• Use on-tool water suppression when cutting, drilling, or grinding masonry or concrete.
• Check the water supply is connected and flowing before starting any dusty task.
• Dampen haul roads and stockpiles regularly in dry weather to control dust.
• Combine water suppression with on-tool extraction for maximum dust control.
• Monitor water levels and refill tanks before they run dry during operations.
• Manage runoff water to prevent silt entering drains or watercourses.
• Position misting sprays upwind of demolition and earthworks activities.
• Maintain water suppression equipment and replace blocked or damaged nozzles.
• Wear RPE as additional protection when dust generation is heavy.
• Record dust control measures used in the task risk assessment.

• DON'T cut concrete, stone, or block without water suppression or extraction.
• DON'T start cutting if the water supply is disconnected or empty.
• DON'T rely on water suppression alone if it visibly fails to control dust.
• DON'T allow slurry runoff to enter surface water drains or watercourses.
• DON'T create excessive standing water that causes slip hazards on site.
• DON'T use water suppression as a reason to avoid wearing RPE when needed.
• DON'T leave misting systems running unattended in freezing conditions.
• DON'T ignore blocked nozzles or reduced water flow during cutting operations.
• DON'T dry sweep slurry residue; use wet vacuum or damp methods instead.
• DON'T assume dampening material once is enough for prolonged cutting tasks.
