Helmet Clothing

Clothing

A helmet which integrates visor and ear defenders into one unit, a very popular arrangement with chainsaw users.

Helmet

The helmet offers some protection for the user’s head against impact by the cutter bar of the chainsaw should a ‘kickback’ occur. Kickback is when the running chainsaw jumps up unexpectedly out of the cut, thus endangering the saw operator. Helmet protection can only be successful if the chain brake has been operated to stop the saw chain, since a chain running at full speed can easily cut into the helmet. The helmet, and its eye protection guard, also protect against impacts from small falling or flying objects, such as dead twigs and branches from a tree being felled.[3]

Exposure to the sun causes the plastic of the helmet to weaken over time, so it is recommended that a helmet is replaced every 3–5 years. A helmet normally has a symbol inside that shows when it was made. Many helmets also now have a sticker on the outside that fades with exposure to light. When the sticker has faded the helmet should be replaced. Another way of determining if a helmet needs to be changed is to press the two sides of the helmet towards each other. If a cracking noise is heard, the helmet must be replaced.

In the EU, a helmet must meet the requirements of EN397.[1] Helmets as well as other safety equipment in Germany must have the KWF sign.

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.

In the EU, a visor must comply with EN1731, or glasses must comply with EN166.[1]

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 more easily engaged. The safety mitt also protects the operator’s left hand in the same way as chainsaw safety gloves. The protection on the left hand mitt protects when the chain derails and jumps over the front handle.

Most safety mitts have a protection class 0 (up to 16 m/s chain speed, see below). There are mitts available covering class 1 (20 m/s chain speed).

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 the recommended exposure limit of 85 dB from the National Institute for Occupational Safety and Health.[4]

In the EU, ear defenders must comply with EN352-1.[1]

Trousers

Special fabrics have been developed for chainsaw clothing, and this development is still ongoing. Conventional fabric is useless as protection against a running chainsaw, as the fabric is cut through immediately.

There is a real struggle and conflict 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 unable to move easily and/or suffering from being too hot is not safe. Extra fabric layers are 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. Additionally saw and chain technology seems to be outstripping fabric technology. It is almost impossible to protect against high power saws employing aggressive cutting chains.

A classification scheme has been developed in the EU to rate trousers, and fabric in general, for protection against cutting.

Safety guidelines

Safety guidelines for felling trees with chainsaws

Chainsaw felling of trees is recognized as one of the more dangerous activities in forestry. However the risks can be reduced considerably with well trained and professional operators. WorkSafeBC and the BC Forest Safety Council have produced a training standard that will go some way in achieving these risk reductions. The document begins by providing an initial safety meeting checklist and universal principles for safe felling. The standard then proceeds to discuss various safety aspects under the following headings:

  • Working safely: This considers general safety aspects such as safety programmes.
  • Clothing and personal equipment: The various safety clothing that should be worn is covered.
  • Safety equipment and personal wellbeing: This section includes information on aspects such as operator visibility and climatic factors.
  • Stretches: Various exercises that should be performed by operators are described.
  • Chainsaw and other equipment: This includes choosing a chainsaw, carrying a chainsaw by hand and chainsaw refuelling.
  • Chainsaw maintenance and filing: A chainsaw maintenance checklist is provided, along with safe chain filing information.
  • Safe chainsaw handling procedures: Various safety aspects are covered, with a focus on kickbacks.
  • Axes and wedges: The uses of axes and wedges with chainsaw felling are described.
  • Planning and safety meetings: Various plans, meetings, checks and procedures are discussed.
  • Falling areas and active falling areas: The safe working procedures are described for entering a falling area and barricading a falling area.
  • Crew transport and first aid coverage: Transportation of the crew, tools, fuel and equipment is discussed.
  • Tree species group hazards: The risks associated with felling various tree species is described.
  • Dangerous tree indicators: The aspects of a tree that create safety hazards are explained.
  • Various cutting procedures: These include different types of undercuts, directional control and wedging.

Other aspects covered include managing risk factors, escape routes, opening the falling face, site-tree assessments, inadequate felling cuts, correcting incomplete felling cuts, and steep slope, upslope and riparian felling.

Property Management

Whether you need to cleanup from a big storm or want to prepare your trees to better withstand the next one, tree felling harare are the experts to call. Storm-damaged trees typically react by producing numerous, weakly-attached branches. If these branches overhang your home or other buildings, they pose a serious risk of failure in the event of additional storms. They are far more prone to fail again than original-growth branches. We can selectively remove or reduce these branches to enhance the appearance of the tree, to improve your safety with respect to potential branch failure when the next storm hits.

Pruning can serve two purposes, hazard reduction and maintenance. For hazard reduction, pruning removes branches that might compromise the structural integrity of the tree. For maintenance, pruning can make your tree more aesthetically pleasing aiding an injured tree in the healing process. We offer both services in order to keep your trees looking healthy while looking attractive.

Stumps can be an unsightly, enduring blemish on an otherwise stately landscape. Let us help you quickly and easily restore your property to its full beauty.

Mini Four

Mini Four

Quelle que soit l’utilisation que vous allez faire du mini four electrique que vous voulez acquérir, il y a quelques critères qu’il ne faut pas oublier lorsque vous allez faire votre choix. Un de ces critères est sa capacité. Il en existe certains qui ont une capacité inférieure à 20 litres mais aussi d’autres qui en ont une supérieure à 50 litres et qui sont tout de même considérés comme mini four. Pour savoir qu’elle taille il vous faut, vous devez d’abord réfléchir à l’utilisation que vous allez en avoir. Si vous faites cet achat car vous emménagez seul dans un petit studio, vous n’avez peut-être pas besoin d’une grande capacité d’une part parce que vous aurez peu de place et d’autres part parce que l’on ne cuisine pas en même quantité pour une personne que pour quatre ou cinq. Ne vous inquiétez pas en ce qui concerne la vaisselle adaptée, on en trouve maintenant partout que ce soit du plat simple au plat à tarte et ceux quelque soit la taille de votre four. Au contraire par contre, si vous souhaitez investir dans ce type d’appareil parce qu’un four traditionnel ne suffit pas pour faire la cuisine lors des grands repas entre amis ou en famille, il est peut-être préférable d’en choisir un avec une capacité plus importante.

Les autres critères importants dans le choix de votre produit sont les différentes options et fonctionnalités qu’il offre. Celle qui semble la plus nécessaire pour faire cuire vos plats et desserts de façon homogène et sans avoir à trop vous soucier de la cuisson est la chaleur tournante. Avoir un mini four chaleur tournante c’est l’assurance d’avoir encore plus envie de cuisiner et de vous préparer de bons petits plats. Bien entendu, ce n’est pas la seule option qui vous rendra agréable l’action de cuisiner. Regardez aussi le nombre de modes de cuisson que possède le ou les appareils qui vous intéressent. Le mode décongélation par exemple peut s’avérer utile dans bien des cas. Et l’option grill est agréable quand arrive l’été, la chaleur et l’envie de manger des grillades entre amis. Il y a aussi une chose à laquelle nous ne pensons pas toujours et que nous regrettons quand notre achat ne la possède pas, c’est la minuterie. Elle peut paraitre accessoire mais c’est là encore un outil qui vous rendra l’action de cuisiner plus agréable : vous n’aurez pas à vous préoccuper constamment de l’heure et n’aurez qu’à surveiller de temps en temps la cuisson de votre plat.

Finalement, après avoir fait une sélection selon tous ces critères important, c’est surtout l’esthétique du produit et les moyens que vous possédez qui détermineront votre achat. Sachez que dans ces deux domaines les choses sont assez variées. De la porte décorée à celle teinte en noir pour un aspect plus design et actuel en passant par la porte classique, transparente qui vous permet de voir l’état de la cuisson sans ouvrir la porte du four vous trouverez un large choix de mini four pas cher. De même en ce qui concerne les prix de ces derniers : ils peuvent varier entre 40€ environ et plus de 900€. Tout dépend donc de vos goûts et de vos moyens.
