9. Redevelopment of fungus-attacked equipment-objects (materials)

9.1. Prelude

Equipment-objects or household-textiles can as well as attack through grew over from mycelium or spores of the fruit-body of a wood-destructive fungus or are damaged. Independently from the proper Redevelopment of the building in accordance with the DIN 68800 part 4 is equipment-objects to view separately. If an affection for the covered area is, for example in the wood-great commissure-cover before, so a connection doesn't exist directly. Except the closet of wood and woodwork-material respectively stands on the arched board.
The factual position is different to assess, if fruit-bodies already refined massively in the affection-space, and a high spore-encumbrance is available or the equipment-objects were overgrown already from mycelium or from the fruit-body. In the last case respectively partially should detoxify objects from organic elements is detoxified. This always is dependent on the ideal one or dear-moderates value of the object. for example, a curtain or a carpet beside a fruit-body and these respectively already was attacked, is to be properly detoxified. The loss should be justifiable. Be a TV at the other corner of the space and the affection is relatively low, so no disposal needs is performed.
This shall like follows is justified:
Household-objects are drily, constantly become wash round from the air and constantly are controlled normally. In many cases, they don't represent any direct endangering for a new affection so. In principle, it should be decided responsibly here.

The rectification has to take place so that preferably no spores or myceliumteile over air-movement on other objects is transferred. On the floor and on not attacked household-objects, a PE-cover sheeting should be put on. After the rectification of the objects, the metal leaf is put together carefully and is cleaned up. Clothing and shoes are to be shifted after the measure and to like usually clean.

9.2. Sleek surfaces

These materials don't serve as food-basis. In particular cases, the aged dust and fat serve as food. Sleek surfaces of inorganic materials, leaves itself like metals, glass, ceramics as well as Plasterzeugnisse clean with water and household-clearers. Here, also sponge-fight-means could be used. After corresponding in-wirk-time, these are to be taken again away. Here, the corresponding processing-specifications of the manufacturer are to be heeded and to keep to corresponding body-protective measures. For refrigerators (interior) or similar it doesn't use since a contact with foodstuffs should not take place.

9.3. Porous materials

Partially can clean sufficiently porous materials (usually out of organic materials), like wallpaper, plasterboard-construction-plates, gypsum-fiber-plates or finery, stonework (porous) and disguise-plates normally or is restored respectively, since the mycelium grows normally through the material here or spores take root respectively in the pores. Here the redevelopment is to be performed 4 in accordance with the DIN 68800 part, and the corresponding safe distances are to be paused. Building-parts are to be restored from an accordingly qualified compartment-firm or respectively under technical care of a specialized expert.

9.4. Wood

Wood represents it main-food element of the wood-destructive fungi, to which also the real dry rot belongs. All attacked wood-parts are to be developed. Directly adjacent wood-parts should also be developed if this is possible. Here, it can be used up equivalently 68800 pages 82 footnote 4 to the wood-protection DIN after the implementations in the Beuth-Commentary. The safe distance long ago to the wood can be shortened by 0,5 m over the visible affection of the Substratemyceliums. Still, it can be deviated from the request of the removal of attacked wood-parts, if destroys the mycelium for itself through suitable measures, and a revival lets excluded. Wood-preventatives are not to be brought respectively continuous lounge in the residential-area to the usage. How fungus-unfavorable attested by a notary wood-preventatives dotal far later have a destroying effect in the wood, is not sufficiently scientifically examined. Here, hot air or law cases with gas (bromine-march gas) possibly last applicable also in combination with a preventive fungus-unfavorable wood-protection or microwave-technology. Individual wood-parts, like for example at the banister, can be done with a hot air-fan. Dry continually verifiable and from air accessible constructions doesn't represent any direct endangering. For example a free-suspended wood-stairway.

On sleek wood (boards) great commissures, hand-rails etc.) possible spores can be taken away without problems. (Of course not, if a well visible spore-work period of a fruit-body situated in direct proximity could develop.) With the distance, a spore-distribution is to be avoided through air-revolution. Sucking with a Vacuum cleaners with microfilter could possibly cause problems. The easily moist wiping off with wood pulp-household-cloths and afterwards immediately into a metal leaf-bag is is more useful. Further policy is to be performed furniture like in the point.
Woodwork-materials, like chipboards or fiberboards should developed and is detoxified. Through its porous structure and the distribution of binding agents, can be calculated through the entire cross section with a myceliumbefall. If wallcoverings of wood were in the damage-area, so these should not be installed again for the time being.

9.5. Furniture

Furniture, chairs and other usually have a closed surface-structure. This can veneer, a synthetic material-coating, wax or oil-work period is. An affection can restrict itself to the dust and fat-work period conceivably. The surface is moist to clean to dry and if need be with 80 per cent - y alcohol, to clean (disinfection). Working outside or with good aeration performs, since there is smut and explosion-danger. Furniture attack should be detoxified. Also, one could exchange only the attacked (with low size) individual parts, like for example the rear wall from hardboards. (Construction-markets cut the desired plate-sizes normally.) The remaining parts are treated like above named.

9.6. Household-ceramics

The are to be cleaned with usual household-clearer and water. Additionally, one can heat the non-flammable and shape-retaining objects into the electric oven with 150ordm;C and cirka 20-30 minutes. This temperature is sufficient in order to destroy most spores.
(Wood finds out a thermic change with a temperature under 100ºC barely, therefore this method is not meaningful for wood.)

9.7. Textiles

Equipment-objects with upholstery (chairs, sofa) and household-textiles (curtains) Auslegware, carpet and other) properly restores only with big expenditure leaves itself. Textile floor-coats from the damage-space should be disposed of. Curtains, that are not directly in the damage-area, can be cleaned as warmly as possible in the washing machine conceivably. The utilization of enzyme-washing agent could be on this occasion advantageous. Encymes solve albumin-links independently whether these are dead or living. In like wide itself this on the spores has an effect, cannot be named with determination. In this context, it should be pointed out to it once as well that spores are very resistant and extreme climatic conditions can survive. mycelium against it lets itself destroy more easily normally. for example, foot-fungi are not destroyed with a wash-temperature by 30ºC. Only from a temperature of 60ºC, a decrease takes place about the element 10.000 and with 90ºC, a complete deadened takes place. Equivalently, this should be taken into account when cleaning fungus-attacked textiles.
In the textile industry, certain textiles get, like for example socks, stockings, feed-materials wool blankets carpets for bathrooms and other, antimicrobial installation. That is chemicals, under the most different name like Sanitized, Actifresh, bioguard etc.) they to the usage against microorganisms come as they are used for de fight against fungi or as the growth-inhibiting. Tents and tarpaulins are claimed outside especially strongly before decay and deterioration. The cotton or the linen are partially protected with high-poisonous chemicals. These admittedly are not for a later disposal directly in the touch with the skin, however, it represents an environment-problem.
