Electrical Hazards - Anatomy Of An Accident A crew of four linemen were installing intermediate poles on an existing single phase 14.4 KV distribution line. Three of the workers were journeymen with 30 or more years of experience. The fourth was an apprentice with almost 3 years experience. The following summary describes a tragic accident: One of the journeymen and the apprentice were belted off below the neutral bracket on a newly installed pole, using hot sticks to tie off the energized conductor. Another journeymen on the ground was using a hold-down to keep the conductor in place while the wrap-lock...

Portable Electric Tools The use of portable electric power tools is one of the most common occurrences on a construction project today. Workers are exposed to the use of these tools constantly. It is important to remember that electricity always seeks a path of least resistance and often that is through a defective cord into the worker’s body. This is especially true if the worker is exposed to wet weather or has been sweating. Guide for Discussion The following safety rules should be reviewed when discussing the safe use of portable electric tools: Use only equipment that is in good condition. Be sure the...

Electrical Hazards Electrical hazards are doubly hazardous in that there is not only the chance of electrocution, but there is also the probability that any electric shock will cause a loss of consciousness that may well result in a fall of some sort. Today we will discuss methods of receiving an electric shock and ways to avoid electrical hazards. Guide for Discussion Methods of Receiving an Electric Shock From a defective power tool. From defective extension cords. From overloading a switch or over-riding a by-pass. By not grounding electrical equipment or using Ground Fault Circuit Interrupters. By coming in close contact with live...

Electricity “Low voltage” does not imply safety Wet conditions can intensify electric current Make sure work-boots are non-conductive Watch for overhead power lines – handle metal studs in a safe manner If a fluorescent light fixture is falling don’t try to catch it Occasionally check power cords and other electrical equipment for wear Only use equipment approved by Underwriters Laboratory or other accrediting agency Wear protective gear Don’t overload circuits ...

Safe Handling of Portable Power Drills Portable power drills are one of our most useful tools and, with care, they can be among the safest.  But electric drills can be dangerous if not handled carefully.  They can cause injuries in many ways – from being struck by flying drilling material, if chips of the materials being drilled are flung into the operator’s eyes or if the bit punctures or bores into flesh (usually a leg), and from electric shock. When drills are treated roughly, dropped or hit against things, or if they get wet, their insulation can weaken.  Without proper insulation you...
