Safety in the Construction of Wooden Frame Houses – Safe Work, Safe House

 

Often clients have questions, why do building works at the objects are going on this or that way, why do there are special requirements for work performers and technique and equipment, why do there are special procedures or “paper works”, why isn’t it possible to slip off a friend for the lower payment, who tells, that  is a fine specialist in the building field. In short, why does the process of building easy summer houses become so hard? For all these questions there is only one answer – to provide security for all – both clients and builders.

Safety in the Construction of Wooden Frame Houses – Safe Work, Safe House

Often clients have questions, why do building works at the objects are going on this or that way, why do there are special requirements for work performers and technique and equipment, why do there are special procedures or “paper works”, why isn’t it possible to slip off a friend for the lower payment, who tells, that  is a fine specialist in the building field. In short, why does the process of building easy summer houses become so hard? For all these questions there is only one answer – to provide security for all – both clients and builders.

The advantages of the wood in the process of building of the house

Wood is a traditional and modern building material with a huge use in the building (wooden houses), carpentry, interior etc. When wooden houses are built right or wooden carcas panel houses are durable, they are more durable than traditional brick or concrete houses, which after year decades start to lose their characteristics. Wooden houses give healthy air quality, healthier sleep.

Advantages of the wooden house:

  • Long-lasting;
  • Economy;
  • Security;
  • Health.

Nowadays without a permission, it is impossible to build any building

Nowadays people build different houses. Sometimes planned object is so easy and made with hands, that an owner cannot even imagine about the project (private house project) or the beautothe necessity. That’s why, especially because of the necessity of the of your own security, you have to go to the building board to permit necessary documents.

• Cabinet Regulation No. 500 “General Building Regulations” buildings are divided into three groups depending on the complexity of the construction and the possible environmental impact.

• The first group includes the so-called small-scale one-storey buildings, including awnings and ancillary buildings with a construction area of no more than 25 m2, and other small buildings.
• Construction of all buildings (including small ones) requires coordination with the local building board.
• Construction of low-rise buildings (low-rise construction) is harmonized in a simplified manner.
• Construction management must harmonize all types of engineering structures, such as the installation of a new fence.
• An arbitrary penalty is imposed on arbitrary construction.

In Latvia at the moment the electronic harmonization of construction intentions has been implemented. Read more at Building Democracy.

In accordance with the normative acts without permission it is possible to do cosmetic repair (wooden house) – a painting of walls or wallpaper replacement, new bath or sink installation, but not without prejudice to load bearing or bearing (wood) construction, engineering communication, and also without exceeding permissible level of the sound. In this case, neither a construction project nor a construction permit, nor a simplified renewal certificate card is required. Unfortunately, in the field of the building, the owner does not have any huge freedom before starting to build something (wooden house) or rebuilt, the most appropriate step about the future action is to ask everything in a local construction board.

Work security in the building field

In the building field, there is a new object (private house) building, exciting object repair and reconstruction, mounting of the prefabricated house elements on the building site, and also the building of the temporary buildings. One of the more common types of construction is the general (private house) construction. Full cycle buildings (for example, living buildings) and civil engineering (for example, highways, streets, bridges, tunnel, construction of railways, airfields, ports and other hydroelectric structures, irrigation systems, sewage systems, industrial complex structures, pipelines and power lines, sports structures) building. Requirements of the work safety (of the individual houses) field is regulated Cabinet of Ministers February 25, 2003 Regulations Nr. 92 “Labor protection requirements in the course of construction work”, the Labor Protection Law and other normative acts in labor protection.

When looking directly at the safety and health conditions of employees, the risk factors in construction objects can have a significant impact on the health of employees. Most often, this can happen in the event of an accident, resulting in various injuries.

When looking directly at the safety and health conditions of employees, the risk factors in construction objects can have a significant impact on the health of employees. Most often, this can happen in the event of an accident, resulting in various injuries.

Of course, it should be taken into an account, that disregard of the work safety can occur economical losses (an equipment can be caused, building materials etc.), and also can suffer “the third persons” – employers of other employers, pedestrians and riders or the other people, who are near the object. The pollution of the environment can happen (for example, chemical substances – color, solvents etc. – leak).

The most important risk factors in the building

Building field by its structure covers different works, for carrying out which are used very different technologies and equipment – from the preparing of the building site, installation of the communications, concreting, masonry, roof inner and outer interior works to different others, bigger or smaller specific works.

An important work environment risk factor groups in the building are these:

  • mechanic and traumatic risk factors (work in high, work with an equipment, stumbling and falling, collisions with heavy equipment, electric traction, etc.);
  • physical factors (not appropriate microclimate and adverse weather conditions, lightning, vibration, sound, ultraviolet radiation, and infrared radiation, for example, welders etc.);
  • chemical substances, which can be caused in the process of the building in case using of harmful materials (concrete dust, lacquers, solvents, welder aerosol, hydro isolation and thermal isolation materials) and in the influence of which there are subjected concreting, lacquers, welder and makers of the interior;
  • dust (abrasive material dust by making slipping works, concrete dust, asbestos fibers by making works of demounting, using glass and stone wool);
  • ergonomic factors ((heavy, especially non-standard objects, moving building materials, forced postures, uniform movements at a fast pace, such as grinding, etc.);
  • psychosocial factors (long working hours, extra hours, stressed terms, too high workload, long hours till objects etc.);
  • biological factors (hepatitis A, for example, plumbers, who have possible contact with canalization water, tick-borne encephalitis, and Lyme disease if the work is done in a green area (for example, during construction site preparation), u. etc.In the building (especially in the private house building) there are possible different risk factors. Very often many of the work environment factors are acting at the same time, thereby they can step up the influence of each other. For example, at the same time happens vibration of all of the body, when working with a heavy equipment, also draft, and work in cold rooms work on scaffolds and adverse weather conditions (heavy wind, gust, rain, snow, etc.). It should be noted that these factors change very rapidly and depend on the work to be done, the size of the object and its complexity.Undeniably, there are such factors in the work environment that can not be avoided so easily:
  • A widespread environment factor in the building is a shout. It creates both different work equipment and heavy technique. Operation of each plant creates shout.
  • In the building very widespread work environment is vibration, such as shout, which is to be faced, when operating lots of plants, which, when working, creates not only shout but also vibration. Vibration in the wrist and in all of the body is pushing nerves and blood vessels, causing numbness and pain in the hands, as well as changes in nerves and blood vessels.
  • An everyday phenomenon in the building is chemical substances and dust, which arises both from the used fuel (exhaust gas) and from in the building used processing materials. (For example, abrasive dust, which arises from the wall sanding.) Part of the dust at the entrance to the body is holding nose hairs, large dust behind the throat and laryngeal mucus. The most harmful are microscopic dust, since pu-tufts are long-lasting in the air and capable of penetrating deep into the airways. Paint, solvent vapors, which are sometimes very harmful to health.

Development of the work security events

When developing the work security plan (private house building), you have to take into an account, that the work security system main goal is to provide a secure work environment for workers by shielding from injuries, sicknesses, and accidents. First of all, you have to plan those events, which fastly and straight will protect security and health of workers at the beginning, seeking to provide protection through collective remedies (for example, create an ability to move heavy load by using aids, not let to move them two workers), and only then – individual (for example, if it is impossible to choose less harmful colors, use respiratory protective equipment – face mask or respirator during dyeing).

The plan of the work security events is one of the parts of the inner monitoring, in which determine events of the work security, it implementation terms, chief persons for the performance and necessary materials or finances of the concrete work environment for preventing or reducing of the risk factors.

When choosing between similar meaning variants of the work security events, significant is to evaluate, which variant will be more profitable (to buy or rent aids for moving a load or to slip off workers). The compulsory health check is also part of the work safety.

The most important preventive events, when using building equipment:

  • Only use equipment that is up-to-date and suitable for work and to perform maintenance and inspection of equipment in a timely manner;
  • To inform workers about safe work techniques and necessary collective and individual security resources (for example, gloves, face and eyes security resources, working boots) using, and also regularly to repeat this information;
  • To save working equipment in accordance with these requirements and safety.

The most important preventive events, when providing safety in building sites:

  • maintenance of cleanliness and order in construction sites (including wiring and cable reconsideration, provision of transitions, a collection of nail boards and other dangerous objects, marking or covering of the ends of the reinforcement, collection of waste and unnecessary materials, etc.);
  • planning of delivery of the necessary materials on the building site in the amount, which do not disturb the working process, and people could free move in;
  • informing of workers about safe working techniques and necessary collective and individual protection aids (for example, working boots) use, also regular repeating of this information.
  • Fire safety

With a fire safety often is connected burning or not burning material building and materials. Buti n a reality, fire safety is the safety of people in the building – if the building starts to fire, people should have an ability to evacuate in a due time.

  • The bigger fire safety has a building, the more time people has to leave the place.
  • Smart creation of the heating system and qualitative installation o fan electricity definitely will help to reduce the risk of the fire.
  • Fire safety in wooden carcass houses

So you have to try hard to burn the wooden house,  wooden carcass panel house

ignite completely and it could burn fully. Nowadays wooden house building develops, technologically the wood is processing better and houses become more and more fire safe.

There are experiments about the ignite (watch the video here – an example), where, where you can see –  that a wooden frame house after an hour’s burning can show impressive fire-resistance results. In comparison – in a  keramzite blockhouse there is a fast reaction on the fire, so the first window can fall after seven minutes.

Meanwhile, wooden windows slowly shrilled, and the first wooden window could fall just over half an hour. Also, wooden houses or wooden carcass house beam after an hour-long burning bless only from the outer side, and thanks to this, wooden house roof even after an hour-long fire cannot be offended.  Metal beam loses its construction stability when it’s hot.

Significant cases to be taken into an account

When projecting and then building (wooden houses), the most important attention has to be paid on those elements and houses, where there will connect with a fire and heat. Fire danger objects are stoves, cookers and fireplaces, its connections to the chimney. They must be built with special building materials and finishing materials, such as various shamot products. And, of course, the furnace space with its installed heating equipment, which must be built in accordance with the requirements of the regulatory enactments regulating the construction, which provides for the use of fire-resistant materials – special plates and mortar. Doors of these rooms have to be fire-safe.

  • House owners have to keep up with the condition of the chimney, it fasteners in the roof and intermediate floorings. You have to be sure, that the chimney has a certificate of the match to the EU fire-safety standards when you choose it. Also, you have to check the guarantee of the producer.
  • The risk zone of the house is an attic, where there are usually wooden constructions and different isolation and insulation materials. To increase the fire-safety, it is necessary to proceed wooden constructions with fire-safe stairs – flame retardants. The insulator must choose non-combustible (for example, rock wool). Proper wiring, installation of electrical equipment and its everyday use are very important for fire safety (wooden panel house). Be careful with the use of high-capacity electrical appliances, including the operation of electric fireplaces.
  • If we talk about the safety in wooden houses, or wooden carcass panel houses, the owner of the building is responsible for its exploitation both about the property and exploitation on the right place.
  • Preventive events for reducing the fire risk in a wooden carcass houseIt is not enough of the correct proceeding, installation and building of the timber (wood). Each house liver has to be responsible against things around him. House owner can due to time do different events to reduce the fire risk in his property. The easiest way, how reduce the risk, is provide the fact, that burning things like paper, cardboard boxes, old books, clothes and things in places such as cellars, attic or garages are not stored in one place.  The things mentioned above is possible to put into waste paper, recycle or, for example, to give in to charity. The profit is double – safe house and free space. Smokings kills, everybody knows. But it is also harmful for the house safety, because for the smoking there are no specially installed place to avoid a situation, that completely not faded out cuddly will be thrown out together with burning materials. Each 10 years the electrycal system should be checked.
