Contamination depending on the physical state of the hazardous substance

Hazardous substances can occur in solid, liquid or gaseous form.

Influences of the contaminated surface

Physical and chemical properties as well as their surface properties are decisive for the behavior towards contamination.

Dense and smooth surfaces
have a high resistance to the penetration of hazardous substances (e.g. glass and metals, baked-on paints).
Porous fabrics
have a low resistance to the penetration of hazardous substances (e.g. masonry and wood, air-dried paint).
Plastics
can have different properties. During diffusion into the plastics, reactions with plasticizers and color pigments can occur, which often lead to embrittlement, swelling or detachment. After the rough cleaning, it can be assumed that the pollutant has been removed from the surface, but may still be present in the depth of the material. Due to the undirected movement of the particles, they can emerge from the surface again and change into the gas phase. The particles migrate faster with increasing temperature. This is used for decontamination.

Use of chemicals for fire fighters: Unknown people deposit barrels with used oil and chemicals

Homburg Unknown people have deposited several old barrels with an unknown chemical liquid in a forest near Jägersburg. The fire brigade moved out to use chemicals, the Kripo determined.

Because of a large number of old barrels and canisters with previously unknown chemical liquids, there was a large-scale deployment of the police and fire brigade on Saturday in a forest area between Jägersburg and Waldmohr - behind the so-called old train station in the direction of Spickelweiher. As the police announced on Sunday, the barrels must have been unloaded on the meadow between September 18 and 19. There are presumably used oil in some barrels. However, some barrels leaked, so that the toxic substances leaked and seeped into the ground. The fire brigade then closed the promenade there and set up a safety zone around the scene of the incident. The State Office for Environment and Occupational Safety took samples on site. The Kripo was also turned on. 16 firefighters from Homburg and Jägersburg as well as the Homburg construction depot were on duty and recovered the barrels. Because of their dedicated work, there was only superficial contamination that could be removed.


Fire brigade moved out to use chemicals at Nawi

On Friday morning, dangerous goods were deployed at the natural science faculty of the University of Salzburg in Nonntal. The professional fire brigade moved out with 17 men.

On Tuesday, 17 men were on duty at NAWI in Salzburg-Nonntal because of a chemical that had exceeded its expiry date. If a chemical gets older, it can become dangerous, according to the fire brigade. According to initial information, however, no major damage should have occurred. "We left almost without having achieved anything," confirms the head of operations. Police experts now want to examine and dispose of the explosive chemical

Use of chemicals in residential areas

Chemnitz- The Chemnitz fire brigade was on duty in Further Straße on Tuesday morning. The police suspected dangerous chemicals during an apartment search and asked the fire brigade for administrative assistance.

Special forces arrived around 9 a.m. and prepared a chemical mission with appropriate protective equipment. A drug detection dog was also used.

The police had applied for the search warrant because the tenant was being investigated for violating the Narcotics Act.
Apparently no dangerous substances were found in the apartment.

Fire station 2, which is specially trained for such dangerous missions, was in action.

The fire brigade in chemical use - chemistry and physics

[Update 6.15 p.m.] Plettenberg - The Plettenberg fire brigade's work in an industrial company on Königstrasse has ended. Around 30 emergency services from the Plettenberg fire brigade spent more than three hours in summer temperatures, wearing chemical protective suits to stop the escape of 30 percent hydrochloric acid from a container.

Around 150 liters of the medium had leaked into a warehouse due to a technical defect and had spread in the hall.

Thanks to internal preventive measures, the hydrochloric acid could be discharged into an emergency container. For this reason, there was no danger to the environment at any time.

In addition, the firefighters diluted the acid with water and knocked down any vapors that had initially triggered the fire alarm system. Here, too, it was possible to prevent vapors from escaping into the open, thus preventing a danger to the population here as well.

For the duration of the operation, the police had completely blocked the access road "under the green mountain". A disposal company is currently on site to clean the hall and dispose of the collected liquids.

The full-time workers from the fire and rescue station, including the management service, as well as fire engine 1 of the voluntary fire brigade, consisting of the fire fighting groups Stadtmitte and Landemert, were on duty.

The fire brigade cannot provide any information about the exact cause of the accident and the amount of damage incurred.


Exercise of the fire brigade of chemical use with NBC train in Hassel

Hassel The members of the St. Ingbert volunteer fire brigade mastered a tricky exercise scenario. As the fire brigade reports, the forces from the Hassel fire-fighting area drove to the elementary school in Hassel on a practice evening.

Real firelight and smoke development could already be seen on arrival. A fire in the basement of the school was simulated by the situation representation. The exercise participants mastered this according to the standard.

But then the situation of the exercise changed, as the fire brigade further explains. During the extinguishing work, the attack force, wearing heavy breathing apparatus, discovered that dangerous chemical containers - some of which had leaked - were spread out on the floor in the basement. This change of position led to the second part of the scenario.

A fire brigade's press spokesman, Florian Jung, cannot handle an application scenario with dangerous substances for a fire fighting area alone. That is why the specialists from the ABC train south of the Saarpfalz district came into action. This train consists of volunteer fire brigades from St. Ingbert, Blieskastel and Mandelbachtal. The special forces are deployed to clear up and ward off nuclear, biological or chemical dangers. The special forces are equipped with chemical protective suits to ward off chemical hazards. In this way, leaks of hazardous substances can be contained and the substances collected. When picking up the substances and packaging, the forces are particularly required, as reactions of escaped alkalis and acids can occur at any time. Another challenge is the final decontamination of those involved. The workers are professionally cleaned in a special tub so that the contamination cannot be carried over and the hazardous substance cannot spread.

The two emergency services in full protective suits practiced packing the dangerous substances in the dark cellar. This is fundamentally difficult because several pairs of gloves have to be worn on top of each other. However, filigree work must be carried out by hand. The mission was over after around 20 minutes. This was followed by extensive cleaning, which can take up to ten minutes under real conditions.

Not only the two firefighters in the suits had their job. The approximately 60 firefighters in the schoolyard coordinated the operation, set up a cordoned-off security area, provided operational material, illuminated the area or took care of the management of the breathing apparatus.

Florian Jung, press spokesman for the fire brigade: “An ABC mission is always material, personnel and time-consuming. The aim of the exercise was cross-firing district cooperation. Working under the protective suits as well as putting them on and taking them off and the processes around them. These processes were successfully trained during the exercise. "

The forces of the fire brigade's ABC train conduct a joint exercise every month. This takes place alternately in the participating municipalities.


HFW Villach: Use of chemicals in Villach Landskron

Shortly before 2 p.m., the main fire station in Villach, together with the locally responsible Landskron fire brigade and the Zauchen fire department, were called to an unusual mission in the Landskron district. In the course of renovation work, excavation work was being carried out in the area of ​​the terrace of a single-family house when suddenly a heavy smoke billowed out of the earth.

This smoke development was noticed by fellow fire fighters from Landskron who were doing maintenance work in the immediate vicinity of the fire station. Some firefighters immediately rushed to the scene of the incident and evacuated the area around the exit point, as a pungent smell that was unusual for the location was perceived.

When we arrived at the site, a pollutant measuring device and a reconnaissance team with respiratory protection and protective clothing were sent into the excavation pit. With the presence of mind, the Landskron fire brigade comrades covered the exit point with a few shovels of gravel and thus reduced the reaction of the unknown chemical - explains HBI Harald Geissler, commander of the main fire station in Villach.

After the chemical readiness of the state of Carinthia had been notified via the control center in Villach, a respiratory protection team began to dig up the chemicals buried in the ground by hand and to separate them according to the type of packaging and chemical composition. Over 20 different chemicals, including hydrofluoric acid, sulfuric acid, phosphorus and various poisons, were gradually dug up and safely stored. Another group explored the immediately adjacent cellar and discovered that there was massive damage from the chemical vapor.

After all the chemical and poison containers had been recovered, an excavator driver carefully dug the area around the site under safety in order to examine the immediate area for further contaminated sites. Since no other hazardous substances came to light, the found containers were packed in transport and safety containers of the fire brigade in consultation with the country's chemist and brought to a licensed waste disposal company. The place of use and the cellar were then checked for measurable pollutants and measured.

After around 2.5 hours, the fire brigades were able to leave the site and carry out the necessary post-cleaning work in the armory.

In summary, it can be said that the quick-witted action of the nearby Landskron fire-brigade comrades initiated correct initial measures and recognized the actual danger. Due to the rapid evacuation from the danger area, neither the construction workers nor the house owners with their small children were injured by the dangerous contaminated site.

The main fire station in Villach with the hazardous goods train, the fire department Landskron and the fire department Zauchen as well as the country chemist on duty and a patrol from the Villach police were in action.


Fire brigades practice using chemicals

Stendal / Osterburg (rfr) l In order to be fit for operations in railway accidents, regular training is required by the fire brigades concerned in order to keep reminding oneself of the special features on and on the tracks.

This is what happened during a joint exercise of the blue coats from Osterburg and Seehausen in Stendal, where the focus last Wednesday was on the leakage of liquid or gaseous products from tank wagons. For realistic training, according to Osterburg's City Defense Manager Sven Engel, Deutsche Bahn AG has a special dangerous goods training train that stood in Rolandstadt for two days.

During their simulated deployment, comrades from the Osterburg and Seehausen fire brigades, who of course had to put on the appropriate protective suits, practiced sealing leaks on tank wagons with pneumatic cushions or sealing connection flanges. All in all, it was a sweaty and exhausting job in the early summer temperatures, Engel estimated, who and his colleagues could rely on the material and technical support from the fire brigade Technical Center and the Stendal fire brigade.

According to the announcement, the exercise lasted around three hours. 22 emergency services were involved in the training. The supply of the comrades on site was carried out by the Friends of the Osterburg Fire Brigade.


Leak on tank car sealed: chemical use at Westbahnhof

Aachen A chemical deployment at Aachen Westbahnhof kept fire service specialists busy for several hours on Tuesday. In the early afternoon, the leak was sealed on a tank car.

In the morning it was discovered that liquid was dripping from the tank car. According to a fire department spokesman, it is a waste product from the chemical industry. "The substance is explosive and toxic," said the spokesman. That is why great care had to be taken at the place of use.

The fire brigade was deployed with forces from the Hauptwache and Wache Nord, the CBRN train (for dangerous situations of a chemical, biological, radiological or nuclear nature), the fire brigade central and (as a precaution) the rescue service. The fire engines of the volunteer fire brigade from Laurensberg, Eilendorf and Sief were put on standby at the same time in order to ensure basic security for the city of Aachen for the duration of the deployment. Some tracks at the Westbahnhof were closed.

An employee of the Swiss Railways, who is responsible for the freight train, was also on site and supported the emergency services with specialist knowledge. The fire brigade was able to leave shortly before 2 p.m.
