§1904.6that the two injuries or illnesses are unrelated events,and that each represents an injury or illness thatmust be separately evaluated for its recordability.However, it is sometimes difficult to determinewhether signs or symptoms are due to a new eventor exposure, or are a continuance of an injury or illnessthat has already been recorded. This is animportant distinction, because a new injury or illnessrequires the employer to make a new entry on the<strong>OSHA</strong> 300 Log, while a continuation of an old recordedcase requires, at most, an updating of the originalentry. Section 1904.6 of the final rule being publishedtoday explains what employers must do to determinewhether or not an injury or illness is a new casefor recordkeeping purposes.The basic requirement at Section 1904.6(a) statesthat the employer must consider an injury or illness anew case to be evaluated for recordability if (1) theemployee has not previously experienced a recordedinjury or illness of the same type that affects thesame part of the body, or (2) the employee previouslyexperienced a recorded injury or illness of thesame type that affected the same part of the bodybut had recovered completely (all signs and symptomsof the previous injury or illness had disappeared)and an event or exposure in the work environmentcaused the injury or illness, or its signs orsymptoms, to reappear.The implementation question at Section1904.6(b)(1) addresses chronic work-related casesthat have already been recorded once and distinguishesbetween those conditions that will progresseven in the absence of workplace exposure andthose that are triggered by events in the workplace.There are some conditions that will progress even inthe absence of further exposure, such as some occupationalcancers, advanced asbestosis, tuberculosisdisease, advanced byssinosis, advanced silicosis, etc.These conditions are chronic; once the disease iscontracted it may never be cured or completelyresolved, and therefore the case is never “closed”under the <strong>OSHA</strong> recordkeeping system, even thoughthe signs and symptoms of the condition may alternatebetween remission and active disease.However, there are other chronic work-related illnessconditions, such as occupational asthma, reactiveairways dysfunction syndrome (RADs), and sensitization(contact) dermatitis, that recur if the ill individualis exposed to the agent (or agents, in the caseof cross-reactivities or RADs) that triggers the illnessagain. It is typical, but not always the case, for individualswith these conditions to be symptom-free ifexposure to the sensitizing or precipitating agentdoes not occur.The final rule provides, at paragraph (b)(1), thatthe employer is not required to record as a new casea previously recorded case of chronic work-related illnesswhere the signs or symptoms have recurred orcontinued in the absence of exposure in the workplace.This paragraph recognizes that there are occupationalillnesses that may be diagnosed at somestage of the disease and may then progress withoutregard to workplace events or exposures. Such diseases,in other words, will progress without furtherworkplace exposure to the toxic substance(s) thatcaused the disease. Examples of such chronic workrelateddiseases are silicosis, tuberculosis, andasbestosis. With these conditions, the ill worker willshow signs (such as a positive TB skin test, a positivechest roentgenogram, etc.) at every medical examination,and may experience symptomatic bouts asthe disease progresses.Paragraph 1904.6(b)(2) recognizes that manychronic occupational illnesses, however, such as occupationalasthma, RADs, and contact dermatitis, aretriggered by exposures in the workplace. Thedifference between these conditions and thoseaddressed in paragraph 1904.6(b)(1) is that in thesecases exposure triggers the recurrence of symptomsand signs, while in the chronic cases covered in theprevious paragraph, the symptoms and signs recureven in the absence of exposure in the workplace.This distinction is consistent with the position takenby <strong>OSHA</strong> interpretations issued under the formerrecordkeeping rule (see the Guidelines discussionbelow). The Agency has included provisions related tonew cases/continuations of old cases in the final ruleto clarify its position and ensure consistent reporting.Paragraph 1904.6(b)(3) addresses how to record acase for which the employer requests a physician orother licensed health care professional (HCP) to makea new case/continuation of an old case determination.Paragraph (b)(3) makes clear that employers areto follow the guidance provided by the HCP for<strong>OSHA</strong> recordkeeping purposes. In cases where twoor more HCPs make conflicting or differing recommendations,the employer is required to base his orher decision about recordation based on the mostauthoritative (best documented, best reasoned, ormost persuasive) evidence or recommendation.The final rule’s provisions on the recording of newcases are nearly identical to interpretations of newcase recordability under the former rule. <strong>OSHA</strong> hashistorically recognized that it is generally an easiermatter to differentiate between old and new casesthat involve injuries than those involving illnesses:40<strong>OSHA</strong> RECORDKEEPINGHANDBOOK
the Guidelines stated that “the aggravation of a previousinjury almost always results from some newincident involving the employee * * * [w]hen workrelated,these new incidents should be recorded asnew cases on the <strong>OSHA</strong> forms, assuming they meetthe criteria for recordability * * *” (Ex. 2, p. 31).However, the Guidelines also stated that “certain illnesses,such as silicosis, may have prolonged effectswhich recur over time. The recurrence of thesesymptoms should not be recorded as a new case onthe <strong>OSHA</strong> forms. * * * Some occupational illnesses,such as certain dermatitis or respiratory conditions,may recur as the result of new exposures to sensitizingagents, and should be recorded as new cases.” ……In the final rule, <strong>OSHA</strong> has decided against theproposed approach of determining case resolutionbased on a certain number of days during which theinjured or ill employee did not lose time, receivetreatment, have signs or symptoms, or be restrictedto light duty. <strong>OSHA</strong> agrees with those commenterswho argued that the proposed approach was too prescriptiveand did not allow for the variations that naturallyexist from one injury and illness case to thenext. Further, the record contains no convincing evidenceto support a set number of days as appropriate.<strong>OSHA</strong> thus agrees with those commenters whopointed out that adoption of a fixed time intervalwould result in the overrecording of some injury andillness cases and the underrecording of others, andthus would impair the quality of the records.Further, <strong>OSHA</strong> did not intend to create an “injuryfree” time zone during which an injury or illnesswould not be considered a new case, regardless ofcause, as . . . suggested. Instead, <strong>OSHA</strong> proposedthat a case be considered a new case if either conditionapplied: the case resulted from a new event orexposure or 45 days had elapsed without signs,symptoms, or medical treatment, restricted work, ordays away from work. There are clearly cases wherean event or exposure in the workplace would because for recording a new case. A new injury maymanifest the same signs and symptoms as the previousinjury but still be a new injury and not a continuationof the old case if, for example, an employeesustains a fall and fractures his or her wrist, and fourmonths later falls again and fractures the wrist in thesame place. This occurrence is not a continuation ofthe fracture but rather a new injury whose recordabilitymust be evaluated. The final rule’s approach torecurrence/new case determinations avoids this andother recording problems because it includes no daycount limit and relies on one of the basic principlesof the recordkeeping system, i.e., that injuries or illnessesarising from events or exposures in the workplacemust be evaluated for recordability.In response to those commenters who raisedissues about inconsistency between the <strong>OSHA</strong> systemand workers’ compensation, <strong>OSHA</strong> notes thatthere is no reason for the two systems, which servedifferent purposes (recording injuries and illnessesfor national statistical purposes and indemnifyingworkers for job-related injuries and illnesses) to usethe same definitions. Accordingly, the final rule doesnot rely on workers’ compensation determinations toidentify injuries or illness cases that are to be considerednew cases for recordkeeping purposes….…<strong>OSHA</strong> has not included any provisions in thefinal rule that require an employer to rely on a physicianor other licensed health care professional or thattell a physician or other licensed health care professionalhow to treat an injured or ill worker, or whento begin or end such treatment. In the final rule<strong>OSHA</strong> does require the employer to follow any determinationa physician or other licensed health careprofessional has made about the status of a newcase. That is, if such a professional has determinedthat a case is a new case, the employer must recordit as such. If the professional determines that thecase is a recurrence, rather than a new case, theemployer is not to record it a second time. In addition,the rule does not require the employee, or theemployer, to obtain permission from the physician orother licensed health care professional before theemployee can return to work. <strong>OSHA</strong> believes that theemployer is capable of, and often in the best positionto, make return-to-work decisions….…”A recurrence of a previous work-related injuryor illness should only be considered a new case whenthe injury or illness has completely healed. Severemuscle and nerve damage can take many weeks ormonths to properly heal.” The final rule takes suchdifferences into account, as follows. If the previousinjury or illness has not healed (signs and symptomshave not resolved), then the case cannot be consideredresolved. The employer may make this determinationor may rely on the recommendation of a physicianor other licensed health care professional whendoing so. Clearly, if the injured or ill employee is stillexhibiting signs or symptoms of the previous injuryor illness, the malady has not healed, and a new casedoes not have to be recorded. Similarly, if work activitiesaggravate a previously recorded case, there is noneed to consider recording it again (although theremay be a need to update the case information if theaggravation causes a more severe outcome than theoriginal case, such as days away from work)….§1904.6<strong>OSHA</strong> RECORDKEEPINGHANDBOOK41
