OSHA Injury and Illness Recordkeeping for Stone Shops

Recordkeeping is the part of shop safety that nobody enjoys and almost everybody gets partly wrong. It has no visible payoff on a normal Tuesday, it lives in a binder or a spreadsheet that gets opened twice a year, and the rules governing it are written in a question-and-answer style that reads clearly until you try to apply it to an actual injury. Then the questions start. Does a cut that got glued shut count? What about a fabricator who came back the next morning but could not lift? Does the day of the injury count as a day away? The answers are all in 29 CFR Part 1904, and they are more specific than most shop owners expect.

Getting this right matters for reasons beyond avoiding a citation. The log is the only place where a shop's injury history is written down in a consistent format, which makes it the only honest input to any decision about guarding, staffing, handling equipment, or training budget. A shop that records accurately can see that most of its lost time comes from slab handling rather than from saws, and can act on that. A shop that under-records sees nothing and keeps buying the wrong solutions. This article walks the rules as they apply to a fabrication business: who is covered, what makes a case recordable, which forms exist, what the deadlines are, and how the resulting data gets used.

Who Is Covered and What Makes a Case Recordable

Two partial exemptions exist. Under 29 CFR 1904.1, a company that had ten or fewer employees at all times during the previous calendar year does not have to keep the records unless OSHA or the Bureau of Labor Statistics asks in writing. Under 1904.2, establishments in the low-hazard industries listed in the non-mandatory appendix to subpart B are also excused. That appendix is made up of retail, financial, professional, and personal service classifications. Stone fabrication sits in manufacturing, and installation work sits in construction, so neither industry exemption applies. If you have more than ten employees, you keep records.

Both exemptions are partial rather than total, and the distinction trips people up. Every employer covered by the Act, including the smallest shop and the most exempt industry, still has to report work-related fatalities, in-patient hospitalizations, amputations, and losses of an eye directly to OSHA under 1904.39. The exemption removes the logging duty, not the reporting duty. A four-person shop with no 300 Log at all is still obliged to pick up the phone when somebody loses a fingertip to a saw.

A case is recordable when it is work-related, is a new case, and meets one of the general criteria in 1904.7: death, days away from work, restricted work or transfer to another job, medical treatment beyond first aid, or loss of consciousness. There is also a catch-all for a significant injury or illness diagnosed by a physician or other licensed health care professional, which is how conditions like a fractured bone or a punctured eardrum land on the log even without days away. Work-relatedness is presumed when an event or exposure in the work environment caused or contributed to the condition, subject to a specific list of exceptions.

Medical treatment beyond first aid is the criterion that generates the most argument, and the rule settles it with a closed list. Anything on the first aid list in 1904.7(b)(5)(ii) is first aid no matter who administers it, and anything not on the list is medical treatment. The distinction that catches fabrication shops most often is wound coverings versus wound closures. Bandages, gauze pads, butterfly bandages, and Steri-Strips are first aid. Sutures, staples, and wound-closing glue are medical treatment, which makes the case recordable even if the worker finishes the shift and comes back the next morning.

Forms, Deadlines, and the Mechanics of the Log

Three Forms, Three Jobs

The system runs on three documents. The OSHA 300 Log is the running list of recordable cases for the year, one line per case, with columns for days away, job transfer or restriction, and case classification. The OSHA 301 Incident Report is the detail sheet behind each line, capturing what the employee was doing, what happened, what the injury was, and what object or substance harmed them. The OSHA 300A Annual Summary is the year-end tally that gets certified and posted. Equivalent forms are allowed provided they capture the same information and are as readable and understandable as the originals.

Dates That Actually Bind

Four dates matter. A recordable case must be entered on the 300 Log and its 301 Report within seven calendar days of receiving information that it occurred, under 1904.29(b)(3). The 300A must be posted no later than February 1 of the following year and left in place until April 30, under 1904.32. Establishments required to submit electronically must do so by March 2 for the prior calendar year, under 1904.41. And under 1904.33 the 300 Log, the privacy case list, the annual summary, and the 301 Reports are kept for five years following the end of the calendar year they cover.

Two details on the annual summary catch shops out. The 300A has to be completed, certified, and posted even in a year with zero recordable cases, with zeros written in the totals. And the certification is not a clerical signature: the rule requires a company executive to certify that the summary is correct and complete, and it limits that role to a company owner, a corporate officer, the highest-ranking company official working at the establishment, or that person's immediate supervisor. A shop foreman signing on behalf of an absent owner does not satisfy it.

Counting Days and Handling Privacy

Day counting has its own logic. Days away and days of restricted work or transfer are counted in calendar days, not scheduled work days, so weekends and shutdowns count if the worker was still restricted. The day of the injury itself is not counted; counting begins the following day. If a case runs past 180 calendar days of days away, job transfer, or restriction, you may cap the count at 180 and stop tracking. Restricted work means the worker cannot perform all the routine functions of the job or cannot work the full shift they would otherwise have worked.

The three forms plus the privacy list make up the file an inspector will ask to see.

Privacy cases are a small but strict corner of the rule. For a defined set of cases you must not enter the employee's name on the 300 Log, writing privacy case in the name field instead. The categories in 1904.29(b)(7) include an injury or illness to an intimate body part or the reproductive system, an injury or illness resulting from a sexual assault, needlestick injuries and cuts from sharp objects contaminated with another person's blood or other potentially infectious material,, mental illnesses, cases of HIV infection, hepatitis or tuberculosis, and other illnesses where the employee voluntarily asks that their name be left off. The rule that you may not enter the name at all sits just above it at 1904.29(b)(6). You keep a separate confidential list matching those case numbers to names.

The obligation does not stop when the year ends. Under 1904.33 the stored logs must be updated during the five-year retention period to add newly discovered recordable cases and to reflect changes in the classification of cases already recorded. A back injury logged as restricted work in December that turns into surgery and eight weeks away in February requires the earlier log to be corrected. The annual summary and the 301 forms do not have to be updated, but the log does, and that is a common gap in shops that treat the binder as closed once the 300A is posted.

Employees have rights in this system that are easy to overlook. Under 1904.35 you must set up a way for employees to report work-related injuries and illnesses promptly, inform them how to do it, and make clear that they will not be retaliated against for reporting. On request, an employee, former employee, personal representative, or authorized employee representative is entitled to a copy of the relevant 300 Log by the end of the next business day. Incentive schemes that quietly punish reporting sit badly with this section.

Severe Injuries, Silica Cases, and Electronic Submission

Reporting under 1904.39 runs on a separate and much faster clock than recording. A work-related fatality must be reported to OSHA within eight hours of learning of it. A work-related in-patient hospitalization, amputation, or loss of an eye must be reported within twenty-four hours. The rule sets outer limits on the triggering event as well: a fatality is reportable if it occurs within thirty days of the work-related incident, and a hospitalization, amputation, or eye loss is reportable if it occurs within twenty-four hours of the incident.

Amputation is a live category in stone fabrication, and it is defined more broadly than most people assume. It covers traumatic loss of a limb or other external body part, including partial or complete loss of bone, with or without a reattachment attempt. A fingertip taken off by a saw, a router, or a slab that shifted on a rack falls inside it. In-patient hospitalization means a formal admission for care or treatment, so an emergency department visit that ends in discharge the same day is a different matter from an admission.

Illnesses are recordable on the same log as injuries, and this is where a fabrication shop's biggest long-term exposure shows up. A physician's diagnosis of a work-related respiratory condition arising from silica exposure is recorded like any other work-related illness, in the appropriate illness column. Because advanced silicosis is progressive and does not resolve, OSHA guidance treats such a case as one that is never closed under the recordkeeping system, which has implications for how long the case continues to affect your day counts and classifications.

Hearing loss has its own recording rule at 1904.10, which is worth knowing in a shop full of saws, grinders, and compressors. A case is recordable when an audiogram shows a work-related standard threshold shift and the employee's total hearing level is 25 decibels or more above audiometric zero, averaged at 2000, 3000, and 4000 hertz, in the same ear as the shift. A shift alone is not enough; the 25 decibel level has to be there too. Shops running a hearing conservation program should make sure the audiologist's report reaches the recordkeeper.

Electronic submission is layered by size and industry under 1904.41. Establishments with 20 to 249 employees in the industries listed in appendix A to subpart E, which includes all of manufacturing and all of construction, submit the 300A data annually. Establishments with 250 or more employees that are required to keep records also submit the 300A. Establishments with 100 or more employees in the higher-hazard industries listed in appendix B submit the detailed 300 and 301 information as well. Submissions go through the Injury Tracking Application on the OSHA website, by web form, CSV upload, or interface.

State plan states add a wrinkle. States operating their own OSHA-approved programs must have recordkeeping requirements at least as effective as the federal rule, and several impose additional reporting duties or shorter timelines. If you operate shops in more than one state, check each state's rules rather than assuming the federal baseline covers you, and keep the state reporting phone number posted alongside the federal one.

Turning the Log Into Something Useful

The log becomes a management tool the moment you calculate rates from it. The standard formula multiplies the number of cases by 200,000 and divides by the total hours worked by all employees, where 200,000 represents the hours worked by roughly one hundred full-time employees in a year. Run it for total recordable cases and separately for cases involving days away, restriction, or transfer. Hours worked should exclude vacation, sick leave, and holidays. Once you have the numbers you can compare year to year and against published industry figures.

Rates are a starting point rather than an answer, particularly in a small shop where a single bad month swings the figure wildly. What repays more attention is the pattern in the 301 reports: which task, which station, which shift, which crew, which time of day. A stone shop that reads a year of incident reports carefully usually finds that a handful of activities generate most of the cases, and that those activities are the ones nobody has re-examined since the shop moved into the building.

Pair the log with a near-miss record that has no regulatory weight at all. Recordable cases are a lagging indicator by definition, and in a shop with a good year there may be too few of them to see anything. Near misses are far more numerous: the slab that started to go over, the blade guard found swung back, the forklift that clipped a rack. Log them in a simple format, review them monthly, and treat them as free information about where the next recordable case is going to come from.

Keep the recordkeeping file inspection-ready rather than assembling it under pressure. That means the current 300 Log, the 301 Reports, the certified 300A summaries and their supporting logs for the retention period, the privacy case list, and evidence that the 300A was actually posted for the required window. Store them somewhere that survives a change of office manager. Paper in a filing cabinet is acceptable; a spreadsheet on one person's laptop with no backup is a problem waiting to surface.

Finally, treat accuracy as the point rather than a low count as the goal. Under-recording buys a better-looking number and costs the shop the ability to see its own risks, and it collapses badly during an inspection because the treatment records and workers compensation claims tell a different story than the log. Shops that record honestly, review the data, and spend money against what it shows tend to end up with genuinely lower numbers a few years later, which is the only version worth having.

Much of what shows up on a fabrication shop's log traces back to handling and tooling decisions made long before the injury. Reviewing the material handling, guarding, and dust control products in the full catalog alongside a year of your own incident reports is a more productive exercise than reading either one on its own.
