▍What is WERCSmart REGISTRATION?

WERCSmart is the abbreviation of World Environmental Regulatory Compliance Standard.

WERCSmart is a product registration database company developed by a US company called The Wercs. It aims to provide a supervision platform of product safety for supermarkets in US and Canada, and make product purchasing easier. In the processes of selling, transporting, storing and disposing products among retailers and registered recipients, products will face increasingly complicated challenges from federal, states or local regulation. Usually, the Safety Data Sheets (SDSs) supplied along with the products do not cover adequate data of which information shows compliance with laws and regulations. While WERCSmart transforms the product data to that conforming to laws and regulations.

▍Scope of registration products

Retailers determine the registration parameters for each supplier. Following categories shall be registered for reference. However, the list below is incomplete, so verification on registration requirement with your buyers is suggested.

◆All Chemical Containing Product

◆OTC Product and Nutritional Supplements

◆Personal Care Products

◆Battery-Driven Products

Perfluorohexane: Perfluorohexane has been listed in the PFAS inventory of the OECD and the US EPA. Therefore, the use of perfluorohexane as a fire extinguishing agent should comply with local laws and regulations and communicate with environmental regulatory agencies. Since the products of perfluorohexane in thermal decomposition are greenhouse gases, it is not suitable for long-term, large-dose, continuous spraying. It is recommended to use it in combination with a water spray system.
Trifluoromethane: Trifluoromethane agents are only produced by a few manufacturers, and there are no specific national standards regulating this type of fire extinguishing agent. The maintenance cost is high, so its use is not recommended.
Hexafluoropropane: This extinguishing agent is prone to damage devices or equipment during use, and its Global Warming Potential (GWP) is relatively high. Therefore, hexafluoropropane can only be used as a transitional fire extinguishing agent.
Heptafluoropropane: Due to the greenhouse effect, it is gradually being restricted by various countries and will face elimination. Currently, heptafluoropropane agents have been discontinued, which will lead to problems in refilling existing heptafluoropropane systems during maintenance. Therefore, its use is not recommended.
Inert Gas: Including IG 01, IG 100, IG 55, IG 541, among which IG 541 is more widely used and is internationally recognized as a green and environmentally friendly fire extinguishing agent. However, it has the disadvantages of high construction cost, high demand for gas cylinders, and large space occupation.
