Engineers safety regulations should be consulted for
the most current 8-hour exposure limits.
**************************************************************************
The noise level 304.8 mm 1 foot from a boiler shall not exceed 85 dBA.
This includes the boiler, blowers, compressor, and any other
noise-producing items related to the boiler.
2.2
BOILER DETAILS
2.2.1
Materials
Materials exposed to the internal environment of the boiler shall be
compatible with the temperature and atmospheric conditions which they will
encounter. Dissimilar metals that, when in contact or otherwise
electrically connected to each other in a conductive solution, generate an
electric current, shall not be used in intimate contact.
2.2.2
Lubrication
All sliding, moving, or rotating parts normally requiring lubrication,
except those provided with "sealed-for-life" lubrication, shall be provided
with suitable means for lubricating. Lubrication points shall be readily
accessible and identified by a permanent instruction plate mounted in a
convenient location on the boiler. Equipment shall be designed to operate
efficiently and satisfactorily when lubricated using standard military
2.2.2.1
Lubrication fittings shall be located in accessible protected positions. A
bright red circle shall be painted around each point. Balls, bodies and
tips of fittings shall be carbon steel. Threads of fittings shall be 1/4 -
28 taper, straight or 1/8 pipe threads. Fittings shall incorporate a
surface ball-check valve located at the surface of the inlet tip. All
carbon steel fittings shall be cadmium plated in accordance with ASTM B 766,
Type I, Class 5 or zinc coated in accordance with ASTM B 633, Type I, Class
1 except that the salt spray test period for red rust corrosion shall be a
minimum of 50 hours.
2.2.2.2
Caution Plates
When the use of high-pressure lubrication equipment, 6.89 MPa 1,000 psi and
higher, will damage grease seals or other parts, a suitable warning or
caution plate shall be affixed to the equipment in a conspicuous location.
2.2.3
Lifting Attachments
Each unit shall be equipped with lifting attachments designed and installed
to enable the equipment to be lifted in its normal position without undue
stress on the unit.
2.2.4
Accessibility
All parts subject to wear, breakage, or distortion, and all parts that
require periodic maintenance, shall be readily accessible for adjustment or
replacement.
