protective gloves

Chemical resistance of



protective gloves

Protective gloves are available in a wide range of natural

and synthetic materials; however, there is no single glove

material (or combination of glove materials) able to provide

unlimited resistance to any individual or combination of

chemical agents. There are three ways in which any

protective glove will, at some stage, fail to protect the

wearer from exposure to any chemical agent and these are:

permeation – the process by which a chemical agent

migrates through the protective glove at a molecular level;

penetration – the bulk flow of a chemical agent through

closures, porous materials, seams and pinholes or other

imperfections in the protective glove;

degradation – a damaging change in one or more

physical properties of the protective glove as a result of

exposure to a chemical agent.

Selecting suitable protective

gloves

The selection of suitable protective gloves is a complicated

procedure and the degree of protection they give is not

always easy to establish. When choosing gloves, always

seek expert help from the manufacturer/distributor of the

chemical agent or glove. They are best placed to provide

you with glove performance test data which can be used

to assist in predicting the permeation, penetration and

degradation of specific glove materials by specific

chemical agents.

There are four requirements which must be met for any

protective glove selected to be suitable. The glove must:

be appropriate for the risk(s) and the conditions where

it is used;

take into account the ergonomic requirements and

state of health of the person wearing it;

fit the wearer correctly, if necessary, after adjustments;

either prevent or control the risk involved without

increasing the overall risk.

Proper selection should therefore take into consideration

the wearer, the workplace conditions and the protective

glove. Employees need to be trained in the correct way

to put on, wear and then take off protective gloves to

ensure maximum protection. There should be adequate

facilities for disposal of contaminated protective gloves.

If protective gloves are selected or worn incorrectly there

is every possibility that this may increase the wearer’s

overall risk to health because:

contaminant may get inside the glove to reside

permanently against the skin which could cause greater

exposure than if a glove had not been worn at all; or,

wearing a glove for extended periods can lead to the

development of excessive moisture (sweat) on the skin

which in itself will act as a skin irritant; or,

wearing gloves manufactured in natural rubber (latex)

can cause an allergenic reaction in susceptible individuals,

causing the skin disease contact urticaria to occur.

Selecting protective gloves must be part of an overall health

and safety risk assessment for the job to be done. The risk

assessment must clearly demonstrate that exposure to the

health and safety risk is unavoidable and that other

methods of control are not reasonably practicable.

Remember that gloves should be used as a control

measure only as a last resort1 and where other methods

of control are not reasonably practicable. This is because:

gloves only protect the wearer – they do not remove

the contaminant from the workplace environment;

some types of glove are inconvenient and interfere

with the way people work;

wearing gloves interferes with the wearer’s sense of

touch;

the extent of protection depends upon good fit and

attention to detail;

if protective gloves are used incorrectly, or badly

maintained, the wearer may receive no protection;

for glove design to be effective, the glove needs to be

used correctly in the workplace.

Because glove selection is a complex issue, employers

and others responsible for selection will inevitably demand

a simple, easy-to-read guide. Table 1 gives a simple guide

to selection to help with glove material choice.

Table 1 recommends the most suitable glove materials

to protect wearers from exposure. The importance of

using a material depends on the extent of exposure. For

chemical groups such as strong acids, only one choice of

glove material is identified as most suitable, whereas a

range of materials may be suitable for other chemical

groups such as weak acids. Where there is a choice of

glove material, the extent of exposure to the chemical

agent will be a significant factor in choosing between, for

example, a neoprene glove or a less costly natural rubber

Baseball Gloves buying guide

Baseball Globes


Through the years, baseball gloves have become far more sophisticated and advanced. A ballplayer in the modern era needs a glove that is unique to the position that he or she plays. There are a variety of decisions to make when choosing a glove. The position that the glove is meant for is extremely important, as well as the glove's durability and ability to withstand damage. Many Companies offer gloves in a variety of price ranges. Generally speaking, more expensive gloves are made with higher quality leather that will last longer. As is with most sporting goods, with baseball gloves you get what you pay for.

Making The Right Choice

Your choice of glove should depend on a few things. Take into consideration your own ability as a player, how often the glove will be used, and the level of competition you will be playing at. If you are the parent of a child who is new to game, their is no need to spend $200 on a glove that is probably better suited for a high school or college ballplayer. You might be better off buying a glove that costs somewhere between $25 and $75 and seeing if your child takes to the game. If you do play competitive baseball, you probably have an idea of your needs as a player. This guide may further assist your decision.


Glove Sizes

Gloves for adults generally range in size from 10 to 13 inches. Different positions require different glove sizes. Children's gloves generally range in size from 8 to 12 inches, are not as position specific and comfort should be emphasized most. A child might be wearing a glove not neccesarily ideal for his or her position, but if they are comfortable, keeping the same glove is probably a safe bet.

Gloves By Position

Outfield gloves: Outfield gloves should generally range in size from 12 to 13 inches. Bigger gloves have bigger pockets and provide more room to catch the ball. This is very important when a player is attempting to catch a fly-ball

Infield gloves: With the exception of the first baseman, Infield gloves are generally smaller and usually range in size from 10 1/2 to 12 inches. Middle infielders, such as the shortstop and second basemen are prone to have the smallest gloves on the field so they are able to turn double plays and get the ball out of their gloves quickly.

Pitcher's gloves : Pitcher's gloves can be any length, but they are usually within the same size range as other infield gloves.

Catcher's mitts : Catcher's mitts look and feel entirely different than any other baseball glove. They have more padding and durability than any of the other gloves. This is probably due to the fact that they take a severe beating day in and day out.

First base gloves : First base gloves are generally larger than any other infield glove. Like catcher's mitts, they have an extra layer of padding, which helps them cope with hard throws from other infielders.


Major Brands

Mizuno : Mizuno provides gloves of all shapes and sizes for players of any ability and/or price range.

Rawlings : Rawlings is a well known and respected company. They have "player series" Gloves for youths that cost as little as $24.99 and "Pro Preferred Gloves" for advanced ballplayers that can cost more than $250.

Wilson : Wilson has been manufacturing gloves since 1922 and is now considered to be one of the premier suppliers for major league gloves. They have 13 different lines of gloves to choose from (5 youth, 8 adult) that can cost as must as $300 and as little as $15.

SSK : SSK is a Japanese company, widely regarded for its high-end gloves. Their gloves generally cost more than $50 and they have a limited number of models available (9). These gloves provide sophistication and durability and are specifically manufactured for the serious ballplayer.

Nike : Baseball gloves are a recent addition to the Nike sporting line and at this point they offer only 2 series of gloves. The "SDR" series gloves generally cost anywhere between $60 and $100 while the "Pro Gold" series gloves are slightly more expensive.

Nokona : Nokona has been making top-of-the line Gloves for more than 70 years. These are quality, pro level gloves that should not even be considered by the novice ballplayer. At the very least, a Nokona will cost you $125.

Akadema : Akadema has been around for less than a decade, but since its inception it has provided a variety of gloves for youths and adults. Prices are reasonable, while quality remains high. Youth gloves can cost as little as $40, while adult gloves rarely exceed $175.

Louisville Slugger : Louisville Slugger is renowned for their superior baseball bat design, but they also have recently manufactured some high quality makes of gloves. You can find some of their youth designs as cheap as $40, while some of their more expensive gloves are in the $150 price range.

Easton : Easton provide a wide variety of gloves for the novice ballplayer. They have adult gloves that cost under $40, and youth gloves that cost under $20.

Glovesmith : With over 50 models and a price range of $19 to $320, Glovesmith can provide a glove for anyone.

Tips for Breaking in Your New Glove

Work in the padding: use both hands to grab the heel of the glove and twist it back and forth. Do the same for the fingers and the thumb of the gloves

Buy some glove conditioning oil. Rub the oil into the inside of the glove a handful of times, spaced out periodically (wait a couple of days between each application). This will soften the glove and decrease the tension within the frame.

When the glove is not in use, place a baseball in the pocket and wrap a rubber band around the outside of the glove. This will allow the ball to adjust to the shape of the glove more easily.

Play catch as frequently as possibly. Throw a ball into your glove repeatedly if you cannot find someone to play catch with. The more times a baseball hits that leather, the quicker your glove will break in.

Glove Maintenance

When not in use, try to store the glove in a cool, dry place. This is especially important for the off-season, when your glove might not receive use for a few months at a time.

If your glove becomes wet or damp, use a towel to dry it. Do not put it in the oven or microwave. Also, never place your glove on top of a heater as it will most likely dry out the leather.

Keep the laces of your glove tight at all times. The more you let them loosen, the more damage gets done to the overall frame of the glove.

Avoid over-oiling your glove. Once you have oiled a new glove a handful of times, you should not oil it more than once or twice a season.

Fingerless Gloves

Fingerless Gloves


By Sarah E. White

Warm Hands, Warm Heart:


Sometimes when it's cold outside, it's also cold inside. If you live or work with people who like it cooler than you do, or if you have chronically cold hands, you need a good pair of fingerless gloves.

These gloves allow you to use all your fingers with ease but still keep the palm of your hand and your thumb warm while you're working. Made from a soft, warm wool, these mitts will keep your hands cozy all day long.

Materials:


•one ball, about 80 yards, of super-chunky wool (I used Rowan Big Wool in Cloak and had a little left over)

•two pairs of size 15 US circular needles

•scissors

•tapestry or yarn needle

•crochet hook

Gauge

Two and a half stitches and three rows per inch knit stockinette stitch in the round.

Size

Finished project is nine inches long and eight inches around.

On a small woman, these gloves cover about half the forearm and go over the whole palm. The thumb is covered to the knuckle. Adjust the length as desired. They fit a small or medium-sized woman with little stretch, but they also stretch enough to fit a medium-sized man.




Instructions for Body:

1.Using the long-tail cast on, cast on 18 stitches using one set of circular needles.

2.Slide the stitches to the other end of the needle and slip the first nine stitches that were cast on onto the second circular needle. Place a stitch marker before the last stitch on the second needle if desired to mark the end of the row.

3.Join in the round, being careful not to twist stitches.

4.Knit in stockinette stitch (knit every row) for about seven inches, or to desired length before thumb. To knit using two circulars, knit the first nine stitches with one set of circular needles and the second stitches with the other set.

Instructions for Thumb :

1.On the next row, knit the first six stitches on the first needle, then slip the last three stitches from that needle and the first three stitches from the second needle onto a stitch holder. Knit the last six stitches, remembering to pull tight when you switch needles.

2.Continue to knit in the round on 12 stitches for two inches or to desired length.

3.Bind off loosely. Cut yarn.

4.Slide three stitches off your stitch marker onto one needle and three stitches onto the other needle. Knit these six stitches in the round one and a half inches or to desired length. Bind off loosely. Cut yarn, leaving a long tail.

Finishing:

1.Use a tapestry or yarn needle and the long tail to sew up any hole that appears between the thumb and the hand. Weave in ends.

2.Make the second glove in the same manner.

About the Yarn:

Rowan Big Wool is a joy to work with. This bulky, soft, 100 percent merino wool yarn just begs to be made into a project like this that will get a lot of use and keep the wearer very cozy. Because this is merino wool, the yarn has a nice "halo" and is very durable and low on the itch factor.

Because it is fine wool, the manufacturer recommends hand washing in cool water. Do not agitate the fiber. Reshape the garment and allow to air dry out of direct sunlight.

The color I used does not seem to be widely avialable any longer; Tremble would be a good subsitute, or use any of the 28 colors you like.
