- Some of the dust produced by sawing, sanding, drilling and other building work contains chemicals
known to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
- Lead from lead-based paints,
- Crystalline silica from bricks and cement and other masonry products,
- Arsenic and chromium from chemically treated wood.
Your risk from this hazard varies with the frequency at which you perform this type of work. To reduce your
exposure to these chemicals: Work in a well-ventilated area. Work only with approved safety equipment, such
as dust masks that are specially designed to filter out particles of microscopic size.
3.4 Specific safety rules
Sawing method
- Keep your hands away from cutting area and saw blade. Hold the auxiliary handle or the motor
housing with your second hand. If both hands hold the saw, they cannot be injured by the saw blade.
Fig. 3: Incorrect sawing vs. correct sawing
- Do not reach underneath the workpiece. Below the workpiece, the guard cannot protect you from the saw
blade.
- Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth height should be
visible below the workpiece.
- Never hold the workpiece in your hands or across your leg while you are cutting it. Secure the
workpiece on a stable support. It is important to secure the workpiece safely. This minimizes the risk of
body contact, jamming of the saw blade or loss of control over the machine.
- Hold the machine by the insulated grip surfaces when you perform work that involves a risk of the
tool hitting hidden power lines. Contact with a live line also energizes the metallic parts of the machine,
causing an electric shock.
- Always use a fence or straight edge guide for ripping. This improves the cutting accuracy and reduces
the possibility of the saw blade jamming.
- Always use saw blades of the correct size and with a suitable arbor hole (e.g. diamond-shaped or
round). Saw blades that do not match the mounting parts of the saw will run out of true, resulting in a loss of
control.
