Hazardous Chemicals can pose a Health Hazard
Acute health hazards cause adverse health effects immediately or soon after the exposure
Usually occur from a short term, high dose exposure
Chronic health hazards cause adverse health effects after years of multiple low dose exposure
They may cause measureable adverse changes in the body:
Sensitizers: cause an allergic skin or lung reaction Latex, chlorinated hydrocarbons
Carcinogens: may cause cancer. formaldehyde, methylene chloride
Toxic & highly toxic agents: may cause adverse effects at low doses
Irritants: cause redness and swelling of the skin, eyes, respiratory tract acid gases, aromatic hydrocarbons
Hazardous Chemicals can pose a Health Hazard
Corrosives: cause tissue damage and burns on contact with skin and eyes hydrofluoric acid
Teratogens: may cause birth defects Organ Specific Hazards: may cause
damage to specific organ systems such as the blood, liver, lungs, reproductive system
Hazardous Chemicals can pose a Health Hazard
Hazardous Chemicals can pose a Physical Hazard
They have a potential to cause harm because they are:
Fire Hazards–Combustible liquids–Flammable liquids–Flammable aerosols–Flammable gases–Flammable solids–Oxidizers–Pyrophorics
Explosion Hazards–Compressed gases–Explosives
Reactive Hazards–Organic peroxides–Unstable (reactives)–Water-reactives
Routes of Exposure to Chemical Hazards
Inhalation of dusts, fumes, mists, and vapors
Skin absorption
Ingestion of contaminated food and beverages through poor work habits
Injection-usually associated with BBP
Exposure Considerations Maintain concentrations of airborne
contaminants as low as practical below established exposure limits
Most regulatory limits are maintained with a properly functioning fume hood
Single digit and fractional exposure limits may require greater controls
EH&S can conduct personal exposure monitoring to determine exposure levels
Examples of OSHA’s Personal Exposure Limits (in ppm)
acetonitrile 40
benzene 1 (0.5 action) (5 STEL)
chloroform 50 (ceiling)
formaldehyde 0.75 (0.5 action) (2 STEL)
methanol 200
methylene chloride 25 (12.5 action) (125 STEL)
pyridine 5
Hazard Identification
Safety Data Sheets, previously known as Material Safety Data Sheets
A tool prepared by the manufacturer or importer outlining:– Physical and chemical characteristics– Health and physical hazard information– Control measures– Emergency, first aid, and spill procedures– Protective exposure limit(s)
SDS: What is my responsibility? Update your chemical inventory annually Obtain a SDS for each hazardous material
before it is used Ensure the SDS file is readily accessible
to employees when they are in their work areas
Chemical inventory lists and SDS’s are exposure records, maintain either/both for 30 years after employment
Uniform Safety Data Sheet (SDS) format
effective June 1, 2015
Section 1, Identification includes product identifier;manufacturer or distributor name, address, phonenumber; emergency phone number; recommended use;restrictions on use.Section 2, Hazard(s) identification includes all hazardsregarding the chemical; required label elements.Section 3, Composition/information on ingredientsincludes information on chemical ingredients; trade secretclaims.Section 4, First-aid measures includes important symptoms/effects, acute, delayed; required treatment.Section 5, Fire-fighting measures lists suitable extinguishingtechniques, equipment; chemical hazards from fire.Section 6, Accidental release measures lists emergencyprocedures; protective equipment; proper methods ofcontainment and cleanup.Section 7, Handling and storage lists precautions for safehandling and storage, including incompatibilities.

Controlling Exposures
Elimination or Substitution
Eliminate the use of hazardous materials when possible
Substitute with less hazardous materials, equipment, and processes– Use ordinary detergents or enzymatic cleaners
instead of dichromate/sulfuric acid mixtures– Use digital or alcohol thermometers instead of
mercury thermometers
Reduce the quantities you purchase/use
Use Engineering Controls
Initial design specifications
Change the process
Physically change the machine or workenvironment to prevent exposures
Enclose the process
Isolate the process Use ventilation
Tips for Effectively Using Fume Hoods Keep your lab doors closed Adjust the sash to the lowest level for
convenient use Work at least six inches inside the face of the
cabinet Keep the hood free of clutter, avoid use as
chemical storage Avoid heating perchloric acid in regular fume
hoods Place materials along the side panels, avoid
placement in front of rear slots
Wash your hands
Do not prepare, store, or consume food or beverages where hazardous chemicals are used or stored
Secure compressed gas cylinders
Store flammables in an approved cabinets
Regularly inspect and test peroxide-formers
Segregate stored chemicals by hazard class
Use secondary containment to transport chemicals
Shield equipment from fire and explosion hazards
Incorporate Good Hygiene and Work Practices
Anticipate exposuresWear personal protective equipment
PPE is used if other controls cannot provide adequate protection
The minimum PPE that should be worn while handling chemicals:– Gloves– Safety glasses/goggles– Lab coat
Anticipate exposuresWear personal protective equipment
Select chemical-resistant gloves based on the hazard. Avoid latex gloves!
Have your lab coat professionally laundered.
Ensure your eyewash is always accessible.
Contact EH&S if you are concerned about needing respiratory protection
Avoid respirators for routine lab work
Before wearing a respirator, you must:– Participate in additional training– Complete a medical evaluation– Receive a fit test
Dispose of Hazardous Chemical Waste Follow the procedures outlined in
Advisory 7.3: Management of Chemical Wastes– Complete a waste label– Ensure waste is secure and store in an accessible area
Never drain dispose of hazardous chemicals Avoid storing hazardous waste on the floor Triple rinse acute hazardous waste (P-list)
containers before placing them in the dumpster, dispose of the rinsate as waste
Label empty containers with the word “EMPTY” and take to the dumpster
Emergency Preparedness
Emergency equipmentMinimizes injury should your
initial controls fail
Exits & fire extinguishersEyewashesEmergency showersElectric panels

Expect spills to occur
Take action to clean up
chemical andbiological spills
immediately
Contact EH&S if you need assistance
Dispose of spill clean-up materials as hazardous waste
Expect spills to occur
Prepare your
spill kitbefore anincidentoccurs
Chemicals stored on floor createtripping hazards and increase the chance of a chemical spill
Identify the improper practice
Missing or damaged labels cause identification problems
Identify the improper practice
No label and the removed tip compromises the container’s integrity
Uncapped and unsecured
waste bottle increases the potential for spills and exposures
Unsecured gas cylinders can be knocked over, improperly stored PPE can become contaminated
Identify the improper practice
Open and unsecured waste container, blocked eyewash, electrical extension cords fed under door, housekeeping and tripping hazards
Identify the improper practice
Contaminated work surfaces, excessive storage impedes air flow, the fume hood sash is open greater than 18 inches
Identify the improper practice
About Nanotechnology. . .Engineered structures, devices, and systems
that have a length scale between 1 and 100 nanometers
Remain suspended for days to weeks if released into the air
Routes of exposure include inhalation, ingestion, and skin penetration
Some nanoparticles can enter the brain directly by means of the olfactory pathway from the nose
Source enclosure and local exhaust ventilation are currently accepted controls
Strategies to control exposure to nanoparticles
Total enclosure of the process
Partial enclosure with local exhaust ventilation
Limiting the number of workers and exclusion of others
Use of suitable PPEReduction in periods
of exposureRegular cleaning of
walls and surfacesProhibition of
eating/drinking in contaminated areas
