This section gives any special precautions to be taken in storage and handling such as avoiding reaction hazards with oxidizing agents, reducing agents, acids, etc, and smoking or other sources of ignition if the product is flammable. Our sample sheet says Bowl Descaler Pro should be stored away from bleaches, ammonia, and strongly alkaline materials. Precautions involving temperature, humidity, ventilation, exposure to sunlight, and other environmental variables may also be given. This section may also list other general precautions that have not previously been mentioned.
Our sample sheet also uses this final section to tell us who prepared the MSDS and when it was prepared.
