Who Makes the Rules?
o Federal: OSHA, EPA
o State: OSHA, DEP
o Campus, System: SEM
We have to keep all these people happy
…. And ourselves safe
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:
CLOSE THEM!
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; structure may be
added
§ 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
o Flammable solvents in fireproof
cabinets
o Acids and bases separate
o Oxidizers and reducers separate
o Carcinogens, suspected carcinogens
o Other toxic substances
o Harmless substances
Secondary Containment for Liquids Over
One Pint : Issues
o Plastic coated bottles: containment
still required for waste; optional but
preferred for others
o 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:
[email protected]
Provide approximate quantity; note
special hazards
Copy the email to:
[email protected]
Inform Ray Fort if waste is not
collected
Emergencies
§ 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
 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
Housekeeping
§ 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
Accidents
 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!
o Pull down hood door; let burn out
o Smother
o Clothing fire: shower or drop and roll
Evacuate and pull alarm for all others.
Fatal Accident at UCLA in 2009
o Student severely burned; later died
o Working alone, without protective clothing
o Syringing tBuLi; accidentally pulled plunger out
o Polyester sweater went up in flames
o 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
A plea deal was worked out on criminal charges
against Harran: $10,000 fine; 800 hr community
service; develop gen chem or organic course
and teach at a community college
Accident at Colorado College
 Students were “drilling into” pressurized
container of TiCl4
 Contents were suddenly released
 13 people were hospitalized; one in serious
condition
Problems from our last inspection
Know the properties of the
substances you work with!
Use appropriate protective
equipment!
Keep an accurate,
complete notebook!
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
