Eye-wash bottles

Is all safety equipment, where applicable, in date for inspection/test, correctly located and in good condition, e.g. life-rafts, flare packs, life-rings/lines, man overboard smokes/lights, life-jackets, first aid kits, eye wash bottles, foghorn and VHF radio ... 

Is there adequate first aid provision, i.e. first aid kit, stretcher, eye wash bottles, at least one appointed person per shift ... 

Eye wash bottles and showers should be provided at strategic places throughout the plant. Gaseous emissions from safety devices such as ammonia gas refief valves must be vented to a safe place. 

The liquor can irritate the skin and can cause corneal ulcers if splashed into the eyes. Persons handling ammonia liquor must wear PVC gloves and gas-tight goggles. Eye-wash bottles and breathing apparatus, preferably of the self-contained type, must be available on site. In case of contact with the skin, wash off with water. If ammonia liquor splashes into the eyes, wash out with copious volumes of water or saline solution. 

When the reaction terminates, cool the retort in a chlorine stream, then displace the chlorine with a stream of dry carbon dioxide. Rapidly disconnect the retort from the wash bottles and remove the remaining unreacted metallic iron through its neck. Pour out the iron chloride through the tubulature of the retort into a preliminarily weighed dry test tube drawn out at its middle. Immediately seal the tube wear eye protection ) and weigh it. Write the equation of the reaction. Calculate the yield in per cent. 

Assemble an apparatus for the preparation of dry ammonia (Fig. 62a). To do this, put solid sodium hydroxide wear eye protection and handle the alkali with a porcelain spoon ) into two-neck bottle 1 or a Wurtz flask. Pour a 25 % ammonia solution into dropping funnel 2. Put soda lime or a granulated alkali into drying columns 3. Pour glycerin or vaseline oil (a bubble counter) into wash bottle 4. 

Assemble an apparatus (see Fig. 53a), replacing the second wash bottle with a dry U-tube (wear eye protection ). Pour a small amount of a 96% sulphuric acid solution into the first wash bottle. Put the U-tube into a bath cooled by a mixture whose temperature should be below —10 °C. Put 5-10 g of copper shavings into a Wurtz flask and pour the calculated amount of a 96 % sulphuric acid solution over them. Heat the reaction flask strongly in a sand bath until the intensive evolution of gas begins, after which remove the burner. Watch the temperature of the cooling mixture. What gathers in the U-tube Write the equation of the reaction. 

Fig. 81. Fill two-neck bottle 1 up to one-fourth of its volume with a granulated alkali (IV/ten working with an alkali, wear eye protection Handle the alkali only with pincers ) Pour a concentrated ammonia solution into dropping funnel 2. Pour vaseline or paraffin oil (a bubble counter) into wash bottle 3. Put a granulated alkali into drying column 4. What substances should be used for drying ammonia Fasten a dry bottle over gas-discharge tube 6. When you have assembled the apparatus, put solid carbon dioxide ( dry ice ) into...

Heat flask 1 with the flame of a gas burner through an asbestos gauze and estimate the rate of gas evolution according to the number of bubbles in wash bottle 2. When a uniform stream of gas is established, carefully wear eye protection heat the bottom part of vessel 3 with the open flame of a burner. Do not let the products clog the gas-discharge tube. The amount of the aluminium chloride condensing in the upper part of the apparatus should be insignificant.

Personal eye wash Are supplementary stations that support plumbed units with immediate flushing fluid (i.e., a squeeze bottle). 

No one can predict when and where a chemical accident will occur. That s why you and your coworkers you should be familiar with the location and operation of emergency eye wash facilities and safety showers. These can include eyewash fountains, drench showers, hand-held drench hoses and emergency bottles. Very simply, they all flush affected areas of your body with water. 

Check water delivery Ask your employer how much water your eye wash stations deliver. Eye washes should supply 0.4 gallons per minute of water for at least 15 minutes. Safety showers should supply 20 gallons per minute for at least 15 minutes. Note Many portable eye wash stations have a capacity of 5 to 10 gallons for a maximum usefulness of 5 minutes. Squeeze bottles and other plastic containers have even lower water capacities. These eye washes are meant to be supplementary to eye wash stations or showers that provide 15 minutes of flushing. 

Eye washes and safety showers should be inspected according to manufacturer instructions. Squeeze bottles also require frequent testing, refilling, and maintenance since they lose water to evaporation, become contaminated, and are easily misplaced. 

Concerning the laboratories that checklist were applied, some showers and eye wash stations contained obstacles that prevents their use. Eye wash stations should have appropriate access and should be flushed weekly to prevent bacterial build up and to check for water quality. Some storage cabinets had heavy bottles on the upper selves and not all laboratories contained extinguishers. It is important to maintain heavy glass bottles (which may contain hazardous liquids) below eye level to avoid spills. 

Figure 6.1 The tray set-up. The peel tray Is always set up in a standard fashion with well marked bottles. 3" x 3" cotton gauzes and cotton-tipped applicators are available. The eye wash solution is always close at hand. The four bottles of the Progressive Peel are clearly labeled. (The progressive preel ProPeeP, Vivant Pharmaceuticals, Inc. Miami, Ft)...

Fill exactly to the calibration mark using a wash bottle or eye dropper. 

Cleanliness comes very close to godliness in the laboratory. A worker always washes hands before eating or smoking, and many times in between. One thoughtful laboratory operator placed bottles of liquid skin cleanser and hand lotion next to all sinks. Apart from personal cleanliness, there are other important forms of protection for the worker. Most notable among these is eye protection. 

DCC is a waxy solid that is often difficult to remove from a bottle. Its vapors are extremely hazardous to inhalation and to the eyes. It should always be handled in a fume hood. The isourea by-product of a DCC-initiated reaction, dicyclohexyl urea (DCU) (Figure 3.5), is also water-insoluble and must be removed by organic solvent washing. For synthesis of peptides or affinity supports on insoluble matrices this is not a problem, because washing of the support material can be done without disturbing the conjugate coupled to the support. For solution phase chemistry, however, reaction products must be removed by solvent washings, precipitations, or recrystallizations. 

Because of the hazardous nature of anhydrous hydrogen fluoride, adequate precautions should be taken to protect the head, eyes, and skin. Use of rubber gloves, an apron, and a plastic face mask is strongly recommended. All operations should be carried out in a hood. After completion of the reaction, all equipment should be washed with liberal quantities of water. A bottle containing magnesium oxide paste in glycerin should be available... 

Wear nitrile rubber gloves, eye protection, self-contained respirator, and laboratory coat (after each wearing, launder clothing separately). Scoop up and place in large wide-mouth bottle with stopper. Save for recovery or disposal. Wash site with soap solution.6...
