Safety: Common Lab Practices You Must Complete Chemical Safety - PowerPoint PPT Presentation

Safety: Common Lab Practices You Must Complete Chemical Safety Training (unless you have already done so) with Nancy Apple before you can work in the laboratory: E-mail Amanda Hautaniemi Abrams (amhautan@mtholyoke.edu) to setup an appointment You Must Complete the Training with your faculty supervisor Main topics: • Emergency Contacts and Procedures • Chemical Hygiene • Working After Hours • Lab Citizenship • Stockroom Procedures and Hazardous Waste Management

Emergency Contacts • Chemical Spills - 1911 or 2304 (on campus, Public Safety) - 538-2304 (off campus or cell phone, Public Safety) • Biohazard Spills - 1911 or 2304 (on campus, Public Safety) - 538-2304 (off campus or cell phone, Public Safety) • Radiation Spills - 1911 or 2304 (on campus, Public Safety) - 538-2304 (off campus or cell phone, Public Safety) - 323-9571 (radiation safety officer) • Fire - 1911 or 2304 (on campus, Public Safety) - 538-2304 (off campus or cell phone, Public Safety) • Injury - 1911 or 2304 (on campus, Public Safety) - 538-2304 (off campus or cell phone, Public Safety)

Emergency Contacts • Phones - Know the location in your lab and in the hallways - Program the number into your cell phone 538-2304 (Public Safety) • Blue Boxes - Summon Public Safety and an officer will respond - Know the location in your lab and in the hallways • Fire Alarms - Alert occupants to evacuate the building - You still need to contact Public Safety - Know the location in your lab and in the hallways

Emergency Procedures What do I do? 1. Make sure everyone in the immediate vicinity is aware 2. Contain the emergency if safe to do so 3. If it can not be contained, or you are unsure, pull the alarm to evacuate the building 4. Summon aid: 1911 or 2304 (538-2304)

Emergency Procedures Fire! What do I do? • Know the location of exits : -from the room and from the building -know more than one route • Know the location of the: fire extinguisher emergency shower gas shutoff valve • Know the location of alarms and how to summon help

Emergency Procedures Fire! What do I do? There is a small, confined fire! 1. Can it be fought safely? - Is it small and confined to the immediate area it started in? 2. Yes 3. Remove source of ignition, smother the flame, close hood sash 4. Before using the fire extinguisher: 1. send someone for help 2. remove any flammable materials near the fire 3. have a safe escape route 4. know how to use the extinguisher – pull the pin, squeeze the handle

Emergency Procedures Fire! What do I do? There is a fire I can ’ t fight! 1. Can it be fought safely? -Is it too large/dangerous? 2. Yes 3. If the fire is in the hood, close the hood sash 4. Pull the alarm 5. Shut off the gas in the room 6. Evacuate the building 7. Give Public Safety and the fire department any information you can -location of fire, hazards in the area, location of emergency shut-offs

Emergency Procedures Fire! What do I do? I am on fire! 1. Stop, Drop, and Roll or Safety Shower 2. Summon help 3. Those helping should take care of the fire

Emergency Procedures Chemical Spill! What do I do? 1. What was spilled? -Assess the dangers of the material 2. No threat of fire or health hazards, and you know how to clean it up 3. Alert everyone in the lab 4. Make sure you are wearing lab coat, goggles, gloves (nitrile, not latex) 5. Contain spilled material in as small an area as possible 6. Clean up the material 7. Properly dispose of all contaminated materials

Emergency Procedures Chemical Spill! What do I do? 1. What was spilled? -Assess the dangers of the material 2. No threat of fire or health hazards and you don ’ t know how to clean it up 3. Alert everyone in the lab 4. Notify your faculty supervisor (or any faculty member) 5. The faculty member will determine how to clean it up

Emergency Procedures Chemical Spill! What do I do? 1. What was spilled? -Assess the dangers of the material 2. Threat of fire and/or health hazards 3. Alert everyone in the lab 4. Notify your faculty supervisor (or any faculty member) 5. Pull the fire alarm to evacuate the building if necessary

Emergency Procedures Chemicals on me! What do I do? 1. What was spilled? -Assess the dangers of the material 2. Contamination is minor: no health hazards, small area contaminated 3. Wash contaminated skin with soap and water 4. Remove clothing that was contaminated

Emergency Procedures Chemicals on me! What do I do? 1. What was spilled? -Assess the dangers of the material 2. Contamination is not minor 3. Use safety shower to thoroughly flush contaminated area 4. Remove clothing that was contaminated 5. Summon help – Public Safety 6. Notify your faculty supervisor (or any faculty member)

Emergency Procedures Chemicals in my eye! What do I do? 1. Go to eyewash station 2. Flush eyes for 15 minutes , eyes need to be held open, get eyes examined 3. Summon help – Public Safety 4. Notify your faculty supervisor (or any faculty member)

Emergency Procedures Personal Injury! What do I do? 1. Seek assistance of a faculty or staff member 2. Rescue the victim from life-threatening danger if it can be done safely 3. Summon Public Safety for any major injury The campus Health Center is closed until September 1 If the injury is minor: Treat with first aid supplies. If you want to go to a Hospital you will need to either transport yourself or find someone to take you. Public Safety will not provide transportation. Notify your faculty supervisor. If the injury is major: Call Public Safety for transport to a Hospital by ambulance. Notify your faculty supervisor. • What if it is a small cut? • What if it is a needle stick?

Chemical Hygiene Personal Protective Equipment 1. Gloves • Use the right glove for the job – nitrile is the default • No touching common items (doorknobs, hallway, pens, computers, etc.) • What if it rips or becomes contaminated? -remove, wash hands, replace 2. Goggles • Use the proper goggles for the job 3. Lab coat • When should you wear one? 4. Lab attire • Feet covered – no sandals or flip-flops • Hair tied back • What else? 5. Other equipment: masks, blast shields, respirators, monitoring badges

Chemical Hygiene Your Work Space 1. Keep it tidy • Clean up clutter • Clean up all spills • Do not store items in your work space • Organize materials so you are not reaching over glass, chemicals, heat 2. Store chemicals properly • Must be labeled with name and hazards • Store by hazard class 3. Work in the hood or on the bench? 4. Compressed gasses must be strapped during use, storage, and transport. • The safety cap must be during storage and transport and strapped to a cart when being transported

Chemical Hygiene Working with Chemicals 1. Using a chemical or performing a procedure • Read the label and Material Safety Data Sheet (MSDS) ( www.mtholyoke.edu/offices/srm/ehs/msdslinks.html) • Ask someone that has done it before • Make sure your work area is safe (heat source, flammables, etc.) • If it is dangerous notify someone in the lab before you begin 2. Transport chemicals properly • Must use secondary containment • 4 L or less: use a bucket • Greater than 4 L: use secondary container and place on a cart 3. Before you leave • Is your space tidy? • Is your reaction safe? (condensers secured, labeled, heat source) • Waste bottles closed? Hood sashes closed? Lights off?

Working After Hours Working 9:00 PM to 7:00 AM 1. Supervising Faculty member • Must review the procedure and hazards • Must determine if the student is adequately trained and experienced • Complete “ Permission to Work Independently ” form 2. Students • Must perform all work in accordance with approved procedures • Have written permission from supervising faculty member • Must be accompanied by a qualified person in the lab or within speaking distance

Lab Citizenship • No food in the lab • Keep the clean areas clean (no touching with gloves on, no chemicals, etc.) • Do not leave a mess • Do not use other’s glassware or borrow anything without asking first and returning the items when you are finished • Instrument use: -leave name and phone number if need to leave the instrument -sign the logbook, contact person to fix it if not working properly • Inform others when doing something dangerous -make sure they know what could go wrong and what they are supposed to do ASK IF YOU ARE UNSURE

Lab Citizenship • Think before you heat: -do you really need to heat -how will you control the heat -how will you make sure it will not go dry • Gas cylinders: -you must be trained before you can use them -make sure they are strapped to the bench -when transporting or not in use, make sure safety cap is on -when transporting always strap to a cart ASK IF YOU ARE UNSURE
