well about an hour ago i just sanitized my pool with Aqua Chem's Small Pool Sanitizer (it controlls algea and kills bacteria) it provided clorine to my pool and now my pool is at the correct clorine level
my question is can i shock my pool right now after i have just sanitized it with that stuff. (the Shock is a 4 in one pool shock that came with my Small Pool Sanitizer)?
will it hurt my vinyl pool?
will it cause a chemical reaction?

Food importers want the food to be free of pathogens, toxins and pollutants.
KARACHI: A three-day food safety training course was held at the University of Karachi, the objective of the course was to train Pakistanis about food safety and quality control.
The course aimed to enable them to provide safer, more wholesome food to the people of Pakistan as well as to permit Pakistani food products to be exported to high value international markets in compliance with World Trade Organisation (WTO) regulations and international trade requirements.
The training course titled ‘Good Manufacturing Practices and Sanitation Standard Operating Procedures and Hazard Analysis Critical Control Point (HACCP)’, and it was held, from August 6 to 8, at Latif Ebrahim Jamal Auditorium and was jointly organised by University of Karachi and Pakistan Society for Microbiology.
The programme not only attracted scientists, academicians, students and supervisors from government agencies such as Pakistan Council of Scientific and Industrial Research, Pakistan Agricultural Research Council but also several food quality control and safety experts from various companies and organisations. they all had the same concern – Pakistan lags behind in good manufacturing practices for food. and due to this inability to meet WTO requirements dozens of our trade consignments are rejected at different ports, this has caused huge economic losses.
Due to global needs for food supply, new food safety challenges have emerged, and importing countries are heavily concerned about the safety of food, especially seafood. they want the food to be free of serious pathogens, pesticides, drug residues, food additives, environmental toxins and organic pollutants explained the Pro-Vice Chancellor of University of Karachi, Prof. Dr Shahana Urooj Kazmi, at the inaugural session.
She said that ensuring food safety at all levels is very important for human, animal and plant health because food-borne contaminants have proved to be a cause of illness. “The food manufacturers should have knowledge about good manufacturing and agricultural practices, starting from the farm to the factory, meal table and export houses” said Kazmi.
While focusing on Pakistan, Kazmi warned against excessive use of pesticides in crop fields and the intentional mixing of toxic chemicals such as melamine in baby milk and carcinogenic drugs in animal feed. In regards to quality control she said that we need to improve on our critical control point monitoring systems. “They are not fully developed in Pakistan, we therefore face problems in implementing sanitary guidelines to meet WTO requirements” she said. She also emphasised the need for creating general awareness and organising training courses for food scientists. Washington State University’s Prof. Dr Barbara Rasco was the instructor for this course, she highlighted the international standards required to ensure that food was processed under standard sanitary conditions.
“Hazard Analysis and Critical Control Points is based on establishing critical control limits, monitoring procedures, taking corrective measures, verification and record keeping. all this must be implemented properly paired with good manufacturing practices,” she said.
After the inaugural session many interactive scientific sessions were held. These topics were discussed by Prof. Gleyn and Prof. Barbara, assisted by University of Karachi’s Nain Tara from and Ambreen Ansari.
This capacity building programme for academia and industry representatives has been developed under the Trilateral Commission’s Trade Corridors Working Group consisting of Pakistan, USA and USDA – Foreign Agriculture Service. the funding for the training courses has been provided by the US Department of Agriculture’s Foreign Agricultural Service. the companies which attended included National Foods, Young’s Food, Agro Processors and Atmospheric Gases, English Biscuit Mfrs, Domino’s Pizza-Pakistan, Hilal Confectionary, the Bhombal Group and PIA Flight Kitchen.

Kanoria Chemicals and Industries ltd plans to use the proceeds from the divestment of its chloro-chemicals division for expansion of the speciality and fine-chemicals business.
Kolkata, July 2:
Kanoria Chemicals and Industries ltd plans to use the proceeds from the divestment of its chloro-chemicals division for expansion of the speciality and fine-chemicals business. also planned is an entry into solar energy, preferably in Rajasthan.
Kolkata-based Kanoria sold its flagship chloro-chemicals business to Aditya Birla Chemicals (India) ltd for Rs 830 crore in April, and is now left with the fine-chemicals business through its formaldehyde plant in Visakhapatnam. the company says it will now focus on production of a wider range of fine and speciality chemicals from Vizag.
“Of the Rs 830 crore that we got from the divestment, close to Rs 330 crore was spent on repaying the debt, Rs 32 crore went towards dividend payment and Rs 100 crore for tax payment. We are now left with approximately Rs 370 crore in cash, and this will be invested in 4-5 new businesses,” the Chairman and Managing Director, Mr R.V. Kanoria, told newspersons on the sidelines of the Federation of Indian Chambers of Commerce and Industry’s national executive committee meeting here on Saturday.
According to him, the company also plans foray into the renewable energy sector, preferably solar.
“We are interested in renewable sector such as solar. We will take a long-term bet on it, but the initial investment will not be too high. Rajasthan will be a preferred destination for such foray,” he said. he refused to divulge further details of the project.

Storage and Shipping are two very different things. I would neverconsider 135 F to meet the definition of "cool" for storage ofchemicals. Our company considers 2 to 30 C to be Room Temp and I findthat rather broad. I have never seen an actual definition of "cool & dry" in terms ofdegrees or humidity as the words are used on an MSDS. this would begreat info to have but in my experience with MSDS’s, I often find themlacking on specifics and purposely vague in their wording. In general,if I am sweating in the storage room, it is too hot for long termchemical storage. We try to maintain our spaces at 72F with no morethan 65% RH. We have ICT Tests that are very sensitive to temp and humidity so theconditions need to be met in warehousing as well. because our productis sensitive, our chemicals are maintained at a "comfortable" temp andhumidity by default. for what it’s worth… J Janeen Lapierre, CHOR&D Scientist II Alere10 Southgate RoadScarborough, ME 04074 [log in to unmask] —–Original Message—–From: SAFETY [mailto:[log in to unmask]] on Behalf Of Dan KallinSent: Saturday, April 02, 2011 7:51 AMTo: [log in to unmask]Subject: re: [SAFETY] Chemical Storage Conditions Hi Ray, My point was that unless it is marked to keep refrigerated or withspecific storage parameters, materials should be able to safelywithstand storage temperatures to 130 F. I suspect it was shipped toyour warehouse after all. the moisture is a bit tougher, if you havemoisture reactive chemicals, they should also be packaged to preventmoisture intrusion for safe storage. Some exposure to rain or highhumidity would be considered a normal condition of transport. Floodingwould not. if your concern is moisture sensitive materials, such aspaper, you may want to get guidance from the manufacturer to ensurequality. the restrictions for quality purposes will likely be morerigid than safety purposes but they will also be spelled out morespecifically than "cool and dry". if in a manufacturing environment, getsome input from the quality assurance folks.
