Check Y N N/A

1 Are the power cords free of frays and damage?

2 Do you know where the emergency stop feature is located? The grinder has an attachment plug and receptacle (plug/socket combination) and so it may be used to disable the machine in the event of an emergency.


4 Is the area around the grinder free of slip/trip hazards?

5 Has the debris/material from previous operations been removed?

6 Are the wheels free of defects? (Faults in the wheels can be very hazardous).

7 Do the wheels move freely without obstruction? Turn the wheel by hand to ensure it doesn’t touch the guard, spark deflectors or tool rests and runs freely.

8 Is the tool rest kept adjusted no greater than a 3mm gap to the grinding wheel, above the centerline of the grinding wheel?

9 Is the material you are grinding suitable for the grinder and wheel being used? Wheels are made only for grinding certain items. Do not grind rough forgings on a small precision grinding wheel.

10 Is the material the correct size for the grinder being used? (Ensure the material is not too big or too small).

11 Is there a water container nearby for cooling of the material being ground?



This procedure is outlined as follows: General Safety Guidelines Equipment Specific Safety Operating Procedure 3.1 General Safety Guidelines Before using the machine, perform the following general safety checks:






• Make sure the cord is kept away from heat, oil, sharp edges or moving parts and does not pose a trip hazard.






1. Before using the Buffer and Belt Sander

Pict

ure

1

a) Put on your PPE. b) Be careful of the pinch point and entanglement hazards between the wheel

and the tool rest (see picture 1). c) Make sure that the wheel is not in contact with the work when you go to

start the grinder. d) Stand to one side, turn the power and allow the motor to reach full speed. e) The grinder has an attachment plug and receptacle (plug/socket

combination) for cord connection, which may be used to disable the machine in the event of an emergency.

2. Using the buffing wheel

Pict

ure

Check Y N N/A

1 Is the area around the kiln free of slip/trip hazards and kept dry? (Do not stand in moisture while operating the kiln).

2 Are flammable/combustible materials (e.g. paper, plastic) removed from the immediate area?


Are the kiln, lid and floor bricks free from large defects/cracks?

4 Is the kiln clean? Remove contaminants if necessary.

5 Is the lid closing properly?

6 Is the lid brace connected securely to the kiln and kiln lid?

7 Is the ware bone dry? (firing damp ware can result in the loss of ware or kiln damage by explosion from rapidly escaping steam).

8 Are you using witness cones? Never fire the kiln without witness cones (even if your kiln is equipped with an automatic controller or kiln sitter) as they virtually eliminate the risk of over-firing by measuring the amount of heat absorbed and the also confirm the proper functioning of the firing and instrumentation. Place them so that they are visible through the peepholes, at an 8° angle from vertical in a cone holder.

9 Is there adequate ventilation?












1. Before using the Kiln

Pi

ctur

e 1

a) Put on your PPE. CAUTION: The kiln produces extreme heat. b) For every firing, place three witness cones (see picture 1) 3" behind each

peephole and on every kiln shelf (these indicate if the kiln is firing evenly and confirms the proper functioning of kiln instrumentation (e.g. kiln sitter).

2. Loading the Kiln

Pict

ure

2

a) Ensure the kiln is off. b) Open the lid (see picture 2). c) Load the kiln (see picture 3) as fully and evenly as possible to ensure even

heat distribution and oxygen circulation. Do not rush loading. d) For bisque firing: pieces may touch one another and some can be stacked. e) For glaze firing: the pieces should not touch each other or have glaze on

the bottom touching the shelf f) Determine firing schedule. g) Prepare to fire-observe caution when firing as the surface becomes very

hot and can result in burns; alert others when firing.

3. Firing the Kiln

a) CAUTION: If you solely rely on the kiln sitter/controller to gauge the firing status, you risk over-firing your kiln.

b) NEVER FIRE THE KILN UNATTENDED. c) Set the timer. d) Push in the kiln sitter's plunger to start the firing. e) Close the lid-do not attempt to use the kiln with the lid open. Do not

touch the kiln’s surface. f) If the kiln is firing unevenly; e.g. top section is firing hotter than other

sections (indicated by a variation in the cones), manually adjust the kiln by increasing or decreasing switches at each zone.

g) Allow the kiln to fire until witness cones indicate that firing is complete. h) When complete, turn all switches to the "off" position

4. After using the Kiln

a) Turn off the kiln when not in use. b) Never open the kiln unless you know it is cool. Allow sufficient time for

kiln to completely cool and use extreme caution before unloading c) Clean the kiln to remove contaminants. d) Clean the surrounding area. NEVER clean the kiln while it is running.





Equipment Name/Description: Electric Kiln


Devices/locks: 1





Electrical Remote junction or breaker box

Plastic breaker adaptor Stop machine, flip breaker switch to the off position, install plastic breaker adaptor, lock, and tag.





DAILY ✔ Ensure that power cords are free of frays and damage and positioned so that they do not touch the side of the kiln.

Ensure that the kiln is secure with a level stand that does not teeter-an uneven stand is a safety hazard and may put stress in the kiln during firing (if stand is not level, place firm shims under the kiln stand legs until stand is level).

Ensure that the area around the kiln is free of slip/trip hazards and kept dry and free of moisture.

Are flammable/combustible materials (e.g. paper, plastic) removed from the immediate area?

Ensure that the kiln, lid and floor bricks are free of large defects/cracks.(hairline cracks are ok). Ensure that the lid is in good condition and closing properly. Ensure that the lid brace is connected securely to the kiln and kiln lid. Ensure that the latches (that lock sections together) are securely fastened. Ensure that elements are not popping out of the grooves (careful, elements are very brittle when cold). To repair: heat the element until it is glowing orange; shut off and disconnect kiln. With a metal instrument, carefully push the element back into place and pin. Fire the kiln hotter than normal once in a while if the elements pop out regularly.

Ensure that the sensing rod of the Dawson Kiln Sitter® moves freely in the tube assembly, free from wear and properly calibrated (use the firing gauge to check the sitter's adjustment). Replace if they start to corrode or warp.

If your kiln is equipped with a Bartlett V6-CF™ automatic controller, check the thermocouples and replace them if they appear thin/corroded; if it breaks during a firing, the safety system will automatically shut off the kiln, resulting in an interrupted firing and potential ware damage.

Ensure that there are ware, witness cones and cone holders available. Ensure that there is adequate ventilation. WEEKLY ✔

Confirm that firing gauge is properly calibrated.

MONTHLY ✔ Check elements for aging or need of replacement. Vacuum element grooves.

Due to the expansion and contraction of heating, the electrical connections inside the switch panel may loosen; ensure that they are tight

Ensure that the lid is free from brick particles; remove glaze spots from bricks.

Wipe shelves clean, and apply kiln wash ONLY to the TOP of the shelves (to protect against glaze drips); NEVER APPLY KILN WASH TO THE LID/WALLS.

Shelves may need a new layer of kiln wash; occasionally old kiln wash must be completely removed with a scraper and wire brush and a new layer of kiln wash evenly re-applied.

d) Move the carriage back and forth to flatten. e) Ensure that the material and canvasses/boards are kept flat. f) Move the carriage all the way to the end of the bed. g) Make the desired passes until the clay is compressed. h) Once compressed, return the carriage to the original position-do not slam

it against the end of the frame. i) Remove the top canvas and the compressed clay.
