1 Department of Mining and Materials Engineering Materials Engineering Orientation and Safety Guidelines

2 Welcome to Materials Engineering at McGill! This presentation is intended to give a general introduction to the facilities and safety policies particular to Materials Engineering. Attendance is required for: New graduate students in Materials Engineering Visiting researchers and long-term lab users Students in the SURE program doing research in the department

3 Safety Begins with you. It is your responsibility to conduct experiments safely. Evaluate the risks of your processes. Establish Standard Operating Procedures (SOPs) To help evaluate these risks use: 1. Your advisor 2. Technicians 3. McGill EHS

4 Safety Begins with you. Before you begin a new procedure 1. Evaluate the risks 2. Determine the worst-case scenarios 3. Plan for the worst-case scenarios After developing SOPs 1. Evaluate the effectiveness of your SOP

5 Safety Begins with you. 1. Be aware of your surroundings 2. Politely correct others not following safety guidelines (personally or anonymously) 3. Evaluate your surroundings for unsafe procedures since they can harm you

6 Internal Responsibility System

7 Overview of the Department Research Breakdown Materials Processing: Mineral processing Metals processing Aqueous processing Pyrometallurgical processing Materials Science: Aerospace and automotive materials Biomaterials and tissue engineering Computer aided modeling Materials characterization Electronic materials Surface science and engineering Nanomaterials The safety needs of this department are diverse!

8 Why do we train for safety? Etchant Explosion in Wong 0250 Fire in the Foundry

9 Know your surroundings Before you begin lab work know the location of: Safety Shower(s) Eyewash(es) Fire Extinquisher(s) Fire Exits

10 Wong Building Basement

11 Wong Building First Floor

12 Wong Building Second Floor

13 Wong Building Third Floor

14 Adams Building

15 Personal Protective Equipment (PPE) Evaluate your risks and determine the proper PPE Examples of PPE: Lab Coat Eye Protection Gloves Apron Face shield

16 In Lab Lab coat and eye protection should be worn (Gloves may also be required) Outside Lab Lab coat and gloves should be removed (Transporting chemicals can be an exception)

17 Lab Coat laundry service Pierre Vermette coordinates Give lab coat to him with: Full Name on paper attached to lab coat Each person can clean their coat once per year

18 Gloves-not all created the same Different gloves for different reasons! Chloroprene Latex Nitrile Know which is right for your needs

19 High Temperature gloves

20 Choosing a glove (Resources) Best to check more than one (Best Co.) (MAPA Professionals) (Showabest Gloves)

21 Fume hood operation Ensure exhaust is working Minimize materials in the hood Keep sash as low as possible and not higher than your face Do not work on ledge

22 Fume Hood Operation Why you cannot work on the sash

23 Chemical Handling (Transportation) Double Contain the chemical Wear relevant PPE Use cart, if possible/necessary

24 Chemical Handling (Use) Know what reaction will ensue before mixing chemicals and take the proper precautions.

25 Chemical Handling (Storage) Label chemicals! Store with compatible chemicals Store in proper container Store in air-tight container Chemical compatibility resource

26 Chemical Handling (Storage) Important to separate incompatible chemicals Example: Chlorine and ammonia (Chlorine gas and possibly hydrazine, Chlorine was a weapon used in WWI) Example: Copper and H2O2, strongly reacts produces O2, could build pressure in a vessel. Chemical compatibility resource

27 Chemical Handling (Storage)

28 Chemical Handling (Storage)

29 Chemical Handling (Storage) Check for expiration dates of some chemicals

30 Chemical Handling (Waste) Place in properly-labeled waste container Mix only compatible chemicals in waste container Dispose of waste container by contacting Monique or Robert.

31 Disposal of Solids, Liquids and Sharps Different disposal containers and regulations for different forms of waste..

32 Disposal of Solids, Liquids and Sharps Different disposal containers and regualations for different forms of waste..

33 Chemical Handling (Waste) Besides the standard disposal containers, you can use others, not provided (required for certain chemicals). EHS will pick these up directly from your lab

34 Disposal of Solids, Liquids and Sharps

35 Disposal of Solids, Liquids and Sharps

36 Spills and clean up (small and large spills)

37 Spills and clean up (small and large spills) Anticipate spills, prepare for them ahead of time. You and your advisor are responsible for this. Need help? Contact EHS x4563

38 Spills and clean up (small and large spills)

39 Spills and clean up (small and large spills)

40 Gas Cylinders Ensure cap is screwed on tightly Use cart to transport Chain cylinder to wall

41 Gas Cylinders (Connection) Do not over tighten regulator fitting, if possible, use Torque Wrench Open valve slowly Do not leave valve completely open (could get stuck in open position)

42 Electrical Shock Prevention X

43 Electrical Shock Prevention X

44 Safety Showers In case of spill Walk quickly (do not run) to safety shower Remove soiled clothing Rinse for 15 min Certain chemicals require Special procedures, e.g. HF.

45 Eyewash Walk to eyewash Flush eyes for at least 15 min Blink constantly while water is flowing over eyes

46 Fire On you? Stop, drop, and roll.

47 Materials Safety Data Sheets (MSDSs) List the hazards and precautions which should be taken with a chemical Required for each chemical in your lab Located online mylab.mcgill.ca

48 Chemical Inventory Required as an index to the MSDS folder Required electronic list to EHS Chemical Vendor Chemical Abstract Service Number (CAS#) Amount (# and size of containers) Location within lab Physical phase (solid, liquid, vapor) Lab room #

49 Chemical Inventory: mylab Input and update chemicals in mylab Replaces MSDS sheets in binders Access is granted through your supervisor (Supervisors request through Parrisa Parang in EHS) mylab.mcgill.ca

50 First Aid (kit requirements) Approved first aid manual Bandage scissors Splinter forceps 12 safety pins 25 sterile band (25 x 75 mm 2 ) 25 sterile gauze squares (101.6 x mm 2 ) 4 rolls sterile gauze (50 mm x 9 m) 4 rolls sterile gauze (101.6 x 9 m) 6 triangular bandages 4 sterile bandage compresses (101.6 x mm 2 ) Adhesive tape (25 mm x 9 m) Antiseptics

51 First Aid Automatic Electric Defibralator (AED) Closest one is in the lobby of the Genome building.

52 First Aid

53 Fire Safety

54 Fire Safety If the fire is small and you have the appropriate type of fire extinguisher available, you may attempt to put it out. Once it is contained and extinguished, call McGill Security at Immediately report ALL uncontained fires. Pull the fire alarm, advise others to evacuate (and do so yourself), and call McGill Security followed by 911. You are responsible for reporting all known information about the situation to security and/or firefighting personnel.

55 Choosing a Fire Extinguisher General solid combustibles: Paper, wood, cloth, rubber, plastics, etc. Label with appropriate fires Flammable liquids: Solvents, oils, greases, etc. Electrical fires: Wiring, motors, etc. Combustible metals: Powders or shavings of magnesium, titanium, aluminum, etc. Type ABC fire extinguishers are located in the hallways on each floor of the Wong Building. These are appropriate for most small laboratory fires. Type D fire extinguishers must be available whenever metal powders or shavings are being handled.

56 Aim the hose or nozzle at the base of the fire. Pull the pin completely!!! Squeeze the lever Sweep the agent

57 Emergency Telephone Numbers Situations requiring immediate internal assistance Call McGill Security: Chemical spills Flooding If you use a fire extinguisher Any other reason you would want a security officer present Emergencies requiring immediate outside help Call 911 then call McGill Security: Montreal Police Montreal Fire Department Ambulance Service Emergency services will need to be escorted by McGill Security. Therefore, if you ever call 911, call McGill Security afterward.

58 Useful Contact Information McGill Facilities for the Wong Building Facilities Call Centre: Website: (24 hours) Wong Building Porter: Michael Yakobina Daytime phone: (7:00 14:45) Custodial daytime pager: (7:00 14:45) Custodial evening pager: (16:15 24:00) McGill Security non-emergency Phone: (24 hours) McGill Facilities or the porter should be contacted for issues of building cleanliness, routine maintenance, and general functionality.
