* NOTE:

The observation area of the research (ASL RMB) represents about one fifth in terms of population and activity in the construction sector – residential construction - in Rome Province.

There follow the INAIL data for Rome Province on accidents in the construction sector subdivided by group of material agent, form of event and the INAIL codes. This subdivision allows for an approximate analysis of the phenomenon.

The high percentage of small firms and irregular employment in this sector probably involves an underestimation of minor accidents.

With regard to occupational diseases, there is probably an underestimation of both the unlisted pathologies (e.g. osteoarticular pathologies and those from repetitive movements) and a lack of observation due to poor compliance with health monitoring requirements. The extent to which the arrival of relatively young non-EC immigrants for short periods changes the potential harm rate should also be assessed.

ACCIDENTS

 

Laying of power cables

In 10% of cases, the passage of open-air or underground power cables does not guarantee protection from risks due to abrasion, wear and mechanical damage. 

Falling from ladders

In order to passages or overhead connections,  simple ladders are used without anchoring or without being held at the foot (80% of cases).

Accidental contacts

In older generation generators there is a 50% of contact with high temperature parts (muffler and exhaust pipe) since they are not insulated.

 

 

HEALTH & ENVIRONMENT

 

Physical;

 

Noise: workers may have Lep,d between 80 and 85 dB(A) if they work mainly near electric generators.

Chapter 1 - DESCRIPTION OF STAGE

 

Tracing excavation areas on ground; definition of operation site of excavator with suitable fencing, PVC netting  or two-coloured tape.

The machinery for excavation and for making the foundation piles shall be transported on trailers pulled by lorries.

In civil engineering works requiring a basement, excavation shall be greater than 2 mt.; an access ramp must therefore be made to enable vehicles to reach the bottom.

For the carpentry work, metal and wood elements shall be unloaded. In the case of foundation piles, metal formwork prepared off the building site may be used. 

Foundation piles are often prepared for connection with the subsequent structures using a concrete breaker.

Once the piles are made, they are connected horizontally by the excavation of trenches for laying the formwork and the reinforcement of the beams; the reinforcement plates are dowsed with stripping oil.

Once the form is prepared, the structure is laid using concrete prepared by the cement mixer; the concrete is conveyed directly into the formwork.

When a cement mixer cannot be used directly, the concrete is poured from skips carried by the crane or by means of a pump.

The workers in this operation must correctly guide the laying as well as all the subsequent vibrating operations.

Once the concrete is consolidated, the formwork is removed using manual tools (burton).

Chapter 3 - RISK FACTORS

 

ACCIDENTS

Pile construction

Falling into openings for piles

In 80% of building sites boring of foundation piles takes place without the holes being provided with protection to prevent falling by workers collaborating on the ground with the pile machine operator.

In 50% the newly made holes are left without protection.

In 60%  these holes are covered in an unsuitable way (for the material used and execution procedures)

Protection of head

In 40% of cases the pile worker on the ground does not use the protective helmet although provided.

In 50% of cases during the stripping operation protective helmets are not used.

In 50% of cases gloves are not used for handing materials.

Falling or tripping

In nearly all the cases, once the foundation pile is completed, there is no elimination of the risk of tripping or falling over protruding rods. 

Roads

In 90% of cases there is no definition with barriers of the “field of action” of excavation equipment.

In 90% of cases the railings on the access ramp to the work area are not suitably built or maintained (use of plastic netting, excessive distance between posts, boards for transit in poor condition). 

 

 

HEALTH & ENVIRONMENT

 

Physical agents;

 

Noise: workers in this phase may have Lep,d between 80 and 85, and 85 and 90 dB(A).

 

In this phase exposure to noise by workers is affected by the use of the following equipment : circular saw, excavator or mechanical shovel, cement unloading with cement trucks, use of crane trucks and mobile boring equipment, nailing of boards.

Information

In 90% of cases the pile machine operator and supporting worker on the ground work in a small area without having been informed of proper safety procedures (reference is almost always made to the signs on the machinery warning people to stay outside of the range of operation of the machine).

 

Co-ordination between simultaneous working stages

The simultaneous execution of work of excavation, pile boring and earth shifting takes place with poor definition of the fields of action and without any procedures for co-ordination between this work.

In all cases the carpentry stripping operations take place without any specified procedure and in 90% of cases without any supervision.

Chapter 1- DESCRIPTION OF STAGE

 

Assembly of crane (fixed or running on tracks).

An excavation proportional to the base of the fixed crane is made; four reinforced concrete supports (pillars) are made in this excavation; the metallic supports protruding from these pillars are used to anchor the plates and base frame of the crane.

In case of cranes on tracks a flat concrete area is made and the crane tracks are laid.

The parts of the crane with the help of a crane truck; the base plates of the crane tower are placed and secured to large bolts protruding from the base.

The bogie is then placed on the tracks. 

The crane tower consists of metal sections previously assembled on the ground using a bolting system.

Each element has a length of between 3-6 metres.

The methodology set forth by the manufacturer must be used for all cranes. 

Tower crane

The crane jib and the camber may be installed as a single piece prepared on the ground or according to the following phases:

a) cusp with centre plate fixed to the body of the tower;

b) camber, without counterweights, attached to the cusp;

c) hook attached to the cusp;

d) counterweights of camber;

Finally, the steel cable is installed, running through the pulley of the motors and the conveyor device of the jib.

Assembly is started on the ground of the parts of the crane to be subsequently lifted and bolted at the proper points; during this work stage, if service cranes with passenger platforms are not used, the specialised workers would risk falling when going to their workplace; they must therefore use safety harnesses with a double safety cable. The double cable is necessary because the running rings of the safety cable (horizontal structure) or the intersections of the grid structure (vertical) of the crane must be bypassed; the cable must therefore be designed for unhooking and subsequently re-hooking.

Self-supported cranes

There are two types of self-supporting cranes: telescopic and articulated.

The telescopic crane consists of previously assembled metallic elements (with cable and motors already electrically connected since the crane motor itself is used to assemble the crane) running along the vertical axis. 

Articulated cranes

The articulated crane is positioned along the base bogie, and the blocking pins of the various elements forming the jib and tower. The latter are  lifted using their own motors, opening up until the crane is fully extended and lifted.

The crane is taken down using its own motors, replacing the pins without the help of extra equipment.

Installation of rod-bending and steel-cutting machinery, crusher , circular saw

A truck is used to transport the rod-bending and steel-cutting machinery, crusher and mixer (the latter two machines may also be brought to the construction site subsequently)  at pre-set points). After unloading by means of the crane and harness, they are connected with the power supply.

With regard to the circular saw, it is generally simply unloaded since it hardly ever just has a single location, but is shifted according to the workplaces of the carpenters.

 

Cement mixing plant

In some building sites (5%) a central cement mixing site is prepared to mix the concrete.

An area of ground  is marked off for positioning the tank containing the powdered cement; this is transported with a lorry and is lifted with the truck crane and positioned on the bases already made, and is finally secured.

The procedures described above are used to unload the cement mixer machine, securing it to prevent it from falling over. The machines for adding inert material (conveyor lift) is connected to the mixer mouth and suitably set for collecting and  moving the material, with  a continuous chain of scoops.

Chapter 1 – DESCRIPTION OF STAGE

 

After the dismantling work for walls in contact with the ground, they are then waterproofed. 

The waterproofing of walls to be buried is undertaken by coating them with bituminous material that prevents damp from penetrating.

This material may be spread with a brush and/or a roller in order to fill the small spaces on the surface to be insulated.

For more effective waterproofing, a bituminous layer is laid after applying a bituminous adhesive (primer) with the help of the heat produced by the combustion of GPL with a suitable burner. The edges of the next layers and the outer edges are melted, and pressed together with a tool (trowel) so that they are joined when the material cools.

In some cases the bituminous coating is protected by covering it with “non-fabric fabric” or sheets of plastic material stamped in relief in such a way that when two sheets overlap the edges connect together.

The handling of the roles of coating on pallets is undertaken with the help of lifting devices; the worker takes one role at a time, placing it on a flat surface for the necessary cutting. 

Once waterproofing is completed, earth moving equipment is used to fill the spaces between the wall and the ground.

 

 

WORKERS

 

2/3  operators skilled in waterproofing.

A crane operator crane for handling material (roles on pallets, tar barrels, gas tanks).

Mechanical shovel operator.

 

 

Chapter 2 - EQUIPMENT AND MACHINES

 

Crane or mobile crane, cables and harnesses for loading - unloading of roles of coating.

Tanks of liquid gas, rubber coated tubes with UNI-CIG standards, flame nozzles; infrequently, a support system for the nozzle is used; cutter, ruler, trowels and metal spatulas.

Platforms on trestles or equivalent per heights less than mt. 2; alternatively, metal scaffolding is used. 

Mechanical shovel for refilling.

 

Chapter 3 RISK FACTORS

 

ACCIDENTS

 

- (90%) Gas tubes for which it is impossible to determine the expiry.  

- (40%) Wear on connection points between tubes and metal covering. 

- (90/%) Danger of falling due to coating for overhead areas (ceilings of garages, basements etc.)  because of the absence of guardrails (even when these areas have a height over mt. 2) since the railing posts must be removed to enable the coating to get by.

- (30%) Risk of falling from working areas onto trestles when the floor boards are incomplete.

- (90%) Lifting and transport of roles of coating undertaken with simple systems (forklifts) without suitably securing the load.

- (40%) Lack of shoring for the earth opposite the walls to be insulated. 

- (100%) Danger of falling from the excavation edges and of coming into contact with excavation equipment during the refill phase, since the protective barriers are promptly eliminated for the operation of the mechanical shovel, without the latter’s range of action being defined.

RESULTS

It was not possible to determine the volatile fraction for all the values observed in the installation of coating.

 

METHODOLOGY

Sampling. Samples were taken with the Zambelli Mod. 2 LE personal sampling device for low flows, aerosol absorption on PTFE filters porosity 2 mm according to the NIOSH 5515 method. For the volatile fraction of the APH,  I.P. Zambelli Mod. TK 200 passive sampling devices were used..

Analyses. The analyses were conducted with gas chromatography with a mass detector; the accuracy of the method is 0.3 mg.

Sample timing:

Personal sampling: sampling lasted 120¸180 minutes with a constant flow of 2 l/min. for a sample volume of 240¸360 litres.

Passive sampling: sampling lasted 120¸180 minutes.

 

Total failure to use protection systems for the respiratory tract at the time of applying the primers (solvents) and melting of the coating.

 

 

COMBINED OR ORGANISATIONAL

 

 - (100%) The activity takes place at the same time as others without any planning or co-ordination between the various job activities. A high percentage (90%) of building sites coming under D. Lgs 494/1996 have shown that the Safety Co-ordinators have not managed to implement the co-ordination of overlapping working stages.

 

- (80%) The basic lack of assessment and information on the manual handling of loads.

 

- (80-90%) Poor knowledge of the characteristics of the substances used (technical sheets) and the corresponding behaviour for health standards.

 

- (90%) The workers in the coating process do not know about the noise level to which they are exposed.

Chapter 1 -  DESCRIPTION OF STAGE

 

Once the beam or plinth foundation is completed, the supporting reinforced concrete structure of the building is started (pillars, beams and slabs).

Extensions are attached to the steel reinforcement protruding from the foundations until they reach the height of the first slab, and the formwork for casting the pillars is prepared.

In some cases cardboard casing (cylindrical pillars) or steel casing (for large size continuous walls) is used.

A worker will direct the flow of concrete into the form and undertake the vibration of the concrete, sometime before the casting is complete.

When casting the pillars a ladder or scaffolding is used to reach la height of the slabs (about mt. 3).

The casting is undertaken with a pump or a conveyor.

The subsequent stage is the construction of the horizontal formwork and casting of the beams to connect the pillars.

In this case, the formwork is braced by wood or steel supports.

Once the pillars and beams are completed, work is started on the floor slab, lift-well and stairwell.

In order to build the slab, a wooden deck is built, braced by steel supports, on which the reinforcement rods, and hollow gauged bricks are laid before casting the concrete.

In case of the use of prefabricated cement material (predalles), after an electrowelded metal reinforcement grid is laid, the concrete is poured directly on the structure.

The lift-well is built by casting the concrete into the form containing the reinforcement rods.

For the stairs, the corresponding reinforcement is prepared before casting, using wooden nailed boards containing the metal reinforcement and the necessary concrete.

The material necessary is handled with lifting devices.

Chapter 1 - DESCRIPTION OF STAGE

 

The erection of metallic scaffolding closely follows the building during construction.

Installation may take place with prefabricated metal frames or with pipes and metal joints.

During the construction of the first slab, the erection of scaffolding on the perimeter of the building is started.

Erection of scaffolding

The base of the scaffolding is prepared on solid ground that is as level as possible.

The metallic structures composing the scaffolding, fitted with support disks, are placed on the ground; connections are made in such a way to set up the upright pieces for the first level at a height of about mt. 2. Afterwards, using the first level vertical  pieces consisting of pipes or prefabricated frames, the supports for the second level are prepared. Once the upper part of the scaffolding level is completed, the cables are arranged for the connection of the safety cables to the workers’ belts. With the belt attached to the cable, work is continued on the scaffolding with the installation of the guardrails and diagonal pieces. 

This operation continues up to the required height, with the scaffolding being secured to the building under construction in the required way, with the gangways as close as possible (in any case less than 20 cm).

The installation of scaffolding is usually undertaken by two experts in this operation. While the prefabricated frames fitted together are secured against coming apart by pivot pins, the pipes are secured with corner joints inn which the bolts are tightened with precision spanners in order to ensure homogeneous and correct tightening:

In the installation of scaffolding, the instructions in the booklet provided by the manufacturer must be explicitly followed; the manufacturer shall likewise provide certification as the standards of the product.

Layouts other than the standard one require calculation, verification and a specific design.

The dismantling of scaffolding is undertaken by undertaking the assembly operations in inverse order, taking into account that the dismantled material must not be thrown down from above but rather lowered to the ground with lifting devices (tackle block, crane, windlass) in order to avoid any damage to material that (sometimes not visible to the naked eye) could endanger the stability of the assembled scaffolding.

In 40-50% of cases the workers have not received adequate training on the use of individual protection devices  (length and securing point of the safety cable, points and applicability of the hooks for safety cables, hardly ever conformed by static calculations). 

In 10% of cases the workers are not familiar enough with work safety procedures. 

The persons in charge are not sufficiently well trained  (convinced) of the role they undertake in supervising the workers. 

Manual handling of scaffolding elements including the heaviest ones (uprights) takes place without adequate information.

Chapter 1 - DESCRIPTION OF STAGE

 

This work stage takes place at the same time as work for the assembly of the metallic scaffolding which provides protection against the danger of following outwards for the workers building the slab. 

Vertical structures

Starting from the rods left protruding from the pillars, reinforcement of the pillars is continued up to the slab above.

The carpenters use wood panelling (positioned on the vertical reinforcement and nailed) to make the form of pillar in order to allow the concrete to be poured.

Pressed cardboard formwork is generally used for cylindrical pillars. 

Formwork using wood or metallic elements may be used to make large structures or continuous walls and to make the walls in lift-wells.

Once the form is completed the concrete is poured using the pump or skip transported by the crane; a worker directs the flow into the form as well as vibrating the concrete in order to ensure that the flow is homogeneous.

Horizontal structures

Beams

Once the vertical supporting structures, the horizontal connecting elements (beams) are built; the construction of the horizontal form is similar to that for the vertical one, taking into account, however, that the horizontal form requires the setting up of a support also when the concrete is poured. 

Slab

For the construction of the slab, the vertical supports are positioned and then the decks for covering the area of the slab are laid.

The material required for building the slab is placed on this structure: steel elements, supporting joists and hollow gauged bricks.

In some cases prefabricated elements (platforms) are used, consisting of the slab floor with supporting joists hollow gauged polystyrene bricks, on which an electrowelded metallic net is placed.

The  material is placed on the working surface with the help of lifting devices or the crane.

Stripping of reinforcement

The stripping operations are conducted  at regular intervals related to the consolidation time of the reinforced concrete; the supporting structures and shoring of the now hardened cement are removed, the supports are removed and the formwork detached from the ceiling with levers or other tools.

- In 90 % of cases carpenters work with incomplete scaffolding:

a ) - in 50%  of cases  on  metal scaffolding some of the  securing devices are not in compliance with the instruction booklet and ordinary standards;

b) - in 70-80% of cases the assembly of the scaffolding is not undertaken in a workmanlike manner (lack of securing pins on overlapping uprights and part of the front or rear diagonal elements; 

c) - in 80% of cases , the non-compliance of assembly with workmanlike standards regards the lack of small stretches of guardrails (end railings) and the installation of guardrails without toeboards and/or stopper for the base of uprights.

 

8.2 Falling inwards

- In 40% of cases the metal scaffolding consisting of prefabricated frames is not close enough to the building due to the latter’s profile, leaving large openings between the scaffolding and the wall.

- In 90% of building sites there are distances of over 20 cm between the scaffolding and the building.

- In 50% of building sites the openings in slabs formed by stair-wells, lift-wells, air-wells etc. are not provided with suitable protection.

Chapter 1 - DESCRIPTION OF STAGE

 

The construction technique for reinforced concrete roof slabs is basically no different from that for the previous slabs; however, there may be architectural changes according to the design of the roof.

The roof slab involves the construction of the supporting structure of the laundry rooms and lift cabins; as stated previously, the pillars, beams and the roof slab are made according to the procedures used for reinforced concrete described in forms 6, 8.

These structures have heights varying between about  m 2.20 and m 4.00.

Chapter 1 - DESCRIPTION OF STAGE

 

The construction site worker or expert bricklayer traces the lines using a ruler, string, string holder and colouring in powder form if necessary.

The workmen unload the masonry and material from the lorry to prepare the cement mortar.

The workman operating crusher loads the mixer or crusher with cement, sand, pozzolan, lime and water; the operation takes place by opening and casting from the bags or by loading with a shovel. In 50% of cases (larger building sites) a pre-mixed mortar is used, ready for use and transported in bags with a dry weight of 25 kg

The mortar prepared on the construction site is brought to the work areas on each floor in skips with winches or a crane, or in a wheel-barrow and/or equivalent types of containers. The pre-mixed mortar is brought to the various floor in bags and mixed there. Masonry is handled with cranes or winches.

When using masonry, the bricklayers cut bricks etc. if necessary and builds the walls with manual tools, using fixed scaffolding and mobile platforms on trestles in order to reach high positions. For cutting masonry they use circular saws (clippers) for curtain walls or with manual tools for hollow bricks.

METHODOLOGY :

See Form 1

 

Chemical agents

 

Cement and mortar dust during the opening of bags for loading the mixer: 95% of the workmen do not use facemasks.

Allergy-producing substances (components of mortar): in 90% of cases they are handled without gloves.

Dust from mechanical cutting of masonry, in 30-40% of cases it is made in a dry condition, and in the rest with water; 95% of the workers do not use facemasks.

During the loading of the mixer and the wet cutting of masonry with the clipper, dust samples were taken.

 

RESULTS

 

Breathable dust. The samples taken during the mixer loading and wet cutting with the clipper gave the following respective average values: 1.12 mg and 9.26 mg/m3.

TLV-TWA inhalable dust: 10 mg/m3.

TLV-TWA breathable dust: 3 mg/m3. 

 

METHODOLOGY

 

Breathable dust. The examinations made on not otherwise classified dust (NOCD) were made using the UNICHIM M.U. 285 and M.U. 316 methods. The filters (F 47 mm, porosity 0.45 mm) were conditioned in a thermostatic oven before and after sampling and weighed on AA MOD. 200DS precision scales, minimum scale 0.01 mg. The samples were taken with a Zambelli ZB2 air pump for high and low flows and with in stainless steel test containers with the Lippman method.

Sampling time

a) Mixer loading, the samples were taken for 60 minutes on a volume of 800¸900 litres.

b) Wet cutting clipper, the samples were taken for 50¸60 minutes on a volume of 700¸900 litres.

 

 

COMBINED OR ORGANISATIONAL

 

M.M.C.: in 30% of cases of cases the lifting and carrying of 50 kg bags (cement and lime) is undertaken by one worker only due to the lack of training and information of the workers; mixer loading is undertaken with a shovel, with workers often bending and twisting their backs.

Chapter 1 – DESCRIPTION OF STAGE

 

The construction stages of the walls proceed as for external filling (see Form 10), except that fixed scaffolding is not used since work takes place inside the buildings.

The bricklayers install the wooden frames in the wall openings for the doors, fixing them with brackets using manual tools.

The grooves and holes are made in the walls for installing utilities, using manual tools, grooving machines and electric drills. A small concrete breaker is sometimes used.

Chapter 1 - Description of stage

 

The organisations supplying water, power and gas install the utilities themselves or by sub-contracting. With regard to urbanisation work, the distribution points are first determined and the various utilities of the building site are provided by them.

These outlet points supply the lines for the building with specific trenches being excavated for this purpose. Excavations are made starting from the building for laying the pipe to which the drain shafts and then the sewer lines will be connected.

The workmen the plumbing, heating and electrical material from the truck, delivering it to the various floors by the crane or winches.

The following elements are used for the various utilities: 

1) gas plant:

            a – upright pipe: welded or filleted steel pipe;

            b – internal pipes: coated welded steel or solid copper pipes;

2) water supply plant:

            - filleted galvanised steel or thermowelded polypropylene pipes;

3) heating system:

            - insulated copper pipe;

4) drainage and sewer system:

            a - PVC pipes cut with a handsaw and glued with silicone adhesive; 

            b – hot welded polypropylene pipes;

            c - joints with packing;

            d – cement shafts;

5) electric plant:

            a – corrugated plastic pipes laid in grooves and on floors;

            b – plastic boxes for connections, switches and electric panels.

Once the systems have been installed the bricklayers close the holes and grooves and secure the boxes with cement or plaster.

Chapter 1 – DESCRIPTION OF STAGE

 

The workmen unload the material from the lorry, loose or in bags, to prepare the mortar for plastering. They use shovels to load the mixer or crusher with cement, sand or other inert material, lime and water; In 50% of cases a pre-mixed cement plaster is used with only water being added. The mortar is prepared directly at the place of use or according to the capacity of the mixers on each floor.

The bricklayers apply the first coat and then the final plastering, using manual tools and carrying the mortar in small buckets; they work on fixed scaffolding. Increasingly (50-60% of cases) an automatic compressed air mixer is used, that sprays of more liquid cement plaster with suitable additives.

The surface still wet with the first plaster is smoothed by hand using a trowel; the next layer of finer mortar is then applied (glue) and then the plaster itself, before finishing with paint.

Chapter 1 – DESCRIPTION OF STAGE

 

The material for the mortar is unloaded and carried as in the previous stages.

The cement mixer or automatic mixer is loaded with cement, sand and water; the mixture is then brought to the various floors with crane and winches, using skips, or propelled with the mixer pump.

In the larger building sites (50-60% of cases) the mortar is brought already mixed in the cement truck; the cement mixer pump is used to lay the cement.

On the top floor, a heat insulating material consisting of polyurethane, honeycomb cement and expanded clay or vermiculite is laid on the floor slab. After the cement coating, the waterproof coating is laid, and after a further cement coating the flooring is laid directly or with glue.

On the other floors, once the cement is laid, the tilesetters install the floor tiles, trimming them if necessary with the clipper or a manual cutter. The glue is applied to the base with manual tools and the floor coating is laid; the spaces are filled with semi–liquid cement or plaster, which is then cleaned with damp sawdust.

For bathrooms and kitchens the tilesetters use pliers or a portable grinder to shape the coating material in order to allow for the passage of pipes and electric and plumbing fixtures. The glue is then used to apply the coating.

The floors of basements and garages are made with smoothed cement mortar using the appropriate machine (surfacer).

Chapter 1 - DESCRIPTION OF STAGE

 

A straight section excavation with a depth of mt 0.50 is made with a mini-excavator and/or by hand.

The steel fixers build the reinforcement with cut and shaped steel rods and stirrups. 

The carpenters make the formwork with precompressed wooden panels and prepare the site for casting.  If the wall is designed as a retaining wall, an electrowelded grill (section 6 mm) is placed on the internal side of the panels. If the walls are to be left with plain cement, the carpenters spray the stripping oil on the internal side of the form, using the specific pump.

The size of the reinforcement and formwork vary according to the wall to be built; generally perimeter walls are 1 mt. high and 40.50 cm thick.

Sand, cement and water are mixed in the cement mixer; the mortar is brought in wheel barrows and poured. More often (60% of cases) the mortar is brought already mixed in a cement truck, with the cement poured down the extendible slide.

After the removal of the formwork the wall may be left plain, coated with masonry or painted (see Forms 30-37). The upper part may be covered with a travertine slab (see Form 34).

Chapter 1 - DESCRIPTION OF STAGE

 

The workmen unload the material from the lorry. Sand, cement and water are mixed in the cement mixer; the mortar is brought in wheelbarrows to be site to be paved.

The masons pour the cement and spread it with manual tools.

In the larger building sites (60% of cases) the mortar comes ready mixed from the cement truck; it is poured down the extendible slide of the cement truck or pumped.

After the preparation of the adhesive-water mixture, the tilesetters lay the paving material, cutting it when necessary with a clipper or hand cutter, according to the type of material used (clinkers, cement tiles, porphyry). The adhesive is applied on the base with manual tools and the coating laid, with spaces between the tiles being filled with semi-liquid cement.

In some cases part of the external areas are paved with asphalt.  In this case the area is prepared with a roller, the asphalt conglomerate is laid and then compacted with the roller, and finally spread with coarse sand.

RESULTS

 

None of the values observed in the activities of asphalt-laying and laying waterproof coating on terraces, the asphalting of roads and the unloading of tar at the firm producing the asphalt have been determined with regard to the volatile fraction.

 

METHODOLOGY

Sampling. Samples were taken with the Zambelli Mod. 2 LE personal sampling device for low flows, aerosol absorption on PTFE filters porosity 2 mm according to the NIOSH 5515 method. For the volatile fraction of the APH,  I.P. Zambelli Mod. TK 200 passive sampling devices were used..

Analyses. The analyses were conducted with gas chromatography with a mass detector; the accuracy of the method is 0.3 mg.

Sample timing:

a) Personal sampling: sampling lasted 120¸180 minutes with a constant flow of 2 l/min. for a sample volume of 240¸360 litres.

b) Passive sampling: sampling lasted 120¸180 minutes.

No protective devices were used for the respiratory tract in virtually all of the cases. 

 

COMBINED OR ORGANISATIONAL

 

M.M.C.: in 30% of cases of cases the lifting and carrying of 50 kg bags (cement) is undertaken by one worker only; most of the work takes place on the ground, with workers often bending and overloading their backs.
