Workplace Health Examination
What is a health examination?
- Divided into general and special health examinations
- Night work and pre-placement exams are often missed
- Results kept separate as sensitive data
In practice, carrying out health examinations means producing a definitive list of 'who in our company is exposed to what, and how much.' To pick the eligible employees, you need to bring work environment monitoring results, MSDS, process-by-process placement data, and attendance records into one table, and in doing so exposure that previously existed only on paper comes to light. That is why an examination is not a wellness event but the starting point of exposure management, and the moment you build the list, the people you must manage are fixed.
Intervals and types are clearly distinct, too. For general health examinations, the standard is once every 2 years for office workers and once a year for other workers. Special health examinations have separate intervals of 6, 12, or 24 months depending on the hazardous factor. The timing of the first exam after placement also varies by factor. For example, for night work, the first exam is due within 6 months of placement, followed by a 12-month cycle. Night-work eligibility means working between midnight and 5 a.m. an average of 4 or more times a month over 6 months, or an average of 60 or more hours a month in that window.
There is more than one type of examination, not just the regular one. There is a pre-placement examination before assignment to hazardous work, an ad hoc examination when symptoms such as occupational asthma or dermatitis appear, and a temporary examination ordered by the head of the competent labor office. Results are reported as health management categories such as A, C1, C2, D1, D2, and R. When a D1 result (suspected occupational disease) comes back, real measures such as a job change or reduced working hours must follow, and a record of that follow-through must be kept.
The most common misconception on the shop floor is the excuse, "We couldn't do it because employees refused." The duty to conduct checkups lies with the employer, so accountability follows for every employee who goes unscreened, and collecting the results and filing them in a cabinet is separately cited as a failure to take follow-up measures. Conversely, if you keep results on an HR shared drive or use them in promotion or contract-renewal decisions, you invite misuse of sensitive information and discrimination disputes at the same time. Skipping pre-placement checkups is even worse. Years later, when hearing loss or a respiratory illness becomes an issue, the company has no baseline data from the hiring date and cannot show the work-relatedness question was properly handled.

Company A, a second-tier supplier of auto parts with 210 employees, runs its painting and welding lines on a three-crew, two-shift schedule. In an inspection by the regional labor office last year, it was cited because its night-shift workers had been left off the special health examination list altogether, and about half of the pre-placement examination records for the past three years were missing. (Hypothetical example)
- The head of safety and health got six months of raw attendance data from HR and counted, by hand, everyone who worked between midnight and 5 a.m. at least four times a month on average. The result was 112 people, not the 88 in the report. Another 24 subcontracted inspectors were missing from the list.
- The occupational health manager overlaid work-environment measurement results and MSDS data on the process map, tagging solvent, welding fume, and noise exposure on the paint line by job role. When the team lead said, "Let's organize this by person, not by line," they built a new exposure history sheet for each individual.
- The HR manager reversed the approval order for assignments so that painting and welding assignments cannot be confirmed in the system until the pre-placement health examination results are in. In the first month, three assignments slipped by a week each, but the omissions stopped.
- The examinations produced 2 D1 and 9 C1 results. Those rated D1 were moved to non-exposure processes within 4 weeks, and a re-examination was scheduled in 6 months for those rated C1. The process no longer ended with receiving the results and filing them away, as it used to.
- The result files were moved to a folder only the occupational health manager can access and deleted from the HR team’s shared drive. Even when a team leader asks, the reply is limited to whether the person is fit or conditionally fit for the job in question, never the diagnosis.
- At the follow-up review a year later, the special health examination completion rate was 100% for all 112 eligible employees, with zero findings on missed exams or follow-up measures. The two night-shift employees with abnormal findings who were moved to day shifts were reclassified to C2 on re-examination.
