What safety precaution must you take before installing or changing a drill bit of an
electric drill?
Remove or disconnect the drill from the power source
What do you do before drilling in metal or other hard surfaces
Use a center punch to mark the exact center of the hole to be drilled
What minimum personal protective equipment (PPE) shall be used for all jobs using a bench grinder?
Eye and face protection
How fast should an electric saw blade be spinning before it contacts the material to

List four safety precautions when dealing with pneumatic tools?
1)Inspect the air hose for cracks or other defects. If you identify defects, make repairs, or replace the hose before using
(2)Before connecting the air hose to the air outlet fitting, open the control valve momentarily. Then connect the hose to the fitting and open the valve again momentarily—this ensures the hose is clear of water and other foreign material
(3)Stop the flow of air to a pneumatic tool by closing the control valve at the compressed air outlet before connecting, disconnecting, adjusting, replacing, or repairing a pneumatic tool
(4)When using sockets, make sure they are designed specifically for pneumatic tools (impact sockets). Non-pneumatic accessories cannot withstand the stresses of pneumatic equipment and can result in damaged equipment and injury to personnel
How many pounds per square inch (psi) are used for safe efficient operation of a pneumatic tool?
90 psi.
What ensures the socket or attachment does not fly off an impact wrench?
Spring-loaded ball bearing or socket lock
What does the torque regulator do for a pneumatic impact wrench?
Reduces the possibility of shearing or damaging threads when installing nuts and bolts
Familiarity of what two things are prerequisites for safe operation of lifting devices?
The manual and equipment to be used.
What will be worn if there is a potential for injury from falling objects or moving equipment?
Protective helmets and safety-toed boots
What are four items that can be used in conjunction with wire-rope slings when lifting munitions?(think equipment)
1)Forklift.(2)Jammer (bomb lift truck).(3)Over-head hoist.(4)Crane
Where can general guidance be found for safe operating procedures using lifting devices?
DAFMAN 91-203 and/or the specific manual for the lifting device
What information do the multimeter’s annunciators display
The polarity, the condition of the meter’s battery, whether you are in manual or auto-range, and
negative annunciator for the bar graph.
What are the two modes of operation for a Fluke 8025-series multimeter?
