A break in an electric tool’s or machine’s insulation can cause its metal parts to become “hot” or energized, meaning that they conduct electricity. Touching these energized parts can result in an electric shock, burn or electrocution.
When can you use the cross bracing given on the rear?
Cross-bracing on the rear section of stepladders shall not be used for climbing unless the ladders are designed and provided with steps for climbing on both front and rear sections.
When going up or down a ladder workers should do all of the following?
Use ladders equipped with nonconductive side rails if the worker or the ladder could contact exposed energized electrical equipment. Face the ladder when moving up or down. Use at least one hand to grasp the ladder when climbing. Do not carry objects or loads that could cause loss of balance and falling.
What must employers do to tools regularly?
Make sure employees have and use safe tools and equipment and properly maintain this equipment. Use color codes, posters, labels or signs to warn employees of potential hazards. Establish or update operating procedures and communicate them so that employees follow safety and health requirements.
Who is covered by the OSH Act final exam?
Who is covered? In general, coverage of the OSH Act extends to all employers and their employees in the 50 states, the District of Columbia, Puerto Rico, and all other territories under federal government jurisdiction.
When there is a break in an electric tools insulation or wiring the tools metal parts may become _?
A break in an electric tool’s or machine’s insulation can cause its metal parts to become “hot” or energized, meaning that they conduct electricity. Touching these energized parts can result in an electrical shock, burn, or electrocution.
When there is a break in electric tools insulation or wiring the tools metal parts may become?
Metallic parts of electric tools and machines can become energized if there is a break in the insulation of their wiring. A low-resistance wire between the metallic case of the tool/machine and the ground – an equipment grounding conductor – provides a path for the unwanted current to pass directly to the ground.
When set up the base of the ladder should always be?
When a ladder is leaned against a wall, the bottom of the ladder should be one-quarter of the ladder’s working length away from the wall. For access to an elevated work surface, extend the top of the ladder three feet above that surface or secure the ladder at its top.
What should you do when you use a ladder OSHA quizlet?
BE sure to use ladders safely by choosing the right ladder for the job, tying the top and bottom of the ladder to fixed points when necessary and keeping your hands free and always maintaining three points of contact with the ladder while climbing. Remember to never use the top of a step ladder as a step.
When working with electrical equipment only the following types of ladders shall be used?
Only choose ladders with the UL (Underwriter’s Laboratory) seal. Ladders are made of one of three materials: wood, aluminum, or fiberglass. Aluminum ladders are dangerous around electricity because they conduct electricity, although it is the least likely to break down over years of use.
What is the most serious hazard when working with electric tools?
Among the most serious hazards are electrical b urns and shocks. Electrical shocks, which can lead to injuries such as heart f ailure and burns, are among the major hazards associated with electric- powered tools.
What are some general OSHA guidelines to use when using power electric tools or other hand tools in the workplace?
To prevent hazards associated with the use of power tools, OSHA recommends that workers should observe the following general precautions: Never carry a tool by the cord or hose. Never yank the cord or the hose to disconnect it from the receptacle. Keep cords and hoses away from heat, oil, and sharp edges.
When working with hand and power tools you should always?
Keep floors dry and clean to avoid slipping while working with or around dangerous tools. Keep cords from presenting a tripping hazard. Never carry a power tool by its cord. Use tools that are double-insulated or have a three-pronged cord and are plugged into a grounded receptacle.
What is OSHA’s main purpose?
With the Occupational Safety and Health Act of 1970, Congress created the Occupational Safety and Health Administration (OSHA) to ensure safe and healthful working conditions for workers by setting and enforcing standards and by providing training, outreach, education and assistance.
What are the 3 phases of an OSHA inspection?
An OSHA inspection, whether programmed or unprogrammed, consists of three stages: Opening Conference; Walkaround or Full Company Inspection, Document Review and Employee Interviews; and. Closing Conference.
What is the difference between OSH and OSHA?
Question: What are OSHA and OSH? It was created by the Occupational Safety and Health Act (OSH) enacted in 1970. OSHA is responsible for enforcing and administering the OSH, which contains a wide range of protections designed to help prevent workplace accidents and keep employees safe.
How often do electrocutions occur in the United States?
Statistics tell us that there are over 400 electrocutions and over 4000 non-fatal injuries every year in the United States. That is more than one death each day of the week across the country. And some 40% of those are from or related to products and equipment in the home.
Which circuit interrupts most effective?
Which one of the following circuit interrupts is most effective at preventing major shocks? GFCI is the right answer because others cannot shut down electricity immediately.
What are the two outcomes to an electric shock?
An electric shock may directly cause death in three ways: paralysis of the breathing centre in the brain, paralysis of the heart, or ventricular fibrillation (uncontrolled, extremely rapid twitching of the heart muscle).
What might happen if the plastic or rubber covering on wires was damaged or broken?
Extension cords may have damaged insulation. Sometimes the insulation inside an electrical tool or appliance is damaged. When insulation is damaged, exposed metal parts may become energized if a live wire inside touches them. You are more likely to receive a shock if the tool is not grounded or double-insulated.
What will happen when you touch exposed electrical wire or a piece of electrical equipment?
Coming in contact with an electrical voltage can cause current to flow through the body, resulting in electrical shock and burns. Serious injury or even death may occur.
What is the name of the hazard if wire is open?
A plug or electrical cord should not have exposed wiring. Exposed wires present a danger of electric shock or electrocution. Using an open front plug poses the risk of contact with live wires when plugging it to a electrical outlet. This also poses a risk of electric shock or electrocution.
