4. Woodworking Machines

Question 1

What are the 7 common types of safety hazard associated with production wood working?

Answer 1

• Machine Hazards (POO, rotary/reciprocating, in-running nip/pinch points)
• Kickbacks
• Flying Chips/Material
• Tool Projection
• Fire and Explosion
• Electrical
• Musculoskeletal

Question 2

What are the 4 common types of health hazard associated with production wood working?

Answer 2

• Noise
• Vibration
• Wood Dust Inhalation
• Chemical Exposure

Question 3

List controls to reduce kickback on a tablesaw.

Answer 3

• Use anti-kickback fingers and a splitter/spreader/riving knife
• Keep operator to the side of the feeding operation
• Use heavy padded PPE (apron etc.) to minimize impact injuries.
• Keep sawblades sharp and in good condition.

Question 4

What should be used to reduce risks of crosscutting on a tablesaw?

Answer 4

A mitre tool should be used to stabilize the wood instead of a rip fence.

Question 5

What can be used to push narrow wood through a saw?

Answer 5

A push stick.

Question 6

Contrast planing and jointing.

Answer 6

A planer auto-feeds wood, cutting the top surface, making it parallel to the bottom surface. It can process multiple boards to a uniform thickness. The surfaces may not be perfectly flat/straight.

A jointer is manually fed, cutting the bottom surface of wood, making it perfectly straight. The top/bottom may not be perfectly parallel and multiple boards may not be identical thickness.

Question 7

What are the 5 most common, general hazards associated with planing/jointing?

Answer 7

POO contact with cutting head.

In-running roll, clothes/hair/hands caught and pulled into feed mechanism.

Kickbacks

Flying debris (chips, splinters, dust)

Vibration (physical harm and noise)

Question 8

What are the three most critical hazards associated with sanding of wood?

Answer 8

POO - contact with disc/drum/sander

In-running nip points - clothing, hands, or hair may be caught and pulled in

Flying chips - Wood splinted and chips may be thrown

Question 9

What guards are commonly used for:
1, belt sanders
2, Disc sanders
3, Wood dust from sanders

Answer 9

1, a fixed guard covering the unused portion of the belt.

2, An auto-adjustable guard hinged around the outside of the disc.

3, An LEV system.

Question 10

What are the four most common POO hazards associated with wood drills?

Answer 10

Unsecured wood may spin and strike operators.

Entanglement of clothing, jewelry, hair.

Cut from drill bit.

Flying debris/wood from work.

Question 11

What hazards should be considered with any handheld power tools?

Answer 11

1, cuts or abrasions from POO contact

2, in-running nip points - entrapment/entanglement

3, Flying debris

4, Vibration & noise

5, Electrocution (ensure double insulation and GFCI)

Question 12

List 5 basic woodworking processes.

Answer 12

Sawing
Planing and jointing
Turning and shaping
Sanding
Drilling
