Cutting hazards

The edges and comers of enclosures shall be rounded or smoothed to prevent cutting hazards to operators. Furthermore, enclosures, handles, knobs, and the like shall have adequate strength to withstand rough handling during normal use and pass the relevant tests as described in the standards. Depending on the product and possible hazards the tests may include force tests, steel ball impact test, and drop tests (refer to standards). 

Falling objects create a major hazard for feet. There are hazards also from slipping. There are hazards from stepping on protruding nails or objects and from hot materials, wet materials, and contact with chemicals. There are also cutting hazards of tools, such as axes and chainsaws. There are dangers from cold exposures and from hot work. 

Employers must provide body protection for employees if they are threatened with bodily injury of one kind or another while performing their jobs, and if engineering, work practices, and administrative controls have failed to eliminate snch hazards. Workplace hazards that conld canse bodily injury include intense heat splashes of hot metals and other hot liqnids impacts from tools, machinery, and materials cuts hazardous chemicals contact with potentially infections materials such as blood or radiation. 

Workers were using leather driver s gloves for jobs that involved cut hazards, such as changing blades on packing line equipment and working with utility knives in warehousing applications. These practices resulted in many near misses and some injuries, with a number of workers indicating they lacked confidence in their ability to safely perform their jobs. 

Has safe access been provided to the equipment that requires operator and calibration and maintenance personnel access for normal operations, adjustments, service, calibration, maintenance or repair Have slip, trip, trap, crush, entanglement, fall, bump and cut hazards been minimized ... 

Welding and Cutting. Hazards include ignition of combustibles by the arc or flame itself, heat conduction through the metals being welded or cut, molten slag and metal from the cut,... 

Conpared with the conventional types the numerically controlled machine tools are marked by certain characteristic risk factors. They are typically associated with entangling and cutting hazards caused by unexpected machine movenents or hazards of flying objects in collisions. The potentiality of these hazards has grown for the following reasons ... 

CartonCutter gloves provide comfort and protection in warehouse operations where cut hazards often occur. These cut-resistant gloves can be worn on either hand, making them ideal for use as opposite hand cut gloves. For more information, call Banom at 800-227-7694 or visit our website at banom.com. Circle 330... 

We are unique in our belief that there are three types of cut hazards ... 

Banom supplies end-use customers through a limited group of distributors that have been specifically trained to handle cut hazard problems. Working in conjunction with our distributors, Banom has a consistent track record of reducing laceration rates as well as total spend. 

Great choice for outdoor mechanical maintenance where cut hazards exist. 

Miscellaneous Natural Abrasives. Powdered feldspar [68476-25-5] is used as a mild abrasive in cleansing powders, and clays are sometimes used in polishing powders. StauroHte [12182-56-8] is a complex hydrated aluminosiHcate of kon, of high density (3.74—3.83 g/mL) and a hardness of 7 to 8 on Mohs scale. It is primarily used as a sandblasting grit, but siHcosis hazards had cut production in 1987 about 25% compared to that... 

The highest G-ratios are obtained when grinding with straight oil coolants. Such oils reduce power, increase maximum depth of cut, and produce smoother finishes. Disadvantages include inabiUty to remove heat from the work, oil mist in the work area, fire hazard, and tendency to hold grinding swarf (fine metal chips and abrasive particles produced in the grinding process) in suspension. Reference 51 is an excellent survey article for grinding fluids. 

The rolling operations that foUow take place first on hot (95°C) differential-speed roUs which dry and coUoid the paste and convert it iato sheet form, and then on even-speed roUs which produce smoothly surfaced propellant sheets ia which all iagredients have been uniformly iacorporated. The roU gap ia the differeatial roUs is adjustable to produce sheets of various thicknesses, and rolling is continued until the moisture is reduced to a predetermined level, usually less than 0.5%. The sheet is then cut off the roU. Differential rolling is potentially hazardous, and fires are not uncommon, although detonations are not apt to occur. Operations are conducted by remote control.

Because self-regulating heaters are parallel heaters, they may be cut to length at any point without changing their power output per unit of length. This makes them much easier to deal with in the field. They may Be terminated, teed, or spliced in the field with hazardous-area-approved components.

The new hand protection standard resulted from OSHA s belief that many hand injuries result from not wearing hand protection or wearing protection for the wrong type of hazards. Employers should evaluate and provide hand protection when there are hazards to hands from absorption of harmful substances, severe cuts or lacerations, severe abrasions, punctures, chemical burns, thermal burns, and harmful temperature extremes. 

The fire department blamed the accident on welders cutting in hazardous areas without a fire watch, highly combustible structural components (fiber-glass-resin), high-density storage of highly flammable and detonable material, spilled ammonium perchlorate about the plant, and high w ind conditions. 

An old pipeline, no longer used, was marked with chalk at the point at which it was to be cut. Before the mechanic could start work, heavy rain washed off the chalk mark. The mechanic "remembered" where the chalk mark had been and he was found cutting his way with a hacksaw through a line containing a hazardous chemical. 

In this study detailed fault trees with probability and failure rate calculations were generated for the events (1) Fatality due to Explosion, Fire, Toxic Release or Asphyxiation at the Process Development Unit (PDU) Coal Gasification Process and (2) Loss of Availability of the PDU. The fault trees for the PDU were synthesized by Design Sciences, Inc., and then subjected to multiple reviews by Combustion Engineering. The steps involved in hazard identification and evaluation, fault tree generation, probability assessment, and design alteration are presented in the main body of this report. The fault trees, cut sets, failure rate data and unavailability calculations are included as attachments to this report. Although both safety and reliability trees have been constructed for the PDU, the verification and analysis of these trees were not completed as a result of the curtailment of the demonstration plant project. Certain items not completed for the PDU risk and reliability assessment are listed.
