Silica dust
Read these 5 points to the crew before work, ask the questions, and get signatures. Based on 29 CFR 1926.1153 (Table 1).
Say this
- Cutting, grinding or drilling concrete, block, brick or stone makes silica dust. It causes silicosis and lung cancer.
- Water on the blade or a vacuum shroud, every time.
- Follow Table 1 for the tool. It says when you need a respirator.
- No dry sweeping or compressed air. Wet sweep or HEPA vac.
- A written exposure control plan is required, and a competent person runs it.
Ask the crew
- Where on this site today does "silica dust" matter most?
- What would you do first if it went wrong?
- Who do you tell, and how?

How to give it
Hold it where the work is, at the start of the shift, standing up. Read each point out loud, then point at the real thing on this site: the trench, the ladder, the machine, the cord. Ask the questions and wait for answers; the quiet ones often know the most. Keep it to about 5 minutes so it gets done every day.
Write down anything the crew raises and fix it before the work starts. Everyone signs, including subs and visitors working that shift. Keep the signed sheet with the day's JHA; it's your record that the training happened (29 CFR 1926.1153 (Table 1), and 29 CFR 1926.21(b)(2)).
