Standard Operating Procedure (SOP) For using a Drill Press #1 General Process Description The drill press is used to drill holes into work pieces of different materials. All work described in this SOP will have to be conducted in JHE 242. You MUST have WHMIS training prior to working in the lab; users must be properly trained on this piece of equipment. Contact Person is Ed McCaffery Laboratory Manager (Room JHE 248 ext 24985). This SOP is from 03/06/2008. #2 Hazards of Drill Press/ Class of Hazard The major risk of this equipment is pinch (mechanical hazard), and cut injury. #3 Personal Protective Equipment (PPE) Before using the Drill Press, ensure that you will at least meet the following protective requirements: 1. Safety Glasses 2. Closed-toe shoes with socks 3. Long pants (no shorts!) 4. Lab coat (Optional) 5. No loose clothing, no jewelry, long hair must be tied back. Before proceeding you must have read and are familiar with the safe operations of the Drill Press. #4 Engineering / Ventilation Controls There is no engineering or ventilation controls required for this piece of equipment. #5 Special Handling Procedures and Storage Requirements Make sure that the sample being drilled is securely attached to the table either using the vice or by clamping it down to the table; frequently expediency dictates that the material is hand held for a quick drill and this can become very dangerous if the drill bit locks to the material and the material spins freely. Before drilling the sample a center drill should be used. A center drill has a thick shaft and very short flutes. It is therefore very stiff and won't walk as the hole is getting started. It doesn't cut as easily as a drill bit, so you should use cutting fluid. Do not use the drill unless you have been properly trained by one of the Technical staff in MSE. Inspect the cutting tool is sharp, and has no damage. No loose clothing and hair must be tied backed.

SOP –Drill Press. #6 Accident Procedures If you are injured using this piece of equipment; depending on the severity of the injury either go to the First Aid station (JHE 140) for first aid and fill out an incident report or if the injury is severe call 88 and receive medical attention immediately. If an injury does occurs, make sure the area is quarantined off, do not clean the area if an accident occurs, the emergency response team must assess the accident scene to assess what occurred, leave the room and call 88 immediately, then EOHSS Ext 23314 and Ed McCaffery Ext 24895. #7 Waste Disposal When cleaning the drill press of the cuttings make sure to use a brush and dust pan; the cuttings are very sharp and can cut flesh. Any cuttings can be disposed into the garbage. #8 Training requirements Prior to entering and working in the laboratory, you must have completed the EOHSS WHMIS training. You will have to retain training documentation for at least one year. Any person conducting work in JHE 242 using this SOP must receive training on the contents of this SOP. #9 Approval Required All research staff, students, and Graduate students must be trained prior to starting work with the Charpy Impact Tester. If working after hours you have to ask for approval from your Supervisor and the Person In-charge, Laboratory Manager Ed McCaffery. #10 Decontamination When finished; wipe area down using a brush and dust pan; remove the cutting tool from the chuck. #11 Designated Area Upon leaving a designated work area, remove any personal protective equipment worn and wash hands. After each use (or day), wipe down the immediate work area. At the end of each project, thoroughly decontaminate the designated area before resuming normal laboratory work in the area.

SOP – Drill Press #12 Precise Process Description 1. Turn power on from wall breaker. 2. Clamp sample down either using a vice or clamping the sample on the table. 3. Inspect the cutting tool for any damage. 4. Insert the cutting tool into the chuck and tighten using the chuck key. Once tighten remove the chuck key immediately. 5. It is essential that you wear safety glasses. You must wear closed toe shoes and long pants. No loose clothing, no jewelry, and if you have long hair it must be tied back 6. Switch on the drill press, and use the center drill to start the drill hole (make sure you use lubrication). 7. Replace the centering tool with the drill bit and drill out the hole. Do Not put too much pressure on the drill bit (especially if it is a small diameter), the bit can break and become a projectile. Make sure adequate lubrication is used. 8. Once all holes have been drill out take the drill bit out of the chuck, remembering to take the chuck key out of the chuck once the bit is out. 9. Turn the power off at the wall breaker. 10. Clean up the area of any debris, and lubricant. LOCK OUT TAG OUT PROCEDURE For routine maintenance to the motor or drive belt the Drill Press MUST be LOCKED OUT AND TAGGED OUT! 1. Turn power switch off to machine. 2. Turn off power to main breaker on wall. 3. Put your own lock into the lock out hole, and place tag with lock. 4. Check the power is now off first by turning on Drill Press, then with a volt meter check there is no power at the terminal. 5. Perform maintenance or change belts. 6. Once maintenance is complete remove lock and tag and turn on main breaker. 7. Follow “Precise Process Description”.

Safety Rules for Drill Press 1. All drill press users must know how to operate a drill press properly and safely. Do not operate a drill press if it is damaged and report the damage to the technical staff. The technical staff can provide instructions on the safe and proper operation of the drill press. 2. Certain materials are hazardous to drill. Check the MSDS on your material. Ceramics or refractories containing crystalline silica is a designated substance require special handling practices; wet drilling is preferred. 3. Always wear proper eye protection (see McMaster Eye Protection Policy). Keep hands away from the cutting surfaces and all moving parts. 4. Do not wear loose clothing, gloves, neckties, rings, bracelets or other jewelry that can become caught in the drill press. Secure loose clothing and long hair. Do not use rags near moving parts of drill press. 5. The belt guard on the drill press must be locked in place. 6. Use a clamp or vice to hold the work piece in place on the table and prevent work piece from spinning. DO NOT hand hold the work piece when drilling. 7. Ensure that all drill bits are clean and sharp so they can cut freely without being forced. 8. Make sure the drill bit or cutting tool is locked securely in the chuck. REMOVE the chuck key before starting the drill press. Shut off the power before removing the drill bit. 9. Stop the machine before measuring, cleaning or making any adjustments. Ensure that the start/stop switch is within easy reach when the drill press is in use. 10. Adjust the position of the table so that drilling is done into the work piece only and not the table, vice, clamps, etc. 11. Lubrication (oils or water soluble oil mixture) should be used when drilling metallic materials. Remove burrs and chips from the drill hole. When making deep holes, clean out the hole frequently. Reduce the drilling pressure when the drill begins to break through the work piece. This action prevents the drill bit from pulling into the work and breaking. 12. Keep the table clean or scrap, tools, and materials. Make sure to clean up around the drill press and table using a brush. Do not remove chips by hand or while the

September 18, 2013 drill is running. Keep the floor around the drill press free of oil and chips. Do not use compressed air to clean up the chips.
