Some safety standards which may apply to inclinometer use
ASME B30.5 Sec. 5-1.9.1(c) (SAFETY STANDARD FOR CABLEWAYS, CRANES, DERRICKS, HOISTS, HOOKS, JACKS AND SLINGS)
"A boom angle or radius indicator readable from the operator's station shall be provided."
ASME B56.6 Sec. 8.5.5 (SAFETY STANDARD FOR ROUGH TERRAIN FORKLIFT TRUCKS)
"A method of indicating boom angle in degrees shall be provided using 0 deg at the horizontal position of the boom and shall be visible by the operator in his operating position."
ANSI A92.2 Paragraph 3.1.3 (AMERICAN NATIONAL STANDARD FOR VEHICLE-MOUNTED ELEVATING AND ROTATING WORK PLATFORMS)
"If the rated capacity of the alternative configuration is related to an angle which a boom makes with the horizontal, then the manufacturer shall install a means by which the operator can determine whether the boom is at an angle, using permanent and legible characters where marking is necessary."
ANSI A92.2 Paragraph 3.1.6 (AMERICAN NATIONAL STANDARD FOR VEHICLE-MOUNTED ELEVATING AND ROTATING WORK PLATFORMS)
"Each aerial device, when properly mounted upon a vehicle meeting the manufacturer's minimum vehicle specifications, and used in a specific configuration, shall comprise a unit capable of sustaining a static load, and and one-third times the rated capacity for that specific configuration, when the vehicle is on a slope of five degrees downward in the direction most likely to cause overturning."

OSHA 1926.1415(a) (CRANES AND DERRICKS IN CONSTRUCTION / SAFETY DEVICES)
"The following safety devices are required on all equipment covered by this subpart, unless otherwise specified...
1926.1415(a)(1) Crane level indicator.
1926.1415(a)(1)(i) The equipment must have a crane level indicator that is either built into the equipment or is available on the equipment."
OSHA 1926.1431(c)(1) (CRANES AND DERRICKS IN CONSTRUCTION / HOISTING PERSONNEL)
"The equipment must be uniformly level, within one percent of grade, and located on footing that a qualified person has determined to be sufficiently firm and stable.
OSHA 1926.1431(e)(2) (CRANES AND DERRICKS IN CONSTRUCTION / HOISTING PERSONNEL)
"The system used to connect the personnel platform to the equipment must allow the platform to remain within 10 degrees of level, regardless of boom angle."
