In re: Your letter of October 7, 1976, 1926.50(c) Medical Services and First Aid
Dear Ms. Moser:

Your letter requests an interpretation of the subject standard as it pertains to the accessibility of a hospital or physician in terms of distance and travel time. As a general rule, we recommend that a person trained in first aid be available on the site whenever professional medical attention is more than eight minutes away from any point on the site. However, the conditions present on any particular job site may make this eight-minutes guide line inadequate.

If employees are working with materials that could adversely affect their respiration, or are subject to electrical shock that could cause loss of the breathing function, the eight-minutes time period is too long. Irreversible brain damage can result in four minutes due to the lack of oxygen. Accordingly, of hazards of such mature are present (except in isolated instances) and professional medical attention is not available within four minutes of the onset of the condition, then the employer should comply with the requirement for a person trained in first aid to be available at the worksite.

When the hazards on a worksite are of a less critical nature, the travel time factor becomes less critical also. But we recommend that the eight-minutes travel time be considered as the maximum.

An employer must decide what action to take to achieve compliance with the cited standard. We would add that the changing conditions on a construction site make it necessary for the employer to review his actions periodically to assure that his safety and health measures are continuing to provide the necessary protection for his employees.

Please contact us if we can be of further service.

Very truly yours,
HARRY E. JAWORSKI
