Toolbox Talk: Silica Dust

Why it matters

Breathing fine silica dust causes silicosis, lung cancer and other diseases. There is no cure, but it is preventable.

Talking points

• Where it comes from: cutting, grinding, drilling, chipping and sweeping concrete, brick, block, stone, mortar and tile.
• Wet methods: use water to keep dust from becoming airborne where the tool allows.
• Dust collection: use tools with a shroud and a vacuum with a HEPA filter.
• Follow the plan: OSHA's Table 1 lists the controls and respirator needs for common tasks.
• Respirators when required: wear the one assigned to you, fit tested, with a clean seal.
• Never use compressed air or dry sweeping to clean dust. Use a HEPA vacuum or wet methods, and wash up before eating.

Ask the crew

1. Which of today's tasks will make dust?
2. What control (water or vacuum) goes with each tool?
3. Who is responsible for checking the controls are working?

Before we start work today: Check that water or dust collection is working on every tool before cutting or grinding starts.
