The Log or Work-Related Injuries and Illnesses (Form 300) is
used to classify work- related injuries and illnesses and to note the extent and
severity of each case. When an incident occurs, use the to record specific
details about what happened and how it happened.
The Summary —a separate form ( Form 300A) —shows the
totals for the year in each category. At the end of the year, post the in a
visible location so that your employees are aware of the injuries and illnesses
occurring in their workplace.
Employers must keep a for each establishment or site. If you
have more than one establishment, you must keep a separate and for each physical
location that is expected to be in operation for one year or longer.
Note that your employees have the right to review your injury
and illness records. For more information, see 29 Code of Federal Regulations
Cases listed on the are not necessarily eligible for workers
’compensation or other insurance benefits. Listing a case on the does not mean
that the employer or worker was at fault or that an OSHA standard was violated.
When is an injury or illness considered work- related?
An injury or illness is considered work- related if an event or exposure in the
work environment caused or contributed to the condition or significantly
aggravated a preexisting condition. Work- relatedness is presumed for injuries
and illnesses resulting from events or exposures occurring in the workplace,
unless an exception specifically applies. See 29 CFR Part 1904.5( b) ( 2) for
the exceptions. The work environment includes the establishment and other
locations where one or more employees are working or are present as a
condition of their employment. See 29 CFR Part 1904.5( b) ( 1) .
Which work-related injuries and illnesses should you record?
Record those work- related injuries and illnesses that result in:
- loss of consciousness,
- days away from work,
- restricted work activity or job transfer, or
- medical treatment beyond first aid.
You must also record work- related injuries and illnesses that
are significant (as defined below) or meet any of the additional criteria listed
You must record any significant work-related injury or illness
that is diagnosed by a physician or other licensed health care professional. You
must record any work- related case involving cancer, chronic irreversible
disease, a fractured or cracked bone, or a punctured eardrum. See 29 CFR 1904.7.
What are the Additional Criteria?
You must record the following conditions when they are work- related:
- any needlestick injury or cut from a sharp object that is
contaminated with another person ’s blood or other potentially infectious
- any case requiring an employee to be medically removed
under the requirements of an OSHA health standard;
- tuberculosis infection as evidenced by a positive skin test
or diagnosis by a physician or other licensed health care professional after
exposure to a known case of active tuberculosis.
What is Medical Treatment?
Medical treatment includes managing and caring for a
patient for the purpose of combating disease or disorder. The following are not
considered medical treatments and are NOT recordable:
- visits to a doctor or health care professional solely for
observation or counseling;
- diagnostic procedures, including administering prescription
medications that are used solely for diagnostic purposes; and
- any procedure that can be labeled first aid.
(See below for more information about first aid.)
What do you need to do?
1. Within 7 calendar days after you receive information about
a case, decide if the case is recordable under the OSHA recordkeeping
2. Determine whether the incident is a new case or a
recurrence of an existing one.
3. Establish whether the case was work-related.
4. If the case is recordable, decide which form you will fill
out as the injury and illness incident report.
You may use OSHA's 301: Injury and Illness Incident Report or
an equivalent form. Some state workers compensation, insurance or other
reports may be acceptable substitutes, as long as they provide the same
information as the OSHA 301.
How to work with the log
1. Identify the employee involved unless it is a privacy
concern case as described below.
2. Identify when and where the case occurred.
3. Describe the case, as specifically as you can.
4. Classify the seriousness of the case by recording the
most serious outcome associated with the case, with column J (other serious
recordable cases) being the least serious and column G (Death) being the most
5. Identify whether the case is an injury or illness. If
the case is an injury, check the injury category. If the case is an illness,
check the appropriate illness category.
What is First Aid
If the incident required only the following types of treatment, consider it
first aid. Do NOT record the case if it involves only:
- using non- prescription medications at non-prescription
- administering tetanus immunizations;
- cleaning, flushing, or soaking wounds on the skin surface;
- using wound coverings, such as bandages, BandAids ™, gauze
pads, etc. , or using SteriStrips ™or butterfly bandages.
- using hot or cold therapy;
- using any totally non- rigid means of support, such as
elastic bandages, wraps, non- rigid back belts, etc. ;
- using temporary immobilization devices while transporting
an accident victim ( splints, slings, neck collars, or back boards) .
- drilling a fingernail or toenail to relieve pressure, or
draining fluids from blisters;
- using eye patches;
- using simple irrigation or a cotton swab to remove foreign
bodies not embedded in or adhered to the eye;
- using irrigation, tweezers, cotton swab or other simple
means to remove splinters or foreign material from areas other than the eye;
- using finger guards;
- using massages;
- drinking fluids to relieve heat stress
How do you decide if the case involved restricted work?
Restricted work activity occurs when, as the result of a work- related injury or
illness, an employer or health care professional keeps, or recommends keeping,
an employee from doing the routine functions of his or her job or from working
the full workday that the employee would have been scheduled to work before the
injury or illness occurred.
How do you count the number of days of restricted work activity or the
number of days away from work?
Count the number of calendar days the employee was on restricted work activity
or was away from work as a result of the recordable injury or illness. Do not
count the day on which the injury or illness occurred in this number.
Begin counting days from the day after the incident occurs. If
a single injury or illness involved both days away from work and days of
restricted work activity, enter the total number of days for each. You may stop
counting days of restricted work activity or days away from work once the total
of either or the combination of both reaches 180 days.
Under what circumstances should you NOT enter the employee ’s name on the
OSHA Form 300?
You must consider the following types of injuries or illnesses to be privacy
- an injury or illness to an intimate body part or to the
- an injury or illness resulting from a sexual assault,
- a mental illness,
- a case of HIV infection, hepatitis, or tuberculosis,
- a needlestick injury or cut from a sharp object that is
contaminated with blood or other potentially infectious material ( see 29 CFR
Part 1904.8 for definition) , and
- other illnesses, if the employee independently and
voluntarily requests that his or her name not be entered on the log.
You must not enter the employee ’s name on the OSHA 300 Log
for these cases. Instead, enter "privacy case "in the space normally used for
the employee ’s name. You must keep a separate, confidential list of the case
numbers and employee names for the establishment ’s privacy concern cases so
that you can update the cases and provide information to the government if asked
to do so.
If you have a reasonable basis to believe that information
describing the privacy concern case may be personally identifiable even though
the employee ’s name has been omitted, you may use discretion in describing the
injury or illness on both the OSHA 300 and 301 forms. You must enter enough
information to identify the cause of the incident and the general severity of
the injury or illness, but you do not need to include details of an intimate or
What if the outcome changes after you record the case?
If the outcome or extent of an injury or illness changes after
you have recorded the case, simply draw a line through the original entry or, if
you wish, delete or white- out the original entry. Then write the new entry
where it belongs. Remember, you need to record the most serious outcome for each

radium) ; effects of nonionizing radiation ( welding flash, ultra- violet
rays, lasers) ; anthrax; bloodborne pathogenic diseases, such as AIDS, HIV,
hepatitis B or hepatitis C; brucellosis; malignant or benign tumors;
When must you post the Summary?
You must post the Summary only —not the Log —by February 1 of
the year following the year covered by the form and keep it posted until April
30 of that year. How long must you keep the Log and Summary on file?
You must keep the Log and Summary for 5 years following the
year to which they pertain.
Do you have to send these forms to OSHA at the end of the year?
No. You do not have to send the completed forms to OSHA unless
specifically asked to do so.
Establish whether the case was work-related
If the case is recordable, decide which form you will fill out as the injury and
illness incident report. You may use or an equivalent form. Some state workers
compensation, insurance, or other reports may be acceptable substitutes, as long
as they provide the same information as the OSHA 301.
Classify the seriousness of the case by recording the
associated with the case, with column J ( Other recordable cases) being the
least serious and column G ( Death) being the most serious.
The Occupational Safety and Health ( OSH) Act of 1970 requires
certain employers to prepare and maintain records of work- related injuries and
illnesses. Use these definitions when you classify cases on the Log. OSHA’s
recordkeeping regulation ( see 29 CFR Part 1904) provides more information about
the definitions below.
Calculating Injury and Illness Incidence
What is an incidence rate?
An incidence rate is the number of recordable injuries and illnesses
occurring among a given number of full- time workers ( usually 100 full-time
workers) over a given period of time ( usually one year) . To evaluate your firm
’s injury and illness experience over time or to compare your firm ’s experience
with that of your industry as a whole, you need to compute your incidence rate.
Because a specific number of workers and a specific period of time are involved,
these rates can help you identify problems in your workplace and/ or progress
you may have made in preventing work-related injuries and illnesses.
How do you calculate an incidence rate?
You can compute an occupational injury and illness incidence rate for all
recordable cases or for cases that involved days away from work for your firm
quickly and easily. The formula requires that you follow instructions in
paragraph ( a) below for the total recordable cases or those in paragraph ( b)
for cases that involved days away from work, and for both rates the instructions
in paragraph ( c) .
( a) To find out the total number of recordable injuries and illnesses that
occurred during the year, count the number of line entries on your OSHA Form
300, or refer to the OSHA Form 300A and sum the entries for columns ( G) , ( H)
,( I) , and ( J) .
( b) To find out the number of injuries and illnesses that involved days away
from work, count the number of line entries on your OSHA Form 300 that received
a check mark in column ( H) , or refer to the entry for column ( H) on the OSHA
( c) The number of hours all employees actually worked during the year .
Refer to OSHA Form 300A and optional worksheet to calculate this number.
You can compute the incidence rate for all recordable cases of injuries and
illnesses using the following formula:
Total number of injuries and illnesses ÷Number of hours worked by all
employees X 200,000 hours = Total recordable case rate (The 200,000 figure in
the formula represents the number of hours 100 employees working 40 hours per
week, 50 weeks per year would work, and provides the standard base for
calculating incidence rates. )
You can compute the incidence rate for recordable cases involving days away
from work, days of restricted work activity or job transfer ( DART) using the
( Number of entries in column H + Number of entries in column I) ÷Number of
hours worked by all employees
