Hazard Communication Program Employee Training Module
Training Program • Right-to-Know Law or HazCom Standard is designed to present you with information and training in the use and hazards associated with hazardous chemicals and substances. • How to read and interpret container labels and Material Safety Data Sheets (MSDS). • Recognize hazards and take the appropriate precautions. • The chemistry of Hazardous Materials. • Where to obtain specific information.
Scope and Application This program applies to all employees of who may be exposed to hazardous chemicals in a manner inconsistent with normal consumer use. The HazCom Program provides you with the necessary information and resources needed to ensure you are aware of the hazards associated with hazardous materials located and/or used within your work place. Elements of this program are designed to communicate to employees all safety related information about hazardous chemicals used in their work environment. Knowledge of hazardous materials is key to preventing over exposures, work-related illnesses, and chemical accidents.
Century Fence Policy POLICY • To provide a safe and healthy work place • Make information readily available to employees • Provide training for all affected employees • Implement appropriate workplace controls, practices and procedures • Minimize threat to employee safety & health • Require less toxic/hazardous substitutes be used • Prevent unauthorized introduction of chemicals into the workplace by requiring pre-approval • Support safety engineer in program implementation
OSHA Requirements • Location & availability of documents • Written HazCom program • Material safety data sheets • Hazardous chemicals list • Location of hazardous materials • Exposure data where available • Medical files • Methods & observations to detect releases • Labeling systems • Physical & health hazards of chemicals • Protective measures you can take

Non-Routine Tasks & Piping Systems • HazOp review must be performed prior to performance of any non-routine task. • Non-routine tasks are identified as anything you don’t normally do. Includes employees and contractors. • HazOps ensure all hazards relating to a specific task or project are properly identified and communicated to protect employee and contractor health and safety. • Piping systems are labeled and/or color coded in areas readily accessible to employees. • Fuel lines - yellowWater lines - greenFire sprinklers - red • Buried piping or runs near ceiling may not be labeled. • Consult supervisor before work.
Contractor Provisions • Contractors are afforded the same rights as employees • HazOp reviews must be held prior to work • Must be informed of task and hazards involving hazardous chemicals • Made familiar with company emergency procedures • Must supply company with list of hazardous substances contractor will be using on premises • Notices must be put up in work area where appropriate • Example: Power spray washing with cleaner • Example: Sandblasting • Example: Painting

MSDS Material Safety Data SheetsTHE KEY TO CHEMICAL HAZARD INFORMATION • MSDS must be on file for all hazardous materials before allowed into use. • New substances must be pre-approved for use. • New uses of approved substances should be approved.
Hazardous Chemical Locations • Hazardous Chemical List For Facility • Consult MSDS Index for complete listing of all hazardous chemicals and location • Drums • Processes • Storage tanks (ammonia, propane, nitrogen, helium, sulfuric acid, oil)
Chemical Use • Know the hazards before use • Wear the appropriate PPE when handling (e.g. gloves, acid suit, face shield for acid transfers) • Ensure appropriate controls are functioning (e.g. exhaust hood is on when present) • Use the substance in a manner consistent with its labeling. • Treat all chemicals with respect. • Never use a chemical unless you know the hazards associated with its use and the protective measures to be taken.
Detecting Releases • Company conducts monitoring when conditions warrant. May be done in-house or by outside consultant depending on circumstances • Unusual work area conditions should be communicated to supervisor or safety engineer immediately POSSIBLE RELEASE INDICATORS • Unusual odors • Smoke or visible haze • Abnormally high absenteeism rate • Employees sick more than normal • Dead or dying plants, vegetation or local animals • Neighborhood complaints • Unusual smell from sewers • Sound of escaping gas or steam
Detecting Releases • Physical Changes Noted In Your Body or Behavior May Also Signal Exposure or Over-Exposure to a Hazardous Substance and You Should Seek Medical Attention if • Unusual Taste In Mouth or Discolored Tongue or Lips • Skin or Eye Irritation or Rash • Difficulty Breathing, Seeing or Hearing • Mucous Membrane, Respiratory or Urinary Tract Irritation • Swelling of Extremities or Loss of Weight • Abnormal Behavior, Dizziness, Fainting • Uncontrollable Shaking or Shivering • Burning Sensation in Nose, Eyes or Throat • Loss of Weight or Hair • Any Abnormal Health Conditions
Protective Measures You Can Take • Follow all safety rules and policies • Use laboratory ventilation hoods when working with chemicals • Read the MSDS before using chemical • Ground flammable liquid containers when transferring to another container • Wear appropriate personal protective equipment • Report unusual & unsafe conditions/acts • Don’t do anything you feel is unsafe, talk with you supervisor • Seek out information on chemicals • Request additional safety equipment when PPE is worn out or unusable • Know location of safety showers, exits, and eyewashes • Identify piping systems before working on it • Never use any chemical from an unlabeled container • Always replace lid on container • Don’t accept sales samples without approval

Health & Toxicology Two Types of Health Affects: • Acute: Short-Term effects on body. Symptoms develop immediately or shortly after exposure. Effect is usually of short duration. • Chronic: Long-Term effects on body resulting from repeated low level exposures with symptoms developing slowly over a period of time. • Examples: Drunkenness is the acute effect from overindulgence in alcohol. Liver & brain damage are chronic affects. • Smoking: Acute = Wheezing, Shortness of Breath Chronic = Lung Cancer, Emphysema
Exposure Limits Developed to protect you from adverse health effects, both acute and chronic. Two main types: • PEL: Permissible Exposure Limits determined by OSHA for which the majority of persons can be exposed to for 8 hours a day, 40 hours a week, without experiencing any adverse health effects. See OSHA Z-Tables. • TLV: Threshold Limit Values established by the American Conference of Governmental Industrial Hygienists (ACGIH). Recommended Exposure Limits. PELs take precedent over TLVs. • Both types usually expressed as concentration or mass per unit volume (ug/m3). • PELs have ceiling limits - Can Not Exceed Ever • TLVs and PELs have STELs - 15 minute Short Term Exposure Limits • Use MSDS recommendations in absence of PEL/TLV
Toxic Effects Based on Actual Case Studies and Animal Experiments That Are Extrapolated to Infer Expected Effects on Humans • LD50: Lethal Dose of chemical substance in which 50% of the test animals are expected to die from oral, dermal, or absorption routes of exposure. Expressed in milligrams per kilograms of the animal tested. • LC50: Lethal Concentration of chemical substance in which 50% of the test animals are expected to die from exposure to airborne concentrations. Expressed in units of weight, milligrams or micrograms, per volume of air, usually cubic meters and specifies time period, usually 1 or 4 hours.
Toxic Effects • Corrosive: Liquid or solid that causes visible destruction or irreversible alterations in human tissue. Usually thought of as a Physical Hazard. • Examples: Acids, Flux, Caustics, Hydroxides, Ammonia • Irritant: Inflammatory response of eye, skin or respiratory system • Examples: Smoke, Dusts, Almost all Chemical Vapors • Sensitizer: Can become sensitized after just one exposure if you are susceptible. Skin sensitization is most common form. • Examples: Isocyanates used in Plastics and Resins • Neurotoxin: Capable of causing neurological damage to the central nervous system, usually only after long-term over exposures. • Examples: Many Solvents
Toxic Effects • Teratogen: Of concern to women. Compound or agent capable of causing malformations of fetus’ skeleton and soft tissues. • Examples: Mercury/Cerebral Palsy; Lead; PCBs • Mutagen: Compound or agent capable of causing genetic and chromosomal damage resulting in mutations capable of being passed on from generation to generation. • Examples: Lead; Ionizing Radiation; Ultra-Violet Light • Carcinogen: Compound or agent capable of causing cancer. • Example: Benzene (Component of gasoline) • Example: Cadmium Metal Fumes (Lead is a suspected carcinogen) • Example: Formaldehyde
