Right To Know 12 NYCRR PART 820

Hazard Communication 29 CFR 1910.1200

Purpose To protect employees from chemical hazards in the work place Right to know training must cover the following: Hazardous chemical(s) the worker is/or may be exposed to during normal use or in a foreseeable emergency. Where the chemical is present Effects that chemicals can have on the body Detection Methods Protection Safety Data Sheets (SDS)

What is a Hazardous Chemical? Any chemical which poses a physical or health hazard This can include: Common household cleaning agents Items that are not harmful in small doses, but can become lethal in large doses (think medications) Chemicals that are produced as a byproduct of combustion (carbon monoxide, carbon dioxide, various carcinogens) Chemicals found in research labs Chemicals associate with maintenance and operations (less likely) chemicals transported through our campus over public roadways

Common Household Cleaners Items containing Ammonia Items containing Bleach Items containing phosphorous All of these are commonly found in household cleaners, though the quantities may be smaller in the household than what one might expect to see in an industrial setting with a wide ranging custodial department Because housekeeping purchases chemicals in bulk, they are usually transferred to smaller spray bottles These must be labelled in accordance to 29 CFR 1910.1200 (part of this training will explain what those symbols mean)

CO and CO 2 Carbon Monoxide (CO) is an odorless and colorless poisonous gas that is a biproduct of combustion This can be found in close proximity to malfunctioning heaters (combustion style only) This can be a hazard in motor vehicles This can only be detected with special equipment The first signs of CO poisoning is drowsiness followed by headache nausea and eventual loss of consciousness The dangers of CO poisoning are especially high in the winter when people are prone to sitting in a running car, or combustion style space heater The same dangers apply to CO 2, Although, carbon Dioxide is also a product of respiration, so it can happen without combustion

Research Labs There are many chemicals in the various research laboratories A complete list is currently being generated. It is fair to assume that all chemicals in the research abs are hazardous The research labs are placarded per NFPA 704 standards (more on that later)

Department of Transportation The DOT mandates how shipments of hazards are to be labeled. It is possible, since there are public roads that cross through campus, that at some point hazardous materials may come through here that are not associated with the campus In this case it is vital to understand the DOT transportation symbols for hazardous materials.

Where are the Hazardous Chemicals? Those associated with the Schools of Science are stored in 5 locations throughout campus The volatile storage locker in the service drive of Physical Science The hazardous material storage room inside of Physical Science The Chemical inventory room on the second floor of Physical Science The Chemical prep room on the second floor of physical science The volatile storage room outside of Perna Science These are very hazardous, these should not be interacted with unless additional training on the subject has been received Excepting for an emergency where it is necessary to pull someone from these areas to safety

Where are the Hazardous Chemicals? Custodial Chemicals are found everywhere on the campus in varying amounts. The main stores of these are in the Human ecology building

Physical Hazards Combustible liquids and flammables Compressed gas containing cylinders Explosives (not stored on campus, but may be passing through) Oxidizers Pyrophorics Reactives

What is the difference between a combustible and a flammable material? First we need to know what a flashpoint is: Flashpoint: the temperature at which a particular organic compound gives off sufficient vapor to ignite in air. Flammable Liquid a liquid with a flashpoint less than 100 Fahrenheit (gasoline) Combustible Liquid a liquid with a flashpoint equal or greater than 100 F but less than 200 F (diesel fuel)

Compressed Gas Cylinders Rooms on campus where these can be found are placarded with this sign The main danger here is explosive decompression if a cylinder is damaged In the case of cylinders with flammable contents there is an explosion danger In the case of inert gasses the main dangers are frostbite and asphyxiation A ruptured cylinder containing oxygen would cause a fire to burn much more intensly

Explosives There are no explosives stored on campus, but since we have public roads, it is not unthinkable that a truck carrying them may be in your jurisdiction There are many different DOT classifications for these All DOT placards for explosives are orange. If you see one on an over turned truck do not approach

Oxidizers This is a substance that has the ability to provide oxygen for another substance This means that an oxidizer in the presence of a fuel source only needs a source of ignition to start combustion This also means that a fire involving an oxidizer cannot be extinguished by starving it of oxygen

Pyrophoric A material so unstable it may spontaneously combust in air at or below 130 Fahrenheit. Examples: Lithium Metal White or Yellow Phosphorous Potassium Metal Sodium Metal Where you are likely to encounter it here? Inside of lithium ion or lithium polymer (lion or lipo) batteries. This is why it is important to not puncture these

Reactive Reactivity is the tendency of a substance to undergo chemical reaction, either by itself or with other materials, and to release energy. Ammonia and Bleach are separately dangerous, but when combined they result in the release of chlorine gas which is deadly Chemical reactions can be more dangerous than the sum of their parts This is called synergy.

Health Hazards Acute Effects appear promptly after exposure, usually within 24 hours. Chronic Coughing Dizziness Vomiting Loss of Consciousness Death Delayed effects following repeated, long duration exposure Asbestosis fibrosis of the lungs caused by long term exposure to asbestos fibers Mesothelioma cancer of the pleura

Types of Chemical Health Hazards Carcinogens (Chronic) Toxic Agents (Acute and/or Chronic) Reproductive Toxins (Chronic) Corrosives (Acute) Irritants (Acute) Sensitizers (Chronic) Prolonged and/or continued exposure to acute hazards may develop into chronic conditions

Toxicity The ability of a substance to cause injury to living tissues Neurotoxin Hepatotoxin Nephrotoxin Cardiotoxin

Routes of Exposure Inhalation Ingestion Absorption Injection

Dose Response Concept The effect of a chemical depends on the amount and duration of the exposure to it A substance could be helpful in small doses (pharmaceutical) but deadly in larger doses. Likewise a short exposure to a toxin may not cause a lasting effect, but if that exposure is extended, the effect may be deadly (carbon monoxide)

Detection Many hazards are not detectable using human senses alone Thus the necessity to placard Certain dangerous storage areas have built in detectors CO monitors near furnaces Oxygen sensors near cryogenic storage For those hazards that are detectable using human senses the most trustworthy is the nose

Protection is achieved through a Hierarchy of Controls 1. Engineering Controls Substitution, Elimination, Ventilation, Enclosure 2. Administrative Controls- Work Practices, Employee rotation, Access Control, Education 3. Personal Protective Equipment- Last resort, Hazard still exists. (Last Resort but FIRST Response)

So how do you know if a Chemical is Hazardous? Safety Data Sheets (SDS) All hazardous materials have an SDS All Hazardous materials on campus have an SDS available both in a binder where it is stored and/or used, and also available online on our website: http://www.oneonta.edu/facilities/msds.asp
