Q

Describe your safety considerations

a) Prior to using and
b) During use of the Stanley hydraulic CO25 Cut Off Saw

A

Give tool a good visual prior to using

Check saw blade is correct size, type and condition for task

Check security of centre nut

Check guard is in correct position for task

Give blade a ‘ring test’ to check blade quality

Run tool for at least 30 secs prior to use

Ensure legs and feet are well clear of rotating blade

Be aware of the positioning of the hydraulic hose Ensure body positioning is correct

Control water flow and water hose if not in use

Maintain safety zone to the front and rear of tool operations

Ensure centre nut spacers are kept clear of materials etc Correct PPE

The tool should be run for approx 30 secs after use in order to clear any debris/slurry.

Q

List 3 of your operational considerations prior to using the DS 11 saw in confined space

A

Give tool a good visual prior to using

Ensure chain is fitted the right way and is adjusted

Must maintain sufficient water supply

Consider the water run off in terms of casualty and building stability

Have tools available to maintain tool

Wear correct PPE and protective aprons Improve working conditions

Consider projection of chain on other side

Consider the sequence of cuts, (bottom cut not last)

Consider body positioning/ manual handling Run tool for at least 30 secs prior to use

Consider the use of bevels(but not too severe)

Ensure bottom cut is not through a horizontal rebar

The tool should be run for approx 30 secs after use in order to clear any slurry.

Q

Filters on the Delsar are intended to add clarity to the sound in the earphones and ideally should be set at what point during a Delsar sweep.

A

The filters should be set at the beginning of the sweep in an ideal situation

This is what we would hope to find at an operational incident, this will allow an equal level of noise travel as the operator progresses across the pile.
