6- Place only the edge of the Q-tip at the top the Flame. 7- Remove it when you see the of light being given off to avoid burning the Q-tip. 8- Clean up procedure: Discard used Q-tips to the bin, cover back compounds and put them up in a safe place, pour away distilled water in the sink, disconnect the Bunsen burner and clean it if stained,clean the lab test surroundings with paper towel to ensure no stain is left, wash your hands remove your goggles only when all equipments have been placed in safe places.

An intact skin is the body’s first defense against infections. Wounds expose components that are well protected from the outside by skin and mucous membranes. Many of these components (exposed) provide receptors for these opportunistic pathogens. Infections are very often the result of normal flora present on the skin and other parts of the body. Abscess: localized collection of pus Infections associated with traumatic injuries, such as animal or human bites, burns, cuts, frostbite, or penetration of foreign objects.
Infection- This is an invasion by and multiplication of pathogenic, micro-organisms in a bodily part or tissue which could cause harm. Infections can be spread with ease, poor practice is the main reason for spread of infection. Examples of poor practices are not washing your hands regularly, hand washing should be done thoroughly with soap and water for at least 20 seconds, followed by hand-drying with a paper towel. Another example of poor practice is not covering your mouth when you cough or sneeze. You should always get vaccinated and always use safe methods of cooking and preparing food.
Once the infection has occurred the bacteria produce a toxic gas that kills muscle, providing an even more anaerobic area, which explains such rapid spread in the body. It is the gas that kills the surrounding muscle not the actual bacteria (Reed 2004). Diagnostic tests and treatment. There are usually very strong visual signs specifically attributed to Gas Gangrene that do not even require any testing such as large liquid or air filled blisters that have a red or brown color and an odorous discharge. Usually air can be felt beneath the skin and incapability to contract the muscle in the area of infection (Reed 2004).
Reiter syndrome (Assignment Data) Introduction: Reiter or Reiter' s syndrome is a type of reactive arthritis, meaning that it happens as a reaction to a bacterial infection in the body. The infection usually occurs in the intestines, genitals, or urinary tract. Reiter syndrome includes joint swelling and pain (often in knees, ankles, and feet) along with inflammation of the eyes and urinary tract. It is not contagious, but the bacteria that trigger it can be passed from one person to another. There is no cure for Reiter syndrome, but you can control the symptoms.
* Clinical staff are issued with special PPE to help clear spillages * When filters from chair leak – floor is flooded with sodium hypochlorite 1% * All staff trained to maintain good housekeeping standards * Spills cleared up immediately Are current precautions effective : Yes, as there have currently been no accidents Problems and issues: The leak from the chair and the filters has caused the floor in surgery 2 to become a hazard because it causes a slip/trip risk & bodily fluids which are a source of infectious micro-organisms (bacteria,viruses and fungi) leak from the filters. This becomes a risk/hazard because infection could happen following hand to mouth/nose/eye contact or via broken skin. Furthermore cleaning products used to clean spillages may contain hazardous substances such as biocides and surfactants which could cause irritation, dermatitis and breathing problems. Suggested improvement: Speak to practice manager to discuss maintenance and repair of chair. Discuss the hazards and risks involved if chair were to remain in its current
However the use of an inert gas makes this type of welding less portable than arc welding which requires no external source of shielding gas. During the welding process, we are observed and analyze the performance of each types of welding in this experiment. Technician start welding process with Metal Active Gas welding (MAG). This welding use 1.2mm copper coated filler wire and mixture of shielded gas contain 80% of argon plus 20% of carbon dioxide. The coating of copper filler wire is to improve arc performance and to protect it from rusty.
Untreated, the skin may darken and become leathery and cracked. Allergic contact dermatitis can be difficult to distinguish from other rashes, especially after it been present for a while. List practical steps which can be taken to avoid the condition: Occupational allergic contact dermatitis can be avoided by personal hygiene, engineering control methods, good housekeeping, and personal protection. Personal hygiene, including hand washing, is very important to prevent contact dermatitis, but workers should be aware that excessive hand washing with soap and detergents can also damage the skin. Engineering control methods involve the enclosure of processes to separate workers from the harmful substances they work with.
Steel is any range of alloys of iron and carbon that contain less than two percent carbon. Typical structural steel is iron whose properties have been optimized for structural purposes by controlling the amounts of carbon and other elements in the metal, usually less than three-tenths of one percent carbon. Although steel will not burn, steel expands and softens when heated which typically leads to steel losing its structural integrity. This means that steel must be properly fireproofed in order to prevent structural failure. Structure fires are not hot enough to melt the steel, but the fire is able to weaken the steel significantly.
If the energy is too low, pigment will not fragment and no removal will take place.” There are side effects to laser tattoo removal. Redness, itching, burning, swelling and if not treated properly, there is a chance that it can become infected or may develop acne such as in laser hair removal. But if treated properly, laser tattoo removal is one of the least risky forms of removing tattoos. Experts recommend that laser tattoo removed skin be treated with the upmost care. Much like treating a newly tattooed piece of skin.
