and Textile " has updated  the draft Gulf Standard  No. 528/2013  "Liquid Chlorine ". 
The Draft Standard has been prepared by ( United Arab Emirates ). 
  
This standard has been approved as a Gulf Standard  by GSO Board of Directors  in 
its meeting No.(        ),held on      /    /            H ,     /     /              G.

 The following security procedures shall be taken into consideration when handling, 
transporting and storing liquid chlorine:  
 
9.1 Chlorine, in both gaseous and liquid forms, is non-flammable and non -explosive but it 
can facilitate flammability of some materials.  
 
9.2 The volume of liquid chlorine quickly increases as its temperature rises. One pound of 
liquid chlorine gives 4.98 cubic feet of gas.  
 
9.3 Chlorine gas causes sensitivity and  inflammation of the respiratory track in human 
beings in case of inhalation of high concentration of the gas, and may even cause death.  
 
9.4 Liquid chlorine may cause burns if it comes into contact with skin . 
 
9.5 The allowable air con centration of chlorine is 1 ppm.  
 
9.6 In the event of uncontrolled spillage of chlorine, persons in the surrounding area must be 
evacuated as quickly as possible in the wind direction until the chlorine evaporates by 
the blowing wind. Persons in the neighboring area should be informed pa rticularly  those 
located in the direction of the wind.  
 
9.7 Neutralizing chemicals such as (Caustic Soda) may be used to minimize the effect of 
spilled chlorine.  
 
9.8 It is forbidden to spray water on the spilled chlorine as this will increase its rate of 
evaporat ion. 
 
9.9 In case  of fire:  
 
9.9.1 chlorine cylinders shall be quickly moved to a distant area away from fire heat.  
 
9.9.2  If it is not possible to move the cylinders away, they shall be cooled by cold 
water throughout the fire period . 
 
9.9.3 Persons involved shall wear breathing aids thought the period of fire fighting.  
 
 
10. LABELLING  
 
The following information shall be stated clearly and legibly in Arabic or in both Arabic  
And English on liquid chlorine  cylinders  on the label and according to  
Gulf standard mentioned in clause (2. 11) : 
10.1 Name of the product.  
10.2 Name  of manufacturer , the address  and/or his trademark.  Gulf Standard                                                             GSO DS 528/2013

10.10 Shelf - life. 
10.11 Precautions ,Warnings and First aids.  
 
11.     RULES FOR ACCEPTANCE AND REJECTION  
11.1 Each consignment of liquid chlorine cylinders  must be accompanied with a certificate issued 
either from National Standardization Body (NSB) or from any other official body approved by 
NSB s howing that the co nsignment is complying with this gulf standard.  
11.2 The  consignment is considered complying if it the samples (Final sample representing  
The consignment) have passed all the required tests analysis as stated in this Standard.  
11.3 In case one or more sam ples failed any of the tests, a second sample twice the size of the  
First sample shall be withdrawn from the same consignment and be subjected to all the  
 Required tests. Other than that, the consignment shall be considered not complying with
