Environmental Health & Safety
Occupational Safety & Health Administration Protect employees from physical and health hazards Outlines written Chemical Hygiene Plan
Describes chemical hazards Storing chemicals Handling chemicals Selection & Use of Proper Personal Protective Equipment (PPE) Establish safety principles Emergency procedures
Any substance which poses a physical or health hazard Can cause, 1. Physical injury 2. Acute or Chronic health effects
Material Safety Data Sheets Professors EH&S Google! Vital to your safety Determines proper precautions
Harm is caused by contact (exposure) Inhalation, Ingestion, and Absorption To reduce potential harm & exposure
Be cautious and be professional. Use Proper Clothing, PPE, fume hoods, etc. Reduce quantities or use less hazardous substances Different routes for exposures are Splashes, Spills, Fumes, Fires, your mouth, PPE, etc.
Use a cart or a bottle carrier when moving chemicals outside the lab Ensure containers are in good condition Wear gloves Wash hands regularly
Proper labeling Keep incompatible substances apart Utilize flammable and corrosive cabinets Do not store liquids on shelves above eye level Identify unwanted containers for disposal Minimize quantities stored in your lab
Access to Sinks, sewer, floor drains, and fume hood cup sinks should be avoided. 100% of largest container Separating incompatibles Vacuum pumps
Must accurately describe the contents and hazards Must be legible Do not use nomenclature or abbreviations Create reference list for small containers
Keep all containers closed Close/Tighten top lid Tin foil, parafilm, stoppers, etc. Prevent evaporation and spills
Pressurized glass Compressed gases Broken glass Sharps Biomedical Radiation Cryogenics Water Reactives Mercury
Clothing or accessories designed to protect Glasses, goggles, face shields, lab coats, gloves, respirators, etc. Cotton fabric, closed toed shoes, pants, etc.
Eye protection is required ANSI Z87 devices minimum Chemical splash goggles required when potential of chemical splash exists
Locate. Identify easiest and quickest route. Knowledge of their operability. Flush Eye Wash once every 2 weeks.
Identify & Locate
Fume hoods Fire extinguishers Eyewashes Emergency showers Glove boxes Sharps containers Emergency phones MSDS files Spill kits Evacuation routes Fire alarms Flammable cabinets Sprinkler systems
Emergency Situation ◦ Fire or explosion ◦ Large spill or spill of unknown substance ◦ Gas release or overpowering fumes ◦ Evacuate and call for help Non-Emergency Situations ◦ Training ◦ Location of Spill Kit ◦ Proper PPE ◦ Proper Disposal
Passages must be kept clear, no trip hazards Workbenches kept free of clutter Never block exits or emergency equipment No unlabeled chemicals Clean spills immediately Avoid cluttering fume hoods. No liquids above eye level Keep your area organized
Suspected or known to be exposed to chemicals are to receive prompt medical attention ◦ Contact supervisor ◦ Complete exposure assessment form ◦ Exposure evaluation completed by medical professional
Prepare for lab Plan Obtain PPE Conduct Housekeeping Exiting lab
Bucknell is required to provide training You may create hazardous waste Hazardous wastes must be disposed off properly Review the written Hazardous Waste Plan
Declared waste When the generator declares the material has no further use and is to be discarded
Inherently waste-like o Containers in bad condition o Obviously waste, in bad condition, leaking, abandoned, rusty, bulged out or in, tears and cracks, etc.
Its listed as a HW by the EPA - (P, U, K & F) Its characteristics makes it a HW. ◦ Ignitability ◦ Corrosivity ◦ Reactivity ◦ Toxicity
Are fatal in low doses Are to be collected alone Expensive disposal 1 quart SAA limit
Identify all your waste streams Complete a HWDC Form for each waste stream
Aqueous (Inorganic) Waste ◦ Acids, bases, and heavy metals ◦ Do not mix acids and bases Halogenated Organic Waste ◦ Organic compounds that are brominated, chlorinated, fluorinated, iodated Non-halogenated Organic Waste ◦ All other organic compounds
Under the control of a single generator Accumulate waste at the point of generation Accumulate waste up to a year Accumulate a maximum of 55 gallons
Collect all identified hazardous waste HW cannot be disposed to the sink, evaporated, neutralized, diluted, etc. HW containers must be: ◦ Compatible with the HW it is storing ◦ Maintained in good condition ◦ Kept closed except when adding waste
The words “Hazardous Waste” A start accumulation date The list of contents with approximate proportions
Contain 100% of the largest container Segregate incompatible wastes Clean or report releases to secondary containers immediately Containersx Capacity = Secondary 3x 4 liters = 4 liters 1 x 4 liters = 4 liters 2 x 5 gallons= 5 gallons
Chemical containers can be thrown in the trash once they are considered empty Empty= Less than 3% residual by weight Acutely hazardous containers must be collected for EH&S Mark barcode as empty, deface label, and remove lid Use your discretion
Collect all BU supplied spray cans Generally 6% residual remains after spraying Collect within SAAs
Universal Waste Batteries All types of batteries are collected Collect batteries in containers labeled “Universal Waste Batteries”
Inspect waste containers Proper labeling Signs of container damage Spilled waste in secondary trays
During a chemical waste emergency… Pull a fire alarm Evacuate the area Call Public Safety
In case of a spill For waste determinations To implement a SAA To have waste containers removed To request labels With any questions and concerns
