WorkSafe WA to keep watch on coating practices

WorkSafe WA will keep a close eye on businesses conducting powder-coating activities after a recent survey of industry highlighted a lack of awareness of the dangers associated with the process. Powder-coating is a process by which powder is applied electrostatically to an item before being heat cured to form a skin-like casing.

WorkSafe’s Director Manufacturing, Transport and Service Industries, Joe Attard, said a targeted inspection of 34 metropolitan and regional businesses found that many were conducting powder-coating activities with limited knowledge of the risks involved and without taking adequate measures to safeguard workers.

“Although there were some very good powder-coating businesses operating in WA,” said Attard, “WorkSafe was concerned that a number of operators were not taking appropriate health and safety measures. The problem seems to be mostly with businesses that had previously contracted out their powder-coating needs to specialist operators.

“But with rising costs, they are now doing the work in house, using staff not adequately trained or equipped to do the work safely. Triglycidyl Isocyanurate (TGIC), for example, is a very hazardous substance that is used in some powders to enhance finish and durability. The compound is known to increase skin and respiratory tract sensitivity, is toxic if inhaled or ingested, can cause serious eye damage and can cause birth defects in the offspring of males exposed to it. Although most major brands have removed TGIC from their powders, it is still found in some powders available in WA.

“It is vital that businesses using these brands are aware of the extra precautions that need to be taken to ensure their workers are not put at risk. Even coatings free of TGIC are potentially dangerous if not handled properly. Other chemicals that are commonly used in the coating process, such as hydrofluoric acid, are extremely dangerous.

“Another risk that needs to be considered is the electrical hazard associated with electrostatic spray painting. For example, by earthing the equipment and the objects being coated, you can ensure maximum coating efficiency and reduce the level of free dust. This will prevent the build-up of static charges capable of igniting the powder-dust clouds.

“Any workplace involved in powder-coating activities needs to have workers trained in the correct use of the products and relevant health and safety measures in place, including protective equipment and clothing, and specific first-aid procedures. Without these safeguards, workers are at risk of serious health problems.”

WorkSafe will continue to monitor businesses to ensure they comply with the necessary occupational health and safety requirements.
