Wear protection

This is a very important topic and will be covered again in Section 2.3.6.5. and more fully in Section 2.4.9. [Pg.33]

Various levels and grades of wear protection may be applied to the conveyor depending upon the application. The main areas on the conveyor requiring protection are the feed zone, flight scrolling surfaces and the flight tips. Mechanically interchangeable wear inserts are more economical to replace than welded or bonded wear protection. [Pg.33]


Corrosion and anti-wear protection Anti-corrosion and anti-wear power High viscosity at high shear rates... [Pg.282]

Personnel who handle phenol should wear protective clothing, safety goggles, and mbber gloves, depending on the working conditions and amount of phenol handled. [Pg.291]

Mech nic l Impact Mills. The mechanical types include cmshers, hammer mills, pin disk mills, turbine mills, and mills with air classifiers. Impact Crusher. Feed material is introduced through a feed opening onto a rotor moving at between 25 and 50 m/s (Fig. 11). The initial impact by the rotor causes some size reduction, and the material is accelerated up to the speed of the rotor and flung against the impact plates, where further size reduction occurs. It is possible to wear-protect these units quite well, so that abrasive materials can be handled. The final end particle size can be varied by the inclusion of an outlet grid to vary the residence time in the machine. [Pg.143]

Because dimethyl sulfate looks like water, operations are preferably not performed when water is present, eg, wet floors or rain. Any spills or leaks should not be left unattended they should be contained, and mnoff to sewers should be avoided. Minor spills should be flooded with water to dilute and hydroly2e the dimethyl sulfate. The area should then be covered with a dilute (2—5 wt %) caustic solution or a dilute (2—5 wt %) ammonia solution, or soda ash may be sprinkled over the neat liquid and the mix wetted with a gende spray of water. The neutrafi2ing agent should remain on the affected area for 24 h and then should be washed away. Only personnel wearing protective equipment should perform these operations. The product bulletins should be consulted for procedures to be followed for more severe spills. Concentrated ammonia should not be used with neat dimethyl sulfate because explosions have resulted after their contact (128). [Pg.202]

Certain compounds found in some coal-tar and petroleum pitches are carcinogenic. Individuals working with pitches or exposed to fumes or dust should wear protective clothing to avoid skin contact. Respirators should be worn when pitch dust or fume concentrations in the air are above estabHshed limits. [Pg.499]

Most carrier-active compounds ate based on aromatic chemicals with characteristic odor. An exception is the phthalate esters, which are often preferred when ambient odor is objectionable or residual odor on the fabric caimot be tolerated. The toxicity of carrier-active compounds and of their ultimate compositions varies with the chemical or chemicals involved. The environment surrounding the dyeing equipment where carriers are used should always be weU-ventilated, and operators should wear protective clothing (eg, mbber gloves, aprons, and safety glasses or face shields, and possibly an appropriate respirator). Specific handling information can be obtained from the suppHer or manufacturer. [Pg.268]

Multilayered structures play an important role in the production of, e.g., biomaterials, catalysts, corrosion protectors, detectors/diodes, gas and humidity sensors, integral circuits, optical parts, solar cells, and wear protection materials. One of the most sophisticated developments is a head-up-display (HUD) for cars, consisting of a polycarbonate substrate and a series of the layers Cr (25 nm), A1 (150 nm), SiO, (55 nm), TiO, (31 nm), and SiO, (8 nm). Such systems should be characterized by non-destructive analytical methods. [Pg.411]

Wear protective clothing which avoids the possibility of cryogenic liquid becoming trapped near the skin avoid turnups and pockets and wear trousers over boots, not tucked in. [Pg.260]

O Do employees wear protective clothing, such as masks ... [Pg.376]

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. [Pg.127]

Are the rules, such as wearing protective clothing, really necessary See Section 1.4.2 (a). [Pg.79]

For a number of years HF-A oiTin-water emulsions have been used as a fire-resistant hydraulic medium for pit props. Concern over maintenance costs and operational life has created interest in a better anti-wear type fluid. Micro-emulsions are known to give better wear protection... [Pg.864]

Doxycycline This drug can cause photosensitivity. Even relatively brief exposure to sunlight may cause sunburn. Avoid exposure to die sun by wearing protective clodiing (eg, long-sleeved shirts and wide-brimmed hats) and by using a sunscreen. [Pg.145]

This drug may cause photosensitivity. Take protective measures (eg, use sunscreens, wear protective clothing) when exposed to ultraviolet light or sunlight until tolerance is determined. [Pg.263]

Gentamicin may cause photosensitivity. Take measures to protect the skin from ultraviolet rays (eg, wear protective clothing and use a sunscreen when out in the sun). [Pg.614]

Caution Contact with 2-bromoallylamine can cause severe eye and skin irritation. This preparation should he carried out in a good hood, and the operator should wear protective goggles and rubber gloves. [Pg.6]

Wear protective gloves and clean body-covering clothing. [Pg.281]

Surface wear is defined as the deformation and loss of surface material as the result of a mechanical, thermal, or chemical action. These three mechanisms can act singly but are more often found in combination, which may make the wear process very difficult to analyze. Materials for wear protection have different responses to each of these wear mechanisms and, consequently, no universal wear material exists. To select the optimum material or combination of materials, it is essential to determine the cause and the mechanism of the wear as accurately as possible. The selection can then be made of the best and most cost-effective material. [Pg.427]

Multilayer coatings or hlms have been proven to be successful in various applications, especially for wear protection. In multilayer systems, the intrinsic stress can be effectively reduced by designing interface number and composite materials in terms of the application and process technique. Therefore, the multilayer technique by which a specihe functional composite is able to approach received more attention for many years [17,18]. Here we introduce the results on microscale friction and scratch of DLC/DLC and Fe-N/TiN multilayers. [Pg.200]

Prior to the advent of the use of highly loaded sihca compounds the wear protection of mbber extmsion screws was virtually covered by either the nitriding or the steUiting process. [Pg.1014]

This is why companies like Berstorff use PVD-coated screws for this purpose as they exhibit better wear protection than screws with nitrided or stellited surfaces. PVD stands for physical vapor deposition and refers to the evaporation of chrome and its accelerated application onto the surface. In combination with nitrogenous gases, the metal ions form hard nitrides that multiply the wear resistance of the screws. [Pg.1014]

False. An element of risk can make a sport very exciting. However, it is necessary to understand the nature of that risk and take action to control it, e.g. wearing protective clothing. [Pg.56]

Masses are determined using balances that compare two forces, (a) Delicatessen balance, b) Students wearing protective glasses while using analytical balance. [Pg.28]

Wear protective clothing such as rubber or plastic aprons, rubber gloves, gas-tight goggles and respiratory equipment as appropriate. [Pg.286]

Wear protective clothing appropriate to fee work, e.g. leather gloves, fire-retardant overalls, safety shoes or boots and eye protection. [Pg.302]

Occasionally, hand exposure must be tested while wearing protective gloves. This may be easily accomplished by wearing the protective gloves over the top of the cotton gloves. [Pg.1004]

Wear protective footwear in public showers and pool areas. [Pg.1207]
