Certain toxins are produced by specific pathogenic microorganisms and are the causative agents in various diseases, as tetanus, diphtheria, etc. TOXICITY - The effect a specific quantity or dosage of a specific toxin (Chemical) has on a living microorganism. This is not an absolute! HAZWOPER - SLIDE 75 OF 184 © Copyright Compliware 1999 TOXICITY INGESTION Swallowing of a substance through the mouth and into the stomach. Generally followed by its entrance into the small intestine. ABSORPTION Entering the body through the skin. Substances that absorb through the skin sometime further assimilate into the blood system. INHALATION Breathing causes us to inhale substances which in return travels en route to the lungs. Our lungs are so rich in blood vessels that any substance inhaled into the lungs are readily absorbed into the bloodstream. HAZWOPER - SLIDE 76 OF 184 © Copyright Compliware 1999 TOXIC EFFECTS ACUTE - Is generally regarded as a severe injury caused by a one time, relatively short exposure to a chemical substances harmful to the human body. CHRONIC - Is an injury or disease that manifests itself after a relatively long period of time has elapsed since the initial exposure to the substance causing some type of ailment. - Is an injury or disease that remains undeveloped until an incubation period has elapsed. The period of time could be hours, days, months or years. LATENT IRRITANT - Is a chemical substance that injures the tissues of the respiratory system and lungs, thereby causing inflammation of the respiratory passages.

IDLH levels are published for many substances by OSHA and NIOSH. In practice, when the concentration of a toxic substance in a given area is known, IDLH levels may be used for determining whether self-contained breathing apparatus is needed when entering the area. If the concentration exceeds the IDLH level, positive- demand, self-contained breathing apparatus should be used. HAZWOPER - SLIDE 88 OF 184 © Copyright Compliware 1999 SUMMARY OF TLV TLV - Threshold Limit Value: One of three categories of chemical exposure levels - TLV-TWA, TLV-STEL or TLV-C. TLV-TWA - Threshold Limit Value Time-Weighted Average: The time weighted average concentration for a normal 8-hour workday and a 40 hour work week to which nearly all workers may be repeatedly exposed without adverse effect. Should be used as an exposure guide rather than an absolute. TLV-STEL - Threshold Limit Value - Short Term Exposure Limit: A 15 minute time-weighted average exposure that should not be exceeded at any time during the work day. TLV-C - Threshold Limit Value- Ceiling: The concentration that should not be exceeded even instantaneously.

Level A protection should be used when: The hazardous substance has been identified and requires the highest level of protection for skin, eyes and the respiratory system based on either the measured (or potential for) high concentration of atmospheric vapors, gases, or particulate; or the site operations and work functions involve a high potential for splash, immersion, or exposure to unexpected vapors, gases, or particulate of materials that are harmful to skin or capable of being absorbed through the skin. Substances with a high degree of hazard to the skin are known or suspected to be present, and skin contact is possible. Operations are being conducted in confined, poorly ventilated areas, and the absence of conditions requiring Level A have not yet been determined. HAZWOPER - SLIDE 125 OF 184 © Copyright Compliware 1999 LEVEL - B PROTECTION Level B is used when the highest level of respiratory protection is necessary but a lesser level of skin protection is needed. Level B protection should be used when: The type and atmospheric concentration of substances have been identified and require a high level of respiratory protection but less skin protection. The atmosphere contains less than 19.5 percent oxygen. The presence of incompletely identified vapors or gases is indicated by a direct reading organic vapor detection instrument, but vapors and gases are not suspected of containing high levels of chemicals harmful to skin or capable of being absorbed through the skin. NOTE: This involves atmospheres with IDLH (Immediately Dangerous to Life and Health) concentrations of specific substances that present severe inhalation hazards and that do not represent a severe skin hazard. HAZWOPER - SLIDE 126 OF 184 © Copyright Compliware 1999 LEVEL - C PROTECTION Level C is used when the concentration(s) and type(s) of airborne substance(s) is known and the criteria for using air purifying respirators are met. Level C protection should be used when: The atmospheric contaminants, liquid splashes, or other direct contact will not adversely affect or be absorbed through any exposed skin. The types of air contaminants have been identified, concentrations measured, and an air purifying respirator is available that can remove the contaminants. All criteria for the use of air purifying respirators are met. HAZWOPER - SLIDE 127 OF 184 © Copyright Compliware 1999 LEVEL - D PROTECTION Level D is used for nuisance contamination only.

You can not always see or smell the hazards, but dust, smoke, fog, mist, fumes, gases, vapors and sprays can be very hazardous to your health and safety. So, you need to ask yourself the following questions? 1. What are the exposure limits allowed for the particular contaminants? 2. Have the hazard levels in your work area been measured? 3. Do you have the correct amount of oxygen in your work area? 4. Are you trained to use and wear a Respirator? Remember - Respirators play a big part in your Safety. The actual properties of the hazard must be known to make a decision on the specific type of equipment to be used! HAZWOPER - SLIDE 147 OF 184 © Copyright Compliware 1999 Types of Respirators Air-purifying or Filtering - The APR is used where there is enough oxygen present ( approx. 20%), but the air in the area is contaminated with gases, vapors, and dust. These respirators filter out dangerous materials or diverts air through a chemical filter. WARNING - Some substances can not be safely filtered out requiring you to wear a Air - Supplied Respirator. HAZWOPER - SLIDE 148 OF 184 © Copyright Compliware 1999 Types of Respirators Supplied-Air Respirators - The SAR is used whenever there is not enough oxygen in a confined space or area and the concentration of the airborne substances present is immediately dangerous to life and health (IDLH). All respirators must be approved for the contaminant for which the employee is exposed too. Approval is done jointly by the Mine Safety and Health Administration of the Department of Labor and the National Institute for Occupational Safety and Health (NIOSH) of the Department of Health and Human Services. HAZWOPER - SLIDE 149 OF 184 © Copyright Compliware 1999 Types of Respirators Self - Contain Breathing Apparatus (SCBA) SCBA uses a source of breathable air carried by the wearer. Although this greatly enhances the mobility of the wearer it limits the duration of protection. At a moderate work rate, using approximately 40 liter minute volume, most SCBA used in hazardous situations have a rated duration of 30 to 60 minutes. SCBA consist of the following: Face piece, Breathing tube, Air supply tube, Regulator, Exhalation valve and Air Cylinder and valve. HAZWOPER - SLIDE 150 OF 184 © Copyright Compliware 1999 THE PHYSICAL REQUIREMENTS Respirators places a strain on the wearer’s cardiovascular system. All workers must exert a greater degree of effort to inhale and exhale when wearing a respirator. Some people are claustrophobic and cannot wear respirators. OSHA requires that anyone assigned a task requiring the use of respirators be examined and certified as being able to safely wear the respirator. Furthermore, the worker and supervisor must have a basic understanding of respirator selections, operations, fitting, limitations and maintenance. HAZWOPER - SLIDE 151 OF 184 © Copyright Compliware 1999 PROPER FITTING The proper fitting of a respirator is determined by a fit tests and seal checks. Fit tests can be “Qualitative” or “Quantitative”. Some OSHA Standards have specific requirements for fit testing. QUALITATIVE QUANTITATIVE Upon issue and semi-annually Irritant smoke or banana oil Recite “Rainbow” passage Subjective response Measure concentration inside mask Port drilled into mask Takes approximately 1 hour Requires expensive equipment and trained personnel Ensures correct fit for model HAZWOPER - SLIDE 152 OF 184 © Copyright Compliware 1999 R E S P I R A T O R Y C H E C K L I S T Do a fit test. Receive training. Provide proper care. Measure hazard levels. Receive a Medical test. Review exposure limits. Select correct Respirator. Receive Annual Physical. Receive Annual Training. Check the Oxygen levels. Provide proper maintenance. Look for signs of deterioration. Follow policies and procedures. Wear only approved respirators that you have received instruction. HAZWOPER - SLIDE 153 OF 184 © Copyright Compliware 1999 SPILL CONTROL HAZWOPER - SLIDE 154 OF 184 © Copyright Compliware 1999 Spill Control The control of any inadvertent release of hazardous materials can be as simple as turning off a valve, turning a drum on its side, to performing a complete day of clean-up in a totally encapsulating suit. HAZWOPER - SLIDE 155 OF 184 © Copyright Compliware 1999 CONTAINMENT Any procedures taken to keep the material in its original container, Contaminate activities are generally undertaken by a Hazardous Material Technician or Specialist and require many hours of training and practice. Your imagination is a good place to begin to develop containment methods. Super glue, underwater patching materials for boats and fast setting materials for casts are just some of the simple examples. HAZWOPER - SLIDE 156 OF 184 © Copyright Compliware 1999 CONFINEMENT Any procedures taken to keep all the material in a defined area. These activities will vary from plant to plant and will be determined by the company emergency response plan. Spills or releases can be confined by our A, B, C, D materials. Absorption Blocking Collection Diking HAZWOPER - SLIDE 157 OF 184 © Copyright Compliware 1999 A B S O R P T I O N Materials like dirt, sand, soda ash, saw dust, vermiculite, or even kitty litter can absorb the spill. The absorption material should be placed in front of the material with consideration of any slope or grade. A key note to remember, the absorption materials MUST be COMPATIBLE with the spilled material. HAZWOPER - SLIDE 158 OF 184 © Copyright Compliware 1999 B L O C K I N G Means the protection of drains, ditches, or storm sewers from run-off of any spilled material. These items should be blocked by dams, rubber covers, pillows, booms. HAZWOPER - SLIDE 159 OF 184 © Copyright Compliware 1999 C O L L E C T I O N The collection of these materials can be placed in approved DOT containers, or other types of containment for proper disposal. HAZWOPER - SLIDE 160 OF 184 © Copyright Compliware 1999 D I K I N G Diking materials like sand, earth, or other similar materials can be used to contain the perimeter of the leak. The material used for diking MUST also be COMPATIBLE with the spilled material. HAZWOPER - SLIDE 161 OF 184 © Copyright Compliware 1999 D E C O N T A M IN A T I ON HAZWOPER - SLIDE 162 OF 184 © Copyright Compliware 1999 DECONTAMINATION DECONTAMINATION is a very important part of Training. Emergency response workers at the First Responder, Operations Level, Hazardous Materials Technician, Hazardous Materials Specialist, and On-Scene Incident Commander levels are all required to know and understand decontamination procedures. HAZWOPER - SLIDE 163 OF 184 © Copyright Compliware 1999 DECONTAMINATION Contamination is derived from the Latin verb meaning “To Touch”, while the prefix De means “Do the opposite of.” So we can not stress this importantly enough, “Do Not Touch” these materials. TOUCH HAZWOPER - SLIDE 164 OF 184 © Copyright Compliware 1999 DECONTAMINATION Contamination at hazardous waste sites can occur to people, vehicles, equipment, buildings and to the environment, both plants and animals. By avoiding contamination through proper positioning of people, apparatus and equipment, you eliminate the need to decontaminate. Decontamination is performed whenever any the following conditions are present: When there is obvious contamination by a know substance. When there is suspected contamination by a know substance. When there is likelihood of exposure to a deadly substance. When you don’t want to spread the contamination. When you want to protect the environment. HAZWOPER - SLIDE 165 OF 184 © Copyright Compliware 1999 GOAL OF DECONTAMINATION Is to minimize the potential harm to people and the environment by eliminating or reducing the hazards of the chemical contaminant. HAZWOPER - SLIDE 166 OF 184 © Copyright Compliware 1999 METHODS OF DECONTAMINATION DILUTION ABSORPTION DEGRADATION ISOLATION NEUTRALIZATION DISPOSAL HAZWOPER - SLIDE 167 OF 184 © Copyright Compliware 1999 DILUTION THE THINNING OUT OR WEAKENING OF A SUBSTANCE BY ADDING ANOTHER MATERIAL, CALLED A DILUTENT. DILUTION IS A VALID STEP IN DECONTAMINATION, BUT THE END MATERIAL WILL STILL HAVE TO BE DISPOSED OF. HAZWOPER - SLIDE 168 OF 184 © Copyright Compliware 1999 ABSORPTION THE PROCESS WHERE ONE SUBSTANCE COMBINES WITH ANOTHER BY MOVING INTO IT OR ENTERING THE INTERIOR OF THE OTHER SUBSTANCE. WHEN ABSORBENT ARE USED IN THE DECONTAMINATION PROCESS, THE COMBINED MATERIAL MUST BE CONSIDERED AND HANDLED AS CONTAMINATED. HAZWOPER - SLIDE 169 OF 184 © Copyright Compliware 1999 DEGRADATION THE MOLECULAR BREAKDOWN OF A MATERIAL. IN THE CASE OF A CONTAMINANT IT CAN RENDER THE MATERIAL LESS HAZARDOUS. THE PROCESS CAN BE USED IN DECONTAMINATION, BUT THE EXTENT OF DEGRADATION MUST BE MONITORED AND VERIFIED. HAZWOPER - SLIDE 170 OF 184 © Copyright Compliware 1999 ISOLATION THE ESTABLISHMENT OF A BOUNDARY OR PERIMETER WHERE A MATERIAL IS LOCATED OR PLACED, AND WHERE ENTRY IS RESTRICTED TO UNAUTHORIZED PERSONNEL. ISOLATION IS NOT ALWAYS ACHIEVABLE OVER THE LONG TERM, BUT IT DOES PROVIDE A TEMPORARY METHOD OF DEALING WITH A CONTAMINATED SUBSTANCE. HAZWOPER - SLIDE 171 OF 184 © Copyright Compliware 1999 NEUTRALIZATION THE PROCESS THAT OCCURS WHEN ACID AND BASES NEUTRALIZE EACH OTHER; I.E. THE CHARACTERISTIC PROPERTIES OF BOTH ACID AND AND BASES DISAPPEAR OR HAVE A NEUTRAL VALUE. WHERE IT CAN BE ACHIEVED NEUTRALIZATION IS AN EFFECTIVE TECHNIQUE IN DECONTAMINATION. HAZWOPER - SLIDE 172 OF 184 © Copyright Compliware 1999 DISPOSAL THE FINAL STEP IN A PROCESS WHEREBY A SUBSTANCE IS TRANSFERRED TO AN AUTHORIZED PARTY, OR TO A FINAL RESTING PLACE. HAZWOPER - SLIDE 173 OF 184 © Copyright Compliware 1999 LEVEL 1 DECONTAMINATION 3 LEVELS OF DECON Used when the nature of the incident indicates that there is at least a possibility that an exposure has occurred but no one is certain that it has. An example would be if a reconnaissance team entered a waste site, in appropriate clothing and SCBA, to identify the markings on a leaking 55 gallon drum. HAZWOPER - SLIDE 174 OF 184 © Copyright Compliware 1999 LEVEL 2 DECONTAMINATION 3 LEVELS OF DECON Used when you can physically see that contamination of clothing has occurred, but the skin has not been exposed. An example would be a drum is rolled over and you step in the spilled liquid. No one on the team experiences skin contact. HAZWOPER - SLIDE 175 OF 184 © Copyright Compliware 1999 LEVEL 3 DECONTAMINATION 3 LEVELS OF DECON Used whenever the chemical has come into contact with the skin. An example would be a member of the team is splashed by the liquid and the liquid has eaten a small hole in the clothing and is burning the skin. HAZWOPER - SLIDE 176 OF 184 © Copyright Compliware 1999 DECONTAMINATION CORRIDOR CRITERIA Topography - The decon corridor should be located on a level surface, upwind and upgrade from the site. Distance from spills - A minimum of 100 feet shall be maintained between the decon area and the spill for minor incidents. 500 feet for major incidents. Perimeters - An inner and outer security perimeter will be established. The entrance into the hot zone must be a controlled access point. Markings - Use stakes or cones and brightly colored perimeter tape to clearly identify the decon corridor. HAZWOPER - SLIDE 177 OF 184 © Copyright Compliware 1999 TIPS FOR USING CONTRACTORS REMEMBER, YOU CONTROL YOUR FACILITY OR AREA! REVIEW THEIR PROCEDURES WITH THEM BEFORE STARTING THE JOB! DETERMINE THEIR SAFETY PERFORMANCE RECORD! DETERMINE WHO IS IN CHARGE OF THEIR PEOPLE! DETERMINE HOW THEY WILL AFFECT YOUR EMPLOYEES! HAZWOPER - SLIDE 178 OF 184 © Copyright Compliware 1999 OSHA'S PERCEPTION OF A SUCCESSFUL PROGRAM 1. DETAILED WRITTEN HAZARD ASSESSMENTS 2. DETAILED WRITTEN SAFETY PROCEDURES 3. EXTENSIVE EMPLOYEE TRAINING PROGRAMS 4. PERIODIC REINFORCEMENT OF TRAINING 5. SUFFICIENT DISCIPLINE REGARDING IMPLEMENTATION 6. FOLLOW-UP HAZWOPER - SLIDE 179 OF 184 © Copyright Compliware 1999 WORK AT WORKING SAFELY Training is the key to success in managing safety in the work environment. Attitude is also a key factor in maintaining a safe workplace. Safety is, and always will be a team effort, safety starts with each individual employee and concludes with everyone leaving at the end of the day to rejoin their families. Patricia A.
