To review the latest developments in application technology, these advancements have been delineated into the various components of a powder spray system including guns, delivery devices (e.g. hoppers, pumps, hoses, etc.), reclaim systems and gun movers. Color change technology and equipment specifically designed for non-traditional substrates is also included. Some really cool developments have emerged, ranging from something simple and perhaps obvious, like an LED light attached to a manual gun body, to sophisticated electrostatic charging systems.

Personal Protection Equipment (PPE) is defined by Wikipedia as “clothing, helmets, goggles, or other garments or equipment designed to protect the wearer’s body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter.” This definition continues to state: “The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present.”
