Environmental Health and Safety Programs at SUNY
Brockport

• Asbestos
• Fire Safety
• Chemical Inventory

• Indoor Air Quality
• Bloodborne Pathogens
• Confined Spaces
• Respiratory Protection

Definition of Toxicity

• label term LD50 LC50(ppm)
• Nontoxic gt5 g/kg gt20,000
• Toxic .05-5.0 200-20,000
• Highly toxic lt.05 lt200
• Danger - toxic potential
• Warning - less toxic potential
• Caution - least toxic potential

4
Dose IS the poison

• LD50 - the dose in g/kg ingested that will kill
  50 of the animals (not humans)
• LC50 - the concentration in the air (PPM or
  mg/m3) that will kill 50
• LD/LC lo - the dose at which ANY effect is
  demonstrated
• IDLH - immediately dangerous to life and health
  GET THE HELL OUT!!!!!!!!

5
PATHWAY IN YOUR THE LUNGS
6
GASES

• a formless liquid that expands to fill a space
• a mixture containing different molecules
• once mixed they stay mixed
• vary greatly in toxicity - O2 needed to live
• hydrochloric acid gas
• chlorine gas
• inert but can displace O2 asphyxiant

7
VAPORS

• gaseous forms of liquids
• water - evaporates condenses rain
• vaporization point boiling point (not so)
• higher temperatures more vapors
• solids can vaporize (ex.-mothballs / naptha)
• solvents such as turpentine, mineral spirits,
  stoddard solvent, gasoline, etc. all vaporize
• vary greatly in toxicity

8
MISTS

• TINY LIQUID DROPLETS IN THE AIR
• ANY LIQUID CAN BE MISTED
• THE FINER THE SIZE, THE DEEPER IT IS INHALED
• A MIST OF A SUBSTANCE IS MORE TOXIC THAN A VAPOR
  IN THE SAME CONCENTRATION - IT DELIVERS MATERIAL
  TO A SPOT RATHER THAN DISPERSED THROUGHOUT.

9
FUMES

• very tiny particles usually created by heat
• diameter 0.01 to 0.5 microns
• can remain suspended for long periods of time
• eventually will settle
• bluish haze from soldering or welding
• more toxic due to small particle size
• metals, organic chemicals, plastics, silica will
  fume

10
DUSTS

• when solid material is broken down
• 40-60 in household is dead skin
• sanding, sawing, grinding, etc.
• the finer the dust the deeper into the lungs
• Respirable dust 0.5 to 10 microns
• Asbestos is a needle like structure and size is
  0.5-2.0 microns and very stable
• toxic materials can also disolve in the lungs or
  digestive system

11
SMOKE

• BURNING OF ORGANIC MATTER
• USUALLY CO2 AND WATER GIVEN OFF
• CAN CONTAIN FUMES, VAPORS, GASES, AND OTHER HEAVY
  METALS INCLUDING TOXICS
• CIGARETTES 4,000 CHEMICALS AND CO GAS, BENZENE
  VAPOR, FUME SIZED PARTICLES OF TAR

12
RIGHT-TO-KNOW STANDARD

• Evaluating hazards
• MSDSs
• Labeling
• Training
• Written Program
• Inventory of chemicals

13
EVALUATING HAZARDS

• Manufacturer responsible
• Employer responsible to train/provide info
• Material Safety Data Sheets - must have
• Awareness of hazards - employee
• Long term v.s. short term exposure
• Overexposure v.s. exposure

14
MATERIAL SAFETY DATA SHEETs

• Uniform outline - yes no
• Accessible to employees - each shift
• Employer responsible to obtain
• Hazardous Ingredients
• - 1 if hazardous must be listed
• -0.1 if acutely hazardous must be listed
• Know where they are located in your area
• Web site www.siri.uvm.edu/msds/link.html

15
IMPORTANT POINTS ON MSDS

• Get the name exactly right
• How current is it - 3 years plus ?????
• PEL - Permissible Exposure Limit (OSHA)
• TLV - Threshold Limit Value (ACGIH)
• of material, concentrate or mix
• Call manufacturer for more info
• Use more than one source, especially if ?s

16
Technical info on MSDS

• Vapor pressure -gt higher wants to get out
• Vapor density -gt 1.0 air, gt1 heavy, lt1 light
• Specific gravity -gt 1.0 is water
• Evaporation rate -gt 1.0 butyl acetate, 3.0 is
  fast, less then 0.8 is slow
• Volatile -gt air emissions
• Flash point -gt Temp. _at_ vapors can ignite
• Upper and lower flammability limits

17
Health Hazard Data

• PELs and TLVs below 50 PPM? be careful
• Acute - quick onset and quick recover
• Chronic - long duration, lasting effects
• Symptoms of exposure headache, nausea,
  dizziness, lethargy, depressant, specifics
• Target organs - liver, kidneys, brain, etc.
• Dose is the key

18
Routes of Entry

• INHALATION - most common
• DERMAL - skin absorption, cuts, hands
• INGESTION - labeling, eating, smoking, etc.
• OPENINGS - eyes, ears, nose, throat

19
CATEGORIES OF CHEMICALS

• IRRITANTS - a reversible inflammation
• CNS depressants - headaches, tremors, drowsiness,
  memory loss, irritability
• Target Organ Effect - liver, kidney, CNS, lung
• Carcinogen - IARC, NTP or 1 positive study
• Teratogen - causes birth defects
• Corrosive - irreversible damage to skin
• Asphyxiant - vapor or gas that displaces 02
• Flammable - flash pt. Under 100 degrees F

20
SYNERGISTIC EFFECT

• TWO CHEMICALS COMBINED TO PRODUCE A LARGER EFFECT
  THAN EXPECTED
• 1 2 5
• Asbestos and smoking
• Solvent use and alcohol

21
REACTIVITY DATA

• STABLE/UNSTABLE
• HAZARDOUS POLYERIZATION
• INCOMPATIBILITY (MATERIALS TO AVOID)
• HAZARDOUS DECOMPOSITION PRODUCTS
• PROPER STORAGE OF THE MATERIAL

22
PERSONAL PROTECTIVE EQUIPMENT

• Eye wear - glasses, goggles, shield - ANSI
• Gloves - match the use
• No shorts, open-toed shoes, long hair, ties
• Shoes - resistant, steel-toed
• Using engineering controls when possible

23
LABELING WARNINGS

• Hazardous Material Identification System or HMIS
• National Fire Protection Association - NFPA
• Emergency Response Guide UN s used for
  transportation incidents, large containers
• Use original container or proper labeling
• Target organs if appropriate

26
EMERGENCY RESPONSE /SPILLS

• MSDS DOESNT TELL YOU MUCH
• MATCH SPILL CLEANUP MATERIALS WITH USE
• KEEP PEOPLE OUT OF THE AREA/SPILL
• INFORMATION ABOUT THE CHEMICAL
• DONT BECOME PART OF THE PROBLEM
• EVACUATE IF NECESSARY
• Call X2005 during the day if theres a problem
• CALL X2222, University Police, after hours.

27
