DID YOU KNOW WHEN OBJECTS GO DOWN UNEXPECTEDLY,

INJURIES GO UP EXPONENTIALLY.

The Halliburton 10 to Zero Life Rules are a compilation of basic rules

that all Halliburton employees know and live by. These are key components

for identifying and managing the hazards in our business.

In fact, objects falling on people, (often from heights) do lead to

serious injuries.

We can all decrease falling object incidents by increasing falling

object awareness. Institute procedures for inspecting equipment and

fixtures, and securing tools and loose objects. Establish restricted

areas and post signs under work at height. Institute Stop Work

Authority if theres any doubt about safety. Eliminating injuries from dropped objects should always be a high priority.

At Halliburton, solving customer challenges is second only to keeping

everyone safe and healthy. You can find more safety tips at

Distributed Temperature Sensing (DTS):

Fiber optics-based sensing capability

DTS allows tracking of temperature changes along the entire length of Coiled Tubing

It can be used to analyze distribution of flow:

During an acid job

Hot/Cold slugs

Gas entry points

Cross- flows
