periodically and when changing the working place, the permanent verification of well-condition

and working state of the tools, devices and equipment.

By working at height it is understand the activity performed at minimum 2 m measured

from workers foot until the reference natural base (the ground level) or any other artificial base

from which the risk of falling exist.

For the works execution at height some things have to taken into consideration:

- the preliminary technological organization of the works at height by the collective

insurance of all working conditions during the entire period of works development;

- the endowment with individual protection equipment according to the conditions

from the working place so that the safety of executor to be insured;

- the compulsory initiation, training and usage of collective and individual

endowments corresponding to the working place and respective works risks;

Working at height is allowed only if the working place was improved and endowed from

technical and organizational point of view. The access to and from the working place placed at

height must be insured against falling of the workers,

The workers must use the constructors and assembler safety belt, according to the present

norms. The anchorage point must be chosen so that the fixing zone of the worker to be under the

level of the anchorage place during the whole period of work. The safety belt must be checked

before using it. For working at height it is compulsory the usage ofcrash helmet. Before starting

the works, the worker has to check the integrity of the helmet, of the damping system and of the

fixing belts.

The works have to be developed only under surveillance; the person nominated for

surveillance must check before starting the work if the all the necessary safety measures were

insured.

The inclined beams, plans and platforms used in materials handling must be resistant and

provided with safe catching and fixing devices, any displacement during the works being

forbidden. They will have a slope of maximum 20% and a width of minimum 1 m. They will be


4/8



provided with high balusters of 1 m with intermediate bonds and with lateral borders of 10-15

cm.

The ascension ramps will have a slope of maximum 1:3 and at every 30-40 cm some

wood laths will be fixed on the whole width of the ramp. It is forbidden the blockage of the

access ramp with building materials or any other objects. The ramps must be permanently

maintained and cleaned.

For using the scaffoldings, formworks and centrings there will be applied the previsions

from the Specific Labor Security Norms for formwork, centrings and scaffoldings works.

The quality of the wood materials must correspond to the project. The floorings made of

steel are made from expanded or ribbed steel sheeting. The joints between the panels or the

bordages of the floorings have maximum 10 cm width. On the floorings surface in the slope or in

the curved part some wood laths will be fixed at a distance of 30-40 cm, against sliding.

The fixing the flooring on the supports will be made such that the possibility of

displacement or sliding to be excluded. The floorings will not be placed on cantilevers.

The usage of installations, devices and tools for working at height is allowed only if the

working instructions and the labor security are adapted to the site conditions. At the working

place at height there must be lifted only materials which are absolutely necessary.

The necessary tools for execution of different operations must be kept in special pockets

or in sheaths fixed on the safety belt. The tools and the materials must be lifted gradually,

according to the necessity, with a helping rope, being forbidden their throwing from the ground

level to the working position or vice versa.

At the elaboration of the site organization project, there must be envisaged a series of

measures which would insure the labor safety:

- the enclosure of the site with definitive or inventory elements;

- the leveling of the ground before starting the works;


5/8



- the enclosure of the dangerous areas on the site (places where montage works are

executed, the action radius of the cranes, the place where the scaffoldings are dismounted, the

slaking pits etc.);

- the trenches or the channels with a depth larger than 1 m will be provided with

walkways for passengers having the minimum width of 0.7 m and with balustrades (on both

sides) of 1 m height and wood boards of 15-18 cm;

- the enclosure of the holes, shafts, deep trenches, of the holes from the floors etc.;

- the insurance of rainwater removal through drainage trenches.

Measures taken for the labor security at the concreting works

- the operations of charging/discharging the materials and the equipment used for

concreting works will be made only in the places mentioned in the site organization or in the

special authorized or established polygons;

- the access of the workers under the concrete mixing bucket is forbidden when it is

lifted;

- the cleaning, the maintaining and the repair of the concrete mixing are allowed

only after the machine has stopped and has been disconnected from the power;

- the transport of concrete on the scaffoldings will be made on floorings of

minimum 1.2 m width, with balusters and borders on the edges; the wholes from the floorings

through which the concrete is poured must be covered when concrete pouring works are not

performed;

- when the concrete is transported on the vertical direction it is forbidden the

stopping of the workers under and in incidence of the lifting device;

- when discharging the concrete it is forbidden the workers ascension on the

distance of 10 m from this place, and in the front of the evacuation hole is mounted an inclined

shield;

- in case of the concrete pouring from a height greater than 1.5 m, the working

floorings must be enclosed with balusters and wood boards on the edges;

- when poring concrete on surfaces with a slope greater than 300 the concreters

must wear safety belts tied through ropes by the resisting elements of the construction;

- in case of pouring concrete with concrete buggy there will followed the

instructions for the use of these devices; before work starting, the technical condition of the

concrete buggies and the devices and accessories, including the hanging device will be checked;

- it is forbidden for the workers to stay under the concrete bucket;

- in case of the blockage of the concrete buggy, this will be cleaned only when it is
