Presentation Transcript

Safety Web Site

  • Includes:
  • Department Hygiene Plan
  • Links to sites for MSDS
  • Link to NRC “Prudent Practices”
  • Compatibility Tables
  • Chart for choosing gloves
  • ACS Academic Lab Safety Guide

Who Makes the Rules?

  • Federal: OSHA, EPA
  • State: OSHA, DEP
  • Campus, System: SEM
  • We have to keep all these people happy….

Security Issues

  • All
  • Laboratories
  • Prep Rooms
  • Storage Rooms
  • must be kept locked when unoccupied.

Building Entrances

  • Locked after 10 PM weekdays, all day weekends, holidays
  • DO NOT prop open or unlock
  • Fire doors
  • Intended to help contain fire to one section of building
  • DO NOT prop open
  • Some doors stick when opened wide:

Every lab must have a copy of the Department chemical hygiene plan readily available

It includes the emergency action plan

Guidelines for all non-standard procedures should be added at the end of the plan


Personal Protective Equipment (PPE)

  • Goggles must be worn whenever anyone in the lab is working with chemicals
  • Gloves always used; face shields, blast shields, lab coats or aprons should be used depending on the task
  • These items must be available in every lab
  • PPE does not leave the laboratory suite
  • Sandals, shorts, and bare midriffs are not permitted in labs

Face shield

Blast shields

Tyvek lab coat (flame resistant)


Chemical Storage

  • Chemicals must be segregated by hazard category; color coding helps
  • Everything, including research samples, must be labeled with a chemical name or structure
  • Chemical stock bottles may not be left on benches or in hoods when not in use; always return to storage
  • MSDS must be readily available for all stored chemicals
  • Liquids greater than one pint require secondary containment

Three Core Ideas for Storage

  • Keep things that would react with each other separate
  • Prevent accidental selection of dangerous substances by segregated storage
  • Prevent contamination: keep containers clean

Storage Categories

  • Flammable solvents in fireproof cabinets
  • Acids and bases separate
  • Oxidizers and reducers separate
  • Carcinogens, suspected carcinogens
  • Other toxic substances
  • Harmless substances

Secondary Containment for Liquids Over One Pint : Issues

  • Plastic coated bottles: containment still required for waste; optional but preferred for others
  • Storage cupboards with built-in containment: secondary containment required if more than one substance stored

Waste Disposal

  • Wastes must be placed in secure containers, segregated by hazard category
  • Amount, identity, and date of addition to container must be recorded
  • Waste storage location may not be used for anything else
  • Waste containers must be inspected every business day; the inspector must sign the form
  • Arrange waste pickup frequently

Waste Pickup

Email to:

Provide approximate quantity; note special hazards

Copy the email to:

Inform Ray Fort if waste is not collected



  • The sounding of the alarm announces an emergency; you must leave the building immediately
  • Congregate at the “rally point” in front of Wingate Hall; inside Wingate in bad weather
  • Re-enter Aubert only when given permission
  • Other situations are emergencies only if you determine them to be beyond your ability to cope
chemical spills
Chemical Spills
  • A spill kit must be kept in every lab
  • A good spill kit contains:
    • Kitty litter or other absorbent
    • Dust pan and brush
    • Heavy plastic bag
    • Tape or wire to seal bag
  • Kit must be labeled clearly and be readily accessible
  • Bag containing waste must be labeled
  • Laboratories must be kept neat and organized
  • Bench top clutter is both unsafe and a violation of OSHA rules
  • This particularly applies to reagent bottles; return to storage immediately after use
  • Move dirty glassware immediately to a tub at the washing area; wash up every day


  • All accidents (spills, fires, personal injury) must be reported in writing to Ray Fort; email is OK
  • For spills: What was spilled, approximately how much, cleanup procedure
  • Injuries: who was injured, how, resolution; in teaching labs, name of TA

Fires: Who was responsible, what burned, approximately what quantity, how fire was extinguished

  • Note: only small solvent fires should be extinguished by lab personnel!
  • Pull down hood door; let burn out
  • Smother
  • Clothing fire: shower or drop and roll
  • Evacuate and pull alarm for all others.

Fatal Accident at UCLA in 2009

  • Student severely burned; later died
  • Working alone, without protective clothing
  • Syringing tBuLi; accidentally pulled plunger out
  • Polyester sweater went up in flames
  • Student ran away from safety shower
  • University had no records of safety training, and did not enforce rule against working alone

The Los Angeles County prosecutor brought criminal charges against the university and the faculty advisor, Patrick Harran

The university settled out of court: a $500,000 scholarship in environmental law was established, and a safety training program was put in place across the UCal system

Criminal charges are still pending against Harran; he faces 4.5 years in prison if convicted


Know the properties of the substances you work with!

Use appropriate protective equipment!

Keep an accurate, complete notebook!

teaching laboratories
Teaching Laboratories
  • Teaching assistants are responsible for enforcing safety rules
  • This includes proper clothing and wearing of gloves and goggles
  • Do not argue with students who disobey rules; get faculty or staff help
