HEALTH AND SAFETY AT WORK WHEN CARING FOR TREES

HEALTH AND SAFETY AT WORK WHEN CARING FOR TREES

Carrying out work on the care of trees, and mainly within the crown, and in felling and grubbing trees is associated with a serious risk. People who carry out these works are most at risk, but also bystanders and the environment are endangered. This danger arises from the following conditions and circumstances:

1) use of mechanical equipment, sharp tools and ladders etc.:

2) work at great heights, often in very uncomfortable positions;

3) work in the vicinity of electric and telecommunication wires as well as live cables;

4) weakening of tree trunks and branches, often hard to say;

5) using chemicals to disinfect and protect trees;

6) possible collision with vehicles, various devices in the vicinity and with passers-by;

7) possible collisions with various underground devices (utilities).

The existence of so many causes of danger during maintenance work forces to consciously anticipate the potential danger. Therefore, strict compliance with the rules of occupational safety when performing these activities is very important.

If the work is carried out by special brigades, the principles of training and compliance with health and safety rules are set out in the Act on Health and Safety at Work of 30 Mark 1965 r., Resolution of the Presidium of the Government no 592 of 1 of August 1953 r., and the Regulation of the Ministers of Labor and Social Welfare, Forestry and Health of. 26 February 1953 r. on health and safety at work of workers engaged in logging, carp and resin (Dz. U. no 20 item. 78). Tree removal, branches and shrubs under the low and high voltage lines is allowed only in the presence of an authorized person in accordance with the Regulation of the Minister of Mining and Energy of. 20 April 1960 r. (M.P. no 38).

The Department of Zadrzewień and Greenery of the Nature Conservation League in Warsaw has since 1969 r. own regulations "on work safety in felling, clearing and caring for trees ", used in subordinate brigades of employees. These regulations regulate the rules for the use of equipment, machines and tools and define the scope of the required training authorizing to perform various works. Special qualifications are required for operators of hoists and chainsaws.

Carrying out maintenance work on trees in the vicinity of electric lines, telephone lines and buildings, and over the carriageways of streets and roads, requires agreement with the appropriate users or the supervisory service. In all cases of potential hazard, workplaces should be properly secured and marked by barriers, putting on the ropes, placing warning boards, etc.. The basic principles of occupational health and safety when tending trees are as follows:

1) Workers working at high altitudes should be fully physically fit and not show "fear of heights", which must be confirmed by appropriate medical examinations.

The age of these workers should not exceed 30 years.

2) During work, meteorological conditions must be taken into account, and therefore the slippery of the rungs of the ladders, branch, swinging trees and ladders in high winds etc..

3) Be sure to check before climbing a tree, whether there is a risk of limbs or branches breaking off easily as a result of decay and rotting of their interior. This is especially true in older trees with soft and brittle wood, such as poplars, clones etc.. In case of stump tree infection by chuba, the presence of fruiting bodies of this mushroom may be an indicator of danger:

4) The area around the tree should be tidy and cleared for easy access.

5) Work is best done in groups or at least through 2 persons, which enables mutual assistance and security.

6) Work tools should be very strong.
