Personal Protection Equipment, or PPE), which will be posted at each machine. All
users must comply with the PPE standards for each powertool at all times.
5. Dust collection must be used when power tools are in operation and where
provided. You are responsible for cleaning out dust collection systems after you're
finished working, as a part of proper clean up procedures (see below), especially if
the dust collection is filled. *Note--the new Grizzly dust collection portable unit
operates on a 220V outlet only. There is a 220 outlet installed by the planer for use
with the bandsaws, radial arm saw, planar, and new spindle sander. DO NOT use
in any other outlet.
6. All safety guards must be in place and cannot be removed from tools, machines,
or any other equipment in the woodshop. All guards must be in the "down" position
(completely covering the blade) when finished, including the bandsaws.
7. Tools must never be left running unattended. The user must wait until the tool
has been turned off and all motion has stopped before leaving the tool.
8. If a user chooses to bring his or her own personal tools to work on a project, the
user will be solely responsible for understanding and abiding by the proper
operation of those tools, and does so at his or her own risk of loss or damage.
9. If a power tool is defective -or- damaged, this must be reported to Krista Hoefle
and the Department of Art immediately. The defective tool will be tagged as being
“out of order” and will be repaired or replaced as soon as (or if) possible.

and only on large sheets of butcher paper or cardboard. Do not spray paint any
project on bare concrete or grass in the courtyard.
First Aid and Emergency Procedures
1. Individual instructors will provide appropriate safety information and protocols
for courses including material handling, disposal and storage methods, and other
pertinant information. For more information regarding hazards and emergencies,
see the Saint Mary's College Hazard Emergency Plan:
http://www3.saintmarys.edu/emergency-response-plan
2. Be familiar with the location and use of the following safety devices:
a. Emergency Phone - in the shop area by the Radial Arm Saw.
b. Eye Wash Station - by double sinks adjacent to the plaster mixing area.
c. First Aid Kit - by the tool crib adjacent to the Panel Saw.
3. In case of an incident or emergency, the main switch for the power tools must be
turned off immediately. This large red switch is located on the east wall as you
enter the Design area from the shop.
Material Safety Data Sheets (MSDS)
1. MSDS will tell you of any special procedures that may be required for the safe
handling of a specific substance. MSDS Sheets for the shop, Sculpture and
Flammables Cabinet (located in Design) are located in a yellow binder on the
door of the tool crib.
2. Faculty and students are required to add MSDS sheets to this binder every
time they bring a new material into the shop area. Remember, new materials
must be pre-approved prior to use.
3. MSDS are a valuable source of information when you have questions or
concerns about any chemical or material that you work with. It is a good idea to
consult the MSDS for any new chemical or material that is introduced into your
work routine, this is a quick and easy way to familiarize yourself to any hazards or
precautions that you should take when working with a new substance.
A failure to comply with these guidelines may result in the user being expelled
from the shop, and his or her privileges to use the shop in the future may be
revoked.
