Office Ergonomics-Contact Stress: This Is What Professionals Do

Image
  Contact Stress- Contact stress results from occasional repeated or continuous contact between sensitive body tissue and a hard or sharp object contact stress commonly affects the soft tissue on the fingers, palms, forearms, thighs, calves and feet. Prolonged contact stress can inhibit blood flow, tendon and muscle movement and nerve function. One common example is resting wrists or elbows on the sharp edge of a desk or workstation, while performing tasks this can take place, while typing with the keyboard either too close or too far away using the mouse for a prolonged period of time can also lead to contact stress. The stress can be prevented by repositioning commonly used workstation items floating hands above the keyboard and reducing tension in the shoulders eliminates potential contact stress using a keyboard tray eliminates contact with a work surface edge and keeps your arms in a neutral position. Optimal neutral arm position has the arms relaxed at the side of the body with a

Hand Injury

Image
We use our hands constantly, a disabling hand injury can have a dramatic effect on your quality of life, a hand injury can impact job and daily routines as well a hand injury can occur  during a  second, but the social financial and emotional effects can last a lifetime. The  physical body  is an engineering marvel, our hands  contains  27 bones, ligaments, muscles, tendons, nerves, blood vessels, skin, and nails. Working in unison  they supply  strength and dexterity which enables us to perform routine tasks  and attain  precision movements. However,  due to  their tremendous versatility, hands are exposed insusceptible  to several  sorts of  injuries these include strains and sprains from excessive force or excessive repetitive motion, skin irritation from contact and exposure to hazardous or irritating substances, burns from electricity, chemicals and hot substances, punctures from sharp objects, lacerations, cuts,  starting from  minor to major fractures broken bones from

Eye Protection | Health and Safety

Image
According to the OSHA, enough people in the world suffer eye injuries at work, each and every month of the year to fill this entire arena past its seating capacity. And if that's a depressing statistic, here's a related one. Ninety percent of those injuries would have been prevented just by the use of proper eyewear. There are dozens of things in every workplace that pose hazards to our eyes, those most fragile exposed parts of our bodies. Sparks, chemicals, flying particles, and a significant number of trips to the emergency room, every year are caused by splinters in the eye. The effect of those hazards can be demonstrated by a common tool and one that’s a common source of injuries: the stapler. An injury like that would probably have been prevented just by wearing ordinary glasses. However ordinary eyeglasses aren’t really an effective form of eye protection as this person discovered while operating a powered lawn edger. Nail guns, for example, are causing more and

Hydrostatic Pressure Testing | Health and Safety

Image
Saudi Aramco Oil Company is one of the biggest oil companies in the world with a 21000+ km long pipeline network having reliable customers around the globe. Safety is the highest priority, so routinely conduct tests designed to measure that pipeline segments are sound, often referred to as pipeline integrity. One of the common methods for checking pipeline integrity is the Hydrostatic Pressure Test. Hydrostatic Pressure Testing is a process that uses water to exert pressure on a pipeline at levels greater than its usual operating pressure to see if it has any leaks. A segment of pipeline designated for testing is temporarily removed from service by closing the nearest valves on both ends to stop the flow of natural gas. To expose and access the pipeline, excavations are dug at both ends of the test segment and the gas remaining inside is safely vented. The short sections of the pipeline are removed to isolate the test segment. Then the open ends on both sides of the te

Safety of Pressure Vessels and Pressure System

Image
  Pressure Vessels A pressure vessel consists mainly of a series of sheets of metal suitably shaped and welded together. They are designed to contain stored energy above atmospheric pressure. Pressure vessels, typically steam boilers and air receivers, are inherently potentially dangerous items of plant and there is a long and tragic history of accidents associated with them. -Typically injuries relate from: The impact from the blast of an explosion or release of compressed liquid or gas. Impact form parts of equipment that fail or any flying debris. Contact with the released liquid or gas, such as steam, and fire resulting from the escape of flammable liquids or gases; and Oxygen depletion or enrichment. -The typical causes of pressure system failure are: Poor equipment and or system design. Poor maintenance of equipment. An unsafe system of work. Operator error, poor training, and supervision. Poor installation: and Inadequate repairs or modification. St
