Medical surveillance is the part of Cal/OSHA compliance that employers most often assume someone else is handling. A manufacturer, a painting contractor, a dental practice, and a cabinet shop can each be subject to two or three Title 8 standards that require exams, blood tests, questionnaires, or screening on a fixed schedule. When a compliance officer asks for the records and gets a stack of pre-employment physicals, the citation usually follows. This article was written with clinical input from Zennin Sedacey-McNeil, LVN (VN 741259), McNeil Safety Consulting’s staff nurse, whose certifications in IV Therapy/Blood Withdrawal (IV), Infection Preventionist (IP), Treatment Nurse (TX), and Director of Staff Development (DSD) inform the clinical guidance below.
What Medical Surveillance Is and Who Provides It
Medical surveillance is a set of scheduled medical evaluations tied to a specific exposure, required by a specific standard, and provided at no cost to the employee at a reasonable time and place. Most Title 8 substance standards require it to be performed by or under the supervision of a physician or other licensed health care professional, abbreviated PLHCP, defined as someone whose legally permitted scope of practice allows them to independently provide, or be delegated the responsibility to provide, the required services. That is why a licensed nurse under physician supervision can lawfully administer questionnaires, draw blood, run screenings, and coordinate a program. A pre-employment physical or DOT exam does not satisfy a Title 8 requirement unless the content, timing, and written opinion match what the standard specifies.
Six Standards That Require It
Respirators: Section 5144(e)
Title 8, Section 5144 requires a medical evaluation before an employee is fit tested or required to use a respirator. The evaluation uses the questionnaire in Appendix C, or an examination that obtains the same information, administered confidentially during normal working hours or at a time and place convenient to the employee. A follow-up examination is required for any employee who answers yes to questions 1 through 8 in Section 2, Part A of Appendix C. The employer has to give the PLHCP the type and weight of the respirator, duration and frequency of use, expected physical effort, other protective equipment worn, and temperature and humidity extremes. The written recommendation states only whether the employee is medically able to use the respirator, any limitations, whether follow-up is needed, and that the employee received a copy. Re-evaluation is required when the employee reports symptoms, when the PLHCP, a supervisor, or the program administrator calls for it, or when workplace conditions change substantially. This is the most common medical surveillance requirement in California, and the most commonly missed.
Lead in Construction: Section 1532.1
Section 1532.1 was substantially amended, and the current numbers are far lower than many contractors remember. The action level is now 2 micrograms per cubic meter as an 8-hour time-weighted average, and the permissible exposure limit is 10. Medical surveillance is required for employees exposed at or above the action level, except those not exposed at that level for 30 or more days in any 12 consecutive months. Initial blood lead testing must be done prior to assignment to work where exposure is reasonably expected at or above the action level, then at least every 2 months for the first 6 months, then every 6 months, and at least monthly for any employee whose last blood lead level was at or above 20 micrograms per deciliter. Medical removal is now triggered when the last two blood lead results are at or above 20 micrograms per deciliter, or the 6-month average is at or above 20, and the employee cannot return until two consecutive tests at least 30 days apart are both below 15. The employer must notify each employee of the result in writing within five working days. Blood draws for this program are routine for a nurse with an IV and blood withdrawal certification.
Respirable Crystalline Silica in Construction: Section 1532.3
Section 1532.3 requires medical surveillance for each employee who will be required to use a respirator under the standard for 30 or more days per year. The initial examination must be made available within 30 days after initial assignment unless the employee had a qualifying exam within the last three years. It consists of a medical and work history focused on silica exposure, a physical examination with emphasis on the respiratory system, a chest X-ray interpreted by a NIOSH-certified B Reader, a pulmonary function test measuring FVC and FEV1, testing for latent tuberculosis infection, and any other tests the PLHCP considers appropriate. Periodic examinations are required at least every three years. If the chest X-ray is classified as 1/0 or higher, a specialist examination must be made available within 30 days. The written opinion to the employer is limited to the date, confirmation that the exam met the requirements, and any recommended limitations on respirator use.
Formaldehyde: Section 5217
Section 5217 sets a PEL of 0.75 parts per million as an 8-hour TWA, a short-term exposure limit of 2 ppm over 15 minutes, and an action level of 0.5 ppm. Medical surveillance is required for employees exposed at or above the action level or above the STEL, for employees who develop signs and symptoms of overexposure, and for employees exposed during emergencies. The core is a medical disease questionnaire before assignment and annually thereafter. A physical examination is required when the physician determines the employee is at increased risk, and emergency exposures require an examination as soon as possible. This standard reaches embalmers, pathology labs, some composite wood operations, and salons using certain hair-smoothing products.
Aerosol Transmissible Diseases: Section 5199
Section 5199 applies to hospitals, clinics, skilled nursing facilities, correctional health, home health, laboratories, and other settings with occupational exposure to airborne infectious disease. The employer must make assessment for latent tuberculosis infection available to all employees with occupational exposure, at least annually and more often if public health guidelines or the local health officer recommend it. Employees with a baseline positive TB test receive an annual symptom screen instead, and a TB conversion requires referral to a knowledgeable PLHCP. The employer must also make available the vaccine doses listed in Appendix E and the seasonal influenza vaccine, and provide post-exposure medical evaluation after a significant exposure. Medical records must be kept for the duration of employment plus 30 years.
Noise: Section 5097
Section 5097 requires an audiometric testing program whenever employee noise exposures equal or exceed an 8-hour time-weighted average of 85 decibels. A baseline audiogram must be obtained within 6 months of first exposure at that level, or within one year if a mobile test van is used, preceded by at least 14 hours without workplace noise, with annual audiograms after that. Tests must be performed by an audiologist, otolaryngologist, or other physician, or by a technician certified by the Council for Accreditation in Occupational Hearing Conservation. A standard threshold shift is an average change of 10 dB or more at 2000, 3000, and 4000 Hz in either ear, and the employee must be informed in writing within 21 days of that determination.
How to Run a Program That Holds Up
These standards share the same failure modes: no one determined which employees are covered, the timing slipped, the provider did not know what standard they were examining for, and the written opinions went into the personnel file. A program that holds up has four parts.
- An exposure determination. Air sampling for lead, silica, and formaldehyde and noise dosimetry are what tell you who is at or above an action level. Without them you are guessing.
- A roster with dates. Each covered employee, each applicable standard, the last evaluation, and the next due date.
- A briefed provider. Send the PLHCP the section number, the exposure data, and the information each standard requires. A generic clinic will otherwise produce a generic physical.
- Two sets of records. The written opinions the employer is entitled to see go in one file; the underlying medical information stays in a separate confidential medical record subject to Section 3204.
What to Do This Week
- List every task and material in your operation and mark which of the six standards could apply.
- Confirm you have current exposure data for lead, silica, formaldehyde, and noise; if not, schedule sampling.
- Verify every mandatory respirator user has an Appendix C evaluation and a PLHCP clearance dated before their fit test.
- For lead work, check that blood lead results are on schedule and written notices went out within five working days.
- For silica respirator users, confirm the initial exam happened within 30 days of assignment and the three-year periodic is calendared.
- In healthcare settings, confirm annual TB assessment dates and Appendix E vaccine offers are documented.
- Separate medical records from personnel files if they are together.
