Cutting and grinding is considered “hot work”, therefore:

only cut when there are co-workers on the scene

never cut in the vicinity of flammable materials or in areas without proper ventilation

cutting and grinding is not considered hot work

it is only safe to cut certain pipe materials

that some saws do not require an inspection before use

many newer saws do not require preventative maintenance

they share some common hazards and the requirement for safety precautions

one type of blade cuts all materials

Generally speaking, the more teeth per inch on the blade:

the easier it is to cut thick material

the cleaner the cut

the more jagged the cut

the faster the cut will be performed

If your inspection of a power saw indicates that it is damaged or needs servicing:

only use it if you can’t find another suitable replacement tool

put a tag on it indicating it should not be used, so that others will not pick it up and use it

put it back where you found it

use it, but be careful when you turn it on

The first step when selecting the most appropriate cutting tool is:

to determine what saw and blade will provide the proper result once the cut is complete

to determine how many people are needed to complete the cut

to determine if a supervisor is needed to watch the procedure

to determine how quickly the job needs to be done

If the blade of a street saw stops or stalls during the cut:

speed up

raise the blade above the surface, turn the saw off and check the blade

keep cutting, but position a co-worker at an angle to monitor/watch the blade

slow down

When using a street saw, calculate the length and depth of the cut to determine the manufacturer’s recommendation for horsepower or type of machine and which saw blade is necessary because:

it will allow you to start the cut with the blade on the ground

it will allow you to avoid using water to keep the dust down

it will allow you to run the saw at top speed even if it stalls

forcing a saw that is not big enough for the job, can cause a “kick back”
