REFERENCES
A
The rotation of the chuck
and bit is an entanglement
hazard. Debris from the
drilling can be thrown
towards the operator.
Install a shield—interlocked if possible—
to prevent chuck access and protect the
operator from debris.
Sec. 25 (1)(a),(d) OHSA
Sec. 25 (1)(b),(b.1) OHSA
Sec. 25 (2)(a),(d) OHSA
Sec. 25 (2)(h) OHSA
Sec. 24, 26, 83, Reg. 851
B
If the workpiece jams on the
drill bit, it can spin and strike
the operator.
Ensure workpieces are properly
clamped/secured prior to starting to
drill.
Sec. 25 (1)(a), (d) OHSA
Sec. 25 (2)(a) OHSA
Sec. 24, and 26 Reg. 851
C
A mortiser can be top heavy
and can be prone to tipping.
Ensure the mortiser is secured to the
floor/tabletop to prevent tipping.
Sec. 25 (2)(a) OHSA
Sec. 46(b), Reg. 851
D
Damaged electrical
connections or components
can create a risk of shock or
inhibit safe operation.
Regularly inspect the electrical
connections and plug to confirm they
are free from damage. When repairs
are needed, following lockout tagout
procedures.
Sec. 25 (1)(b) OHSA
E
Setting up the mortiser
involves handling sharp
drill and chisel bits, which
can cause cuts or puncture
injuries to the hands.
Use puncture-resistant gloves when
setting up the machine. Handle
components carefully and regularly
inspect drill bits and chisels for damage
or burring.
Sec. 25 (1)(b.1) OHSA
Sec. 84, Reg 851
The chisel point can become
very hot during operation,
particularly during extended
use, creating a burn hazard.
Handling the chisel and bit immediately
after use should be avoided. Allowing
time for cooling may also help reduce
the risk of fire when working with wood.
