This is a summary of conditions and actions to help prevent injury to personnel and damage to
the environment and to equipment.
2.3.1 Mechanical Hazards
Lifting limits and guidelines
Note: The load values mentioned in this section are Flowserve recommendations only. All lifting
must be done in compliance with site safety protocol, local regulations, and related industry
standards.
Many precision parts have sharp corners which require appropriate personal protective
equipment during handling. Prior to any attempt to lift an item, employees must first determine
the approximate weight and stability of the load.
• Large, unstable, or awkward loads should always be handled with the assistance of
additional personnel or appropriate mechanical means.
• Loads in excess of 23 kg (50 lb) should only be lifted by appropriate mechanical means
and in accordance with current local legislation or with the assistance of additional
personnel.
• Lifting items less than 23 kg (50 lb) may be prohibited without assistance if the lift is
repetitive and/or awkward (i.e., away from the body, above the shoulders or below the
knees) thus placing excessive stress on the personnel.
