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...

Hot Work Procedures Hot work may include spark and high heat-producing job tasks such as grinding, welding, soldering, thermal or oxygen cutting or heating. Advanced planning and safe work procedures help prevent workplace fires caused by hot work activities. Get training on hot works tools and processes. Know how to assess the fire risk, prevent fire, extinguish a fire, and activate an emergency response. If you are a designated fire watch, get annual training on these procedures. Wear the appropriate personal protective equipment for hot work, including tinted eye protection and a face shield. Wear fire-retardant clothing and a welding vest and...

Chocks And Blocks An essential part of a safe working environment when loading or unloading trucks and trailers is the proper use of equipment, which includes chocks and blocks. Every year, workers are severely or fatally injured because the wheels of a truck or trailer were not chocked. Vehicle drivers are also injured when trailers overturn because unblocked freight shifted during travel. When wheels aren't meant to roll. Accidents are caused each year when a truck or trailer rolls away from the dock because no one took time to chock the wheels. In some cases, drivers who got out of the cab...

Be Cautious With Sulfuric Acid Sulfuric acid is widely used in industry for a variety of purposes such as metal cleaning and etching, the production of fertilizers, petroleum products, dyes and explosives. Like all acids it is reactive. Simply put, this means that when the liquid comes into contact with another material, something is going to happen. This is where the danger lies. If sulfuric acid comes in contact with any part of your body, rapid destruction of tissue takes place, capable of causing severe burns. When a burn occurs, it also gives rise to the possibility of secondary problems such...

How to Choose a Ladder Most fatal falls in the workplace are from ladders.  Choosing the correct ladder for your work tasks is an important part of your ladder safety program that should include training, proper maintenance and storage, inspections, and safe work procedures. First, assess the height of your work task.  Stepstools and short ladders elevate you slightly.  Stepladders and extension ladders can get you to further heights.  What type of work will you be doing?  Is the ladder used to enter and exit a work area, or will you be working from it?  Platform ladders and work platforms provide stable,...

Near Miss - The One That Almost Happened What is a "near miss?" Webster defines it as: "A result that is nearly, but not quite, successful." What does this mean to the industry? It simply means that a serious accident almost occurred. Someone trips over a pallet but doesn't fall. Two forklifts almost collide in a corner. A tool is dropped, but toes are missed…this time. Statistics tell us that for every 300 near misses there is one serious injury. According to the Bureau of Labor Statistics (BLS), 6.1 million injuries occurred during 1995. If we multiply each injury by 300, the...

Aerial Lifts - Working at Elevations Injuries from falls are one of the most common and severe workplace accidents. Employees must understand how to identify fall hazards and the ways they can protect themselves. Areas Where Fall Hazards Exist: Any height greater than 4 feet is considered a hazard and must be protected. This includes: Roofs Floor Openings              · Loading Docks               · Work Platforms   Ways to Protect Employees from Fall Hazards: The most effective way to protect employees from falls is by eliminating the hazard. Passive systems such as guardrails and covers remove the employee’s exposure to the hazard.   Passive Systems Administrative Controls Active Systems Guardrails Covers Boundary Lines Signs / Access Control Fall...

Health & Safety - Heat Stress Disorders Although summer heat is the largest cause of heat stress disorder, it may also occur when workers are exposed to confined areas such as pipelines, shipboard spaces with limited ventilation, and any confined area involving welding or cutting. Symptoms The symptoms of heat stress disorders are very slow to start, but increase in intensity if precautions are not taken. The onset of the initial symptoms are mild and usually involve headaches, thirst, and tiredness. Heat stress can move to heat stroke, a life-threatening medical emergency, quickly when the body's natural cooling system breaks down and causes the...

Sleep Deprivation Whether it’s due to workloads, or working side jobs, the result is the same – sleep deprivation. Many workers are arriving on the job overly tired or sleep-deprived. Sleep deprivation or fatigue can affect a worker’s manual dexterity, reaction time, and alertness. Worker fatigue or lack of sleep can affect judgment and safety. And workers aren’t the only ones suffering the consequences of sleepiness on the job it’s costing employers money and, in some cases, putting the public’s safety at risk. Studies show that workers are not only getting less sleep than they should; they’re getting less than they used...
