6Your Potential Workplace Exposure

First Aid Responder

Janitorial Duties7First AidFirst aid trainingGood SamaritanCollateral duty*Designated responder Not covered by BBP StandardBBP standard applies

* if First-Aid response is an expected part of the jobBBP standard applies1/10/2010Rev. April, 1997Page 8Do the BBP requirements apply to first aid trained individuals?The answer depends on the employers expectation of that employees application of 1st aid in the course of their job.As you may know, all employers must have 1st aid trained employees at their workplaces.Handout: WRD 11.45, 1st aid certification & BBP requirements.Good Samaritan: If employers have a distinct policy of 1st aid treatment that is only offered on a voluntary basis by the trained individuals, these actions may be classified as Good Samaritan. The BBP standards do not apply only under these circumstances. BBP issues and some training would be required under APP.Collateral Duty: The employer made it part of the job duty for an employee to provide 1st aid, but the actual event would be rare. All elements of the BBP standard apply, but HBV vaccinations may be delayed until the first time there is a 1st aid incident involving blood or OPIM (regardless of whether there is an exposure incident). See WRD 92-6, corrective amendment.Designated Responder: The employer makes 1st aid part of the job duty for an employee and exposure would be anticipated. All elements of BBP standard apply.HEPATITIS AAcquired primarily through the fecal-oral route.Causes an infection of the liver.Cannot be distinguished from other forms of Hepatitis without testing.The restaurant hepatitis.

9HEPATITIS BContracted from contact with blood or other bodily fluids.100 times more contagious than Human Immunodeficiency Virus (HIV). Can live in a dry environment for at least 7 daysSome people can be carriers and never get sick, but they can infect others.There is no cure, but there is a preventative vaccine.

10Hepatitis BVery infectious 1/3 no symptoms, 1/3 flu-like, 1/3 severe 6 to 10% of cases infectious for life (carrier state)In the past, 140,000-300,000 new infections per year 5,000-6,000 deaths/yr from chronic liver disease

11HEPATITIS CSpread by infected blood or other bodily fluids. Once contracted, over 70% of cases become chronic.No preventative vaccine.Current risk rate of contraction is 1 in 10,000.12HEPATITIS C4 million Americans infectedOnly 25% of those infected have been diagnosedCarrier state can develop with or without symptomsCarrier state can lead to chronic liver disease, cirrhosis (10 year latency), or cancer (alcohol is strong co-factor)Leading cause of liver transplant in U.S.

13HEPATITIS CSigns and symptoms may not appear until 10 years after infectionOnset of symptoms may present with severe liver diseaseNo broadly effective treatmentNo vaccine available

14HEPATITIS- A,B,&CHeating foods above 1800 F for one minute will kill the virus.Good hygiene (washing hands and face) is the best prevention method.A 10% bleach solution if also an excellent disinfectant.15Signs and Symptoms of HepatitisFlu-like fatigue and loss of appetiteFever, nausea, and joint painHeadachesJaundiceDark colored urineLight colored stool

16Hepatitis B Infected Liver

NormalHepatitis B17Human Immunodeficiency Virus (HIV)Spread by exchange of blood or other bodily fluids.Attacks the bodys immune system.Can live in a dry environment for only a few hours

18Human Immunodeficiency Virus (HIV)> 1 million infections in U.S.138 cases of possible occupational transmission

Infected persons may be asymptomatic for years.Usually develops into Acquired Immunodeficiency Syndrome (AIDS)

19Signs and Symptoms ofHIV and AIDSAfter infection a person will experience flu-like symptoms, then they may become asymptomatic for years.When symptoms do appear they are usually in the form of weight loss, fatigue, night sweats and fever.As the disease progresses the infected person usually dies from an opportunistic infection or cancer due to their weakened immune system.20How Do You Protect Yourself?Exposure Control PlanUse the Universal PrecautionWork Practice ControlsEngineering ControlsPersonal Protective Equipment

21Exposure Control PlanHepatitis B vaccinationPost exposure evaluation & follow-upCommunication and trainingRecordkeeping

22UNIVERSAL PRECAUTIONTreat all potentially infectious material as if it contained bloodborne pathogens!

23Work Practice ControlsControls that reduce the likelihood of exposure by altering how a task is performed.Examples:Washing hands after coming into contact with potentially infectious materials.Not eating, drinking, or smoking in areas where potentially infectious materials are located.Decontaminating work surfaces after use.24HousekeepingMaintain a clean and sanitary workplaceWritten cleaning and decontamination scheduleContaminated waste disposal methodsLaundry

1/10/2010Rev. April, 1997Page 25The employer has to ensure that the worksite is maintained in a clean and sanitary condition.An appropriate written schedule for cleaning and decontamination must be developed for the program.The written procedures has to include individual locations, how often, what specific cleaners and disinfectants are used and the specific cleaning procedures.The disinfectant must be an EPA approved tuberculocidal or HIV/HBV effective disinfectant. The label on the product will have this information. Check with distributors or EPA maintains a listing of the products.A dilution of household bleach to water of between 1:10 to 1:100 may be used. It should be made daily, older solutions lose potency. Engineering ControlsControls that reduce employee exposure by either removing the hazard, or by isolating the employee.Examples:Using a dust pan or tongs to pick up broken glass.Using biohazard disposal containers to dispose of potentially infectious materials.

28PPE GlovesLatexNitrile VinylUtility

1/10/2010Rev. April, 1997Page 29Gloves must be carefully selected for their intended use. Important considerations are permeability to microorganisms, dexterity and durability. Gloves must be frequently changed because the will develop pinhole leaks that are not visible but can allow passage of microscopic organisms.Pictured above is a dispensing rack with gloves of different size. It is important that the glove are located where they are used.Latex gloves are strong allergic sensitizers. It is estimated that up to 8-12% of the users of latex gloves will develop an allergic dermatitis reaction. Some may even have stronger respiratory allergic reactions. Substitute materials must be found to accommodate sensitized individuals. Common substitute materials are nitrile and vinyl. If using latex, chose powderless and those with low-protein or antigen contentThicker utility gloves are needed for tougher jobs where more abrasion is encountered. These gloves must be changed before they start to show wear. They must be disinfected in between uses.Vaccinations

The Hepatitis vaccination is given as a series of three injections, whose schedule will be determined by a doctor.

The Hepatitis B vaccine prevents Hepatitis B in 85 95% of the people who get all three shots.

30Hepatitis B VaccinationMake Hepatitis B vaccination available Declination statement requiredAvailable at later date if desiredNo cost to employeesReasonable time and placeIf series is interrupted, continue at any time rather than restart series1/10/2010Rev. April, 1997Page 31All employees with occupational exposure must be offered the vaccinationEmployees have the right to refuse the vaccination, but must sign the declination form in Appendix A. They may change their mind at any time in the future.RecordkeepingMedical recordsHBV vaccination statusWritten medical opinion of exposure incidentsExposure incident detailsMaintain for length of employment + 30 years

1/10/2010Rev. April, 1997Page 32Medical records that are maintained by the employer may not contain any confidential medical information. The only exception is the HBV vaccination status of the employee. The employer can make arrangements with a healthcare provider to maintain medical recordsA disease that is attained through an exposure incident must be documented on the OSHA 200 log.If 10 or less employees, a record of injuries must be kept even if the OSHA
