Disinfecting

The company shall provide each respirator user with a respirator that is clean, sanitary, and in good working order. The company must ensure that respirators are cleaned and disinfected nsing the standard operating procedure (SOP) under these conditions  

Respirators issued for the exclusive use of an employee shall be cleaned and disinfected as often as necessary to be maintained in a sanitary condition. 

Respirators issued to more than one employee must be cleaned and disinfected before being worn by different individuals. 

Respirators maintained for emergency use shall be cleaned and disinfected after each use.

Disinfeetion. Chlorine, as gaseous chlorine or as the h5rpochlorite ion, is widely used as a disinfectant. However, its use in some cases can lead to the formation of toxic organic chlorides, and the discharge of excess chlorine can be harmful. Ozone as an alternative disinfectant leads to products that have a lower toxic potential. Treatment is enhanced by ultraviolet light. Indeed, disinfection can be achieved by ultravifflet light on its own. 

Condy s fluid A disinfectant solution of calcium and potassium permanganates. 

Htrichlorophenol, C6H3CI3O. Colourless crysfa)]inesubslance,m.p. 68°C. Usedmedicin-ally as an antiseptic and disinfectant. 

The aqueous solution of sodium chlorate(I) is an important liquid bleach and disinfectant. It is produced commercially by the electrolysis of cold aqueous sodium chloride, the anode and cathode products being mixed. The sodium chloride remaining in the solution does not usually matter. There is evidence to suggest that iodic(I) acid has some basic character... 

Minor—wash thoroughly with soap or disinfectant and water until absolutely clean. Apply sterile dressing. 

If the third substance dissolves in both liquids (and the solubility in each of the liquids is of the same order), the mutual solubility of the liquids will be increased and an upper C.S.T. will be lowered, as is the case when succinic acid or sodium oleate is added to the phenol - water system. A 0 083 molar solution of sodium oleate lowers the C.S.T. by 56 -7° this large effect has been applied industrially in the preparation of the disinfectant sold under the name of Lysol. Mixtures of tar acids (phenol cresols) do not mix completely with water at the ordinary temperature, but the addition of a small amount of soap ( = sodium oleate) lowers the miscibility temperature so that Lysol exists as a clear liquid at the ordinary temperature. 

Acids on the skin. Wash immediately and thoroughly with a liberal quantity of water, then with saturated sodium bicarbonate solution, and finally with water. For a serious acid bum, follow this by applying a disinfectant, drying the skin and covering with acriflavine jelly. 

If the cut is Only a minor one, allow it to bleed for a few seconds, see that no glass remains, apply a disinfectant (rectified spirit, Dettol, 1 per cent aqueous chloramine-T solution, or sulpha-pyridine powder) and bandage. 

For serious cuts, send for a doctor at once meanwhile wash with a disinfectant and endeavour to check bleeding by applying pressure immediately above the cut. Continuous pressure should not be maintained for more than five minutes. 

Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. Further use is in the manufacture of chlorates, chloroform, carbon tetrachloride, and in the extraction of bromine. 

Amines also react with epoxides at the less substituted carbon atom. As a slightly more testing problem, suggest a synthesis of the alcohol (TM 165) whose derivatives are used in disinfectants ("phemeiide" etc.).
