Hand tool safety

General Safety Tips for Hand and Power Tools • Inspect tools prior to use and regularly following manufacturer ​ (a)   . Remove from service and tagout damaged tools. • Select and use tools that are appropriate for the task. Never use tools for purposes other than what the manufacturer intended. • Ensure tools meet all guarding and ​ (b)   standards. Never bypass guards or use tools with broken or missing guards. • Dress appropriately. Avoid wearing loose jewelry and clothing, including ties, scarves, and loose sleeves, which can get caught in moving parts. Wear closed-toe shoes and long pants. Long hair must be tied up and secured (not hanging). • Wear appropriate​ (c)   protective equipment (PPE). Eye protection is essential. Additional PPE may be necessary following an assessment. Contact EHS for assistance. • Secure work pieces to prevent movement and to keep body parts away from the point of operation. • Keep tools and the work area clean. Ensure the floor is dry and clean to avoid tripping or slipping while working with or around tools. Do not work with oily or greasy hands/tools. Ensure the walking working surface is ​ (d)   . • Verify sufficient space is available for the task. Be aware of bystanders and make sure they stay clear of the operation. Workers carrying large tools or equipment on their shoulders should pay close attention to clearances when turning and maneuvering around the workplace. Use screens/barriers to protect bystanders, when necessary. • Avoid leaving tools on elevated surfaces such as ladders and ​ (e)   where they could present a hazard to personnel below. • Use a hoist or suitable tool bag to carry tools when ascending and descending ladders. Never carry tools which inhibit safe use of a ladder. • Exercise care when handing tools to another worker. N

Match the follThe GFCI At Work And Home

Definition: GFCI = Ground Fault Circuit Interrupter. The GFCI is a fast-acting circuit ​ (a)   that senses small imbalances in an electrical circuit caused by the electrical current leaking to ground. If this imbalance occurs, the GFCI shuts off the electricity within a fraction of a second.

How it works: The GFCI device continually matches the amount of ​ (b)   going to an electrical device against the amount of current returning from the device along the electrical circuit path. Whenever the amount “going” differs from the amount “returning” by approximately 5 milliamps, the GFCI interrupts the electric power by closing the circuit within as little as 1/40 of a second.

What a GFCI Can and Can Not do: It does provide protection against the grounding fault–which is the most common form of electrical shock hazard. A grounding fault occurs when a “hot” wire comes into contact with a grounded enclosure. If you happen to be in contact with the grounded enclosure of an electrical tool when a ground fault occurs, you will be subject to a shock unless a GFCI device is in use, and functioning as intended. The GFCI will not protect you from ​ (c)   contact hazards (i.e., holding two “hot” wires or a hot and a neutral wire in each hand).

Where GFCIs are needed in construction work: Your employer is required to provide approved ground-fault circuit interrupters for all 120-volt, single phase, 15-and 20-ampere receptacle outlets being used on construction sites that are not a part of the permanent wiring of the building or structure. Since extension cords are not part of the permanent wiring, any electrical tools or equipment plugged into extension cords must be protected by a GFCI device. Insulation around flexible extension cord conductors can be damaged through hard usage or excessive wear. If the “hot” wire conductor of the extension cord were to come into contact with the grounding wire conductor, a ground fault would occur. GFCIs should certainly be used in wet environments. When a cord connector is wet, hazardous current leakage can occur to the ​ (d)   conductor and to anyone who picks up that connector if they also provide a path to ground. An alternative method of protection is the Assured Equipment Grounding Program. This method is achieved by establishing a direct ground for the equipment and doing a continuity check of the equipment and cords being used.

Where GFCIs are needed at home: The shock hazards of a groun​ (e)   ing fault are not isolated to just your workplace. A grounding fault may occur at home in areas such as bathrooms, kitchens, garages, and basements. You need to be vigilant and make sure that the circuits you are “plugged” into are protected by GFCIs whenever using electrical tools or equipment in potentially wet environments. Most local building codes require receptacles in potentially wet locations, such as near sinks in bathrooms and kitchens, to be equipped with a GFCI device. It is also recommended that you use a GFCI device whenever you have any concerns about the integrity of the tool, equipment, or cord system.owing

Hand injuries account for (a)   of all occupational injuries. This is because the hands are engaged in almost all activities on the job. Can you imagine any occupation that does not make use of the hand? Hands are so important because of their (b)   . They provide us with the dexterity needed to perform most daily activities. In fact, hands, as tools, are so versatile and can perform many intricate functions more than any single known tool developed by man. No wonder hands are highly useful in our jobs. There are many dangerous conditions on the job to which the hand is always exposed. Sharp edges,​ (c)   , protruding objects, splinters, exposed blades on unguarded machinery and many more. These conditions may not always be too obvious to the working person. hand injuriesPinch points are basically traps for the hand especially. Doors may pinch your fingers if you get them caught in a jam. Paying attention and being aware of their existence helps us to avoid pinch points. We also need to take the proper precautions to avoid being pinched. Our hands are also subject to cuts, bruises, burns and poking. Handling sharp objects, hot objects, rough materials and splinters without the necessary hand protection are sure signs of invitation for hand injury. A necessary precaution to take is to wear approved work gloves. Not all gloves protect you from all hand injuries. Check the appropriateness of the glove for the task before using them. Precautions must still be taken to reduce the level of danger before handling very dangerous material. Lockout machinery and power before reaching into them. Check and clear doorways and aisles and make sure you have proper head clearance before you move loads through. Machines are guarded to avoid accidental exposure of their moving parts to the hands and parts of the body. Make sure machines are guarded at all times. Do not wear ​ (d)   or wedding bands when working with machinery. Do not pick up broken glass or spilled machine parts with your bare hands. Remember your hands will obey any commands your brain sends them. Use your ​ (e)   . Avoid dangers and protect your hands. You need them as long as you live.
