Silica Physicals
A Silica Physical Exam is required by OSHA to be performed upon hire (or prior to silica exposure) and every 3 years thereafter (or more frequently if determined by a physician).
Workers who inhale these very small crystalline silica particles are at increased risk of developing serious silica-related diseases, including:
- Silicosis, an incurable lung disease that can lead to disability and death;
- Lung cancer;
- Chronic obstructive pulmonary disease (COPD); and
- Kidney disease.
Why Silica Physicals?
Respirable crystalline silica are very small particles at least 100 times smaller than ordinary sand and are are created when cutting, sawing, grinding, drilling, and crushing stone, rock, concrete, brick, block, and mortar.
Industrial sand used in certain operations, such as foundry work and hydraulic fracturing (fracking), is also a source of respirable crystalline silica exposure. About 2.3 million people in the U.S. are exposed to silica at work.

Protecting your employees from exposure to this harmful agent is crucial to the success of your business.
What are the Risks?

- Kidney disease

What are the OSHA Regulations?
OSHA 29 CFR 1910.1153-“Respirable Crystalline Silica”
- OSHA's Respirable Crystalline Silica standard for general industry and maritime requires employers to limit worker exposures to respirable crystalline silica and to take other steps to protect workers. The standard requires employers to:
- Assess employee exposures to silica if it may be at or above an action level of 25 µg/m3 (micrograms of silica per cubic meter of air), averaged over an 8-hour day;
- Protect workers from respirable crystalline silica exposures above the permissible exposure limit (PEL) of 50 µg/m3, averaged over an 8-hour day;
- Limit workers’ access to areas where they could be exposed above the PEL;
- Use dust controls to protect workers from silica exposures above the PEL;
- Provide respirators to workers when dust controls cannot limit exposures to the PEL;
- Use housekeeping methods that do not create airborne dust, if feasible;
- Establish and implement a written exposure control plan that identifies tasks that involve exposure and methods used to protect workers;
- Offer medical exams – including chest X-rays and lung function tests – every three years for workers exposed at or above the action level for 30 or more days per year;
- General industry and maritime employers must comply with all requirements of the standard by June 23, 2018, except for the following:
- Medical surveillance must be offered to employees who will be exposed at or above the action level for 30 or more days a year starting on June 23, 2020. (Medical surveillance must be offered to employees who will be exposed above the PEL for 30 or more days a year starting on June 23, 2018.)
- Hydraulic fracturing operations in the oil and gas industry must implement engineering controls to limit exposures to the new PEL by June 23, 2021.
- Construction employers must comply with all requirements of the standard by September 23, 2017, except requirements for laboratory evaluation of exposure samples, which begin on June 23, 2018.
What do we do?
Our methods for physicals follow OSHA's Standard Guidelines
The respirable crystalline silica standard requires at a minimum the following:
- Physical exam with special emphasis on the respiratory system
- TB testing
- Chest X-Ray with B Reader
- Pulmonary Function Test
In addition, the silica physical may also include:
The physician will also review the employer’s notes that detail the patient’s job description and level of exposure to silica and other hazardous materials.
Hearing Test
Vision Test
EKG
Urine and Blood Samples
Note: Above tests are at the physician’s discretion based on medical history and current/past exposures
How do we perform this service?
On-Site
CNS OccMed will complete all testing at the employer’s worksite and have training and counseling options available to meet your needs (all services provided in a variety of languages)
Quick EvaluAtions
The employees will receive immediate evaluations and a written medical option by the physician as required by OSHA
Professional Assessments
All testing will be performed by trained technicians, nurses, Physician’s and Advanced Practice Providers (NPs and PAs)
MOBILE FRIENDLY
The mobile medical unit is deployed for this service at a worksite.
Employees will be comfortably interviewed, screened and tested in the exam rooms within the mobile unit by a PLHCP, trained nurses, medical assistants, spirometry and hearing conservation technicians.
All testing that may be required is available within the mobile unit.
Employees and employers will receive a medical clearance determination or written medical opinion at the time of their physical.
Employees will be back to work within 1-1 ½ hours.

Develop a Medical Strategy
Our Occupational Medicine Team will develop a custom plan for your company. You may need a combination of services like physicals, COVID-19 testing, and drug testing, and you may also need these services performed on-site.
