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.

Dear Mr. Lawrence:
Your letter to the Federal Trade Commission dated August 31, 1977 has been referred to me for a response.
As Mr. Barto, Chief, Division of Occupational Safety Programming indicated in his October 12, 1977 letter, only OSHA construction standards (29 CFR 1926.906(9)) specifically require the use of silver chloride dry cells as a power source for testing electric blast caps. OSHA General Industry Standards (29 CFR 1910.109(e)(4)(vii)) do not contain such a requirement. Moreover, to the extent that the Mining Enforcement and Safety Administration (MESA) has exercised jurisdiction in mines over the hazards which you have addressed, OSHA standards would not apply.
I am forwarding this letter to Dr. Bingham's office so that it will be made part of the record on the petition to amend the relevant construction standard.
Let me assure you that your comments will be carefully considered before any decision on this matter is reached.
Benjamin W. Mintz
