Electrical Equipment Guarding and Workspaces Electrical current is found in power lines, transformers, breaker boxes, and power outlets and switches. Exposure to electric current can cause shock, injury and electrocution. Workers that service electrical sources need to get training on electrical safety, assume electrical equipment and lines are live, and use lock-out/tag-out procedures. Proper guarding and clearance around electrical equipment can prevent accidental worker exposure to electrical currents. A shock can occur when a worker’s body becomes part of the flow of an electrical circuit. The severity of injury depends on the voltage and time that the electrical current passes through the...

Cumulative Trauma Disorders (CTD's) are strains that may result from long-term repetitive motion or from continually working in an awkward position. Strains commonly occur in the wrists, arms, shoulders or back, affecting the body's joints and surrounding muscles and tendons. CTD's are said to be today's fastest growing occupational problem, affecting all types of employees, from computer operators to construction workers. Modern equipment, tools and machinery have increased production capabilities in many ways. But in some cases, they have also increased the potential for strain injuries in people. These disorders not only cause great discomfort, they can also affect a person's...

Chemical Hazards - Composite Safety Chemical Hazards - The materials most commonly used in composite manufacture are: resins, catalysts, and strengthening materials (fiberglass, Kevlar, Scorefoam). Polyester, vinylester, and epoxy are the most commonly used resins today with the catalysts being either Methyl Ethyl Ketone Peroxide (MEKP), Benzoyl Peroxide, or an epoxy Part B catalyst (depending on the system used). Fiberglass, carbon fiber, Kevlar and Scorefoam are the most commonly used strengthening materials. Depending on the use of the material, they all produce various hazards. The hazards commonly experienced with these types of materials are: overexposure to vapors, inhalation of particulate fiber, industrial...

Cold Weather Driving Living and working in cold areas means having to navigate cold weather driving. In Wyoming, the weather can change very quickly. Many accidents could be avoided if you take the time to learn and practice these tips for driving safely during snowy and icy conditions: Perhaps the deadliest danger of all is "black ice." Black ice forms on a roadway, usually due to snow melting and re-freezing. Since it is almost invisible, drivers fail to recognize black ice conditions and may drive at normal speeds-often resulting in very serious accidents. Always be alert to the possibility of black ice when...

Cold Medication & Drowsiness Cold and flu season is here again. Now is a good time for our annual warning about using over-the-counter cold and flu medications during work hours. Sometimes, cold remedies and work are not a good mix. The most common side effect of over-the-counter cold and flu medicine is drowsiness, which lowers one's alertness and reaction time. Ten to twenty-five percent of people taking these medications report daytime drowsiness. This can be more than just an annoyance. Approximately 200,000 vehicle accidents are attributed to sleepiness every year. Fatigue is a factor in nearly one-third of truck accidents where the...

Chemical Hazards Hazardous Materials Identification System Under the Hazard Communication Standard put forth by OSHA, virtually all hazardous chemicals used in the workplace are required to have labels that indicate the type and level of the potential hazard. The warning labels used to identify chemical hazards have a universal color and numbering system. They also utilize a letter designating what type of personal protective equipment is needed. This makes it easier for you to tell what type and level of hazard you are dealing with. Colors are used to show the specific kind of hazard, and numbers within the colors are used...

Dermatitis Dermatitis is an inflammation of the skin from exposure to an irritant. The degree of inflammation is affected by the type of skin (pigmentation, dryness, hairiness), age, sex, season of the year, history of previous skin disease or allergies, and personal hygiene. Although one exposure to a substance may be enough to cause a skin reaction, workers can become sensitized through prolonged and repeated exposures to a substance. The delay can be as short as a day, but can be as long as several months. Generally, causes of dermatitis are chemical, mechanical, physical, or biological. Chemicals can produce reactions ranging from chemical...

Bloodborne Pathogens (BBP) Bloodborne Pathogens - Safety At All Levels Individuals who are infected with a bloodborne pathogen may not know they are infectious. Hepatitis B Virus (HBV) or Human Immunodeficiency Virus (HIV) may not show symptoms. For this reason, all human blood and body fluids should be considered as if infectious, and all precautions should be taken to avoid contact. This simple rule is known as "universal precautions." In the workplace, bloodborne pathogens (BBP) may be transmitted when blood or other infectious body fluids come in contact with mucous membranes (your eyes, nose, mouth); non-intact skin (due to cuts, abrasions, burns, rashes,...

Avoiding Electrical Shock Electrical shock hazards can be found in all industries. Avoiding electrical shocks both at home and at work requires awareness of the hazards and respect for this "Silent Killer." The human body has a low resistance to electricity, making it a good conductor, like most metals. Unlike metals, however, the human body does not respond well when electricity passes through it. Physical results include thermal burns, disruption of normal heart activity, severe muscle contractions, and even death. The most common and serious electrical injuries occur when electrical current flows between the hands and feet. This happens when a person...

Assured Equipment Grounding and Ground Fault Circuit Interrupters (GFCI) Electric shock, and too often fatalities, occur on construction jobsites when temporary power systems are in use. All construction workers who operate power tools should receive training in the systems that safeguard them from electrical hazards. What is the difference between an "Assured Equipment Grounding Program" and GFCI? An Assured Equipment Grounding Program is a scheduled system for testing construction site electrical tools and extension cords to assure their proper grounding, polarity and resistance. A Ground Fault Circuit Interrupter (GFCI) is equipment that serves as a circuit breaker if continuous ground continuity...
