OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov.

RE: Your letter dated July 27, 1976, Exits for Unattended Buildings
Dear Mr. Akerstrom:
Your letter to our Peoria, Illinois Area Office has been referred to this office for response.
Small buildings as described in your letter, 500 to 1,000 square feet in size, would not be required to have two exits.
The provisions of the National Electrical Code 1971 will apply to the battery installation. Please refer to Article 480-7(b) which requires that, "Provision shall be made for sufficient diffusion and ventilation of the gases from the battery to prevent the accumulation of an explosive mixture in the battery room."
While permanently installed eye wash facilities are preferred, we recognize that the installation of such facilities is not always feasible or practical. In buildings such as you describe where employees are present only on rare occasions, we would accept the use of portable units.
Very truly yours,
NICHOLAS DiARCHANGEL
Acting Regional Administrator
for Occupational Safety & Health
