Question 1

Which OSHA standard primarily governs lockout/tagout procedures in a carpentry workshop?

Accepted Answer

29 CFR 1910.147

Answer

29 CFR 1910.147 (Control of Hazardous Energy) establishes lockout/tagout requirements to prevent unexpected energization of machinery during service.

Question 2

When setting up a router table fence, the infeed and outfeed fence sections should be:

Accepted Answer

Both sections set flush with each other and tangent to the bit's cutting arc

Answer

For most router table operations both fence faces are coplanar and tangent to the bit's outermost cutting radius, providing consistent support throughout the cut.

Question 3

A table saw's blade guard and splitter (riving knife) primarily protect against:

Accepted Answer

Kickback and blade contact

Answer

The splitter keeps the kerf open to prevent the wood from pinching the blade and causing kickback, while the guard covers the exposed blade teeth.

Question 4

What does a torque specification on a fastener indicate for tool maintenance purposes?

Accepted Answer

The rotational force required to achieve proper clamping without stripping

Answer

Torque specifications define the clamping force needed so that fasteners are tight enough to function properly without being over-tightened and stripped.

Question 5

When grinding a chisel bevel on a bench grinder, overheating the steel is dangerous because it:

Accepted Answer

Draws the temper, permanently softening the cutting edge

Answer

Excessive heat from grinding destroys the heat treatment (temper) of the steel, leaving a soft edge that dulls rapidly and cannot hold a keen edge.
