OPERATING REQUIREMENTS.

a. 

A trained operator shall be in attendance at all times when the coin-operated dry cleaning establishment is open. The training of this attendant shall include knowledge of the safe operation of the machines installed and the handling of emergency situations. His telephone number shall be posted conspicuously for emergencies.

b. 

The machines shall be inspected daily and kept in good repair. All maintenance personnel shall be familiar with the necessary machine repairs and instructed as to proper methods of handling perchlorethylene. Access doors to the maintenance area shall be kept locked.

c. 

A step-by-step instruction list must be posted in a conspicuous location near the machine for customer use. Included shall be a list of items not to be dry cleaned.

d. 

Only the solvent and supplies specified by the equipment manufacturer shall be used. No spotting solvents other than water shall be permitted.

e. 

An interlock system must be provided on the machine to prevent the loading door from being opened during the normal cycle.

This system may be either electrical and/or mechanical and so connected that in the event of a power failure or other stoppage during the operating cycle the machine fails safe and the door remains locked and is not operable by a customer.

f. 

The drying time of the operating cycle shall be sufficient so that odor detectable concentrations of solvent vapors are not dispersed with the cleaned garments.

g. 

No open flames or surfaces heated to a temperature over 75° shall be allowed in the service area. Gas appliances may be used in the remainder of the building if they are vented to the outside by noncorrodible pipes.
