Safe Operation

1. General requirements for labor protection

General labor protection requirements are set out in the instructions "General requirements for labor protection for workers engaged in logging and forestry work".

2. Safety requirements before starting work

2.1. The foreman (link) should clarify with the foreman the specifics of cutting (trimming) branches at a given cutting site, dangerous zones and other safety requirements specified in the technological map for felling, which the team gets acquainted with before starting work.

2.2. Do not arbitrarily change the established order of work without the permission of the master.

2.3. Check the completeness and serviceability, put on special clothing, safety shoes and safety devices and constantly use them in work.

2.4. Check the serviceability of the equipment: the ax is mounted and wedged, the blade is sharpened (the angle of the nozzle is 84 degrees, the ax handle is made of dry hardwood, without hooks and burrs), the saw (lopper) is in a tucked state, with a directed saw chain, with working safety equipment.

2.5. When starting a petrol lopper (chainsaw), you must: remove unauthorized persons from it at a distance of at least 1,5 m; Place the chain saw on a solid object and place the chainsaw on a flat surface so that the teeth of the chain do not touch surrounding objects; take a stable body position, with a sharp jerk of the starter, start the engine; warm up the engine at low speeds; Test sawing to ensure proper sharpening of the saw chain and proper operation of the tool.

If faults are discovered during inspection and trial cutting and it is impossible to eliminate them on your own, you must report them to a foreman or mechanic. It is not allowed to use a faulty tool.

3. Safety requirements during work

3.1. When starting work, the limber must inspect the workplace and, if necessary, clear the paths to approach the trees, as well as outline the sequence of techniques for felling (trimming), collecting and burning branches.

3.2. The branches of trees lying along a slope of 20 degrees or more and across a slope of 15 degrees or more are cut off and the trees are secured. The chopper is located on the upland side.

3.3. When cutting branches, the chopper must take a stable position and be on the opposite side of the tree from the tree being cut.

It is necessary to cut off (trim) branches in the direction from the butt to the top of the tree.

3.4. It is not allowed to come closer than 5 m to a worker cutting (trimming) branches.

3.5. When cutting branches with a gasoline-powered lopper, it is necessary to place the emphasis close to the branch, and then insert the sawing apparatus into the wood with light pressure. The stop of the petrol lopper must protect the worker’s foot in any position.

3.6. It is necessary to move the cutting part onto the branch smoothly, without jerking or hitting, to avoid the sawing apparatus from rebounding.

When trimming branches, observe the rule of sliding and supporting the saw on the trunk. For a stable position, place the feet at a distance of 30-40 cm from each other and 10-12 cm from the trunk when trimming the upper and side branches. Do not change the position of your feet until the end of the work cycle unless the guide bar is on the opposite side of the trunk and the saw body is not resting on the tree trunk.

3.7. When clamping the sawing apparatus in a cut, it is necessary to turn off the engine and then release the sawing apparatus.

3.8. When moving from one tree to another, the engine of a lopper (chainsaw) that is not equipped with a brake must be turned off, and one equipped with a brake must be on.

3.9. The cutter (cutter) of branches is not allowed:

violate the 50-meter dangerous zone of felling;
cut off (cut) the branches on which the tree rests, without taking the necessary measures to prevent the trunk from settling;
chop off (cut) branches from an unstable lying tree;
chop (cut) branches from trees lying in heaps or on the tractor shield;
stand on a tree trunk and its branches when cutting (cutting) branches;
knock down dry branches with the butt of an ax;
place your feet on both sides of the trunk ("saddle" the tree being cut);
transfer control of the lopper (chainsaw) to someone else during the shift;
work with a petrol lopper (chainsaw) with a dull saw chain;
carry out repairs and refuel with the engine running;
cool the chainsaw (lopper) engine with water or snow;
use your body weight to apply additional pressure on the saw (petrol lopper);
place your foot under the sagging parts of the trunk, trim (chop off) branches with a power tool in the dark.

3.10. When cutting thick branches with a gas-powered saw (lopper), you must:

sawing off after bringing the saw stop to the branch;
cut off tense branches in two steps (first trim the tense fibers, and then cut the branches flush with the trunk);
Long branches, in order to avoid pinching the sawing apparatus, should be sawed off at a distance of 1,0 - 1,5 m from the base, and then flush with the trunk.

3.11. Chopped branches must be removed as they accumulate, while being careful to avoid injury to the face or bruises during transitions.

3.12. It is not allowed to hold the ax in your hands or in your belt when carrying branches, or toss it over to transfer it to another worker.

3.13. It is necessary to carry branches with mittens and small loads so that you can clearly see the road in front of you.

3.14. When burning branches, care must be taken to ensure that sparks do not fall on clothing.

3.15. When clear-cutting, when the collection of branches at the cutting site after the end of the forest hauling is carried out using a mechanized method, it is necessary:

before starting work, cross the deadwood into segments 3-4 m long;
collect branches with a picker no closer than 25 m from the forest wall, seed clumps and individual trees;
lumberjacks preparing the cutting area for the pick-up operation should be no closer than 30 m from the pick-up work site.

3.16. Pruning (trimming) of branches on windfall trees should be done after sawing off the butt block.

4. Safety requirements in emergency situations

4.1. The victim or eyewitness must notify the foreman or the relevant work manager about each accident, and after providing pre-medical care, if necessary, take the victim to a medical facility. If possible, preserve the situation of the incident.

4.2. Work stops during heavy rain, thunderstorms, heavy snowfall and thick fog (visibility less than 50 m), radiation, chemical, other dangers, and during an emergency warning.

4.3. During a thunderstorm, work stops, metal objects and mechanisms are placed away from people, and people, if possible, should take shelter indoors or take a safe place in a clearing, in small folds of terrain on a hillside, between trees growing at a distance of 20-25 m from each other.

During a thunderstorm, it is prohibited to hide under trees, lean against their trunks, be near or under power lines, come closer than 10 m to separate trees, poles, towers, lightning rods, tall stones, etc., be at the top of a hill, or closer 10 m from machines and mechanisms.

4.4. If a fire is detected, begin extinguishing it using available means, maintaining safety. Report the fire to the foreman, forestry department, forestry department, and if there is a threat to life, leave the danger zone. If necessary, call the fire department.

5. Safety requirements at the end of work

5.1. Clean the tool from sawdust and dirt, place it in storage.

5.2. Remove personal protective equipment and store it.

5.3. Carry out hygiene procedures, inspect to make sure there are no ticks, and if present, remove.

5.4. Extinguish the fires, sprinkle them with soil.

5.5. Report all comments to the foreman and record them in the log of administrative and public control on labor protection.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
