48 BUSINESS AND TRAINING Occupational hazards, stressors in the workplace The adage ‘Cowboys don’t cry’ is nonsense when it comes to stress. Occupational hazards can seem juxtaposed to workplace stressors, but there is a confluence of elements that can cause one to feel stressed about the possibility of sustaining an occupational injury. If you identify and curb these stressors early on, it is manageable, writes Rory Macnamara. The workplace can be perilous where safety is concerned. Stress factors must be treated with the same regard. • • NOISE The Occupational Safety and Health Administration reports that hearing loss from excessive noise is a predominant occupational concern. Much of this hearing loss is preventable through taking appropriate safety measures, such as wearing earplugs or reducing the loudness of the noise. Workplace accidents and injuries can also increase due to excessive noise, as workers may not hear warning signals or simply may not be able to think straight due to the constant disturbance within their environment. EYE INJURIES What contributes to eye injuries at work? • Not wearing eye protection Reports show that nearly three out of every five workers injured were not wearing eye protection at the time of the accident. • Wearing the wrong kind of eye protection for the job About 40% of the injured workers were wearing some form of eye protection when the accident occurred. These workers were most likely wearing eye protection with no side shields, though injuries among employees wearing full-cup or flat-fold side shields occurred, too. WHAT CAUSES EYE INJURIES? • Flying particles BLS found that almost 70% of the accidents studied resulted from flying or falling objects, or sparks striking the eye. Injured workers estimated that nearly three-fifths of the objects were smaller than a pinhead. Most of the particles were said to be traveling faster than a hand-thrown object when the accident occurred.

Other accidents Other accidents were caused by objects swinging from a fixed or attached position, like tree limbs, ropes, chains, or tools that were pulled into the eye while the worker was using them. EXTREME TEMPERATURES Heat stress is the overall heat load to which a worker may be exposed from the combined contributions of metabolic heat, environmental factors (such as air temperature, humidity, air movement, and radiant heat), and clothing requirements. Metabolic heat is the heat produced by the body through chemical processes, exercise, hormone activity, digestion, and so forth.

Cincinnati, Ohio: American Conference of Governmental Industrial Hygienists.] Heat may emit from many sources. For example: • In foundries, steel mills, bakeries, smelters, glass factories, and furnaces, extremely hot or molten material is the main source of heat. • In outdoor occupations, such as construction, road repair, open-pit mining, and agriculture, summer sunshine is the main source of heat. • In laundries, restaurant kitchens, and canneries, high humidity adds to the heat burden. In all instances, the cause of heat stress is a working environment that can potentially overwhelm the body’s ability to deal with heat. Most people feel comfortable when the air temperature is between 20°C and 27°C, and when the relative humidity ranges from 35% to 60%. When www.plumbingafrica.co.za
