating plant but are situated within its vicinity and people coming into the workplace can also be at risk from the generated radiation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
