Electricity power tools

Hot Work. The objective of a hot work standard is to prevent fires, explosions, and other causes of injury which might result from workplace ignition sources such as welding (qv), cutting, grinding, and use of electrically powered tools. The OSHA standards have specific requirements (36,94) for fire prevention and protection and a permit system. [Pg.100]

As one of thousands of examples, in the fall of 1987, Milwaukee Electric Tool Corp. found itself on the short end of the age-old supply-and-demand equation. That is, it was unable to keep up with demand for its heavy-duty electric power tools. The problem was that their machining operations could not turn out... [Pg.34]

If you can answer yes to the above points then the risks are adequately controlled, but you need to state the precautions you have put in place. You can refer to company procedures, company rules, company practices, etc. in giving this information. For example, if we consider there might be a risk of electric shock from using electrical power tools, then the risk of a shock will be less if the company policy is to portable appliance test (PAT) all power tools each year and to fit a label to the tool showing that it has been tested for electrical safety. [Pg.26]

It is particularly important to check that the plug top and cables of handheld electrically powered tools and extension leads are in good condition. Damaged plug tops and cables must be repaired before you use them. All electrical power tools of 110 and 230 V must be tested with a portable appliance tester (PAT) in accordance with the company s health and safety procedures, but probably at least once each year.

Key hazards of electric-powered tools include burns and slight shocks that can lead to injuries or heart failure. To protect users from shock, tools must contain a three-wire cord with a proper ground. Tools can also contain double insulation or powered by a low-voltage isolation transformer. Operate electric tools within their design limitations. Recommend use of gloves and safety footwear when using electric tools. Never use electric tools in damp or wet locations. Keep work areas well lighted. [Pg.103]

Employees using electric tools must be aware of several dangers the most serious is the possibility of electrocution. Among the chief hazards of electric-powered tools... [Pg.449]

Q. 1 Must electric power tools be either double insulated (plug without grounding prong) or grounded ... [Pg.1393]

A. 1 Yes, but there are some limitations to choosing the double insulation option. Section 1926.404(f)(7)(iv) states that electric power tools must be grounded except when they are double insulated. The standard allows double insulation instead of grounding within certain limitations double insulated tools are not to be used in a hazardous location and must not to be operated at over 150 volts to ground. Also, double insulated tools must be distinctively marked. [Pg.1393]

The Elastogran GmbH subsidiary of BASF is a specialist producer of PU which in its soft, plasticiser-free formulation is a popular material for the handles of electric power tools, laptop computers and mobile phones, because, whilst remaining tough, it is relatively soft to the touch. [Pg.86]

Electrically powered tools and equipment and lighting used in damp confined spaces must be connected to a ground fault circuit interrupter (GFCI). [Pg.75]

The need to operate electrically powered tools or devices independently of stationary power sources has led to the development of a variety of different battery systems, the preference for any particular system depending on the field of application. In the case of a occasional use, for example, for electric torches in the household or for long-term applications with low current consumption such as watches or pacemaker, primary cells (zinc-carbon, alkaline manganese, or lithium-iodide cells) are chosen. For many other applications such as notebooks, MP3-players, cellular phones, or starter batteries in cars only rechargeable battery systems, for example, lithium-ion batteries or lead-acid batteries, can be considered from the point of view of cost and the environment.
