Eye protection, gloves & lab coats Goggles required for all classes ANSI Z87.1, non vented Sold by Chem. Office at the beginning of each quarter Gloves – provided by the Department for all classes and research labs Type: vinyl, non-powdered; for Organic classes: Nitrile. Laboratory coats required in all classes and available in SU Bookstore ( ~$27.00, XL $31.50)
First Aid Kits locations: Stockrooms 514 & 609 Quant Lab. 507 (between 507 and 506) Organic Lab 603 Main Chemistry Office: 516 All research labs
EMERGENCY PROCEDURES Chemical burns: wash affected body parts with cold water for 15 minutes; Exceptions: HF, Na, K, Phosphorous (see CHP for specific instructions) Do not attempt to neutralize!!!! Organic burns – use hand soap to emulsify organic substance, wash w/water Eyes: wash w/water for 15 minutes in eye wash fountain Evaluate the burns and sent a victim to the Health Center
CAMPUS HEALTH CENTER: Located in Bellarmine Hall Phone # (206) 296-6300 Open Mon- Fri 7:00-5:00 When closed – go to Swedish, Providence or Harborview Emergency Departments Telephone ##: Swedish 386-2573; Providence: 320-2111; Harborview: 731-3074 Telephones located in the 5-th and 6-th floor hallways, room BA601and Stockroom BA609
LIFE THREATENNING CONDITIONS Difficulty breathing Major injuries: open wounds, spinal or neck, obvious fracture..etc. Unconsciousness or unresponsiveness SU Emergency line # -5911
EVACUATION ROUTES Always use stairs, check reassembly areas assigned to different buildings on campus BANNAN in front of the Law School flag pole (picture) There will be an “evacuation drill” some times during the school year.
Evacuation assembly area for Bannan building: by the Law School flagpole
Evacuation procedure: Stop what you are doing and walk, not run, to the nearest stairwell. Close all doors behind you. Use the stairs, do not use elevators. If the powers fails, you may become trapped in the elevator. Once evacuated, proceed to your designated gathering area. Do so in an orderly manner, do not panic. In assembly area report to your instructor/supervisor fr a headcount. Do not re-enter the building until the “all clear” announcement is given by the emergency coordinator.
FIRE HAZARD Each lab is equipped with ABC extinguisher, located by the door and labeled In case of the fire not possible to handle with the extinguisher– activate the fire alarms and evacuate!! Fire alarms are located at the opposite sides of each hallway (picture)
INCIDENT/ ACCIDENT REPORTS Fill up a “Chemistry Department Incident Report Form” – available in each laboratory. Give one copy to Kasia, keep one. We will archive them on SU Network and eventually use for safety discussion. Accidents as: injuries, fires and spills should also be reported to Public Safety.
“Reportable Accidents” Each injury, fire and “spill” in the laboratory should be reported to Public Safety Department in order to make an official “Accident Report” Call -5990 or –5911 The officers will show up in the lab to fill out the required forms
CHEMICAL SPILLS Immediate action: confine and neutralize if possible to handle. Examples of spills which would require evacuation: - Bromine> 50 ml and not in the hood -Mercury > 1 thermometer bulb -Extremely hazardous chemicals > 1 L. Call Public Safety Office at -5911, they will contact Emergence Response Team to clean up the lab.
ORDERING, INVENTORY & STORAGE Monthly PO# ( ask Doris) The chemicals will be delivered to the Stockroom, inventoried and delivered to you Inventory : bar-coded system by VERTERE Kasia & Deanna are “administrators” eligible to make entries/changes “Read only” copy – available in T drive under “Chemical and lab inventories” No password required To remove used reagents from inventory list: return an empty bottle with bar-code label to the Stockroom or remove the label and stick on the designated log.
CHEMICAL STORAGE LOCATIONS: BA610 – main chemical storage area BA605&604 under hoods: Corrosive acids and bases BA603 under hoods: Hexanes, Ethyl Acetate, Halogenated solvents Research chemicals: in individual research labs and BA612/B ( solvent purification room) BA514 Stockroom: limited amounts of basic chemicals for lecture demonstrations Teaching labs: limited amount of chemicals for students’ experiments
Relocation procedures: Sign relocations sheet ( on the door of storage areas) Needed are: date, bar-code number & new location This is to keep the inventory updated
Barcode NumberNew Location (Room #)Your professor’s name Chemical Relocation Log Please add the following information when removing any chemical reagent from this lab.
Please, remove barcodes from empty reagent bottles and stick them here:
TOXIC Chemical Reagents LD50 (LC50) – experimental value, lowest dose which kills 50% population of tested animals (rats, mice, guinea pigs…) – always indicated what animal and the route of exposure LDLo – lowest published lethal dose (humans too) Conversion factors for human doses: Rat x 0.142 Mose x 0.066 Guinea pigs x 0.179
Classes of Toxic Chemicals RatingOral LD50 (rat) mg/kg body Probable lethal dose for Man 1. Extremely T.11 grain ( drop) 2.Highly T.1-504 ml ( 1 tsp.) 3.Moderately T.50-50030 ml ( 1 fl.oz.) 4. Slightly T.500-5,000600 ml 5. Practically Non-Toxic 5,000-15,0001 L 6. Relatively harmless >15,000
Finding Toxicity Data: www.hazard.com Go to: (SIRI) MSDS Index Go to: Chemical Toxicity Data Use chemical name or CAS# Look for LD50/LC50…etc

(120 question that could save your life)
Lab safety elements in SU Chemistry courses: Initial General Chemistry training In class discussion, video, in lab activity, Lab safety contract, quiz CH 131: Labeling activity CH132: MSDS activity CH 133: Toxicity/LD50 activity Organic Chemistry: first lab training, safety teams and post lab reports
Laboratory ventilation To keep the hoods working properly the doors and windows in the labs should be kept closed all the time
