very minimum required for immediate use and safe efficient operation. Approval of local fire prevention
personnel is required.
T-26. Noise.
Protection against the effect of occupational noise exposure will be provided to technicians when the
sound level exceeds 85 dBa, as stated in TB MED 501. Administrative or engineering controls will be
used to reduce the sound level to within the permissible level. Personnel working in noise-hazardous
areas as defined in TB MED 501 will receive replacement and periodic audiometric evaluations. Also,
these personnel will be fitted, under medical supervision, with hearing protective devices and instructed in
their care and use. Warning placards will be properly posted in noise hazard areas indicating hearing
protection required.
T-27. Cleaning Solvents.
Cleaning solvents for electrical equipment should be carefully chosen. An acceptable solvent is
trichlorotrifluoroethane. Highly toxic and/or highly flammable cleaning solvents, such as carbon
tetrachloride, trichlorethylene or benzene that require special ventilation, storage, and control procedures,
shall not be used.
T-28. Blowers.
Use only rubber or insulating hose in airlines for blowing out equipment. Use the minimum air
