The theme for February’s Health and Safety guidance is Electricity on Site.
Construction sites electricity poses a unique hazard to construction workers. Unlike other dangers, electricity cannot be seen, heard, or smelled. Electricity can only be felt and by the time that electricity is felt, it is too late to protect oneself from harm. Although electricity can cause many different types of injuries, the three types of injuries that most commonly occur on construction sites are the following:
- death by electrocution or severe internal and/or external burns through inadvertent contact with high voltage lines or equipment.
- severe burns or death from explosive gases inadvertently ignited by electrical equipment.
- various injuries from falls or from contact with moving equipment that occurs after a worker experiences a low voltage electrical shock and can no longer safely maintain his/her balance or physical control of the tools or equipment that he or she was manipulating when shocked.
