Personal Protection Equipment

Helmet

The helmet attempts to protect the user's head against impact with the cutter bar of the chainsaw should a kickback occur. Protection can only be successful if the chain brake has operated to stop the cutter chain as a chain running at full speed can easily cut the helmet. A helmet also protects against impacts from small falling objects, such as a dead branch from a tree being felled.[3]Exposure to the sun will cause the plastic of the helmet to weaken over time so it is recommended that the helmet is replaced every 3-5 years. Helmets commonly have a symbol inside that shows when it was made. Many helmets also now have a sticker that fades with exposure to light.

Visor or goggles.

A visor or goggles reduce the chance of chips penetrating the user's eyes.The relatively flimsy mesh visor, with imperfect coverage of the face, is considered acceptable because the chips produced by well-maintained chainsaws are of relatively uniform size and speed. Unlike other woodworking tools, a chainsaw with a sharp chain produces little or no sawdust, only chips (that are too large to fit through the visor's mesh).Some chainsaw users prefer conventional safety glasses or goggles.[2] The choice may depend on the environment. The visor provides better ventilation for hard work in hot weather. Often, both safety goggles and a visor are employed for superior protection.

Chainsaw safety mitt

A leather mitt for the operator's left hand that is fitted to (but is free to rotate on) the front bar of the chainsaw.The safety mitt ensures that if kickback occurs the operator's hand remains on the bar of the chainsaw. This means that the kickback is more easily controlled and the chain brake is engaged. The safety mitt also protects the operator's left hand in the same way as Chainsaw Safety Gloves.

Ear defenders

Ear defenders and ear plugs attenuate noise to levels that cause little or no damage to the user's hearing.[2][3] Non-electric chainsaws are very loud, typically 115 dB, above therecommended exposure limit of 85 dB from the National Institute for Occupational Safety and Health.

Trousers/Chaps

Special fabrics have been developed for chainsaw clothing, and this development is still very active. Conventional fabric is useless at protecting against a running chainsaw, being immediately cut through.There is a real struggle between making a fabric proof against more violent impact, and making it light, flexible and comfortable enough for the user. Clothes which make the user too hot, or which prevent the user moving easily, are a safety problem in themselves. A worker suffering from heat exhaustion is not safe. Extra fabric layers can be added to clothing to improve cut resistance, but clothes which cannot be cut at all by a powerful saw are impractical, even with modern fibres. What is worse, saw and chain technology seems to be outstripping fabric technology. High power saws with aggressively cutting chains are almost impossible to protect against.A classification scheme has been developed in the EU to rate trousers, and fabric in general, for protection against cutting.Chainsaw Fabric ClassificationClassMax chain speed016 metres per second (36 mph) (3150 feet per minute)120 metres per second (45 mph) (3937 feet per minute)224 metres per second (54 mph) (4724 feet per minute)328 metres per second (63 mph) (5512 feet per minute)The chain speed is specified in the manual for a chainsaw. Higher class trousers cost more and are heavier, so there is an advantage to choosing the trousers to match the saw.There are two standard types of trousers, type A and type C. Type A protects only the front of the legs, and can be supplied as chaps, worn over conventional work clothes, or as conventional trousers. Type C gives protection all round the legs and are almost always worn as ordinary trousers, not over another garment. Chaps are generally used for occasional, farm or homeowner applications.[5] Professional chainsaw operators would choose trousers for comfort and ease of movement, with fallers, ground workers and firewood cutters opting for class A trousers because of the low risk of being cut in the back of the leg. Climbers and tree surgeons would have to wear type C, as they will be cutting from a wider variety of positions. Type C trousers are, of course, highly insulating, and may lead to heat stress if worn for labour intensive operations such as firewood cutting.Chainsaw protective fabric works on a number of principles. The outermost layer can be made both tough and slippery, to protect against trivial damage which could compromise the filler material. Beneath this, long, loose fibres of ballistic nylon or Kevlarare laid in layers. When a saw contacts the trousers, the outer layer is immediately cut through but the nylon or Kevlar is drawn out and wraps around the saw's drive sprocket, locking it solid and halting the chain, limiting damage to the operator's leg. Trousers should be slightly baggy, so that there is give and not the chain pulling the leg into the chainsaw, but instead pulling excess stopping fabric into the chain mechanism. After stopping a saw, the trousers are scrapped, and the saw must be field-stripped to remove the fibres and allow it to run again.If trousers are washed the material inside may degrade over time. As a result trousers should be replaced, and not washed in hot water too frequently. Likewise trousers should be free of rips and tears that may catch on a chain saw or timber when moving through a forest.Chainsaw protective trousers in the EU must comply with EN381-5.[1]

Jacket

Chainsaw protective jackets in the EU must comply with EN381-11.[1]For detailed information on fabric ratings, see the section above on trousers. The logic is much the same - the protective materials are designed to slow the chain's rate of cutting and clog the mechanism, rather than protect the wearer completely.

Gloves

Chainsaw gloves.Note that only the back of the left hand glove contains chainsaw protective fabric, and so only that glove carries the chainsaw label.Chainsaw gloves have cut-proof fabric protection like that for trousers, but only on the back of the left hand. It's especially important that work gloves are flexible, which limits how much padding they can have. Experience has shown that most chainsaw injuries to the hands occur on the back of the left hand.In the EU, chainsaw gloves must comply with EN381-7.[1][2]

Boots

Chainsaw boots are based on ordinary steel-toe boots, but have layers of chainsaw protective fabric on the exposed front surfaces. They are available in lace-upleather or rubber wellington boot versions. Popular manufacturers of chainsaw boots sold in Europe include Haix, Klima-Air, Meindel and Oregon.In the EU, chainsaw boots must comply with EN345-2.[citation needed] These boots must be to the appropriate EN20345 standard for general safety footwear[2] and must also be distinctively marked as suitable for chainsaw use, according to EN381-3[1]Protective chainsaw gaiters to EN381-9 over general steel-toe boots are acceptable for occasional users.[1]
