3. DISCUSSION AND RISK CONTROL 3.1 Risk control Risk control involves identifying the method to eliminate or control the risks. The measures needed are listed in order of priority before taking action which involves the workers. To do this, the hazards at source must first be controlled such as by elimination or substitution. For instance, certain azo dyes likely to form carcinogenic substances during dyeing process should be replaced by non-hazardous or less hazardous ones.
Dye penetrant inspection method 1. An inspection method for locating surface cracks in non-porous material, you put a penetrant which enters possible cracks and the penetrant is pulled out by a developer. 2. The type of cleaners that is used when performing a dye penetrant inspection is detergent, solvents, etching chemicals, alkalis, paint removes, salt baths, acids, and penetrant application. 3.
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.

6. Wash, dry and observe under oil immersion lens. Differential stains render one type of microbe one colour and other types of microbes another colour. In the Gram stain, Gram positive organisms retain the primary dye complex (crystal violet-iodine) whereas Gram negative cells loose the primary dye complex during the challenge rinse. Most differential stains have a challenge step that follows staining with a primary dye.
What is a peroxide killer? After bleaching the cellulosic fiber with hydrogen peroxide, the fiber is subjected a thorough hot wash cold wash and neutralization processes. These operations would remove all superficially available chemicals that were used in bleaching process. However in practice it is found that the core alkali i.e. the alkali due to the use of caustic soda or soda ash and hydrogen peroxide, wetting agents and other auxiliaries would remain in the core of the fiber processed even after 2 or 3 washes.
In the correct stage of hair growth, which in anagen, the hair is fully filled with the melanin and the follicle in fully attached to the blood supply which at the proliferation stage will absorb the light optimumly. Moreover, cooling method in the laser machine help to protect the tissue surrounding by lower the temperature of the skin. By adjusting the parameters such as the pulse duration, fluence, and wavelength in to the right position, it will optimally destruct the hair follicle and minimize the dermal damage. Furthermore, the destruction of the hair follicle can be achieved by three mechanisms. Firstly, from the photothermal, which the light in specific wavelength (600- 1100nm) is absorb by the melanin and heat up the hair shaft.
How to wash your hands Washing your hands properly is an easy way to avoid getting and spreading viruses and germs. First, remove all rings, watches, bracelets, or other jewelry on hands and wrists. Jewelry can carry pathogens and should be cleaned with a disinfectant separately, so they will not be damaged. Next, stand close enough to the sink to reach the flow of water without touching the sink with your body because the sink itself should be considered contaminated. By standing too close to the sink it may spread any contamination to your cloths.
Jewelry has small crevices that can hold microorganisms. Sweat, dead skin, and dirt can combine with the warm semi-moist skin and harbor under the jewelry and cause bacterial growth. The removal of jewelry and watches will enable thorough washing of hands of wrists. While removing jewelry look around the sink area and make sure there is adequate liquid soap and paper towels within reach. One important thing to remember when preparing to properly wash your hands is try to avoid contact with the sink with your hands or clothing.
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.
Hand washing with soap & warm water should remove these transient organisms before they are transferred to surfaces, another patient or to a susceptible area on the same patient. In addition to washing with soap and water an alcohol rub will increase the removal of transient bacteria and should be used prior to clean or aseptic procedures, e.g. dressing changes, giving injections. Using an alcohol rub is a useful alternative when the hands are not visibly dirty, or when adequate hand washing facilities are not available. It is important that hand washing is carried out correctly to prevent the spread of infection.
