What is the primary responsibility of a marine chemist at the beginning of a contract concerning hot work?

The primary responsibility of a marine chemist at the beginning of a contract concerning hot work is to conduct Gas-Free Engineering (GFE) tests to confirm gas-free status. This task is crucial because it verifies that the area where hot work (such as welding or cutting) will take place is safe from flammable gases or other hazardous vapors that could pose a significant risk of explosion or fire.

Conducting these tests involves using specialized equipment to measure the levels of combustible gases in the atmosphere. Only after confirming that the area is indeed gas-free can hot work begin, ensuring the safety of personnel and compliance with safety regulations. This precaution is essential to prevent accidents that could result from ignition sources in an unsafe environment.

Other responsibilities, such as ensuring proper ventilation, inspecting fire safety equipment, or signing the hot work chit, are important aspects of the overall safety and protocol management during hot work activities but occur in conjunction with or after the gas-free status has been established.
