# ARC FLASH HAZARDS (cont.) ## HOW CAN YOU PROTECT YOURSELF FROM THE HAZARDS OF ARC FLASH? (cont.) • De-energizing would create a more significant hazard, or it is necessary for the interests of health and safety that the electrical work is carried out while the equipment is energized (e.g., it may be required for life-saving equipment to remain energized and operating while electrical work is carried out on the equipment). • It is necessary that the electrical equipment to be worked on is energized for the work to be carried out correctly. • It is necessary for testing or troubleshooting. • There is no reasonable alternative means of carrying out the work. ## NOTE: USE APPROPRIATE LOCKOUT, TAGOUT, AND HAZARDOUS ENERGY CONTROL PROCEDURES TO ISOLATE ENERGIZED EQUIPMENT WHEN A CIRCUIT BREAKER OR OTHER DISCONNECT TURNED OFF. THE BEST ARC FLASH PROTECTION IS TO DE-ENERGIZE EQUIPMENT BEFORE WORKING ON IT! IS Second Best Choice for Arc Flash Protection: Use appropriately rated personal protective equipment (PPE). Arc flash personal protective equipment (PPE) is a combination of clothing and safety equipment worn for protection from arc flash and shock hazards by a person performing electrical work. Primarily, arc flash PPE is divided into the following subgroups: • Head, face, neck, and chin protection • Eye protection • Hearing protection • Body protection • Hand and arm protection • Foot and leg protection ## GENERAL ELECTRICAL SAFE WORK PRACTICES All employees working on or near electrical equipment shall follow general safe work practices, including: • Maintain housekeeping procedures in the work area, e.g., prevent slip trips and falls; eliminate fire hazards; control dust; prevent falling hazards; clear clutter. • Plan and analyze each step of a work task to ensure safety. • - Maintain appropriate work boundaries for qualified electrical workers (QEW) and unqualified workers. • Use properly rated and tested test equipment (e.g., multimeter). …

# Authorized and affected employees - An "authorized employee" is a person who has been properly trained to lockout/tagout procedures on machinery or equipment that is to be serviced. - An "affected employee" is a person who operates the machinery or equipment, but does not perform the lockout procedures, or a person who works in the area where machine or equipment maintenance is being done.

# LOCK OUT TAG OUT (LOTO) (cont.) ## LOTO STEPS Prepare for Shutdown: An authorized employee must identify the type of energy, understand the hazards of the energy, and the methods to control the energy before using the LOTO procedure. • Notify Affected Workers: Notify all affected employees that energy will be shut down and locked out for service or maintenance. • Shut down the Tool or Equipment: Shut down the tool or equipment. Follow the details provided in the lockout/tagout procedure. Many tools or equipment have complex, multistep shutdown processes, so following the directions precisely as the procedure lists them is essential. - Disconnect or Isolate the Tool or Equipment: Completely isolate the machine or equipment from its energy sources by using the appropriate energy-isolating devices. - Apply Lock(s) and Tag(s) to the Energy Isolating Device(s): Apply unique lockout/tagout devices to the power sources. - Dissipate Stored Energy: Dissipate stored and residual energy, such as that in capacitors, springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure. - Check for Stored Energy: Check the tool or equipment for stored or residual energy. Testing instruments, such as voltage detectors or pressure gauges, can be used to confirm energy isolation. These instruments should be calibrated, adequately maintained, and used according to manufacturer instructions. • Restoration: Restoration is the final step in the LOTO safety and procedures. It involves inspecting the work area for completion and safety, removing LOTO devices properly, informing affected employees of equipment status, and restarting. Before restoring equipment, the work area must be inspected for completion and safety. This may involve verifying that all tools and equipment have been removed from the equipment and that the work area is clean and debris-free. ## RESOURCES Chapter 296-803 WAC-Lockout Tagout WAC [redacted identifier]-L…

# LOCK OUT TAG OUT (LOTO) DANGER LOCKED OUT DO NOT REMOVE DAN ER DON IT OPER Date Posted: 05/29/2024 The release of uncontrolled energy causes thousands of injuries each year. Each year, approximately 3,000 workers suffer lost-time injuries from being caught in dangerous parts of equipment or machinery during maintenance or cleaning, according to Bureau of Labor Statistics (BLS) data. Further, each year, there are approximately 60 fatalities from similar exposures. ## WHAT IS LOTO? A lockout tag-out (LOTO) is a set of safety procedures to prevent personal injury or property damage when working with, near, or on machines, tools, or equipment. Also called LOTO procedures, they involve manually adding locks and tags to parts of machines to make all employees aware of the maintenance work and prevent accidents. Employees involved in the lockout tag-out place locks on machines to prevent others from turning the machine on, and they place tags as warning signs of the current maintenance. LOTO aims to protect workers from accidental injury or death caused by unexpected equipment start-up or the release of stored energy. At the same time, maintenance or servicing is performed. The procedure involves locking or tagging the equipment's energy-isolating devices, such as switches or valves, and preventing the release of hazardous energy until the work is completed and the equipment is deemed safe to operate again. ## What Sorts of Energy Should I be Concerned about in Construction? According to the Occupational Safety and Health Administration (OSHA), Energy sources, including electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other sources in machines and equipment, can be hazardous to workers. During the servicing and maintenance of machines and equipment, the unexpected startup or release of stored energy can result in severe injury or death to workers. Kinetic and potential are two encompassing forms of energy prevalent in the construction industry…
