1. 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
2. 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.
3. What minimum personal protective equipment shall be
used for all jobs using a bench grinder?: Eye and face
protection.
4. How fast should an electric saw blade be spinning before it
contacts the material to be cut?: At full speed.
5. 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 momen- tarily—this ensures the hose is clear of

(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.
6. How many psi are used for safe efficient operation of a
pneumatic tool?: 90 psi.
7. What ensures the socket or attachment does not fly off an
impact wrench?-
: Spring-loaded ball bearing or socket lock.
8. What does the torque regulator do for a pneumatic impact
wrench?: Re- duces the possibility of shearing or damaging threads
when installing nuts and bolts.
, 9. Familiarity of what two things are prerequisites for safe
operation of lifting devices?
2: The manual and equipment to be used
10.What will be worn if there is a potential for injury from
falling objects or moving equipment?: Protective helmets and
safety-toed boots.
11.What are four items that can be used in conjunction with
wire-rope slings when lifting munitions: (1) Forklift.
(2) Jammer (bomb lift truck). (3) Over-head hoist.
(4) Crane.
12.Where can general guidance be found for safe operating
procedures using lifting devices?: AFI 91-203 and/or the specific
manual for the lifting device.
