Lesson 4: OSHA Table 1 – Control Methods by Task

Title: OSHA Table 1 – Control Methods by Task
Type: Lesson

What Is Table 1?

OSHA Table 1 is a list of 18 common construction tasks that generate respirable crystalline silica — and for each task, it lists specific control methods that must be used to reduce exposure.

If your job follows Table 1 controls correctly: ✅ You do not need to conduct exposure monitoring or testing.

How Table 1 Works

Table 1 provides:

1. Task name (e.g., cutting, grinding, drilling)

2. Tool type (e.g., handheld saw, walk-behind saw)

3. Control methods required (e.g., wet cutting, vacuum dust collection)

4. Respiratory protection requirements (depending on task duration and environment)

Example: Using a Handheld Power Saw

Key Control Methods in Table 1

• Water delivery (wet cutting): Minimizes airborne dust by keeping the blade and material wet

• HEPA vacuum systems: Capture dust at the point of origin

• Shroud attachments: Used with grinders and drills to contain dust

• Enclosures or isolation: Barriers or enclosures keep others from being exposed

Table 1 Covers These Tasks:

• Handheld power saws

• Walk-behind saws

• Drivable saws

• Drills (handheld & stand-mounted)

• Jackhammers and chipping tools

• Milling machines

• Grinding

• Tuckpointing

• Crushing machines

• Heavy equipment (cutting, trenching, or grading)

You must follow all specified controls and wear required PPE for full compliance.

When NOT Using Table 1

If your task is not listed or you don’t follow Table 1 controls:

• You must measure worker exposure levels

• Conduct air monitoring

• Possibly implement a written exposure control plan

Key Point

Table 1 simplifies silica safety by telling you exactly what to do. If your job is on the list, follow the control method and PPE requirements to stay safe and OSHA-compliant.
