Introduction
1.2.2 General Safe Operation Guidelines (Continued):
The area surrounding the equipment operating area must be clutter-free and free from tripping hazards, or
protruding objects that may snag hoses or cables. Operating surface or drill floor must be kept free of slipping
hazards like grease, oil, water, etc.
Adequate lighting of the work area is required. All warnings, labels, gauges, and signs must be clearly visible.
Equipment components painted green are safe for continuous handling. Areas painted yellow and any other
equipment components that rotate or move are designated as hazardous areas. Contact with those areas must
be avoided during operation.
Always wear all personal protective equipment (PPE) specified by established HSE policies. Follow all safety
guidelines.
Do not open the tong door while the tong is rotating or under load. Doing so may generate a shock load that could
result in catastrophic equipment failure not covered by the manufacturer’s warranty, and may present a hazard to
personnel on the drill floor.

size equipped with the proper dies. Use of incorrectly size dies poses a hazard to personnel and may damage
equipment. Please see Section 3 of this manual for a list of compatible jaw die kits and replacement dies.
