Content

In addition to responding to fire and medical emergencies, life inside a firehouse is packed with activity. HCDFRS career personnel work on one of three shifts (A,B,C). Each shift works for 24 hours at the fire station and then has 48 hours off. During the 24 hours on duty, personnel run calls, train, shower, eat and sleep at the fire station. Firefighters have a wide range of responsibilities, not only to hone the skills required of firefighting and medical emergencies, but also for the upkeep of the firehouse, equipment, and all the apparatus. All firefighters are on rotating schedules. Everyday activities firefighters engage in include:

  • Daily checks of all apparatus (checking fuel levels, examining for damage or wear, etc)
  • Inventory of supplies on the apparatus and in the station
  • Cleaning the fire station – to include the bathrooms, bunk area, mopping, etc.
  • Discussions of safety drills and creating safety messages to share with personnel
  • Daily training drills
  • Participate in mandatory fitness and conditioning program
  • Maintaining professional appearance and appropriate personal hygiene
  • Attend workshops or classes designed to inform firefighters on the latest advancements in medical technology, fire science, emergency treatment and prevention 
  • Cooking the meals

Discussion of recent or past firefighting, emergency medical responses and working out strategies to cope with unexpected occurrences during emergencies. 

Every activity is important and given attention, no matter how small it might seem!  A fire engine cannot respond to an emergency if it is low on fuel. A face mask can cause a fatality if it has a crack in it. A firefighter’s entire day is spent, in one way or another, preparing for emergencies. In our department SAFETY is the top priority!

Teamwork is another key component of HCDFRS. Modern fire stations have separate sleeping and bathroom/shower facilities for men and women. Older stations have been retrofitted with separate bathroom/shower facilities, but common sleeping areas remain. The Department makes every effort to provide the best available solution to privacy issues at each station.

Like members of the armed services, firefighters and EMTs follow a command structure based on rank, with firefighters and EMTs at the lower end of the scale. A paramilitary structure requires you to take orders from those of higher rank. When on duty, firefighters cannot leave the station to take care of personal business nor can they make or receive cell phone calls while en route to or working on an incident. Firefighters are expected to come work on time every day they are scheduled to work including during snowstorms, hurricanes or other severe weather.   Lateness is not tolerated. You are held accountable for your behavior – off and on the job, inside and outside Howard County.

Repair weld induced residual stresses in thick-walled steel pressure vessels (Technical Report)

Repair weld induced residual stresses in thick-walled steel pressure vessels (Technical Report) | OSTI.GOV

  • Other Related Research

If a flaw requiring corrective action were to be found in an operating nuclear pressure vessel, there would be considerable safety and economic implications. Should such a flaw be found, one possible corrective action would be an in situ repair weld. A repair of this type would presumably involve grinding away material in a region encompassing the flaw and then filling the resulting cavity with weld metal. Thermal stress relieving under those conditions could lead to serious difficulties associated with thermal expansion and warpage and would therefore most likely be avoided. Such a departure from normal procedure raises questions relating to residual stresses and material toughness levels which would have to be assessed before a repair could be recommended or approved. The residual stress measurements reported are intended to provide baseline information to aid in an assessment should such a repair ever have to be seriously considered.

Any, even the highest quality asphalt concrete pavement, is subject to destruction. It is possible to significantly (for several years) postpone its beginning by coating asphalt concrete with preservative protective and restoring impregnations AsfaTop or AsfaTop-SUPER , but sooner or later cracks begin to appear on its surface. Small at first, becoming longer and wider over time, they make a significant contribution to the destruction of asphalt. High-quality crack control is one of the most pressing problems of maintaining asphalt concrete surfaces, requiring expensive equipment and materials, a lot of time and a large number of people involved in these works.

Can some of these components be minimized by simplifying work and reducing the amount of equipment and people involved?

This issue is especially relevant in small farms that cannot afford expensive repair equipment or in those organizations in which the repair of asphalt concrete pavements is episodic or non-core.

Parking lots (including underground and multi-storey car parks), gas stations, homeowners associations, owners of cottages ... In general, everyone who owns or maintains paved roads and sites and does not have the opportunity (funds, desire) to order expensive repairs from road builders .

BORNIT Rissflex - Cold Crack Repair Sealant

Highly elastic bitumen emulsion modified with synthetic materials with special agents for repairing cracks in asphalt. When dry, the material is weather and UV resistant. The product does not contain solvents and after drying it becomes a highly elastic bridging crack protection against penetrating surface water. Penetrating into the crack on the asphalt to its entire depth, soaking into all the microroughness and pores of the asphalt, BORNIT-Rissflex has a particularly strong adhesion on asphalt concrete surfaces.

Repair cracks in asphalt without cutting!

You will need a minimum of conditions and equipment for sealing cracks with cold sealant BORNIT - Rissflex.

1. The weather should be warm and windy (from +5 and above). In the short term (4-6 hours) there should be no rain.
2. Rigid broom or brush (car brush), it’s good if there is something to blow through the crack ... (for example, garden leaf blower )
3. corner for leveling the applied sealant and forming the correct shape of the seam. The corner can be made independently from metal or plastic.

One person can do all the work!

Cracks in asphalt repair without cutting

BORNIT — Rissflex does not require preliminary cutting and crack cleaning. With the help of Rissflex sealant, sealing asphalt cracks is simplified and cheaper. Sealant (cold-applied crack mastic) is simply applied to the unprepared crack and leveled with a corner.

Watch

However, in order to ensure a high quality of filling cracks in asphalt and based on our own experience, it is better to follow the following recommendations:

  • The weather for sealing cracks in asphalt should be warm and windy (from +5 and above). In the short term (4-6 hours) there should be no rain.
  • The surface of the crack on the asphalt must be dry (wet crack is allowed, but without water standing in it - in this case the sealant will dry longer).
  • It is advisable to clean the crack in the asphalt as much as possible with a brush or a hard broom from the earth and debris that have accumulated in it and blow it out (for example, with a garden leaf blower). Otherwise, when repairing a crack in the asphalt, dust and dirt will worsen the adhesion of the sealant.
  • Cold sealant BORNIT – Rissflex with a small “slide” is poured into the prepared crack on the asphalt and leveled with a corner. By the way, this method - with a corner, refers to cases when you need to do the sealing of cracks in the asphalt with your own hands. For larger and / or periodic work, semi- or professional equipment is needed, but more on that below.

    If the crack in the asphalt is deep, the sealant will flow into the crack after a few minutes. A depression will appear on the surface of the crack sealed with sealant. In this case, you will need to add crack sealant (crack mastic) and level it again with a corner. Do not delay this processbecause the sealant dries and a film forms on the surface. Re-leveling the sealant with a corner will scrape off this film and although this will not affect the quality of the seam, the seam will look less aesthetically pleasing.

    Rissflex Crack Sealant will dry, depending on weather conditions and crack size, from 2 hours to 24 hours. Moreover, inside a crack on the asphalt, it can dry up to several days. Dry, windy weather will speed up the drying of the sealant. First, a thin film forms on its surface (tack free), then the edges dry up and although it is still damp inside the crack on the asphalt, the sealant is no longer afraid of rain.

    If for some reason it is not possible to close the area to be repaired for a long time, freshly applied BORNIT-Rissflex sealant can be densely sprinkled with granite chips (3-10 mm) on top. Due to its size, granite chips will allow the wheels of cars to pass over the non-hardened sealant without “spreading” it. In addition, granite chips pressed into the sealant and frozen in it will ensure the strength and roughness of the coating. In this case, traffic can be opened after about 30 minutes.

    Asphalt Crack Filling

    For a better and faster repair of asphalt cracks with BORNIT-Riessflex sealant, you can use a small-sized portable device based on an industrial sprayer, which allows you to inject sealant into a crack under pressure, thus achieving complete crack filling and at the same time level the seam with a square ensuring its correct shape in one pass. There are devices with a capacity of 5 and 10 liters of sealant in a portable version and on a trolley.

    In civilized Europe, cold sealant for cracks BORNIT - Rissflex is used on an industrial scale. Particularly for repairing the central joint on paved roads. Since the collapsing seam is, as a rule, of considerable length, special machines are used to apply the sealant - Rissomats .

    They allow you to quickly and accurately apply sealant. In order to open traffic on the repaired area without waiting for the sealant to dry completely, approximately 30 minutes after the work, immediately after its application, the seam is sprinkled with fine granite screenings (3-5 mm), for which the distribution hopper Shtrofix

    is used How to repair cracks on auto glass

    Auto glass is subject to many risk factors: vibrations due to traffic, temperature fluctuations, road and weather conditions, heat and cold, and much more. It is not surprising that for these reasons, car windows are damaged from time to time, which are best repaired in specialized services.

    What is a crack, how it differs from other types of damage

    Cracks on auto glass are expressed by one or more lines that vary in length. In addition to cracks, damage to the glass of a car is also considered chipped.

    There are six main types of cracks and chips on the windshield from the impact of a stone flying out from under the wheels of a vehicle in front or other objects.

    Let's take a closer look at them:

    1. Round chip. This damage is round and penetrates the first outer layer of glass, leaving a cone on the windshield with a deeper point of impact. These chips can vary in severity. It is important to inspect them as soon as possible, as this can lead to further damage to the windshield. In most cases, glass replacement is not required if there is no dirt at the base of the crack that cannot be removed or if the crack is just over 2.5 centimeters in diameter.
    2. A crescent-shaped crack can be compared to a partial or half bullseye. Crescent damage is usually not as severe and is unlikely to cause new cracks to develop or propagate. If the crack does not exceed 3 centimeters in diameter, it can be repaired without much cost.
    3. Star. In cracks of this type, damage rays diverge in all directions and have a shape. If the cracks do not cover the driver's field of vision and its diameter is less than 7.5 cm, they can be repaired. If not repaired immediately, cracks can spread further, requiring glass replacement.
    4. Double-sided crack. Through damage to both layers of triplex. Virtually beyond repair. This type of crack starts at the center point of the windshield. Specifically, if the crack is not within 5 centimeters of the edge of the windshield, it qualifies as a floating crack. This vulnerable area of ​​glass is particularly susceptible to cracks that can propagate.
    5. Combined crack. Damage with multiple characteristics, such as a star inside a bullseye crack. This crack is usually accompanied by extensive damage with the loss of whole pieces. Usually these tears are more severe and require windshield replacement if the damage is larger than five centimeters and is not near the edges of the windshield. It is also important to determine if the break has penetrated the second windshield layer.
    6. Combination of cracks of different complexity. The damage is similar in characteristics to a star, but has less branching of cracks. If the length is long, it cannot be repaired.

    In addition, there is another type of damage to auto glass called a stress crack. This crack is caused by sudden changes in temperature. Stress cracks are usually straight and start at the edge of the windshield and can easily shatter the entire windshield.

    First steps when a crack is found

    If a crack occurs on the auto glass on a long trip, then the following steps should be taken to allow you to get to the car service:

    • Seal the crack with transparent tape.
    • Coat the damaged glass with clear varnish.

    This will temporarily prevent the crack from expanding and minimize the ingress of dust and dirt into the damaged area.


    Crack repair or glass replacement?

    Can be repaired if:

    • Repairing the damage will not reduce the vehicle's safety in the event of an impact or collision.
    • Crack shorter than 15 centimeters or impact chip less than 2.5 centimeters.
    • Only the outer layer of glass is damaged.
    • The crack or chip is not close to the outer edge of the glass.

    Replacement is required if:

    • The windshield is damaged to such an extent that it impairs the driver's view.
    • The crack is longer than 16 centimeters and the chip is more than 8 centimeters.
    • The inner glass layer has also been damaged.
    • The damage is close to or reaches the corner or edge of the windshield.

    Crack Repair Technology

    The essence of the repair is pouring polymer into the outer layer of the windshield, restoring its shape and structure, and improving the appearance of the glass. When cured and polished, the polymer leaves a smooth surface and prevents crack propagation.

    If the damage has reached the middle layer of the windshield, the cracks must be deepened or widened with a drill. This is necessary in order for the polymer to reach the middle layer, where, after UV treatment, it will harden and glue the damaged surface. It should be noted that all repairs should only be carried out after dust particles have been removed from cracks and crevices using a small vacuum cleaner designed for this purpose. At the end, the restored part of the glass is polished.


    Repair Equipment

    Most crack repair services use special equipment that allows you to quickly restore damaged auto glass. It may include: an injector, a drill, a vacuum, a set of drills, blades, a polymer, a UV lamp and other tools.

    How to choose a service

    When looking for an auto glass repair service, you should pay attention to the following factors:
