Health & Safety:

All dusts are respiratory irritants and therefore inhalation of the dust should be avoided. Particulate masks are highly recommended. Fine powders are hygroscopic and some may irritate eyes or skin. Some people are more sensitive than others. Employees should change at work, coveralls should have long sleeves. Always wash powder off skin, never use an air line, as pressured air may force powder particles into the skin, causing irritation. Encourage employees to shower before going home. It is mandatory for employees to wash their hands before eating, smoking or going to the washroom. If skin contact occurs, wash with soap and water. Some powders emit low volumes of volatile organic compounds during the cure cycle in the oven. Make sure your oven has the capabilities of proper exhaustion. Maintain proper airflow, as specified by the equipment manufacturer, into the booth to prevent powder migration. Like any fine organic particles, powder can be ignited by electrical spark or flame. Dust collection equipment should be provided with adequate explosion venting and all equipment grounded to avoid static build-up. Consult the Material Safety Data Sheet for your specific powder before handling.

Proper Storage and Handling:
|
|
|
|
Powder must be kept dry at all times. Check air lines to ensure that the supply is clean and dry prior to connecting to feed hopper. Powder should be stored at 26°C (80°F) or less for optimum shelf life. Store in sealed containers when not in use. To fill the hopper, remove the bag of powder from the box and, before cutting the tie, roll gently on the floor to relieve any settling that may have occurred. Then vacuum off the outside of the bag before cutting the tie and dumping into the hopper. This will ensure that the powder will fluidize well and not introduce contaminants into the powder system. Disposal Consult your local dump site for regional regulations regarding disposal of old or contaminated powder. Most areas take the powder just as it was shipped to you. Some require double bagging, some want powder melted into a block.
